摘要： According to principles of this invention, the photoelectrochemical effect (“PE effect”) may be greatly reduced or eliminated, even when an electrode is immersed in an electrolyte and exposed to light, by using a transparent conductor to record electrical activity. Thus, an electrode with a clear conductor may be used to accurately record electrical activity of neurons and other cells that are exposed to light in vivo or in vitro. Such an electrode eliminates or greatly reduces the artifacts that would otherwise be caused by light due to the PE effect.

摘要： 418,410. Changing signs. EITZEN, A. D., Rockville Centre, New York, U.S.A. Nov. 17, 1933, No. 32095. [Class 3 (i).] In a telegraphic system having a tape-printing transmitter and one or more tape-printing receivers an exhibiting area is provided at the transmitting and receiving stations through each of which areas passes the respective tape, the areas being of such size and so arranged that at any instant the matter contained on the portion of tape within the area at the transmitting station is the same as that upon the tape within the corresponding areas of the receiving stations, and is directly visible on the area at the transmitting station, but is projected from the areas at the receiving stations on to a screen or the like. Typewriters 1, 4, Fig. 6, of substantially the same design are connected by wiring 5 so that messages &c. typed on the transmitter 4 are typed by the receiver 1 and exhibited on a screen 70 by a light-projection system, the operator of the transmitter 4 being able to visualize what is projected on the screen by looking at an area of the tape which is within a frame 120 mounted in brackets 123 above the platen of the transmitter. The receiver 1 has supporting walls 7, 8, Figs. 2 and 6, provided with extensions 9 on which is adjustably and pivotally mounted a lamp housing 14 provided with a light aperture 42 in front of which the tape T moves after leaving the platen 40 of the typewriter 1. The tape passes from a supply roll 101 mounted on the rear upper end of the typewriter 1, over an idler roll 102, down and around the platen 40, under a guide 43 and across the light aperture 42, over a rubber-faced feed roller 90, Fig. 3, under a feeler-roller 45, and then to a rewind reel R. The roller 45 is mounted on arms 46 pivoted at 47 and is movable to apply brakes 62 to brake drums 55, 59 on the rewind reel R when the tape T becomes taut due to the stoppage of the feeding means on the typewriter. A shaft 49 connected to the brake drum 55 is driven from a motor 6 by a spring belt 51 and sheaves 50, 52. For pulling the tape T a line space in synchronism with the typewriter 1, the line-feed bell-crank lever 71 of the typewriter, which is depressed when the tape T is advanced, is adapted to engage a lever 76, pivotally mounted on a bracket 73 secured to the platform 2 of the typewriter, this lever 76 being pivotally connected to an adjustable link 78 pivotally connected to a lever 79. The lever 79 is pivotally connected at 80 to a bracket 81 fixed on the extension 36 of the lamp housing 14, and its free end has a ball-andsocket connection 82 with one end of a bracket 83 pivotally connected at 84 to the extension 38 of the housing 14. The upper end of the bracket 83 is pivotally connected to a pawl 85 which engages under spring action a ratchetwheel 86 fixed to the feed-roller 90. A second pawl or latch 88 co-operates with the pawl 85 to form a step-by-step escapement. The tape T is held in engagement with the feedroller 90 by pressure rollers 93, 94, 95 mounted on levers 96 pivotally mounted on a rod 97, the levers being urged towards the roller 90 by springs 98 coiled around the rod 97. For withdrawing the pressure rollers to allow a new tape to be threaded through the machine, an arm 100 which is connected to a U-shaped bracket 99 may be manipulated. The connecting means between the bell-crank lever 71 and the ratchet-wheel 86 are such that the feedroller 90 will pull the tape at a slightly faster rate than it is fed by the platen 40, so that the tape is taut across the light aperture 42. The type-bars are each provided with lower and upper case types. In order to effect printing with an upper-case type the platen 40 is moved upwardly, in which case a loop 104 is formed between the platen and the lower edge of the extension 38 of the lamp housing. A device for holding the tape taut across the light aperture 42 when such a loop is formed comprises two rows of discs 108, 115, formed on shafts 105, 114 respectively, which engage the tape at the entrance and exit of the light aperture, both shafts being held in open-ended bearings by springs 116, 117. The frame 120 of the transmitter 4 is adjustably mounted in the brackets 123, and has U-shaped channels at the sides to guide the tape, and an upper and a lower wall. The frame is anchored by setscrews to the brackets at a distance from the platen corresponding to the position of the light aperture 42 of the receiver 1. The transmitter is preferably provided with feeding, pulling, and guiding mechanism as in the receiver. The lamp housing 14 of the receiver 1 comprises a lamp 26, a reflector 23, and condenser lenses 27, 37, and 39, the lenses 37, 39 being cut away to allow the housing to be lowered as near as possible to the platen 40. The lower wall 19 is perforated to permit air from the outside to enter the housing and the end wall of the cover C is provided with a chimney extension 35, Fig. 6, so that the heated air at the top of the housing can be rapidly withdrawn to prevent the formation of heat waves in the housing, and so prevent flickering on the screen 70. An arm 63 formed on the extension 38 of the lamp housing carries an objective lens through which the light passes from the condenser 39 to a mirror or deflector 65 supported on a bracket 66 pivotally mounted at 67 to the extension 68. From the mirror 65 the light rays are directed upwardly on to a mirror or deflector 69, from which they are projected on the screen 70.

摘要： 403,004. Changing signs. EITZEN, A. D., Rockville Centre, New York, U.S.A. May 4, 1933, No. 13023. [Class 3 (i).] Optical-projection apparatus.-A stock quotation projection machine is provided with a device for pulling the tape across the light aperture, driving means for the tapepulling device, and a tension device for imitiating the actuation of the tape-pulling device independent of the driving means and provided with electrical contacts which the tension device, after it has initiated the actuation of the tape-pulling device, operates to cause that actuation to be taken over by the driving means until the tension of the tape is increased beyond a predetermined amount. The tape T, Fig. 1, passes from a ticker mechanism 1, across the light aperture of the projection machine 2, around a pulley 14 and a pressure roller 15, around a finger 23 of a pivoted brake arm 24 bearing on a brake drum 26, and is rewound on a reel 4 attached to the drum 26. A member 13 dissipates the vibrations in the tape prior to its passage across the light aperture. The roller 15 is mounted on a pivoted arm 16 which is influenced by a spring 20 towards the pulley 14, with which it is concentric. A continuously-rotating motor 40, Fig. 7, drives through a belt 37 and pulley 38 a combined pulley 36 and magnetic clutch member 43 loosely mounted on a shaft 35. When the clutch member 43 is energized it attracts, against the action of an interposed spring, a disc 41 secured to the shaft 35 so that the latter is rotated to drive through a pinion 34 and gear 33 the shaft 32 on which the pulley 14 is loosely mounted. The shaft 27 of the reel 4 and brake drum 26 is mounted on an extension 22 of the machine 2 and is driven from the shaft 32 by pulleys 29, 31 and a spring belt 30. The clutch member 43 is provided with collector rings 45, 46 engaged by brushes 50, 47 respectively, and the pulley 14, Fig. 3, is provided with collector rings 53, 54 engaged by brushes 52, 55 respectively, the brushes 47, 55 being connected to electrical mains by a plug 49. The ring 54 is connected by a conductor to a contact 58 mounted on the cylindrical portion 59 within the pulley 14, and the ring 53 is connected by a conductor with a contact 61 (not shown) mounted on the free end of an arm 62 attached to a hub 66 fixed on the shaft 32 within the pulley. The hub 66 has connected thereto one end of a coil spring 67 coiled around the shaft 32, the other end of the spring being secured to the disc portion 68 of the pulley 14. When the ticker 1 starts operating and feeding the tape T, assuming the contacts 58, 61 to be open, the tension in the spring 67 will first act on the pulley 14 to bring the contact 58 into engagement with the contact 61 ; thereupon current passes from the mains through the brushes 55, 52 to complete the circuit through the magnetic clutch 43 to energize it and attract the disc 41, whereupon the motor 40 drives the shaft 32 which rotates the pulley 14 through the intervening spring 67. When the ticker stops feeding the tape T therefrom the pulley 14 stops, but the arm 62 therein continues to rotate with the shaft 32 so that the contact 61 leaves the contact 58 ; the circuit through the magnetic clutch 43 is thus broken, the disc 41 released from driving connection therewith, and the shaft 32 and arm 62 are brought to rest. A control or governor mechanism to prevent the spring 67 from actuating the pulley 14 too suddenly when the ticker 1 starts consists of a gear 70 mounted on the shaft 32 for one-way rotation in the opposite direction [opposite] to the latter, and in mesh with a considerably smaller gear 72 mounted on a shaft 73 carried by a housing on the pulley 14. Centrifugal friction shoes 79, 80 on the shaft 73 are situated in the housing. The projection machine 2 is of the type having a lamp housing 5, an extension 6 provided with the light aperture, and an objective lens 7 secured by a bracket 8 to the part 6 over the light aperture. The images are directed on to a screen 12 by two inclined mirrors. In a modification the driving motor is started and stopped with the ticker since no clutch device is provided and the contacts within the pulley 14 control the motor circuit.

摘要： 463,379. Type - printing telegraphy. EITZEN, A. D. Aug. 14, 1936, No. 22430. [Class 40 (iii)] [Also in Group XVI] A stock ticker having a tape feed is combined with a device for disabling the tape feed to release the tape after the ticker comes to rest, and with a tape-pulling device for drawing the tape from the ticker when the tape feed is disabled. The ticker is described as combined with a projection apparatus, and the purpose of the invention is to ensure that when the ticker stops printing, the last-printed quotation on the tape will be projected on to a screen. The tape T passes from the supply reel 10 in the stock ticker 11, between a feed roller 13 and pressure roller 14, over guides 15, 17, across an extension 2 of the projection apparatus, under a guide roller 22, over a tapepulling roller 24, and then under a guide roller 26 to the rewind wheel 27. The finger of a weighted lever 19 pivoted on the extension 2 bears on the tape just before it passes over the extension 2 to damp down the vibrations in the tape. A motor 37 drives through reduction gearing the tape-pulling roller 24, and the rewind reel 27 is driven from the reduction gearing through a spring belt. The pressure roller 14 in the ticker 11 is pivoted and spring-pressed towards the driven roller 13, and is adapted to be drawn away from the roller 13 when a magnet 43 is energized. The two terminals of a tiltable mercury switch 50 are connected to the supply mains 61, 62, the motor 37 is connected to one terminal 66 of the switch 50 and to the supply mains, the magnet 43 is connected to the terminal 66 of the switch 50 and to a terminal 57 on a further mercury switch 53, and the other two terminals on the switch 53 are connected to the supply mains and a magnet 74. The switch 53 is mounted on a bracket 54 pivoted at 55 to move through a limited arc. Pivoted on the bracket 54 is one end of a lever 71 the end 16 of which bears on the tape T between the guides 15, 17 to form a loop in the tape. The magnet 74 is mounted on a bracket 76, and an armature lever 78 is pivoted on the bracket at one end and connected at the other end by a spring 84 to the switch 50 which is pivotally mounted on the same bracket. A spring 80 tends to force the lever 78 away from the magnet 74. The lever 78 is connected by a link to the piston of an oil dash-pot 90, the piston being allowed free downward movement, but only a slow upward movement. In operation, when the ticker 11 begins to print and discharge tape, the tape will form a loop to permit the finger 16 to descend and thus move the bracket 54 about its pivot, whereupon the mercury in the switch 53 will connect only those terminals thereon which energize the magnet 74. The magnet 74 attracts the armature lever 78 which rocks the switch 50 to cause its two terminals to be bridged by the mercury and consequently the motor 37 is started to initiate the tapepulling operation. When the ticker stops printing, the loop in the tape is absorbed so that the finger 16 ascends. The bracket 54 is then moved, the connection between the switch 53 and the magnet 74 is broken, and the magnet 43 is energized to withdraw the pressure roller 14 from the roller 13. The tape-pulling roller 24 will continue drawing the tape T during the slow upward movement of the lever 78 and until the switch 50 is tilted sufficiently to break the connection to the motor 37. The time taken for the latter operation is sufficient to allow the last printed quotation to reach the light aperture to be projected on to the screen 8.

摘要： 411,306. Feeding webs. EITZEN, A. D., Rockville Centre, New York, U.S.A. July 4, 1933, No. 19013. [Class 100 (i).] A mechanism for drawing the tape derived from the ticker of a stockquotation projection machine across the light aperture thereof, comprising a tape puller for pulling the tape across the light aperture and a motor, is characterized by the provision of a variable-speed controlling- device which operatively connects the motor to drive the tape puller, and which includes an elongated lever engaging the tape at the anterior end of the light aperture and extending to the posterior end thereof, the arrangement being such that the lever is moved by the tape, when the tension thereof varies, to operate the speed-controlling device. The tape T, Fig. 1, passes from a high-speed ticker 1 under the finger 10 of a lever 11, over a roller 12 at the entrance end of the light aperture 3 of the projection machine 2, over a smooth-faced tapepulling roller 4, and around an idler roller 5 to a rewind reel 6. The roller 4, lever 11, and reel 6 are all part of a centralized unit associated with a casing 13 which can be removed from the projection machine 2 by removing two screws. A continuously-operating motor 18 on a support 19 drives a shaft 23, Fig. 3, mounted in the casing 13, by means of a belt and pulleys, and a worm 28 on the shaft 23 meshes with a worm-wheel 29 mounted on a stub shaft formed on a boss in the casing. A flange 33 formed on an internally-threaded member mounted on a shaft 35 is normally spring-pressed to engage frictionally the side of the worm-wheel 29 to constitute a slip-clutch for driving the tapepulling roller 4. The shaft 35 has mounted thereon a worm-wheel 37 which meshes with the worm 38 on a vertical shaft 39. The shaft 35 extends through the casing 13 and carries the pulling-roller 4 which is connected by a spring belt 90 to the reel 6. The worm-wheel 37 is provided with an extension at the side which forms a seat for one end of the spring which turns the flange 33 about the shaft 35 to frictionally engage the worm-wheel 29. When the worm 38 comes to rest, and thus brings the worm-wheel 37 and shaft 35 to rest, the continuing rotation of the worm-wheel 29 will cause the flange 33 to rotate in the opposite direction to the tension of the spring to disengage it from the worm-wheel 29. The rotation of the worm 38, and thereby the shaft 35, is controlled by a governor-mechanism comprising a collar 46, fixed on the shaft 39, carrying two spring arms 47, 48 having weights 52, 53 thereon, the spring arms being secured to a collar 49 slidably mounted on the shaft 39, and the collar 49 having formed at its upper end a disc 54 adapted to engage a face 55 of the top plate of the casing 13. The lever 11 is fixed on a shaft 61 mounted in the casing 13, and when the lever rises due to the tightening of the tape T, caused either by the stoppage of the ticker 1, or by the excessive speed of the pulling-roller 4, it rotates the shaft 61. A cam 62 mounted on the shaft 61 then lifts a pivoted lever 64 which presses the disc 54, against the action of the rotating weights 52, 53, into frictional engagement with the face 55, to slow down or finally stop the rotation of the shaft 39. The centre of gravity of the lever 11 is close to the pivot shaft 61 and the lever 11 is thus very sensitive to the variations in the feed of the tape T. The lever 11 comprises a weighted portion 70 secured by a screw to a light portion 71. The tape is held in engagement with the roller 4 by an idler 72 journalled in arms which are pressed towards the roller 4 by a coil spring mounted on the pivot of the arms. One of the arms has a finger-piece to facilitate withdrawal of the roller 72 from the roller 4. The re-wind reel 6 preferably consists of two discs 80, 81, Fig. 5, the latter disc being mounted on the shoulder of a hub 83 mounted on ball bearings on a pin 86, and the former disc being mounted on a hollow cylindrical member 93 adapted to slide over the hub 83 and engage the latter by a pin-and-slot connection. The member 93 has a head 96 within which is secured a wire finger 97 which extends over the outer face of the member 93 to secure the end of the tape on to the composite reel. When the reel is full the member 93 and disc 80 can be detached from the hub 83 by a simple turning movement. The images of the marks on the tape are projected by an objective lens 7 and a mirror 8 upon a screen 9.
