摘要： 486,313. Lavatory basins. COCKBURN & CO., Ltd., M., and BROWN, J. Dec. 1, 1936, No. 32985. [Class 26] A wash-hand basin particularly one of por celain - enamelled cast iron, is provided with a detachable shelf sup ported by a wall on the back of the basin anc by a part of the back wall projecting later ally of the wall and with means for fastening the shelf to the basin. The basin is formed with a ledge 11, Figs. 1 and 3, hollowed to form a soap-tray 12, and with a rear wall 15, formed into a central buttress 16, and provided with turned-over top edges 18 extending from each side to a point just above the soap tray 12. Between the edges 18 lies the shelf 19, engaging three projections 22, 23, 22 on the wall 15 and buttress 16, and provided with locating projections 28, 29 to lie against the projections 22, 23. The shelf is formed with a rim 20 and draining passage 21. It is held in position by a nut and a square headed screw 26, engaging a slotted U-shaped lug 25 on the shelf and passing through a lug 24 on the basin.

摘要： 481,448. Fire-alarm systems. AUTOMATIC ELECTRIC CO., Ltd., (in Liquidation), and BROWN, W. J. Sept. 10, 1936, No. 24725. [Class 40 (i)] In a fire-alarm system of the type wherein a plurality of signal boxes is included in series in a loop circuit over which direct current is normally flowing, any one of the boxes may be called selectively from the central station by transmitting a numerical code of A.C. impulses. The system comprises signal boxes SS1 ... SS10 connected in loop circuit to a central station having a tape register RE and gong G for signalling the locality of a fire. A step-by-step calling magnet M is connected to each box through a condenser and is made responsive to A.C. impulses by a rectifier. The calling impulses are transmitted from a transformer TR under the control of a keyboard 1 .. 11 and finder switch S. Depression of a key to call a particular box marks a contact in the bank of wiper S2 and pulls up relay X which initiates the cyclic operation of relays X, W for driving the switch. A relay P is impulsed at alternate steps to send A.C. impulses over the loop and operate the stepping devices in the boxes simultaneously. When the marked contact is reached relay K pulls up and stepping is terminated. Under these conditions, the stepping device at the called station closes the circuit of the calling lamp L. For checking purposes a pilot lamp is operated over the wiper S3 and a stepping device M1 at the central station is operated simultaneously with the selecting devices at the boxes. The system is combined with a telephone system and when a box is called, and the box door is opened, resistance is automatically inserted in the loop circuit to cause the release of an alarm relay T. The system is then ready for the connection of the central station telephone equipment across the loop. At the conclusion of conversation, the operated selecting key is restored and the switch S hunts to its home position, the selecting devices in all the boxes being homed simultaneously. A general call to all boxes may be sent by transmitting a particular code. " Faulty conditions " working. If a break occurs in the loop a relay EW (not shown) is released and the two legs of the loop are connected in parallel to one side of the battery BA the other pole of which is earthed. If the break is not earthed the selective call system is not interfered with, but if earthed, relay LA or LB will be reoperated and the stepping magnet SM of the switch S is isolated to prevent its operation. Under these conditions impulses are transmitted over lead 11 to a fault alarm. Specifications 431,349, [Group XXXVII], and 471,759 are referred to,

摘要： Acetic anhydride is produced by bubbling acetic acid vapour through molten boric anhydride at a temperature above 800 DEG C. If a catalyst such as aluminium or titanium oxide is added to the molten mass, the reaction may be effected at a lower temperature. In an example the boric anhydride is contained in an externally heated graphite crucible at 870 DEG C.; in a second example the temperature is 930 DEG C. Specifications 194,719 and 279,070, [both in Class 2 (iii), Dyes &c.], are referred to.

摘要： 357,842. Transferable containers for vehicles. BROWN, F. A. J., 11, Chertsey Road, Redland, Bristol. Nov. 12, 1930, No. 34097. [Classes 103 (iv) and 108 (i).] A transverable container for railway and other vehicles comprises an open-topped receptacle with a sliding door f, shackles g, h being provided for attaching lifting tackle. The sides and door are provided with straps c and the door opening is bounded by plates k and hoop o. Dogs mare hinged to the door and are provided with tongues n adapted to engage below the loop o and lock the door in position. The door is released by levers v having cam projections v and is adapted to slide vertically to enable the contents to be discharged. Pintles t, u at the sides of the top and bottom of the door serve to guide the door. The bottom of the door when closed is flush with the floor of the container and in front of it the bottom of the door straps c being bevelled off to prevent interfering with the complete closing of the door.

摘要： Ethylidene diacetate is separated from the reaction product obtained by treating acetic acid with acetylene in presence of a catalyst, by agitating with an aqueous solution of a salt of higher density than ethylidene diacetate and allowing the mixture to separate into two layers, the aqueous layer being rejected. Suitable salts are sodium acetate and sodium sulphate. The separated ethylidene diacetate may be dried by treatment with anhydrous sodium or potassium acetate.

摘要： 323,314. Brown, W. J. Nov. 14, 1928. Variable-speed epicyclic, gearing is controlled by two hydraulic clutches 13, 13a and a one-way detent 19 of suitable form. There is a sun gear 1 fast on driving-shaft 2 and a larger sun gear 11 fast on driven shaft 10. Triple planets 3 mesh with these gears respectively and with an internal gear 6 fast to a loose drum 7 adapted to be engaged by clutch 13a. The planet gears are carried by a disc 5 with a flange adapted to be engaged by clutch 13. The clutches are similar and comprise radial cylindrical cavities in a common block 12, the cavities containing pistons impinging upon shoes 15, 15 which run round upon eccentrics 16, 16a upon the outer members, whereby the pistons are reciprocated. The block 12 is connected through a sleeve 17 to a revoluble part of a detent 19. Oil from a reservoir 26 passes along inside a sleeve valve 20 and into the clutch cavities. In the configuration shown, the pistons all move freely and there is no drive. When valve 20 is moved a step to the right by lever 22, the oil in clutch 13 is trapped so that disc 5 is kept from turning backwards by detent 19. The triple gears 3 turn on fixed axes, yielding lowest speed. A further step to the right of valve 20 opens clutch 13 and closes clutch 13 . Drum 7 is held fast and the planets 3 roll round on it so as to drive gear 11 at middle speed. On further movement of valve 20, clutches 13, 13a are both closed and detent 19 overruns, the gearing turning solid on highest speed.

摘要： 276,598. Pell, W. Guy-, and Brown, S. J. May 14, 1927. Percussive hand tools. - The striker 7 is mounted at one end of a lever 9 pivoted at 10 and moved by a cam 17 against an adjustable spring 12 the stroke of which is less than that of the striker. The cam consists of a buttress threaded worm coacting with a correspondingly shaped rack 16 and is rotated by a handle 18. Rotation of the tool holder is also effected by the same worm, which engages a worm wheel 24. In a modified form the tool holder may be pivoted to the lever 9, which may be constituted by a leaf spring.
