摘要： 619,464. Delivering measured quantities of liquids. IMPROVED DESIGNS, Ltd., READ, N. K., and READ, H. L. Dec. 12, 1946, No. 36668. [Class 106(v)] Apparatus for delivering measured volumes of liquid comprises a measuring chamber, valve means for the supply and discharge of liquid, mechanism to control the said valve means while allowing of sufficient time for filling and emptying the chamber, means for setting in motion the said mechanism which then functicns automatically for the remainder of the cycle of operations and governor means for controlling the rate of operation of the mechanism. As shown in Fig. 1, depression of a plunger 22 causes cam 38 to disengage pawl 36 from ratchet wheel 35 mounted on a spindle 34 which then rotates under the force of a clock spring (not shown), mounted on spindle 30 and driving the spindle 34 through gears 32, 33. Rotation of spindle 34 turns a cam disc 39 causing a lever 42 to pivot so that its locking lug 43 engages a recess 45 in the plunger and holds the latter depressed. The spindle 34 drives a centrifugal governor 48 through a gear train 47 and also drives the pin wheel 49 of a Geneva mechanism (Fig. 4), spur wheels 54 being connected one to the inlet valve 15 and the other to the discharge valve 16 of the measuring chamber. During one complete revolution of the pin-wheel 49 the discharge plug valve 16 is turned to close and the inlet plug valve turned to open, a pause then occurs during which the measuring chamber fills, valve 15 is then closed and valve 16 opened and finally a further pause is allowed whilst the measuring chamber empties. The spindle 34 having then completed one revolution, the dwell on the cam disc 39 again registers with the end of the lever 42 which pivots away from the plunger 22, releasing the latter which returns to its original position and allows the pawl 36 to re-engage the ratchet wheel 35, thus stopping the mechanism. The capacity of the measuring chamber may be varied by insertion within the glass cover (not shown) of spacing rings, blocks, etc. Depression of the spindle 22 and consequent rotation of the spindle 30 winds the clock spring at the commencement of each cycle of operations. In a modification, the apparatus may be arranged to empty the measuring chamber on initial operation of the spindle 22, the chamber then refilling ready for subsequent use.

摘要： 467,488. Screw propellers. DELL, C., and READ, H. L. Sept. 17, 1935, Nos. 25798/35 and 12174/36. [Class 114] In screw propellers of the kind in which the hub is mounted for limited relative rotation and axial sliding on the draft for varying the pitch under varying thrust and torque, the hub assembly connecting the blades to the shaft provide that increases in thrust and /or torque reduce the pitch angle whilst decreases result in increased pitch. The boss 1 is mounted with limited relative rotation on a sleeve 3 which is splined to and has a limited sliding motion on the propeller shaft. The boss is also connected to the shaft by cam slots 6 engaging rollers 5 on studs 4 on the shaft. The sleeve 3 is formed with a bevel wheel 7 meshing with bevels 8 on the roots 9 of the blade. Sliding motion of the sleeve 3 is restrained by springs 12 and by liquid pressure acting on pistons 10. Pressure fluid under the control of the pilot is admitted by a central duct 13 past the valve 13 to the inlets 18. With a constant pilot valve setting the pressure depends upon the engine speed. The valve 15 may be omitted. In a modification, the pistons 10 act only as dashpots or may be omitted. A single annular piston mav be used in place of the two pistons 10. The cam slots may be formed in a flange connected to the hub through an intermediate ring which permits of a vernier setting relative to the hub.

[Class 40 (v).] The anode circuit of a valve C operates a relay H, switch, recording device or the like. The grid of the valve is connected to a point in the circuit between a fixed resistance B and a light-sensitive cell A, and its mean potential is adjusted by a potentiometer E. The valve derives its filament and anode supply from the direct or alternating current source FG. When alternating current is employed, the relay coil H is shunted by the condenser I. Reference has been directed by the Comptroller to Specification 287,596, [Class 40 (v), Wireless signalling &c.].

摘要： 449,707. Hydro-mechanical variablespeed gearing ; slipping clutches. DELL, C., Muros, Hall Park Gate, Berkhamsted, Hertfordshire, and READ, H. L., Netherton, Herington Grove, Hutton Mount, Essex. March 28, 1936, No. 9720. Addition to 434,204. [Class 80 (ii)] In automatic variable - speed gearing as claimed in the parent Specification, a mechanical clutch 12, automatic or manual, is arranged between an epicyclic element 9 and the secondary element 2 of the hydraulic coupling. The gearing now comprises a driving vanewheel 1, a secondary vane-wheel 2, connected to a loose annulus 9 through the clutch 12, an interposed vane-wheel 3, directly connected to a loose sun-wheel 4, and a planet carrier 6 integral with the driven shaft 7. The clutch comprises a double conical member 12, integrally connected with the secondary wheel 2, and frictionally gripped between opposed conical members 13, 14, connected to the annulus 9, and loaded by springs 15. The members 13, 14 have inclined surfaces 21, Fig. 2, engaging rollers 19, carried by a drum 16, prevented from reverse rotation bv a one-wav detent 17. Under excessive load, such as the backward reactionary load on the annulus 9 at starting, the inclines 21 ride up the rollers 19, thereby separating the members 13, 14 and disengaging the clutch. The secondary wheel 2 is thus able to continue its forward rotation, and undue heating of the hydraulic fluid due to its being brought to a standstill is avoided. According to the Provisional Specification, the declutching is effected by axial sliding of the secondary wheel, under the influence of a lever system, and such sliding also clutches the secondary wneel frictionally to the vane-wheel 3.

摘要： 434,228. Hydraulic transmission of power. DELL, C., 25, Swing Gate Lane, Berkhamsted, Hertfordshire, and READ, H. L., Netherton, Herington Grove, Hutton Mount, Essex. May 15, 1934, No. 14648. [Class 69 (ii)] In hydraulic transmission devices of the F÷ttinger type, a chamber containing liquid and air is formed by a clearance between the casing and a vane wheel, and means secured to the element on the driving shaft are provided in the chamber to aid centrifugal action in pumping liquid over the back of the vane wheel into the working chambers when the pressure in the latter permits. The means may consist of spiral fins or grooves 4, Figs. 1 and 3, provided on the back of the vane wheel or the opposing internal casing wall, and the chamber, when the casing is a fixed one, may have a gravity tank or other external source of supply. The invention may be applied to the transmission system described in Specification 434,204.

摘要： 413,802. Frictional epicyclic gears. DELL, C., 25, Swing Gate Lane, Berkhampsted, Hertfordshire, and READ, H. L., Netherton, Herington Grove, Hutton Mount, Essex. March 7, 1933, No. 6891. [Class 80 (i).] A frictional epicyclic gear comprises a sun 13 on the driving shaft, an annulus 1 in the casing 2, and a planet carrier 14 on the driven shaft with rollers 15. The planet and sun are positively locked and adjusted by axial movement relative to the annulus by means of the threaded rings 18 and 19. The planet carrier 14 has radial slots 21 to take the planet axles 20 and narrower and deeper slots between these axle slots to render it slightly resilient. The rollers 15 may be frustro-conical or curved so that the sun and planet system are mutually interlocked when assembled.
