Abstract: 558,824. Springs. SEAMARK, L. M. C. Aug. 25, 1942, No. 11953. [Class 108 (iii)] [Also in Group XXIX] A rotary valve comprises a longitudinally slotted tubular sleeve a with the opposite faces of the slot formed with complementary grooves to provide a cavity to recieve a spring device for expanding the sleeve, means being provided for compressing the spring device during the first part of the actuating movement to facilitate the rotation of the valve. In the form shown in Fig. 1, the upper end of the sleeve a is formed with a pair of projections b, c the projection b being divided by the slot off which continues to the lower end of the sleeve. The spring device, which engages part cylindrical grooves in the opposed faces of the slot, comprises a forked pin d having at a point somewhat below its middle a boss e of substantially circular shape in transverse cross-section. In the form shown in Fig. 8 the spring pin is difurcated at both ends and the upper arms are formed with recesses d<SP>2</SP> to facilitate its removal from the sleeve. The actuating spindle f is provided with a heavy flange f<SP>1</SP> provided with recesses to co-operate with the projections. On rotating the spindle one face of the recess co-operating with the projection b engages one face of the projection at the end of one of the short pins mounted in holes e<SP>1</SP> to compress the spring device and release the sleeve, which is then easily rotatable by the engagement of one face of the other recess with the projection c. The upper face of the flange f<SP>1</SP> has a groove with an outer vertical face and an inner inclined face adapted to receive a packing ring f<SP>6</SP> of similar shape. Springs i housed in recesses <SP>2</SP> in the sleeve press the sleeve and flange apart. A pin f<SP>3</SP> is screwed into a detachable cover g co-operates with an arcuate groove in the flange to limit the rotation of the spindle. The ports in the cylindrical cavity in the casing may be elongated to match the ports x on the sleeve and the passages leading from these ports may gradually merge into circular ports on the flanges. The line joining the casing ports may be offset from the axis of the sleeve.

Void [Published under Sect. 91 of the Acts]. [Class 39 (i).] Cathodes of radio-transmitting valves and other high-power tubes are activated by the metallic vapour process and the substances producing the vapour are provided on one or more carriers not connected with the working electrodes and each having a separate lead sealed through the stem of the tube. Barium vapour may be produced from metallic barium, from reaction mixtures or from decomposable compounds. The carrier is heated by high-frequency currents and barium is deposited on the cathode by connecting the carrier to a voltage sufficiently high to heat it by electron bombardment and to direct the barium ions to the incandescent cathode. Simultaneously, the anode or other electrode may be freed from gas by connecting the anode to the same voltage as the carrier. Excessive 'heating of the carrier during working is avoided by mounting the carrier out of the electron stream and providing it with cooling ribs.

Title: Control mechanism for variable pitch propellers
IPC: B64C11/42
Filed: 1953-05-05
Abstract: 724,855. Variable-pitch screw propellers. GENERAL MOTORS CORPORATION. May 5, 1953 [May 21, 1952], No. 12406/53. Class 114. In control mechanism for variable-pitch propellers comprising a feed back mechanism for repositioning a control element, a driving member and a driven member have associated with them means which preclude transmission of movement therebetween for a predetermined movement of the driving member. As described the propeller pitch is governed automatically over a range of angles, e.g. from 10 degrees to 50 degrees and the repositioning means are rendered ineffective over this range, adjustment in the range above 50 degrees being manual and the repositioning device being operative. In the automatic range, pressure fluid from a line 7 supplied by a pump 5 is controlled by a valve 8, actuated by centrifugal force acting against a spring 30, to operate a pitch motor 18, there being a selector valve 11 between the valve 8 and the motor to connect the latter alternatively to the former or to a "beta" distributer valve 9 which controls the motor in the range above the automatic range. Movement of a hand lever 19, which may also vary the tension of the spring 30, raises the piston 49 of a selector valve control valve 10 admitting fluid from the pressure line 7, along a line 65 into the valve 10 and out along a line 51 to the top of the selector valve to depress the piston 60 thereof and cut off the lines 12, 13 from the governor valve 8, the movement also opening up to the lines 14, 15 which leads to the motor 18, lines 16, 17 leading to the "beta" valve 9. The lever 19, by a quick thread device 43 also displaces a lever 22 engaged by a cam 38 on the plunger 37 of the "beta" valve to connect the pressure line 7 to either the line 16 or the line 17 to actuate the pitch motor 18. The feed back mechanism to be described then moves the opposite end of the lever 22 to restore the valve plunger to its normal position. To this end there is mounted on the propeller hub a feed-back ring 73, Fig. 3, rotated by the turning of the propeller blades. The ring has a flange 74 which is toothed at 75 over part of its circumference and flanged at 76 over the remainder. In the automatic range, the flange 76 engages a flat on an extension of a pinion 85 and positively prevents its rotation. In the "beta" range, the teeth 75 engage the pinion to rotate it and through it a shaft 90 which actuates a second quick thread device 45, Fig. 2, to restore the plunger 37 of the "beta" valve to its neutral position.

Abstract: 373,282. Motor road vehicles. BURNEY, SIR C. D., 8, Broadway, Westminster. Nov. 10, 1930, Nos. 12638/32 and 12639/32. Divided on 373,234. Drawings to Specification. [Classes 79 (ii), 79 (iii), 79 (iv), and 79 (v).] Relates to rear-engine driven road vehicles such as described in Specification 320,725*, [Class 79 (iii), Motor vehicles, Arrangement &c. of parts of], and comprises an arrangement wherein the driving elements, embodying an engine and variable speed mechanism mounted in a frame yieldably supported on the road wheels, are disposed partly or entirely behind the axis of the rear wheels, the drive to the rear wheels being taken in a substantially horizontal plane through articulated means, keeping the centre of gravity low, and the weight of the driving elements being so distributed along the length of the frame as to being the position of the centre of gravity to a point between 25 per cent and 45 per cent of the length of the wheel base in front of the axis of the rear wheels. The invention also comprises the arrangement of the engine, clutch, gear-box and differential as a single driving or power unit with its axis disposed more horizontal than vertical, the engine being located partly or entirely behind the axis of the rear wheels and the gear box, with or without the clutch, on the forward side of the wheel axis, the drive being taken through articulated means to the rear wheels. An object of the rearward disposition of the centre of. gravity, the preferred position of which is about one-third of the length of the wheel base in advance of the rear wheel axis, is to obtain substantially equal adhesion of all four wheels under conditions of maximum deceleration due to braking. Further, in order to obtain inertia balance in relation to transverse percussion effects or forces, such as in passing.over obstacles on the road or in steering or turning, and with a view to preventing skidding, the weight of the driving elements is so distributed along the length of the frame as to bring the product of the distances from the centre of gravity to the axes of the front and rear wheels to a substantial equality with the square of the radius of gyration of the vehicle as a whole about the centre of gravity. The constructional arrangements particularly described and claimed are substantially the same as comprised in Specification 373,234.

Abstract: 1535587 Mechanical interrupters SINGER CO 31 March 1976 [11 April 1975] 12863/76 Heading H1N A continuously driven interrupter having a manually settable ON/OFF ratio variable from 0 to 100% comprises a motor in space 14 driving a cam 18 which is moved axially against spring 20 when an axial projection thereon engages an axial projection on a disc 22 (settable by shaft 24), thus allowing follower nose 36 of lever 28 to drop off circumference 40, closing contacts 54, 56 and preventing return of cam 18. The projections move cam 18 further axially such that follower 36 drops off second peripheral surface 42 to close contacts 62, 64. This condition holds until a notch in cam 18, between surfaces 70 and 72, reaches follower 36 whereupon spring 20 restores cam 18 axially and sloping surface 72 lifts follower 36 back on to the circumference 40, opening both pairs of contacts. By providing the projection on settable disc 22 with a flat top extending over the angular extent of the notch between surfaces 70 and 72 it can be set to prevent restoration of cam 18 and give continuous closure of the contacts; while an arm (not shown) on disc 22 may be set to interfere with lever 28 and maintain the contacts continuously open.
