Title: Improvements in or relating to gear changing or selecting mechanism for motor cycle and other gear-boxes
IPC: B62M25/04
Filed: 1932-03-29
Abstract: 381,853. Controlling change speed gearing. WHISTANCE, K. J., 86, Manor Road, Wednesbury, Staffordshire. March 29, 1932, No. 8955. [Class 80 (ii).] Relates to motor-cycle and other gear-change mechanism of the type in which step-by-step displacements are imparted to a change-arm d by a pedal b to which repeated oscillations in one direction or the other are given. The pedal b is formed with a disc, Figs. 2 and 3, pivoted on a pin b<1> mounted on a fixed member a. The disc carries a pin b<2>, the end of which is interposed between springs c, e<1> in the member a which bring the pedal back to its mean position after a displacement. Pawls g, g<1> are mounted on pins b<5> on the back of the disc and the tails thereof are connected by a spring h passing over the pin b<2>. The pawls engage two sets of oppositely-directed ratchet teeth f, f<2> on a ring d2 integral with the change-arm d, the ring being mounted on a boss a<1>. The boss is eccentric to the pin b<1> so that when the pedal b is depressed as shown in Fig. 4, one pawl g<1> in engagement with one of the notches f<2> is turned anticlockwise about its pivot b<5> thus tensioning the spring hand holding the tail of the other pawl g against a stop b<6> on the disc. The pawl g thus held moves in a path x away from its ratchets, thereby eliminating, any possibility of the change-arm d being returned to its original position on the return stroke of the pedal.

Title: Improvements in or relating to the recording of sound photographically on strip records
IPC: G11B7/00
Filed: 1931-03-31
Abstract: 381,181. Electrostatic meters and accessory apparatus. CANTLAY, D. F., 87, Wardour Street, London. March 31, 1931, Nos. 9715 and 9716. [Class 37.] Sound is recorded by the use of an electrostatic light valve one electrode of which is made of a thin strip of foil stretched to have a high natural resonant frequency and located near to the other electrode, the strip of foil carrying a shutter which controls a beam of light directed upon a photographic film. As shown by Fig. 1, a block of insulating material 2 mounted on a metal carrier 1 carries a fixed electrode 3. A strip of metal foil 4, acting as the other electrode, is fixed by a clamping plate 5 to the carrier 1 and at its other end is connected by a clamp 7 to a spring 6 by which tension is applied to the strip 4. The spring 6 is secured to a screw 8 which passes loosely through the carrier 1 and a nut 9 acting against a boss on the carrier allows for adjustment of the spring tension. The strip 4 passes over two glass bridges 10 and in contact with it are two rubber dampers 11 which are pressed towards the bridges 10 by springs 12. The strip 4 carries at its centre a shutter 13 which controls the recording light beam. For producing records of variable density a rectangular shutter is used. For recording variable width records a shutter 13 having an inclined edge, Fig. 5, is used or, alternatively, the shutter may have a double inclined edge, Fig. 6, or a toothed edge, Fig. 7. Fig. 2 shows an alternative construction of apparatus wherein two strips of foil 3a, 4 are clamped to an insulating block 2, and tension is applied to each by a clamp 7, spring 6, screw 8, and nut 9. The lower strip 3a rests on glass strips 10 and rubber dampers 11 are located between the two strips 3a, 4. In a further modification, Fig. 3, there are two fixed electrodes 3 each carried bv a block of insulating material 2 and between them is stretched a third vibratory electrode 4, made of a strip of foil, which carries the shutter 13. In use, varying voltages corresponding to the sound to be recorded are applied across the electrodes to cause varying forces of electrostatic attraction between them. The shutter so vibrated causes obturation of the light beam to effect a record of the sound on a moving photographic film.
