Title: An improved switch for controlling the electrical circuits of motor cycles and other road vehicles
IPC: B62J6/16
Filed: 1954-02-19
Abstract: 755,122. Mechanical switches without quick action; hand actuating devices for switches; press-button retractive switches. FALCONER, R. S. Feb. 14, 1955 [Feb. 19, 1954], No. 4897/54. Class 38(5) A switch adapted to be mounted on the handle bar of a motor cycle or similar vehicle has a casing 3 mounted on the handle bar 1 through which leads 5 pass and which contains a fixed switch body 7 carrying contacts 27 and 30, insulating discs 8, 9, and 11, and a contact ring 10 rotatably mounted on a fixed insulating disc 22 and adapted with projections 26 and 32 to engage the contacts 27 and 30. A handle grip 3 rotatably mounted on the handle bar has an end flange plate 15 and is kept in position by a spring 17 located in a groove 18. Members 8, 9, 22, and 11 are fixed to the member 7 by screws 12. The ring 10 is rotated by means of a lug 21 engaging a notch 20 in the flange 15 and is located in any of several positions by a spring-loaded detent 23 in the disc 22 engaging notches 24, whereupon various combinations of contacts 27 and 30 are bridged. The disc 11 has a cut-away sector 25 which limits the movement of the ring 10. A press button 6 in the casing controls the horn circuit. The discs 8, 9, and 22 may be integral with the member 7. Instead of a handle grip, control of the switch may be effected by finger movement on an extension of the lug 21 passing through the plate 11.

Title: Improvements in tuning wireless circuits
IPC: H03J1/10
Filed: 1926-02-20
Abstract: 271,163. Sherrin, J. Vaughan-. Feb. 20, 1926. Condensers. - Apparatus for tuning two or more valves or other radio circuits with one control comprises screw-adjusted, variable-ratio gearing for simultaneously varying a number of condensers. Three rotatable-vane condensers may be controlled simultaneously by a cord, chain, or wire G, Fig. 3, passing around pulleys A, B, C on the shafts L of the rotatable vanes, the pulleys being expansible by screw devices to vary the gearing. The cord G is provided with right- and left-handed screw devices E and with a tensioning spring H to allow adjustment of the relative positions of the pulleys. The shafts L are out of line and the cord G passes completely round the pulley B and half-way round the pulleys A, C. pins screws or cyelets D preventing slipping. Alternatively, pulleys on the shafts of coaxial condensers are similarly connected to pulleys on a parallel common control shaft, some or all of the pulleys being expansible. The expansible pulleys in these arrangements may comprise rubber or other yielding material F<1>, Fig. 6, carrying a split, V-sactioned, metal ring E<1> and expanded by compression between flanges A<1> adjusted by a lateral screw-flange C'. To compensate for irregularities in the capacities, the pulleys may be expanded unequally on different radii by additional screws drawing the flanges A<1> together. In a modification, the pulleys may comprise starshaped stampings the arms of which are intercalated to form a grooved rim expanded by screwadjustment of the stampings towards each other and contracted on the reverse adjustment by the pressure of the cord or a spring. In another modification, the pulleys are replaced by a semicircular grooved bow expansible by a right- and left-handed adjusting screw the end of which abuts against a slide connected to the centre of the bow and the threads of which engage a block on the supporting shaft and a nut carrying pivoted links connected to the ends of the bow. The lengths of the links can be adjusted individually. In a further modification, a number of condensers A<2>, Fig. 4, with parallel shafts L<2> carrying friction discs B<2> are simultaneously controlled from a shaft C<2> through friction discs E<2> adjustable radially of the discs B<2> by screw flanges D<2>. The stators of several condensers controlled by these gearings may be axially rotatable for initial adjustment and locked in adjusted position, for example, by a screw on the statar frame passing through a slot in a fixed bracket, the stators being initially adjusted directly or through gearing whilst the rotors are kept stationary by the variable gearing. The Provisional Specification describes also pulleys expanded by lever adjustments, condensers with vernier plates controlled from a countershaft through variable gearing similarly to the main plates, and the application of the gearing to the control of condensers in one-valve or crystal sets and to the separate control of aerial tuning and intervalve couplings in multi-valve sets.

Title: Improvements in or relating to resistance weld control method and apparatus
IPC: B23K11/24
Filed: 1945-02-27
Abstract: 606,958. Control systems for resistance welding. BUDD MANUFACTURING CO., E. G. Feb. 27, 1945, No. 4904. Convention date, Feb. 28, 1944. [Class 38 (iv)] In resistance welding, the voltage drop occurring at the weld upon its completion is employed to actuate control means in the timer to interrupt the welding circuit or to furnish an indication for the purpose of a manual adjustment of the control. As shown in Fig. 1, the control valves 27, 28 for ignitrons 18, 19 supplying welding current are associated with timing means 25 which may be manually adjusted and automatically controlled to terminate the welding current. The welding electrodes 15, 16 may be connected to an oscilloscope 41 to demonstrate the aforesaid fall in voltage, whereby adjustment may be made to the timer to cause the supply to cease after a weld time not substantially exceeding that required for a weld. The electrodes may also be connected to a circuit 46 which translates the percentage drop in voltage on weld completion into an impulse which is fed through an amplifier 42, a control unit 43 effecting the required adjustment of the timer; the impulse may also be supplied to a device 48 duplicating the signal 41 or giving any other audible or visible signal of weld completion. Two circuits which may serve as the circuit 46 are described, one depending upon the potential of a condenser charged from the welding electrodes and the other upon the relation between welding current and the voltage across the welding electrodes. The electrode voltage may be taken from auxiliary electrodes adjacent to the welding electrodes and in contact with the work.

Title: Improvements in duplicating machines
IPC: B41L7/08
Filed: 1943-03-31
Abstract: 565,787. Damping sheets in duplicating machines. FORD; F. R. March 31, 1943, No. 5158. [Class 95] In duplicating machines of the type in which an original sheet bearing a mirror copy on the back is stretched around a cylinder 12, and in which moistened sheets are fed between the cylinder and a pressure roller 14, the copy sheets are damped by a moistening device which includes a rigid plate 18, carrying a feed wick 16, and a readily detachable plate 25, on which a moistening pad 26 is mounted so that one marginal portion of the pad projects beyond the edge of the plate and is thus exposed, a screw 31 (or equivalent means) being provided for drawing the two plates 18 and 25 towards each other, at a position remote from the exposed portion of the pad and acting at right angles to the planes of the plates. Light pressure between wick and pad is produced by tightening the screw which is grooved to engage slots and so remain attached firmly to the upper plate although it may have been disconnected from the lower plate. The copy sheets are pressed into contact with the moistening pad 26 by means of a bar 35, carried by a pair of bell-crank levers 36, pivoted at 37. Cams 41 on the ends of the cylinder 12 engage rollers 40 and so allow the bar 35 to be moved away from the moistening pad. A shorter second arm 42 of the levers is connected by light tension springs 43 to an adjustable screw 44. Specification 550,664 is referred to.
