Title: Improved circuit arrangements for transmitting impulses in telephone systems
IPC: H04Q1/36
Filed: 1932-12-29
Abstract: 412,592. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. Dec. 29, 1932, No. 36813. Convention date, Dec. 29, 1931. [Class 40 (iv).] To ensure full energizations of a distant line relay B during impulsing over a loop circuit, an inductive aiding pulse is sent over the loop each time it is closed. The invention may be applied to impulse transmission from a registercontroller. When the incoming selector is seized over junction FL, closure of contact K1 completes the loop circuit for relay B over the upper winding of a relay A at the outgoing end of the loop, contact K2 being closed to initiate impulse transmission by C. Each time C closes the loop, it opens the lower winding of A which induces a pulse in the upper winding in a direction to assist the operation of B. It is arranged that K4 opens at the same time as or immediately after the closure of K3. The inductive effect may be improved by shunting the lower winding of A by a condenser, or an inductance in series with a resistance, and this winding may have an adjustable resistance in series. Inductances may also be inserted in the line at the incoming selector.

[Also in Division G3] The movement of a manually-operated speed control lever 16 of a centrifugal governor for controlling the injection of fuel into an I.C. engine is assisted or opposed by a first spring unit 1 which comprises two metal springs 3, 4 located between a plate 5, which bears against the fuel injector, and a displaceable plate 6 which varies the force exerted on the plate 5 and a second spring unit 7 which opposes movement of the displaceable plate 6 with a force which increases and decreases as the force of the first spring unit increases and decreases the difference between the forces of the two units being less than the maximum force of the first unit 1. In this way the force of the first spring unit 1 can be increased by using a manual control force which is less than the maximum force of the first spring unit. The plate 6 carries a piston 8 with cam surfaces 9 and a rod 14 which slides in a guide sleeve 15 in a fixed housing 12. A pair of opposed leaf springs 11, secured to the housing 12, carry rollers 13 at their free ends which engage the cam surfaces 9. When the springs 3, 4 are not compressed the leaf springs 11 transfer no component of force in the direction of movement of the plate 6. When it is desired to increase the force exerted by the first spring unit the control lever 16 is actuated to move the rod 8 so that the plate 6 moves to compress the springs 3, 4 and the rollers 13 move along the cam surfaces 9 so that the springs 11 exert an axial force which backs up the movement of the plate 6. Each spring unit 1 may be constructed to have a linear force-displacement characteristic. Specification 813,939 is referred to.

Abstract: 1477866 Pedal-crank driving mechanism FT DOMES 3 Sept 1975 [4 Sept 1974] 38623/74 Heading B7E [Also in Division F2] A pedal assembly for attachment to a crank arm 3 of a bicycle or other pedal driven device comprises a spindle 1, a disc 14 mounted eccentrically on the spindle, a pedal 27 having a slot which accommodates the spindle and enables the pedal and spindle to slide relative to another perpendicularly of the spindle, and guide means connecting the periphery of the disc with the pedal. The disc and spindle are fixed in use to the crank arm 3 such that their axes are parallel to the rotational axis of the crank arm and the guide means then act to guide the pedal in an elliptical path as the crank arm rotates on application of foot pressure to the pedal. In the illustrated embodiment the disc 1 has an annular band 19 rotatably mounted on its outer periphery by means of ball bearings 20, the band having a radial projection 38 bolted to a flattened end of a rod 32 rotatably mounted to a side of the pedal 27 by means of members 33. In operation, Fig. 5, the spindle 1 will be disposed centrally of the pedal at the top and bottom dead centre positions I and III of the crank arm 3. However when the crank arm and spindle are caused to rotate from either of these positions the pedal and spindle slide relative to one another, as shown at positions II and IV because of the connection between the band 19 and the pedal. In this way the pedal is caused to follow an elliptical path as the arm 3 rotates through 360‹. The pedal is of rectangular hollow construction, being open ended to provide the slot, and is mounted on the spindle through the intermediary of a tube 4 rotatably mounted on the spindle by means of ball bearings 5, 6. A peripheral part 23 of the disc 14 may be removable to enable insertion or removal of the ball bearings 20.
