Title: Improvements in or relating to hydraulic transmission systems, in particularl for the control of the brakes of an automotive vehicle
IPC: B60T13/16
Filed: 1934-04-13
Abstract: 436,949. Hydraulic transmission of power. RIBIS, G. P. G., 158, Boulevard PÚreire, Paris. April 13, 1934, No. 11258. Convention date, April 14, 1933. [Class 69 (ii)] [See also Group XXXIV] An hydraulic brake comprises an auxiliary piston 101 adapted to exert additional pressure on the liquid in the casing 1 and thus on the pistons 191, 19<2> transmitting this pressure to the brakes, after a preliminary pressure has been exerted by the main piston 4<a>, the pistons being operated by independent means and being mounted with the pistons 19<1>, 19<2> in a single casing 1 with the interposition of a single liquid mass between these members. This additional pressure may be exerted manually or by a pump. In Fig. 2 two pistons are shown connected to the brake by balance levers 152<1>, 152<2>. In Fig. 2 is shown an arrangement for preventing piston 101 exerting backward pressure on piston 4<a>. This comprises an additional piston 155 sliding on piston rod 4 and pressed by a spring 156 against a shoulder on the rod. The pistons 4<a>, 155 force liquid through orifices 157<1> and 157<2> and piston 155 finally closes orifices 157<2> and rests on seating 157. When auxiliary piston 101 is operated the pressure it develops acts in opposite directions on pistons 4<a>, 155 which balances the effort on the rod 4. There is a direct connection 150 for operating the brakes manually. In a further modification the auxiliary pressure is exerted by a pump normally circulating through a circuit including the supply tank, controlled by a valve adapted to close the circuit and open the pump to the piston 101 and a relief valve, the piston 101 transmitting the effort. In a modification the effort is transmitted directly through orifices 23<3>, Fig. 7, the piston 101 bearing against a spring 170 which flexes during the additional braking and thus limits the braking effort.

Patent GB-438568-A (GB)
Title: Improvements in or relating to radio receiving systems
IPC: G01S1/02
Filed: 1935-04-12
Abstract: 438,568. Wireless signalling. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. April 12, 1935, Nos. 11443, 11444, and 11445. Convention dates, April 18, 1934 and June 7, 1934. [Class 40 (v)] Relates to sys tems particularly for direction finding in which the reflected space - wave component of a signal is eliminated at the receiver so that the indication is given wholly by the ground wave. According to the invention the anode voltage on the output valve R, Figs. 1 and 3, is discharged by the groundwave impulse J, through a condenser C which then recharges slowly through a resistance W in accordance with the dotted-line curve S, so that the valve is nonconductive to the subsequent reflected impulses D. In order further to lessen the chance of interference from "reflected" signals, each signal element is split up into individual impulses with intervening spaces. For telegraphic signalling the valve is similarly made responsive only to the square-topped voltage impulse B, Fig. 3, corresponding to the time AT, the subsequent " irregularities " R due to the space-wave component being ineffective. The signals are recorded on an impulse voltmeter. In a directive A-N system in which the frame aerial is periodically reversed in polarity, a reversing switch is used to short-circuit the condenser C during the change-over, so as to ensure that it is fully discharged prior to receiving the next signal. Specification 381,856 is referred to.

IPC: G07F11/08
Filed: 1954-04-22
Abstract: 768,843. Coin-freed vending apparatus. VENDO CO. April 22, 1954, No. 11620/54. Class 27. A vending machine, which is preferably coin-freed, has a refrigerated cabinet with several chambers 12 in each of which cylindrical articles, such as bottles 14, are stored in two staggered columns with the lowermost article engaging a reciprocable freely-rotatable roller 16, and, by partial rotations of a shaft 34 having screwthreaded portions 40 engaged by a follower block 46 on each roller, the rollers are moved in steps across the bottom of the chambers from a position supporting one column to a position supporting the other column; each roller is a step in advance of the succeeding roller so that they reach in turn the " release " position indicated at the right-hand side of the Figures and allow the bottles to fall into one or other of a pair of delivery shoots 18. The shaft 34 is rotated in one direction by a chain or other drive 38 from a motor 36 and each follower block completes its movement from left to right along one thread of the portion 40 during one revolution of the shaft and returns along an intersecting thread of opposite hand-during the next revolution. The beginnings of the threads in one portion 40 are spaced at 120 degrees from the beginnings of the threads in the next portion 40 and each thread increases in pitch towards the " release " end so that the final "release" movement is quicker and greater than the movements when a roller is in its bottle-supporting positions. The rollers are supported by wheels 24 running in tracks 26, and, to ensure that they remain parallel during reciprocation, gears 28 on their ends engage racks 30. Specification 718,726 is referred to.
