Abstract: 821,275. Brake beams. BUFFALO BRAKE BEAM CO. April 26, 1957, No. 13400/57. Class 103 (1). [Also in Group XXV] A wear-plate 35 and a spring connected thereto, are received in a brake beam guide recess 30 of a railway car bogie sideframe 10 with the spring 55 engaging the brake beam 15 to co-operate with a spring at the other end of the beam to centre the brake beam laterally with respect to the side frames on release of the brakes. The brake beam 15, Fig. 2, comprising a cambered compression member 17 and a V-shaped tension member 18 jointed at their ends and with a strut connecting the apex of member 18 to the middle of member 17, carries brake heads 20 and shoes 16, the ends 45 of beam 15 being slightly curved and provided with hard spring metal, U-shaped wear-plates 48. The ends 45 slide in upwardly-directed, inwardly-opening, recesses 30 cast in frame member 10 having upper and lower walls 31, 32 reinforced by brackets 33, 33a, and an end wall 34, the other end remaining open for the removal of the brake beam as necessary; the recesses are not machined so hardened spring wear-plates 35 are provided for accurate bearing-surfaces, the plates 35 being channel-shaped with diverging sides 37 and a back wall 36, Fig. 7, and held in the recesses 30 by protuberances 42 on sides 37 engaging corresponding holes 43 in recess walls 31, 32; due to the diverging sides 37 the protuberances 42 are held in holes 43 by the spring in the plate 35.

Abstract: 1,119,009. Telegraphy. CREED & CO. Ltd. 28 March, 1967, No. 13951/67. Heading H4P. A telegraph apparatus for simplex operation comprises a shift register which receives serial code combinations when the apparatus is receiving and, when the apparatus is transmitting, receives parallel combinations the elements of which are shifted out to line. The state of the line is sampled during each element and the sample inserted in the stage of the register left vacant due to the shifting. In the embodiment described, when the keyboard 52 gives a parallel signal to a register comprising BS1- BS5 a clock 54 is started. The clock feeds bitrate pulses to the logic circuit shown which locks the keyboard, blocks the receive line R and sets BS8 to send a Start bit on line S. Shift pulses are applied to the register and the line S is sampled at the mid-bit points by gate 28, the samples being inserted in BS1. When a complete character has been sent a Stop bit is added and gate 43 is enabled so passing the contents of the register, which is the combination actually transmitted, to monitor-printer 53. The keyboard is unblocked. If, after a time set by delay 46, no further key has been operated the receive line is unblocked. The Start bit of a received combination starts clock 54 and the bits are mid-bit sampled at 28 as before, the samples passing to the register which is subsequently read out to the printer during the Stop bit.

Delivery and suction accumulators 9 and 16 are connected to the outlet 8 and inlet 19 of an hydraulically-actuated piston pump 1, 2 to provide continuity of supply and delivery. The accumulator pistons 10 and 17 are biased by the supply and exhaust pressure, respectively, of the actuating liquid, e.g. oil, and by springs 11 and 18. The supply and exhaust of actuating liquid to the pump 1, 2 is controlled electrically by piston operated contacts 3, 4 actuating valve 5. In a further embodiment, Fig. 2 (not shown), a pump (21) having a pair of linked pistons (22, 23) is connected to delivery and suction accumulators (42 and 42) having connected pistons (38 and 39) biased by a common spring (44). The linked pistons (22, 23) operate spool valves (27 and 28) controlling the supply and exhaust of actuating liquid and the inlets and outlets from the piston cylinders are connected in parallel. In another embodiment, Fig. 3 (not shown), two pairs of diaphragms (101) are actuated through bodies of liquid by hydraulic motors (102) having pairs of linked pistons. The inlets and outlets of the diaphragm pumps are connected in parallel and suction and delivery accumulators are provided for each pair of pumps. The accumulators are biased by the supply and exhaust pressures of the motor actuating liquid and by adjustable pneumatic pressure. The actuating liquid for the motors (102) may be supplied in parallel or in series. With the motors operating in series liquid is exhausted from one motor and supplied to the second and the pressure drop from inlet to exhaust in the motors is the same for each motor. With this arrangement the inlet pressure for the first motor in series is substantially twice that for the second and the flow of actuating liquid is substantially half that required for parallel operation. The sides of accumulators operating on pumped medium are separated therefrom by means diaphragms acting through bodies of trapped liquid. To reduce hammer in the valves controlling the supply and exhaust of actuating liquid they may be operated slowly to give extended reversal periods.
