Title: Improvements in or relating to vacuum and compressed-air braking installations for rail vehicles
IPC: B60T13/60
Filed: 1961-09-07
Abstract: 954,316. Fluid-pressure brakes. KNORRBREMSE G.m.b.H. Sept. 7, 1961 [Sept. 10, 1960], No. 32200/61. Heading F2F. In a vacuum and compressed-air braking installation for rail vehicles having a train pipe 7 controlling a vacuum-controlled compressedair operated brake is by its pressure behaviour, and a main air pipe 25 associated with an indirect compressed-air brake (not shown), a valve device 23 is provided whereby pressure variations occurring in the train pipe are imposed in inverse proportion on the pressure behaviour of the main air pipe. By an indirect compressedair brake is meant a brake which is operated by a rise in the pressure in its brake cylinder when a fall in the main air pipe occurs. As shown, a branch pipe 3 connects a driver's valve 5 to a pump pipe 1. The vacuum train pipe 7 is provided with a branch pipe 9 which leads to a vacuum and compressed-air valve 11 to which is connected a vacuum reservoir 13, a compressed-air brake cylinder 15 and a compressed-air supply pipe 17. When the vacuum in the pipe 7 is at control value valve 11 vents the cylinder 15 and when there is a pressure increase in the pipe 7 the valve 11 supplies air to the cylinder 15 from the pipe 17. The valve device 23 transmits the pressure conditions occurring in the train pipe 7 to the main air pipe 25 of the compressed-air braking installation. When the brakes are applied air flows through the pipe 7 into the control chamber 21 and forces the piston 29 downwards, the valve 11 operating as indicated. The valve 47, 51 of the valve device 23 opens and vents the pipe 25 through longitudinal bore 45 and chamber 39 to atmosphere. As soon as a new equilibrium of forces is achieved at the piston system 29, 41 the valve 47, 51 closes. The pressure drop introduced into the air pipe 25 operates the indirect compressed-air brake. To release the brakes, a vacuum of control value is again introduced into the train pipe 17. The spring 35 therefore opens valve 51, 53 until control pressure is again fed into the air pipe 25 through the chambers 49, 43 from the compressed-air feed pipe 55 and the indirect compressed-air brake is released.

Abstract: 834,907. Jet propulsion nozzles. ROLLSROYCE Ltd. Oct. 15, 1957 [Oct. 23, 1956], No. 32344/56. Class 110 (3). [Also in Group XXXIII] A jet propulsion nozzle constructed so that the gas stream at the outlet is of annular form has means to supply, in some operating conditions, air internally of the gas stream whereby substantial mixing of the air and gas stream progresses from both the internal and external surfaces of the annular gas stream and, in other operating conditions, the supply of air is cut off. The jet pipe of a gas turbine jet propulsion engine comprises an outer cylindrical wall 20 and a centre body 21 between which is formed an annular exhaust passage 23. The centre body is supported from the wall 20 by two sets of struts 24, 25. The struts 25 are hollow and meet the outer wall 20 at a portion which is beyond the after end of the fairing 10. A shaped centre body 27 is telescopically mounted in the centre body 21. To provide a supersonic jet velocity the walls 21, 26, 27 may be shaped in accordance with Specification 668,344. The bullet 27 is actuated by the piston 28 of a pneumatic ram under the control of a valve 31. When the ram is collapsed as shown the bullet 27 is retracted in the centre body 21 so that the portion 27a of maximum diameter is upstream of the inner ends of the struts 25. Air from outside of the wall 20 is then conveyed through the struts to within the wall 21 and internally of the annular jet. When the ram is extended the bullet 27 is moved into a position in which the 27a cuts off this air supply. The nozzle may be combined with means for producing a reverse thrust for braking which may comprise clamshell type elements pivoted on the end of the jet pipe. When the reverse thrust means is operative exhaust gas may flow in part outwardly and forwardly through the passages in the struts 25 to produce the braking thrust.

A spring j is connected between the lever k and a lever i pivoted to the slidable core h of a solenoid g, whilst a pair of toggle links m is connected between the lever k and a fixed arm n. The links m are connected by a knuckle-joint of such form that when they are in the position shown in Figs. 1, 3, they cannot be collapsed by an upward pull exerted on the lever k. The lever i is connected to a known timing mechanism u through a link s and a crank t on the timer spindle v. A disc w secured pn the spindle v has a peg z co-operating with a part 2 rigid with one of the links m, and a notch x in the disc co-operates with a peg y on the lever k. In operation the solenoid g is energized to lift the core h and stretch the spring j, the right-hand end of the lever i being held stationary by the link s. Spring j then rotates the disc w through the lever i and timer u so that peg z strikes the part 2 to move the'toggle overcentre and permit the spring j to operate the bar e, the peg y entering the notch x to arrest the disc w. On de-energization of the solenoid the switch is restored to its initial condition by the spring j acting on the lever i, the latter striking the upper end of a link q connected to the lever k, a peg r on the arm n engaging a slot in the link q to guide the latter. The timer u is ineffective during the resetting action.
