Title: Gas turbine engine rotor assembly
Inventor: TOUGH EDWARD DENNIS
IPC: B23P15/00
Filed: 1981-11-13
Abstract: A method of assembling a gas turbine engine rotor comprises locating a bladed ring (10) on the periphery of a disc (13) and subjecting the assembly to hot isostatic pressing so as to achieve diffusion bonding across the interface between them. A ring-shaped plate member (15) is laid over each of the joint lines between the bladed ring (10) and the disc (13) and sealed in place with a high melting point sealant (18) prior to hot isostatic pressing. During hot isostatic pressing, diffusion bonding also occurs between the plate members (15) and the bladed ring (10) and disc (13). This diffusion bonding of the plate members (15) may be easily inspected by ultrasonic means and provides a ready indication of the effectiveness of the degree of diffusion bonding across the interface between the bladed ring (10) and the disc (13). <IMAGE>

Patent GB-2093938-A (GB)
Title: Quick take-up and release of brakes
IPC: B60T13/66
Filed: 1982-02-23
Abstract: Air pressure in a brake pipe BP of a railway vehicle braking system varies between a maximum P1 corresponding to "run" condition with brakes fully released and a minimum pressure P2 corresponding to "full service" application. Between P1 and P2 is a predetermined brake pipe pressure P3 at which the brakes are at "initial application". As the brake pipe pressure drops from P3 to P2 the brakes are progressively increasingly applied. The brake pipe pressure is controlled by a known transmission valve 166 so that the brake pipe pressure equals the pressure in conduit 64. The pressure in conduit 64 is controlled by operation of a joystick to open or close brake application valve 22 or brake release valve 20. In control valve 74 chamber 70 is supplied with air at pressure P1 via conduit 34. Opening release valve 22 at "run" condition drops the pressure in chamber 78 below P1 to a predetermined value P4 between P1 and P3. This causes diaphragm 76 to move down lowering the spindle 82 to bring relatively large control reservoir 160 at pressure P1 into communication with relatively small minimum reduction reservoir 154 at atmospheric pressure. There is a sudden and automatic equalisation of the reservoir pressures by a drop to pressure P3. Since this pressure is on conduit 64 the brake pipe pressure rapidly drops to P3, the initial application pressure. If application valve 22 is held open the pressure in conduit 64 drops to minimum P2 by air escape through choke 52. The air pressure in conduit 64 is increased to release the brakes by supplying air pressure to the conduit through open release valve 20. When air pressure in chamber 78 rises to a predetermined value P5 between P3 and P4 the spindle 82 is lifted suddenly by the effort of springs 84 and 150 causing the chamber 78 to communicate with chamber 70 via conduit 110, poppet valve 102, 108 and bore 92. This causes a rapid rise in the pressure in chamber 78 and conduit 64 from P5 to P1 and a corresponding increase in brake pipe pressure. <IMAGE>
