Title: Clutch control valve
Inventor: JENNINS WILLIAM STUART
IPC: F16D48/06
Filed: 1989-06-07
Abstract: An electrically controlled clutch control valve which provides both hydraulic flow and hydraulic pressure control to the clutch cylinder comprises a valve body 11 containing a spool 12 maintained in contact with the drive pin 13 of the electrical actuator 14 by a spring 20. Port 16 is in communication with the clutch cylinder and when an increase in pressure is required, spool 12 is pushed by actuator 14 to allow additional fluid to flow from the pump port 17. When pressure is higher than required, the spool is moved to allow port 16 to communicate with the tank port 18. To control flow, positional feedback with respect to the spool is provided by a displacement detector 19 and the spool is moved to known positions (FIGS 3 and 4). When a position of maximum pressure is reached a further displacement detector on the clutch cylinder instructs the control circuit not to increase the pressure further. Gear changing is permitted when the ports 17, 18 are isolated from port 16 and the clutch is disengaged. <IMAGE>

Title: Automatic railway platform barrier
Inventor: SHADBOLT JEREMY RALPH
IPC: B61B1/02
Filed: 1990-05-14
Abstract: A barrier (5) has a moulded rubber wall of tapered cross-section, widest at its base and narrowest at its top when it is in the upright position and is hinged along its lower edge to a railway platform. The barrier separates waiting passengers on the platform from the potential dangers of the permanent way (railway track well). The barrier extends for the full length of the platform and is depressed along its length by the action of an approaching train. The forward motion of the train transfers a turning force to the barrier via bearing assemblies (3) fitted to the train and depresses the barrier into the permanent way. When the train departs the barrier is automatically restored. The barrier is flexible and provides a barrier regardless of the length of the train. Where it has been depressed it is invisible to waiting passengers and obstructs them in no way. <IMAGE>
