Title: Low energy hydraulic actuator
Inventor: RICHESON WILLIAM E
IPC: F01L9/20
Filed: 1991-04-17
Abstract: PHA 40.594                                       03.04.1991 ABSTRACT: Low energy hydraulic actuator.     An electronically controllable hydraulically powered asymmetrical valve actuating mechanism for use in an internal combustion engine of the type having engine intake and exhaust valves with elongated valve stems is disclosed. The actuator is a bistable electronically controlled hydraulically powered transducer having an armature including a power piston which is reciprocable between first and second positions along with a hydraulic arrangement for powering the armature from a first (engine valve closed) position to a second position. A bistable control valve is operable in one of its stable states to supply high pressure hydraulic fluid to one face of the piston to power the armature and in the other of its stable states to relieve the high pressure fluid from the piston. The mechanism has a compressible resilient arrangement such as a coil spring or a chamber in which air is compressed during motion of the armature from the first position to the second position. This compression of the air not only slows armature motion as it nears the second position, but also provides a potential energy store for powering the armature back to its initial position. The control valve remains in said one stable state to temporarily prevent reversal of armature motion when the motion of the armature has slowed to a stop, the control valve returning to the other of its stable states on command to allow the spring or air compressed in the chamber to return the armature to the first position.

Abstract: Method for the warp printing of a design on a machine for the production of warp fabric, characterised in that it involves: 
 
  - between the exit of the beam (2), but before the inserting or tying member, bringing into the vicinity of the lap of warp yarns (1) a transfer paper (16) carrying a dye design capable of being transferred onto the yarns under the effect of heat; 
  - then, causing this transfer paper (16) to run in a speed ratio with the speed of advance of the lap of warp yarns (1); 
  - then, still continuously, pressing down permanently this transfer paper (16) running against the lap of warp yarns which likewise runs in this ratio with the paper, taking care to direct the sheet of transfer paper carrying the design towards the lap of warp yarns, and simultaneously transferring this design onto the yarns under the continuous effect of this pressure and of dry heat; 
  - and finally, separately receiving the printed fabric obtained after insertion and the transfer paper, the design of which has been at least partially transferred onto the lap of warp yarns (1).
