Patent FR-2233211-A1 (FR)
Title: Brake rod for railway trucks - has mechanical separation between the two parts of the braking circuit to limit pressure
IPC: B61H15/00
Filed: 1974-06-11
Abstract: The brake governor has a member which extends beyond it and which, during braking, moves towards the projecting knob of a lever actuated by a cylinder. This connects an eyelet component of the governor to the lever. The projecting knob of the lever is mechanically separated from the governor. The stop for the governor is adjustable so that pressure is applied direct to the brake until the stop position is reached. After this point, further pressure is applied against the resilience of the governor.

Title: Suspensions transferred between closed systems - without loss of pressure or wastage using piston and valved cylinder
IPC: C02F11/121
Filed: 1974-07-23
Abstract: In continuously removing a quantity of a liquid or suspension from a closed system at a given pressure into another system at a different pressure the two systems are interconnected by a cylinder closed at its downstream end by a plug; after the liquid has entered the cylinder from the source system, a piston is introduced at that end and advanced through the cylinder, the plug at the other end being simultaneously removed to permit the liquid to flow into the second system. When transference is complete, the plug is replaced, the piston is withdrawn and the operation can be repeated. This procedure may be combined with simultaneous enrichment of the suspension or liquid; for this purpose, the wall of the cylinder is formed as a filter, the piston is advanced for a certain distance to expel liquid through this filter before the closure plug is opened; after this, the procedure is carried out as before. No direct communication between the systems, or equalisation of pressures, is necessary. No overflow or wastage of material takes place. The mechanics of the system are extremely simple.

Title: Piston shoe of a radial piston engine - has openings for improving flow, reducing losses and preventing overheating
IPC: F01B1/06
Filed: 1975-01-15
Abstract: The piston shoe of a radial piston engine is used for the reciprocating piston actuated by a rotor and this piston slides within a radial cylinder. The piston shoes have radial guiding surfaces, and are used in hydraulic or pneumatic compressor pumps, motors and drives. The performance of the engine is improved by correcting small errors in the hydrostatic support of the piston shoe, which ensures that efficiency is maintained at a very high level also at high power outputs, and losses are reduced so that the unit is not overheated. The sealing face of the pressurised fluid pockets (2) have openings in the bearing support faces of guides (6) of the piston shoes (7). These openings are arranged in the sliding faces and form openings in the piston shoe and parts.

Title: Automatic machine glues veneer strips to board edges - in three gluing operations and trimming operation
IPC: B27G11/00
Filed: 1976-04-08
Abstract: Instead of covering the rebated edge of a board only with a soft material, such as plastics which can be bent and fitted in one piece, wood veneers, can be applied by a machine which covers the rebated edge in three stages, using flat strips of veneer (9, 26, 35) applied separately. Each veneer is moved forward from its supply point, glued, guided to the surface of the moving board and pressed down by rollers (37) all under the control of microswitches which register the board's progress along the conveyor. In addition, rotary cutters, in the position of the rollers (37) operate between the gluing stations to trim the overlap from the edge of one veneer (9) so as to give a flat, unencumbered surface to which the following veneer (35) can be applied with overlap.
