Patent FR-2387395-A1 (FR)
IPC: F15B13/01
Filed: 1978-02-21
Abstract: The device comprises an adjustable main restrictor (8) connected in parallel with a non-return bypass valve (7). This measure is intended to prevent vibrations of the entire system during the control of speed independently of load on a double-acting pressure-flow consumer (4) subjected to a pulling load. To achieve a high control performance and low-inertia work, an inflow-side measuring restrictor (17) is arranged in one connection line (2) of the pressure-flow consumer (4), and an outflow-side measuring restrictor (22) is arranged in a branch line (23) leading from the other connection line (3) to the adjustable main restrictor (8). The two measuring restrictors are connected to each other via a connecting restrictor (21). During braking operation, the larger circular area (36) of a stepped piston (12) spring-loaded in the closing direction of the main restrictor is acted upon in the opening direction by the inflow pressure (Po) of the device, whereas one sectional area (37), in the opposite direction to the larger circular area (36), is acted upon in the closing direction by the consumer-side inflow pressure prevailing behind the inflow-side measuring restrictor, and the other sectional area (38) is acted upon in the closing direction by the outflow pressure arising in front of the outflow-side measuring restrictor. As a result of its high control performance through rapid response, the device is especially suitable for lifting and travelling drives of self-propelled machines and for ship winch drives.

Title: Turbocompressor shaft seal with flexible diaphragm - which blocks oil path from bearing housing to compressor if vacuum occurs in compressor
Inventor: SILVEY NORMAN GEORGE
IPC: F01D25/18
Filed: 1978-06-22
Abstract: The seal at the compressor end of the turbocompressor shaft (24) has a flexible diaphragm with a central hole. The periphery of the diaphragm is fixed w.r.t. the bearing housing. A bush (80) carried by the shaft has an annular face which abuts against a fixed annular face of the bearing housing. A gap is formed in the radial direction between the bush and the housing. This gap is bridge by the diaphragm. Gas that normally leaks from the compressor draws the diaphragm away from the annular face of the bearing housing. If a vacuum occurs in the compressor, the diaphragm clings to the face of the housing and prevents lubrication oil from passing into the compressor housing from the bearing housing.

Title: Prestressed tubular frame for window shutter - uses tie to correct flexibility obtained by using obtusely angled bi-spigot corner connectors
IPC: E06B9/04
Filed: 1978-07-06
Abstract: The prestressed frame may be used on window shutters. It is fabricated from hollow extruded metal sections, and uses screws fixed 'L' shaped double spigot pieces to fix the corners. The spigot pieces subtend an angle (a) of nominally greater or less than 90 deg. The posts of a rectangular frame are thus assembled with an initial prechamber. The camber is obtained by fixing the posts in a state of flexure, the posts both deflecting in towards the centre of the frame or both deflecting outward. At least one intermediate rail is fixed between the posts acting in tension or compression, and acting to correct the precamber. The spigot pieces may subtend an angle of between 90 and 95 deg., pref. 92 deg., and is fixed by self-tapping screws through bores and split sleeve formations in the respective members.

Title: Safety circuit relay contact maintenance circuit - passes periodically high current through contacts to break down oxidation layer
Inventor: MORIN MAURICE
IPC: H03K3/57
Filed: 1978-07-31
Abstract: The circuit ensures that the contacts of a circuit breaker in safety equipment remain in a serviceable state during periods of time when oxidation or general poisoning of such contacts due to ageing in polluted atmospheres occurs. The contacts of such switches normally carry low currents at low voltages, oxidation being sufficient to cause voltages drops sufficient to trigger alarm systems. Maintenance of good conductivity of such contacts is by applying a comparatively high voltage (about 50 V) for a short period (about 0.4mS) which breaks down the resistance layer caused by oxidation etc. Short pulses are generated once every three seconds by a transistor circuit controlling the charging time of a capacitor which then provides the periodic pulse into the contact circuit as part of its discharge loop by a second transistor.

Patent FR-2447445-A1 (FR)
IPC: E05F3/04
Filed: 1979-01-25
Abstract: The invention concerns a folding door of the kind having a primary panel pivoted about one axis on a frame, and a secondary panel articulated with respect to the primary panel and engaging a slide guide which is perpendicular to the pivotal axis of the primary panel. According to the invention, the two panels are articulated by links pivotally connected to each of the primary and secondary panels at second and third axes respectively, and the secondary panel engages the slide guide at a fourth axis located at an intermediate point along the panel, all the four axes being disposed centrally of the thickness of the panels; furthermore, the distance between the second and third axes is equal to the thickness of the panels, and the distance between the third and fourth axes is the same as between the first and second axes. With this construction, the door will open in a substantially smaller space than a conventional door and in addition it can be opened by a simple pushing action. The door is thus suitable for use by handicapped persons in e.g. hospitals and community homes.
