Patent FR-2278014-A1 (FR)
Title: Heavy duty friction clutch - has rotatable friction surfaces mechanically engaged by cam operated plunger
IPC: F16D67/02
Filed: 1974-07-08
Abstract: The clutch is a fluid-tight assembly connected to an engine flywheel and has a flanged hub carrying a friction disc on its rim, axially movable but non-rotatable w.r.t. the hub. A friction face on the flange is able to contact another face on the flange of a sleeve movable in the hub. These faces are engaged after the friction disc is disengaged from the rotatable clutch assembly. Disengagement is by an axially operating release plunger which pushes against a release lever to separate the friction disc. The sleeve carries a release bearing which is held against rotation along with the second friction surface. The housing shifts axially to move plunger and sleeve and engage the surfaces.

Title: Lifting mechanism safety device - screws into mechanism and has shoulder held against frame by drive
IPC: B66F1/08
Filed: 1974-08-30
Abstract: The lifting ram (8) engaging with the load is supported on a frame (1), and a support (6) is provided to hold the load at any desired height.

The part of the lifting mechanism concerned can be a screwed rod, and the support a driven but, with a shoulder bearing against the frame. The ram can comprise a ring-shaped cylinder in which ring-shaped piston works, the rod passing through the centre of both. The portion of the lifting mechanism not supported on the frame can be screwed along the rod by a drive when the safety device is engaged.

Title: Automatic dividing head for machine tool - has table driven by worm and air motor with piston actuated locators and hydropneumatic lock
IPC: B23Q16/06
Filed: 1975-06-13

Title: Hydrofoil craft supported by rotating discs - has drive shafts extended telescopically and raised and lowered by power cylinder
IPC: B63B1/30
Filed: 1976-05-13
Abstract: The hydrofoil craft has two or more pairs of discs (15) mounted on drive shafts extending sideways from the hull at an angle to the surface of the water. Each disc is rotated by a drive through its shaft, to assist the travel of the craft with the hull supported above water level. The drive shafts can slide telescopically inside guide sleeves through the hull, and each can be driven through a bevel gear drive by a drive unit at the centre. The guide sleeves are attached to curved sealing plates inside and outside the hull so that these plates can slide around the curved face of the hull to vary the angle of the drive shaft so as to raise and lower the discs. This sliding movement is caused by a power cylinder between the shafts, with a piston each end connected to a corresponding guide sleeve.

Title: Absorption refrigerator driven by solar energy - has generator constructed integrally with solar collector with interposed throttle
IPC: F25B27/00
Filed: 1976-12-08
Abstract: The solar energy collector (8) forms the outer layer of a two leaf heat exchanger (7, 8). The absorption refrigerator generator (3) is built integrally with this assembly behind the upper part of the collector. There is a throttle valve (14) in the connection between the collector (8) and the generator (3). Liquid strong in refrigerant, is drawn by a pump (1) from the absorber and passed through the collector (8) into the generator (3). The refrigerant is evaporated in the generator and discharged (4) to the cooling coils, while weak liquid drains through the inner leaf (7) of the heat exchanger to the absorber. The throttle valve (14) prevents premature evaporation of the refrigerant in the collector and the compact assembly provides direct heating to the generator.
