Title: Load raising and lowering device - has locking plate pivoted to body to close gap between fixed and movable jaws
IPC: B66D5/16
Filed: 1975-03-21
Abstract: To fit the attachment for raising a load, the locking plate (3) is pivoted (7) on the body (1) to close the passage between the fixed jaw (9) and the moving jaw (12). A shackle (15) locks the rear plate (17) to the arm (13). The load is suspended from another shackle (4) on the body (1). When a pull (F1) is applied to the first shackle (15), the locking force between fixed and mobile jaws is released and load raised. Releiving the upward force again brakes the cord. To lower a load, the top levers are placed in the opposite direction and the cord passes through similar to a pulley block.

Title: Safety valve control in depressurised cistern - employs reserve of depressurisation to prevent valve hammer effect
IPC: G05D16/06
Filed: 1976-01-12
Abstract: A safety valve for a cistern under depressurisation is carried by a membrane which moves under depressurisation to cause the valve to open. A reserve of depressurisation enables a stable balanced position to be attained without hammer effect. A safety valve (5) is carried by a membrane (6) which forms a small chamber (7) with a channel (8) to the exterior. The other face of the membrane forms a second chamber (9) containing a return spring (10) and a channel (13) to the exterior. a valve enables this chamber to communicate with a third chamber (14) with a diaphragm (15) carrying a piston (16) which is moved to open the valve (12) when depressurisation increases. This causes the safety valve (5) to open.
Patent FR-2339143-A1 (FR)
Title: Water heating system utilising solar radiation energy - uses earth as thermal core with several parallel vertical holes
IPC: F28D20/00
Filed: 1976-01-26
Abstract: Several vertical holes are drilled into the earth a few metres apart from each other over an area sufficient to form a thermal core. The area is as nearly square as possible and the depth of the holes is approximately half the mean of the sides. The bore of each hole is made watertight by a rubber ring held in place by suitable studs. Water heated in a solar energy absorber is passed into a tube in the centre of each hole and rises up the outside of the tube after heating the surrounding earth. The arrangement and layout of the holes enables a comparatively small block of earth to store sufficient heat from summer to winter for domestic purposes.

Title: Gallium arsenide and phosphide prodn. from elements - by grinding and tempering below sublimation temp
IPC: C01B25/08
Filed: 1976-02-13
Abstract: Prodn. of arsenides or phosphides of main Gp. III elements, esp. Ga, at below the sublimation point of As or red P, is carried out by grinding and tempering a stoichiometric mixt. of the elements forming the cpd. concerned. Polycrystalline almost stoichiometric AIIIBV semiconductor material can be produced economically in open, i.e. not sealed or evacuated, reactors, even in kg amts. Pref. grinding and tempering are carried out repeatedly (pref. 3-8 times) in consecutive separate stages. The first tempering is at 200-400 degrees C below the sublimation point and the subsequent tempering stages a little below the sublimation point. Each tempering stage lasts for 15-45 min and the prod. is ground down to an average particle size of at least 2 mum in the second and subsequent stages.

Title: Automobile diesel engine with swirl chamber - has poppet valve closing passage between cylinder and swirl chamber and operated by camshaft near end of compression stroke
Inventor: SOUBIS JEAN-PIERRE
IPC: F02B19/02
Filed: 1976-02-24
Abstract: The engine has a main combustion chamber (5) above a piston (2) in a cylinder (3). A swirl chamber (7) communicates with the main chamber by a passage (6) and contains the fuel injector (8). The passage (6) between swirl chamber and main chamber is controlled by a poppet valve (11) which is closed by a spring (13) and opened by a rocker arm (14) driven from a cam (16) on the engine camshaft (17). This valve is timed so that it is closed until nearly the end of the compression stroke. When it opens air which is already compressed streams into the swirl chamber producing a shock wave which raises its temperature. This makes it possible for the engine to have a lower compression ratio.

Title: Fireproof lining for induction crucible furnaces - is moulded by removable plug and envelope stiffened with granular filling
IPC: F27D3/00
Filed: 1976-04-16
Abstract: The fireproof lining for induction furnaces, esp. for induction crucible furnaces, is made with a central, retractable plug. The life of this plug is considerably extended by placing between the plug (11) and the dry tamped material (7) of the lining a layer of enveloping material (13) such as asbestos sheet or cardboard whose thickness is up to one hundredth of the plug. The hollow plug is subsequently removed and the envelope is supported by granular material (21) within the envelope.

Title: Positive displacement compressor unloading system - connects discharge and intake chambers when predetermined discharge pressure is reached
IPC: F04B27/00
Filed: 1976-07-23
Abstract: The system is for relieving a positive-displacement compressor of load, being particularly for use on vehicles. A mechanism is actuated by the discharge pressure, via a conventional regulator, connecting the discharge chamber to the intake one when the discharge pressure reaches a predetermined value. This recycles the compressed air through the two chambers, via that in the cylinder. There may be a control chamber connected by ports to one of the center of the chambers. One at least of the ports has a closing valve, normally actuated during the discharge stroke of the compressor, and uncoupled when a pre-set discharge pressure is reached.
