Patent FR-2367087-A1 (FR)
Title: Hydrophobic polymerised masses contg. active substances - for the controlled release of insecticides, insect repellents and perfumes
Inventor: GAUSSENS GILBERT
IPC: C08F291/00
Filed: 1976-10-08
Abstract: A hydrophobic substrate contains in its mass a polymerised and grafted chemical substance which is either hydrophobic or is soluble in a hydrophobic solvent. The chemical substance is liberated into a medium (gaseous or liq.) when in contact with that medium. Typically the substrate is a thermoplastic polymer such as polyvinyl acetate, a polyether, etc. and the chemical substance is capable of swelling this polymer, such as O, O-dimethyl-O-(2,2-dichlorovinyl phosphate). The substrate is partic. useful for the controlled liberation of insecticides into the atmos., but it may also be used for insect repellents and perfumes. The substrates may be used to liberate materials which are unstable or insoluble in water and polar solvents. The amt. for active material contained may be adjusted by varying the degree of cross-linking, and the liberation of that material is controllable.
Patent FR-2373896-A1 (FR)
Title: Connector parts locking and unlocking device - uses spring-loaded interior bolt and sliding sleeve performing camming action on bolt
IPC: H01R13/627
Filed: 1976-12-10
Abstract: The electrical connector locking and unlocking system has one or several locking bolts (9) mounted inside the female element (1) of the connector. The bolts (9) are designed to engage, under the action of a spring into a throat (7) formed in the male element near to its end. Each of the bolts (9) has at its inner end a ramp which, when the male element (4) is slid into the female element (1) finds against the male element (9). Contact with the male element (4) comprises the bolt (9) so that it engages fully into the throat where it locks together both the male and female element. The system has also an unlocking ring (16) which is mounted so as to slide over the female element (1). The ring (16) has a shoulder (17) near to the exterior end of the locking bolt (9). By sliding the ring (16) towards the front of the female element (1) the ring (16) presses the locking bolt down which unlocks the two parts of the connector.
Patent FR-2378968-A1 (FR)
Title: Safety valve for high pressure hydraulic or pneumatic system - has annular piston acted on by downstream pressure which opposes spring to hold valve open
IPC: F16L55/10
Filed: 1977-01-31
Abstract: The safety valve for high pressure hydraulic or pneumatic supply line has a cylindrical body (4) with an inlet pipe (1). The outlet fitting (10) is retained in the body by a spring ring (36) and supports an annular piston (28). The valve head (37) is fixed to the boss (33) which is attached by radial ribs to the piston (28). The annular piston is exposed to the downstream pressure through the orifice (40) so that when the downstream pressure fails, the upstream pressure overcomes the force of the spring (26) and pushes the valve head (37) onto the seat (21). A small groove (39) in the valve head permits a small leak to allow the valve to re-open when the cause of the failure is rectified.

Title: Lighting fixture panel for false ceiling - has four support bars in slots with serrated edges
IPC: F21V21/04
Filed: 1977-03-09

The frame is supported from the ceiling beams by four flat bars (9). The bars project through slots cut in the side members of the frame (1) near the corners. The inner ends of the bars (9) are supported by brackets having slots with serrated edges. By choosing the correct combination of a slot in the frame and a serration in the slot in the bracket (11), the bars can be adjusted to support the frame at the correct height so that the flanges are flush with the surface of the false ceiling.

Title: Solar heated chamber for drying fruits and roasting grain etc. - eliminates parabolic reflector with associated problems of wind resistance and shadow
IPC: F26B3/28
Filed: 1977-12-16
Abstract: The installation is of the type in which solar radiation is conc. in a zone which is insulated against heat loss. The installation is low-profiled, flat-topped and basically of rectangular cross-section. Solar radiation is received directly from above into a thermally insulated heating chamber. Flat lenses are pref. located above a small glazed opening in the top of the heating chamber, forming a solar trap. Each heating chamber pref. comprises a rotary cell with fresh air inlet and an outlet for exhausting fumes so that the glass of the solar trap is always clear. Used e.g. for drying beans. Without a parabolic reflector, the installation is low-profiled and does not offer appreciable wind-resistance. Without reflector and supporting superstructure, the radiation is taken directly into the top of the chamber without shadow problems.
