Patent FR-2248224-A1 (FR)
Title: Exercise machine for sitting a person - has spring loaded pedals on end of a shaft oscillating about a central point
IPC: B66C1/36
Filed: 1973-10-19
Abstract: The lever closing the mouth of the hook is instantly locked on application of load, and to achieve this the inside of the hook on the mouth side is shaped, by thickening the hook at this point, to form an inclined surface. The load forces the sling to slide down this surface to the bottom, whereupon the hook is locked shut as soon as the crane hoist rope starts to stretch. The inside fo the hook can basically be curved in a semicircle, being thickened on the mouth side to form the inclined surface. In the closed position the foot of the inclined surface can lie in the vertical plane passing through the lever pivot axis and that of the hoist rope eye.

Title: Rigid cover plate for car body installation hole - has thermoplastic sealing and location ring to snap fit into aperture
IPC: B62D25/24
Filed: 1974-11-20

Title: Thermoforming air permeable materials - to give accurate relief mouldings by vacuum forming assisted by excess air pressure
IPC: B29C51/00
Filed: 1975-11-26
Abstract: Thermoforming a sheet of material by placing it above the mould, heating and bringing it into contact with the mould by creating a vacuum between the two, is assisted by establishing a uniform excess pressure of gas, e.g. air, above the sheet so that it is brought into close contact with the mould both by excess pressure and vacuum. The excess pressure may be increased progressively to a constant value, and may first use warm gas whose temp. decreases progressively. The thermoformable material may be air-tight, or may be a composite of such a material joined or bonded with a crosslinkable adhesive to a non-air-tight material e.g. fabric. The mould may be in relief and may be an article to be coated. Used for forming fine designs, reliefs, murals, maps, imitation cane work from fabrics, felts, moquettes, foams etc. Mouldings in sharp relief may be made with precision and air-permeable materials may be moulded without alteration of appearance.

Title: Anti-blast flap for inlet of ventilation system - has flap held by solenoid and released by time switch to close automatically via gravity hinge with horizontal axis
Inventor: CUEILLE PIERRE
IPC: F24F11/02
Filed: 1976-02-20
Abstract: The anti-blast flap is designed to protect building ventilation systems from the effect of external explosions and automatically descends to seal the ventilation duct inlet. The flap pivots about a horizontal axis aligns horizontally when open and at 45 deg. below the horizontal when closed. Two alternative types of lock hold the flap open, and a third time-switch controlled lock holds the flap closed. A jack acts automatically to re-open the flap. The locks holding the flap open may be a jack operated bolt and an electro-magnetic contact. The former is deployed under normal circumstances and is replaced by the latter in times of emergency. A blast is detected by remote sensors, the magnetic lock de-energised and the flap drop closed. A solenoid operated bolt holds the flap closed, with draws when authorised by the time switch, and the jack lifts the flap back to the open station.

Title: Sewage detritus screen with automatic rake - has tensioned bars in rigid frame and vertically reciprocating rake which pivots to retract
IPC: E02B8/02
Filed: 1976-12-14
Abstract: The machine-raked screen is for use on sewage effluent and has a grill of vertical bars traversed by a vertically reciprocating and oscillating rake. The bars are axially tensioned by end anchorages in a partic robust rectangular frame, and the rake whilst aligning horizontally during its working ascent, pivots to both disengage and engage the grill. The arrangement obviates clogging and jamming of the rake. At the top of the ascent the rake pivots to clear the gril with the teeth of the rake dropping and adopting an inclined position. The tips of the teeth are now lower than their roots, and tthis retractive motion of the rake may be used to deposit the detritus in a chute to a collection skip. The rake remains in this retracted position during the descent whence the reverse pivoting motion takes place. The rake may form the bar of an 'L' shaped lever which picots about the top of the leg under the section of a triangulating jack.
