Patent FR-2232720-A1 (FR)
Title: Device to maintain constant ventilator gas flow - has spring to balance effect of dynamic press. on blocking disc
IPC: F24F11/75
Filed: 1973-06-06
Abstract: Control valve to maintain essentially constant gas flow rates, within a given range of upstream and downstream pressures. The valve consists of a passage of varying circular cross-section, formed by cylindrical and conical sections, and an axially moving disc which progressively blocks the passage. The disc is mounted on a central shaft which is pivoted on a transverse strip. The transverse strip is itself pivoted round an axis essentially tangential to the flow passage. The effect of dynamic gas pressure on the disc tends to close the passageway, and this is resisted by a balancing spring acting on the pivoting strip. The balance of these forces gives essentially contrast flow through the valve.

Title: Multiple item handling process - pair of jaws grip opposed sides of items placed in flat array
IPC: B66C1/46
Filed: 1973-07-25
Abstract: The process is for transporting items in three directions, and they are first grouped according to a prearranged plan, leaving one or more spaces between them. Pressure is then simultaneously exerted on them in opposite directions parallel to their supporting surface, and friction is produced between the items on the inside. The group is then lifted and transported to the unloading point, where the pressure is released. A mobile support can be used, with two moving jaws acting against the outside of the group, also a series of protrusions shaped to fit in the spaces between the items.

Title: Hydraulic turbine driven by centrifugal reaction - flexible belt co-operates withvanes to control flow
IPC: F03B17/00
Filed: 1974-06-06
Abstract: The turbine (1) is mounted on the shaft (5) and has a number of equally spaced radial vanes (2) welded to the hub (19). A belt (8) passes around the tips of the vanes (2) and drives a tensioning pulley (9). The belt tension is adjusted by the screw (14) in the stirrup (13). The casing (12) has an end cover with ports which direct the fluid flow into the spaces enclosed by the belt (6) and the vanes (2). When the turbine rotates in the direction of the arrow (17) the centrifugal force generated ejects the fluid from between the vanes (2) as the vanes lose contact with the belt. This centrifugal force can be used to drive engines.

Title: Pyrotechnical, lamellar charge in combustion inhibiting sleeve - is moulded flat and rolled into cylinder fitting projectile
Inventor: RAMOND JEAN
IPC: C06B21/00
Filed: 1975-12-12
Abstract: The cylindrical sleeve of combustion inhibiting resin enclosing a pyrotechnical charge for hte propulsion of a missile or rocket, is produced in a flat mould. The charge is an assembly of relatively thin plates of an explosive based on nitrocellulose and nitroglycerine, arranged lengthways in the combustion chamber of the projectile. The plates are aligned radially to the central axis of the missile, with their outer long edge zones embedded in the combustion inhibiting sleeve, and production is effected in a series of steps. The explosive lamellae are arranged in a frame, parallel to each other, at a predetermined pitch, so that the long edges to be embedded, all lie in the same plane. The assembly of frame and plates is positioned in a mould formed by a shallow tray, the bottom of which delimits the development of the circumference of the sleeve of combustion inhibiting material. The explosive plates are enrobed with the inhibiting resin in the unpolymerised condition up to a determined height above the coplanar edges of the explosive plates, corresp. to the depth to which they are to be embedded in the sleeve. After setting, the layer of combustion inhibitor is ejected from the mould, and the frame and plates are separated. The layer of resin is then rolled into a cylinder with its opposing edges in contact. A pref. additional step involves the laying into the mould of a plate with slots for the explosive plates, and corrugations which produce an additional depth of resin against the sides of the plates. Method dispenses with the need to make a cylindrical core in a mould using a centrifuge, so that a number of operational steps are eliminated.

Title: Construction joints for sides of furniture - ribs on undersurfaces interlock and held by compression between flexible cores
IPC: E04B1/61
Filed: 1976-02-19
Abstract: Each side comprises a flat outer sheet (2, 12) and has, on its undersurface a series of straight ribs spaced transversely across it. Each rib is of composite construction, being composed of a flexible core (4, 14) of compressible material, such as rubber, with its outer sides (6, 16) of a rigid material. In use, the ribs fit into the spaces between the ribs on the other side, this space being less than the width of the rib, to provide a compression fit the two mating sides form a 90 deg. corner (20a). Ring angle brackets working on the same principle can also be used for the joint.

Title: Elastic shroud for electrical connector - has two insulating concertinas expanding to cover contacts as connector halves separate
IPC: H01R13/44
Filed: 1976-03-10
Abstract: The elastic shroud, for an electrical connector, consists of two concertinas made of rubber or a similar insulating elastic material. They expand when the connector halves are generated and shroud the contacts thereby preventing them from coming into contact with metal objects or parts of the human body. Each shround consists of a conical part (11, 12) containing one connector half and a concertina part (13). The concertina has a collar (10) at its outer end. The collars (10, 10') of the two shrouds are shaped so that they mate with one another. To lock the connector halves together the halves are pressed towards one another thereby compressing the two concertinas.
