Patent FR-2351398-A1 (FR)
Title: Mechanical force to fluid pressure transducer - has force applied to flap valve restricting egress of fluid from conduit in which pressure varies accordingly
IPC: G01L1/02
Filed: 1976-05-13
Abstract: A manometric transducer converts a mechanical force (F) applied to an actuating surface (30) into a fluid pressure signal (P). A primary high pressure source (P1) feeds a conduit (12) through a constriction (16) at one end. At the opposite end a flap valve (22) restricts the escape of fluid through an expanded orifice (22). Mechanical force on the flap valve brings about a pressure rise in the conduit which is available as an output pressure signal at take off point (26).

Title: Offshore structure for e.g. oil prodn. fields - incorporates fixed infra-structure, buoyant mobile superstructure and vertically movable connectors
IPC: E02B17/02
Filed: 1976-07-02
Abstract: Off-shore structure incorporates an infra-structure, a superstructure, intermediate elements for connecting the two and a permanent or demountable system for connecting the intermediate elements to the infra-structure. The infra-structure is (partly) submerged and rests on, or is anchored to, the bottom. The superstructure is buoyant enough, either by its own construction or by the addn. of buoyant elements, to be brought over the submerged part of the infra-structure, by self-propulsion or towing. Its draught is such as to allow such positioning. The superstructure carries mechanism for moving the intermediate connecting elements vertically upwards or downwards. Heavy lifting equipment, reinforcement of structures, and the carrying out of large construction works at sea are avoided and fire resistance is improved. The superstructure can put to sea at any time for repair, maintenance or removal to another site. Installation in deeper water, for an infra-structure of given height, is possible and surface stresses are reduced.

Title: Refuse and sludge composting plant - has discharge system with reciprocating upper and stationary lower grating with parallel bars
IPC: C05F17/02
Filed: 1976-10-28
Abstract: The composting plant is a vertical chamber through which the material descends. The two discharge elements at the bottom include one grating with parallel bars which can be reciprocated by a drive.

Title: Automatic weighing system for vehicle loading - operates by automatic removal of excess material from weighing container
IPC: G01G13/24
Filed: 1976-11-05
Abstract: Automatic weighing for loading of vehicles in bulk or in sacks is performed by removal of the excess.

Patent FR-2334138-A1 (FR)
IPC: G04G13/02
Filed: 1976-12-01
Abstract: An alarm watch has an electro-acoustic transducer with a sound releasing cavity containing a vibrating plate for releasing an audible alarm sound. The surface of the vibrating plate exposed to the open air is treated with a water-repellant material having the property to shed or repel water so that when water enters into the sound releasing cavity and wets the vibrating plate, the vibrating plate readily throws off the water thereby obtaining rapid recovery of the alarm sounding function.
Patent FR-2372601-A1 (FR)
Title: Machine to grate fruit and vegetables between grating cylinders - which rotate in opposite directions to increase grating pressure
IPC: A23N7/00
Filed: 1976-12-06
Abstract: The machine is of the type in which fruit is supported between a pair of slightly spaced, parallel, rotary, grating cylinders. The cylinders of a pair rotate in opposite directions and a support is provided between the cylinders to prevent fruit drawn into the nip of the pair of cylinders. The machine pref. comprises two or more parallel pairs of grating cylinders. Adjacent cylinders of two different pairs rotating in opposite directions tend to throw fruit into the nips of the two pairs. A conveyor scroll, pref. surfaced with grating material, can be used to move fruit axially along the support between a pair of cylinders. Alternatively, the support itself can be in the form of a conveyor scroll. Conveying can be effected by gravity alone by tilting the axes of the grating cylinders towards the discharging end of the machine. Used for grating fruit and vegetables, e.g. citrus fruit for essential oils, peeling mangoes. Contra-rotation of cylinders of a pair draws the fruit towards the grating surfaces of the nip. This provides a much more vigorous grating than cylinders rotating in the same direction, where fruit is grated under pressure of its own wt. only.

Title: Bay window safety shutter - has slats with offset leaves attached to hubs with spindles working in slides at each end
IPC: E06B9/06
Filed: 1977-03-03
Abstract: The safety shutter is for bay windows, having a large number of slats, each with two leaves preferably flat and fixed to a hub through which a spindle passes, fitting in a slide at each end. The leaves (16a, 16b) of the same slat are in parallel planes, offset from each other for the thickness of the hub (17), so that all slats in a set can have three or more relative positions. In the open position, the slats in a set overlap so as to form a rectangular block of no greater width than that of one of the slats. In the semi-shut position, the slats are separated and equidistant, so that the leaves of the two adjacent slats are opposite each other and in plane offset from each other for a distance equal at least to a hub thickness. In the fully shut position, the slats in the set are equidistant so that by anular displacement the leaves can be brought to bear against each other partly overlapping.

Title: Continuous casting of wide slabs - using water cooling nozzles at the middle of the axial length of the guide rolls
Inventor: HEDDERICH
IPC: B22D11/124
Filed: 1977-05-06
Abstract: Device for cooling the guide and support rolls together with the cast slab, in continuous casting plant, where nozzles for spraying coolant are located in the guide and support track. The nozzles are located above and below the cast slab, and between adjacent rolls; the nozzle outlets are situated at the middle of the axial length of the rolls and direct the coolant towards both edges of the slab and towards both ends of each guide and support roll. For use in the casting of wide slabs, where the rolls are assembled from several sections, using bearings located between the sections and at several locations along the length of the roll, to prevent bulges on the slab surface due to the ferrostatic pressure. The middle sections of the rolls, and their bearings, are adequately cooled, so that bearing seizure is avoided; the improved cooling also prevents fissures occurring in the surface of the slab.

Title: Automobile door lock with double-arm lever bolt - has contoured ratchet engaging both bolt legs at closure
IPC: E05B65/32
Filed: 1977-08-23
Abstract: The door-lock is for use for automobiles and incorporates a pivoting forked bolt (7) which acts with a pivoting cammed ratchet plate (15) to engage a staple pin (4) on edge of the door. The geometry of the bolt and ratchet plates is such that both legs (13, 14) of the former (7) are retained by counter faces (25, 31) of the latter (15) when in the locked relationship. A nominal lateral play is provided between the leading leg (13) of the bolt and the corresponding counter-face (25) of the ratchet. The normal to the interacting faces (31, 32) of the primary tooth (30) of the ratchet and the rear leg (7) of the bolt may pass through the fulcrum axle (16) of the ratchet, and the tangent to these faces may pass through the fulcrum axle (8) of the bolt, thus, eliminating couples about the axles.
