Patent FR-2315706-A1 (FR)
IPC: G03B13/36
Filed: 1976-06-09
Abstract: The instrument has a grid (20), which acts as a spatial frequency filter and is movably arranged in an intermediate image plane of the beam path of the instrument, and to which there is assigned a photoelectric receiver system (23, 24) which scans light fluxes leaving the grid and converts them into corresponding electric signals which are used as control signals for focusing. The grid (20) is short relative to the extent of the intermediate image (19), and the drive means (21) for the movement of the grid are dimensioned such that the grid executes a movement extending over a plurality of grid constants.

Title: Biological purificn. plant for waste water and sewage - with circular tank divided into compartments by vertical walls
Inventor: CAMILLERI CLAUDE
IPC: C02F3/12
Filed: 1976-06-16
Abstract: Plant consists of a circular or polygonal tank with two sections; one forms the oxidn. tank and the other is divided by the wall into two concentric zones, one for decantation and the other for thickening the sludge. The circular tank is surmounted by a bridge which turns with a backwards and forwards movement around the central axis. It carries a surface aerating turbine, a portcullis type of thickener with a scraper at its base, and a rake at the bottom of one concentric zone. The effluent, after coarse screening and sand removal enters the oil-and grease-removing compartment. It leaves by gravity at the bottom to flow into the oxidn. compartment where it is purified by the bacteria of the activated sludge. It then goes through the perforated pipe into the decanter. The purified and clarified water is evacuated through another compartment. The sludge is removed from the bottom of the second concentric zone by a pump on the bridge. During construction, shuttering is simplified as compared with that required for five separate recipients. No pipe systems, with the risks of blockage, are required as the compartments touch each other.
Patent FR-2359945-A1 (FR)
Title: Composite sisal mat-glass mesh reinforcement for cast plaster panels - for high key and strength properties
IPC: E04C2/04
Filed: 1976-07-26
Abstract: Composite reinforcement for panels of plaster, etc. comprises a layer of entangled fibres of sisal or similar vegetable fibre supported by a flexible mesh, specif. of resin coated glass cords. The fibres are fixed to the mesh by entanglement by pricking. Used for strengthening cast panels for decorating wall, ceilings, etc. of buildings. The vegetable fibres provide a good key with the plaster. The supporting mesh anchors the fibres in position in the mould during casting, for more rapid panel fabrication than in processes where free non woven sisal matting is submerged manually in the cast plaster. The mesh support increases panel strength and fracture resistance.

Title: Alkali-resistant, transparent coatings for glass - consisting of layers of organo-silane, curable epoxide resin, and (neutralised) alpha-olefin-unsaturated acid copolymer
IPC: C03C17/34
Filed: 1976-08-10
Abstract: Coating consists of (1) a primer layer composed of (A) an organofunctional silane, and (B) an epoxide resin contg. an amine or polyamide as curing agent; and (2) a layer of a copolymer of a 2-10C alpha-olefin, and a 3-8C alpha-beta-ethylenically unsatd. carboxylic acid. (A) and (B) may be present in the same layer or two separate layers, A being adjacent to the glass. 0-100 Esp. 10-50% of the acid gps. of the copolymer (2) are neutralised with metal ions having an ionised valence of 1-3 when the unsatd. acid is a mono-carboxylic acid, and when the acid is a dicarboxylic acid. The metal ions may be uncomplexed or complexed. Copolymer (2) is a direct copolymer of the olefin/acid, in which the acid gps. are randomly distributed, and contains at least 70 mole % olefin, and 0.2-5 mole % acid, based on olefin plus acid. The copolymer may also contain other monomers, these being mono-ethylenically unsatd. Excellent adhesion to glass, e.g. bottles is obtd. They have good resistance to hot alkali solns. used for sterilisation, e.g. 5% NaOH at 70 degrees C, and also to abrasion. Coating provides the glass articles with a good resistance to breakages.

Title: Beheader and degutter for fish carcasses - has separately driven units, and pressing plate moves between floating guides
Inventor: SWITALA RYSZARD
IPC: A22C25/14
Filed: 1976-11-19
Abstract: The machine has a separate unit, individually driven for each operation, arranged beneath a working gulley and secured to a swinging lever. The fish are aligned for both units by a loading arrangement comprising the gulley, formed by two floating panels, and a mechanism including a plate for pressing the fish through the gulley. During the working sequences the pressing plate follows a path very close to the plane of symmetry of the gulley panels. The degutting unit, actuated by the control system, responding to the load on the fish, swings on the driving shaft of a motor, and is jointed to a telescopic arrangement, the piston rod of which is anchored to the machine frame. The loading and pressing arrangement is linked by a balance and overload clutch to the head shearing unit, and the two units can be disengaged. The fish are fed accurately forward into the working groove relatively to the working tools, esp. to the degutting tool, by a partial widening of the panels of the gulley. The machine is compact with totally enclosed gear boxes and can be used either for topping the fish alone or for both operations.

Patent FR-2381908-A1 (FR)
Title: Rotary iC engine - has two Geneva wheel type rotors meshing together and revolving in opposite directions to compress and expand gas
IPC: F01C1/12
Filed: 1977-02-28
Abstract: The engine has two rotors (1, 2) on parallel shafts (6). The rotors have recesses and projecting lobes which mesh with each other as the rotors revolve in opposite directions. A small gap between the rotors prevents friction but acts as a labyrinth seal to the escape of gases. The shafts carry gears (3, 4) which engage with each other to ensure correct contra-rotation of the rotors. A fuel air mixture is injected through a port (7) in the flank of the engine between the meshing rotors. A glow plug (8) in the appropriate position ignites the mixture. The resulting expansion produces a force on the lobes of both rotors which causes them to rotate.

Title: Automatic piloting of sailing craft - employs wind sensing blade providing control signal for rudder in water
IPC: G05D1/02
Filed: 1977-11-08
Abstract: The automatic pilot for sailing craft utilises a vertical blade in wind direction. When craft sails out of wind direction on a signal is transmitted to steering rudder immersed behind the craft. A vertical blade (1) whose axis (3) follows wind direction provides a control signal to vertical shaft (5) which is transmitted (6) through an angle to horizontal shaft (7) to point of reception (9). To prevent over control a pendulum is activated around a horizontal axis (10) and above the vertical control axis (11) of the rudder.
