Title: Bird and animal scaring gun using gas explosions - uses two explosion chambers ignited one after other by piezo-electric ignition of gas in chamber
IPC: A01M29/20
Filed: 1982-03-11
Abstract: The bird and animal scaring device uses an explosive detonation to scare birds and animals away from crops. The scarer is mounted on a tripod so that it is free to rotate about the vertical axis, and has two explosion chambers (30,33) with an amplifying horn (24,31) extending the chambers. A gas cylinder (14) provides the fuel. Each explosion chamber is linked to an automatically closing valve connected to a variable volume chamber (35) having a flexible wall (46) which presses against a control rod (48). The rod (48) acts on an over-centre mechanism (69,73) to open the gas valve (40), and also on a hammer (62) which strikes a piezo-electric impulse generator (63) used to ignite the gas. A similar mechanism is fitted in the second chamber and is set to ignite the second chamber before the first chamber.

Abstract: The rotary indexer is for documents and is situated, in a raised position, on a desk. The rotary volume is contained between two thin spaced horizontal discs in which are radial grooves for sliding vertical partitions. The partition spacing is chosen to suit the width of the documents to be indexed. All the spaces between the disc grooves are numbered and trapezoidal shelves can be placed between the separators, supported by horizontal rods. These rods have their ends fixed in holes in the partitions.

Title: Portable electrically driven log splitting tool - uses two conical cutters driven by electric motor through reduction gearing to transversely split logs
IPC: B27L7/04
Filed: 1982-04-30
Abstract: The portable log splitting tool has two parallel conical cutters (4,5) mounted on a carrier (2) for a drive mechanism which rotates both the cutters (4,5). The cutters have a threaded surface, and one (4) is of larger dia. than the other (5), the smaller dia. cutter being also slightly shorter than the other. The tip (7) of the larger cutter is at a different angle to the main part, forming a sharper point for easier initial penetration into the log. The drive mechanism is housed in a protective enclosure (14) with handles (3), a control switch, and an electric cable emerging. An electric motor (19), under the cover, drives a worm gear (17) through a belt coupling (20). The worm gear runs on gear wheels (15,16) on the end of the conical cutters.

Title: Coupling for terrestrial or marine seismic flutes - has two assemblies with element taking up play between connector support and assembly
Inventor: BONNEAU ROBERT
IPC: G01V1/20
Filed: 1982-06-23
Abstract: The coupling for terrestrial or marine seismic flutes comprises two cylindrical assemblies placed respectively at each of the ends of the two flute sections to be coupled. Each is provided with an anchorage which assures a rigid joint of the two assemblies, as well as a device for fixing the axial traction elements onto an exterior sealing sheath.

Title: Method and device improving the operation of vertical wind turbines with lift, by passively controlling incidence of the sails with decreasing amplitude
IPC: F03D3/06
Filed: 1983-07-08
Abstract: Each sail, pivoting about a vertical axis located in front of its centre of lift, and balanced by ballasting, is returned to the tangential by a device providing an opposing torque, less than the aerodynamic moment exerted by the resultant wind, and proportional to the sum of the moments exerted by the ambient wind and the relative rotational wind. The result is obtained by a mechanism for driving the sails responding to precise criteria, and actuated simultaneously by two forces, one controlled by an anemometer and the other by a counterweight or tachometer. Depending on the incidence of the resultant wind, inversely proportional to the relative speed wR/V, the angle of incidence of the sails becomes zero at relative speeds greater than 4, beyond which the turbine operates as a fixed-blade machine. The invention gives vertical wind machines with lift the following improvements: - automatic start-up; - enhanced torque at low speeds; - limitation of power by obscuring some of the sail structure; - stopping by feathering commanded during operation; - reducing the loads, allowing lightened structures.

Patent FR-2539501-A1 (FR)
Inventor: KARLSSON LARS
IPC: F41H3/02
Filed: 1984-01-09
Abstract: The invention relates to a thermal camouflage comprising a strengthening layer (4), e.g. a woven material, on which a polyethylene film layer (1), metallized on one side, has been laminated with the aid of fusion adhesive (3). On lamination the surface is embossed such as to make it mat. Since the polyethylene is transparent for infrared, it has low self-radiation. By means of the metal layer (2) there is obtained radiation insulation so that the outer layer (1) is in a thermal equilibrium which is hardly affected, e.g. by a warm object which is covered with the material, and the outer layer has a low emission ability of about 0.6-0.8, depending on thickness and pigmentation. By applying further layers (5), patchy images may be obtained with infrared reproduction in the wavelength ranges of 3-5  mu m and 8-14  mu m.

Abstract: Hydraulic control device comprising a flow rate regulating directional control valve 16 and a braking device 52, 71, 93. During braking, the fluid delivered by the pump is directed by the flow rate regulating directional control valve and a non-return valve 38 towards the brake cylinder 93. Pressure is then exerted on the small piston 52 which is positioned so that a flow rate of control oil flows from the pump to the reservoir and so that the pressure fluid flows out towards the braking device. The small piston 52 forms, together with the flow rate regulating directional control valve 16, a controlled pressure limiter, the flow rate of control oil being restricted by a valve 57 of the small control piston 52.
