Patent FR-2277233-A1 (FR)
Title: Variable capacity cylinder engine - has hydraulic ram adjusting crank system to vary capacity
IPC: F01B3/10
Filed: 1974-07-05
Abstract: A central hydraulic piston which is kept in place by a return spring operates on a central crank assembly. The hydraulic fluid causes the crank assembly to move downwards or upwards, thus varying the stroke of the piston relative to the cylinder. The clearance volume beyond the piston is thus varied and the efficiency of the engine is maintained at low powers. The drive is taken through the crank mechanism to the output shaft by means of push rods connected to the pistons and a swash plate at the centre of the drive.

Patent FR-2288317-A1 (FR)
Title: Aerial prospecting for underground mineral layers - compares electromagnetic waveforms received from different layers with reference waveforms
IPC: G01V3/165
Filed: 1974-10-14
Abstract: A primary electro magnetic field is created and directed to the zone to be prospected. The field has a waveform varying with time, and its phase and frequency components are known and are sufficient to identify the conducting mass present in the zone, these induced current set up the formation of secondary electromagnetic fields which interact with the primary field. The received signals comprise a first part whose phase and amplitude depend upon each frequency component of the secondary magnetic field and a second part which is attributable to the direct coupling with the primary electromagnetic field. Several reference waveforms are coupled in a predetermined manner to the primary field and relate to characteristic electrical responses of several different types of conducting masses. The electromagnetic signals received are compared with the reference waveforms which give optimal correlation.

Title: Movable swimming pool pontoon bridge - comprising ballasted rustless metal caisson with partitioning cross walls and platform
IPC: E04H4/12
Filed: 1974-10-21
Abstract: The pontoon bridge is for use in swimming pools up to Olympic competition size, and can be used both as a servicing base for cleaning the bottom and sidewalls in a very short time, and as a temporary partition for dividing the pool into two pools of smaller dimensions. It comprises a metal non-rusting caisson (3), with ballast in its lower section, forming a sealed space, with external walls which can provide cross-running partitions for the pool. It is covered by a platform deck (14) outside the water, able to provide a cross-running intermediate edge. There are protective grills on the plinth, running across the pool, and rails for bottom skimmer brushes (39), or on the two side surfaces for scraping the walls. A drive mechanism provides for two-way movement within the pool. The enclosed space contains a series of vertical filters.
Patent FR-2290221-A1 (FR)
Title: Ionising process for liqs. by electric field - produced by current between gold-plated electrodes
IPC: C02F1/467
Filed: 1974-11-05
Abstract: Ionising process for liqs. is intended to facilitate their absorption by the living organism and is effected by passing them through an electric field. As applied to drinks the electric field is created by two electrodes covered with pure gold; they are placed in the pouring lip of the vessel. In this case the electrodes are connected to replaceable batteries placed in the handle and covered by a plug. An ionising anti-splash nozzle can be attached to a water tap for an immediate supply of ionised water for a wide variety of purposes. Electrodes can also be fixed in the rose of a watering-can to facilitate the nutrient exchanges taking place in the soil. It is claimed that the electrodes mounted on the different types of appts. impart electrical properties to the fluds passing over them comparable to those of storm rain water at the time of its fall. Apart from betteries, the electrodes may be connected to a source of direct or alternating current; they should be arranged above the surface of the liq., when the latter is in the rest position, so as to avoid permanent contact with the liq. with the consequent waste of current.

Title: Energy amplification device for propulsion - has interconnected system of levers and gears connected to small power drive
IPC: F16H29/02
Filed: 1974-11-21
Abstract: This dual train of levers and gears amplifies the energy from a relatively weak source so as to make it suitable for example for the propulsion of a vehicle. A motor drives a shaft (5) carrying two plates (3, 4), each of which has a spigot (7, 8). The spigots are separated by a certain angular distance from the slotted ends, the levers are pivoted (12) at the centre of a toothed circular arc extension (11). This extension drives a pinion (13) which is connected by belts or chains to further gears (17) and further sets of spigoted plates (6). The shaft (15) is always driven in the same direction. Several sets of the levers and gearing are connected in series.

Patent FR-2384635-A1 (FR)
Title: Writing instrument for handicapped person - has internal spring to limit pressure exerted on point of cartridge whose upward movement is limited by inner tube of sheath
IPC: B43K21/00
Filed: 1975-01-20
Abstract: A writing instrument which is intended for use by physically handicapped persons has an internal spring to control the pressure applied to the tip. A cartridge which may be a lead pensil, a felt tip pen or a ball pen is filled inside a tubular sheath. An inner tube is fixed inside the upper part of the sheath and limits the upward movement of the cartridge. A spring, attached at one end to the cartridge and at the other end to a plug, exerts a downward force on the cartridge. This limits the force which can be exerted on the point of the writing instrument and makes it easier for handicapped people to use it.
Patent FR-2300233-A1 (FR)
Title: Windmill with variable pitch blades - pitch of blade is automatically reduced as wind force increases
IPC: F03D1/06
Filed: 1975-02-06
Abstract: A windmill has blades (1, 2) mounted in bearings in triangular frames (7) (8), so that they can rotate about a radial axis. The inner ends of the frame (7, 8) are mounted in bearings (10) at the ends of a T-shaped member which can slide axially against a spring in the rotor shaft (12). Each blade has an arm provided with a ball joint (23, 25) which connects it to the collar (26) which is keyed to the shaft (12). When the rotor speed increases with increasing wind force the angle (B) of inclination of the blade axes decreases due to centrifugal force and the bearings (10) move outwards against the spring, causing the blade pitch to reduce since the rods (30, 31) exert a force on the blade arms.
