Patent FR-2313263-A1 (FR)
Title: Multiwing aircraft for agricultural work - can fly at low speed without risk of stalling and has variable incidence front wing
IPC: B64C39/08
Filed: 1975-04-03
Abstract: The aircraft has two main wings (2, 3) at the front and two main wings (2bis, 3bis) at the rear. The two front wings (2, 3) are connected by control rods (4) to a joystick (6) so that their angle of incidence can be controlled. In addition a smaller wing (1) mounted above the main wing (2) also has a variable angle of incidence. The rear wings (2bis, 3bis) are fixed but the angle of incidence of the smaller wing (1bis) can be controlled. This arrangement of wings and control surfaces enables the aircraft to fly at speeds as low as 50 to 70 km per hour. This feature makes it especially useful for crop spraying and similar agricultural work.

Title: Oscillating conveyor head for workpiece alignment and sorting - has screw-thread-shaped inclined track along inner side wall
IPC: B65G27/02
Filed: 1975-08-20
Abstract: The inlet to the track begins approximately in the centre of the floor and progresses from there in a spiral form on the inner side wall of the conveyer head. The angle of slope of the track continuously increases relative to the axis of the oscillating head. The head has an approximately hyperbolic-shaped cross-section whereby the track rises continuously from the centre to the side wall. The track is in the form of ribs projecting from the inside of the head with the supporting edges of the ribs stand approximately at right angles to the base surface along the spiral-shaped course of the track. The head is particularly designed to convey and align flat parts transported on edge.

Title: Bobbin winding yarn control - has latch needle to pull initial end of yarn under wound yarn coils to be held in place(NL-9.3.76)
IPC: B65H65/00
Filed: 1975-09-05
Abstract: An apparatus is claimed to trap and secure the end of a yarn on the bobbin, in an automatic winding machine with a latch needle mounted axially parallel with the counter pressure unit over the winding zone of the bobbin. As the counter pressure unit over the winding zone of the bobbin. As the counter pressure and bobbin rotate together, the latch needle is withdrawn in a series of back steps to pull the cut yarn end under the coiled windings of yarn. The mechanism ensures that the initial end of the yarn is held securely in place, without the use of an adhesive strip or other securing method, giving a clean withdrawal without affecting the user textile machine, partic, a sewing machine drawing thread off the bobbin.

Title: Machine for extracting energy from rivers and tides - has endless chain of rectangular paddles in hollow wall with water passage near bottom
IPC: E02B9/00
Filed: 1975-11-17
Abstract: A wall is built across a stream or tidal way with an opening (3) perpendicular to the stream in its lowest part. This produces an acceleration of the flow and a rise in the water level. Within the wall there is a series of rectangular blades (5, 6) running of whole length of the opening. They are propelled in a combination of motions by the movement of the water so that the forces exerted on them are added together. The blades are connected to each other by hinged links (2) to form an endless chain. At the two ends of the opening the chain revolves round drums in the form of a regular polygons whose sides have the same dimensions as the blades.

Title: Hydraulic pump for wide pressure and flow ranges - uses diametral dilation of close coiled helical spring to pressurise fluid
Inventor: MEYER YVES
IPC: F04B43/08
Filed: 1976-07-30
Abstract: A hydraulic pump capable of a wide range of delivery pressures and flow has a cylindrical body (12) housing a valve block (14) which is connected to the input shaft (54) by a close coiled helical spring (22). The spring (22) is made from square section wire and is enclosed in a flexible sleeve (30) and has a flexible lining (34). When the shaft (54) is given an angular oscillation, the coils of the spring (22) are alternately wound up and unwound. When the coil diameter decreases, oil is drawn into the outer chamber (20) through the valve (44). When the coil diameter increases, this oil is forced into the inner chamber (28) and then forced out through the valve (46) on the next cyclic decrease in the diameter of the spring (22).

Title: Milk serum protein recovery - by concentrating, neutralising, heating, acidifying and filtering
IPC: A23J1/20
Filed: 1976-08-19
Abstract: Milk serum proteins are recovered by first concentrating the milk serum to increase its dry extract concn. between 3 and 8 times, followed by flocculation and physical sepn. Coarse flocculation is effected by intense acidification, followed by a 15 minute rest period to produce particles of >=1mm size. The milk serum is pref. neutralised to pH7 heated to 90-95 degrees C, then acidified to pH is approx. 4.6. Sepn. is pref. effected by a rotary filter having 1-10 mu size openings. The preliminary concn. eliminates a substantial quantity of water, which does not then require subsequent heating. The vol. redn. also means that the treatment equipment can be smaller for a given prod. hence lessening the investment costs.

Patent FR-2382596-A1 (FR)
Title: Machine utilising energy of sea waves - has caissons hinged together to pump water to high level for subsequent re-use to power turbine
IPC: F03B13/18
Filed: 1977-03-02
Abstract: The machine has a central caisson (1) floating partly submerged in the waves. Two auxiliary caissons (3) are hinged (2) to either side of the central one. The side of the auxiliary caisson slopes away from the hinge to leave a space which is closed by a bellows (4). Each auxiliary caisson has a water inlet (5) with a filter (6). There is a non-return valve (9) between the auxiliary caisson and the bellows and a non-return valve (10) between the bellows and the central caisson. Under the action of the waves the auxiliary caissons swing about the hinges (2). This varies the volume of the bellows and thus pumps water through the non-return valves into the central caisson and into an outlet (11) from it.

Title: Tied bale production machine - uses reciprocating ram in baling chamber and acting against tied bale in outlet
IPC: B65B27/12
Filed: 1977-03-08
Abstract: The machine produces tied bales of paper or similar material, using a tied bale (78) positioned between a top and a bottom wall, with one end near the outlet from a bale-forming chamber. A ram (26) reciprocates in this chamber, into which the material to be baled is loaded. The action of the ram gradually forms a bale (82) against the end of the tied bale, at the same time thrusting the new one between the top and bottom walls and the tied one out from between them. The tied and untied bales are parted after the former has been fully expelled from between the walls, after which horizontal loops of strip material are placed round the untied one.
