Patent FR-2112420-A1 (FR)
Title: Expanded resin sheet - by extruding thermoplastic resin into expansion zone between moving convex and concave surface
IPC: B29C44/28
Filed: 1971-11-02
Abstract: Expanded thermoplastic resin sheet is produced by extruding an expansible synthetic thermoplastic resin through a die slot into an expansion zone defined by two opposed curved surfaces held at a temp below the extrusion temp. one of the surfaces being a concave surface displacing in the extrusion direction, and the other surface being concave, so that expansion of the resin occurs as it passes through the expansion zone, and the curvature and relative spacing of the surfaces being such that they contact the expanding resin. Smooth finish is produced on the upper and lower faces and tearing of the sheet is avoided. Sheets of different thicknesses, densities and types can be produced.

Title: Suppositories for introduction into digestive tract - contg. vibrators or medicaments
IPC: A61H23/02
Filed: 1973-07-16
Abstract: Solid suppository, for introduction into the digestive track, does not melt and can be expelled; and contains means which act on the walls and/or the contents of a portion of the alimentary canal. One form comprises a body, of a synthetic material such as polyethylene, with a central cavity which can be closed by a screwed stopper. The cavity houses a small, short life electric cell; flexible conductors connect the cell to an electronic circuit in a block which emits electric impulses to the ferro-magnetic nose cap via the conductor. The nose-cap is forced into a groove in the upper part of the body. The impulses have a fixed frequency and stimulate the smooth intestinal muscle; they reach the wall of the large intestine either directly or indirectly and cause a contraction of the wall. The suppository is partic. suitable for the treatment of chronic constipation; the magnetic nose-cap allows it to be controlled or immobilised by means of an external magnet.

Title: Two-compartment syringe for parenteral injections - for successive injections of two liquids
IPC: A61M5/315
Filed: 1973-11-19
Abstract: Two-compartment syringe is intended for the parenteral injection of two prods. one after the other. It comprises two cylinders the latter being movable by a plunger fixed in a plug at the end of the second cylinder. The other end of the latter is fitted with a membrane. The end of the cylinder is also fitted with a membrane and is arranged to receive the double-ended needle which can successively pierce the two membranes. The second cylinder can slide inside the first cylinder when the plunger is pushed; the liq. in the large cylinder is then evacuated through the needle. As the piston moves forward the liq. contd. in the second cylinder can then be injected. The device is for use in those cases where two liqs. are to be injected successively, without the liqs. coming into contact. The syringe can be sterilised and delivered in a sealed package. The device also finds a use in analytical laboratories for the successive delivery of two prods. the relative quantities of each being exactly determined in the preliminary packing.
Patent FR-2209594-A1 (FR)
Title: Rotary filter for woodpulp fibre recovery - cylindrical screens are built into large rotating drum and fibres blown into screw collector
IPC: B01D33/073
Filed: 1973-12-10
Abstract: As the drum rotates, successive screens become submerged in the liquor which flows through and away, leaving a layer of fibres on the screen. Eventually the cylinders re-emerge, by this time well coated with fibre. At the uppermost point of the cycle, the liquor exit port engages with an air supply. Inside the cylinder are longitudinal nozzles pointing towards the central axis which serve as liquor draw off devices and as blow back nozles and it is into these that the air blows. Also towards the top of the stroke, a cog on the shaft of the cylinders engage engage with teeth on the main drum support, causing the cylinders to rotate. Thus an air blast blows through the rotating cylinder and discharges the fibres into a screw conveyer mounted on the main drum axis below.

Title: Drive for agricultural machinery with rotating tools - has gear change handles with locking device preventing simultaneous actuation
IPC: A01B33/08
Filed: 1974-04-05
Abstract: The geared drive is used especially for agricultural machines which have rotating shafts carrying soil working tools.
