Title: Ethylene-vinyl acetate copolymer coated self-adhesive tape - contg (meth)acrylate esters of polyhydric alcohols
IPC: C09J7/02
Filed: 1974-10-07
Abstract: Adhesive mixts. of (A) 30-70 (40-65) parts ethylenevinyl acetate-copolymer contg. 20-75 (30-55)% vinyl acetate, (B) 30-70 (35-60) parts one or more tackifying resins, (C) 0-15 parts inorg. filler, (D) 0-20 parts plasticiser and (E) 0-5 parts anti-oxidant, to which is added (F) 0.5-20 (2-10) parts of >=1 esters of (meth)acrylic acid with an alcohol contg. at least 2 OH gps. The mixt. is applied, pref. in molten condition, to a substrate and cross-lined with a 0.1 -10 Mrad dose of high-energy radiation to form self-adhesive tapes and films. Shear strength of the adhesive, esp. at high temps., is increased by cross-linking. Low radiation doses, prevent damage to sensitive substrates. The adhesive can be applied in soln. or, more conveniently, in molten state.

Title: Lock with solenoid actuated locking bolt - has hollow solenoids which enclose moving bolt in housing
IPC: E05B47/06
Filed: 1975-02-13
Abstract: The solenoid actuated lock has a specially robust construction. The bolt is preferably a long slender bar made from a ferromagnetic material and the solenoid arrangement has a pair of coils which are arranged at a distance around the axis of the bar. Each solenoid acts in the opposite direction so that the bar is moved into the locked and released position. The locking bar is actuated by two enclosing solenoids. The solenoid actuated lock system has a transverse locking pin which moves at right angles to the locking bar. This transverse plug is also actuated by a solenoid. For actuating purposes the transverse plug is withdrawn by the solenoid and then the bar is able to move axially.

Title: Land, water, or air born vehicle - has double or multiple propellers driven by twin cct. hydrostatic motors
IPC: B64C27/12
Filed: 1975-03-05
Abstract: A vehicle designed for travel on water or land, or through the air, employs in its simplest design, two propellers driven by two hydrostatic motors supplied with fluid under pressure by two separate circuits each with its own pump, designed to give an automatic forward travel, the first pump having a different absorption capacity from the second. In an alternative design, the pumps are the same, butt the conveying chambers are of different volume. The difference in flow may be used to control the angle of the vehicle. In further designs the hydromotors can be double motos mounted on a common shaft, and free wheel systems can be incorporated. Many further variations include different flow control arrangements, and multi-propellr versions are included.
Patent FR-2325840-A1 (FR)
Title: Display panel joint assembly - has square body with slots at corners and in faces to receive panel edges and base plate spigots
IPC: A47B47/00
Filed: 1975-04-02
Abstract: The panel (P1,P2,P3,P4) edges are inserted in longitudinal slots in an extruded square section resilient plastics material. The slots extend approximately half way to the section centre in depth. Between the slots for panels, additional slots of similar depth are formed. Base plates carrying spigots thicker than the width of the intermediate slots are fitted at the ends of the extrusion, forcing the intermediate slot walls apart. This causes the panel slot walls to grip the panels firmly and can also compensate for panels of inaccurate thickness. If desired, the base plates, which are fixed by central screws, can also retain end walls to make closed containers, or stiffen open ended assemblies.

Title: Hydraulic door closing damper - has rack and pinion connection to door and relief valve to accelerate final closing movement
Inventor: FOURNIER YVES
IPC: E05F3/12
Filed: 1975-05-20
Abstract: The door pivots on a shaft (10) which has a pinion forming a rack and pinion connection (9, 13) to the sprung sliding piston (18) of the hydraulic damper. Hydraulic oil is contained in two chambers (2a, 2b) separated by the piston but connected by two passages (15, 20). One passage has a one way valve which operates when the door is opened to provide undamped opening. The other passage restricts the flow of oil between the chambers when the door is closing. Towards the end of the closing door another valve (5) is opened by the moving piston (6), allowing free passage of the oil and a fast final closing of the door.

Title: Prepn. of grape must and fruit juices - using a trituration stage in a hammer mill
IPC: A23L2/04
Filed: 1975-12-24
Abstract: Process for the prepn. of must from grapes, possibly for use in wine-making, and of the juices from fruit berries in general, comprises the crushing of the fruits and the removal of the stalks and pips. In the case of grapes the first stage is effected by conventional means and the crushed grapes, after removal of the stalks etc., are sent by the pump to a sulphiting conduit. this is followed by trituration in a disintegrator, of the hammer type. For the fruit berries, other than grapes, the treatment starts at the trituration stage. The triturated fruit then goes by pump to a centrifuge for the sepn. of the solids; these go to a continuous screw press. The centrifuge may be replaced by a filtration unit. The triturated prod. may first be heated in a heat exchanger and then go via the collecting tank and the pump to the centrifuge or filter. When making red wine, the prod. from the hammer mill goes first to the fermentation tank before transfer to the centrifuge. All the various treatment can be effected in a completely mechanical manner without the need of manual operations; the plant is very flexible and can readily be adapted for various types of prod.

Title: Edge shaping process for stainless steel plates - includes folding and rolling edge and finally pressing lip into rectangular cross-section box
IPC: A47G19/02
Filed: 1976-05-25
Abstract: The three-stage edge-deforming process may be used to produce "Louis XIII style" plates in stainless steel. The process treats the rim (3) of the plate (1), first returning it vertically at right angles then rolling it over towards the inside of the plate, and finally machine-pressing it into a rectangular hollow box formation (4). The initial vertical return may terminate in a gentle inward curve and after the second stage the edge may have an approx. circular form. The original flat rim of the plate may be provided with 'V' section grooves. The grooves define the angles of the rectangular finished rim (4) and aid the bending process.
