Title: Simultaneous biaxial orienting of extruded polypropylene- - lay-flat tubes
IPC: B29C48/10
Filed: 1969-09-26
Abstract: Simultaneous biaxial orienting of extruded polypropylene lay-flat tubes. G1-. is effected by rapid cooling of the downwardly extruded tube to prevent excessive crystallisation of the tube and thereby improve the rate of biaxial orienting. Rapid cooling of the tube is effected by controlling the dia. of the tube using on the one hand an inner presser frame formed by a diameter control device provided at its upper end with outlets for the cooling liquid and at its lower end with a cylindrical member whose outer surface is provided with helical grooves for guiding of the inner liquid discharged through the outlets, and on the other hand, an external cooling bath which surrounds the inner presser frame projecting through the base of the cooling bath. Annular space between the bath and the presser frame is closed by an elastomeric ring such that egress of the outer liquid is prevented and the tube is cooled rapidly by direct contacting of the inner and outer walls of the tube with the cooling liquids.

Patent FR-2221334-A1 (FR)
Title: Protection device for boat during laying-up - includes flexible plastic sheath conforming to shape of hull
IPC: B63B59/04
Filed: 1973-03-14
Abstract: The plastic sheath completely encloses the submerged part of the hull to a level above the waterline. Fresh water is pumped into the space between the hull and the plastic thus displacing the seawater. The presence of fresh water reduces the rate of marine growth, and the rate of electrolytic corrosion on steel hulls. The sheath is placed on position by passing from one side of the boat, under the keel, and then up the other side of the hull. The fresh water is pumped through a tube extending into the bottom of the space formed.
Patent FR-2227508-A1 (FR)
Title: Heat exchanger - with variable flow cross section to promote turbulence
IPC: F04B39/00
Filed: 1973-04-26
Abstract: The heat exchanger comprises two co-axial conical sections, one heat transfer fluid flows between the inner and outer conical sections, the second fluid circulates through a jacket on the outside of the outer cone. A block is located within the inner cone, the annulus between the block and the inner cone providing a further flow passage for the second heat transfer medium. The outer cone is fixed while the inner cone is mounted on an axial shaft which moves axially in stuffing boxes in the outer cone to provide a fluid seal. Reciprocating motion of the shaft causes variation in the flow cross section annulus from zero to a max. value. The axial oscillatory motion of the inner cone can be induced by the flow of the heat transfer medium, return motion being effected by gravity or a spring. Mechanically induced oscillation of the inner cone, together with a system of axial seals and check valves can be used to simultaneously pump the heat transfer medium.

Title: Improvement to folding of hang gliders - has double folding of main components and automatically locking hinges
IPC: B64C31/032
Filed: 1974-02-20
Abstract: The invention is aimed at avoiding the necessity for removable parts such as pins, clips, etc. used in the assembly and folding of hang gliders to and from the transport condition, and at reducing the size of the machine when in the transport conditions. The frame consists essentially of a centre keel, two diverging arms which are held apart by two cross-members. The machine folds as follows: The keel folds at hinge. The arms fold once and the other arms fol twice, while the bracing mast and legs fold at given locations. Due to the number and arrangement of the hinges the glider can be folded into a remarkably small space without removal of any of the component parts.

Title: Fuel injector pump - with delivery rate dependent on plunger position with respect to elliptical fuel return opening
IPC: F02M59/26
Filed: 1974-05-10
Abstract: The pump housing (1) contains a boring (2) in which a plunger (3) is able to reciprocate and at the same time turn. A fuel delivery chamber (15) with a delivery pipe union at its upper end and a spring loaded non return valve at its lower end is screwed into the housing above the plunger boring and amplifies fuel impulses. The cylinder boring (2) has inlet and overspill openings (8, 9) in communication with the pump fuel reservoir. The plunger has an axial boring (11) extending from its crown (10) and opening out at an annular regulator groove (12) formed in its outer surface and at right angles to the plunger axis (0). The external annular regulator groove is in communication with the overspill channel (9) when the plunger starts its delivery to produce a gradual pressure. Since the overspill channel opening is elliptical, four sections are available to regulate the return flow when the plunger is turned.
