Title: Mast for sailing yachts - has turbulence forming device on leading edge to increase sail efficiency
IPC: B63B15/00
Filed: 1973-11-14
Abstract: On the leeward side of a mast surface, a configuration produces turbulence in the air flow around the mast so that the air flow detaches from the mast in a turbulent boundary layer thereby decreasing unattached flow (or increasing attached flow) between the mast and the sail. Coupled with the latter is the formation of the mast cross section to have a generally elliptical or parabolic front surface shape, a midsection formed by opposed arcs of a circle on opposite sides of the mast and a rear surface section formed by opposed arcs of a circle having a radius of curvature greater than the arcs of the midsection.

Title: Grid plate for a grid cooler - for cement clinker, has upwardly widening chamfer on lateral surface edges
IPC: F27D15/02
Filed: 1973-12-10
Abstract: Grid plates for coating clinker, esp. cement clinker are normally arranged in sequence in the forward direction of the appts. with gaps between adjacent plates. Clinker tends to become trapped between adjacent plates when the plates get hot, causing a blockage, pile up and further heating and hence expansion. Thus the blockage does not clear and the grid plates warp. The problem is overcome by having upward opening chamfers at the lateral edges, so that if a piece of clinker is trapped, only a small part of it is caught and local expansion due to increased temp. will cause the trapped part to slide out.

Patent FR-2256273-A1 (FR)
Title: Foam-impregnated non-woven fabrics compressed before curing - to give even distribution of foam through the material
IPC: D04H3/12
Filed: 1974-12-23
Abstract: Non-woven fabrics impregnated by a foamed material are made by (1) impregnating a non-woven fabric made by spinning from a molten polymer (I) and disposed in interwining loops, with an aq. foamed soln. or dispersion of a film-forming material (II), (2) compressing the material to 12-55% of its original thickness, (3) expanding and subjecting the material to a heat treatment. Non-woven fabric base is evenly impregnated with the foam and gives a product which does not make annoying noises on deformation and which has very low permanent deformation after compression. Products are useful e.g. as covering materials for seats and cushions and as filter materials. Non-woven fabric base may be e.g. of polyamides such as polycaprolactam, polyesters such as polyethyleneterephthalate, polyolefins, PVC, etc. The filaments are pref. substantially amorphous and have a diameter of 0.05-2.5 mm, esp. 0.3-1.5 mm. The non-woven fabrics may be bonded at the crossover points with e.g. a polyurethane or an acrylic latex. The fabric is generally 3-300 mm. thick. The foamed material is pref. of PVC, polybutadiene, polyisoprene, polyurethane, etc., and esp. a vulcanisable styrene-butadiene rubber latex with a solids content of >50%. The foam can be applied e.g. by foularding, followed by compression on the foulard cylinder to (esp.) 15-40% of its original thickness. After being compressed, the material expands again due to its natural elasticity, causing the foam to distribute in irregular fashion in the fabric, after which the fabric is passed into a drying and vulcanising oven.

Title: Cleat for rope or cable - exerts uniform pressure on rope due to thicker cross-section at cleat ends (SW260476)
Inventor: ROHLAND BERNHARD
IPC: F16G11/02
Filed: 1974-12-27
Abstract: The cleat (1) is in the form of a sleeve of malleable material with a central hole to suit the diameter of the rope (6) and the free end (7). The outer surface (4) of the cleat (1) has a concave profile so that the wall of the sleeve is thicker at each end (5) than it is in the centre. When the cleat is compressed between the jaws of a clamp the thicker end walls resist any tendency of the cleat material to flow in an axial direction and so maintain a uniform pressure throughout the length of the cleat and provice a more secure retention than is the case with conventional cleats.

Title: Document laminator using unfinished plastics films - eliminating use of gummed films, with reduced prodn. cost
IPC: B32B37/02
Filed: 1975-04-11
Abstract: Document laminator uses unfinished plastics films, i.e. as they come out of the extruder. The two surfaces of the two plastics films which are to be applied to the document to be protected are moistened with a solvent to render them self-adhesive. The plastics films and documents are advanced and compressed by a first train of flexible rollers, then dried with IR radiation, re-pressed, and sealed by a second train of rollers. A system of cutting by electrical resistance or cutting maching allows sepn. of the protected documents from the untreated film. The films do not have to be pre-coated with gum, nor does the machine need to use a temp. close to the m. pt. of the film with a prolonged pressing time. The use of flexible rollers allows for the extra thickness without interfering with the laminating process.

Title: Fluid control valve for motor drive - has coils pivoting armature to direct fluid to drive direction selection passage
IPC: F01L25/08
Filed: 1975-06-30
Abstract: A body (10) contains meshing rotors (12, 14) similar to gear pump rotors. The body has passages (32, 34) formed on the inside so that the gas may be directed to one side or other of the rotors, providing drive in either direction. A pivoted (50) armature (46) terminates in a cylindrical surface (60) with a smoothly hollowed indentation. This surface mates with a similar surface to which the passages (32, 34) are led and the surface (60) covers the ends of the passages when the armature is central. A central bore (36) and connecting passage (38) lead high pressure fluid to the indentation. Pivoting of the armature thus directs the fluid into either of the passages (32, 34). Precise electrical or mechanical selection of armature deflection is possible giving sensitive control of the drive.
