Title: Deflashing glass-reinforced plastic mouldings - using mould tools which produce a snap-off profile
IPC: B29C53/06
Filed: 1973-05-23
Abstract: Mouldings of mineral fibre reinforced resin with peripheral weaknesses are made by using matched moulding tools which produce a series of perforations or a zone of reduced strength between the moulding profile and extraneous flash or outlay matl. Mould tools pref. generate a peripheral nip adjusted to be just wide enough to accommodate the rovings but narrow enough to squeeze out the interstitial resin. The process is suitable for mfr. of medium or large mouldings, e. g. bath tubs, boat hulls, etc. Excess matl. may be snapped off by manual or mechanical twisting in less time (approx. 50%) than would be required by use of a portable rotary or reciprocating saws, and without the generation of dust or heat. Process is more suitable for non-linear profiles than the use of shear tools for trimming. The resin is shaped/sheared while hot and soft, resulting in lower tool wear than cold cutting operations.

Title: Rotor tip seal for rotary engine - thermal insulation slot parallel to sealing segment groove
IPC: F01C21/06
Filed: 1974-02-25
Abstract: The rotary engine has a casing, the cross-section of which is formed by two symmetrical trochoidal arcs. The rotor (3) is of triangular cross-section, the sides of the triangle being formed by convex arcs. A sealing segment (5) fits in a longitudinal groove (4) cut in the rotor at each corner of the triangle. To reduce the effects of thermal expansion and so reduce the clearance of the segment (5) in its groove (4), a narrow slot (14) is cut in the rotoro parallel to the groove (4). This slot reduces the heat flow to the groove (4) and may be filled with an insulating material such as a sintered compound of carbon.

Title: Inflatable rescue aid for swimmer - with gas bottle inflated raft in hinged capsule thrown to swimmer
IPC: B63C9/15
Filed: 1974-07-30
Abstract: A plastic capsule is made from two half shells hinged at one end, and fitted with a securing catch at the other.

Title: Foamed aluminium alloy - made by casting alloy contg. hydrogen and oxygen and permitting expansion on release of gases
Inventor: MOURET JEAN-PIERRE
IPC: C22C1/08
Filed: 1974-08-19
Abstract: Porous (foamed) Al alloy mouldings, contg. an additive elements 0.3-5 (1.5-2.5) wt. % Mg, of which the apparent volume is 0.5-2.7 g/cc, have their porosity created by a conc. of H2 of 0.5-5.0 (1-3) cc/100 g, the partial pressure of H2 in the bubbles being somewhat below atmospheric which the mouldings contain 1000-5000 (2000-3000) ppm (by wt.) of O2. The matl. has a high energy absorption capacity, achieved in curshing while its thermal conductivity is markedly less than that of the metal in mass. The method does not involve use of metallic hydrides and other thermally decomposable cpds. The foam does not form till the moment of casting so that no worker is pressed for time during prepn. by the need to avoid untoward decompsn., etc. The prods. are used for building facade panels.
