Patent FR-2387920-A1 (FR)
Inventor: HATSCHEK FRITZ
IPC: B28B1/52
Filed: 1978-04-20
Abstract: A mixture, in particular a building material mixture, for making mouldings having largely similar mechanical and chemical properties, such as asbestos cement, is to be provided, but in which the asbestos raw material is replaced by another, in particular synthetic product. Such a mixture contains binders and fibre-type or fibrous materials as well as water. As fibre-type or fibrous materials, it contains exclusively or predominantly fibrids. These fibrids consist of organic hydrophilic homopolymers or copolymers or graft copolymers such as, for example, polyethylene, polypropylene, polyacrylonitrile, polystyrene, polyvinyl alcohol, polyvinyl chlorides, polyamides or polyesters. The fibrids can also consist of copolymers of ethylene, propylene, styrene, vinyl chlorides or of acrylonitrile with polymerisable vinyl compounds or acrylic compounds carrying hydrophilic groups, such as vinyl acetate, vinyl alcohol, hydroxyethyl methacrylate, acrylic acid or methacrylic acid. They have essentially a short-fibrous form. They are or can be fibrilated. 1 - 40 % by weight, preferably 3 - 30 % by weight, of the mixture consists of fibrids alone or of mixtures of the fibrids with asbestos fibres and/or other inorganic fibres such as, for example, rock wool, slag wool, glass fibres, carbon fibre-whiskers, boron fibres, wollastonite fibres or alumina fibres. To improve the retention of the hydraulic binders on the fibrids, preferably 0.01 - 2 % by weight, relative to binder, of cation polyelectrolytes are present.

Filed: 1978-05-23
Abstract: The profile consists of a sash frame (1) and a window frame profile (2). Provided in the gap between these profiles are an outer seal (3), a central seal (8) and an inner seal (13). The sash frame profile (1) has a chamber (6a) which is delimited on the outside of the profile by means of a wall part (15) of square shape. The window frame profile too has a space (32) between the outer seal (3) and the central seal (8), it being possible for water to be removed from this space (32) via openings (21) and two pre-chambers (18).

Title: Recovering energy from liq. at high temp. and pressure - by conversion to mechanical energy, used e.g. to pump water to safety circuit in nuclear installation
IPC: F01K21/00
Filed: 1978-07-28
Abstract: Recovery of energy contd. in a fluid e.g. water at high enthalpy level (P,t) incorporating (a) expanding the fluid to a pressure below atmos. pressures (b) introducing it into an enclosure and (c) passing through a two-phase nozzle where the fluid is partly vaporised and accelerated to form a high speed jet. The kinetic energy contained in this jet is transformed into work on the axis of a turbine. The vapour produced in the expansion of the hot fluid is condensed by cold fluid taken from outside the enclosure, to maintain the press. Po in the enclosure. The liq. which accumulates in the enclosure is taken out by a pump using a part of the mechanical work supplied by the turbine and raising the press. of the fluid to discharge the enclosure. Process is applicable partic. in the case of isolated installations where an external source of hot water is available. In nuclear power stations, the process can be used to supply water at ambient temp. to the safety circuit of the nuclear reactor.

Filed: 1978-12-22
Abstract: The brass connector (9) for a fibre optic cable (f) is cylindrical having a through passage for the cable and differing dia. portions (11,14) separated by an external screw threaded portion (74). A respective annular groove (23,32) is formed adjacent each end of the connector having wall thicknesses of 0.4 and 0.3 mm in the 1.5mm and 0.5mm walls of the differing dia. portions (11,14). A cylindrical tube (51) of a tool is screwed onto the screw-threaded portion (4) and is submerged at each end by caps (58,77) through which the cable (f) passes. As each cap (58, 77) is screwed onto the tube (51) they force respective internal press rings (62,79) against the connector ends. Thus deforming the thin walls of the grooves (22,-32) into gripping engagement with the cable (f). The ring (79) adjacent the connector reduced dia. end (14) has an annular chisel-shaped end (86) which bites into the connector end to provide a further gripping deformation. Each press ring (62,79) is in two halves for easy removal from the cable (f).

Title: Thermal redn. of metal oxide(s) - esp. aluminium oxide by discharging oxide powder into reactor to create vortex and applying electrical discharge
IPC: C22B21/02
Filed: 1979-01-15
Abstract: Metal oxide is thermally reduced by introducing oxide powder and gaseous reductant into a reactor with a tangential component to create a vortex. A dispersed electrical discharge is maintained in the reaction zone through a min. turbulence level of the gaseous medium and the temp. is maintained at sufficiently high temp. to effect redn. of oxide to metal vapour which is removed and condensed.
