Patent FR-2205414-A1 (FR)
Title: Textile yarn - incorporates metallic film to produce a reflective characteristic
IPC: B32B27/00
Filed: 1972-11-06
Abstract: A textile yarn having a surface coating of reflective metallic material (e.g. aluminium) is coated on its reflective surface with a thin layer of a copolymer including >=75% ethylene and >=1 monomer(s) of acrylic a acid methacrylic acid or acrylic or methacrylic alcoyl ester acids with 1-3 atoms in the alcoyl gp. Pref. the copolymer coating constitutes 1.5 gm/m of the yarn. A reflective coated polyethylene terephthalate film is coated on its reflective surface with a copolymer and laminated with a second reflective coated film between presser rolls such that the metal coating contacts the copolymer coating on the first film. The resulting laminated film is subsequently split into filaments. Alternatively a plastic film coated on both surfaces with a reflective coating is subsequently coated on both the surfaces with the copolymer. The copolymer coating prevents the yarn from being dyed during subsequent dyeing processors and also prevents degradation.

Title: Thermal engine operating at low temp - with fluids of different boiling points and extracts heat from atmosphere
IPC: F03G7/04
Filed: 1974-02-19
Abstract: The engine works of a thermo-dynamic cycle which employs two fluids of different boiling points such as water and ether and depends on the different vapour pressures of the fluids when both are at the same temperature. The reservoir contains a mixture of water and ether which evaporates when heated, the lighter fraction (ether) rising to the top, and is delivered to one cylinder, whilst the heavier fraction (water) is delivered to the other cylinder. The higher vapour pressure of the ether moves the pistons connected by a rod. A valve is then operated to supply ether to the second cylinder and water to the first.

Title: Mechanical lift line fault locating system - has galvanometer needle with disc moving past optoelectronic detectors
IPC: B61B12/06
Filed: 1974-09-09
Abstract: The safety and fault-locating system is for mechanical lifts such as ski-lifts. There is an outward and a return safety line, with opening contracts and stop buttons in series. A current from a stable source flows through the line, remaining constant as long as resistance does not vary. Faults causing current variation are detected by a galvanometer, the needle of which is fixed to a disc moving in front of opto-electronic detectors. At each opening contact except the first there are adjustable resistances between the outward and return lines. The values of these resistance are chosen so that, depending on the contact opened, the galvanometer disc places itself opposite the corresponding detector, which works in conjunction with a fault-locating circuit. A time delay is provided, so that movement of the disc past the other detectors does not activate any of the other locating circuits.

Patent FR-2283550-A1 (FR)
IPC: H01L21/76
Filed: 1975-08-27
Abstract: Described is a molecular beam technique for fabricating semiconductor devices from Group III(a)-V(a) compounds. To form planar isolated devices, an amorphous insulative layer is formed on selected portions of a monocrystalline substrate of the Group III(a)-V(a) material which is at least semi-insulating. The amorphous layer may be formed by deposition of an oxide (e.g., SiO2), anodization of an oxide (e.g., native oxides) or by conversion of a surface layer of the substrate (e.g., by grit blasting). When a molecular beam containing Group III(a) and Group V(a) elements is directed at the surface, which is preheated to a temperature in the range of 450 DEG  to 675 DEG  C, monocrystalline Group III(a)-V(a) material grows on the exposed substrate whereas polycrystalline Group III(a)-V(a) material is simultaneously formed on the amorphous layer. The polycrystalline and monocrystalline surfaces are substantially coplanar. The polycrystalline material has a resistivity high enough to provide electrical isolation between active devices formed in the monocrystalline material. Examples of such active devices, which are also described, include beam-leaded Schottky barrier mixer diodes which have reduced parasitic capacitance and sealed-junction Schottky barrier IMPATT diodes. To form devices in which isolation is not required, the same procedure is followed except that neither the amorphous layer nor the substrate need be made of high resistivity material.
