Title: Insulating panel for building - comprises main frame containing insulation covered by layers of finishing material
Inventor: MINIOU ROGER
IPC: E04C2/38
Filed: 1981-09-29
Abstract: The insulating panel for walls, floors or ceilings comprises peripheral sections (110) which are assembled together to form a main frame. The main frame supports a secondary framework of vertical struts (140) and diagonal cross-members (130) which give the panel its rigidity.

Abstract: PCT No. PCT/FR82/00192 Sec. 371 Date Jun. 20, 1983 Sec. 102(e) Date Jun. 20, 1983 PCT Filed Nov. 17, 1982 PCT Pub. No. WO83/01755 PCT Pub. Date May 26, 1983.The procedure for manufacturing thin profiled strips, made up of continuous unidirectional fibers embedded in a thermoplastic resin, consists of impregnating a lap (1) of parallel fibers with resin particles, achieving resin fusion, forming the profiled strip and of cooling the latter. The lap (1) of fibers is dipped into a bath (26) of resin particles, mechanically impregnated with the particles, by feeding it for instance around rollers (15, 16, 17) immersed in the resin particles and the excess particles are removed to obtain the desired resin to fiber content ratio. Use of profiled strips obtained, in particular for outwardly reinforcing tubes or for producing moulded items.

Title: Excitation circuit for pulse laser - produces extra excitation pulse before main pulse to stabilise pulses
Inventor: SOLDATOV ANATOLY NIKOLAEVICH
IPC: H01S3/03
Filed: 1982-05-27
Abstract: The excitation circuit produces at least one extra excitation pulse before the main excitation pulse is applied to the gas discharge tube (1) and its amplitude and leading-edge slope are less than those of the main pulse and required to induce lasing at the temps. prevailing in the discharge tube. The extra excitation pulse may be produced either before or simultaneously with each main excitation pulse and its duration is given by a specified equation involving the actual and max. repetition frequencies of the main pulses. The advantage lies in stabilising the laser pulse energy when the repetition frequency is varied over a wide range.

Patent FR-2521437-A1 (FR)
Inventor: OBERLEITNER GERHARD
IPC: A63C9/088
Filed: 1983-02-11
Abstract: The invention relates to a jaw for a safety ski binding which can be released at will and when dangerous loading states are reached and has a pivotally mounted retaining device for firmly holding a ski boot by means of a piston which can be displaced in a cylinder, which cylinder forms a closed hydraulic system with a further cylinder, in which a further piston can be displaced, it being possible for the first piston to be subjected to pressure fluid by the further piston by a non-return valve which can be bridged by means of a solenoid or pressure-relief valve, and the activation of the solenoid valve being performed by a computer processing signals from force transducers. The invention is based on the technical problem of designing such a jaw for a safety ski binding in such a way that it can be fitted in its entirety on a ski and has the comfort usual in the case of safety ski bindings. This problem is solved by the retaining device being formed by a highly pivotable sole holder, and by the two pistons being arranged one above the other and parallel to the upper side of the ski, preferably in the housing of the jaw, of which pistons at least the upper piston, preferably both pistons, is, or are, supported on a control face of the sole holder, at least in the descent position of the jaw.

Title: Indium gallium arsenide fet - includes thin film of silicon nitride and has high transconductance
Inventor: CHO ALFRED YI
IPC: H01L27/12
Filed: 1983-02-16
Abstract: Field effect transistor contains semi-conducting regions of source, drain and canal all with the same type of conductivity but the source and drain regions more highly doped than the canal which is of In Ga As. The source and drain electrodes are in contact with the source and drain regions and the grid electrode is separated from the canal region by a thin layer of SiN. The canal region has a crystalline network coinciding with a semi-conducting layer of higher resistivity which in turn coincides with the network of a semi-insulating substrate of SiN of thickness 150 to 1000 microns. Useful in memories, signal treatment and microwave transmission. Transistors have a reduced grid leakage current and a high trans-conductance.
