Patent FR-2164455-A1 (FR)
Title: Heating glass sheets - prior to convex bending
IPC: C03B29/08
Filed: 1971-12-21
Abstract: A sheet or a stack of two or more sheets of glass, is heated for producing convex bending, by the continuous passage of the sheet or stack of sheets on a roller conveyor into a furnace where it is heated before being introduced into a forming chamber. The speed of the rollers of the conveyor supporting the sheet or stack of sheets is modified during its introduction into and discharge out of the furnace, in such a way as to cause the time of passage through the furnace of the leading part of the sheet or the stack of sheets to be changed w.r.t. the trailing part and thus obtain a temp. difference between the leading and trailing parts, such that at the instant of convex bending, the sheet or stack of sheets has a uniform temp.

Patent FR-2133746-A1 (FR)
Title: Insulated gate fet - with n type silicon grid
IPC: H01L29/00
Filed: 1972-04-14
Abstract: A P type substrate with N type source and sink regions and an intermediate channel over which a thin insulation film is deposited, has over that channel a grid of polycrystalline, phosphorus doped, N type Si so that an inverted mode N channel transistor is formed. An alternative is to use N type substrate with P type source and sink regions forming an inverted mode P channel transistor. Two similar transistors in a common substrate of which one has a phosphorus doped N type grid and the other a boron doped P type grid form a complementary pair of one N channel inverted mode and one N channel direct mode. These can be used as a signal inverter. Relatively cheap compared to ion implantation.

Patent FR-2190487-A1 (FR)
IPC: A63C9/085
Filed: 1972-07-03
Abstract: The device comprises a bridge member formed in two portions, a first portion fixed with respect to the ski and a second mobile portion articulated with respect to the first portion; the second mobile portion co-operates with a member fixed to one extremity of the boot by a first system of ramps, one of which is fixed to the second portion while the other is fixed to the boot, and with the first portion fixed to the ski by at least one second system of ramps, one of which is fixed to the second portion and the other to the first portion. A first spring system of a holding device is located at the other extremity of the boot and urges the second portion downwards towards the ski by the effect of the ramps; at least one of each system of ramps is inclined so as to form an acute angle with the ski, the acute angle being open towards the holding member of the other extremity of said boot. The invention solves the problem of putting on skis when the skier's boot soles have collected considerable quantities of packed snow and permits the safety release action to operate under these conditions.

Title: Frequency modulated preset fine tuning - involves micrometer controlled wheatstone bridge potentiometer
IPC: H03J5/02
Filed: 1973-07-24
Abstract: FM fine tuning, particularly for pre-set operation, allows a simple high precision arrangement for picking out individual transmitting stations and uses a slide wire type potentiometer having a highly geared down manual micrometer control feeding a galvanometer giving a zero reading for optimum tuning. The gearing of the potentiometer cursor permits simple fine tuning. Such a potentiometer is provided for each frequency band and provides the final setting position with a locking device. The galvanometer itself forms part of a wheatstone bridge made up of high input impendance FETs. The slider movement rides over a threaded bush leading to a manually operated micrometer screw.
Patent FR-2242121-A1 (FR)
Title: Ski binding for downhill and cross country - torsion controlled heel catch and front hinged sole plate
IPC: A63C9/00
Filed: 1973-08-29
Abstract: The step-in type of safety binding has a spring controlled heel retainer which together with a toe clamp holds the boot to the ski until displacing forces exceed the preset limit. The boot support is held to the heel by a further latch. The heel retainer can be opened to release the sole support so that the whole boot can rotate about a transverse horizontal axis in front of the toe cap while being retained on the sole support by the spring controlled bindings. This arrangement allows the binding to be used for normal downhill use as well as for long distance touring where the heel is required to be free to lift.

Title: Device to measure distance and speed of berthing vessel - determines difference frequency between transmitted and reflected signals
Inventor: TOMASI JEAN-PIERRE
IPC: G01S13/34
Filed: 1974-10-22
Abstract: The distance and speed of approach of a vessel (1) approaching a berth (2) along an axis (x-y) are determined by radiating a microwave signal from an antenna (7). The signal is obtained from an oscillator (3) which is modulated (5) and then multiplied (4). A duplexer mixer stage (6) determines the difference frequency between transmitted and received signals which is applied to a control loop comprising amplifier (8) and frequency measuring stage (9) coupled to the modulator (5) to maintain constant the difference frequency. A conversion circuit (11) determines the distance measurement (12) while a differentiator (14) enables speed to be indicated (15).

Title: Logarithmic periodic aerial for receiving two frequencies - is fitted with H.F. dipoles contained in insulated housing
IPC: H01Q11/10
Filed: 1975-03-05
Abstract: The aerial is intended for receiving television signals in the VHF and UHF bands. The dipoles of the high frequency aerial, and the associated parallel conductors of the their lead, are enclosed in a housing of insulating material. This protects the aerial from the weather and oscillations caused by wind turbulence which can introduce distortion by setting up vibrations sufficient to affect the phasing of the signals. The low frequency dipole loop can be fixed to the housing and is thereby also given greater stability. The end of the assembly has a clamp which is used for fastening it to an upright supporting member.
Patent FR-2305589-A1 (FR)
Title: Four stroke engine valve drive - with timing variation achieved by changing eccentricity of three link system driving cam shaft
IPC: F02D13/02
Filed: 1975-03-27
Abstract: The engine cam shaft drive is transmitted from the cam shaft to a crank which is connected by an intermediate lever to a second crank mounted on the cam shaft. The angle between these cranks can be varied by a mechanism which connects the intermediate lever to a point on a rotating member eccentric to the cam shaft. Changing the degree of eccentricity between crankshaft and rotating member changes the angle between the cranks and so changes the valve timing.
