Patent FR-2318941-A1 (FR)
Title: Formation of a thin transparent oxide layer - on the face of a liquid-crystal cell, as electrode
IPC: C03C17/245
Filed: 1973-03-06
Abstract: The method comprises cathode sputtering of a metal target in an atmos. partically consisting of oxygen. The pressure in the sputtering chamber is controlled at a mean value P1 during formation of lower and intermediate layers on a substrate, and is increased to a mean value P2 during formation of the surface layer. The lower layer is a passivating oxide of stoichiometric compsn, the intermediate layer is an oxygen deficient oxide and the surface layer is a stoichiometric passivating oxide compsn. The method is used for the formation of transparent electrodes for liquid crystal rells. The surface layer of stoichromatric passivating oxide is impermeable to oxygen atoms from the air, hence, the non-stoichiometric layer exhibits a stable resistiorty. The passivation is effected simultaneously with the frowth of the oxide oxide layers.
Patent FR-2223605-A1 (FR)
Title: Water tap with pressure controlled membrane seal - has push button on-off control and adjustable flow
IPC: F16K7/14
Filed: 1973-03-30
Abstract: The tap body has three main parts, with a membrane between each pair of joint surfaces. When the circular hole in the middle portion communicates with the inlet pressure it presses the lower membrane against the valve seat beneath it and so prevents flow. Pressing the push-button mounted on top of the tap shuts off this central space from the inlet pressure and allows the water to drain through the tap outlet. Inlet pressure then opens the valve. The lift of the membrane can be adjusted to control the flow.

Title: P.C. Boards connector produced by punching rect. socket part - from metal strip, shaping then separating contact pin from strip
IPC: H01R13/432
Filed: 1973-05-15
Abstract: The printed circuit board connector consists of a long contact pin (3) of rectangular cross-section and a rectangular cross-section and a rectangular socket region between the two pins. The socket region is first punched out of a metal strip; the internal spring fingers (58, 59), which will eventually grip an external contact pin, are then pressed out of the socket region, and the sides of the socket are folded up to form a tube of rectangular cross-section. The contact pin is then punched from the strip and the complete connector is removed. The connector may have two coaxial contact pins and a single spring contact finger in the socket part.

Title: Television channel selector - used on network distribution system permits use of wide-band receivers
Inventor: MAUDUECH ROBERT
IPC: H04N7/10
Filed: 1974-06-26
Abstract: A selector for television signals distributed on a network system and interposed between the main transmission cable and the receiver has a variable-frequency band-pass filter, a transposing modulator, a fixed frequency band-pass filter (34) and an attenuator. Vision pass-band shaping occurs so that the vision carrier is attenuated to half amplitude whilst preserving the sound signal. The characteristics of the selector shape the response so that a wide-band receiver can accept the narrow-band selected signals. In addition, if the transposed channel is chosen in the 41-68 MHz Band, the filter is easy to manufacture.

Title: Assembly of tubular element structures - furniture and filing cabinet frames assembled by internal clips
IPC: A47B31/00
Filed: 1974-11-25

Both lower frames are fitted with castors to permit easy movement and it is envisaged that the lower sliding frame would carry baskets for supporting files. The various elements are connected together by plastic clips which fit around projections fixed to the frames at junction points. The projections and clips are shaped to prevent sliding when assembled and the clips themselves are hinged to permit easy assembly to the projections. When assembled, the clips are kept closed by the closely fitting tube of the other frame.

The gases to be treated are conditioned at two different times and in separate housings. They can be deliberately left rich in unburnt ingredients on extraction from the incinerator, and the conditioning chanber can be entirely accommodated inside the secondary combustion chamber, thus providing maximum heat for the other conditioning operations. Gas speed in the conditioning chamber can be greater than 50 metres per second.
Patent FR-2260212-A1 (FR)
Title: Control circuit for standby battery - uses differential amplifier to correctly load battery to improve service life
IPC: H02J9/06
Filed: 1975-01-13
Abstract: This circuit for floating or standby batteries detects the variation in load current which flows in two small resistances (R2, R3) forming one half of a Wheatstone bridge. These are connected between a rectified mains supply (5/6) and the load. The floating battery is connected to the mid-point of the two resistors. The other half of the bridge is formed by a variable resistance (R4/R5). Battery current flow maintains the balance of the bridge which is sensed by a differential amplifier that gates a mains control circuit (4). The battery is therefore able to work under load conditions that prolong its useful life.
