Patent FR-2312700-A1 (FR)
Title: Pressure relief valve for electro-chemical cell - has ball retained by plastics cap which deforms to release gas
Inventor: COUEILLE DANIEL
IPC: F16K24/04
Filed: 1975-05-30
Abstract: The electro-chemical cell is contained in a cylindrical housing (1) with a projection (2) forming the positive terminal. The negative electrode (4) is separated from the housing (1) by a cap (6) of resilient plastics with a spherical recess for a stainless steel ball (7). The resilient cap (6) is pressed firmly against the ball surface and seals off the hole (11). When the pressure inside the cell rises, the cap (6) is deformed so that a gap appears between cap and ball allowing the gases to escape through the hole (11) into grooves (12, 8). To prevent escape of traces of electrolyte from the housing (1), the grooves may be filled with material to absorb the electrolyte.
Patent FR-2320798-A1 (FR)
Title: Cold forming machine for spline - has rotating angle rollers which deform thin ring to force radial blade punches into part
Inventor: POULLAIN JEAN
IPC: B21J7/14
Filed: 1975-08-11
Abstract: The machine has several blade punches (1), equal to the number of splines, spaced radially around the part (2). These punches have their outer edges at an angle and fit into a holder (3) which permits radial movement. A thin cone shaped ring (9) is placed over the punches, forming a cage. This is centred between one or more pairs of rollers (11), angled to match punches and ring. The distance between the rollers is less than the ring diameter. As the rollers rotate and move axially, the ring is deformed. This forces the blade punches into the part, cold forming the splines or serrations.

Title: Sorting flat bars of different types e.g. of warp stop motion - by providing each type with different aperture and inserting rod (OE150576)
IPC: D03J1/14
Filed: 1976-02-11
Abstract: Flat bars of different types, e.g. the bars of a warp stop motion of a loom are all provided with apertures, the aperture of each type of bar having different dimensions. A rod is inserted through the apertures of a gp. of bars and is rotated the cross-section of the rod and the separation of the side walls of the apertures in one type of bar being such that when the rod is rotated the bars of this type rotate with it, so that the bars of this type are sorted out from the gp. A second bar of different cross section may then be inserted into the apertures and rotated to sort out a second type of bar from the gp. The bars can be easily sorted out into their different types.

The top of the sleeve (5) may be spring dowelled into a sealed (7) casing cap (8) which serves as the control knob.
Patent FR-2305996-A1 (FR)
Inventor: KUBELKA AXEL
IPC: A63C9/00
Filed: 1976-03-30
Abstract: An improvement in a ski binding arrangement wherein a ski boot is secured to a sole plate which in turn is releasably secured to a ski. The ski boot is pivotally secured by a front support to the sole plate and the heel of the ski boot is releasably secured to the sole plate. The ski boot is comprised of two parts, an upper leg part which is pivotally secured about a horizontal axis relative to the lower boot part. The heel holding assembly serves to lock the upper part of the ski boot to the lower part of the ski boot when the skier is using the ski boot in a downhill skiing environment. A movement of the heel holding assembly to a non-use or cross-country skiing position will facilitate a relative movement between the upper leg portion of the ski boot and the lower boot part.

Title: Apparatus checking filling level in transparent pipes - has optical switching device which consisting of optical transmitter and receivers on either side of pipe
IPC: G01F23/292
Filed: 1976-05-06
Abstract: The pipe (5) to be checked has on it two light barriers (1, 3 and 2, 4) which each consist of an optical transmitter (1, 2) and an optical receiver (3, 4) positioned underneath one another. The two light barriers can be operated alternately and the two receiving signals are linked to one another. The receivers are interrogated as regards their d.c. signal and a.c. signal. The d.c. signal is intended to be used to check the filling level of the pipe, while the a.c. signals indicate a fault. The beams (6, 7) generated by the two optical transmitters are directed through the pipe offset radially in relation to the centre by the distance (9).

Title: Treating effluent high in organic matter esp. from olive oil mfr. - by neutralising, passing through bacterial bed then aerating
Inventor: BEBIN JEAN
IPC: C02F3/12
Filed: 1976-07-13
Abstract: Biological purificn. of liquids or residual liquors which are very organically polluted is described.

Title: Ejector for load carried under aircraft - has delayed action charge fired by inertia of sliding weight to retract telescopic sections
IPC: F42B3/00
Filed: 1976-12-22
Abstract: The ejector is fitted to an aircraft to launch a load carried underneath.

Title: Recording and displaying system for biological electrical potentials - uses electrodes applied to e.g. thorax, multiplexer sampler, D=A converter, computer, memory and memory display
Inventor: COURT LOUIS
IPC: G01R13/00
Filed: 1977-04-15
Abstract: The system records and displays variable analogue signals emanating from a number of points in a matrix. For each point in the matrix there is a measuring system having a signal detector and an amplifying circuit. A multiplexer sampler provides a clock time rate of successive groups of signal samples emanating from the various detectors. An analogue digital convertor receives the signals from the multiplexer. A digital computer fitted with a rapid access memory has buffer zones which receive data from the converter. A circulation memory with direct access to the rapid access memory successively stores the data emitted by the converter. The system has means of displaying the memories contents. The computer and the memories being designed to permit, at different times, selection of data from a single detector and restoration of the variation in the signal time from the detector.
