Patent FR-2507500-A1 (FR)
Title: Rotary agitator - aerator partic for prodn. of metabolites etc. - using rotor contg. air compressing piston reciprocated by eccentric
Inventor: EYSMOND EDOUARD
IPC: F04B27/053
Filed: 1981-06-12
Abstract: The rotor is mounted on a motor-driven shaft. As the rotor turns it draws in external air via a passage through the shaft, compresses the air and then diffuses it into the agitated liq. in the vessel. Pref. the rotor contains a cylindrical chamber in which a piston is reciprocated by shaft rotation. The piston is reciprocated by an eccentric rigidly fixed to the shaft. The eccentric has a cutout extending from the air inlet passage to the circumference of the eccentric over a substantial arc. The cutout rotates to communicate alternately with axial air discharge passage through opposite ends of the piston. As the piston reciprocates, its retreating face sucks air into the cylinder via shaft passage and cutout; its advancing face expels air from the other end of the cylinder via a valved outlet nozzle. The axis of the eccentric is pref. offset from the parallel axis of the drive shaft by a distance equal to half the dia. of the drive shaft. The installation is esp. employed in the mfr. of metabolites such as enzymes or organic acids such as citric, by aerobic fermentation of a liq. nutrient inoculated with suitable microorganisms. It is also applicable to the purificn. of waste water. Aeration takes place at the point of most intense agitation. Aeration is automatically proportional to the rate of agitation. No separate compressor is required to inject the air.
Patent FR-2510306-A1 (FR)
Title: Tube for TV camera with charge sensitive targets - has supplementary cathode and associated heating filament juxtaposed with main cathode for scanning between lines
Inventor: FAVREAU MICHEL
IPC: H01J31/38
Filed: 1981-07-21
Abstract: The tube is applicable to television camera tubes designed for 625 line operation but run on 312.5 line systems. The design removes the problem of local build-up of potential in the inter-line spaces in the target. The camera tube is a glass cylinder with a thin metallic layer constituting the signal plate and a photoconducting layer deposited on top of it. The electron beam is focussed by a shaped electrode of cylindrical form and two externally mounted concentric coils. A fine mesh, situated at the end of the focussing electrode, causes the electrons to slow down and to strike the target normally. The electron gun has two cathodes and two heating filaments. Either a single filament, or both can be switched on. The filaments are juxtaposed so that, in conjunction with the geometry of the beam optics, the target can either by fully scanned and/or simply have the principal lines scanned as in a 312.5 line system.
Patent FR-2511560-A1 (FR)
Title: Amplifier circuit for high impedance measuring instrument probe - has slightly less than unity positive gain amplifier with FET input stage and bipolar transistor output
Inventor: RUSZNYAK ANDREAS
IPC: H03F3/50
Filed: 1981-08-11
Abstract: A probe has an electrode (6) connected to the gate of an FET (15) acting as a source follower with a load resistor (20) for a second transistor (17) stage. These transistors have a current source (18) comprising an FET or bipolar transistor. The emitter of the second transistor is connected to an amplifier (19) comprising a bipolar transistor (25) whose polarity is inverted w.r.t. the second transistor and which is connected as an emitter follower. The emitter is connected through a zener diode (26) to the output (8) and to the load resistor for the input stage. A resistor (27) assisting in defining the stage gain connects the zener diode to the power supply and to the collector of the second transistor stage. A capacitor (28) across the zener improves the high frequency response of the circuit.
Patent FR-2512228-A1 (FR)
Title: Electronic neurological electrical signal analyser - stores responses to stimulation to obtain product of optimised signals of each channel to obtain maximas between each minima pair
Inventor: HOURI ANDRE
IPC: G06F19/00
Filed: 1981-08-25
Abstract: Two electrodes are applied to adjacent points on a scalp in the sensory activity area. The low level signals are amplified and filtered. An A/D converter and sampling circuit provides digital values at equal time instances after each stimulus. A memory, stores digital signal values which occur in large numbers separated by short time intervals. The values at corresponding time intervals after each stimulus are summed to improve the signal to noise ratio. The digital values are optimised and passed to D/A converters for each channel. The two analogue signals are multiplied together and applied to a maximum and minimum detector. The resultant output is divided into sections defined by minimum values, the maximum values in each section are determined and displayed for analysis.
Patent FR-2512964-A1 (FR)
Title: Unijunction transistor circuit for detecting weak magnetic field - comprises transistor without metallic case and, insulated from ambient light and operating as negative resistance oscillator
Inventor: KAMARINOS GEORGES
IPC: G01R33/06
Filed: 1981-09-14
Abstract: A unijunction transistor (1) of the double base diode type is formed without the metallic cover and has been mounted on a plexiglass support. This transistor acts as the magnetic field sensor when the field is applied transversely w.r.t. the semiconductor bar. A capacitor (2) is mounted in parallel between the emitter (E) and the first base (B1). A resistor (3) is connected to the end of the capacitor (A) connected to the emitter while its other end is connected to a polarising power supply (5) for the emitter and base circuit. A second polarising supply (6) is connected to the two base circuits to control the emitter current and frequency of oscillation characteristic. It also permits accentuation of the negative resistance characteristic to adjust its sensitivity.

Title: Pressurising pump for terpsray - has membrane operated by means of incompressible fluid
Inventor: JACQUEMOND JEAN
IPC: F04B43/00
Filed: 1982-04-06
Abstract: The spray circuit consists of a membrane pump supplying water to a spray lance with a venturi inductor to induce the required amount of cleaning fluid. The circuit is equipped with an automatic bypass and a pressure regulating, manual bypass. The membrane (30) of the pump of the circuit separates the fluid chamber (34), for the spray water, from the working chamber (31).
