Title: Continuous digester for organic waste to produce methane etc. - advances waste through up=and=down passages to leave via liq. seal
Inventor: CARTIER GUY JEAN-LOUIS
IPC: C12N5/02
Filed: 1980-08-19
Abstract: The installation comprises a vertical digestion chamber which has a vertical partition extending from the base of the chamber to terminate well clear of the top of the chamber. The partition thus separates first and second vertical passages which communicate via a space above the partition. Waste is fed periodically into a charging port at the lower end of the first passage. A fermentation is started in the waste which rises to fill the first passage and overflow the top edge of the partition. Anaerobic fermentation continues in overflowing waste which progressively fills the second passage, to be evacuated as required via a discharge port at the lower end of the second passage. Waste has to pass through a liq. seal to leave the discharge port which is always submerged. The installation is used to produce a combustible gas by anaerobic fermentation of organic waste. Partic. stable litter and manure. The operation is continuous but the waste can be retained until fully fermented. A high proportion of straw etc. can be accepted with no danger of blockage. There is no problem of surface crust formation. The plant is simple, inexpensive and of compact construction.

Title: Vacuum type connector for PCB and test appts. - uses sheet glued onto frame forming cover placed around circuit
Inventor: DAHAN ALFRED
IPC: G01R1/073
Filed: 1980-09-12
Abstract: The device ensures an air-tight connection between an electronic circuit and its test appts. where the latter uses a vacuum chamber to press the circuit against itself. A frame has a sheet fixed to it, forming with it a cover. During the test, this cover protects the electronic circuit and presses the frame onto the appts. The sheet is glued to the edge and on one of the faces of the frame. When a vacuum is obtained in the test chamber, one is also created via holes in the connecting device. The frame is made of plastics. In one form, the device may be equipped with hinges which are connected to the test appts. The hinges ensure that perfect positioning can be obtained during connection, and eliminates the need for positional adjustments.

Title: Async. electric motor with ducted ventilation - uses disc formed into duct to carry air radially outwards around stator winding of motor
Inventor: BRESSON ROGER
IPC: H02K9/06
Filed: 1980-09-26
Abstract: The electric asynchronous motor has a rotor mounted on a shaft. The stator core surrounds the rotor and the stator poles carry a stator winding. Cooling air is drawn through holes in the end plate. The mouth of the ventilator duct surrounds the rotor shaft and draws air horizontally into the duct. The duct curves through ninety degrees so the air is directed radially outward and brought out underneath the stator winding. The air flows round the stator windings and exhausts through holes in the motor casing. A channeling device is provided for the air entering the casing via the two ventilation openings. This allows the ventilator inputs to be bought in closer to the motor axis.

Title: Horizontal cylindrical digester to produce methane from organic waste - in baskets which can be changed without interrupting gas prodn.
IPC: C12M1/113
Filed: 1981-03-23
Abstract: The upper part of the vessel has at least one inlet for liq., while the lower part of the vessel contains a horizontal perforated floor extending the length of the vessel and below which liq. is collected.

Title: Computer based musical score writing system - uses light pen and TV screen to construct score on screen for generation by synthesiser
Inventor: WILLAEYS DIDIER
IPC: G09B15/04
Filed: 1981-06-09
Abstract: The musical score writing system uses a TV screen in order to construct the score for a piece of music. The system includes a basic memory containing the different musical symbols, and either a keyboard, or a light pen so as to be able to choose a symbol. A musical memory is provided to store the symbols forming the score, and a character memory is used to generate the musical symbols on the screen. A synthesiser is able to reproduce the music as it is stored in the musical memory, so that the composer may hear what he has written. Internal testing circuits check the music as it is written to ensure that it does correspond with the conventional rules for writing music. If the light pen is used, then a menu of possible characters is provided on the screen for the composer to choose from.

Title: Brake for crankshaft with high moment of inertia - uses counter to compare actual and demand positions of crankshaft to operate brake valve
Inventor: CROGUENNEC JEAN
IPC: G01L5/28
Filed: 1981-08-06
Abstract: A crankshaft is driven by a motor through a clutch brake assembly, controlled through an electropneumatic valve. The valve is controlled by an end of travel circuit which ensures that the crankshaft stops at the TDC position. A second control for the valve is an emergency cutout assembly which applies the brake to the crankshaft. A disc on the end of the crankshaft has radial transparent sectors to signal to the nearest degree using a photocell assembly. This drives a counter controlling a relay on its contacts in the valve supply circuit. The relay is operated when the counter has counted a number of pulses which are equal to a prerecorded number in a memory. The number of pulses counted is indicated on a display. A dynamic amplifier maintains the relay circuit closed until the crankshaft rotation slows down in the braking process.
