Title: Separation of organic refuse for recycling - uses water entering through perforated container bottom to remove buoyant organic waste
IPC: B03B9/06
Filed: 1975-12-18
Abstract: The household refuse is collected in containers fitted with perforated bottoms and flap valves. The refuse contains a certain amount of organic waste which is to be recovered for recycling. The container (2) has a raised bottom in relation to the lower rim of the container which rests on the floor. The procedure for reclaiming the organic waste involves placing the container into a water filled tank so that the container rim rests against the bottom of the tank. After opening valves fitted in the container bottom, the buoyant uplift of the water flushes out the organic matter to the surface of the container and as it spreads over the water level of the tank it is collected for recycling. The buoyant uplift can also be produced by connecting the container bottom to the discharge pipe system of a pump. The flushed-out parts float on the surface, surplus water is collected, cleaned and recirculated.

Title: Completely digital interpolation circuit - uses function generator which produces two clock frequencies to divide and multiply increments respectively
Inventor: PFEFFER JEAN-LOUIS DR
IPC: G06F17/17
Filed: 1976-05-03
Abstract: The completely digital interpolation circuit comprises a RAM holding the two ordinate values which are transferred one after the other to a buffer register (A, B) with a 20 ns delay. A three-stage, 4-Bit subtraction unit calculates the difference between the two registers and this is stored (C). Via a multiplexer (MUX) Bits 4 to 12 are transferred to an adder (AD1-R) and the difference increments produced by the clocking frequency (ZST), are multiplied. The second clocking frequency runs, for example, eight times faster. Bits 1 to 3 are routed to a comparator (COM) and with the aid of a counter (Z) driven from the clock frequency, the increments are eventually equalised with the difference between successive ordinates. In a second adder (AD2) the increments are added to or subtracted from the B register ordinates according to the sign of the difference. The interpolated values (INT) can be read out via a multiplexer to a D/A converter.
