Title: Liquid filtration apparatus
Inventor: ALEXANDER ROBERT OSTEEN
IPC: B01D21/00
Filed: 1980-05-30
Abstract: Liquid filtration apparatus for machine tool-coolant comprises a liquid collecting tank (10) with a rotary drum filter and an endless chain drag conveyor (15) located in it. The drum is mounted between a pair of sprockets (23 and 24) round which the conveyor chains extend so as to be enclosed within the volume of the conveyor and rotated by the conveyor drive motor. The drum comprises an inner perforated steel layer and an outer layer (33) of woven metal mesh. A row of liquid jet nozzles (44) within the drum direct liquid jets at the inner surface of the cylindrical wall, to wash off solids separated by the mesh from liquid flowing into the drum.

Title: Vacuum flush toilet arrangement for aircraft
IPC: E03F1/00
Filed: 1980-07-18
Abstract: A non-recirculating vacuum- operated flush toilet for aircraft comprises a bowl (22) with electronically controlled water supply (12), and flush valve (20). Actuation of a switch (11a) operates a solenoid (17) which allows fresh water to flow under pressure from a tank (15a) to the toilet bowl (22). The control module (11) next sequences the flush valve by energizing a solenoid (32) which raises a clapper valve (34) and connects the chamber (35) to a vacuum accumulator (3) and this causes a diaphragm valve (26) of the flush valve assembly to move to an open position to allow communication between a vacuum holding tank (14) and the toilet bowl (22) by way of a drain (24). Waste material and flush water is thus sucked through the drain to the tank (14). Thereafter the valve (26) closes ready for a new flushing cycle. The system has a manual override handle (69) and is protected against fire. <IMAGE>

Patent GB-2104755-A (GB)
Title: System for recording scrambled digital signals and playback system therefor
Inventor: MASUDA ISAO
IPC: G11B20/10
Filed: 1982-07-30
Abstract: A digital signal derived from an analogue signal(s) 1-4 is organized into a sequence of frame signals each comprising digital words of information and frame synchronization. A digital scrambling word of a predetermined bit pattern is generated by a data scrambler 12 for each of the frame signals at the termination of the frame synchronization work and is modulo-2 added to the information word to randomize each frame signal. The randomized signal is frequency modulated and is recorded. Upon reproduction, the recorded signal is frequency demodulated to recover the scrambled frame signal from which clock pulses are regenerated and the frame synchronization word is detected. A data de-scrambler (32) is provided to generate a digital de- scrambling word when there is a phase match between the detected frame sync and the clock signal. The de-scrambling word is modulo-2 added with the scrambled information word to recover the original signal. The randomizing frequency-shifts the recorded signal to prevent interference with tracking signals on the record and also results in better self-clocking properties. <IMAGE>
