Title: Time multiplex transmission system - involves method for synchronisation of timing generators in transmitter and receiver
Inventor: SCHENKEL KLAUS DIETER DR ING
IPC: H04J3/06
Filed: 1973-10-13
Abstract: The system synchronises time frames in the transmitter and receiver, with the frames represented by the spacing between periodically recurring frame synchronisation words; the frames are divided into n time slots in which signal blocks can be transmitted. Equidistant supporting pulses are inserted into the signal block in time slots; the receiver synchronises itself at first with these supporting pulses, and derives from them time slot synchronisation with the received signal train; then the receiver scans the frame slot-by-slot for the frame synchronisation word; the synchronism is reached after the frame word is p-times correctly recognised by the receiver; the spacing between supporting pulses is an integral multiple of the time slot duration, and the pulse is inserted between the end of one slot and the beginning of the next.

Title: Treatment of waste water from paint spray booths - with recycling of recovered water, using ultra-filtration
Inventor: DUERR HEINZ
IPC: B05B14/462
Filed: 1973-10-25
Abstract: Air extracted from paint spray booths is washed with water to remove paint particles. The resulting water/paint mixture passes to an ultrafiltration system which separates part of the water and enables it to be returned to the spray booth washing system. The conc. water/paint mixture is recycled through a collection tank with a cooling coil and on reaching a max. permissible concentration is pumped out for disposal. Method reduces spray booth water requirements. Little or no additive chemical are required for the separation.

Title: Safety device preventing pressure pulsing in turbo-compressor - switches pressure differential signal operational control to prevent stroke repetition
Inventor: PALMER JOHANNES
IPC: F04D27/02
Filed: 1974-02-15
Abstract: The device prevents repeated pressure pulsing. Two branch lines are connected with the pressure line of the compressor, each branch line communicating with a pressure vessel. One of the vessels is provided with a flow restriction. A differential pressure sensor is connected with the two vessels whose output signal is converted into an ohmic value acting on a resistance bridge circuit. The output of the bridge corresponds with the negative half-cycle of a pressure pulse, and is fed into a regulator with nano-second response. The regulator output is extended in time by a capacitor and acts on a switching device which triggers the action necessary to prevent repetition of the pressure pulse.

Title: Alarm for prevention and cure of bed-wetting - uses disposable draw-sheet retained over waterproof sheet and electrodes
Inventor: KENK GEB WIRTH INGRID
IPC: A61F5/48
Filed: 1974-05-31
Abstract: A child continent when awake out not when asleep is awakened from sleep when the moisture of incipient micturition completes an electric circuit to give him audible notice. Voluntary control returns as the child wakes, and he gradually learns to waken in time without electrical help. False alarms are given if the child's bare skin touches the electrodes, so an insulating draw sheet (6) is placed across, and held in position by press studs (2'). The whole equipment is held in the required position in the bed by tapes (4, 5) fastened to the bedstead. After each use the electrodes must be dried and covered by a fresh, dry drawsheet. To this end the draw sheets are absorbent and disposable.
