Title: Spinning frame - has a conveyor band at each side of the frame, with transfer facilities at each end
Inventor: BRUNK NORBERT DR
IPC: B65H67/06
Filed: 1992-03-17
Abstract: On a spinning machine, conveyor bands are arranged at each side along the working positions to supply tubes and remove cops. There is a transfer grip arrangement, so that the cops or tubes can be lifted from one of the conveyor bands, and placed on the other. The frame (1) has a series of spinning positions at each side. A conveyor band (9) moves in direction (A) at one side of the frame. If full cops (16) have been doffed automatically, they travel to the end (11) when the arm (26) lifts them one at a time on to the returning band (10) in direction (B). The arm (26) has a centre (27) to swivel (F,G) from one side to the other and back again. The movements are synchronised to the movements at the transfer end (12), where full cops are lifted to outward transport, and tubes set on the band (9). The drive for the arm (26) is by connection to a crank, driven by a motor which operates in steps. ADVANTAGE - There is a saving of space at the end of the frame, as the bands do not need to continue round.

Patent DE-4217259-A1 (DE)
Inventor: VOGT RICHARD
IPC: F04B23/12
Filed: 1992-05-25
Abstract: The invention relates to a double pump consisting of a radial piston pump (1) and a vane-cell pump (2). The double pump is to be simplified in such a way that its overall length is reduced and there is only one casing separation. The radial piston pump (1) has a ring insert (8) fitted in an aperture (5) in the casing (4) with a moulded face plate to seal a pump set (20, 21, 22) of the vane-cell pump (2). One frontal surface (23) of the face plate belonging to the ring insert (8) together with the casing (1) also forms a dividing seam between the two pumps (1 and 2). Only one annular seal (35) is needed to seal the dividing seam.

Title: Water flow decontamination - using slits in sediment of ground water outflow filled with a sorption agent to take=up water-soluble sorbable hazardous matter
Inventor: STEFFEN HEINZ DR ING
IPC: C02F1/28
Filed: 1992-06-27
Abstract: To remove sorbable water-soluble hazardous matter from outflowing ground water sediment, which contaminates the water flow, a slit is formed in the sediment which is packed with a sorption agent suitable for the material in the sediment. The agent is held in the slit until it reaches satn. with the hazardous matter. Pref. a further slit is made in the sediment, after th first slit in the direction of water flow, and is filled with the sorption agent when the first slit packing is satd., and so on. Where the agent is satd., it is removed and replaced with fresh agent. A group of pref. three slits is made in the direction of water flow, to be filled with sorption agent. The slits are formed with narrow walls to be filled with the agent, using steel profiles and the like to shape the slits, or trench diggers. USE/ADVANTAGE - The method is for situations where the sediment of outflowing ground water is contaminated by organic or inorganic matter such as hydrocarbons, heavy metals and the like. The sediment is easily worked where the water environment is in danger of contamination, with an effective cleaning action, without affecting the water supply.

Title: Automatic control for motor vehicle friction clutch - monitors vehicle speed and direction and provides engine braking without stalling
Inventor: REIS KARSTEN DIPL ING
IPC: F16H59/46
Filed: 1992-09-01
Abstract: The friction clutch (3) is operated by a servo drive (15) via a processor control (17). This operates th clutch w.r.t the engine condition and the vehicle speed etc.. The control has two reference engine speeds; one below idling speed and one above. the lower level is used to release the clutch to prevent stalling while the higher level is used as an engine braking control e.g. on inclines. The higher speed can be used to provide controlled engine braking if the vehicle rolls against the set gear direction, with the throttle pedal at idling. This allows the driver to move the vehicle in and out of spaces on an incline with a minimum of gear changes. The lower reference speed is 100 to 300 rpm below normal idling speed while the higher level is 50 to 500 rpm above idling. The exact levels are determined w.r.t engine/vehicle conditions. ADVANTAGE - Improved drive control, less risk of engine stalling.

Title: Electronically controlled lock operating system - has active key transmitting pre-programmed code via fibre-optic conductors for stepping motor latch release and manual unlocking
Inventor: SCHREIBER HANS DR MED DR MED
IPC: G07C9/00
Filed: 1992-10-12
Abstract: The system uses an active key (208) which is pre-programmed by a separate programming module (200) in known fashion via an inbuilt opto-coupler (214,215), microprocessor (210) and battery (211). A signal button (212) on the key (208) transmits the code to the lock during a limited time (239) via the lock's internal fibre-optics. On recognition of the code a miniature 180 deg. stepping motor (220) operates an eccentric cam (227) to release a sliding latch (223) which at all other times prevents rotation of the bolt in the lock cylinder. The lock is then operated manually by the key (208) which can only be inserted/withdrawn when in a neutral orientation to ensure resetting of the latch (223). USE/ADVANTAGE - Minimises battery load by limiting transmission time and using watch-type stepping motor for latch release. Enables matched series of individual codes to be stored in external programmer with convenient master key facility.
