Patent DE-4100838-A1 (DE)
Title: Speed-compensated stacking level controller for sheet printer - introduces delay proportional to printing speed into clocking level measurements unless stack is being raised
Inventor: WINDISCH ARMIN DR ING
IPC: B65H1/14
Filed: 1991-01-14
Abstract: The stack-raising motor (15) is switched on and off by separate circuits (5,16) feeding power amplifiers (13,14) via OR gates (11,12). Output from a level detector (1) is AND-gated (2) with that of a measurement clock pulse generator (3) connected to a paper/cardboard thickness selector (8) and a status memory (30). The clock generator (3) includes a gate circuit linked to a counter and a rotational speed comparator. The clocking is delayed (18,19) in dependence on speed by a number of clock periods, suppressed while the motor (15) is running with the memory (30) set to zero. ADVANTAGE - Stack height is compensated for rotational speed and sheet thickness even when the print run is interrupted.

Title: Benfotiamine-contg. pharmaceutical for topical use - is for treating e.g. rheumatic disorders, sciatica, lumbago, migraine etc. and other disorders beneficially affected by vitamin=B
Inventor: WOERWAG FRITZ DR
IPC: A61K31/675
Filed: 1991-03-27
Abstract: A pharmaceutical contg. Benfotiamin has the Benfotiamin taken up in and distributed throughout a carrier and is applied topically to the skin. USE/ADVANTAGE - The pharmaceutical can be used to treat rheumatic disorders, general joint and muscle pains, root irritant syndrome of the spinal column, HWS-syndrome, shoulder-arm-syndrome, symptoms resulting from polyarthritis, tennis elbow, stiff neck, lumbago, sciatica, disc pain, arthroses, polyneuropathy, neuritis, migraines, neuralgia, shingles, facial paralysis. Benfotiamin is a lipid soluble analogue of vitamin B1. By applying it topically to the body parts affected, where it is then converted into thiamin or cocarboxylase, it is possible to achieve targetted local action. As the transport route is shorter than that when applied in the form of e.g., dragees, less thiamine is produced before the Benfotiamin reaches the affected part of the body and the cells to be treated, thus the action due to thiamine is maximised
Patent DE-4113339-A1 (DE)
Title: Open end rotor spinning unit - applies liq. feed directly to yarn as it leaves rotor
Inventor: SCHNEIDER KLAUS
IPC: B65H71/00
Filed: 1991-04-24
Abstract: An appts. is added to an open-end rotary spinning unit to provide liq. to the newly spun yarn. The appts. is positioned between the output and the cross winding creel. The feed may be applied directly before or indirectly at the take-up roller pair. Pref. the open-end spinning rotor unit has sliver input with action of the opening roller to release separate fibres. Suction through the tube allows fibre to be laid in the groove of the rotor and yarn is withdrawn along the exit tube. A take-up roller pair is spring loaded, and the yarn is transported to the cross winding unit to form a cheese. Distilled water or other fluid in a container with lid and air hole, has a stop tap, with gravity feed tube ending in a capillary tube of the correct dimension to ensure adequate flow, when the fluid is being removed by the surface of the take-up roller, and which is then applied to the yarn. ADVANTAGE - The feed is by gravity, and so no pump or bath for the roller is required. The capillary tube prevents unwanted drips.

Patent DE-4119874-A1 (DE)
Inventor: HERING HUBERT DIPL ING
IPC: F16D25/063
Filed: 1991-06-17
Abstract: A description is given of a pressure actuated friction disc clutch which is closed by spring force and opened by the pressure of a pressure medium, the space containing the clutch discs (26, 30) being designed as an essentially sealed chamber (52), the radially inner region of which can be connected to a pressure source in order to release the clutch. In order to permit cooling of the clutch discs when the clutch discs slip due to an overload with the clutch engaged, a radially outer region of the chamber (52) is connected to a pressure-medium reservoir via a valve arrangement. The valve arrangement (82) is designed and arranged in such a way that it is controlled by the pressure of the pressure medium prevailing in the chamber (52). In particular, the valve arrangement (82) closes a connection between the chamber (52) and the pressure-medium reservoir if the clutch discs (26, 30) have been separated by the pressure prevailing in the chamber (53).

IPC: F04D29/54
Filed: 1991-08-16
Abstract: The invention concerns an air-flow duct for an axial-flow air fan (100), in particular a fan for ventilating or extracting air from the film-exposure chamber of a recorder. The fan has a motor-driven hub (10), a rotor (11) fixed to the hub and a duct (12) surrounding the rotor (11) about it longitudinal axis, as well as preferably parallel support flanges (13a, 13b) with air-flow apertures (14, 15) located at each end of the duct, the flanges having elastic or elastically mounted attachment elements (18). In order to design a fan of this kind which provides external protection, at least one air-flow side, against, in particular, the interfering effects of exposure to daylight, without suffering high power losses, it is proposed that a multiplicity of angled metal fins (17) are mounted next to, above or below each other on at least one flange (13b) at a distance apart which will prevent direct access by light in the longitudinal direction.

Title: Half carcass conformation determn. -  by image processing using chine as datum point
Inventor: EGER HORST DIPL ING
IPC: A22B5/00
Filed: 1991-09-19
Abstract: The examination of slaughtered animal (esp. pig) body halves uses image processing hardware and software to determine the outer contour, flat layer and meat/back fat ratio. The hardware is used to produce recordings of the body halves with the spines and all intervertebral layers. The chime is used at the starting fixed point for determining parameters for the stripping and classification. The chine and other vertebrae are determined by object analysis according to predefined contour and object parameters. Determn. of the chine and other vertebrae is effected pref. by iterative search in the image section with increasing grey value level. Position of the located vertebrae and of the intervertebral layers is used to determine the meat cutting parameters, while the position of the vertebrae, the outer contour and the fat layer are used to determine fat and meat amounts for classification. ADVANTAGE - Process allows determn. of accurate cutting position parameter, classification of the meat content in the loin region and of the fat thickness, and exact morphological examination.

Title: Servo operated lock for vehicle boot - has servo drive only into open position with mechanical sprung action lock closure
Inventor: WIPFLER ALFRED
IPC: E05B81/24
Filed: 1992-07-02
Abstract: The lock linkage is released by a lever (13) pushed into the open position by a drive block (14) operated by a spindle drive servo. In the open position the servo drive is released nad a return spring returns the spindle drive and drive block, leaving the lever in the open position. The lock catch levers are open and are dropped into the closed position when the boot lid is closed. This pushes the lever back to the closed position. The servo action is monitored by a microswitch (12) which provides a warning light on the dashboard to indicate that the boot is open. The switch is reset when the lock is closed. A simple two wire connection controls the lock action, or a two wire system with a ground return. ADVANTAGE - Simple servo drive, minimum of wiring connections.
