Patent DE-4121047-A1 (DE)
Title: Swing arm drive for robot - has both rope falls connected to same end of single accumulator spring
Inventor: PRZYKLENK KLAUS DR ING DR
IPC: F03G1/00
Filed: 1991-06-26
Abstract: The drive is for a swing arm in an industrial robot having a spring accumulator coupling to the arm via a rope reeved round a cylindrical surface on the arm so that it cannot slip. The accumulator aids driving torque at the beginning of the arm movement, and forms a brake near the end. The accumulator (16) contains a single spring (18), and both falls (32, 40) of the rope (20) are coupled to the same end of the spring. The rope is so dimensioned that the spring assumes a position giving minimum pre-loading when the arm is halfway through its movement. There can be a tension roller (46, 48) for each rope fall, holding the rope tight against the cylindrical surface (30). ADVANTAGE - Simplicity and compact construction.

Title: Neutral tasting tablets and granules contg. Mesna - contain binder, disintegrating agent, lubricant filler and opt. effervescent mixt.
Inventor: SAUERBIER DIETER
IPC: A61K9/50
Filed: 1991-07-04
Abstract: Tablets contg. mesna as the active ingredient and opt. conventinal flavourings, sweeteners and perfumes also contain per pt. wt. mesna, 0.01-1 pts. wt. of a binder, 0.03-0.4 pts. wt. of a disintegrating agent, 0.01-0.2 pts .wt. of a lubricant, 0.1-1 pts. of a lubricant 0.1-1 pts. wt. of a filler and, in the case of effervescent tablets, an additional 0.05-30 pts. wt. of a conventional physiologically acceptable effervescent mixt. USE/ADVANTAGE - Mesna is used to protect the urinary tract in the therapy of tumour diseases using ifosfamide. Mesna is also used as a mucolytic. Mesna is a white hygroscopic powder with a characteristic taste and is very sensitive to oxidn. and, on contact with oxygen, esp. in damp atmos. rapidly turns into dimesna. The invention overcomes previous problems in formulating mesna or a mixt. of i-PrOH and water and the granulate can then be worked up to give tablets or coated tablets which have good chemical stability, are easy to take and, when immediately swallowed are practically neutral in taste.

Patent DE-4141616-A1 (DE)
Inventor: STEEG HEINZ BERND DR ING
IPC: B29C65/06
Filed: 1991-12-17
Abstract: A process is disclosed for securing a holding part in a recess of a prefabricated part having a core made of thermoplastic material having a plurality of cavities, for example with a cellular or honeycombed structure. The holding part, which is essentially designed as a solid of rotation made of thermoplastic material, is pressed on the prefabricated part and rotated at such a speed in relation to the prefabricated part that the material of both parts heats up until melting at the contact surfaces between the holding part and the prefabricated part. As the material of the prefabricated part melts more quickly than the material of the holding part, a recess with axially extending contact surfaces is formed in the prefabricated part, into which the holding part enters, bonding over its contact surfaces to the prefabricated part after it stops to rotate.

Filed: 1992-04-14
Abstract: In an automatic iris adjusting apparatus a picture is divided into a predetermined number of areas according to the size of an object and the brightness of the background, a video signal level corresponding to a divided area which is selected 24 according to a user's selective key input is averaged 15, and the iris is adjusted 32 by the difference 31 between the average value and a reference level. The automatic iris adjusting apparatus digitally processes luminance signals from a CCD pickup 1, divides it into a predetermined number of areas, selects 24 a specific area among the divided areas and generates horizontal and vertical window pulses. The apparatus comprises a signal switching section 13 for selectively switching a video signal corresponding to the selected divisional area among the picked-up video signals in response to the window pulses. Accordingly, the apparatus averages the selected video signal levels and generates an iris driving signal and compares it with a reference level, thereby controlling the drive of an iris adjustment motor. <IMAGE>

Title: Absolute position sensor, esp. for vehicle throttle flap angle - has incremental sensors generating counting pulses and direction information from periodic markings, and uses other markings to produce serial signal containing absolute position information
Inventor: GOEHRING FRANK
IPC: G01B7/30

Title: High resolution computer controlled image projector - uses computer controlled active and passive opto-electronic displays with fixed shutter focussing light onto thin light fibres
Inventor: FOSS PIERRE NICOLAS DR MED
IPC: G09F9/305
Filed: 1992-06-15
Abstract: The arrangement is for high resolution computer controlled colour image projection using computer controlled active and passive opto-electronic displays (17). A fixed shutter (3) with or without integral lenses (2) is positioned between the display and a light receiving wall (4). The shutter focusses the light signals from display elements (1) onto the inlet apertures (15) of thin light conducting fibres (5, 14). These fibres guide their light signals to a light outlet wall (10) which has very thin mixed colour light conducting cables (9, 11). ADVANTAGE - Different display technology can be used to improve resolution and brilliance of pictures through glass optic. Adaptable for all image projectors. Fibre optic cable use allows light receiving  units to be arranged in compact form.

Inventor: LUKIC BORIS
IPC: D04B15/78
Filed: 1992-08-03
Abstract: In a textile machine, in particular in a knitting machine, with controllable working elements (3) and an arrangement for selecting the working elements, the working elements (3) are held in their initial position by a holding magnet (8) and are selectively released from their initial position by an electromagnetic control system (12, 13). In order to obtain a textile machine with a simple design, capable of being driven at high working speeds but in a reliable and safe manner, at least one holding magnet (8) is rigidly fixed to the part of the textile machine that carries the working elements (3). A direct contact between the working elements (3) and the moving control system (12 or 13) is thus avoided, so that a contactless selection of the working elements (3) is made possible.

Abstract: A displacement vibration damper, consisting of a primary mass secured to a piston-engine crankshaft to be damped and a secondary mass connected to the primary mass, is fitted with means which ensure the best possible sprung coupling and effective hydrodynamic damping combined with compact construction. The sprung coupling is made using preferably laminated bow springs (15) having a radial shoulder (3) on each side forming part of the primary mass and flexibly interconnecting the primary and secondary masses. The shoulder (3) merges on the outside radially into a peripheral belt (5) which has displacement vanes (7) on its outer periphery, or said vanes (7) are fitted directly to the outer periphery of the shoulder (3). With relative rotation between the primary and secondary masses, the displacement vanes act to provide hydrodynamic vibration damping within function chambers (37) which are formed radially inside an outer ring (13) enclosing the vibration damper at the outer periphery, between the outer periphery of the belt (5) or axial extensions of angle rings (9) and between the sides (slots 33) of sections (35) extending axially from lateral discs (11).
