Title: Motor operated headlamp position adjusting drive - has hand-operated position selector switch and amplifier-controlled motor feed
Inventor: BAUER PETER-JOSEF
IPC: B60Q1/076
Filed: 1980-05-07
Abstract: Each headlamp (1,2) is provided with an independent motor drive (3,4). The mechanical linkage (5) between motor and lamp also moves a switch (10,11). The manually operated position selector (24) has two separate contacts (22,23). One connected to the battery (18) positive potential and the other to earth. These sliding contacts bridge fixed contacts (d7,c7',c7,b7,a7) in such a manner that when one slider (22) uncovers one pair of contacts (b7) the other slider (23) covers one pair (a7). If the manual selector (24) is moved to a new position a potential is applied to the relevant fixed contacts (8,9) of the motor driven switches (10,11). At the same time the potential is applied to the inverting input of the amplifier (14,15) associated with each motor. The motors then run until their attached moving contact reaches a potential free position.

Title: Contactless checking of pulse signals for breakdown detection - utilises inductive sensor with integration and rectifier circuits driving bistable with LED output indicator
Inventor: YAKOVLEV NIKOLAI IVANOVIC
IPC: G01R19/14
Filed: 1980-12-29
Abstract: Signal pulses are applied to an inductive sensor (1) which provides an input signal to an ac amplifier (2). An integrator circuit (5) slows the leading edges of the pulses while a differentiator circuit (6), comprising an amplifier (9) and a transformer (10), produces a train of pulses of short duration at the same frequency as the output of the inductive sensor. A full wave rectifier (3) produces a series of unidirectional pulses which are amplified in an ac amplifier (14). The amplifier output passes via a capacitor (17) to a bistable (15). If the bistable input exceeds a threshold value the output changes state to illuminate an LED (18). The LED (18) is extinguished and the bistable reset by a reset signal at its second input (19).

Title: Insulating element
Inventor: NAHR HELMAR DR DR
IPC: E06B3/267
Filed: 1981-01-27
Abstract: A heat-insulating profile element comprising two profile parts which are connected to each other by connecting webs. The connecting webs consist of heat-insulating material and engage, by means of anchoring elements, into undercut grooves on the profile parts. The profile parts and the connecting webs enclose a cavity which is filled by an expanding filling composition which subjects the connecting webs to tensile loading. In order to ensure that the elements are held together, even in the event of a fire, the anchoring elements are to be flexurally rigid and to consist of fire-resistant material. Furthermore, they should be connected to one another by a coil consisting of fibres which likewise consist of fire-resistant material.

Title: Oscillating pane as an anti-theft means
Inventor: SCHMIDT HEINZ
IPC: E06B5/11
Filed: 1981-08-17
Abstract: The invention for which a patent has been applied relates to an oscillating pane (1) as an anti-theft means which consists of non-breakable material and is fitted, by means of a movable foot fastening produces by hinges (3), behind the actual front pane (4), e.g. display-window pane, such that it is inclined forwards. The upper end of this pane is held at rest via elastic or oscillating elements, e.g. tension springs (2). If the first, fixed front pane (4) is then broken by force, the oscillating pane (1), which has not been broken, then prevents access to the objects (5) displayed behind it. Owing to its elastic upper fastening and movable lower fastening, the pane is capable of absorbing any resulting kinetic energy by its free oscillation and almost completely diminishing the effect of said energy. Even a number of effects of such energy resulting from the use of force can cause virtually no damage to the pane. Even if the oscillating pane is partially broken, it is virtually impossible to gain access to the objects lying behind it without a long time delay since, owing to its movability, the pane offers no fixed hold. The accompanying drawing depicts the overall arrangement of the oscillating pane in the installed state. <IMAGE>

Title: Frame for securing a wheelchair-bound passenger in a vehicle
Inventor: FEUTLINSKE HILMAR
IPC: A61G3/08
Filed: 1981-08-24
Abstract: A frame for securing a wheelchair-bound passenger in a vehicle, which is either fixedly mounted or movable in the vehicle and can be locked to the vehicle floor, is only sufficiently stable to take up the forces generated during an accident if the stability of the wheelchair is used as well. As the stability of the wheelchair must also be used to take up the forces, the frame can correspondingly have a lighter and more space-saving design. The elements for connecting the frame to the wheelchair are arranged in such a way that they interact with the side parts of the wheelchair which are situated on both sides of and close to the front edge of the seat.

Title: Power supply for a temporary connection of electrical loads
Inventor: FRIEDEMANN MICHAEL
IPC: H01R4/24
Filed: 1981-11-28
Abstract: Temporary electrical power supplies are used especially in the building trade. Until now, in large buildings having a large number of floors, power distribution boxes with a multiplicity of plug sockets have been provided to which electrical loads (worktools, lamps, etc.) are connected via conductor cables of greater or lesser length; the number of loads which can be connected is limited by the number of plug sockets. A temporary power supply is provided by the invention, which can be installed easily and quickly and can supply virtually any desired number of widely distributed loads, without long supply leads. This is achieved by means of a flexible multi-conductor cable of great length, contact devices provided for the loads being placed on the sheath of the cable, with power pick-off pins, which penetrate the sheating, for the cable conductors, so that an electrical connection is produced between the cable conductors and the loads. <IMAGE>

IPC: H05K3/00
Filed: 1982-01-15
Abstract: Method of printing printed circuit boards with a conductor track pattern, a solder resist pattern and/or a servicing aid pattern employing a known printing device. The printing device has a rubber stamp (Tampon), which is pressed onto a printing block wetted with ink. The printing pattern is then transferred to the printed circuit board. The ink is composed of a material which cures on exposure to UV radiation. This makes it possible to produce substantially more accurate and narrow-toleranced conductor patterns, and at the same time the production of the boards is substantially less expensive than for conventional methods having comparable precision.

Title: Sack filter row
Inventor: SJAELIN KJELL-ERIK
IPC: B01D46/06
Filed: 1982-01-25
Abstract: A device is described in a sack filter having at least one row of essentially vertically arranged filter sacks, each filter sack (1, 2, 3) being closed at its lower end and connected at its upper end to an air supply by means of a casing (6) which extends into the end of the sack, and a support (7) is inserted into each sack to keep it open. The object of the invention is to create a simplified device of this type. According to the invention, the filter sacks (1, 2, 3) are produced in a row from two webs of filter material (11), the webs being joined together by seams (9, 10) or the like to delimit individual sacks (1, 2, 3). The seams (10) between the sacks (1, 2, 3) run straight and proceed without interruption from one end of the sack to the other. Each sack (1, 2, 3) is arranged in such a manner that it is held by its upper end on the associated casing (6), that the filter material (11) is clamped between the casing (6) and a holding device (8, 14, 15), which surrounds the casing along the greater part of its periphery and is so arranged that the filter material between two neighbouring casings remains uninfluenced. <IMAGE>

Title: Panel advertising hoarding for alternating advertising, with a movably arranged frame for exerting contact pressure on the poster edges
Inventor: REMMERS HANS-JOACHIM
IPC: G09F13/04
Filed: 1982-02-17
Abstract: The large-area advertising spaces to be encountered in urban areas are pasted with new advertising posters every ten days. A movably arranged frame encloses the poster edge (Fig. 1), and consists of four individual frame parts (2, 3, 4, 5) (Fig. 2). The frame parts can be pivoted out of the plane of the base surface (1) by means of hinges and simultaneously lift off from the base surface. The outer poster edge is thus exposed, so that a new poster can be pasted on. After the pasting has taken place, the frame parts, which are resiliently mounted, are again pressed back to the centre of the poster and, by means of the frame section lug (9), lock onto the peripheral poster edge, which is thus pressed against the base surface and prevents detachment of the poster edges. On the underside of the frame section lug are fixing aids such as rubber corrugations, sharp elevations or the like. <IMAGE>

Title: Process and apparatus for separating environmentally harmful gases from exhaust gases from combustion plants
Inventor: BAER EDMUND DIPL ING DR ING
IPC: B01D53/34
Filed: 1982-05-22
Abstract: The process and the apparatus serve to separate environmentally harmful gases from exhaust gases and combustion plants in a reactor using a reagent solution of water and water-soluble absorbents with simultaneous removal of solid constituents of the exhaust gas in the same reactor. The water of the reagent solution is both solvent for the absorbent and also separating agent for the solid constituents of the exhaust gas; it evaporates virtually completely in the reactor. The exhaust gas leaving the reactor has a temperature above the water dew point temperature and is free of water droplets. It is likewise substantially free of solids and - with a suitable choice of absorbents - likewise substantially free of environmentally harmful gases, vapours and liquid constituents. The reaction products from the absorption can be reacted in the reactor with other gases and solids still contained in the exhaust gas, or with gases, liquids and solids also added to the reactor, to give utilisable cleaning residues. These can be discharged from the reactor as a dry powder.
