Patent DE-3033214-A1 (DE)
Title: Programmed timer with independent switching devices - uses cam operated independently by timer to tilt microswitch for alternative switching
Inventor: RAST JUERGEN
IPC: H01H43/12
Filed: 1980-09-01
Abstract: The switching system, controlled by a programmed device, includes a microswitch operated by a switching arm with its bottom end resting against the microswitch and its top end controlled by a disc rotated by a timing mechanism. The microswitch can also be operated independently by a second mechanism driven from another part of the timing mechanism. The microswitch is mounted so that it can be tilted, and an arm which can be swung against its diagonally opposite corner, carries a rotary cam. This is driven by a wheel in mesh with a wheel forming the second part of the timing mechanism drive. The cam thus causes the microswitch to tilt to operate in the alternative manner.

Title: Adjustable beam recording appts. - reflects beams by rotatable polygon mirror for imaging on photosensitive drum via optical system
Inventor: KITAMURA TAKASHI
IPC: H04N1/04
Filed: 1980-09-10
Abstract: Facsimile reproducing appts. uses laterally-aligned beams (la,Lb,Lc) the line of alignment being at a small angle (theta) to the direction of scan. This angle may be varied, thereby varying the line pitch (P), when a high resolution scan is required. The beams are scanned over the surface of a drum, the angle (theta) being controlled by passing the fixed b3ams through an optical rotator on the beam producing device e.g. a semiconductor laser chip - which may be physically rotated. The beams are modulated via respective delays to take account of the differing positions of the beams in the direction of scan.

Patent DE-3045888-A1 (DE)
Title: Proportional control hydraulic brakes - include manual override control to increase rear brake force
Inventor: BURCKHARDT MANFRED DR ING
IPC: B60T11/20
Filed: 1980-12-05
Abstract: The normal braking control uses a double master brake cylinder with the rear brake pressure reduced w.r.t. increasing front brake pressure in order to maintain stability. A second master cylinder operated manually increases the rear brake force so that an experienced driver can obtain braking on good grip surfaces. The second master cylinder has its input linked to the rear brake output from the main cylinder, and in normal operation just transmits the braking force. Application of e.g. a hand brake lever, operates the second cylinder and enhances the rear brake force. The driver is also able to control rear skids for performance cornering.

Patent DE-3132168-A1 (DE)
Inventor: PETER KLAUS-JUERGEN
IPC: G01S5/16
Filed: 1981-08-14
Abstract: Circuit for evaluating the signals from several photodetectors (1a and 1b). Such an evaluation circuit is for example used for determining the position of a point on a ballistic curve inside a measurement plane. The signals of the photodetectors are scanned in rapid succession, whereby these signals are tansformed by an A/D converter (5) into digital signals. The evaluation circuit described contains a delayed-action system for delaying the digital signals by in particular two scanning cycles. Furthermore, a comparison system is provided to compare the signals of the same photodetectors at a time interval of one or several scanning cycles. Depending on the difference in the compared signals a logic signal is emitted in the form of 0 or 1. This avoids external interference from affecting the evaluation or determination of the position of a point.
Patent DE-3136668-A1 (DE)
Title: Method and working system for the preparation and execution of the mechanical treatment of areas used for agricultural purposes
Inventor: ANHEUSER RUDOLF PETER
IPC: A01B39/16
Filed: 1981-09-16
Abstract: In the mechanical treatment of areas used for agricultural purposes, motor vehicles, with the appliances mounted on them, or tractors, which pull these appliances, are used. The motor vehicle and tractor determine the minimum spacing of the seedling rows, do not allow exact straight guidance and, because of their high weight, presuppose a sufficiently dry soil, so that the tilled structure is not destroyed. These disadvantages are overcome in that, according to the invention, rails are laid parallel to the seedling rows, in such a way that one or more seedling rows run between the rails. A gantry-like appliance carrier carrying the working appliances is moved in or on a respective pair of rails and is displaced after the treatment of the respective seedlings. According to the invention, the various operations are carried out simultaneously, without a sufficiently dried soil being necessary for the travel of the appliance carrier. The invention also relates to the design of the appliance carrier and to the design and anchoring of the rails. <IMAGE>

Title: Floating screed and method for its production
Inventor: FEIST ARTUS
IPC: E04F15/12
Filed: 1981-09-26
Abstract: The invention relates to a floating screed for applying to concrete floors. It is intended to receive the heating pipes of a floor heating system, to be particularly thin and very firm. For this purpose, the welded wire meshes inserted into the cement/sand/gravel mixture are dimensioned thicker than in the prior art, and adjacent welded wire meshes are firmly connected to one another. The particle size of the gravel must not exceed 8 mm. A plastic emulsion which is introduced increases the adhesion between screed and welded wire meshes. After applying the welded wire meshes and the screed mixture, the former are set in horizontal oscillations by means of a vibrator. The screed mixture is thereby levelled and compacted.
Patent DE-3145317-A1 (DE)
Title: Door hinge for domestic appliances
Inventor: KOHLES DIETER
IPC: E05D15/56
Filed: 1981-11-14
Abstract: The door hinge intended especially for built-in appliances having a door (3, 4) which can swing open downwards causes the door first to be raised and then to be lowered during the opening operation. If, in a floor-standing appliance, a cover panel (8) is equipped with a decorative plate arranged under the door provided with a decorative frame (6) and decorative plate, the hinge prevents the bottom edge (28) of the door or of the decorative plate from abutting against the top edge of the cover panel when the door is being opened or closed. If, in a built-under appliance constructed with the same rinsing-vessel bottom tub (2) and the same inner door (4) and fully integrateable into the kitchen furniture front, an undivided decorative plate (5) projecting beyond the bottom edge of the door into the plinth region is fastened fixedly to the door, the same hinge makes it possible to open and close the door, whilst the bottom edge of the decorative plate can pivot into the plinth space without obstruction. A door-hinge lever (9) carries a rigid control segment (18) which has a circular track (19), a claw (20) and a journal (22) equipped with a rotatable roller (21). The claw is movable about a pin (23) and the roller is movable on a curved track (24) of a bearing block (10). At an opening angle of approximately 45 DEG , a pin (29) supports the door-hinge lever via the circular track. Located on a claw part is a pin (30) carrying a crank (31) which is rotatable about the pin (23) projecting through the claw. <IMAGE>

Title: Air/water heat exchanger, preferably for heat exchange at low temperatures, preferably for obtaining environmental heat for heat pumps
Inventor: HOELTER HEINZ DIPL ING
IPC: F28D9/04
Filed: 1981-12-05
Abstract: The invention relates to an air/water heat exchanger, preferably for heat exchange at low temperatures and for obtaining environmental heat for heat pumps. In order to avoid dropping below the dew point, and thus to avoid the attendant formation of ice, in the low temperature range during heat exchange - cooling of the air -, it is proposed according to the invention to produce the heat exchanger from a material whose K value is between 0.1 and 0.2 kcal/m, the incoming-flow velocity being above 2 m/sec. Because of the air streaming past, the sublimation power is greater than the icing rate on the heat exchanger. An ethylene copolymerisate is preferred as the material. The heat exchanger surfaces are preferably elastically deformable and arranged opposite one another in a planar and/or spiral fashion.

Title: Method and device for treating spot-like zones, especially defects, in material webs
Inventor: SJOEBERG PER
IPC: D06H3/10
Filed: 1981-12-30
Abstract: A method and a device for treating spot-like zones, especially defects, in material webs or strips of material of this type during a working process are to be improved in such a way that the defects can easily be detected and, above all, fixed, without the working process having to be interrupted thereby. This is carried out in that the spot-like zones (2) are assigned marking plates (10, 10a) preprepared so as to be finish-proof and having metal inlays (11), these marking plates being so connected to the material web (1) that the metal inlay spans a respective spot-like zone. The connection of the marking plate (10, 10a) to the material web (1) is to be made by means of an adhesive layer which is activated ultrasonically. The marking plate (10) according to the invention is equipped with a carrier disc (11) made of flexible and finish-proof material and with a metal inlay (12) which is covered with an adhesive layer (14) on the surface of the carrier disc confronting it. <IMAGE>
Patent DE-3203576-A1 (DE)
Title: Special microwave incident radiation II
Inventor: FRITZ KARL DR
IPC: H05B6/80
Filed: 1982-02-03
Abstract: The invention once again relates to energy concentration by interference in the interior of the object. However, while in previous applications the radiation was incident into the object more or less at right angles to the object surface, it has unexpectedly been found experimentally that energy concentration is possible in the interior, even in the case of precisely oblique incidence, without detriment to the penetration depth. This is particularly conspicuous in the case of elongated objects, or in the case of objects which are arranged one behind the other on a strip. Part of the radiation running out of the main beam which runs parallel to the surface clearly penetrates, at the most favourable incidence angle, into the interior until the energy in the main beam is consumed. The examples show oblique incidence with straight-line movement of the beam and object, with a beam rotating about an object moving in a straight line, and with an object rotating under a straight-line beam.

Title: Method and apparatus for producing metallic container bodies open on both sides and having a longitudinal seam welded by laser beam
Inventor: HAGEN WERNER DR ING
IPC: B23K26/262
Filed: 1982-02-20
Abstract: In this method of producing container bodies open on both sides, a sheet is bent in a tubular shape while forming an overlap at its marginal areas and is welded by a laser beam (L, LS) directed towards the overlap, which sheet is initially cut before the bending except for a small residual width (br). The residual connection is completely cut after the welding by a further laser beam (LT) acting in cycles. The further laser beam can either be taken directly from the laser source (29) or can be diverted from the welding beam (LS) by a semipermeable mirror (32). The apparatus for carrying out this method consists of a forming device (3) for bending the sheet and a welding arrangement (4) with a welding arm (19) which concentrates the laser beam (LS) intended for the welding on a focussed spot (34) in the overlapping area of the sheet. The further laser beam (LT) intended for the residual cutting-through of the initially cut material can be projected in cycles onto the residual connection of the sheet in a gyratory manner by an asymmetric rotating mirror (43).   <IMAGE>
