Patent DE-3618223-A1 (DE)
Title: Industrial robot arrangement
Inventor: LINDHOLM CARL-HENRIK DIPL ING
IPC: B25J19/00
Filed: 1986-05-30
Abstract: Robot arrangement for a production line, which contains at least one robot of the oscillating type, the arm system (10, 14) of which is rotatable about at least one axis (12). The secondary arm (14) of the robot and a counterweight (16) are arranged displaceably on the primary arm (10) of the robot such that the centre of gravity of the arm system lies in or in the immediate vicinity of the axis of rotation (12), irrespective of the position of the secondary arm (14) and of the primary arm (10). To achieve this, the counterweight (16) and the secondary arm (14) are displaceably connected to one another by means of a rope (18) which runs round rope pulleys (20) at the ends of the primary arm (10). If a plurality of robots of this type are fixed to a supporting framework extending over the production line, the robots are fixed in pairs symmetrically to opposite side walls of the overhead part of the supporting framework. <IMAGE>

Title: Environmentally friendly aircraft
IPC: B64C39/06
Filed: 1986-07-14
Abstract: Noise injures the body. Everone who has to live at an airport can tell a sorry tale on this subject. This would be avoidable, as well as the enormous consumption of land and woodland if the aircraft were designed in a similar manner to a small airship without a gas filling and streamlined without wings. Instead of wings, round discs are intended to be used for horizontal flight, which discs rotate above the aircraft, driven by engines in the aircraft which likewise cause round discs of the same weight to rotate these and then transmit their rotation to the external discs by means of a common shaft. Vertically rotating discs complete the stabilisation of the aircraft. Air flaps are intended to be opened in the discs for landing and taking off, and it is intended that they can be opened manually for emergency landings. Additional flaps as wind traps are intended to cause the external discs to rotate during emergency landing as a result of the inclined descending flight. Tubes having a point at the front are intended to provide forward drive (propulsion) by rotation, air being intensively shovelled into the tubes through openings at the tip, by means of wind vanes and the rotation of the tubes.

Title: Method and device for aligning and fixing a semiconductor wafer on a support device
Inventor: HAEFELE EBERHARD
IPC: H01L21/00
Filed: 1986-09-18
Abstract: The invention describes a method and a device for aligning and fixing a semiconductor wafer (1) having regular structure line markings on a carrier device having a frame (4) which is provided with notches (3a, 3b) and across whose opening a film which is adhesive on one side is stretched. The wafer (1) is placed with its structural line side down on an alignment table (5) and brought into contact with alignment pins (6a, 6b), to fix its X and Y positions. A light beam from an optical system (7) is aimed through an opening in the alignment table (5) at a clearly defined structural line on the wafer (1) and then displaced parallel to the alignment table plane by a translational movement of the optical system (7). The clearly defined structure line is then again aligned with the light beam by rotating the wafer (1) within the alignment table plane relative to the optical system (7). The optical system (7) can then be returned by means of a translational movement with respect to the wafer and, if necessary, the wafer can again be aligned with the light beam by rotation. Finally, the carrier device is placed on the back of the wafer in this position and laminated to the wafer (1) by pressing the film. <IMAGE>

Title: Device for swivelling, rotating and rolling over a motor-vehicle body
Inventor: BABICH BERND
IPC: G09B9/04
Filed: 1987-02-03
Abstract: In a car driver's driving experience it can happen that his vehicle turns over in an accident and remains lying on the roof or on its side. The driver has not practised this situation and does not know how he can release his seatbelt without injury and leave the vehicle. Even assistants from the fire brigade and police etc. do not know how they can assist the driver who is still buckled-up in this event. The correct procedure in this situation can now be practised with the device according to the invention. The invention relates to a device with supports, with holding devices which are mounted rotatably in the latter and are intended for connection to the bumper supports of the vehicle body of a motor vehicle, and with a brake acting upon a holding device. The driver practising this situation gets into the vehicle body and buckles up. The vehicle body is then rotated and locked in the rotational position. In said position driver and assistants can practise the correct procedure.
Patent DE-3705567-A1 (DE)
Title: Pit-hauling machine
Inventor: LEHMANN GEORG DIPL ING
IPC: B66B15/04
Filed: 1987-02-21
Abstract: In a known pit-hauling machine designed as a friction-pulley machine, a motor is located within a friction pulley mounted on a stationary shaft, with the result that a space-saving construction is afforded. To simplify this construction, particularly with regard to the absorption and transmission of the forces occurring on the friction pulley (1) during operation, the latter is mounted on rolling bearings (5) located on its inner circumference (4), the stator (9) of the motor and the rolling bearings (5) being arranged on machine parts (10, 12) connected to a foundation on bearings (11). The distribution of the operating forces to bearings of very large diameter has a beneficial effect here, so that a stable construction is obtained at a low outlay, the balancing of the friction pulley (1) being appreciably simplified at the same time. <IMAGE>

Title: Device and measuring process for the contactless linear measurement of pipes or rods
Inventor: HELLMUND WOLFGANG DIPL ING
IPC: G01B11/02
Filed: 1987-02-20
Abstract: The invention relates to a device for the contactless linear measuring of pipes or rods with the aid of sensors which are arranged at least in the region of the pipe ends at fixed intervals laterally next to the pipe or rod and which sense the position of the pipe or rod, and with the aid of a displacement-measuring device for sensing the distance of the end of the pipe or rod from at least one of the sensors alongside it and also with the aid of a computer for processing the measured values and signals to give a measurement result. To provide a simple and robust device, the accuracy and measuring speed of which is not impaired by the masses to be measured, it is proposed that the sensors (5, 6) be arranged on a crossmember (3) which extends over the length of the longest pipe (1) or rod to be measured and can be moved parallel to the pipe or rod by a displacing distance which can be sensed by the displacement-measuring device and corresponding to the interval between two neighbouring sensors (5, 6). <IMAGE>
Patent DE-3706463-A1 (DE)
Title: Balanced optical receiver with automatic balancing
Inventor: PIETZSCH JOACHIM DR ING
IPC: H04B10/60
Filed: 1987-02-27
Abstract: In a balanced optical receiver for heterodyne or homodyne reception, the input part contains two series-connected photodiodes, at whose connection point the difference between the two photocurrents is tapped. The advantage of the balanced receiver is that, in the amplified differential signal, the components of the composite signal comprising received light and local laser light are added to one another due to the 180@ phase shift, whereas the DC components of the photocurrents and unwanted AC components produced by the intensity noise of the local laser cancel each other out. This requires perfect balance in the optical paths and in the photodiode response, for which it is advisable to use avalanche photodiodes. For balancing purposes, it is proposed to generate a correction voltage from the DC component of the differential current signal which is added to one avalanche photodiode and is subtracted from the other avalanche photodiodes in order to produce an effective bias voltage. <IMAGE>

Title: Hydraulic brake pressure control system - has spring plunger of larger diameter than pilot valve seat
Inventor: SANDAU HARTMUT DIPL ING
IPC: B60T13/16
Filed: 1987-05-09
Abstract: The hydraulic control system supplies the fluid from a pressure source via a flow control valve (16) to a vessel, a consumer unit or a brake cylinder (46) under control of a pedal unit (95,97). A current of control fluid tapped off from the control valve is throttled or interrupted, a brake pressure being generated in the control system. The latter also incorporates a spring-loaded plunger (77,84) and a pilot valve (49) whose plug (49A) is thrust against its seat (63) by pressure generated by the pedal. A small plunger (69) under the pressure in the brake cylinder acts on the plug in the opening direction, its diameter being smaller than that of the seat. When the pedal is operated, control fluid flow is throttled by the plug to an increasing degree, moving the control valve slide (15) into a position in which fluid flows to the cylinder. The diameter of the plunger (77) on which the spring (84) acts is greater than that of the valve seat (63). ADVANTAGE - Accurate control of pilot valve with consequent brake operation in small stages and no shock.

Patent DE-3735773-A1 (DE)
Inventor: RIEGER BENEDIKT
IPC: F41A17/64
Filed: 1987-10-22
Abstract: According to the invention, the gun has a cage (13) which is axially movable in the barrel direction and to which the release system, with the exception of the trigger lever (12), is fastened. Preferably, the cage is located inside a basic box (17), by means of which the extended cage axles (7, 11) are guided in long holes (18, 19). Two states can be set from the gunstock (30) by means of a cocking and uncocking system. In the safety position, the operative connection between the trigger lever (12) and the trigger-guard lever (6) is interrupted. In addition, a bolt (14) on the trigger-guard lever (6) is caught in a long hole (33) in the wall of the basic box (17). When a shot is fired, the striking piece (4) overcomes a detent (5) on the end of the catch lever (10), because the catch lever (10) can shift downwards. During loading or repeating, the striking piece (4) is retracted and the catch lever (10) is supported once again by the trigger-guard lever (6) (irrespective of whether the gun is cocked or uncocked). The safety slide (23) can be attached to the gunstock (30) in any position desired by the rifleman. The ideal position on the gunstock neck (30) enables him to operate the gun almost without thinking. But it is also possible to provide a resilient safety yoke (37) on the bottom of the gunstock; only when this safety yoke (37) is pressed against the gunstock with a trigger hand is the gun cocked. When the rifleman lets go of the weapon, the basic box (17) automatically shifts into the position of rest and the gun is automatically uncocked.

Title: Process for producing planar tubular heat exchangers and a constructed tubular heat exchanger
Inventor: MOECKEL JUERGEN DIPL ING
IPC: F28F9/18
Filed: 1987-12-19
Abstract: The invention relates to a production process for planar tubular heat exchangers and to a constructed tubular heat exchanger, which is suitable in particular for heat recovery from waste shower water produced in shower installations of sports and recreation centres, health service institutions and also military and industrial sanitary complexes. The aim is essentially to realise the tubular heat exchanger with an uncomplicated production procedure, minimal fabrication requirements and easily available materials, i.e. while simultaneously ensuring that hygiene requirements are met and classification features are improved. According to the invention, this aim is achieved by first of all combining the heat exchange tubes to form a tube bank, subsequently bringing together the end regions of this tube bank with a flow-distributor segment in each case and, following that, surrounding the end regions of the tube bank and also the distributor segments with a composite material. The tube bank, consisting of unalloyed or low-alloyed steels, and the flow-distributor segments are previously given a metallic corrosion-prevention coating. <IMAGE>

Title: Input processing circuit for an air-flow sensor
Inventor: SHIMIZU MEGUMU
IPC: F02D41/18
Filed: 1988-01-22
Abstract: The input processing circuit (2c) for an air-flow sensor (1) contains a differential amplifier which is connected to the air-flow sensor (1) via two leads (3a, 3b) and has an operational amplifier (2a). The circuit processes the output signal (VAFS) of the air-flow sensor (1) and delivers the result (VO) of the processing to an A/D converter, the output signal (VAFS) of the air-flow sensor being fed to the differential amplifier via a filter circuit, so that no errors arise because of various types of disturbance in the measurement of the quantity of air sucked in by an internal combustion engine. Connecting the inverting input of the differential amplifer via a resistor (R31) to earth avoids errors which are caused by interrupting a reference voltage lead between the air-flow sensor and the input processing circuit. Also avoided are errors which are generated by potential changes as a result of circuits connected to the supply current. <IMAGE>
