Title: Tubular solar heat collector for air heating - contains permeable fabric light absorbing layer through which air flows
Inventor: BOETTCHER ALFRED PROF DR
IPC: F24S10/70
Filed: 1980-10-11
Abstract: Tubular solar air collector consists of three or more superimposed flexible layers, including one of permeable fabric and others of plastics. The fabric layer is light- absorbing and the air enters the passage between it and an outer, transparent plastics foil and leaves the device in the channel between the fabric layer and the plastics foil next below it. In one variant, the lower plastics foil is highly light- absorbing, whereas in another variant, there is a metallic high reflecting layer between the fabric and the lower plastics foil layer. The air is heated up with exceedingly good heat transfer between the fabric and the air. High flow rates are not necessary and consequently higher air outlet temperatures can be achieved.

Title: Switching circuit for switching through cable TV and radio programs - has numerous switches each comprising two or more series diodes
Inventor: MACHT GERHARD DIPL ING
IPC: H03K17/76
Filed: 1980-12-03
Abstract: The switching circuit has an HF switch associated with each incoming line. Each HF switch consists of at least two series-coupled diodes (D) whose junction is earthed via a capacitor (C). Each switch is controlled by a divided voltage obtained from a two-resistor voltage divider (R11, R12...) assigned to that switch. All the voltage dividers are grounded at one end and connected at the other to a shared control line. The connections between related diodes are realised using microstrip lines. The advantage lies in fewer components and switches and in achieving high decoupling between programme lines and between input and output.

Patent DE-3105164-A1 (DE)
Title: Process for pressing and curing mouldings
Inventor: KISS GUENTER H
IPC: B27N7/00
Filed: 1981-02-10
Abstract: A process for pressing and completely curing mouldings, such as are used, for example, as the interior lining of motor cars, is described. In this process, the starting materials are preferably cellulose and/or lignocellulose fibre materials which - provided with binders - are pressed to form the desired mouldings. The pressing of the flat fleece-like raw materials is carried out according to the present process in such a manner that mouldings are produced whose density is less than 0.9 and is preferably in a range from 0.5 to 0.8 g/cm<3>, whereupon the mouldings are then subjected to post-treatment providing their final characteristics such as flexural strength, fracture strength, water absorption and the like, by supplying additional binder components externally to the pressed mouldings. The supplying of additional binder components is not carried out by a coating process to form a surface coating, but rather in the present process uses diffusion processes in which additional binders penetrate deeply into the pressed mouldings.

Patent DE-3111743-A1 (DE)
Title: Transmitting and receiving device for optical radiation
Inventor: DECKER RAINER DR RER NAT
IPC: G02B6/42
Filed: 1981-03-25
Abstract: In a transmitting and receiving device for optical radiation, e.g. for distance measurement, firing simulation or the like, at least one transmitting element and at least one receiving element are coupled into the beam path of an optical system by means of optical fibres which are connected to the transmitting and receiving elements and which are combined to form an integrator member whose end face is coupled to the optical system. The result is that the transmitted radiation passes virtually without loss into the beam path of the optical system, while a proportion of the received radiation which corresponds to the cross-sectional ratio between the corresponding optical fibre and the integrator member reaches the receiving element. Given the use of at least two transmitting elements and an integrator member whose length is not sufficient for complete equalisation of the light flux over the cross-section, it is also possible to determine the offset angle of a reflecting target from the optical axis of the optical system.

Patent DE-3118905-A1 (DE)
Title: Grinding attachment for a gear-grinding machine
Inventor: ULRICH HANS-JOACHIM DIPL ING
IPC: B23F23/12
Filed: 1981-05-13
Abstract: The invention relates to a grinding attachment for a gear-grinding machine, which preferably works by generation grinding with indexing control, in which the grinding body, swung in in the tooth direction, performs the stroke movement. The purpose of the invention is to increase the cutting capacity of the gear-grinding machine with the same or improved workpiece quality through a significant increase in the efficiency and rigidity of the grinding attachment. The object of the invention is to create a grinding attachment in which the acting cutting forces are transmitted over the shortest route to the tool carrier, the distance between the bearings (determining the running accuracy) and the grinding body is minimised, and displacements which result from the suspension of the grinding attachment at the tool carrier and the stroke movement are restricted mainly to the stroke direction. According to the invention, this is achieved in that an axial bearing and a radial bearing with minimal difference in diameter are arranged between grinding-body mounting and axial fastening surface of the spindle body, and the position of the grinding body on the grinding-wheel mounting relative to the axis of rotation is determined by axially flexible centring and an axial interface, lying perpendicularly to the axis of rotation, between axial bearing and grinding body. Field of application of the invention is machine tools, preferably gear-grinding machines and, to a limited extent, thread-grinding machines. <IMAGE>

Patent DE-3147269-A1 (DE)
Title: Device for simultaneous heating and cooling
Inventor: EIGNER OTTO
IPC: F25B9/00
Filed: 1981-11-28
Abstract: In the device according to the invention, to save energy in the warmer season, the heat exchanger (7) is bypassed and thus the high-pressure air is conveyed directly to the expansion chamber of the piston expansion machine and likewise, after pressure relief in the expansion chamber, the low-pressure air is conveyed directly to the compressor (1). The low-pressure air, which in this connection is only preheated in the regenerator, requires lower compression, as a result of which, in the warmer season, one of the two drive motors is switched off, while in winter operation both drive motors are used. <IMAGE>
Patent DE-3147323-A1 (DE)
Title: Process for the preparation of styrene
Inventor: FREY WALTER DIPL ING DR
IPC: C07C5/333
Filed: 1981-11-28

Patent DE-3148372-A1 (DE)
Title: Automatic fishing rod
Inventor: SAVIC SERGIJE
IPC: A01K91/10
Filed: 1981-12-07
Abstract: The invention relates to an automatic fishing rod for fishing for all types of fish. It is intended to free the angler from long periods of waiting, since the automatic rod activates independently when fish bite. The automatic fishing rod achieves this object because the base of the automatic fishing rod contains a spring which, after the fish have bitten on the fishing bait in the water, activates independently, and then the rod support (5) with the rod device (7) moves from the starting position to the end position, and the caught fish moves rapidly out of the water together with the fishing line. Previously, the rod support (5) and the rod device (7) must be pushed forward until the helical ring tensioner engages in the trigger hole (automatic fishing rod in operation); this is the starting position. When the fish bites, the automatic fishing rod activates (automatic system triggered), this leads to the end position, and the rod support and the rod device return into the starting position. <IMAGE>

Patent DE-3202755-A1 (DE)
Title: Carcass clamp
Inventor: OTT ROLAND
IPC: B30B15/06
Filed: 1982-01-28
Abstract: To be able to adjust a carcass clamp continuously to the carcass sizes possible within the intended range and to be able to carry out this adjustment quickly and preferably automatically, at least the adjustable cheek plates (2, 4) are constructed in the manner of interlocking lath grids, the laths (8, 9) of the horizontal cheek plate (2) being arranged laterally offset by the lath width with respect to those of the vertical cheek plate (4). It is thus possible for these two adjustable cheek plates (2 and 4) to intersect. On the other hand, however, a good support over the entire area of the carcass parts is possible. Since the cheek plates can be displaced individually and independently of one another, they are well suited to a motor drive. <IMAGE>

Title: Device for actuating a closing cylinder of a plastic injection-moulding machine
Inventor: LEUTNER VOLKMAR DIPL ING
IPC: B29C45/67
Filed: 1982-06-25
Abstract: The device for controlling a closing cylinder (20) of a plastic injection-moulding machine has a control circuit with a proportional regulating valve (25), with a pressure-reducing valve (13) and with a pressure governor (62) assigned to this. The position and speed of the closing cylinder (20) is entered as an actual value in a variable-gain amplifier (55), the desired value of which comes from a machine control (M). The amount of difference adjusts the proportional valve (25) according to a quantity of pressure medium required for the closing cylinder (20). The necessary desired pressure for the pressure-regulating valve (62) is composed of a constant pressure fraction (PK) and of a variable pressure fraction (Pv) from a memory (73) and is fed to the pressure governor by way of a summing amplifier. The variable fraction (Pv) comes from the memory. There, the latter is respectively corrected in relation to the memory content by the substraction or addition of an increment, depending on whether the proportional valve has in the preceding cycle opened more or less than a value corresponding to a value calculated in the control. An especially economical and safe actuation of the closing cylinder is obtained in this way. <IMAGE>

Title: Geometric body comprising a plurality of cubes with various markings on the cube sides
Inventor: SCHWARZ JOACHIM DIPL ING
IPC: A63F9/08
Filed: 1982-07-17
Abstract: Game for one person. The game comprises a plurality of cubes. Each cube has six outer surfaces (cube sides). A specific number of various markings, by which all the cube sides are characterised, are established. Each cube is thus characterised by the markings on its sides. By matching up the individual markings differently, it is possible to differentiate the cubes. In order to solve the puzzle, first of all one body is chosen. From this body, all the planes of contact between the individual cubes are determined, said planes of contact being designated as interfaces. With the aid of the interfaces, the markings for in each case two adjacent cube sides are established. After establishing the markings for all the interfaces, the markings for the outer sides of the body still have to be established. After that, the markings for all the cube sides, and thus for all the cubes, are known. <IMAGE>
