Patent DE-3115730-A1 (DE)
Title: Method and device for cooling and cleaning metal castings
Inventor: KOEBEL ALFONS ING GRAD
IPC: B22D29/00
Filed: 1981-04-18
Abstract: In a method for cooling and cleaning metal castings produced in sand moulds, the casting is, after being shaken out from the sand mould, first of all subjected to preliminary blasting with continuous controlled changing of its position, subjected during and/or after this procedure to a cooling medium and finally subjected to finish-blasting. Reheating of the casting by adhering residual sand is thereby avoided. The apparatus for carrying out the method comprises a preliminary blasting device (3), at least one cooling device (12 - 14) and a finish-blasting device (16), through which the casting passes in a certain relative position but with a continuous change in its own position. <IMAGE>
Patent DE-3116369-A1 (DE)
Title: Bicycle valve
Inventor: RISSMANN HORST-GUENTER
IPC: F16K15/20
Filed: 1981-04-23
Abstract: The invention relates to a bicycle valve and is intended, in comparison to the previously known designs, to increase the reliability of the mechanical connection to the rim and the ability to retain pressure and, in addition, to increase the ease of assembly. For this purpose, the outer contour of the bicycle valve is basically chosen such that the valve can be pushed through the rim hole as a completely assembled unit. As a result, automation of the initial assembly of bicycles, which hitherto was not possible, is made possible. By using two valve members in a valve insert which can be adjusted in a sealing manner in the valve body, three seals are produced, thus making it more difficult for air to escape. Furthermore, a bayonet-like connection is provided between valve body and rim, which connection benefits the durability of the inner tube. The satisfactory fixing of the valve relative to the rim prevents the additional stresses on the inner tube which previously had to be accepted, which when attaching the valve resulted in permanent deformation of the inner tube and also when pumping up the tyre could cause damage in the region of the connection of the valve body to the inner tube.

Title: Flexible skin or material web for or as structure surface
Inventor: RAUPACH PETER
IPC: F24S10/70
Filed: 1981-06-27
Abstract: The invention relates to a flexible skin or material web for or as roofing and walls or similar structure surface, in particular in the case of swimming-pool halls or similar sports areas, having a fabric-like supporting structure. Said skin or web is to be configured such that it permits, on the one hand, better conditioning of the air in the hall or structure and, on the other, utilisation of solar radiation. This is achieved in that the supporting structure is provided with flexible hollow profiles or hollow threads which provide a system of flow ducts for a fluid as energy carrier and are designed such that they can be connected up to a heat exchanger or the like. The hollow profiles or hollow threads are preferably to be processed within the skin as warp threads or weft threads and are to be produced from UV-resistant plastic which, in addition, is coloured black by means of soot or pigments. <IMAGE>

Title: Method and device for increasing the light intensity (level) in diaphragm gaps of arbitrary shape
Inventor: REINERT GUIDO GEORG
IPC: G02B3/06
Filed: 1981-07-13
Abstract: The invention relates to a method and device for filling in light in gaps, characterised in that the cross-section of an illuminating beam path, which is rendered telecentric in a known way, is brought with the aid of a glass element whose total optical (dioptric, focal, refracting) power is equal to zero to a small cross-section corresponding to the gap width and shape. This method can be applied both in the case of rectilinear and in the case of curved or annular gaps, and permits a substantially better utilisation of light by comparison with the known illuminating arrangements for illuminating gaps.

Patent DE-3136898-A1 (DE)
Title: Test device
Inventor: BARTH HANS
IPC: G01R1/073
Filed: 1981-09-17
Abstract: A test device exhibits a contact-making device by means of which circuit boards to be checked can be pressed against contact needles for making contact. This is done by means of a pressure plate acting on the circuit board, which plate is connected to a lifting device. This lifting device exhibits at least three, preferably four jointly driven threaded spindles, preferably rolling-ball or ball screw spindles as lifting elements. These handle both the height adjustment and the guiding at the same time. With a predetermined contact-making lift, the starting position of the contact-making movement can be changed by the drive motor being separated from the joint driving element of the threaded spindles by means of a clutch and the starting position then being set. This allows circuit boards of different thickness to be tested without cumbersome resetting work.

Patent DE-3141083-A1 (DE)
Title: Aid for preparation of a ceramic tooth
Inventor: WEIDNER JOACHIM
IPC: A61C19/00
Filed: 1981-10-16
Abstract: A working plate with a plurality of receiving wells is used as an aid for preparation of a ceramic tooth. The individual receiving wells are intended for ceramic materials of different colours and are allocated to geometrically different dental zones which are to be imparted correspondingly different colour shades. An enlarged tooth or dental zone contour bounds the total well field or the corresponding wells. The essential advantage of this allocation of wells to specific dental zones resides in the fact that the prepared ceramic materials of different colours can be kept available without confusion even over a fairly long period. This is advantageous for subsequent application of ceramic material in specific areas after a burning operation or the like.
Patent DE-3141721-A1 (DE)
Title: Device for selectively changing the penetration of sun or light and heat rays through windows and/or for changing the heat insulation of windows
Inventor: FISCHER HEINZ
IPC: E06B3/67
Filed: 1981-10-21
Abstract: The device utilises the cavity between two or more panes of glass or sheets of plastic. Said cavity may be filled with air, gas or liquid. At selectable times and in selectable densities, particles or bodies are introduced into the cavity which have a heat-insulating and/or reflective and/or decorative effect. The introduction and removal takes place by means of a flow of air, gas or liquid through openings in the frame in the case of fixedly mounted windows or, for example, through the pivot point of window wings. The said cavity can be formed by means of a third pane in the case of windows with laminated or insulating glass or by two suitably arranged panes alone. The particles or bodies introduced into the cavity can assume the function, for example during the night, of increased heat insulation and, during the day, that of vision screening or shielding from undesired irradiation. The introduction can take place fully automatically. Due to the arrangement between two or more panes or in the interior of the frame or of the space, the device is fully weather-protected and thus not susceptible to malfunction.

Patent DE-3215713-A1 (DE)
Title: Device for scanning an image on a transparency by means of a television camera
IPC: H04N1/10
Filed: 1982-04-28
Abstract: This device uses a projector. Scanning a transparency from a ground-glass screen onto which the transparency is projected via a semitransparent mirror has disadvantages because of a significant deterioration in image quality. This also applies to the scanning of the image from a projection screen onto which the transparency is projected. By comparison, the invention proposes to design the lamp of the projector to be used for a light power which is reduced by at least 50 % in comparison with the light power of the lamp of a normal projector, and to project the transparency directly onto the pick-up tube of the television camera. This leads to a significant improvement in the image quality whilst at the same time reducing the technical outlay.
