Patent DE-3730830-A1 (DE)
Title: Arrangement for heat transfer by means of a Peltier device
Inventor: BUCHMANN MARTIN DIPL ING
IPC: H05K7/20
Filed: 1987-09-14
Abstract: The invention is based on an arrangement for heat transfer by means of a Peltier device between components in an equipment casing and the outside air outside the equipment casing. The Peltier device is to have its working side in area connection with a component casing holding at least one module consisting of components. The connection may also be made directly with the module. The Peltier device's other heat exchanger, acting externally, penetrates the equipment casing at least by means of heat-transfer bridges. In contrast to conventional cabinet cooling, the electronic module or a component that can only operate in a certain temperature range is cooled in a specified manner, without the temperature of other modules being affected. Warming can also be done on the same principle. <IMAGE>

Title: Acceleration-sensitive electronic component
Inventor: GRANDKE THOMAS DR
IPC: G01P15/135
Filed: 1987-12-14
Abstract: An inertial body (8) is connected in a self-supporting manner via carrying beams (6) to a support frame (4) and is provided on one planar side surface (9) with an electrode (10). Opposite this electrode (10), an opposing electrode (22) is arranged on a base (20). In this way, acceleration-sensitive switching elements and also capacitive acceleration pickups may be realised. According to the invention, a plurality of mutually opposite carrying beams (6) are provided, which are arranged in such a way, that acceleration forces acting perpendicular to the opposing electrode (2) cause a linear movement of the inertial body (8). It is possible in this way to increase the surfaces of the electrode (10) and the opposing electrode (22) and therefore also the surface of the switching contact and the capacitance of the component. In a particularly preferred embodiment, the inertial body (8), the carrying beams (6) and the support frame (4) form a monolithic silicon body (2). Acceleration-sensitive switches, capacitive acceleration pickups. <IMAGE>

Title: Movable dental prostheses (epiprosthesis) of plastic with fibre reinforcement
Inventor: KEGEL KURT PROF DR ING
IPC: A61C13/00
Filed: 1987-12-16
Abstract: The invention relates to plastic dental prostheses which, owing to their frequently inadequate flexural and torsional strengths, break due to the high load during mastication. According to the invention, these prostheses contain inlays of short (whiskers), long or continuous graphite fibres embedded during production or already in the precursor, which considerably increases their strength, as experiments have shown. Graphite in general and in this fibre form is highly tolerated by the body. The plastic dental prostheses containing graphite fibres of this type can, if necessary, be repaired, which is not the case, for example, when glass fibres are used. In addition to graphite fibres, it is also possible to use other graphite products or high-tenacity polyethylene fibres which are heat-stable up to about 150@C; their colour is the same as that of the plastic. The grey to black colour of the graphite gives the plastic prosthesis a purple to violet colour; if this is a hindrance in individual cases, the graphite fibres can be coloured.

Title: Grass paving stone
Inventor: WERTEBACH GUIDO
IPC: E01C9/00
Filed: 1988-02-16
Abstract: A description is given of a grass paving stone 1 which can be laid so that not only the lateral distance to the neighbouring grass paving stone 1 and hence the width of the joint 3 can be precisely defined, but, in addition, also a certain positive locking between neighbouring grass paving stones can be achieved. Projections 8 and 9 are thus provided in certain areas as joint spacers on the lateral faces 4 and 6 of the grass paving stone 1 which are directed substantially normal to the laying plane. The free end faces 16 and 17 of the joint spacers or projections 8 and 9 have a contour which differs from the main direction of the lateral faces 4 and 6 carrying them. The end faces 16 and 17 of the projections or joint spacers 8 and 9 of grass paving stones 1 laid adjacent to one another can be brought into engagement with one another in interlocking fashion and thereby produce the desired positive locking. <IMAGE>

Title: Device for the hygienic processing of liquids
Inventor: BOEHNENSIEKER FRANZ
IPC: C02F1/28
Filed: 1988-08-18
Abstract: A device for the hygienic processing of especially drinking water, comprises an UV radiation source (13, 14) in a tubular body (10) of a UV-permeable material which extends through one or more regions (7, 8, 9) arranged one behind the other in the flow direction of the water in the device through which the water to be processed flows and which are separated from one another by activated carbon filters (5, 6). The water to be processed is therefore exposed each time to germicidal UV radiation before entry in the activated carbon filters (5, 6), and this eliminates the danger of excessive growth of organisms in the region of the activated carbon filters (5, 6). Before leaving the device the filtered water is exposed to another intensive germicidal irradiation in the tubular body (10). <IMAGE>

Title: Apparatus for the cold rolling of metal strip and foil and a method for its operation
Inventor: LEHMANN ROLF
IPC: B21B27/02
Filed: 1988-08-27
Abstract: In the cold rolling of a metal strip down to foil thickness, flatness of the rolled metal strip is achieved, while avoiding distortion and bending, by the fact that a roll (7) is designed as a bend adjustment roll controllable individually across the width of the web and an opposing mating roll (8) as a roll with a controllable effective camber. The longitudinal tension profile of the rolled metal strip (1) across the width of the web is subjected to a harmonic analysis with a fundamental wavelength corresponding to the width (L) of the web, the fundamental (a2) serving to control the effective camber of the mating roll (8) while higher-order waves (a3, a4) are used for the individual control of the supporting elements (13) of the bend adjustment roll (7). The control range and the possible adjustment range of the rolling force without the occurrence of flatness deviations are thereby increased, as is the control rate. <IMAGE>

Title: De-watering mud, sludge, etc. - by passing down between two concentric conical filter surfaces, compressing into pellets and drying
Inventor: KASTEN HEINZ
IPC: C02F11/125
Filed: 1989-05-26
Abstract: Sepn takes place on a conical sieve or filter surface.  The material to be de-watered passes downwards between two concentric conical filters, whose porosity as well as surface area decreases in thee downwards direction.  Filteration may be assisted by the application of pressure from a compressed air supply to the material being treated.  he rate of movement of the material between theconical filter surfaces is controlled by the speed of a compressing screw conveyor attached to the outlet from the filter space. This conveyor is provided with a screw with a reducing pitch so as to further de-water the material being treated, and may compress the material into a pellet form. The pellets produced are allowed to fall through a rising hot air stream into which quicklime is injected. The heat evolved when the lime is  slaked by the residual moisture in the )pellets increases the drying effect and the pellets are coated with lime. USE/ADVANTAGE - This invention is used in the drying of mud, sludge and similar materials. The capital cost of the proposed device is far less than that of machiness currently used for this purpose (centrifuges, presses etc.), it is easy to operate, it energy efficient and can be installed indoors or outdoors.
