Patent DE-3128977-A1 (DE)
Title: Process and device for producing composite articles
Inventor: BRATSCH KURT
IPC: B29C63/22
Filed: 1981-07-22
Abstract: For producing a composite article consisting of an air-impermeable backing, for example a dashboard, and a sheet which is also air-impermeable, an adhesive layer is applied to the backing and/or the sheet and the preformed sheet is placed on the backing, whereupon the two parts lying at first loosely one on top of the other are subjected to a subatmospheric pressure in an autoclave, so that the air between the two parts is removed. Then the subatmospheric pressure on the underside of the composite article is maintained while the top side of the composite article, that is to say the side with the sheet, is subjected to atmospheric pressure or a slightly superatmospheric pressure. During this, the sheet is heated to such an extent that thermal activation of the adhesive layer occurs. After the activation of the adhesive means, the heating operation being carried out by means of heating fans, the composite article is cooled by means of cooling fans and removed from the production process. This process is carried out using a turntable consisting of a plurality of individual tables which have a tensioning frame on guides, which tensioning frame can sealingly press the overhanging edge of the sheet lying on the backing against the table, after the air between the superposed parts has been removed in the autoclave. Heating fans (20) are used for heating the sheet and thus the adhesive layer to thermally activate the latter. Then the composite article is cooled by means of cooling fans.

Patent DE-3142909-A1 (DE)
Inventor: BALLMER HORST DIPL-ING
IPC: G02F1/17
Filed: 1981-10-29
Abstract: A continuous change in color is provided in order to control the absorptance of an electrochromic layer. The quantities of charge to be fed and removed by two sources of constant current are measured with a forward/backward counter. For decoloring processes, smaller amounts of charge are removed from the layer than are supplied to it for corresponding coloring processes. The quantities of charge removal for decoloring processes are, however, slightly greater than the quantities of charge which are theoretically necessary to obtain intermediate values with exactly the same absorptance, thereby assuring against destruction of the layer, even in case of numerous changes between different colorings. Preferred fields of use are lenses, particularly eyeglass lenses, filters and dimmable mirrors, using an applied electrochromic layer whose absorptance is varied.

Filed: 1981-10-29
Abstract: The hand grinder is an innovation which has been thought through right down to the very last detail. The technology of the hand grinder enables anyone to sharpen any type of knife without any prior knowledge whatsoever. The user of the grinder sharpens the knife with a simple movement - as in slicing bread. The technology of the grinder produces a lasting grinding angle and knife guidance. The grindstones in the top part are next to one another in an X-shape. They are matched by guidance and spring mounting in such a way that they diverge up to the V-shape during drawing or revolving pressure, in the course of which they always retain the uniform grinding angle. So that the knife maintains the absolute vertical, a knife guide is provided for this purpose.
