Granted: 1986-07-17
Abstract: In the gas carburization of steel, a steel part is exposed in a carbon-enriched atmosphere of a furnace to a diffusion process to form a boundary layer with an increased carbon content, determined as a function of the distance from the surface. The values of importance for the diffusion process are determined intermittently and used as control parameters to affect the diffusion process. The flow of carbon diffusing directly through the surface of the steel part serves as the measured value. The supply of the carburizing gas is controlled as a function of this value.

Filed: 1984-09-29
Granted: 1987-01-15
Abstract: A method and an apparatus are described for processing and applying a protective foil to a flat sheet made, more particularly of a thermoplastic synthetic material. The protective foil is used to protect the relatively soft surface of the sheet but, during further processing, difficulties arise in that parts of the surface must be freed of protective foil. In order to protect at least certain areas of the sheet as long as possible from external effects or damage, there is provided a protective foil which, before it is applied to the sheet or to a strip from which the sheet is subsequently produced, is formed with perforations. During further processing of the sheet, the parts of the foil corresponding to the areas of the sheet that are to be freed, are removed and the remainder is protected by the remaining parts of the protective foil.

Abstract: A process for coating composite profiles with powder lacquers, comprising two profile parts of metal and at least one insulator of plastic, interconnecting these profile parts while at the same time forming a heat bridge, comprises the electrostatic application of a lacquer powder to the outer sides of the composite profile and the subsequent sintering together of this powder under the effect of heat to form a lacquer coating. The outer sides of the plastic insulators to be coated have applied to them beforehand a thin, electrically conductive coating which, during sintering of the lacquer powder, improves the adherence of the latter on the insulator. An insulator produced by this process has on its one outer side a thin, electrically conductive coating which, during sintering of the lacquer powder, improves the adherence of the latter on the insulator. <IMAGE>
