Abstract: Process for manufacturing shaped parts out of thixotropic metal billets in horizontal pressure diecasting machines such that inclusions of oxide skin surrounding the thixotropic metal billet are avoided in the alloy structure of the shaped part. Before introducing the thixotropic metal alloy into the space inside the mould, the oxide skin surrounding the metal billet is removed completely and collected in a container such that removal of oxide-free, homogeneous thixotropic metal alloy is minimized by taking into account the thermal and mechanical properties of the thixotropic billet, which are asymmetric with respect to the longitudinal axis of the metal billet. The removal of the oxide skin takes place in a horizontal diecasting machine which contains an oxide remover between the casting chamber and the mold. The oxide remover is represented by a ring-shaped body with a horizontal concentric middle axis and a throughput opening.

Abstract: Gas-tight container featuring an outer shell of metal or metal and plastic or metal and cellulose-containing material, a base, a lid and at least one side-wall. The container may be e.g. a can with, as viewed in plan view, a polygonal, round or oval cross-section. The base or part of the base of the gas-tight container exhibits a region which may be made to bulge and which is surrounded by an endless depression and, in the condition in which the can may be used, is in the form of a concave bulge. A container of this kind is such that one can readily recognize if the contents have suffered from spoiling or decomposition and, as a consequence, gas has been formed inside the container. If the pressure inside the container increases, the bulge is pushed outwards and, usefully, may form a convex bulge.

Abstract: Described is a process and an apparatus (10) for the production of thin sections which are cut off a specimen (16), by the use of a cutting blade (20) of a microtome (12), and then transferred to a liquid bath (40). In order to prevent undesired compression of thin sections (98) during the cutting operation, the thin sections (98) are transfer from the cutting blade (20) to the liquid bath (40) by flowing fluid from the cutting blade (20) to the liquid bath, wherein the liquid bath is disposed at a spacing from the cutting blade by a flow passage. The flowing fluid is selectively guided, by a change-over switching device (56), to the liquid bath (40) or to a waste container (52) so that good thin sections (98) are separated from unsatisfactory thin sections (98).

Abstract: Operating Systems (OS's) of the same form are stored in first and second memory areas. The executing Operating System in the first memory area is terminated and the Operating System in the second area is initiated. After system files stored in the first area are released from access lock, they are replaced by substitute files provided in advance by using a file replacing function of the second Operating system. When such a file replacement fails for some reason, the original operating system files are immediately restored by using a backup file. By this invention, the updating of files previously forbidden by the Operating System in the first memory area to be accessed as well as the restoration of files at the time of update failure can be achieved by software.

Abstract: A process for joining components made of metal, in particular aluminum and aluminum alloys, is such that a thermally-curable (hardenable) adhesive is deposited between the close-fitting surfaces of the components that are to be joined, and one of the outer surfaces neighboring the said close-fitting surface of one of the components is radiated with infra-red radiation in order to cure the adhesive. At least the outer surface to be radiated is provided with a pattern that roughens that surface. By reducing the reflectivity of the roughened surface the capacity to absorb infra-red radiation is increased. A preferred application for the process is in the adhesive bonding of shaped parts, especially body sheet in automobile manufacture.
