Title: Producing lining on inner surface of extrusion channel etc. - from isotropic powder metallurgical material isostatically compressed to form compact coating
IPC: B29C48/68
Filed: 1987-10-10
Granted: 1988-11-24
Abstract: Lining is produced on the inner surface of the extrusion channel and, where required, on the outer surfaces of a screw in an extrusion screw press for thermoplastics from a homogeneous isotropic powder metallurgical material, which is isostatically compressed to form a compact coating of the theoretical density of the material. The coating is joined to the channel wall or the screw surfaces by diffusion welding, using the hot isostatic pressing technique. The coating can be applied to unhardened, machined surfaces and compaction and welding can be carried out simultaneously. ADVANTAGE - Homogeneous coating of low wear and/or corrosion-resistant material can be applied, without inclusions.

The equipment has a screening stopper which can be inserted into the opening and which closes off the screening wall in a gas-tight manner, as well as a plurality of rotatable hollow cylinders arranged in the screening stopper, which contain the tool as well as service devices for auxiliary work and viewing equipment. The tool consists of a tool head, a linkage, which can be folded together, having a mechanism for guiding the tool, as well as of drive elements for the mechanism. These are connected to a copying device with which all of the manipulations to be carried out in the reactor pressure container can be tracked. The screening stopper, with its devices, is inserted into the opening and removed by means of a charging and withdrawal container. <IMAGE>

Patent DE-4127249-C1 (DE)
IPC: E21D21/00
Filed: 1991-08-17
Granted: 1993-02-04
Abstract: In order to improve the discharge conditions of a cleaning fluid containing rock particles loosened during the drilling stage, the proposal is for an injection drilling anchor, of which the anchor rods (2), coupling sections (3), compression valves (15), an intermediate component containing a nonreturn valve (9) and a drilling head (1) are designed so that these components can always be screwed together to provide a complete uniform structure on the outside from the drilling head (1) when assembled. A feature of said structure is an outside thread extending uniformly over the entire length and hence a uniform diameter, so that once drilling is completed, a spacer can be pushed from the drill-hole aperture over the anchor rods (2) to any point along the entire length inside the drill-hole. The anchor rods (2) are uniformly internally threaded over their entire length so that even sectioning does not adversely affect their suitability for use in connection with the injection drilling anchor (1). The coupling component, the compression valve (15), the intermediate component (9) and the drilling head (1) have tubular cylinders (20, 21; 10; 6) for this purpose, the internal and external threads of which correspond structurally to the anchor rods (2) and form a stop for screwing-in positions.

Patent DE-4236264-C1 (DE)
IPC: C23C14/56
Filed: 1992-10-27
Granted: 1993-09-02
Abstract: Measurements of certain non-optical properties, in particular mechanical properties, during the industrial production of layers, enabling said layers to be reproducibly formed, in particular when the hardness, wear resistance and barrier effect required are high, cannot be carried out in situ. The values of the optical layer properties are to be used as regulating signals. Immediately after the substrate runs through the vaporisation zone, the reflection and/or transmission and the absorption capacity in the wavelength range  DELTA  lambda  = 150 nm to 800 nm are measured, and the refraction index and the optical absorption coefficient are derived therefrom. The thus determined values are compared with an experimentally determined set value. A regulating signal derived therefrom regulates the plasma at a constant reactive gas partial pressure and maintains constant the optical properties of the layer. This process is useful for vaporising wear-resistant, hard layers or barrier layers, for example metal oxide layers, on glass, plastics and other materials; for example in the building industry fo manufacturing glass for façades, and in the packaging industry.
