Patent DE-3906268-A1 (DE)
Inventor: STIGLER ANTON
IPC: B28B3/10
Filed: 1989-02-28
Abstract: It has so far been possible to produce certain ceramic profile sections with a relatively long length compared to their diameter only by wet-extrusion methods. This applies above all to the manufacture of catalyzers. To provide a simpler, improved process, it is proposed that the production of such profile sections be carried out in stages. Relatively thin layers are compressed zone by zone, in sequence, so that a press bond is formed with the previously compressed zone. The process and device are particularly suitable for the manufacture of catalyzers consisting of ceramic materials.

Filed: 1989-04-12
Abstract: A method for continuously checking a screen display for signal reliability is specified. The image data, which are processed in parallel in two mutually independent channels and are stored in frame buffers (BWS1, BWS2) of two screen drive computers (VC1, VC2), are read back by the screen drive computers following a signal from a higher-level computer system (MEM) with signal reliability, and are in this case logically combined with a redundancy polynomial. The test redundancies thus formed are transmitted to the higher-level computer system for comparison. The higher-level computer system triggers a reliability response if the test redundancies transmitted do not correspond or do not arrive at the correct time. <IMAGE>

Title: Cooling and lubrication of mandrel by single medium - in piercing and elongating hollow ingots
Inventor: STAAT KARLHANS DIPL ING
IPC: B21B25/04
Filed: 1990-02-10
Abstract: In cooling and lubricating of mandrel rods during the piercing or elongation of hollow ingots, the coolant or lubricant is directed lengthwise through the mandrel rod to the rod head.  For the cooling and lubrication, a single medium is fed in, used and removed. It is directed through the mandrel rod head (2) but periodically also sprayed out through outlets (10) in the rod (1) and/or the rod head (2). Variants include the addition of a deoxidation agent to the medium. USE/ADVANTAGE - In piercing or elongation hollow ingots, the cross-sections of the inlet and outlet lubrication and cooling medium passages, in particular when a mandrel rod is of small outer dia., are usually too small for adequate lubrication and cooling.  System overcomes this drawback by its ability to use a single medium for both cooling and lubrication.
