Patent DE-19726667-A1 (DE)
Inventor: TELES JOAQUIM HENRIQUE DR
IPC: C07C43/16
Filed: 1997-06-23
Abstract: The invention relates to a method for producing enol ethers of formula (I), in which R<1> is an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radical, which radicals can carry other substitutes that do not react with acetylenes or allenes; the R radicals are, independently of each other, hydrogen, or aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radicals, which can interconnect forming a ring; and m stands for 0 or 1. In this method, acetals or ketals of formula (II) are reacted with acetylenes or allenes of formula (III) or (IV), in which the R and R<1> radicals have the aforementioned meanings. The reaction takes place in the gas phase, at high temperature, in the presence of a heterogeneous catalyst containing zinc or cadmium together with silicon and oxygen.

Title: Post-processing method for computer tomograph of medical X=ray diagnosis
Inventor: WOHLRAB JUERGEN DIPL ING DIPL
IPC: G06T5/20
Filed: 1997-08-20
Abstract: The method involves using an universal computer (8) for a post-processing of a reconstructed sectional image of a layer of an examined object (O). The sectional image represents the entire measuring field (10) of the computer tomograph (1) or a section of the measuring field.

Title: Process for deriving crystallization process control and on-line monitoring parameters
Inventor: ULRICH JOACHIM
IPC: B01D9/00
Filed: 1997-09-17
Abstract: Crystallization process control and on-line monitoring parameters are derived from propagation velocity measurements of ultrasonic waves in the crystallizing solution. Derivation of parameters for process control and on-line monitoring of crystallization of a dissolved substance is carried out by repeatedly measuring the propagation velocity of ultrasonic waves in the supersaturated solution in dependence on the change of solution state values, extracting process control parameters from the velocity changes and, during the crystallization process, deriving control values for the process. An Independent claim is also included for equipment for carrying out the above process, comprising a measuring probe which is located in the crystallizer (1) or a connected component (4) and which has a temperature sensor and an ultrasonic transmitter and receiver combination for determining the ultrasonic wave propagation velocity, the probe being connected to a measurement display unit and/or a process control value derivation unit.
Patent DE-19742181-A1 (DE)
Title: Semiconductor component manufacturing method for IGBT, DMOSFET
Inventor: TOMATSU YUTAKA
IPC: H01L21/3065
Filed: 1997-09-24
Abstract: The method involves using a component having a source region (8) at the top on side face of the groove (9). A channel region (7) is positioned under the source, and a gate electrode (11) extends through a gate insulating layer (10) to be located at an angle between the groove side face and the surface of a substrate (1, 4). A mask with an aperture section at a preset region of the substrate surface is formed. Thus the groove is formed on the substrate surface and is exposed at the groove outer edge. Finally an inner surface of the groove and the substrate exposed surface is oxidised to form an oxide film which is then removed.

Title: Selective gas phase oxidation of n-butane to maleic anhydride with very active catalyst easily produced on large scale
Inventor: CONTRACTOR RASHMIKANT MAGANLAL
IPC: C07B61/00
Filed: 1997-09-29
Abstract: Selective gas phase oxidation of n-butane to maleic anhydride is carried out in a transfer bed reactor with (1) a reaction zone, in which n-butane is converted to maleic anhydride with a vanadium/phosphorus oxide catalyst (V/P/O catalyst) in the oxidised form and (2) a catalyst regeneration zone, in which the reduced V/P/O catalyst is regenerated by contact with oxygen (O2). The novel features are that (i) the catalyst precursor is introduced into the regeneration zone, which is kept at 380-400 deg C; (ii) the precursor is fluidised with air or gas containing O2 for long enough and at a suitable pressure to remove entrained organic compound and (partly) dehydrate the precursor; (iii) the calcined precursor is transferred to the reaction zone after an average residence time giving an average vanadium oxidation state (Vox)  <=  4.55; and (iv) the calcined precursor is kept in the fluidised state in the reaction zone with a non-oxidising gas until the start of catalyst circulation. Also claimed is a method for calcining a V/P/O catalyst.

The distances for which adjustment takes place when pulling the plate onto the cylinder, and also when pressing the plate against the latter, is greater than the difference between (a) and (d).
Patent DE-19748923-A1 (DE)
Title: Method and apparatus for starting a continuous casting process
Inventor: LEHMANN HOLGER DIPL ING
IPC: B22D11/08
Filed: 1997-10-30
Abstract: The cold billet and the starting section have a format which corresponds to the roll gap at the exit from the billet guide section.  The free space (29) is filled with a filler material which after the start of the casting process is jettisoned to free this space for the starting section of the billet. An extension piece with a sealing collar (47) attached to the head of the cold billet (41) is introduced into the mold (21).  The melt is poured into the mold so that it forms a close joint with the extension piece.  After a sufficiently long starting section has formed, the cold billet together with this starting section is extracted from the mold.  The extraction rate is chosen so that the outer wall of the starting section being produced can gradually adapt itself to the mold inner wall while a shell is formed around the molten billet core.  The cold billet and the starting section have a format which corresponds to the roll gap at the exit from the billet guide section.  The free space (29) is filled with a filler material which after the start of the casting process is jettisoned to free this space for the starting section of the billet.
