Patent DE-4300306-A1 (DE)
Inventor: JANSSEN HERBERT
IPC: D03D39/16
Filed: 1993-01-08
Abstract: The invention concerns a method of manufacturing a double-weft double-plush woven fabric with tight ends (3a, 3b) located in the upper part and the lower part of the fabric, between the pile-side and rear-side weft yarns. The two weft yarns in the double-weft binding alternate in pairs, either both in the upper part or both in the lower part, in separate sheds. The dead yarn assemblies (6, 8) interlaced on the upper and lower parts of the fabric are protected from damage caused by the parts (17, 18) of the weft-insertion system which pass through the shed by virtue of the fact that each of the dead yarn assemblies is held or pinched between two superposed or adjacent tight end planes (3a, 3b).

Title: Gas-discharge systems having semiconductor electrodes
Inventor: CHRISTIANSEN JENS PROF DR
IPC: H01J1/38
Filed: 1993-03-09
Abstract: The invention relates to gas-discharge systems having semiconductor electrodes for high currents which are used as switches, lasers or lamps. In all cases, high currents are transported by means of a gas discharge, a plasma taking over the charge transport in a known manner between a cathode and an anode. Two electrodes, to be specific a cathode and an anode, are in this case always arranged at a distance d from each other, the electrodes being separated from each other by an electrically insulating wall of the gas-discharge chamber of non-conducting material such as for example ceramic or glass and the electrodes being connected to the insulating wall by means of a tight connection or fusing and there being present in the gas-discharge chamber a gas filling which can be ionised and which is at such a pressure p that a gas discharge between the electrodes is started (fired, sparked) when a voltage is applied to said electrodes. The gas pressure is characteristic for the individual systems under consideration. The subject-matter of the invention is to improve the service life and the operativeness of the gas-discharge systems by producing the surfaces of the cathode and in general also the anode, which face the current-carrying plasma, from suitably selected semiconductor materials which for their part are connected by means of suitable technical methods to a metal support, are a part of the bushing current of the systems into the exterior space ...

Filed: 1994-11-17
Abstract: A process is disclosed for preparing aldehydes and/or alcohols by hydroformylating olefins with more than 3 carbon atoms with a "naked" rhodium catalyst homogeneously dissolved in the reaction medium at an increased pressure and temperature, then by removing the rhodium catalyst from the liquid reaction mixture. A magnetisable inorganic pigment coated with a polymer binder is used to remove the "naked" rhodium catalyst homogeneously dissolved in the hydroformylation medium. After said pigment absorbs the rhodium contained in the hydroformylation medium, it is eliminated from the liquid hydroformylation medium by exposure to an outer magnetic field.
