Patent DE-3433088-A1 (DE)
Title: Process for selective energy generation from solid fuels, with separating off volatile constituents, sulphur and ashes, and utilisation of the arising inorganic constituents etc.
Inventor: WISSING WILHELM
IPC: C01B17/027
Filed: 1984-09-08
Abstract: Solid fuels are carbonised in the wet state at low temperature and the carbonisation gas is processed as crude gas together with hydrogen sulphide produced from free sulphur and paraffin, and is utilised with recovery of the free sulphur. The remaining carbon is suitable for combustion and gasification, because it is sulphur-free.   In gasification, carbon monoxide CO according to the Boudouard equilibrium or water gas CO+H2 are produced selectively. Carbon monoxide CO and water gas CO+H2 are suitable for combustion in gas turbines, if the combustion takes place under pressure and the gas does not contain any extraneous substances. As a result, boiler houses, flue gas desulphurisation, cooling towers and waste heaps become unnecessary. The waste gas is denitrified. Carbon monoxide CO, carbon C and steam H2O are utilised alternately for producing homologous alkanes and alkenes. The inorganic ballast materials are utilised.

Title: Method of treating surfaces infested by bacteria and/or fungi, etc.
Inventor: HOELTER HEINZ DIPL ING
IPC: A61L2/24
Filed: 1985-02-11
Abstract: It is known to combat pests, e.g. bacteria, viruses or fungi, which have settled on surfaces, by spraying on chemical agents. However, this type of pest control results in the development of pest strains which as the years go by become resistant against said chemical agents. In order nevertheless to eliminate these pests it is proposed, according to the invention, that very small surface areas be exposed successively to several thousand mm vacuum and treated by rinsing with air and/or water in the vacuum region on the suction surface, the carrier and surface-rinsing medium being air or a mixture of water or air and water, which is sucked off by a high-power generator, preferably a vacuum pump, and the surface itself be exposed to a vapour jet, an air jet or a combined water/air or water/air/vapour jet. The treated surface is sucked off immediately via the high-power vacuum pump, the surface itself being treated, depending on the severity of the pest infestation, with an electron beam and/or, depending on the type of pest, by ultra radiation, and the suction device, e.g. a water ring pump, which is also equipped with ultrasound and UV radiation units, separates off the emergent air through bactericidal chemisorption filters into the space or via a hose into the open air.

Title: Method of steam sterilisation or disinfection of porous goods
Inventor: AULENBACH KURT DIPL ING
IPC: A61L2/07
Filed: 1985-02-15
Abstract: In a method of steam sterilisation or disinfection of porous goods inside a treatment chamber in which charges of different sizes are introduced, the treatment chamber is charged at least once with a vacuum during the venting phase and then with steam. In the treatment phase, the treatment chamber is charged with steam until the sterilising or disinfecting point is reached. During charging with steam, the speed - based on time - of pressure increase in the treatment chamber is measured and, in the case of a measured high speed, the time of the venting phase is chosen to be long, and when a low speed phase is measured it is chosen to be short in order automatically to effect optimally short batch times as a function of the particular charge in the treatment chamber.

Title: Plastics housing having a conductive film
Inventor: ITO TOSIKAZU
IPC: B29D99/00
Filed: 1985-03-12
Abstract: With the process according to the invention, a plastics housing is produced which has a conductive film, effectively screens electromagnetic waves and prevents electrification. The process comprises the stages of:   - releasably applying a material containing a coarse conductive powder to a mould surface of a mould group to form a plastics housing, - drying the applied conductive material to form a solidified film,   - injection moulding a liquefied thermoplastic material under high pressure into the mould group and compressing the solidified film under high temperature and high pressure of the thermoplastic material, causing the solidified film to be anchored in the contact surface, opposite the solidified film, of the cast housing. The conductive film of the plastics housing thus produced has a highly aggregated layer in which particles of conductive powder are densely concentrated in point-to-point and/or surface-to-surface contact, so that the contact surface of the particles is substantially increased.   r

Title: Method and device for process control of welding processes
IPC: B23K9/09
Filed: 1985-03-23
Abstract: The invention relates to a method and a device for process control of welding processes, in the case of which method the welding process is controlled by monitoring the process-specific welding parameters from arcs which react to disturbance variables, by means of test equipment, and coupling to the welding burner of the welding process. The welding process is intended to be protected against undesirable extinguishing of the arc and against undesirable reignition as a result of a short-circuit link. As the solution, it is proposed that the control of a current source be tested continuously in order to determine whether processes are taking place outside the bandwidth of reference variables, to be precise especially for the basic voltage, pulse voltage, basic current, pulse current, duration of the pulse-current phase and/or the basic-current phase. If at least one of the reference variables is exceeded in either direction, the welding process is influenced, especially by switching off the control system of the current source. <IMAGE>

Title: Cleaning cassette for cassette-operated magnetic tape devices
IPC: G11B23/04
Filed: 1985-06-29
Abstract: Depending on the type of cleaning tape accommodated in these cleaning cassettes, they exhibited the disadvantage that residues from the cleaning tape remained on the magnetic head during the cleaning process or that, when cleaning tapes of plastic were used, the very sensitive magnetic heads of the magnetic tape device were irreversibly damaged. Video magnetic tape devices exhibit rotating sound heads which have high-resolution surface structures and could therefore not be cleaned by means of the known cleaning tapes because of the risk of destruction of the video magnetic head, or in addition to the contamination, cleaning tape residues remain on it. To eliminate this defect, it is proposed to provide a cleaning cassette (10) which exhibits a cleaning tape (14) which is made of a silk fabric (15). <IMAGE>
