Title: Fabric fault correction - involves applying layer on faulty garment section to be cut in same pattern
Inventor: GESELLE HELMUT
IPC: D06H1/00
Filed: 1988-05-18
Abstract: To minimise material loss, when laying out fabric for cutting into garment sections, an additional layer is laid for a section with a fabric fault, using the same pattern, so that all sections with faults are relaid. The sections are covered one or more times according to the number of faulty layers monitored in that section. The replacement section is taken from the same fabric as the faulty part, laid over it from the start to cover it, and be cut. Dissimilar faulty sections which overlap as they extend in the laying direction, are treated with a fabric layer which extends from the start to the finish of the laying zone, and if they are spaced from each other, they are covered by a suitable fabric length. ADVANTAGE - The method reduces time in producing faultless cut garment sections where fabric faults are detected.

Title: Overcurrent protection with status message in a floating drive circuit of an insulated-gate transistor
Inventor: HAUW-DOEBLITZ HANTJUN DIPL ING
IPC: H03K17/567
Filed: 1988-07-30

Patent DE-3939057-A1 (DE)
Inventor: HUENING WERNER DR
IPC: B01D53/18
Filed: 1989-11-25
Abstract: The mass-transfer apparatus is based on the principle of the gas washer in which a liquid is injected into the hot gas stream. The apparatus consists essentially of a gas feed pipe (1), which discharges vertically into an injection chamber (2) of greater diameter. Connected to the injection chamber (2) is a mass-transfer duct (12) with a diffuser (13). The injection chamber (2) is closed at its upper end against the gas feed pipe (1) with an annular roof (4). In the annular roof (4) are arranged liquid nozzles (5), directed at an angle downwards. The gas feed pipe (1) does not terminate flush with the annular roof (4) but is extended into the injection chamber (2) in the form of a gas skirt tube (8), so that the liquid nozzles (5) in the annular roof (4) are protected from the hot gas stream.
Patent DE-4000495-A1 (DE)
Inventor: ROTH ROLAND
IPC: B29C55/02
Filed: 1990-01-10
Abstract: For laminating a web (3) with a stretched web (2), the stretching operation for the web (2) is immediately followed by feeding in the unstretched web (3) and laminating it on to a certain extent within the stretching apparatus (4) by utilising the stretching heat - preferably after independent preheating - so that a heat-laminated multilayered web (13) is formed, in which both webs (2 and 3) may consist of the same or the same type of material, which is particularly favourable for reprocessing. The advantages of such a composite web comprising a stretched web and an unstretched web are thus achieved without adhesive being required for forming the bond.

Patent DE-4013176-A1 (DE)
Inventor: SCHABERT HANS-PETER DIPL ING
IPC: F16K31/04
Filed: 1990-04-25
Abstract: In order to protect the spindle (2) displaced in the valve by a spindle nut (6) rotating in a housing (4), two friction surfaces (11, 13) facing each other are pressed against each other when a given threshold force on the spindle (2) is exceeded. One friction surface (13) is attached to rotate with the spindle nut (6) and the other friction surface (11) with the housing (4). The invention calls for at least one (13) of the two friction surfaces to have a free angle ( PHI ) for the rotary attachment. This measure makes it possible to loosen the spindle nut (6) again using a smaller torque than the braking moment which acts in the event of a control failure.
