Patent DE-4011801-A1 (DE)
Inventor: BAKOWSKY LOTHAR DR
IPC: B05D5/08
Filed: 1990-04-12
Abstract: The invention concerns a process for the thermal coating of surfaces with a fluoropolymer in the form of a powder, sheet, dispersion or suspension which is applied to the surface, at the same time heating the fluoropolymer and the substrate. In order to produce coatings from fluoropolymers wich are prepared from melts, by means of a simple and inexpensive process involving only a few operations, the invention proposes that the substrate be heated and, simultaneously, for the fluoropolymer to be melted using a laser beam, the temperature of the surface being determined over the coating zone and maintained by on-line control within the range between the melting point of the fluoropolymer and 100  DEG C above the melting point. At a film thickness of 100  mu , the fluoropolymer has an absorption coefficient which is lower than 80 % in the laser-beam wavelength range.

Title: Spindle speed control for consistent yarn prod. - varies energy supply to the spindle drives to compensate for spindle speed deviations
Inventor: WARBINEK KURT PROF DR ING
IPC: D01H1/244
Filed: 1990-05-22
Abstract: To maintain a constant spindle rotary speed, at the workstations of a ring spinner or twister, the energy supply to the drives (4) for the spindles (2) is adjusted to compensate for any spindle speed deviation from nominal values. The energy supply to the spindle drives (4) is increased in proportion to the increase in slip at the spindles (2), with controlled monitoring of the energy supply. The increase in energy supply to the spindle drives (4) uses the cops wt. as a guide value, and the yarn thickness or the traveller wt. is used as a guide value to monitor the energy supply. The actual rotary speed of at least one spindle (2, 2') can be taken as the guide value to monitor the energy supply to the drives (4). A programmable guide value transmitter is connected to at least one spindle drive (4) through a controlled energy supply unit (7), to give a program control. The guide value transmitter can form the guide values from the operating parameters of the assembly (1). ADVANTAGE - The operation reduces the effect of slip on the spindles to keep constant running and/or a consistent yarn prod.

Title: Control of injection moulding process - has piston speed regulated by specified relation to piston force
Inventor: HUMMEL ERHARD
IPC: B29C45/76
Filed: 1990-11-08
Abstract: An injection moulding process is controlled by measuring the piston force and the piston speed against time. The internal mould pressure is optimised by maintaining the final piston force between an upper limit and a lower limit so that the difference does not exceed 20% of the force. When the lower value is reached a first time interval, which is preferably between 0.02 and 1 second, is started. At the end of this interval or after the upper piston force limit is reached, the piston speed is reduced by at least half and a second time interval, which is preferably between 0.05 and 3 seconds is started. The injection process parameters of piston displacement, injection time, piston speed and mould temperature are adjusted depending whether the piston force exceeds the upper limit or falls below the lower limit during the second time interval. The optimum is reached preferably in stages of 5, 1, 0.2 and finally 0.1%. ADVANTAGE - Optimum timing of the filling and compression stages is achieved in relation to the point of sudden pressure rise when the mould is full.
