Title: Finishing process for laundered fabrics containing polyester blends - which removes thermo-fixed creases by spraying with hot water
Inventor: GRUNEWALD HEINZ LUDWIG
IPC: D06F73/02
Filed: 1978-09-26
Abstract: In a finished procedure for laundered garments made from blended fabrics of polyester/cotton, before the garments are dried, they are sprayed with hot water at 70-90 degrees C for about 0.5 min. before or during a steaming treatment at 120-150 degrees C lasting 1-3 min. The garments, hanging vertically without any contact between them in a suitable chamber are sprayed from overhead conduits running along the upper part of the chamber so that both sides receive equal treatment, and are subsequently dried off by hot air currents passing through the same chamber. The process gives a smooth, flat finish to the fabric without requiring further expensive processing such as pressing, and in partic. it removes even sharp, thermofixed creases which resist simple steaming treatments. This enables industrial washing machines to be used to their full capacity, with normal water : fabric ratios, since the resulting creases can be effectively removed.

Title: Ignition and fuel-injection control system for engine - has microprocessor needing few bits since certain operations are performed by input-output unit
Inventor: JEENICKE EDMUND
IPC: F02D41/24
Filed: 1979-01-03
Abstract: The ignition and fuel-injection control system has the input/output unit of its microprocessor designed so that the least possible number of bits, pref. 8 is needed. This is accomplished by displacing some of the operations normally performed by the processor into the input/output unit. These operations are the detection of a variable's limit (esp. engine speed) and generating freely-programmable frequencies. A counter receives pulses via the data-bus and counts them under the control of variable dependent signals. The counter therefore acts as a limit detector. The programmable frequency generator is realised by changing over to control by overflow signals.
