Title: Winch for open-width wet treatment of textiles - using low liquor ratio applied in fan-shaped spray
Inventor: KREITZ HANS
IPC: D06B3/28
Filed: 1979-02-15
Abstract: Equipment for the continuous wet-treatment of textile fabric in open width with a low liquor ratio has a liquor spray producing a fan-shaped stream of liquor which impinges on the moving fabric at an acute, but varying angle, assisting the transport and layering of the material. The fabric passes through a U-shaped chamber in contact with the liquor, whence it is drawn off, mangled, and may be subjected to repeated treatments in additional, similar chambers. The process gives high-quality results on low liquor ratios of 1:3 and relatively low throughput speeds of 80-120 m/min. The treatment is uniform across the width of the fabric and free from danger of setting-in creases or over-working the fabric. Rinsing efficiency is considerably increased, giving savings in time, and in water and energy consumption.

Title: Microprocessor controlled home telephone system - stores dialled number and repeats dialling on command, and erases number only when exchange is dialled again
Inventor: FAHRENSCHON FRANZ DIPL ING
IPC: H04M3/424
Filed: 1979-09-13
Abstract: A telephone system for installation in a home allows one main and four extensions to make internal calls or use the exchange line, and is controlled by a microprocessor. An outside call is made by lifting a receiver and dialling the exchange code and number to be called. This is heard by other extensions engaged on an internal call but does not interrupt their call. The microprocessor recognises the exchange code and stores the number. It switches the calling extension to the exchange busbar and connects the busbar to the exchange line. It reads out the number and sends dialling pulses on the line via a transistor pair driven by an optocoupler, which protects the microprocessor from line interference. Dialling can be repeated by dialling a one digit code. The stored number is not erased until exchange code is dialled again.
