Title: Mineral wool pipe insulation - with edge zones of greater density to avoid use of spacers
Inventor: SEITZ WILFRIED
IPC: F16L59/05
Filed: 1979-05-23
Abstract: Heat insulation for pipes is produced by winding a web of glass or rock wool, impregnated with a thermosetting plastic, on a core under a certain compression and by slitting the blank into two semi-cylindrical cups. To save the statutory spacers required for densities of 70 kg/m3 or less, the ends of the web are made with a greater density of up to 200 kg/m3 by interleaving additional strips of material or by folding over the selv edges and compressing them to a greater density. This leaves the bulk of the heat insulation with a light-weight but saves the spacers for the outer metal shells which cause extra heat losses.

Title: Backflow preventer valve for domestic water softener - has double acting lands operated by pressure of flowing liquid
Inventor: HEISSMEIER WALTER DIPL PHYS
IPC: A47L15/42
Filed: 1980-04-24
Abstract: A water-softener and regenerator unit for use with domestic washing appliances has an automatic double-acting backflow- preventer valve between the mouth of the fresh-water inlet to the ion-exchanger and the mouth of the brine inlet from the regenerator. The valve lands form a single, mutually pre-tensioned unit which closes both valves when the flow of water is shut off, but uses the pressure of the flowing liquid in one or other of the conduits to open the appropriate outlet whilst simultaneously increasing the pressure on the land of the other outlet to hold it firmly closed. This is a simple, compact and relatively inexpensive construction which operates reliably, with little tendency to blockage.

Title: Aircraft surface navigation system - measures ground speed from comparison of image signals in successive image acquisition cycles
Inventor: HORNFELD WILLI DIPL PHYS
IPC: G01C21/00
Filed: 1980-12-13
Abstract: A surface navigation system for aircraft contains an image sensor whose signals, representing the overflown landscape, are fed after processing to a scene correlator also provided with reference image signals from an image memory. The scene correlator determines the aircraft position and the system also determines ground speed. The sensor image signals are fed simultaneously via an image converter and temporary memory to two additional scene correlators. The additional correlators alternately correlate the signals with those from preceding images. The correlator outputs are compared in a processor taking account of flying altitude, image repetition and sensor resolution to enable computation of the ground speed from the image displacement between two image acquisition cycles.
