Title: Safety mechanism for water softening units in dishwashers - has breakpoint releasing excess pressure into main wash container
Inventor: BARTHEN GERD
IPC: A47L15/42
Filed: 1976-03-09
Abstract: Water softening mechanism in dishwashers includes a salt container (1) for preparing the salt solution and a softener container (2) located in the water supply wherein an ion exchange is carried out to regenerate the contents through the measured supply of the salt. The closure (5) to the salt container has a break point preferably in the form of a reduction in the wall thickness which responds to the intermal pressure. In this way any excess pressure which may occur over the closure to the salt container can be blown without danger into the machine container. Since in the case of a reduction in the wall thickness the closure would have to be replaced if the excess pressure had caused it to blow it is possible to replace this break point by a valve-type insert which can then be reset.

Title: Profiles of chromium or special alloys - are extruded from ingot enveloped for protection against surface damage
Inventor: ESSEL OTTO DIPL ING
IPC: B21C23/00
Filed: 1976-06-01
Abstract: The tubes or other profiles are made from chromium containing alloys or special alloys by extrusion. The ingot is enveloped hermetically with a metal envelope. The surface of the Cr alloy ingot is protected on heating to the extrusion temp. and during the extrusion against oxidation and also against carburising by the lubricant. The extruded profile is protected also on cold forming an on heat treatment against surface damage by scaling, carburising and by the tools. The extruded material together with its deformed enclosing envelope is cold finished and subjected to intermediate heat treatment. The enclosing envelope can be stripped mechanically by conventional means or by pickling. Before the ingot is welded into the sheet metal envelope the contacting surfaces of the sheet and the ingot are cleaned by grinding, fettling, heating or by pickling. This method can be used for making solid or hollow profiles from ingots produced by powder metallurgy.

Title: Magnetometer with inductance coil - has preamplifier whose input impedance is matched to coil impedance to reduce voltage noise
Inventor: KARMANN RUEDIGER DR
IPC: G01R33/028
Filed: 1976-06-10
Abstract: The magnetometer consists of an induction coil with a highly permable core and a copper winding, and of a preamplifier with semi-conductor components.
