Title: Process for the preparation of acicular goethite
Inventor: SCHOLZ HEINZ DIPL CHEM DR
IPC: H01F1/06
Filed: 1981-08-17
Abstract: A suspension of an iron(II) compound which is sparingly soluble in water, in an alkaline liquid consisting essentially of water has air, oxygen or another oxidising gas or gas mixture passed through it. The goethite crystals or particles formed are filtered off, washed and dried. Particles more "monoenergetic" from the thermodynamic point of view than those prepared according to known technical processes are produced if the oxidising gas being passed through is interrupted for a while a number of times. This procedure is called "chopped oxidation"; it represents a gradient reversal method, as the concentration of the oxidant in the reaction medium periodically rises and drops again. <IMAGE>

Title: Method for manufacturing resistors withstanding high voltage
Inventor: NOEGEL OTTO DIPL PHYS
IPC: H01C17/065
Filed: 1981-09-01
Abstract: A method for manufacturing resistors withstanding high voltage is described, which have a critical voltage of at least 2000V and, by immersion, are coated with a resistive layer, capped and provided with a jacket. In so doing, in particular, a colloidal metal oxide, as a resistive paste containing an electrical conductor, is converted, by adding an aromatic compound serving as a diluent, into a glazing composition which is thixotropic at room temperature. Said thixotropy is then abolished by the glazing composition being agitated, and rod-shaped ceramic bodies are dipped into this glaze at room temperature, are predried and finally fired in a firing-in kiln and are then processed into individual capacitors.

Title: Proportional pressure valve for a hydraulic circuit
Inventor: MUNCKE LUDWIG
IPC: B60T8/18
Filed: 1981-11-26
Abstract: A description is given of a proportional pressure valve for a hydraulic circuit, the said valve having a differential pressure control piston which can optionally reduce a supply pressure in steps. For the stepwise alteration of the pressure reduction characteristic of the differential pressure control piston, the force exerted by the reduced pressure on the controlling end face of the pressure control piston is either taken by the housing or amplified in steps by alternatively fitting and releasing a switching piston. For this purpose, the switching piston is guided on the pressure control piston and can be moved selectively into force-transmitting bearing contact with a radial shoulder of the control piston by means of an actuating device actuable from the outside, which piston can be locked or released as desired by the said actuating device. The actuating device has two mutually opposite stepped pulleys, the axial mobility of which relative to one another is determined by the switching steps. For this purpose, the stepped pulleys have faces which are stepped in the circumferential direction on the mutually opposite sides and, by virtue of twisting of the stepped pulleys relative to one another, vary the free axial stroke and hence the freedom of motion of the pressure control piston and of the switching piston so as to bring about the various control characteristics.

Title: Building element comprising a hollow body which can be closed in an air-tight and vapour-tight manner by walls and rigid or movable closing components
Inventor: BECKER OTTO ALFRED DR
IPC: E04C3/29
Filed: 1982-05-26
Abstract: The subject of the present application is a building element comprising a hollow body which can be closed in an air-tight and vapour-tight manner by walls and rigid or movable closing components. According to the present invention, the individual elements - rectilinear tubes closing components - are combined by the addition of connecting components with projections, in particular to give rectangular frames whose individual tubes are tensioned in a flexurally rigid manner by expanding means. The connecting components are designed in such a manner that they allow the arrangement of further frames in any direction. As a result, large, in particular also three-dimensional, frameworks forming a structural skeleton of very high flexural and load-bearing strength, to which only panels to form walls, floors and ceilings have to be added, can be erected on site as required. The interspaces formed by the frame tubes are thus suitable for arranging highly efficient soundproofing and heat-insulating means. The invention further provides for tensioning bands, e.g. of steel, to be arranged on the frame tubes extending parallel to one another. These bands are tensioned as and when expedient, via the other frame tubes extending perpendicularly thereto, by means of projections which can be pushed out of these tubes by expanding materials. Wall panels can be outwardly and inwardly fastened to these straps. <IMAGE>
