Title: Electric insulator with controlled surface conductivity - uses implantation of volumes of ions close to surface
Inventor: SCHMIDT CONRAD DR RER NAT
IPC: H02G5/06
Filed: 1976-06-04
Abstract: A treatment increases the conductivity on the surfaces of insulators. The insulators may be made from an inorganic materials such as for example epoxy resin, other cast resins etc. and from a mixt. of the two materials. The desired surface conductivity is achieved by controlled implantation of volumes of ions (A2, A3) close to the surface. The specific surface resistance of encapsulated gas insulated equipment for high voltage direct current switch gear can be approximately 1 megohm or higher. The value of the surface resistance can be set by varying the intensity and the energy of the beam of ions.

Patent DE-2711071-A1 (DE)
Inventor: JANGG GERHARD PROF DR
IPC: C22C1/10
Filed: 1977-03-14
Abstract: In the process for the preparation of Cu materials dispersion-hardened with oxides, mixtures of lumpy or pulverulent elemental Cu with powders of non-noble metals or lumpy or pulverulent alloys of Cu with non-noble metals are thoroughly milled under an oxidizing atmosphere and the milled products are subjected to a heat treatment under inert gas (diffusion annealing) and finally compacted. In this process, it is found, surprisingly, that the absorption of oxygen takes place very rapidly even at room temperature as a result of the surface continuously regenerated during milling. Possibly after a subsequent reduction to remove excess oxygen, the milled products are finally shaped in a conventional manner, for example by extrusion, powder rolling, forging, etc., to give compact workpieces.

Title: Smelting metal oxide compacts in shaft furnace - using non-coking carbonaceous reductant and controlled combustion conditions
Inventor: REHDER JOHN EDWARD
IPC: C21B11/02
Filed: 1978-03-31
Abstract: Compacts are formed from a mixture of metal oxide, solid carbonaceous matter of low volatile matter content, flux and binder, the carbon content exceeding that required for complete redn. of the metal oxide by the amt. desired for combustion. The compacts are charged to a shaft furnace where the excess carbon is burnt by air introduced through primary tuyeres located near the base of the shaft. The combustion conditions are such that no raceway or cavity is formed at any tuyere, that the space velocity of the combustion air referred to the emply shaft at normal temperature and pressure is >200 ft/min. and that primary combustion is predominantly to CO2. Oxygen contg. gas may be introduced independently through auxiliary tuyeres at a higher level to burn carbon monoxide. The invention is directed partic. to the reduction of Fe-bearing material, either ores or furnace dusts. It reduces costs by eliminating the need for coke and using instead non-coking materials. The low volatile content of the latter aluminates clogging of the upper part of the furnace by tar condensation.

Title: HV alarm device for construction workers - uses semiconductor field detector coupled to fail=safe audible warning unit
Inventor: KUEHNE BERND
IPC: G01R19/155
Filed: 1978-03-31
Abstract: The high-voltage detector comprises a flat probe (20) constructed from a flat circular foil of flexible material (21) on both sides of which are conductive or semiconducting layers (22, 23). Connecting lugs (24, 25) are attached to the foil before the layers are deposited. The probe is intended for universal use and may be attached to the clothing of construction workers, for example. The probe is connected to an amplifier and the voltage proportional to the electric field generated by the high voltage, is amplified and detected. The demodulated voltage controls a multivibrator. This in turn drives an audible warning device. As the warning device is battery-operated, an auxiliary circuit provides a continuous alarm signal if the battery power is below a safe level.
