Title: Electroslag remelting system - with screened electrode by light-weight disc floating on slag for better thermal efficiency
Inventor: RABINOVICH V I
IPC: C22B9/18
Filed: 1975-11-07
Abstract: In an electroslag remelting process the electrode is screened only after the slag has become liquefied and a molten pool of metal has been produced. A disc with a central hole for the electrode is lowered on the surface of the bath so that it floats on the slag without touching the molten metal. The material of the disc has a lower density than the slag but a better conductivity. This improves the efficiency of the electroslag remelting process because the heat produces is entirely used for melting the electrode and heating the bath. The oxidation of easily oxidisable elements in the metal is eliminated.

IPC: F16H1/28
Filed: 1976-11-08
Abstract: A play-free planetary drive includes a sun gear and an internal gear between which planetary gears revolve as they rotate. The planetary gears are slightly beveled. The sun gear and the internal gear also are beveled, so that the bevel of the sun gear and of the internal gear match that of the planetary gears. With this arrangement of the gears, the sun gear and the internal gear are urged axially against the planetary gears, meshing into them until play has been eliminated. The internal gear is non-rotatably mounted to the housing, but is permitted to shift slightly radially to accommodate radial run-out of the planetary gears. Likewise, the sun gear is permitted to shift slightly radially to accommodate radial run-out of the planetary gears. The radial accommodation thus provided achieves a degree of load equalization among the planetary gears.

Title: Solar energy system for domestic warm air heating - has reversible air flow under collector panel preheating air or cooling panel and ventilating house
IPC: F24S10/50
Filed: 1977-03-03
Abstract: The collector panel has a face exposed to the sun and a face directed inwards of the building on which it is installed. The panel heats a thermal energy store in the building via a heat-carrying fluid circuit. Air passes through the store to heat the building and the air supply to the store is linked with an air circulation over the lower face of the panel. Pref. the panel forms part of the roof of the building, and a chimney leads from the lower part of the store to the lower part of the panel. As heat losses on the underside of the panel are to the heating air, the need for thermal insulation beneath the panel is removed. In summer, heat transmitted to the air beneath the panel causes it to rise, thus drawing air up the chimney. This avoids overheating of the panel and also serves to ventilate the building.
