Patent DE-2223179-A1 (DE)
Title: Steel making from scrap or sponge iron - by baking to electrode and continuously melting
Inventor: LUENIG HERMANN K DIPL ING
IPC: C21C5/52
Filed: 1972-05-12
Abstract: Shredded scrap and sponge iron are compressed to form a composite electrode for melting in an electric arc furnace. The raw materials are fed into a heat-resistant tube and compressed by a piston. Electrical current is fed via a shoe halfway up the tube to pre-heat and fuse the materials together. Power via a second shoe lower down strikes an arc between the electrode and the bath, so that the electrode is progressively melted. The vessel can be much smaller than the conventional arc furnace that has to accommodate a very large volume of scrap initially. The melted can also be combined with arc furnace refining and vacuum degassing.

Patent DE-2348993-A1 (DE)
Title: Induction unit for warm air heating - mixes room air with very high temperature primary air
Inventor: SIMMONS ROBERT SIDNEY
IPC: F24D5/02
Filed: 1973-09-28
Abstract: The unit has a primary air duct with vertical stub ducts each terminating in a nozzle. The nozzles are within the bell mouth of an air duct which stretches through an extension cross over piece to a discharge. An air inlet allows room air to reach the entry of the bell mouth. The inlet is at the bottom and the discharge at the top of the casing containing the entire assembly. The discharge of primary air through the jets entrains room air into the bell mouth so that it mixes with the primary air in the air duct. The mixture then passes into the room at a moderate temperature. Because the primary air can be at a higher temperature a smaller quantity is needed.

Title: Display device with pointer guided in curved slot - is pressure medium operated for measurement and control
Inventor: SAEMANN HANS
IPC: G01L7/06
Filed: 1973-11-02
Abstract: The pointer is guided by a curved slot in which its rearward end moves. It has further a spring bellows controlled by the pressure medium and connected with the pointer through a flexible cable and a lever system, whose end is the pointer. The end of the curved slot, corresponding to the pointer zero position, is widened. The pointer is spring loaded, so that its rearward end always slides on the same slot edge. The slot widening is transversal to the edge on which the pointer end slides. The guiding rod serving to move the end of the pointer in the curve has the possibility of moving to the side at the end of the curved pathway. This lightens the load on the flexible stress conducting organs as well as the positioning of the pointer and its activating level.
