Patent DE-1937694-A1 (DE)
Title: Vacuum degassing and casting molten metal
Inventor: BERNARD GERO JOHN
IPC: B22D18/06
Filed: 1969-07-24
Abstract: Method of tapping steel from vacuum degassing units comprises exerting on the metal in the discharge passage at the bottom of the degassing vessel a downward electromagnetic force greater than the difference between the vacuum pressure head, given by the pressure differential within and outside the degassing vessel, and the ferrostatic head, thereby allowing the metal to flow from the vacuum chamber. The electromagnetic force applied is variable to ensure that the discharge passage always contains metal, thereby maintaining the vacuum seal, and to be responsive to the ferrostatic head so that at all times the sum of the ferrostatic head and electromagnetic force are greater than the vacuum pressure head, the latter being greater than the ferrostatic head. In this manner the metal discharge rate can be effectively controlled. The system claimed eliminates the need for barometric legs and is simpler in construction, relatively inexpensive, reduces heat losses and allows degassing of all but a few pounds of molten metal.

Title: Filling material for polyolefin-insulated cables couplings - adheres well, is easily removable and does not alter electrical mechanical props.
Inventor: KLEEBERG WOLFGANG DR
IPC: H01B3/42
Filed: 1973-09-19
Abstract: Filling matl. having regulatable dielectric constant for polyolefin-insulated communication cable bundles and for cable couplings consists of viscous or gel-like polyadduct or polymer matrix which adheres to the surface of the cable/coupling voids and which contains embedded solid filler whose dielectric constant is less than that of the matrix. The matl. overcomes problems in this field such as long-term diffusion of components into the insulation (which alters cable' parallel speech capacity gives rise to electrical incompatibility when joining different old cables), discontinuous adhesion of filler to the insulaton (which allows ingress of water with all its associated problem) and flexibility (cf. GB 1006897, 1046314; US 2507508; DS 1490621; DT 1540407, 1690095, 1936871-2). This, by contrast, adheres sufficiently well to prevent water seeping in yet may be removed from the coupling without damaging or removing any print, is easily applied and doesn't alter a cable's mechanical props.

Title: Arc welding power supply - from high-frequency converter to separate magnetic amplifier and rectifiers for each welding point
Inventor: KEVE THOMAS DR
IPC: B23K9/10
Filed: 1973-11-07
Abstract: A d.c. arc welding current source consists of a 3-phase a.c. motor driving a high-frequency synchronous generator. A magnetic amplifier with control windings, which can be remote controlled by the welded, feeds a three-phase rectifier to produce the d.c. electrode current. An additional welding point duplicates the magnetic amplifier and three-phase rectifier. This control system does not affect other welding circuits (as in systems with current-dividing resistors) when one circuit is being adjusted. An asynchronous motor (2) drives through a coupling (3) a 300 Hz synchronous alternator (4). Its output is passed to a magnetic amplifier (6) which can be remote controlled by a unit (9) at the end of a line (8). A 3-phase rectifier (7) supplies the current fro the electrode (11). A second welding point (11A) is linked by a transmission line (14) to the generator output line (5); it includes another magnetic amplifier (6a), control unit (9a) and rectifier (7a).
Patent DE-2357510-A1 (DE)
Title: Mechanical damping system for tubular busbars - comprises offset masses flexibly coupled at two points to the busbar
Inventor: STIEFF RUDOLF
IPC: H02G5/00
Filed: 1973-11-17
Abstract: Masses are coupled to the busbar by a saddle with an elastic connection between the saddle and the centres of gravity. A second flexible connection, typically a cable, joins the masses to a second saddle clamped some distance along the busbar. If the bar attempts to vibrate the masses are set in motion and they twist and flex the cables. The friction in the cable transforms the vibration energy into heat to provide damping. The resistance of the cable can be chosen to give the correct damping. If there is more than one cable, then by selection of resistance the range of frequencies which can be effectively damped can be extended.
