Title: A method and an arrangement for determining the height position of an electrode.
Inventor: BRUNNER MIKAEL
IPC: G01B7/02
Filed: 1996-04-18
Abstract: An arrangement for determining the height position of a vertically movable electrode (2) in an arc furnace (1).

Patent MX-9800038-A (MX)
Title: Heat treatment of carbon materials.
Inventor: LYNUM STEINAR
IPC: C01B31/04
Filed: 1996-07-05
Abstract: The invention concerns a method for heat treatment of carbon materials and especially carbon black in a plasma process for increased order in the nanostructure, i.e. an increased degree of graphitization in the carbon black particles. The process consists in an upgrading of commercial carbon black qualities and non-graphitic carbon materials. The heat treatment is conducted in a plasma zone where the residence time and power supplied are controlled in order to ensure that the carbon material does not sublimate. Thus the carbon which is supplied to the plasma zone is prevented from being transformed and reformed into a new product.

Title: System and method for detection and selection of multiple antenna.
Inventor: JAMES H THOMPSON
IPC: H04B7/15
Filed: 1998-05-13
Abstract: A system and method for selecting and combining satellite communication signals from multiple antennas. The system includes at least two signal paths (550A, 550B), each coupled to a separate antenna (202A-202N), and a combiner (430) for combining signals from the two paths for processing by a signal processor (216). At least one of the two paths (550A, 550B), includes a signal delay unit (410A-410B). The signal processor (216) can distinguish a signal received from a source on one of the antennas (202A-202N) from that signal received from the source on the other antenna based on a signal delay produced by the signal delay unit (410A, 410B). Each signal path (550) includes a variable attenuator (526) for selectively coupling each signal path (550) to the signal processor (216). The signal processor (216) determines the quality of the signals received along the signal paths (550), and provides data regarding signal quality to a control processor (220), which manipulates the attenuators to couple the signal path (550) having the highest quality signal to the signal processor (216).

Patent NL-7506526-A (NL)
Title: Variable voltage transformer - with impedance coupled brushes sliding on tracks with alternating conductive and insulated sections
IPC: H01F29/06
Filed: 1975-06-02
Abstract: A variable -voltage transformer has two sets of brushes, coupled by impedances, which slide along two bared tracks on one of the windings at right angles to the direction of the turns. The bared sections are arranged in an alternate pattern so that when one brush stands on a bared part, the other stands on an insulated part, with a changeover at the next turn. This eliminates the short-circuiting current caused by brushes bridging over the gap from one bared section of one turn to the next. Premature damage to the brushes is also prevented.
