Title: Methods of investigating ground faults particularly on induction furnaces
Inventor: SMALLEY DANIEL SCOTT
IPC: G01R31/02
Filed: 1983-08-05
Granted: 1986-11-13
Abstract: Methods of investigation ground faults, particularly on coreless induction furnaces, using a computerised monitor which includes a first potential transformer connected across the coil and second potential transformer connected between one end of the coil and an electric ground. The relative location of a ground fault along the length of the coil is determined by computing the ratio of the transformer outputs. The monitor further includes a first current transformer in the coil power line and a second current transformer with melt bath ground. Internal ground faults are detected by computing the phase difference between the coil and ground currents. A graphic representation of the furnace is also generated to illustrate the location of the ground fault with respect to turns and yokes of the coil. The monitor also calculates liner wear by determining melt bath volume, which is inversely proportional to melt bath resistance, which in turn is proportional to coil resistance. If the furnace being monitored is provided with more than one coil, a differential current transformer is connected across each coil to detect the fault grounded coil when the transformer associated with the faulted coil exhibits a substantially non-zero output.

Abstract: PCT No. PCT/AT85/00046 Sec. 371 Date Jul. 8, 1986 Sec. 102(e) Date Jul. 8, 1986 PCT Filed Nov. 11, 1985 PCT Pub. No. WO86/02850 PCT Pub. Date May 22, 1986.The method relates to the production of a string (24) for a racket, particularly a tennis racket. The string is a known string, for example a gut string or a synthetic string. The conditioning of the string on a support (1), particularly a bobbin, is effected under a traction tension and the length of the string is kept constant. Thus, the elongation of the string under the traction tension effect when winding the string on the support (1) is conveniently between 5 and 15%. The stringing of the racket with the thus conditioned string (24) should be carried out in an interval of 60 minutes, but preferably 30 minutes, from the removal time of the string from its support (1). The relaxation of the string, i.e. the decrease of tension after the stringing of the racket, is considerably smaller with a string conditioned according to the invention than with a same string which has not been conditioned. Such relaxation reduction is particularly important with a polypropylene string.
