Patent MX-9700344-A (MX)
Title: Circuit replacement lock.
Inventor: WETZEL UWE
IPC: H01H47/00
Filed: 1997-01-13
Abstract: The present invention refers to a replacement lock for a control device which serves to control and verify the essentially simultaneous energization of two electromagnets (61, 62) in response to a respective electrical signal (S1, S2) which is applied to said electromagnets in an essentially simultaneous way, each electromagnet including a non-energized means of the electromagnet taking a first inactive normal replacement, and which upon activation of said electromagnet is displaceable to a second active terminal position, wherein the control device is disposed so that the displaceable elements (71, 72) of both electromagnets (61, 62) can be moved to their respective active end positions in an essentially simultaneous way, and then remain in such end positions as long as both signals (S1, S2) are essentially simultaneously applied and maintained. Detecting means are provided to assess in each operative cycle of the control device that both control signals have been applied, and that the displaceable means of both electromagnets have been moved to their respective active end positions. The replacement lock is built to interrupt current supply to a control device when these conditions are not fulfilled
Patent MX-9702683-A (MX)
Title: Current shaping in reluctance machines.
Inventor: MCHUGH PAUL MALACHY
IPC: H02P25/08
Filed: 1997-04-11
Abstract: A current control circuit for a switched reluctance machine provides corner shaping at the end of the active conduction period of a phase in which the phase winding is energised. The pulse width modulated firing pulses are gradually reduced in duty cycle so that the transition between the current in the winding in the active period and the decay of current in a ramp down period is smoothed to reduce the forces leading to vibration and acoustic noise.

Patent NL-8301264-A (NL)
IPC: H04N1/419
Filed: 1983-04-11
Abstract: In a system for the line-wise compression of binary data of a picture field, a first series of data bits of a current picture line and a second series of data bits of the directly preceding picture line are shifted together into a compression translator (74). To this end, in a memory operation each time a word of a line memory is read in order to obtain the data of the preceding line; at the same time the same word is written in orderto buffer the data of the current line. At the output of the compression translatorthe serial compression bits are regrouped in orderto form words. Exclusively groups of significant compression bits are thus formed. For the decompression a code word is read and a series of data bits is emulated and encoded. When the code word thus found corresponds to the code word read, a next code word is read and possibly a change of value for the data bits to be subsequently emulated is introduced.

Patent NL-9301976-A (NL)
IPC: H04Q1/14
Filed: 1993-11-16
Abstract: A method for pulling wires by means of a pilot wire (24,25), in which ends of the pilot wire are fixed, makes it possible to keep re-using the pilot wire at one particular point, thus without the pilot wire always having to be re-installed. For this purpose, the pilot wire must either be considerably longer than the distance between the points where the ends are fixed, such as a pilot wire in the form of an elongated loop, or the pilot wire must be elastic. An elastic pilot wire also has the advantage that during the fastening of wires to the fastening point or detaching of wires therefrom, it is possible to deviate from the shortest conceivable line between the ends. <IMAGE>
