Title: Multipole circuit breaker with reduced operating temperature
Inventor: EBERTS WILLIAM G
IPC: H01H73/00
Filed: 1995-09-15
Abstract: At least one inner pole of a multipole circuit breaker is connected in parallel with another pole to reduce the current through the inner pole, and therefore, lower the operating temperature of the circuit breaker. In circuit breakers having electronic trip units, the current transformers providing sensed currents for the poles connected in parallel are connected to the trip unit in parallel. In circuit breakers having thermal-magnetic trip devices, the current/time characteristics of the thermal-magnetic devices associated with the poles connected in parallel are set so that they collectively substantially match the current/time characteristics of the other poles. A four pole breaker can be connected in a three conductor distribution system by connecting the two center poles in parallel to one conductor, and connecting each of the other two poles to a different one of the remaining conductors. One inner pole and the adjacent outer pole can be connected in parallel to one conductor in a two conductor distribution system, with the other inner and outer poles connected in parallel to the other conductor. In the two conductor system, the four pole breaker can be replaced by a three pole breaker having the center pole and one outer pole connected alone in parallel to one conductor and the other outer pole connected to the second conductor.

Title: Cold sterilant with extended active life
Inventor: LINDEMAN LORRAINE D H
IPC: A61L2/26
Filed: 1994-07-12
Abstract: Sodium perborate is mixed with a mixture, preferably a 1:1 mixture, of a rapid acetylating agent, e.g. TAED, and a slow acetylating agent, e.g. acetylsalicylic acid, in water to form a biocidally effective peracetic acid solution. When sodium perborate and TAED alone react in water, peracetic acid is produced quickly but has relatively little stability and a short useful life (curve 10). When sodium perborate and acetylsalicylic acid are mixed in water, the peracetic acid solution takes an extended duration to reach maximum efficacy, but is stable for an extended duration (curve 12). The mixture of rapid and slow acetylating agents quickly produces a stable peracetic acid concentration (curve 14).

Title: Interrogator assembly for system of identification by radio-detection
Inventor: CHEVALIER JEAN-PIERRE
IPC: G01S7/34
Filed: 1996-02-13
Abstract: The disclosure relates to the recognition of an objective known as an IFF or "Identification Friend or Foe" system.

Title: High density floppy drive with pulse-width modulation
Inventor: GARZA RICARDO R
IPC: G11B20/14
Filed: 1995-07-21
Abstract: A storage system for storing information on a magnetic media is embodied within a conversion device. The system is operable to store data within a bit cell by receiving data from a controller board (14), which data is generated by a CPU (52). This data is converted from an ordinary MFM format received on a bus (32) and then converted to a Super High Density (SHD) data format. In the SHD format, a counter is provided for counting down from an initial starting time corresponding to a reference pulse (102) to an end count value corresponding to the value of a data word. The time between the reference pulse and the end of count value constitutes the length of time from the beginning of the bit cell to the position in the bit cell at which a data pulse is recorded. During a decode operation, i.e. a Read operation, it is only necessary to determine the position of the data pulse within the bit cell with a counter that counts from the predetermined reference pulse to the position of the detected data pulse. This corresponds to a data value.  Therefore, a multiple bit data word can be encoded within a given bit cell.
