Patent CA-2101727-A1 (CA)
Inventor: DE VERTEUIL MICHEL M
IPC: G21C13/02
Filed: 1993-07-30
Abstract: QUALPROTECH INC.                    PATENT APPLICATION for a DUAL VALVE TRITIUM STORAGE AND TRANSPORTATION BED          ABSTRACT          Transportation and storage of tritium requires containers that are rugged to prevent the possible release of tritium in case of an accident.  This invention has two valves integral with the body of the container so that it cannot be damaged if the container strikes something or is struck by something.  The dual valve design (at the same end) allows for continuous flow through the unit, made possible by the design of the pressure vessel body. The tritium is transported and stored as a metal hydride through the use of a getter material.  It is driven from the container by heating it with heaters applied externally, internally or by means such as microwave or radio frequency.
Patent CA-2102087-A1 (CA)
Inventor: DOVEK MORIS MUSA
IPC: G11B20/10
Filed: 1993-10-29
Abstract: A contact magnetic  recording rigid disk file utilizes a magnetoresistive (MR)  sensor for reading data recorded on the disk.  The disk file may be of the liquid-bearing type of contact recording with the MR sensor supported on the trailing end of a carrier which rides on the liquid bearing. The performance of the disk file is enhanced by including means for minimizing the effect of a discovered baseline read signal modulation.  The modulation has been determined to be caused by variable cooling of the temperature-sensitive and temperature-elevated MR sensor by the disk, with the temperature variation being directly related to the variation in head-disk spacing caused by the waviness of the surface of the disk.  A filter may be incorporated into the read  signal  processing  circuitry  of  the  disk  file  to eliminate the modulation, the MR sensor may be designed to operate at selected parameters to minimize the effect of the baseline  modulation,  and  the  portion  of  the  carrier  in contact with the disk surface may be selected to have a length less than the period of the disk waviness so that it more closely follows the disk surface topography.

Title: Centrifuge with dual motor synchronous drive system
Inventor: CLARK RONALD L
IPC: H02P5/74
Filed: 1992-12-23
Abstract: A drive system (184) that coordinates the rotation of a first and second rotating element, the first element (50) carrying the second element (52). The drive system also having a first motor (66) and a second motor (72), both motors having at least two poles (PA, PB). A drive control mechanism (186) is electrically connected to the poles of the first motor and the second motor. As the drive control rotates the first motor at a fixed rate, the first and second motors exchange power whenever a phase error occurs between the first and second motors. This power exchange eliminates the phase error and keeps the second motor in synch with and operating at the same rate as the first motor.

Title: Method and circuit arrangement for measuring the depletion layer temperature of a gto (gate turn-off) thyristor
Inventor: HAUSWIRTH CHRISTIAN
IPC: G01K7/01
Filed: 1994-06-23
Abstract: A method and a circuit arrangement having a device for measuring the depletion layer temperature of a GTO are specified. In this case, a measurement current (I M) is impressed in the gate circuit, and the voltage (U GR) between the cathode and gate is measured, with an applied measurement current (I M), after the transient turn-off processes have decayed. This voltage (U GR) is at this time dependent on the depletion layer temperature of the GTO. It thus becomes possible to measure the depletion layer temperature directly on the element, that is to say without circuitous routes via a heat sink temperature and calculation of the thermal resistance or the like, and during operation, continuously, and in consequence to monitor and control the stress level on the GTO precisely.

Patent CA-2135384-A1 (CA)
Inventor: SNIDER PETER
IPC: G06F17/00
Filed: 1993-05-12
Abstract: The invention provides a route state filter (74) for a vehicle route guidance system for improved tracking of vehicle position with respect to a preselected route. A set of position possibilities are derived by comparing a measured vehicle position (28) to a data-base (30) containing data representing a map of roads, the possibilities corresponding to possible positions on the roads within an error region around the measured position. A route guidance module receives the position possibilities (70), checks their validity (72) and applies a filter to remove less likely possibilities (74). A current position is then selected from the remaining possibilities (76). An ON/ OFF ROUTE status Or the vehicle is determined by comparing the selected position with the selected route information in the database (35, 78). A distance-based filter is utilized to provide improved continuity in the route status determination. The route status is then used to set the system operating mode, and warnings are communicated to the driver (32, 86).
