Patent CA-2094552-A1 (CA)
Inventor: ANDERSON KEVIN J
IPC: H02P23/00
Filed: 1993-04-21
Abstract: In a drive using an AC induction motor for moving a load in hoisting and lowering directions, a method for determining motor speed includes, in any order, the steps of selecting first and second voltage signals representing a maximum speed to be attained by the motor at rated output torque in the hoisting and lowering directions, respectively, and selecting a bias voltage. One of the voltage signals is combined with the bias voltage to obtain a feedback signal representing motor speed and the feedback signal is compared with a speed command signal to obtain a deviation signal representing the difference between actual and commanded motor speed. The drive is disabled if the difference is "out of" a predetermined range.

Title: Methods of using ion trap mass spectrometers
Inventor: WELLS GREGORY J
IPC: H01J49/42
Filed: 1993-05-28
Abstract: IMPROVED METHODS OF USING ION TRAP MASS SPECTROMETERS                 ABSTRACT OF THE DISCLOSURE         Improved methods of using an ion trap mass spectrometer, whereby AC voltages supplemental to the AC trapping voltage are used for scanning the trap, for conducting chemical ionization experiments, and for conducting MSn experiments, are shown.  In one embodiment a broadband supplemental AC voltage is applied to rid the trap of ions above or below a preselected cutoff mass. This is particularly useful in conducting chemical ionization experiments for eliminating high mass sample ions that are formed when the reagent gas is ionized by electron impact ionization.  Likewise, this technique may be used to eliminate low mass reagent ions when conducting an electron impact ionization experiment in the presence of a reagent gas.  In another embodiment a non-resonant, low-frequency supplemental voltage is applied to the trap causing trapped ions to undergo collision inducted dissociation.  Multiple generations of ion fragments may be simultaneously formed in this manner, thereby enabling MSn experiments.  The low-frequency supplemental field has the additional property of causing high mass ions to be ejected from the trap as a function of the magnitude of the supplemental voltage. This property may be used to scan the trap, for example, by scanning the magnitude of the supplemental voltage. Likewise, when conducting chemical ionization experiments, this property may be used for eliminating unwanted high mass sample ions, formed during ionization of the reagent gas, from the trap.

Patent CA-2106008-A1 (CA)
Title: Micturitional assist device
Inventor: FANG ZI-PING
IPC: A61N1/05
Filed: 1992-03-10
Abstract: Cuff electrodes (40a, 40b) are surgically implanted around S3 sacral ventral root nerve trunks (16a, 16b). The sacral ventral roots have smaller diameter nerve fibers (20a, 20b) which convey action potentials to cause detrusor activation to contract the bladder (10) and larger diameter nerve fibers (18a, 18b) which carry action potentials for causing contraction of a urethral sphincter (12) to block the flow of urine from the bladder. A current source (50) causes current pulses (52) between such electrical contacts (46, 48) and a central electrical contact (44). The current pulses have an appropriate amplitude and waveform to initiate action potentials adjacent the central contact and to block the propagation of action potential adjacent the end electrodes along the larger diameter nerve fibers (which have fewer nodes between the contacts) but not the smaller diameter nerve fibers (which have more nodes between the electrodes). In this manner, action potentials are electrically excited to propagate at least downstream on the smaller diameter nerve fibers causing contraction of the bladder. Concurrently, blocking action potentials are allowed to propagate upstream on at least the larger diameter nerve fibers, collision blocking naturally occurring action potentials propagating downstream. The transmission of action potentials downstream on the larger diameter nerve fibers is blocked by the current pulses allowing the urinary sphincter to relax.

Title: Frequency Stabilizer for Use in Phase-Shift Keying Radio Communications System
Inventor: ISHII JUNICHI
IPC: H03L7/00
Filed: 1993-10-12
Abstract: A frequency stabilizer for use in a time-division multiplexed digital cellular system is designed to reduce the consumption of electric power by means of a receiving circuit in continuous frequency control.  The frequency stabilizer includes a pair of latches 4 and 5 for latching a phase error of an output signal from a phase error integrating circuit 2, a subtractor 6 for outputting the difference between respective output signals from the latches 4, 5, and a selector switch 8 for selecting and outputting an output signal from a phase-to-frequency converter 3 in the period of a reception slot and an output signal from a frequency correcting circuit 7 between reception slots.  When the selector switch 8 is selecting the output signal from the frequency correcting circuit 7, no electrical energy is supplied to the receiving circuit.  Even when the frequency stabilizer is in continuous operation, the receiving circuit operates only during the reception slot, resulting in reduced consumption of electrical energy.

Inventor: DIXON WILLIAM L
IPC: B24B9/14
Filed: 1993-11-23
Abstract: In accordance with the invention a holder is provided for an eyeglass frame having a pair of lens rims spaced apart by a bridge. A pair of supports are fixed in spaced apart relationship on a base plate and a cradle is journalled between the supports to rock beneath an axis spaced from and parallel to the base plate. A pair of jaws transversely mounted on the cradle in relation to the axis is biased toward closing and has a mouth accessible from above the axis. One or both of the jaws inwardly tapered from the mouth to a narrow passage and outwardly tapered from the narrow passage to a throat. The throat has inwardly extending seats. Thus, when a frame is inserted transversely into the mouth toward the throat with its upper rims against one of the jaws and its lower rims against the other of the jaws, the jaws open against bias to pass the frame through the narrow passage and then close under bias to secure the frame in the throat and on the seats. Preferably, the seats are aligned on the jaws so as to support the frame substantially along a plane parallel to the base plate when the cradle is in a normal angular orientation with respect thereto and to support either of the rims substantially along that plane when the cradle is rocked to left or right angular orientations with respect thereto.      The cradle is preferably journalled snugly enough to be frictionally secured in its normal, left or right orientations as desired. A tongue extending from the cradle is biased for reciprocal motion between the jaws and to extend from beneath the throat toward the narrow passage to center the frame transversely across the axis while the frame passes through the narrow passage to the throat.
