Title: A switched reluctance motor providing rotor position detection at low speeds without a seperate rotor shaft position sensor
Inventor: VAN SISTINE THOMAS G
IPC: H02P6/18
Filed: 1996-01-26
Abstract: A switched reluctance motor includes a rotor mounted for rotation about a rotor shaft axis and a stator surrounding the rotor and having at least three electrically independent stator phases.  The motor includes an electronic circuit for for selectively energizing the phases in succession with a run current to generate a torque on the rotor and thereby rotate the rotor. The circuit includes switch operating means for selectively operating switches connecting an energy source to the phases.  The circuit also includes current sensing means for sensing the amount of current in each of the phases, and timing means for determining the amount of time for the current in each phase to reach a predetermined current level threshold. The circuit also includes pulse means for periodically selectively operating the switch operating means for a limited time to energize the unenergized phases with a seek current without substantially generating torque on the rotor, and comparing means for comparing the amount of time that current in each of the unenergized phases took to reach the predetermined current level threshold. The circuit also includes run means connected to the comparing means and the switch operating means for switching on a selected one of the switches to rotate the rotor.

Patent CA-2173495-A1 (CA)
Inventor: CULVER KENNETH W
IPC: A61K35/76
Filed: 1994-10-04
Abstract: L'invention concerne un procédé pour traiter une tumeur dans un organisme hôte. Ce procédé consiste à administrer à l'organisme hôte au moins un véhicule d'expression comprenant une première séquence d'acides nucléiques codant un agent qui rend les cellules tumorales sensibles à un agent d'interaction, et une deuxième séquence d'acides nucléiques qui code un agent qui assure l'inhibition, la prévention ou la destruction de la croissance des cellules tumorales, ce dernier agent ne rendant pas les cellules tumorales sensibles à un agent d'interaction. La tumeur est ensuite traitée par l'agent d'interaction. De préférence, la première séquence d'acides nucléiques code un marqueur sélectif négatif (comme la thymidine kinase du virus Herpes simplex), et la deuxième séquence d'acides nucléiques code une cytokine (comme l'Interleukine-2), et les première et deuxième séquences d'acides nucléiques sont contenues dans des premier et deuxième vecteurs viraux, et sont eux-mêmes contenus dans une première lignée cellulaire productrice et une deuxième ligne cellulaire productrice, respectivement. Les lignées cellulaires productrices sont administrées à la tumeur, et, de ce fait, les particules virales générées par les lignées cellulaires productrices infectent les cellules tumorales. Les cellules tumorales sont tuées lors de l'administration de l'agent d'interaction, tel que le ganciclovir, à l'organisme hôte.

IPC: A47G21/06
Filed: 1994-09-02
Abstract: The invention relates to a bundle (40) of disposable cutlery implements (6) (knives, forks or spoons). The bundle (40) consists of a stable stack of nesting implements (6) secured together by a strip or band (42). The implements have a handle (8) and an operative part (10) (blade, tines or bowl). The handle (8) of each implement (6) has a roughly U-shaped cross section over its entire length. The two arms (14) and (16) of the U-section form a blunt angle with the web (18). At the end of the handle both arms are joined together also to form a blunt angle with the wall section (20) formed by the web. In order to be able to form large stable stacks of nesting implements of the same kind while reducing the volume of packaging material required, the two arms (14) and (16) of the handles (8) are extended beyond the transition (22) to the operative part (10) and gradually taper to merge with the edge thereof.

Patent CA-2177166-A1 (CA)
Title: Method and apparatus of staged resonant frequency vibration of concrete
Inventor: FACE SAMUEL ALLEN JR
IPC: E04G21/08
Filed: 1994-07-04
Abstract: Vibration energy introduced into plastic concrete structures, such as concrete slabs, decks and similar or related concrete structures, at or near the natural resonant frequency of the liquid concrete mass (M), expedites the consolidation and setting of the concrete. A vibrating apparatus (3) imparts controlled vibrations either onto the surface or beneath the surface of the concrete mass (M) in sequential stages, the frequency of vibrations generally increasing with each subsequent stage, corresponding to the increase in the natural resonant frequency of the progressively-narrowing liquid concrete (M2) at the top of the structure. The relatively more consolidated and more dry concrete (M1) (typically near the bottom of the slab) is substantially unaffected by the non-resonant frequencies. In one modification, sensors (5) determine the resonant frequency of the liquid concrete mass (M2) during each pass of the vibrator apparatus (3), and the frequency of the vibrating member (82) is automatically adjusted, accordingly. The number of stages, the amplitude of the vibrations, the physical orientation of the vibration-producing apparatus (3), the time duration in each stage, is variable depending upon the physical characteristics of the concrete mass (M2).

Patent CA-2180258-A1 (CA)
Title: A wireless digital synchronized diversity receiver
Inventor: WINSHIP PETER
IPC: H04L1/02
Filed: 1994-12-28
Abstract: A digital receiver (10) for receiving an RF signal has a conventional RF to intermediate frequency (IF) converter (14).  The IF signal however, is amplified with a limit on its amplitude (20).  In addition, a Receive Signal Strength Intensity (RSSI) signal is generated  (28). The RSSI signal contains the envelope information of the modulated IF signal.  The IF amplitude limited signal containing phase information is then digitized and a complex baseband signal is produced (68).  The complex baseband signal is then combined with the RSSI signal to restore the amplitude information of the modulated IF signal in the complex baseband signal.  The restored complex baseband signal can be equalized with a conventional equalizer (70) to remove intersymbol interference.  A conventional symbol detector (80) detects the symbol in this signal stream.

Title: Shoe having lace tubes
Inventor: ORECK ADAM H
IPC: A43C11/20
Filed: 1995-02-28
Abstract: This invention relates to a shoe having an ergometric shoe lace design. The laces pass through tubes on the tongue portion of the shoe and extend down to the sole of the shoe on either side of the shoe where they pass through tubes on or near the perimeter of the sole. The laces crisscross the foot in this manner to secure the foot from up and down motion in the shoe. Optionally the lace may continue to be wrapped around the heel of the foot through ankle tubes and heel tubes to secure the foot from toe to heel movement in the shoe. This is particularly of advantage for shoes used in sporting activities. In this manner the upper of the shoe is not pulled together on either side of the tongue as in conventional shoes, thus avoiding stresses in the upper that tend to put pressure on and rub against the user's foot. Thus the shoe is comfortably and securely held to the user's foot.
