Patent CA-1140984-A (CA)
Inventor: LEVEILLE GILLES RUE MERCIER DR
IPC: H02K25/00
Filed: 1980-05-07
Granted: 1983-02-08
Abstract: An electric motor comprising a rotor rotating around an axis and a stator. The rotor and the stator each comprise a set of dipolar pieces regularly distributed around their respective periphery, one of these sets being inside a circle centered on the axis, the other set being outside of the same circle. Each of these sets has a different number of dipolar pieces. The motor further comprises a controlling system associated with one of the sets, preferably the stator, to furnish current coils wound on the dipolar pieces of this set so as to selectively magnetize these pieces and thus form a rotating magnetic field. In accordance with the invention, each dipolar piece has a longitudinal axis extending perpendicular to a given radius of a circle lying in a plane perpendicular to the axis of the rotor. The dipolar pieces are spaced so that the magnetization of one of the pieces of the set associated with the controlling system induces, with one piece of the other set, a magnetic circuit near the longitudinal axis of the pieces. This magnetic circuit seeks to close itself and thus induces a lever force which starts the rotor rotating. The resulting motor has fewer losses and can have a lighter structure than those already known.

Abstract: ABSTRACT    A method and composition for non-destructive testing of a magnetizable workpiece in which the surface of the workpiece is coated with a composition containing discrete magnetic particles consisting of a ferromagnetic particle core, fluorescent pigment particles attached to said core and a cascading opacifier combined therewith, preferably by means of a film-forming encapsulating resin.  The particles of the daylight fluorescent pigment are suffi-ciently large so that they fluoresce with sufficient in-tensity to be seen in normal lighting conditions.  Con-sequently, the magnetizable pieces to be inspected can be simultaneously inspected under ultra-violet and white light excitation to reveal both fine cracks and large voids.

Abstract: OPERABILITY VERIFICATION FOR SEGMENTAL ELECTROMAGNETIC DISPLAY Abstract of the Disclosure In fuel dispensing apparatus utilizing seven-segment electromagnetic displays each segment of all the displays is operatively driven and tested seriatum both prior to and during the dispensing cycle by measuring the current flowing therethrough.  Where peak current through each segment coil exceeds a predetermined switching value within an allotted time period, an inactivating signal is emitted via a microprocessor to inactivate the drive for the re-spective segment.  Failure to receive one or more of the inactivating drive signals per display represents a display malfunction which via the microprocessor renders the dis-pensing apparatus inoperable.

Abstract: ABSTRACT OF THE DISCLOSURE         In a heating apparatus equipped with a sensor element sensing or estimating the state of a substance being heated, for example, a temperature probe containing a temperature sensor such as a thermistor in one end of a metal tube or a humidity sensor sensitive to vapor emanating from the substance being heated, an information data suggesting a hint to the handling of such a sensor element or instructing an appropriate heating sequence or process selected on the basis of the sensed state of the substance being heated is selectively read out from a voice data memory to be synthesized into voice information in a voice synthesizer such as a PARCOR synthesizer, and the voice information is announced to the user at a predetermined time.  The user hearing the message can therefore manipulate the apparatus in such a way as to compensate for the inherent defect of the sensor element, and a menu requiring a very delicate procedure can even be successfully cooked without any failure of heating.

Abstract: ABSTRACT OF THE DISCLOSURE A close-wound coil spring moves a driven member in response to move-ment of a drive member. The spring is moved when one end thereof receives trans-verse force from the moving drive member; the other end of the moving spring transversely applies force to the driven member. If the transverse forces on the spring are less than a given amount, as when the driven member moves relatively slowly, the spring acts as a rigid lever capable of moving the driven member syn-chronously with, and during the same time interval as, the drive member. If the transverse forces on the spring exceed the given amount, as when the driven member moves suddenly or at high speed, the spring flexes according to Hooke's Law and moves the driven member asynchronously with, and during a different time interval from, the drive member. In the latter case, the spring's flexure limits the force applied to the driven member, preventing damage thereto.
