Patent CA-2033014-A1 (CA)
Inventor: LEKHTMAN GREGORY
IPC: A61B5/22
Filed: 1990-12-21
Abstract: An elongate hollow cylindrical member houses electronic circuitry and has disposed on its surface, on either end, a live electrode and a spaced common electrode.      The electronic circuitry includes a difference amplifier, and electromyogram signals detected by the electrodes are applied to opposite polarity inputs of the difference amplifier. As the electromyogram signals are of substantially equal amplitude and phase, the electromyogram signals will be subtracted from each other in the difference amplifier to provide a substantially zero output due to electromyogram signals at the output of the difference amplifier. However, electrocardiograph signals, being of opposite phase, will be added in the difference amplifier so that the output of the difference amplifier is substantially due to only the electrocardiograph signal.

Abstract: HERMETICALLY SEALED SCROLL TYPE REFRIGERANT COMPRESSOR WITH AN IMPROVED LUBRICATING MECHANISM          ABSTRACT OF THE DISCLOSURE       A hermetically sealed scroll type compressor includes a lubri-cating mechanism. The compressor includes a hermetically sealed housing and a motor driven drive shaft supported by a plurality of plain bearings in an inner block member. The drive shaft is provided with pin member at its upper end. The axis of pin member is radially offset from the axis of the drive shaft. The pin member is opera-tively connected to an orbiting scroll which orbits within a fixed scroll. A rotation preventing device prevents rotation of the orbiting scroll. The drive shaft includes an axial bore extending from a lower end thereof to a lower end of the pin member. A centrifugal pump is provided at a lower end of the axial bore, and immersed in the lubri-cating oil pump at an inner bottom of the housing.

Title: Cam-lock busway joint assembly
Inventor: ARN GARY D
IPC: C07D473/00
Filed: 1991-11-07
Abstract: ABSTRACT       A connector for electrically connecting a plurality of electrical conductors of a first busway section to a plurality of electrical conductors of a second busway section. The electrical connection is accomplished by a plurality of pairs of electrical joint connectors, each pair having an independently operable rotational clamping mechanism for clamping that pair of joint connectors tightly to corresponding electrical conductors of the first and second busway sections. An actuating cap is used to manually rotate the clamping mechanism between a first and second position. In the first position the pairs of joint connectors are clamped tightly to the busway conductors. In the second position the pairs of joint connectors are loosened permitting an easy insertion or removal of the busway conductors. The pairs of joint connectors of opposite polarity are separated from each other by a phase insulator. Phase insulators also separate the electrical phases from a protective enclosure surrounding the busway. The joint connectors, rotational clamping mechanism, and phase insulator are held in place by an electrically insulated frame comprised of two halves. The frame is held together by four assembly rods which pass through the two halves of the frame. A cover plate for closing a joint access opening in the busway protective enclosure locks the rotational clamping mechanism in its first position preventing it from rotating to its second position.
Patent CA-2055898-A1 (CA)
Inventor: LEWYN LANNY L
IPC: H02M3/07
Filed: 1991-11-20
Abstract: A positive energizing voltage is converted by a pair of buffer capacitors and a filter capacitor to a particular negative potential. Each buffer capacitor is charged during a half clock signal cycle, the first during positive half cycles and the second during negative half cycles. Each buffer capacitor discharges through a circuit including a switch which has at each instant a variable state of conductivity dependent upon the magnitude of the negative potential at that instant. This magnitude is varied in accordance with the variations in the state of the switch conductivity to regulate the negative potential at a particular value, as opposed to the magnitude changing, as is the tendency in prior art CMOS circuits. The filter capacitor is charged by the negative potential and is discharged to the load briefly during every change in the clock signal polarity.

Inventor: STEMMLER HERBERT
IPC: H02M1/12
Filed: 1991-11-25
Abstract: Process and device for eliminating or reducing harmonics and/or resonance oscillations An a.c. machine (7) with, connected in parallel thereto, a capacitor bank (CR, CS, CT), which are fed by a converter (1 - 4) with a d.c. intermediate circuit, form a resonant system which is excited by the rectangular current of an inverter (4) of the converter. In this case, there is superimposition of the fundamentals and the normal harmonics in the machine voltage and in the machine current of an additional harmonic with the frequency of the resonance point. In the lower speed range of the a.c. machine (7), this excitation is eliminated by an optimum operating sequence of current gaps, which are generated inside a current block by means of a quenching circuit (3).      Current gaps are generated at the start and end of each current block for the purpose of damping the 11th and 13th harmonic, and in the middle of the current block for the purpose of damping the 7th harmonic. A turn-on angle basic value signal (.alpha.M) is modified by a turn-on angle differential signal (.DELTA..alpha.M) for the purpose of damping the 5th harmonic, in particular an exciting or available harmonic being controlled to 0 or in the vicinity of 0.
