Patent CA-2092452-C (CA)
Title: Adaptive signal modulation system
Inventor: CHETHIK FRANK
IPC: H04L27/36
Filed: 1993-03-25
Granted: 2003-02-04
Abstract: Digital signals are converted to phase and amplitude altered, periodic, analog signals and emplaced on an output link. The system is adaptive and includes a plurality of simple quadrature phase shift keying modulators, each modulator having a plurality of controlling digital inputs, the states of which determine which of a plurality of phase displaced signals will be outputted. A local oscillator provides a periodic sinusoidal signal to each QPSK modulator. Summing circuits combine the outputs of the modulators so as to produce a constellation of phase and amplitude-displaced output sinusoidal signals. A processor/mapper combination enables conversion of a first set of digital inputs to a different set of digital outputs in accordance with a control input. Thus, the processor enables the alteration of the constellation of outputs in accordance with a control input, which may be indicative of the condition of a transmission facility.

Title: Spinal rod coupler
Inventor: KOROTKO JOSEPH RICHARD
IPC: A61B17/58
Filed: 1993-05-12
Granted: 2004-04-27
Abstract: The coupler of this invention includes a two-piece coupler for a spinal rod including a yoke and a coupler body which may be positioned to clamp onto the spinal rod at an angle other than perpendicular relative to the rod. The yoke and body permit the spinal rod to be positioned plus or minus 15 degrees out of true perpendicular relative to the rod without sacrificing clamping strength. This advantage is particularly useful when the couplers are connected to a rod-to-rod interconnecting device to permit the rods to be less than parallel relative to one another.      The accommodation of less than parallel rods or the non-perpendicular connection of device to the spinal rods reduces the non-functional exact positioning of the spinal rods during surgery as is required by current couplers. Further, the coupler can be placed from a superior position requiring minimal space without the need for screws to provide fixation to the rod.

Abstract: An improved apparatus for delivering energy to two field applicators includes a power divider electrically coupled to a planar transmission line connecting the two Field applicators. The power divider receives an input microwave signal and delivers a first power signal to an applicator along a first leg of the line, and delivers a second power signal to the other applicator along a second leg of the line. The power divider is coupled to the transmission line at a point which is remote from the applicators such that the power signals will encounter substantially identical discontinuities as the signals are coupled into their respective applicators.

Granted: 2003-09-16
Abstract: Apparatus for dimming neon tubes and signs in which certain problems associated with high dimming levels (lowered illumination intensities), namely, of tube non-excitation and non-uniform illumination, are eliminated. The apparatus includes a generator for creating pulse groups, which groups consist of one or more high frequency, full-amplitude pulses and a modulator for selectively controlling the repetition rate of the pulse group and/or the number of pulses forming each group. The apparatus further includes ground fault interruption circuitry that is immune from the false triggering occasioned by the low pulse group repetition rate which in turn results in the repeated de-ionization/re-ionization of the neon gas.  The ground fault interruption circuitry includes a detector for establishing the initiation of a pulse group and an inhibitor to preclude ground fault interruption during periods of gas re-ionization following the commencement of each pulse group.

Abstract: An improved method for the preparation of saccharide fatty acid polyesters via an intermolecular transesterification reaction is provided. A saccharide lower acyl ester (for example, sucrose octaacetate) is reacted with a fatty acid lower alkyl ester (for example, methyl stearate) in the presence of an alkali metal alkoxide catalyst to produce a saccharide fatty acid polyester. The reaction is carried out at relatively low temperatures in the absence of solvent. The relatively low molecular weight by-product ester is removed from the reaction mixture during the course of the reaction in order to drive the equilibrium transesterification reaction to completion. The saccharide fatty acid polyesters are useful as fat substitutes or low-calorie fats in food compositions.

Title: Sliding element system
Inventor: SJOHOLM JARMO
IPC: E06B3/50
Filed: 1993-10-14
Granted: 2002-08-27
Abstract: An improved sliding element system is provided herein, which is of the type wherein the guide wheel sets of the lower side of the sliding element are designed to support the sliding element on a lower guide section. A vertical wheel set is connected to the lower side, the vertical wheel set comprising a vertical wheel, the diameter of which is smaller than the transverse inside dimension of the lower guide section, the plane of rotation of which is vertical. The peripheral cross section is round-shaped, and the point of contact with the lower guide section is located on the same vertical line as the central axis of the wheel axle. The lower guide section comprises a longitudinal, upward, open-bottom groove, the edges of which serve as rolling surfaces for the vertical wheel.  The vertical wheel and the bottom groove are mutually fitted so that, when the plane of rotation of the vertical wheel parallels the bottom groove, the vertical wheel extends partly into the bottom groove. When the sliding element is being swivelled at a hinging point to stand at an angle relative to the guide sections, the vertical wheel, which is disposed to be fixed in relation to the sliding element, will rise upwardly carried by the edges of the bottom groove. A first coupling member will then be coupled by form-locked connection with a second coupling member.

Patent CA-2155657-C (CA)
Inventor: VERGIN WILLIAM E
IPC: E05B47/00
Filed: 1994-02-10
Granted: 2003-04-29
Abstract: A linear drive, particularly useful for locking or unlocking a door lock mechanism or the like permits manual operation by providing an output shaft that can move freely regardless whether the output shaft is in extended or retracted positions without back driving the motor. The output shaft is coaxially slideably situated over a worm gear shaft which moves a nut that is threadingly engaged therewith and moves inside the output shaft along the axial direction of the worm gear shaft. The output shaft is not threadingly engaged with the worm gear shaft. The output shaft thus is freely movable relative to the worm gear shaft, which results in essentially zero back drive of the worm gear shaft and the motor. To provide for manual operation, the nut is automatically moved back to its neutral position every time the output shaft is extended or retracted by a torsion spring or the like which can store energy therein. Whenever the motor is operated to drive the worm gear shaft, the spring gear is also rotated, which causes the spring to store energy therein. As soon as the motor is turned off,the energy stored in the spring causes the worm gear to rotate in the direction opposite to the last motor driven direction to move the nut to the neutral position it was in prior to energization of the motor.

Abstract: A clamp for use to fix nonmetallic sheathed or armored cables within an electrical device box. This clamp has an L-shaped body with a forwardly projecting front wall and an upwardly projecting rear wall. The front wall has a central hole and a rectilinear front edge of a given length that is parallel to the rear wall. An integral U-shaped element projects from the front edge of the L-shaped body along the full length of it. Two upwardly embossed portions are made in the front wall. These portions are symmetrical with respect to the central hole and each has a semi-cylindrical cross-section with an axis perpendicular to the rear wall. Each embossed portion ends at a short distance from the rear wall and defines therewith a locking ridge. Two front openings are made in the front wall at the junction of the embossed portions with the front edge of the body. In use, fixation of the clamp within the device box with a screw inserted into the central hole of the front wall of the clamp allows one or two cables to be squeezed and thus be fixed either between the U-shaped element, the corresponding locking ridge and the adjacent wall of the box when the cable is of the nonmetallic sheathed type, or within one of the embossed portions when the cable is of the armored type.      Advantageously, a forwardly and downwardly projecting tab can be provided in the rear wall of the clamp, to retain the screw used to fix it into the device box.
