Patent CA-1306047-C (CA)

Abstract: 53,663 ABSTRACT OF THE DISCLOSURE Long   conductors   which  interconnect  control pushbuttons such as STOP, START and RESET pushbuttons to the basic control circuit for an electromagnetic contactor or controller often have distributed capacitance between parallel lines in a common cable.  This distributed capaci-tance may conduct capacitive current from the power supply line to a parallel control line the control pushbutton of which is in the off state.  However, this latter current interacts with high impedance in the control circuit for producing a voltage which may be of a magnitude which would otherwise be supplied by an ON pushbutton.  A microproces-sor periodically samples the voltages and may mistake the False  signal due  to  the  capacitive current for  a true signal which would be caused by an ON pushbutton.  In order to discriminate between a TRUE signal and a False signal the first capacitor is connected between the power supply conductor  in  system  common  and  a   second  capacitor  is connected between a signal  conductor and system common. The capacitance value of the first capacitor is deliberate ly made smaller than the capacitive value of the second capacitor so that under normal circumstances the alternat-ing voltage on the second conductor logs the alternating voltage on the first conductor by an amount ? except when the voltage on the second conductor is provided by the aforementioned  distributed  capacitive  leakage  current between long lines in which case the voltage on the second conductor will lead the voltage on the first conductor by 66                  53,663 an amount ? due to the capacitive nature of the current which causes it.  The microprocessor therefore is condi-tioned to look at the two voltages immediately after the voltage on the first conductor changes state.  If at that time the voltage on the second conductor is of the same digital plurality as the voltage on the first conductor then the signal on the second conductor is a true signal indicative of a closed pushbutton.  If however it is not then the signal on the second conductor is a false signal indicative of the flow of capacitive current between lines rather than a closed pushbutton.

Granted: 1991-04-09
Abstract: Abstract of the Disclosure An article of knock-down furniture that can be easily assembled by an end-user comprises a plurality of pieces and contact joint arrangements that prevent unwanted separation of the pieces, while permitting the pieces to rotate and flex relative to each other.  The contact joint arrangements also have lateral flexibility to permit the pieces to be coupled and shaped into a contour.  The contact joint arrangement has a flexible tube that is extended through a continuous bore through each of the pieces.  A hanger bolt is threaded into each end of the tube.  A cap nut is threaded onto each hanger bolt and is in bearing contact with the end pieces.  Each of the cap nuts are tightened against the end surface of the end pieces in order to place the tube in tension.  The pieces are, consequently, held in longitudinal compression between the two cap nuts, while remaining free to rotate about the longitudinal axis of the tube. The hanger bolt and cap nut arrangement can be replaced by a screw assembly threaded into each end of the tube and contacting the end surfaces of the end pieces.  The screw assembly in one end of the tube is threaded into the tube through a hole or notch cut near the particular end of the tube.         Once the screw assembly has been engaged through the hole or notch, the excess lead portion of the tube can be separated from the tube.  Additionally. the screw assembly, or the hanger bolt and cap nut arrangement, at one end of the flexible cube can be replaced by a restraining element situated in fixed relationship with the tube. such as a molded stop or a cotter pin inserted through a transverse hole in cut one end of the tube.

Title: Apparatus for indirect dental machining
Inventor: LORAN WILLIAM
IPC: A61C13/38
Filed: 1989-06-07
Granted: 1993-11-09
Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for machining a human tooth includes a rotary cutter that is moved along a predetermined path dictated by motor energizing signals. The cutter is moved vertically by one drive, laterally by another drive and in or out by a third drive. The apparatus is clamped selectively to the patient's jaw or to a model thereof. The dentist's manual work is actually done on a model, with the apparatus being secured to the model in a fixed position. The vertical drive, the lateral drive, and the in or out drive are energized in response to the dentist's manipulation of a joy stick to move the cutter along paths necessary to achieve the desired tooth configuration. A second joy stick is manipulated to vary the attitude of the cutter, about roll and/or pitch axes. Signals proportionate to the extent of each drive operator are delivered to a computer in the sequence and for the period during which the drives are activated. When the machining is completed on the model, the restoration is prepared from the model, and the patient is then called back. The device is then secured to the patient's jaw so that it is in precisely the same relative position as on the model. Then, the computer delivers signals to the appropriate drive motors to repeat the appropriate machine strokes in the proper sequence to duplicate the machining previously done on the model.

Abstract: ABSTRACT           MEASUREMENT OF CAPACITANCE AND PARAMETER RELATED THERETO         A displacement-measurement apparatus includes a primary electrode, and first and second secondary electrodes which are closely spaced apart and together fully span the primary electrode, the primary and secondary electrodes being movable relative to one another without increasing their transverse separation.  A charge pumping means is arranged to supply electric charge to the primary electrode through the first secondary electrode during selected first clock periods, and to withdraw charge from the primary electrode through the second secondary electrode during selected second clock periods.  The changeover from one mode of operation to the other is made automatically when the sign of the charge on the primary electrode reverses, so that the charge on the primary electrode is successively increased, and then reduced to a low value.  The numbers N1 and N2 of charge packets supplied to and withdrawn from the primary electrode during a measurement cycle are counted, and a displacement signal is produced in accordance with the relationship (N1 - N2)/N1.  The electrical system may also be used for determining in a similar manner the ratio of the capacitances of any two capacitors.

Abstract: In a method of measuring velocity gradients in a sample volume (2) in a flowing medium, by which method radiation scattered by particles entrained by the medium and irradiated by spatially coherent electromagnetic radiation, in particular laser light, is detected and measured and the difference in Doppler shift in the radiation from different particles in the sample volume (2) used as a measure of the velocity gradient, an optical element (3) is inserted in the radiation path from particles in the sample volume (2) to the detector (4). The optical element (3) has such properties that essentially only radiation scattered simultaneously from particle pairs in the sample volume (2) spaced apart a distance determined by the optical element (3) are made part of the measuring signals to be combined to form the signal which is a measure of the difference in the Doppler shifts and thereby of the velocity gradient in the sample volume (2) defined by the measurement points. The optical element (3) may for example be an optical grating of the absorption, phase or reflection type or intermediate forms, a birefringent element, a Bragg cell, a combination of a totally reflective surface and a beam splitter or possibly a glass plate having one of its surfaces coated with a totally reflective material. The apparatus comprises a source for electromagnetic radiation (1), a detector (4) for receiving radiation scattered from particles in a sample volume (2), means for recording the output signals from the detector (4) and an optical element (3) of the above-mentioned type defining the position of a relevant particle pair.
