Patent CA-2020639-A1 (CA)
IPC: G01S13/90
Filed: 1990-07-06
Abstract: In a sensitivity time control device for an imaging radar system with an automatic gain control attenuator, a sensitivity time control attenuator and an analog-digital converter, output signals of the analog-digital converter are applied, via a device (20) generating an average value and a comparator device, to a control device, which has an on-off relay connected with a device for determining its control parameter, an integrating member, switched downstream. and a device for calculating the operating point of the automatic gain control attenuator device. Fur-thermore, an n-bit digital analog converter is switched downstream of the control device, by means of the analog output voltage of which the sensitivity time control attenuator is controlled. It is possible, with the aid of the sensitivity time control device, to evaluate continuously the backscatter signal of an imaging radar system in real time, so that it is continuously possible in this way to determine an optimal sensitivity time control curve.  By means of such an optimal sensitivity time control it is always possible to obtain the average value of the backscatter signal output independent of the range.

Patent CA-2022963-A1 (CA)
IPC: D06F34/08
Filed: 1990-08-09
Abstract: A control for an automatic washing machine with a reversing permanent split capacitor (PSC) drive motor.          Separate ferrite core sensors surround each of two PSC motor windings.  A sense winding is threaded through both sensors.          A brief output voltage is generated whenever the alternating current in either PSC motor winding passes through a zero-crossing and when the sense winding is wound with proper mutual polarity, an output voltage is generated in response to zero-crossings of a brief, residual alternating current which flows in both PSC motor windings and the capacitor when the rotating PSC motor is cycled OFF.  The circuitry, in combination with the sensors, samples the leading or lagging phase angle of the PSC motor auxiliary or main winding, respectively, at a sample rate of two-times the line frequency when the PSC motor is ON; and further monitors the PSC motor braking phenomena by counting the residual current alternations when the PSC motor is cycled OFF following the powered portion of each CW or CCW agitator stroke.  The raw PSC motor phase data is used in microcomputer programs to compute motor start time or load torque dither.  This computed information and the PSC motor braking data, is used by other software programs to automati-cally control various functions of the washing machine such as the fill water level and agitator stroke angle; to control events in an operational sequence such as the duration of the agitation and spin operations; and to provide diagnostic infor-mation such as spin off-balance detection.

Patent CA-2024345-A1 (CA)
IPC: H04B10/00
Filed: 1990-08-30
Abstract: An optical communication system in which transmission of information with a pumping light beam acting as the carrier, in addition to transmission of information with a signal light beam, is made possible is disclosed.  This optical communication system includes an optical fiber amplifier adapted to amplify a signal light beam by having the signal light beam and a pumping light beam propagated through its rare-earth-doped fiber doped with a rare earth element and a modulating circuit for modulating the pumping light beam with a high-frequency modulating signal having a period shorter than the life span of fluorescence resulting from an excited state.  In the case where the signal light beam and the pumping light beam are propagated in the same direction through the rare-earth-doped fiber, the transmission of information with the pumping light beam acting as the carrier can constitute a transmission of supervisory signal for an optical repeater, and in the case where the signal light beam and the pumping light beam are propagated in the directions opposite to each other through the rare-earth-doped fiber, a two-way transmission can be achieved by the transmission of information with the signal light beam and the transmission of information with the pumping light beam.

Abstract: A valve which is comprised of a body having an inlet passage and an outlet passage.  The inlet passage intersects the outlet passage at an angle.   The outlet passage has an annular  shoulder.   A plug  is  disposed within  the  outlet passage at the intersection of the inlet passage with the outlet passage.   The plug has sides with openings  thereby permitting fluids to flow from the inlet passage into  the outlet passage.   The plug is telescopically movable in the outlet  passage  between  a  first  position  and  a  second position. In the first position fluids flow from the inlet passage pass  through the openings into the outlet passage. The openings in the plug becoming increasingly restricted as the plug moves toward the second position.   In the second position the openings in the plug are totally obstructed by the outlet passage.   The sides of the plug have an annular flange extending outwardly.  The flange has a channel opening toward  the  outlet  passage.    A  seal  is  disposed  in  the channel.   When the plug is in the first position the seal means is sheltered from fluid flow within the channel.  When the plug is in the second position the seal in the channel engages the annular shoulder.

Filed: 1991-11-22
Abstract: ABSTRACT A spray gun for use with a source of pressurized liquid provided through a supply hose is disclosed having a body with hose connection means at the rear portion thereof and a pistol grip-style handle extending therefrom.  The body has a longitudinally passageway  extending  from  the  hose  connection  means  to  the longitudinally opposed fluid dispensing end of the body.  Disposed within the passageway is a plunger, slidably movable between opened and closed positions to selectively allow the dispensing of fluid through the exiting end of the body.   The plunger includes a longitudinally bore partially therethrough, the rear portion of the bore being in fluid communication with the hose connections means, and radial bores providing fluid communication between the front end of the longitudinal bore and the internal passageway of the body.  The trigger disposed in the handle is operatively connected to a leaver which, upon depression of the trigger, engages a pusher ring which drives the hose  connection means  and the plunger rearward, thereby moving the plunger from its closed to its open position.   A return spring disposed in the passageway provides resistance and biases the plunger in its closed position.   The trigger includes automatic locking means which must be disengaged prior to depression of the trigger.
