Patent CA-2057083-A1 (CA)
IPC: H04N17/04
Filed: 1991-12-05
Abstract: Abstract of the Disclosure A tuning system of a television receiver includes a digital automatic fine tuning (AFT) unit for generating a digital AFT signal representing the deviation of the frequency of the picture carrier of the IF signal from a nominal frequency. The digital AFT unit includes a counter for counting cycles of picture carrier during repetitive counting intervals which occur during a measurement period having a duration as least as long as the duration of one field of a television signal. The duration and spacing of the counting intervals are selected so that at least one counting interval occurs during the vertical blanking interval in which the picture carrier is not likely to be over-modulated and therefore not likely to result in erroneous low counts. The contents of the counter are evaluated at the end of each counting cycle to determine if a first count corresponding to a nominal frequency or a second count corresponding to the frequency having a positive frequency deviation have been produced. At the end of the measurement interval, the frequency of the picture carrier relative to the nominal frequency is evaluated by determining which one, if any of the first and second counts have been produced. A low frequency is indicated by the absence of both. A frequency within specified limits is indicated by the presence of the first but not the second counts A high frequency is indicated by the presence of both counts. The technique employed does not require that the timing signal be synchronized with the vertical blanking interval for reliable counting.

Title: Voltage controller with reduced filtering losses
Inventor: AUDBERT JEAN
IPC: H05B39/08
Filed: 1992-01-20
Abstract: The dimmer (G) inserted into a conductor for supplying a power load (C) via the mains (NP) conventionally includes a triac (3) in series with a filtering inductor (4) between input (1) and output (2) terminals, and a circuit (11) generating triggering signals for the triac (3). To minimise losses in the inductor (4), which conventionally is permanently in series with the load (C) but only intervenes in the period following the triggering of the triac (3), in order to minimise the amplitude of the transient currents, a second triac (7) triggered by a circuit (14) with a delay greater than the time constant determined by the inductor (4) and a filtering capacitor (5), diverts the load current. A weak auxiliary inductor (8) attenuates the transients due to the triggering of the triac (7).

Abstract: An adjustable rinse additive dispenser is provided for a dishwasher having a washing compartment and a door pivotal between a horizontal open position and a vertical closed position.  The dispenser includes a rinse additive reservoir mounted on the door.  A conduit provides a fill opening for adding rinse additive to the reservoir.  A knob assembly includes a shaft extending into the conduit so as to substantially seal the opposite ends of the conduit, and defines an annular chamber within the conduit.  A trough is provided in the reservoir for holding a fixed quantity of rinse additive.  A passageway provides communication between the trough and the annular chamber, and is normally closed by a plunger assembly.  During the last rinse cycle of the dishwasher, the plunger assembly is moved to an open position so as to allow rinse additive to flow from the trough into the annular chamber.  A leak path is provided in the knob assembly so as to allow a selective amount of rinse additive to flow from the annular chamber into the washing compartment of the dishwasher.  The quantity of additive dispensed from the annular chamber can be varied by turning the knob assembly such that the angular position of the leak path is raised or lowered.

Title: Wind-resistant heating appliance
Inventor: HAMOS ROBERT E
IPC: F24H1/40
Filed: 1992-08-14
Abstract: WIND-RESISTANT HEATING APPLIANCE           ABSTRACT             A wind-resistant heating appliance has a housing with air inlet openings for sustaining combustion generating flue products inside that housing which also has an outlet for flue products.   The heating appliance has a top structure above that outlet and the housing.  A top wall of that top structure  is  penetrated  with  exhaust  openings  for  flue products along opposite edges of that top structure.  The outlet between the housing and the top structure is provided with a transverse outlet channel inside the top structure and has opposite ends open at the exhaust openings adjacent the opposite edges of the top structure.  That transverse outlet channel is solidly enclosed along its top, sides and bottom between  the opposite  ends,  except  for the outlet between the housing and the top structure.  The exhaustion of flue products in various wind conditions is further aided by increasing the speed of flue products passing through the outlet from the housing to the transverse outlet channel. Where  such  speed  increase is effected by a flue product collector diminishing in cross-section from the housing to the   transverse    outlet    channel,    that   diminishing cross-section  for  exhausting  flue  products  conversely presents an increasing cross-section for downdrafts, which diminishes their impact on the heater operation.

Title: High doppler rate high altitude capability coherent pulsed doppler radar altimeter
Inventor: HAGER JAMES R
IPC: G01S13/50
Filed: 1992-06-24
Abstract: A pulse Doppler radar altimeter designed to resolve the ambiguous range problem associated with the use of a pulse repetition interval, which is less than the aircraft altitude, includes a radar transmitter configured to transmit first and second series of pulses where the first series has a pulse repetition interval slightly different from the pulse repetition interval of the second series. At a time when the first series is being transmitted, the receiver electronics including a range gate and a tracker searches for ground returns and positions the range gate in time coincidence with the detected ground return. Control then shifts so that the second series of pulses is transmitted and a determination is made whether overlap of the range gate with the ground return from the second series corresponds to the same altitude as when the first series was involved. If not, it is known that the detected range is ambiguous and the tracker continues repositioning the range gate (altitude) until an unambiguous range determination is made.
