Patent CA-2068186-A1 (CA)
Title: Load current commutation circuit
Inventor: HOWELL EDWARD K
IPC: H03K17/08
Filed: 1992-05-07
Abstract: Arrangement for arcless interruption of a-c load current in response to a current interruption command. Separable contact means serially connected with controlled impedance means, and parallel connected diversion means are intermediate the a-c source and the load. The controlled impedance comprises field effect transistors (FETs). Since FETs usually have only a single inherent function, at least a pair of the Fets are oppositely poled so that load current can be cut off notwithstanding the direction of current flow when interruption is commanded. The pair of FETs may be connected back to back.        An alternative embodiment has two branch circuits each comprising a FET and a separable contact means. Upon interruption load current is sequentially transferred from one to the other branch circuit and then to the diversion means.

Patent CA-2076905-A1 (CA)
Title: Processor for photosensitive material
Inventor: MULLER BRUCE R
IPC: G03D13/00
Filed: 1992-08-26
Abstract: PROCESSOR FOR PHOTOSENSITIVE MATERIAL             ABSTRACT A pump circulates water from a wash-water chamber to a diverter valve where it can be directed wither to a heat exchanger in a processing fluid chamber or directly back to the water chamber.  The temperature of the processing fluid is detected by a sensor, and a microprocessor controls the diverter valve as a function of the temperature detected by the sensor in order to maintain the temperature of the processing fluid at a desired set point.  The water temperature increases over a period of time, and may reach a level where the desired set point temperature cannot be maintained.  If this occurs, the microprocessor opens a valve to a building water supply to add fresh, cool water to the water chamber.

Patent CA-2084973-A1 (CA)
Inventor: UEMATSU MASAHIRO
IPC: G01S3/38
Filed: 1992-12-09
Abstract: A receiving antenna apparatus for broadcast by satellite for mount on a mobile body in which radio wave interruption tends to occur by obstacles attains high-speed automatic tracking function capable of catching the satellite again in a short time just after cutting off of radio waves.  In the receiving antenna apparatus, an incoming direction of radio waves is roughly detected to limit a search area and then a gain of tuners is then reduced to a value in the tracking control capable of detecting a peak and confirming a main lobe in accordance with power level of the received signal, 80 that a narrow and fine search may be made only in the limited search area.  The antenna apparatus includes a gain setting device for varying gains of AGC of tuners.  Upon search of the satellite, gains of the tuners are set to a first gain by the gain setting device to perform the rough search and the gains of the tuners are reduced to a second gain lower than the first gain to perform the fine search.  Thus, a time required to catch the satellite again after cutting off of radio waves can be made reduced.

Title: Down-the-hole drill
Inventor: EKWALL BERNDT
IPC: E21B4/14
Filed: 1992-12-15
Abstract: Down-the-hole drill comprising a housing (1), a hammer piston (6) movable to-and-fro in the housing and intended for impacting a drill bit (5).

Abstract: In a radio communication apparatus which uses a common carrier frequency on transmission and reception operations selectively carried out in the apparatus, a frequency divider is located between a modulator operated by a predetermined modulation frequency and a modulating local oscillator which oscillates a modulating frequency equal to an integral multiple N of the predetermined modulation frequency.  The frequency divider has a frequency division factor equal to N and supplies a frequency divided signal of the predetermined modulation frequency to the modulator during the transmission operation under control of a control circuit.  During the reception operation, the frequency divider is put into an inactive state by the control circuit to isolate the modulating local oscillator and the modulator.
