Title: Arrangement for transferring castable material without pipes from a feeding means to a destination
Inventor: SPIES KLAUS
IPC: B65G31/04
Filed: 1991-04-26
Abstract: ABSTRACT OF THE DISCLOSURE      An arrangement for transferring castable material without pipes or conduits from a feeding point to a destination, particularly in underground mining.  The arrangement includes a driven centrifugal wheel with blades.          The centrifugal wheel is radially open and is surrounded in the manner of a jacket by an endless housing belt which is guided on guide rollers.  The portion of the centrifugal wheel which is radially open is bordered by the guide roller which causes the housing belt to contact the centrifugal wheel and by the guide roller which raises the housing belt from the centrifugal wheel.  The material is radially discharged in a concentrated manner through this radially open portion.  The material is supplied axially to the centrifugal wheel through a feed tube and enters through a discharge opening of the feed tube on the vertical level of the blades into the centrifugal wheel.

Title: Method and appartus for controlling air-fuel ratio of gas engine
Inventor: YAKABE HISATAKA
IPC: G05D11/02
Filed: 1991-09-05
Abstract: A method and apparatus for controlling and improving the air-fuel ratio of a gas engine by controlling the air-fuel ratio on an exhaust purifying apparatus such as a three way catalyst in use with the gas engine.  The method involves the steps of modulating a vibrational drive current for driving a bypass value with waveforms such as rectangular wave, sinusoidal wave, triangular wave, etc., with predetermined periods and amplitudes, in response to signals transmitted from a main oxygen sensor and a pressure sensor.  The main oxygen sensor being installed on an up-stream side relative to the three way catalyst interposed on an exhaust line of the gas engine, and the pressure sensor being installed on an intake line in communication with a mixer; detecting distortion of responded waveforms of signals transmitted from a sub oxygen sensor, which sensor is installed on a down-stream side of the three way catalyst; and controlling the drive current so as to remove the detected distortions, in order to help optimize the air-fuel ratio of the gas engine.          The invention thus helps in optimizing control of the air-fuel ratio and helps in the purification efficiency of the gas engine exhaust.

Patent CA-2077246-A1 (CA)
Inventor: CUFFE JOHN M
IPC: G01N29/22
Filed: 1992-08-31
Abstract: Test apparatus (10) performs non-destructive testing of an object (O) to determine if it has flaws or defects.  An ultrasonic wave (W) is generated and directed at the object.  A return wave (R) reflected by the object is received and analyzed to determine if a flaw or defect.  The return wave is converted to digital data which is stored for purposes of later analysis.  For this purpose, digital signals containing the data are routed over a quiet bus (24).  Digital signals are routed over the bus prior to generation of an ultrasonic wave to establish test parameters.  Digital noise may occur during the transmission.  A controller (22) controls routing of digital signals over the bus.  The controller inhibits the flow of digital signals over the bus during that portion of an operational cycle of the apparatus during which the ultrasonic waves are produced and return waves evaluated.  The controller allows transmission of digital signals over the bus at other times.  As a result, the ultrasonic portion of the apparatus is effectively isolated from the bus so any digital noise thereon cannot effect the ultrasonic portion of the apparatus and the test results produced thereby.
