IPC: G11B9/00
Filed: 1991-02-02
Abstract: An apparatus capable of detecting a displacement of a probe from a track of a recording medium caused by track fluctuations, vibrations at recording/reproducing period.       For example, a probe 1 is maintained to vibrate at frequency f in the direction perpendicular to a data train 4 at an amplitude smaller than the width of the data train 4.  In this case, the amplitude of a reproduced signal of the data train changes with the displacement between the probe 1 and the data train.  The envelope signal i of the reproduced signal is phase detected using as a reference signal the vibration waveform (standard signal) at frequency f o of the probe 1, to obtain a signal proportional to the displacement from the data train.  Using this signal, it becomes possible to feedback control the probe 1 so as to make it trace the data train.

Inventor: DAUGHTERS TIMOTHY E
IPC: H03H7/20
Filed: 1991-02-11
Abstract: An analog voltage-controlled phase shifter is disclosed which is smaller in size and provides a larger phase shift for a smaller change of capacitance ofpresently available voltage controlled phase shifters. These unexpected advantages are obtained by using lumped elements to simulate the normally used ?/4 transmission lines of the hybrid portion of the phase shifter and by eliminating or reducing the value of the capacitors normally present at the varactor nodes of the hybrid. The capacitance fully or partially removed from the varactor nodes of the hybrid can be selectively fully or partially added to the varactors.

The blades have a curvature trailing the direction of rotation in order to receive wind from any direction. The whole system is rotatably mounted on a housing with two oil cups. The oil cups are with outer walls sloping toward the shaft to induce oil movement in the bearings.

Title: Process for increasing the bitumen content of oil sands froth
Inventor: TIPMAN ROBERT N
IPC: C10G1/04
Filed: 1991-11-08
Abstract: A process and an apparatus are described for separation of water and solids from oil sands froth in which heated froth is fed into a gravity settling vessel at a level below a bitumen-water interface established between a bitumen froth layer floating on a quiescent body of water whereby water and solids contained in the froth separate from the froth stream, the oil rises to accumulate in the bitumen froth layer, and the solids fall by gravity to the bottom of the gravity settling vessel.  The apparatus comprises an injector manifold suspended horizontally within the vessel below the bitumen-water interface, said injector manifold having a plurality of equispaced, inwardly facing openings for the inward discharge of oil sands froth into the body of water. The injector ring manifold may also have a plurality of outwardly facing openings for both inward and outward discharge of froth.   A level probe for monitoring the level of the bitumen-water interface preferably is mounted in the vessel in electrical communication with a valve for discharging underflow for control of the level of the bitumen-water interface.

Abstract: ENGINE TORQUE MANAGEMENT FOR CLUTCH-TO-CLUTCH UPSHIFTING OF AN AUTOMATIC SHIFT TRANSMISSION            Abstract of the Disclosure An improved powertrain control which recognizes the occurrence of engine speed flare during low torque upshifting, and effectively converts the shift to a power-off upshift via an override of the normal engine torque management controls.  The engine spark timing is retarded by a predetermined amount during every power-on upshift for the reasons described above.  However, when the occurrence of engine flare is detected, the control increases the spark retard to a maximum value, substantially eliminating the transmission input torque.  As the on-coming element smoothly applies and decelerates the input, the flare condition terminates, and the spark timing is returned to the predetermined amount for completion of the shift.

Abstract: In a mobile telephone device, an adder (17) calculates a sum of (a) an audio signal comprising a talk signal component and a noise component and (b) a generated signal having an out-of audio frequency, as 6 kHz, and a predetermined level and supplies a compressor (21) with the sum as its input signal,  The adder and the compressor give a less variable gain to the audio signal of a lower level range than to that of a higher level range.          Alternatively, the co?pressor alone gives the less-variable gain to the input signal of the lower level range.  A compressed signal is transmitted to a base station as a radio signal and is expanded.          For use in a radio communication system of the type revealed in United States Patent No. 4,025,853, the generated signal can be    given   either by the supervisory audible tone or by the reference tone.
