Patent CA-2066420-A1 (CA)
Inventor: RICH RANDALL W
IPC: H04W92/00
Filed: 1991-07-11
Abstract: A frequency control system (126) for locking the frequency of a receiver, susch as a receiver portion of a transceiver, to the frequency of a transmitter, such as a base station. The frequency control system (126) is operable to determine a center, or other reference, frequency of a signal, either a conventional analog signal, or discrete, encoded signal. The frequency control system may be advantageously embodied in a dual-mode radiotelephone operable to receive both conventional, analog signals and dis-crete, encoded signals.

Title: Disk file with liquid film head-disk interface
Inventor: ALBRECHT THOMAS R
IPC: G11B25/04
Filed: 1992-04-29
Abstract: DISK FILE WITH LIQUID FILM HEAD-DISK INTERFACE                  ABSTRACT    A disk file with substantially reduced head-disk spacing and corresponding improvement in recording performance uses a disk coated with a film of conventional high viscosity lubricant, a lubricant reservoir for replenishing the lubricant on the disk over the life of the file, and a transducer carrier with feet which ski on the high viscosity liquid film.  The file does not include any means for recirculating the lubricant since the lubricant spins off the disk at a relatively low rate due to its high viscosity.  The lubricant reservoir contains a very small amount of lubricant and thus may be maintained inside the substantially sealed disk file.  In one embodiment of the invention, the sealed disk file is essentially evacuated.  The operation of the disk file in a near vacuum environment is possible because, unlike conventional disk files, air is not required to support an air-bearing head-disk interface and the high vapor pressure of the relatively high molecular weight lubricant prevents its evaporation.

Abstract: An apparatus for lowering a cremation urn into a burial hole comprises a substantially rectangular frame formed by connected rails to leave an opening at the center of the frame to span the hole into which the urn it to be buried.  A square  platform  is  positioned  within  the  opening  with  a horizontal surface of the platform lying in a common plane with the top horizontal surface of the frame.   The platform can be moved  from  the  raised  initial  position  to a  lower  position within the hole by two pairs of cable each being connected to a respective shaft on a respective side of the platform.   Each cable passes over a guide bar at a top edge of the frame and extends therefrom to a connecting bar joining the two cables on one side of the platform.   A connecting bar is attached to the platform by a hook and eye arrangement which can release when the platform reaches the ground surface at the bottom of the hole  simply  by  tilting  of  the  connecting  bar  about  its longitudinal axis.

Abstract: The    Video   Insertion   Processing   System   (VIPS) architecture provides the system architect with a modular and parallel approach to graphic processing.  Using a core set of graphic modules, a wide range of graphic processing requirements can be satisfied.  By providing the capability to support independent graphic paths, the performance can increase by N times for each set of graphic paths added. The use  of  independent  graphic paths  also  increases  the systems capability to meet real time response requirements. The key to the VIPS architecture is the ability to merge images from multiple frame buffers  into a single display image.  The final image is a result of selecting each pixel source based on the pixel s priority.   This provides the graphics  system  with  the  capability  of  image  overlay, underlay, merge and hide regardless of shape or size.   A parallel pipelined approach provides the VIPS architecture with the capability of merging multiple  images generated from the different graphic paths on a pixel by pixel basis without degradation of overall system performance.

Title: Pulse cathodic protection system
Inventor: DONIGUIAN THADDEUS M
IPC: C23F13/04
Filed: 1992-08-24
Abstract: A circuit and method of cathodically protecting ferrous metal  structures such as pipelines or well casings is described disposed in a conductive medium such as the ground.  A pair of terminals are connected to an  anode  spaced from the  structure and to the structure.   A source of d.c. voltage is periodically connected across the terminal to cause current to flow to the anode and provide electrons at the surface of the structure to inhibit ferrous molecules from going into solution and damaging the integrity of the structure. The current flow due to the induced emf caused by the reactive  inductions  of the anode/cathode  system is limited  to  inhibit  damage  to  neighboring  ferrous structures by providing a high impedance, e.g. an open circuit,  between the input terminals during all or part of the time that the d.c.  source is not  supplying current to the anode/cathode load.

Abstract: A slope controlled modulation Spread Spectrum TDMA System used in tracking the absolute position of moving targets by radio or other electromagnetic or acoustic radiated energy systems having a master clock (M) transmitting time reference to a network of fixed receivers (RX1, RX2...), a mobile transmitter in a vehicle (V) generating a signal (Tx) with a stimulus preceding the prescribed modulation signal. This signal is of incremental and/or decremental time and/or frequency, amplitude, phase or interval modulation domain(s). All the fixed receivers (RX1, RX2...) may be normalized to an absolute reference (M) common to all receivers based on propagation time differences between each receiver and the stationary time reference (M). The known relationship of receiver timing differences are used to calculate time of arrival epochs from any mobile transmitter and then substracting these timing differences from the calculated time of arrival epochs from the transmitters. These are then sent to a region computer (C) to calculate time of arrival differential of epochs relative to each receiver (RX1, RX2...) in order to provide a position fix of the transmitter (V). The transmitter (V) has a facility to produce the stimulus in signal (Tx) as chirp modulation from which the slope controlled modulation is derived and the receivers (RX1, RX2...) having the facility to decode stimulus events.

IPC: B22D11/114
Filed: 1992-03-27
Abstract: A system for removing non-metallic inclusions in molten steel composed of a tundish and a coil device, wherein the tundish is an intermediate vessel that receives molten steel from a ladle, cleans the same by removing non-metallic inclusions therein, and feeds molten steel so cleaned into a mold. In order to remove non-metallic inclusions, the tundish has a circulation tank and a floating tank. A coil device is provided around the circulation tank of the tundish for circulating molten steel in the circulation tank. The tundish and the coil device are separate bodies, and are constructed so as to move relative to each other. Molten steel in the circulation tank of the tundish is circulated in a horizontal direction by virtue of the magnetic field generated by the coil device and is formed to have a parabolic, concaved surface so as to force non-metallic inclusions in the molten steel to float to the parabolic, concaved surface of molten steel for removal with a suitable means. Molten steel so cleaned flows from the circulation tank into the floating tank, where non-metallic inclusions still remaining in so-cleaned molten steel float in a calm current therein. Molten steel cleaned therein is then poured via the bottom portion of the floating tank into a mold. Since the tundish and the coil device are separate bodies, coil devices can be fewer than tundishes, resulting in lower equipment costs, and easier and less-time-consuming operations in replacement and repair of tundishes.

Abstract: A display integrated type position reading apparatus includes a display device driven for display in accordance with a driving signal in synchronization with a predetermined clock signal, and a conductive tablet mounted on a display screen of the display device.  In operation, a CPU controls a tablet controller to apply voltage to the tablet.  In response to a depression of an arbitrary position on the main surface of the tablet, the CPU reads out the depressed position as a digital signal via an A/D converter.  The sampling by the A/D converter relating to the reading is carried out at sampling points so as to avoid the mixing of noise caused by a signal for driving the display unit into the digital signal, resulting in an improvement in the read out accuracy of the depressed position.
