Filed: 1989-11-27
Granted: 1994-05-03
Abstract: Abstract of the Disclosure A CPFSK quadrature modulator (300) is disclosed utilizing an all-digital implementation. The serial data input signal (201) is formatted into parallel overlapping bits using a shift register (202), an up/down counter (206), and an interpolation counter (204), and applied as address lines to in-phase and quadrature-phase memories (208, 210). A multiple of the bit clock is used to address carrier generation ROMs (216, 218). The carrier signal is then modulated by the in-phase and quadrature-phase data signals (212, 214, 222), converted to an analog signal by a D/A converter (250), and low pass filtered (254) to generate the analog output signal (255). A single ROM (440) is utilized to implement all the look-up tables, multipliers, and adder. The all-digital implementation allows for precise control of the modulation index to h=0.5 ? 0.05 percent over time, temperature, power levels, etc.
Patent CA-2005620-C (CA)
Title: High intensity radiation apparatus and fluid recirculating system therefor
Inventor: CAMM DAVID M
IPC: H01J61/52
Filed: 1989-12-15
Granted: 1995-05-09
Abstract: An apparatus for producing high intensity radiation has electrodes positioned within an elongated cylindrical arc chamber across which an arc discharge can be established. Liquid is injected into the arc chamber to produce a vortex motion therein to form a cylindrical liquid wall adjacent to the chamber, which constricts the arc by cooling an outer periphery thereof. Gas is injected into the arc chamber to produce a vortex motion adjacent the cylindrical liquid wall. An exhaust structure actively exhausts the liquid and gas from the arc chamber to reduce turbulence and restriction of fluid.  This permits attainment of higher flux densities in the arc, and/or extension of electrode life. Preferably, the liquid and gas are exhausted actively by means of an ejector pump which ejects pressurized liquid into the gas and liquid leaving the arc chamber.  The ejector pump pressurizes the exhausted gas and liquid sufficiently to permit the gas to be separated and recycled back to the arc chamber, without requiring an additional compressor to increase gas pressure.

Abstract: An exerciser is provided for application of an anatomically applied force to the jaw for pivoting of the jaw at its tempero-mandibular joint or to provide a motion to the jaw, or resistance to motion of the jaw which is beneficial in facial orthopedics. A structure is provided having curvilinear guide tracks which guide movement of a carriage according to the character of movement that is desired. The carriage is movable to thereby allow corresponding movement of a mandibular jaw member supported by the carriage relative to a maxillary jaw member supported by the exerciser body. Through suitable linkages, motion may be imparted to the carriage or resistance exerted against its motion by manual action, resilient means or a motor. The linkage may provide for adjustment of mechanical advantage or range of motion through selection of slots or holes formed in parts of the linkage structure.

Title: Method for improving sustained solids-free production from heavy oil reservoirs
Inventor: SMITH ROGER C
IPC: E21B43/267
Filed: 1990-11-13
Granted: 1997-12-16
Abstract: A method for controlling formation fines when producing viscous oil from a consolidated or loosely consolidated formation having at least two wells therein.  Both wells are perforated and the formation is hydraulically fractured at a lower level via a viscous gel fluid having a size and temperature resistant proppant therein. The proppant is of a size sufficient to filter formation fines from the oil. Cyclic steam-flooding and oil production are continued in one well, while the other well, is shut-in. Prior to steam break through, the lower perforated intervals are isolated with production packers containing knock-out plugs.  A correlatable selected upper interval in both wells is perforated and hydraulic fracturing is repeated.  Cyclic steam-flooding and oil production are continued in the upper interval until steam break through occurs.  Cyclic steam-flooding is ceased and production strings are directed through the knock-out plugs into the lower interval.          Thereafter, steam is directed down the annulus from a first well into a second well in the upper interval, while producing oil from the lower interval.  Thereafter, steam is circulated down both wells into the upper formation causing the formation of a "heat chest" and the production of hydrocarbonaceous fluids from the lower interval via the production string.

Title: Internal combustion engine and method
Inventor: HARING JOHN MCMASTER
IPC: F02B29/04
Filed: 1991-06-21
Granted: 1996-10-22
Abstract: Disclosed are methods of and means  for an improved internal combustion engine performance and of substantially reduced or eliminated pollutants.   A relatively slow and long burning combustion is provided which produces an exhaust of high pressure which can be utilized to drive a turbocharger or cylinder or subsequent cylinders.  Ideally, the compression ratio is reduced with respect to current  internal combustion engines,  and the maximum temperature in the power or combustion cylinder can be below the temperature at which NOx is formed.   Preferably the pressure during combustion remains substantially constant and the air or air/fuel mixture is externally compressed 40 to 100% of its compression pressure in the combustion cylinder.  This results in a controlled energy release tailored to a change in volume per unit of time which results in more torque and horsepower,  less fuel consumption and drastically decreases pollution, both chemical and heat to the atmosphere.   A number of preferred embodiments are disclosed.

Title: Handheld screw driving gun
Inventor: FARIAN GERHARD
IPC: B25B23/06
Filed: 1991-07-26
Granted: 1995-04-04
Abstract: A handheld screw driving gun has a handle extending essentially perpendicularly relative to the motor axis and a screwing axis which is off-set below the motor axis. The handle is connected approximately at the center of gravity of the screw gun.  A screwing bit is also offset from the motor axis and is rotatably supported in a guide head between the motor axis and the handle.  In this arrangement, the index finger of an operator's hand on the handle approxi-mately aligns with the axis of the screwing bit so as to assure a screwing direction perpendicularly to a work sur-face without applying any tilting forces to a screw.  The arrangement of the drive motor behind the handle and the screwing unit in front of the handle provides a balance that reduces fatigue while holding and operating the screw gun with one hand.

Title: Air ring and method for controlling blown film thickness
Inventor: SMITH DAVID J
IPC: B29C48/92
Filed: 1992-02-26
Granted: 2002-02-05
Abstract: Apparatus and method are described for controlling thickness of plastic films produced by the blown film process. The apparatus is an air cooling ring modified to include devices for locally modifying the temperature of the air discharged from the air ring onto the blown bubble. Local variations in the temperature of the cooling air applied to the surface of the bubble result in variations in the bubble cooling rate and viscosity, with consequent variations in thinning during transverse bubble expansion. The method comprises centrally the location and extent of local temperature variation applied to the bubble in response to comparison of measured film thickness with a desired film thickness.

Title: Transponder system
Inventor: HOOK CHRISTOPHER
IPC: G06K19/07
Filed: 1991-05-01
Granted: 1999-07-27
Abstract: An electronic identification system comprising a transmitter (5) for generating an electromagnetic excitation signal, one or more portable transponder (3) for storing variable identification data, and for transmitting an information signal containing the identification data upon entering the field. Transmission of the information sig nal is independent of the excitation signal in both time and frequency. A radio frequency receiver is provided for receiving the inf ormation signal and in response generating an output signal representing the variable identification data contained in the in formation signal. THe system overcomes two principle disadvantages associated with existing systems: an excitation frequenc y can be selected for optimum performance given circumstances dictated by each application; an independent response channel can be selected according to the requirements of each installation or application, thereby allowing response signals to be transmitted by transponders at a frequency which differs from the frequency of an interfering signal.
