Filed: 1991-03-01
Abstract: ABSTRACT OF THE DISCLOSURE           The invention is a method for quantitatively determining the amount of saturate, olefin and aromatic components in a composition or mixture.  The     method involves contacting a sample of a composition with a stationary phase; separating the saturates, olefins and aromatics loaded on the stationary phase by passing a supercritical fluid mobile phase through the stationary phase to obtain an eluent, wherein the amount of satu-rates, olefins and aromatics in the eluent varies over time and passing the  eluent through  an  ultraviolet absorption  (Uv)  detector for irradiating the eluent with  ultraviolet  light  at  a  wavelength  capable  of producing a uniform ultraviolet absorbance response for the olefins in the sample; measuring the ultraviolet absorbance of the olefins in the eluent; passing the eluent through  a  mass  detector  (FID),  capable  of measuring the mass response to saturates, olefins and aromatics in the eluent and determining the quantita-tive amounts of saturates, olefins and aromatics in the composition from the detectors.

Patent CA-2042069-A1 (CA)
Title: Power transistor device having ultra deep increased concentration region
Inventor: MERRILL PERRY
IPC: H01L21/331
Filed: 1991-05-08
Abstract: A cellular insulated gate bipolar transistor ("IGBT") device employs increased concentration in the active region between spaced bases to a depth greater than the depth of the base regions. The implant dose which is the source of the increased concentration is about 3.5 x 1012 atoms per centimeter squared and is driven for about 10 hours at 1175°C. Lifetime is reduced by an increased radiation dose to reduce switching loss without reducing breakdown volt-aye or increasing forward voltage drop above previous levels.  The increased concentration region permits a reduction in the spacing between bases and provides a region of low localized bipolar gain, increasing the device latch current.  The avalanche energy which the device can successfully absorb while turning off an inductive load is significantly increased.  The very deep increased conduction region is formed before the body and source regions in a novel process for making the new junction pattern.

Title: Object-based irregular-grid volume rendering
Inventor: LUCAS BRUCE D
IPC: G06T15/50
Filed: 1992-02-12
Abstract: Method and apparatus for rendering data for display. The data represents a model space and the method includes the following  steps.  A  first  step  associates  individual points in the model space with individual vertices (V) of an irregular grid cell enclosed by faces.  Each of the points  has  an associated  luminosity  value  and  an associated opacity value. A next step orders the faces of the grid cells. The faces are preferably ordered by depth referenced to  a view plane.  A further  step processes individual faces for determining,  for all viewing rays that project  from pixels  on the view plane  and that intersect the face being processed,  an amount of light arriving at the pixel. The amount of light arriving at the pixel is a function of both the luminosity and the opacity of a grid cell that lies adjacent to the face and through which the viewing ray passes.

Patent CA-2068033-A1 (CA)
Title: Fiberoptic pressure sensor systems
Inventor: WLODARCZYK MAREK T
IPC: G01L11/00
Filed: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE    The invention is related to numerous improvements for fiber optic measuring systems,  and principally those utilizing a deformable diaphragm for sensing pressure.  One aspect of the invention is providing temperature compensation for diaphragm characteristics.   Temperature measurement can be achieved by using a light signal having a wavelength distribution which overlaps the cut-off characteristics of a filter positioned at the fiber sensing end.  Shifting in the cut-off characteristic in  response to temperature modulates the  intensity of the reflected back temperature compensation signal.   In another approach, temperature is measured through its differential effect on light signals having different launching conditions.  With either approach, the temperature measurement is used to calibrate the output of the pressure sensitive diaphragm.  Another feature of the invention is particularly oriented to automotive engine combustion chamber pressure measurement.  Periodic recalibration of the system can be achieved by measuring pressure at a time when the combustion chamber pressure is known to be close to ambient.  For the automotive engine environment, a sensing tip shielding technique is also described using a sintered metal porous plug, which reduces temperature fluctuations experienced at the sensing tip and shields the sensing tip from corrosive materials.   A techniques for compensation of a fiber optic pressure sensor is described which does not directly measure temperature.  In that method, a referencing wavelength is partly reflect and partly transmitted past a filter coating at the sensing end of the optical  filament.   This  invention also describes techniques for multiplexing a number of pressure sensors and pressure sensing tip having an enclosed volume acting on one side of the diaphragm.

Title: Leveling valve for air springs
Inventor: ANDERSON HENRY M JR
IPC: B60G17/052
Filed: 1992-06-04
Abstract: LEVELING VALVE FOR AIR SPRINGS                 ABSTRACT OF THE DISCLOSURE         A leveling valve for controlling the amount of air within an air spring mounted between two spaced members subject to changes in the distance between them, the use of such leveling valve being primarily in maintaining a constant level of a vehicle chassis or frame relative to its axles in response to the loading and unloading of the vehicle.  The valve provides for an elongated body in which an actuating mechanism is mounted at one end and a valve means at the other end with a dampener and a pilot-operated dump means located between the actuating mechanism and the valve means.  An elongated plunger extends from the actuating means to the valve means through the dampener and the pilot-operated dump means.  One end of the plunger is attached to the actuating mechanism which includes a sleeve slidable on the plunger and on each side of which is located coil springs for maintaining the neutral position of the plunger and valve means.  The springs provide a means for permitting over-travel of the actuating mechanism when the plunger reaches its limit of travel and also assists a dump piston in overriding the actuating mechanism.  The dampener provides a time delay in the actuating of the plunger which also provides a means for minimizing fluctuations in the actuation of the valve means caused by a vehicle encountering large bumps in the road.  The dampener has a unique structure in that it is formed of two transparent parts between which is located a piston and a viscous fluid visible through the transparent parts.  The actuating means is unique by providing rotatable eccentric means on each side of the sleeve adapted to actuate the sleeve and a forked actuator arm having two arms connected to each of the rotatable eccentric means to provide for a balanced actuation of the plunger and valve means.
