Title: X-ray compton scatter density measurement at a point within an object
Inventor: HUSSEIN ESAM M A
IPC: G01B15/02
Filed: 2001-08-22
Abstract: The present invention pertains to a non-rotating method for non-intrusively determining the density of a point embedded within an object, without necessarily obtaining a full image for the entire object. The method consists of passing a X-ray beam through a point within an object and measuring Compton scatterings from the point from a first and second energy bands within the energy spectrum of the X-ray beam, along a first and second angles from the X-ray beam. Using the kinetics of Compton scattering at a specific angle, four equations are formulated with four measurements and four unknowns; the radiation attenuation factor along the object between the X-ray source and the point, the radiation attenuation factor between the point and each of the detectors and the density of the object at the point. The four equations are solved simultaneously to determined the four unknowns. There is also provided a matrix inversion process to facilitate the solution of the equations.

Title: Synchronization system for motors
Inventor: STRONCZEK STEVEN J
IPC: B60S1/08
Filed: 1999-12-29
Abstract: A synchronization system according to the present invention includes a signal generator that provides a "RUN" signal of a predetermined duration simultaneously to two or more windshield wiper motors in response to receipt of position signals generated by the motors. Each motor generates a position signal when the windshield wiper controlled by the motor is at a predetermined position. A  gate circuit monitors the output of each motor to determine whether the motor is in the predetermined position. The gate circuit provides a trigger signal to the signal generator of the present invention only when each motor outputs a position signal. The trigger signal causes the signal generator to produce a subsequent "RUN" signal initiating another wipe cycle. Accordingly, the motors begin each cycle in unison.

Title: Pickup truck bed extender apparatus
Inventor: AFTANAS JEFFREY M
IPC: B62D25/24
Filed: 2001-10-29
Abstract: A bed extender apparatus adapted for use with a pickup truck bed to functionally enlarge the useable cargo area within the truck bed when a tailgate is in a lowered position. The bed extender includes a center wall which is pivotably mounted to an inner surface of the tailgate, and which can be pivoted into an upright position once the tailgate is moved into a lowered position. A pair of end walls are pivotably secured to opposite ends of the center wall. Each end wall can be pivoted out to a position extending perpendicular to the center wall once the center wall is in its raised or operative position. Each of the end walls can then be secured to an associated one of the vertical walls of the pickup truck bed. A principal advantage of the bed extender is that the end walls and center wall each include a plurality of members which, when the end walls are folded against the center wall, form an extremely compact arrangement which takes up virtually no appreciable cargo space within the pickup truck bed. The bed extender also forms an extremely aerodynamically efficient structure when in use.

Title: Carpet extractor with dual nozzles for dual brushrolls
Inventor: LATIMER BRETT A
IPC: A47L11/34
Filed: 2002-01-11
Abstract: A carpet extractor includes a base assembly including a housing which selectively receives a recovery tank for collecting dirty cleaning fluid. A nozzle assembly is mounted to the base housing and provides a fluid flowpath for dirty cleaning fluid from the floor surface to the recovery tank. The nozzle assembly is pivotable from a first position, in which the fluid flowpath communicates with the recovery tank, to a second position, in which the nozzle assembly is spaced from the recovery tank to allow the recovery tank to be removed from the base housing. A second flowpath is formed on the recovery tank between the tank and a nozzle plate. The flowpaths have openings, respectively, at their lower ends, which are located either side of two longitudinally spaced brushrolls. A flap valve selectively closes both flowpaths during above floor cleaning.

Patent CA-2378800-A1 (CA)
Inventor: KOLB ROBERT
IPC: B04C7/00
Filed: 2002-03-25
Abstract: Horizontal, negative pressure centrifugal separator apparatus (48, 248, 348, 448, 548) is provided for separating particulate material from an air stream that exhausts from the outlet of a horizontal, industrial size, rotary drum dryer (32). The centrifugal separator is especially adapted to be connected to the negative pressure inlet of a primary fan (42) which pulls large volumes of air through the rotary drum dryer. The separator apparatus includes wall structure which defines two aligned primary spiral separation plenum chambers (e.g. 78, 80) joined to an intermediate spiral discharge plenum chamber (e.g. 82), all of which intercommunicate. A pair of oppositely facing plenum chamber divider members each having a central aperture therein are mounted in the plenum chambers on opposite sides of the discharge plenum chamber and function as pressure regain stacks. Air streams containing particulate materials which are introduced into the air inlets of the primary separation plenum chambers each follow a serpentine path in a respective primary chamber before flowing through a corresponding plenum chamber divider member spiral velocity regain stack into the spiral chamber of the discharge plenum chamber. Discharge openings are provided in the primary spiral plenum chambers in positions permitting particulate material separated from the air stream as a result of centrifugal force thereon, to gravitate to a collection point therebelow. The centrifugal separator apparatus will handle an approximately 40% greater air flow than a comparable, conventional cylindrical stack member with essentially the same pressure drop.

Patent CA-2381867-A1 (CA)
Inventor: AKASHE AHMAD
IPC: C11B5/00
Filed: 2002-04-16
Abstract: The present invention generally relates to inhibition of oxidation of polyunsaturated lipids by mixing the polyunsaturated lipids with a combination of polyamines providing a unique anti-oxidative effect on the polyunsaturated lipids. A especially advantageous combination of polyamines used in this regard includes spermine and a different linear aliphatic polyamine, such as spermidine, putrescine, or mixtures thereof. The rate of off-flavor development is significantly reduced in polyunsaturated lipids blended with such combinations of different polyamines. In addition, polyunsaturated lipid-containing materials and compositions can be stabilized using edible, non-toxic anti-oxidants based on such polyamine combinations. Omega-3 fatty acids and compositions containing them are especially well-suited for processing in this manner. The stabilized polyunsaturated lipid-containing products obtained in this manner have extended shelf-life while permitting the health and nutritional value of the treated lipids to be more fully accessed.
