Title: Self-Performing Immunochromatographic Device
Inventor: OSIKOWICZ EUGENE W
IPC: G01N33/543
Filed: 1990-10-03
Abstract: Improved chromatographic strip binding assay devices are provided for determining the presence or amount of an analyte present in a patient sample. Assay label reagents interact with capture reagents immobilized in a testing region on the strip substrate to generate a visually detectable image indicative of the test result. The test result images include a minus sign (-) to indicate a negative test result for analyte which image is generated if the suspect analyte is absent in the patient sample and a plus sign (+) to indicate a positive test result for analyte which image is generated if the suspect analyte is present or is present at a pre-determined concentration in the patient sample. The immobilized capture reagents responsible for the location and configuration of the test result images are applied to the strip at an angled orientation with respect to the fluid flow direction of the strip to ensure that sharp substantially complete test result images are formed during performance of the assay. The devices provide substantially self-performing assays having inherently clear test results which are not subject to misinterpretation by the skilled or untrained user.

Title: Engine flow restriction control
Inventor: HUDSON GREGORY L
IPC: F02D9/04
Filed: 1990-07-16
Abstract: The design and construction of present engines (12) have generally not compensated for white smoke during start up and cold operating conditions where incomplete combustion occurs. The present invention overcomes these problems by using a control system (10) adapted to be used with the engine (12) and positioned between a restrictor valve (80) and a throttle (52). The restrictor valve (80) restricts the flow of one of the intake air (30) and the exhaust (32). A mechanical linkage (110) is connected between the throttle (52) and the valve (80). The linkage (110) moves a shaft (90) and a plate (96) relative to the throttle (52) high idle position (100) and low idle position (99) respectively. A first lever (114) has a slot (156) therein and is rotatably attached to the shaft (90) and a second lever (140) is fixedly attached to the shaft (90) and has a pin (152) being generally positioned in the center of the slot (156). The slot (156) allows the first lever (114) to move slightly in either direction relative to the position of the second lever (140) without varying the position of the plate (96) between the generally closed position (100) and the opened position (99).

Title: Differential pressure control system for variable camshaft timing system
Inventor: BUTTERFIELD ROGER P
IPC: F16D3/10
Filed: 1992-05-20
Abstract: A camshaft (126) has a vane (160) secured to an end thereof for non-oscillating rotation therewith. The camshaft also carries a sprocket (132) which can rotate with the camshaft but which is oscillatable with the camshaft. The vane has opposed lobes (160a, 160b) which are received in opposed recesses (132a, 132b), respectively, of the sprocket. The recesses/have greater circumferential extent than the lobes to permit the vane and sprocket to oscillate with respect to one another, and thereby permit the camshaft to change in phase relative to a crankshaft whose phase relative to the sprocket is fixed by virtue of a chain drive extending therebetween. The camshaft tends to change in reaction to pulses which it experiences during its normal operation, and it is permitted to change only in a given direction, either to advance or retard, by selectively blocking or permitting the flow of hydraulic fluid, preferably engine oil, through the return lines (194, 196) from the recesses by controlling the position of a spool (200) within a valve body (198) of a control valve in response to a signal indicative of an engine operating condition from an engine control unit (208). The spool is selectively positioned within the valve body by controlling hydraulic loads on its opposed end, one end being subjected to full system pressure from the hydraulic source (230), the other end being subject to the action of an hydraulic pressure multiplier (234) which receives fluid from the hydraulic source by way of pulse width modulated solenoid (206) that acts to controllably reduce hydraulic system pressure in response to a signal from an engine control unit (208).      The spool is centered when the hydraulic loads acting on its opposed ends by the action of springs (202, 204) that also act on the opposed ends of the spool.
