Title: Aspirator tube check valve assembly and method of continuously sensing vehicular interior compartment air temperature
Inventor: TERRY JOSEPH L
IPC: B60H1/00
Filed: 1992-12-16
Abstract: Abstract Of The Disclosure An interior air temperature sensing system is provided for use with a vehicle interior compartment air temperature regulating system including an ambient air inlet duct, a blower housing connected to an air inlet duct and an air temperature modifier and a blower situated within the blower housing.  The blower draws air from the air inlet duct under negative pressure and conveys the air at positive pressure past the air temperature modifier to the interior compartment.  The air temperature sensing system includes an air temperature sensor and a venturi valve coupled to the negative pressure area of the blower.  The valve includes an inlet port, and outlet port and a venturi section extending therebetween defining a point of minimum flow area, or valve seat.  The valve also includes a diverter channel having a first port in communication with the inlet port and a second port in communication with the outlet port and a plug member situated between the inlet port and the outlet port and having a diameter greater than the valve seat.  As the blower draws ambient air from the inlet duct, interior compartment air is drawn by the sensor and through the venturi valve and across the valve seat and out the outlet port.  If the ambient air pressure exceeds the blower output pressure, the plug member is forced onto the valve seat to divert the oncoming air through the diverter channel creating a secondary venturi and continuing to draw air from the sensor, through the diverter channel to discharge elsewhere within the interior compartment.

Title: Electric arc furnace dust as a raw material for brick
Inventor: FRAME SCOTT W
IPC: C04B33/13
Filed: 1993-04-07
Abstract: A process for producing brick involves calcining electric arc furnace dust and subsequently mixing the dust with a brick raw material prior to shaping the material into bricks and firing. The precalcination of the EAF dust greatly increases the bulk density of the dust and provides a brick having a much higher compressive strength when compared to bricks incorporating raw dust which has not been precalcined. Volatilized and recondensed heavy metals produced during the calcination process are collected and refined.      As a result of the separation and collection of the volatilized heavy metals during the calcination process, substantially no heavy metals are volatilized during the brick firing process.

IPC: G01N27/72
Filed: 1994-06-03
Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for deducing physical quantities such as positions, sizes and orientations of bioelectric current sources.  Minute magnetic fields formed by the bioelectric current sources in a region under examination of an examinee are measured with a plurality of magnetic sensors arranged adjacent the region under examination.  A plurality of lattice points are set in the region under examination. Physical quantities of the current sources are derived by solving a relational expression of unknown current sources at the lattice points and field data provided by the magnetic sensors, with a condition added thereto to minimize a norm of a vector having the current source at each of the lattice points.  The lattice points are moved toward a lattice point having a large current value among the current sources computed. Checking is made whether a minimum distance among the lattice points having been moved is below a predeter-mined value.  The current source computing step to the checking step are repeated for the lattice points having been removed, when the minimum distance exceeds the predetermined value, and the current source corre-sponding to a magnetic field occurring when the minimum distance is determined to be below the predetermined value is identified to be a true current source.
