Inventor: GREENQUIST ALFRED C
IPC: G01N33/53
Filed: 1986-08-12
Abstract: A multizone test device for the determination of analyte from a liquid test medium upon contact with the liquid test medium and a labeled reagent comprising a chemical group having a detectable chemical property. The test device preferably comprises multilayers including a reagent layer incorporated with an immobilized reagent and a detection layer incorporated with an immobilized form of an interactive detection reagent for the labeled reagent. The immobilized reagent in the reagent layer and the labeled reagent comprise specific binding partners which will bind to each other dependent upon the amount of analyte present. Labeled reagent which does not become bound to the immobilized reagent in the reagent layer migrates into the detection layer and interacts with the immobilized interactive detection reagent therein which results in the localized generation of a detectable reaction product which preferably is also immobilized in the detection zone. As a result, reverse migration of the labeled reagent, and preferably the detectable reaction product from the detection layer is prevented and the detectable chemical property provided by the label of the labeled reagent is localized in the detection layer for the precise measurement thereof and correlation to the amount of analyte in the test medium.

Abstract: 1,162,067. Fluid-pressure servomotor systems. ATLAS COPCO A. B. June 8, 1967 [June 23, 1966], No. 26481/67. Heading G3P. A two-stage screw-action compressor 2, 3 has a throttle valve 6 in the intake duct 4 and an unloading valve 22 in a vent line 17 connected to the delivery line 12. Valves 6, 22 are biased by spring 33 to the positions shown. On starting the compressor, a vacuum is created in duct 5 and acts, via restricted line 30, line 31 and pilot valve chambers 34, 36, in chambers 28, 29 of rolling diaphragm motor 26. To load the compressor, a spool 66 is depressed to admit oil under pressure to line 46 to lift diaphragm 48 to reposition valve 37, to seat head 38 and unseat head 39. The vacuum in line 8 has moved flap 54 to the position shown and inlet pressure in duct 4 now acts via chamber 53 and lines 51, 70 in chamber 29 to move the valve 6 to an open position and the valve 22 to a closed position. Oil pressure in line 68 maintains the spool 66 in its depressed position. Flap 54 is now moved by the interstage pressure in line 8 to seat at 57 and admit this pressure to chamber 29 to maintain valve 6 open and valve 22 closed. When the pressure in receiver 14 reaches the desired level, valve 72 admits this pressure to chamber 74 to return valve 37 to the position shown. The pressure across diaphragm 26 is thereby equalized and the valves 6, 22 are returned to the unloading positions shown. Line 58 may alternately connect with the outlet duct 12. In the modification Fig. 2 (not shown), valve 60 is replaced by a solenoid operated valve (76) the coil of which is in circuit with a pressure switch (77) replacing valve 72. The compressor motor contactors (81) are in parallel with a time delay relay operating a switch in the coil circuit. In Fig.3 (not shown), the valves (37, 76) of (Fig. 2) are replaced by a solenoid operated valve (176) serving to connect chamber 29 alternately to chamber 28 and to the output of valve 52. The coil of valve (176) is in a circuit identical to that of (Fig. 2). The compressors may be screw-type and, if a single stage compressor is used, line 56 communicates with the output duct.

Title: Apparatus and method for locally heating conveyed glass sheets
Inventor: NITSCHKE JOHN STEPHEN
IPC: C03B23/025
Filed: 1983-08-17
Abstract: An improved apparatus including a localized heater that moves along the direction of conveyance with conveyed glass sheets to provide localized heating of a portion of each glass sheet to be bent without heating the rest of the glass sheet prior to its subsequent treatment. This invention is especially suitable for locally heating designated portions of glass sheets as they are heated while being conveyed through a furnace on a horizontal roller conveyor where the designated portion of glass sheets are to be formed with bends having relatively short radii of curvature at a bending station. The apparatus includes a pair of elongated localized gas heaters, each of which is positioned above the portion of the glass sheet which requires significant bending. These heaters are mounted on a carriage driven by a drive mechanism. The drive mechanism causes the carriage to move along a path parallel to the path of glass sheet conveyance to allow the heaters to continuously heat the designated portions of the glass sheet between an upstream position and a downstream position of the carriage. After the carriage reaches its downstream position, the drive mechanism causes the carriage to return to its upstream position in preparation for another cycle.

Title: Centrifugal separator and method of operating same
Inventor: BOCCKINO HARRY GEORGE
IPC: B04B5/12
Filed: 1984-04-12
Abstract: A continuous flow device is disclosed for separation of particles of differing densities in a centrifugal force field. Very small particles of differing densities that are normally very difficult or impossible to separate in the usual commercial gravity separation devices can be separated because of the increased settling force due to the centrifugal force field and also the buoyant force on the particles of lesser density caused by a thickened slurry layer. A thin film of a slurry of solid particles of differing size and density travels over a revolving surface (20) of such configuration that the slurry flows in a substantially laminar manner. As the thin film of slurry flows along the surface, the particles of greater density tend to concentrate in the region next to the surface (20), while the particles of lesser density remain in or are forced into the fraction of the film closestto the axis of revolution (14). Before the film of slurry reachs the end (24) of the flow path it is passed over a splitting device (21) to separate the fraction of the film containing particles of greater density from the fraction containing particles of lesser density.
