IPC: G01N33/543
Filed: 1989-01-25
Abstract: This invention presents novel separation and assay procedures which allows both the indicator and the capture reagents to be in solution to avoid problems of slowed immunoreaction kinetics. The separation procedure involves an analyte-specific soluble capture reagent, that is conjugated to a charged substance, and an insoluble solid phase material that is oppositely charged. A fluid sample suspected of containing the analyte is mixed with the capture reagent in solution to form a charged capture reagent/analyte complex. When binding is complete, the solution is contacted to the oppositely charged solid phase material to attract, attach, and separate the capture reagent/analyte complex from the fluid sample. With the appropriate indicator reagent, i.e., a second analyte-­specific binding substance which is conjugated to a label capable of producing a detectable signal, both sandwich and competitive assays can be performed. The assay reaction complex can be separated from the solution by contact with the oppositely charged solid phase material, and the presence or amount of analyte is monitored by detecting the label of the indicator reagent.

Abstract: This disclosure relates to a method and reagents for determining amphetamine and d-methamphetamine in a biological fluid, such as urine. In particular, this disclosure relates to improvements in a fluorescence polarization immunoassay procedure for determining the presence of amphetamine and d-methamphetamine in a single assay and to a novel class of tracer compounds employed as reagents in such procedures. The procedure described includes pretreatment of the biological sample to eliminate cross-reactants such as β-hydroxyphenethylamine by preincubating the sample solely with an aqueous periodate solution having a pH from about 4.0 to about 7.5 without adjustment to an alkaline pH, and contacting the sample with riboflavin binding protein to reduce interference from fluorescent components in the sample. The procedure also maintains the cross reactivity of the immunoassay for tyramine at about 0.4% and for l-methamphetamine below about 5.1% and eliminates the necessity of using controlled substances as starting materials.

Abstract: Halftone dots are formed on the basis of three sets of screen pattern data assinged to a same combined area, in which a plurality of halftone dots are to be formed. The three sets of screen pattern data have different threshold values assinged to respective pixels in the combined area, and are stored in SPM's (101-116): eight SPM's store a first set of the screen pattern data, six SPM's store a second one, and two SPM's store a third one. One of the sixteen SPM's is randomly seleoted with respeot to each pixel, whereby one of the threshold values (D s ) stored in the selected SPM is compared with an image singal (V₁). A dot signal indicating whether or not each pixel is solid is produced on the basis of the comparison. Accordingly, a grid-like pattern of halftone dots to be seen in a highlight area or a shadow area is prevented.

Abstract: Water absorbent particulate polymers and their uses are described. Friable aggregates may be made by bonding substantially dry polymer particles with an aqueous liquid and drying the aggregates. These aggregates can be broken down to the individual polymer particles upon mixing with an aqueous medium and thus can have the flow properties of relatively coarse particles and the performance properties of relatively fine particles. They may be soluble and used as flocculants or viscosifiers or binders for, for instance, iron ore pelletisation. Alternatively they may be swellable and insoluble, for instance for converting a sticky particulate mass (such as coal fines filter cake) to a crumbly solid. When pellets are formed by compression moulding from a crumbly solid made by mixing water absorbent polymer particles with a sticky mass of inorganic particles (such as a coal fines filter cake) improved properties are obtained when the absorbent polymer particles are introduced in the form of a dispersion in water-immiscible liquid.

Abstract: To produce a highly resolved photoresist structure, a simplified multilayer photoresist system is proposed in which an internal mask for a second flood exposure is produced in a photoresist layer by means of a first structuring exposure at low light intensity followed by a chemical treatment. In the regions exposed first, opacity for the second exposure is achieved by treatment with a UV light absorber, while treatment with a multifunctional component produces a crosslinking of the basic polymer which renders these regions insoluble with respect to the developer used in the final development step. The process, which is in total simple to carry out, makes it possible to produce highly resolved photoresist structures with vertical edges and high aspect ratio. <IMAGE>

Abstract: A fast acting valve actuator for actuating an intake or exhaust valve in an internal combustion engine of a type which is hydraulically powered and command triggered is disclosed and includes a cylinder with a power piston having a pair of opposed working surfaces or faces reciprocable within the cylinder along an axis between first and second extreme positions. A cylindrical control valve is located radially intermediate the reservoir and the cylinder, and is movable upon command to alternately supply high pressure fluid from a reservoir of high pressure hydraulic fluid to one face and then the other face of the power piston causing the piston to move from one extreme position to the other extreme position. The cylindrical control valve may be a shuttle valve which is reciprocable along the axis of the power piston between extreme positions with control valve motion along the axis in one direction being effective to supply high pressure fluid to move the piston in the opposite direction. Both the control valve and the piston are stable in both of their respective extreme positions and the control valve is spring biased toward a position intermediate the extreme positions. The latter portion of piston motion during one operation of the valve actuator is effective to cock this spring and bias the control valve preparatory to the next operation.
