Title: Catalyzed reporter deposition
Inventor: BOBROW MARK N
IPC: C07D207/46
Filed: 1990-03-28
Abstract: The present invention concerns a method to catalyze reporter deposition to improve detection or quantitation of an analyte in a sample by amplifying the detector signal which comprises immobilizing an analyte dependent enzyme activation system which catalyzes deposition of reporter by activating a conjugate consisting of a detectably labeled substrate specific for the enzyme system, said conjugate reacts with the analyte dependent enzyme activation system to form an activated conjugate which deposits substantially wherever receptor for the activated conjugate is immobilized, said receptor not being reactive with the analyte dependent enzyme activation system. In another embodiment the invention concerns an assay for detecting or quantitating the presence or absence of an analyte in a sample using catalyzed reporter deposition to amplify the reporter signal.

Abstract: Circuitry and method for integrating current pulses, the circuitry including an integration amplifier having an integration capacitor located in its feedback loop.  The current pulse integrator also includes three current sources and four current switches.  A first current switch is located between a first current source and a second current source.  A second current switch is located between the output of the integration amplifier and the second current source.  A third current switch has one end connected to the first current source and the input to the integration amplifier, and the other end connected to the third current source.  A fourth current switch is connected between the output of the integration amplifier and the third current source.  Current passes through the integration capacitor in a first direction to charge the integration capacitor during a charge state of operation of the current pulse integrator. Current is prevented from passing through the integration capacitor in the first direction during at least one other state of operation of the current pulse integrator.  An output current from the integration amplifier during the charge state of operation is substantially equal to an output current from the integration amplifier during the other state or states of operation.

Abstract: A no-twist ("NTA") apparatus and method for manufacturing steel reinforcing bar which allows steel reinforcing bar to be manufactured with greater speed and precision than by conventional methods.  The NTA method employs numerous stands, with the shafts of the rolls of the first two stands offset 45° from a predetermined plane and 90° from each other.  The third and fourth stands comprise rolling and splitting stands and the shafts of their rollers are perpendicular or parallel to the predetermined plane and form equal angles with the shafts of the first two stands so that the bar can be fed to the rolling and splitting stands without intermediate twisting and the single bar can be split into a plurality of bar segments.  The remaining stands are arranged into at least two lines of stands, in each of which the sides of the rolls of the first stand are offset 45° in a first direction from the predetermined plane and the sides of the rolls of the second stand are offset 45° in a second direction opposite to said first direction relative to the predetermined plane.  Alternatively, the sides of the rolls of the first and second stands in the two lines are respectively offset either by 90  and 0° or 0° and 90°.

Filed: 1991-03-01
Abstract: A decorative wall covering and method of installation. The wall covering includes a plurality of identically molded panels each having first and second predetermined laterally spaced vertical cutting lines and being formed with horizontal rows of laterally spaced simulated shake. The first panel of each alternate course in the vertical direction is cut along the first cutting line and the first panel of every other course is cut along the second predetermined cutting line, whereby the lowermost row of simulated shake of the panels of each course are automatically offset from the uppermost row of the panels in the course immediately therebelow. The overlapping marginal edge regions each are formed with a plurality of parallel water barrier ridges for impeding movement of water outwardly over the peripheral edges of the underlying marginal edge region, as well as into nail mounting holes. The water barrier ridges are discontinuous so as to impede outward water movement, while allowing drainage of water in a downward direction. The wall covering panels further have various interlocking features which maintain sealing contact between overlapping upper and lower marginal edge regions and which facilitate alignment and mounting of the panels on the support surface.
