Abstract: VALVE BLOCK             ABSTRACT OF THE DISCLOSURE          A compact valve block for an IS glass forming machine in which a plurality of vertically positioned poppet valves which are in two rows and in staggered array, are con-trolled by solenoid operated pilot valves of equal number to the poppet valves.  An air manifold communicates with all of the poppet valves and the air is selectively delivered to the "kiss block" of an IS machine to provide the functional operation of various mechanisms on the machine.  The de-energization of the solenoid operated pilot valve associated with any of the poppet valves permits the poppet valve to return under spring pressure to connect its output passage to an exhaust passage.  All the exhaust passages on all of the poppet valves enter a common header which in turn communicates with an exhaust chamber, thus muffling the sound of air normally associated with the exhaust of the pneumatic motors of an IS machine.

The apparatus includes a deviation amplifier responsive to the departure of the process-variable signal from a set point produces an error signal the magnitude and polarity of which depends upon the extent and direction of departure of said process-variable signal from the set point.  A triangular wave signal is produced by a triangular wave generator.  A modulator which includes an error signal polarity detector for producing a first steady signal at a first terminal when the error is of one polarity and for producing a second steady state signal at a second terminal when said error signal is of the opposite polarity.  This modulator further compares the triangular wave signal with the absolute value of the error signal for producing at a third terminal, a signal the duration of which var-ies in accordance with the relative magnitudes of the error and triangular wave signals.  An output circuit produces bidirectional direct current pulses, the direction and duration of which vary in accordance with the polarity and amplitude of the error signal.

Abstract: COLUMN CHROMATOGRAPHY SPECIFIC BINDING ASSAY METHOD AND TEST KIT ABSTRACT OF THE DISCLOSURE A specific binding assay method and test kit for determining a ligand, such as an antigen or antibody, in, or the ligand binding capacity of, a liquid medium, particu-larly a body fluid such as serum, wherein the unknown ligand competes with a labeled component, such as a radio-labeled form of the ligand or of a binding analog of the ligand, for binding with a binding partner, with the im-provement that separation of the resulting bound-species and free-species of the labeled component is accomplished by drawing the liquid reaction mixture into a column of an adsorbent material selective for one of the two species. Separation results by immobilization of the selected species at the beginning portion of the adsorbent column while the other species is transported farther along the column by advance of the reaction mixture. The present method is manipulatively simple and advantageous over the many known techniques; finds special application to radioimmunoassay, particularly for detecting low molecular weight ligands; and is readily adaptable to automation.

Abstract: ABSTRACT OF THE DISCLOSURE      An electric injection carburetor is disclosed. Unmetered fuel under pressure is quantized for primary metering by an electronic fuel injector and input to metered fuel chamber.  The quantization occurs by controlling the duration of the opening time of the injector by an electronic control unit responsive to speed and manifold absolute pressure informa-tion.  Secondary metering is provided as a function of the mass air flow through the throat of the carburetor by an actuator assembly controlling fuel input to the carburetor from the metered chamber.  The actuator provides the secondary metering by changing the bias pressure on a flexible diaphragm producing a closure force on a needle valve that varies the flow of fuel from the metered chamber to an atomizing discharge nozzle in the throat of the carburetor.
