Abstract: Abstract of the Disclosure A fabrication arrangement using plural LSI chips to make a bit stream detection system requiring a programmable logic array which is too large to fit on a single LSI chip.  Due to the small number of input/output pins avail-able on any LSI chip, the fabrication arrangement divides among the chips an input shift register, the array, and array input latches.  Each LSI chip also has time-multiplexed array outputs and time-multiplexed feedback inputs that minimize the pins and enable interconnection among the array section outputs on the chips so that they combine into the single large array required by the detection system.  These LSI chips can be identically fabricated.

Abstract: WOUND RESISTOR-CAPACITOR NETWORK       AND METHOD OF FORMING            Abstract of the Disclosure A wound resistor-capacitor network having stable frequency response over a wide frequency range (e.g., 60 cycles to 100 kilohertz), is produced by forming a pair of aligned circumferentially extending resistance paths in one of two strips of metallized dielectric film.  Forming of the resistance paths is accomplished as the two metallized strips are being wound to form an R-C network roll, by removing metal from the one strip along a first line to produce a gap in the metal layer in parallel spaced relationship to an adjacent edge of the film.  Subsequently, removal of metal from the first strip also is initiated along a second line spaced inward from the first line, to produce another gap in the metal layer, thereby forming an elongated first path of desired resistance between the two lines.  Metal removal along the first line then is temporarily interrupted to provide a lead termination area and a current steering path at the adjacent end of the network roll, on either side of the strip midpoint.  Metal removal along a third line in alignment with the first line then is continued until an elongated second path of desired resistance has been formed between the second and third lines, at which time metal removal along the second line is terminated.  Lines of metal also may be removed from the second dielectric film to provide a lead termination area and a current steering path at the opposite end of the wound network roll.  Preferably, the metal is removed with the split beam of a single laser and the lines of removal are symmetrical on opposite sides of each strip's longitudinal midpoint.

Abstract: ABSTRACT OF THE DISCLOSURE            A system for the detection of precipitate-forming anti-gens by means of the reaction with their corresponding antibodies is disclosed.  The reaction of precipitate-forming antigens with their respective antibodies produces a precipitate in proportion to either the antibody concentration or the antigen concentration, depending on which is present in excess.  The method does not require formation of actual precipitate, but measure the forma-tion of "scattering centers" -- i.e., molecular aggregates of sufficient size to produce measurable scatter of light.  The quantity of scattering centers formed is measured by nephelometric means and the measuring system performs and immunonephelometric analysis.  In particular, the rate of change of the nephelometric signal with respect to time is measured and the peak rate and time to the peak rate established.  From these simultaneous measurements both the antigen/antibody concentration and the condition of antibody or antigen excess are determined.
