Abstract: APPARATUS FOR FORMING BUILDING MATERIALS         COMPRISING NON-WOVEN WEBS                         Abstract A mixture of binder and fibrous material is introduced into the upper regions of a mat-forming zone. The mixture is intersected by a horizontally or upwardly directed air stream and entrained therein, then layered onto at least one foraminous wire by exhausting the entraining air through said foraminous wire or wires. By reducing turbulence and by controlling the manner in which the particulate matter is deposited upon the foraminous wires, uniform non-woven webs can be obtained which may be used in a variety of ways to form versatile building products.

Abstract: MULTIPLE COATING OF FIBERS            Abstract This invention relates to an improved method for forming two or more coating layers on a fiber.  A first coating liquid is applied by an applicator having a die that provides for the formation of a gap between the die and the first coated layer.  A second die is located at the exit of the first die, with the second coating liquid flowing onto the fiber through a relatively narrow clearance between the first and second dies.  The clearance is formed by die surfaces perpendicular to the fiber axis.          This second die also provides for a gap, so that the second layer is applied at a "free surface" at the point of contact with the first coated layer.  This approach eliminates turbulence and coating nonuniformities associated with prior art multiple coating techniques.            (Fig. 1)

Abstract: METHOD OF AUTOMATICALLY DETERMINING AND     CONTROLLING THE PRINT QUALITY OF A PRINTER                         Abstract The invention concerns a computer-controlled method of automatically determining the print quality value of a printer and of controlling the print quality value towards an optimum value DQopt, using both the empirically determined average optimum image contrast signal (PCS) and the standard deviation ? PCS. the average optimum image contrast signal is derived from the relation   where RB is the reflection of the background and Ri is the reflection of a picture element or dot i (PEL).  The actual value of the image contrast signal is derived from the individual values PCS =    for all n picture by optoelectronically scanning all picture elements i of a character along the skeleton line and the background, and deriving from these scanning values a factor        and a print quality factor   and deriving ln x2 from said print quality factor.            Subsequently the actual print quality value DQ = aO + a1 ? ln x2 is determined, and by iterative automatic comparison of the stored optimum print quality value DCopt and the print quality thus determined, control variables are derived and used in a closed control loop for adjusting the different printer parameters.

Abstract: Abstract of the Disclosure A method for the colorimetric immunoassay of antigen or antibody to be detected in a biologically derived fluid sample using a solid surface. Preferably, the surface is an impermeable surface of a dipstick. To detect antigen in the sample, a dipstick containing bound antibody is contacted with the sample and with a soluble enzyme-labeled antibody, to cause the antigen to bind to both the immobilized antibody and the labeled antibody on the surface. After separation of unreacted reagents, the solid surface is contacted with a substrate which converts from a soluble form to an insoluble colored form in the presence of the enzyme and deposits upon the surface of the solid surface. The solid surface is separated from the solution. The sandwich immunoassay technique may also be employed to detect antibody in the sample by reversing the roles of the antigen and antibody. The system is also applicable to a competitive binding technique.

Abstract: NOVEL POLYVINYL CHLORIDE SUSPENSION POLYMERIZATION PROCESS AND PRODUCT                ABSTRACT OF THE DISCLOSURE    A polyvinyl chloride having high bulk density and enhanced plasticizer absorption is produced by suspension polymerization of vinyl chloride monomer and comonomers wherein the initial suspension of ingredients is formed such that the oil phase droplets formed in the suspension are compositionally equivalent with respect to initiator, and the level of suspending agent and agitation are chosen to substantially   preclude agglomeration of resin particles throughout the reaction, thereby producing resin wherein the resin grain size distribution results directly from the oil phase droplet distribution created at the start of the reaction.  Seed particles of resin are introduced to the reaction mixture prior to establishing the final particle distribution.  The seed particles can be formed by polymerizing a monomer such as vinyl chloride and mixtures of vinyl chloride and copolymerizable monomers in the presence of a polymeric dispersing agent, and optionally a low boiling solvent which is a nonsolvent for the resin being produced.  The result of the process of the invention is a polyvinyl chloride polymer or copolymer that has high bulk density and enhanced plasticizer absorption.  A further benefit of the process is that resin deposition on the interior surfaces of the reactor is essentially eliminated.

Abstract: ABSTRACT A noise thermometer/thermocouple-detector is improved by arranging for the feed lines for the noise resistor to shield the legs of the thermocouple. Typically each thermocouple leg is surrounded by insulation and then an outer conductor serving as a feed line to the noise resistor.  Alternatively, only one of the thermocouple legs may be so shielded in which case a protective outer cover of the detector may serve also as the other leg and a second feed line for the noise resistor.  The invention gives improved characteristics over the prior art in which the same conductors are used both for the thermocouple and the noise resistor.

The decoder provides synchronous detection of the (L-R) information, combined two-mode phase-locked loop (PLL) recovery of the carrier component and enabling of the (L-R) signal output, and delayed enabling of the (L-R) signal output for a "stereo bloom" effect.  The decoder is particularly useful for decoding independent sideband (ISB) AM stereo broadcast signals.
