Abstract: ABSTRACT OF THE DISCLOSURE Improved machine and method for longitudinal compressive treatment of webs employing a two roll drive nip.  Specially ar-ranged initial parts of one or a pair of stationary retarding members are positioned at the exit side of the drive nip in the region of minor divergence of the roll surfaces to provide damming forces.  The initial part of the retarding member, preferably a curved, resilient nipping element, is shaped to oppose the flow of the web.  By its construction and position close to the line of centers of the rolls, it establishes a very compacted column ex-tending upstream to an initial treatment point continually located in the drive nip, between the moving surfaces of the rolls.  In this region longitudinal compressive action occurs upon the web in a continuous and uniform manner, preferably with compensatory action in response to variations in the forces exerted by the compacted column of web.  This compensatory action is provided by resilient deformation of a retarding member in the direction normal to the plane of the web, resilient adjustment movement of a retarding mem-ber in the direction away from the nip roll center line, and in some cases, by resilient response of the compacted material itself.          The retarding members may accomplish their resilient movement by swinging about the roll axes and by moving longitudinally of the web flow path.  The retarding member, or the leading member of a pair, preferably, in the start-up position, has its initial part located upstream of the running position.  Preferably, where a spring retarding member is used, its radius of curvature decreases abruptly toward its upstream end or is supported at its tip by a resilient pad; it is supported by a blade member on which its up-stream part may slide; it is continuous widthwise of the web being processed; it conforms to the curvature of the opposite roll when exposed directly to it; and it may have a roughened surface, in particular when only a single retarding member is employed.  Vibra-tory, steaming and other advantageous treatment conditions are readily associated with the machine.

Abstract: Abstract In the detection of Radon gas it is common for the radon sample to be admitted to a dark chamber the sides of which are coated with a 'phosphor' (silver activated zinc sulphide or equivalent). the resultant light flashes(caused by the alpha emanation striking the 'phosphor') are then counted by a highly sensitive light detector such as a photo multiplier tube.  The auxiliary circuitry for the photo multiplier tube is expensive, there is a problem of the phosphor being contaminated by build up of Radon daughters and a problem of light contamination in changing chambers in the field .            In this invention, a less sensitive but economical solid state optical sensor is used and an increase in sensitivity obtained by depositing the 'phosphor' directly upon the optical detector.  This may then be sealed with a thin metallic deposit that is opaque to light but semi transparent to alpha emanation.  The reduced sensit-ivity due to reduced surface area may be compensated for by longer periods of observation.

Abstract: ABSTRACT OF THE DISCLOSURE             Nitrogen and sulfur compositions are described which are useful in aqueous acidic plating baths and processes for electrodepositing bright and level copper coatings.  The compositions are prepared by reacting a mixture of (a) a disulfide having the formula [RR'NCS2]2                      (Formula I) wherein R and R' are each independently hydrogen, alkyl or aryl groups, and (b) a halo hydroxy sulfonic acid having the formula X(CH2)nCHOH-CH2SO3M           (Formula II) wherein X is a halogen, n is one or two and M is hydrogen or an alkali metal, and (c) an aliphatic aldehyde containing up to three carbon atoms, in (d) an aqueous alkaline medium. Particularly bright and level deposits are obtained with these compositions containing an aliphatic aldehyde containing up to three carbon atoms.  The presence of the above-described bright-ening and leveling agents in acid copper plating baths produces a lustrous, smooth and level deposit of copper over a wide range of current densities, particularly when wetting agents are included in the plating baths.

Abstract: D-21,030 A FAST REDUNDANT PULSE DENSITY ANALYZER   by Gerard J. Miille ABSTRACT OF THE DISCLOSURE           A self-checking pulse density analyzer includes substantially similar first and second threshold detection circuits, each of which have one input connected to receive incoming pulse information to be analyzed, and each of which provide the same binary signal state at a separate output terminal, when the pulse density reaches a predetermined level.  Each output terminal is connected to a separate input terminal of a threshold equalizing circuit and to respective inputs of first and second gating circuits.  The threshold equalizing circuit is activated by the binary signal from the faster acting threshold detection circuit to speed up the operation of the slower threshold detection circuit  and, thus, minimize the difference in operating time between the two circuits.  These two nearly simultaneous binary indications cause the first gating circuit to operate and, thus, provide a particular binary output signal indicative thereof.  When the binary indications are substantially separated in time, or if one does not occur, the second gating circuit is effectuated to indicate a failure of one threshold detection circuit.
