Abstract: Case    1392 Abstract of the Disclosure Improved apparatus for imparting visual surface effects to a relatively moving substrate material by appli-cation of discrete streams of heated pressurized fluid, such as air, to surface areas of the material.  An elongate manifold assembly, comprising a pair of elongate manifold housings and a plurality of spaced, parallel fluid stream discharge channels, is disposed across the substrate path.               The manifold housings, coupled in fluid tight relation, are constructed and arranged so that any distortion of the manifold assembly caused by differential thermal expansion is resolved to minimize displacement of the manifold to-ward or away from the substrate.  Pressurized cool fluid, such as air, is directed into selected manifold discharge channels to block selectively the passage of pressurized heated air therethrough.  The manifold is provided with heated air outlets which communicate by passageways with the manifold compartment to continuously bleed off heated air from the manifold, thereby counteracting localized cooling of the manifold adjacent the discharge channels and reducing pressure build up within the manifold when selected of the channels are blocked with the cool air.

Abstract: ABSTRACT OF THE DISCLOSURE            Process for pulling cables into conduits A method for reducing the friction between a conduit and a cable while the latter is pulled into the conduit consists of locating a layer of balls on the surface of the conduit or cable before laying. The balls have a diameter much lower than that of the cable, typically of the 0.1 to 1 mm range.  The balls may be adhered to the cable as it progresses into the conduit, using for instance electrostatic forces.  The balls may as well be blown into the conduit to form a carpet before the cable is forced into the tube.  In both cases, friction is reduced whatever the angular portion of the conduit which is contacted by the cable during pulling.

Abstract: ABSTRACT        This invention relates to a composition for the purification of water which includes a suitable coagulant for coagulating solid impurities dispersed in the water to form flocs.  It also includes an organic hydrophilic colloid capable when dispersed in the water, of absorbing large quantities of water to form a sol for aggregating the flocs, the proportion of organic hydrophilic colloid in the composition being such that when the composition is used to purify the intended quantity of water, the organic hydrophilic colloid does not interfere with coagulant dispersal in the water or with  floc formation.  The invention also relates to a method of purifying water which includes clarifying the water by dispersing the composition in the water to be treated to flocculate suspended solid impurities therein, and separating the flocs from the clarified water, the quantity of composition added being such that the quantity of colloid in the water does not exceed 50mg/litre.

Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed a method of using an exhaust gas catalyst for treatment of exhaust gases developed by burning a hydrocarbon based fuel in an internal combustion engine.  These exhaust gases contain varying amounts of unburned hydrocarbons, carbon monoxide and oxides of nitrogen depending upon the operating conditions of the internal combustion engine.  This specification teaches the use of an improved catalyst composition in which a support medium is provided for supporting the catalyst system, the support medium having an upstream support portion and a downstream support portion over which the exhaust gases pass in succession.  The upstream support portion of the support medium has deposited thereon palladium and the downstream support portion of the support medium has deposited thereon palladium and tungsten. Tungsten is present on the downstream support portion of the support medium in a quantity such that tungsten is available to substantially all of the palladium on that portion of the support medium.  The catalyst system has particular utility as n three-way catalyst operating at approximately stoichiometric conditions or as a catalyst for use in conjunction with the so-called "fast burn/low friction" engines or as an oxidation catalyst.
