Abstract: Abstract of the Disclosure A process is disclosed whereby an improved platinum metal-containing catalyst is prepared.  According to the process, a supported platinum metal catalyst is contacted with a hydroxylammonium salt, e.g. a sulfate, and a sulfur-containing compound, e.g. a salt of sulfurous ac??, di-thionous acid or thiosulfuric acid, which liberates sul-furous acid under acidic conditions, in a mine?al acid medium.  The process is conducted substantially in the absence of reducing agents capable of reducing sulfurous acid to sulfide and is conducted under an atmosphere of inert gas.  The sulfur compound is present in an amount corresponding to 15 to 150 atom ? sulfur based on the amount of platinum metal.

Abstract: ABSTRACT OF THE DISCLOSURE           This disclosure depicts methods and structures for applying a very thin layer of electrically conductive, light-reflective metal such as aluminum to the phosphor screen of a cathode ray tube.  More particularly, there is disclosed the application of such a metal layer by the transfer of a metal layer formed on a substrate directly to a phosphor layer on the inner surface of a cathode ray tube faceplate.  The metal layer is adhered to the phosphor layer by an adhering step which may involve the use of a pressure-sensitive adhesive.          In one embodiment disclosed, the substrate is then stripped off; alternatively, the substrate may be removed by dissolution or volatilization.  Remaining volatile substances are driven off in a baking operation.  Other associated and alternative operations are depicted.

Abstract: A B S T R A C T     A controller for fluid pressure operated device such as power steering systems. The controller is of the type having a primary, rotatable valve member and a follow-up valve member, the valve members defining a neutral posi-tion.  The follow-up valve member is coupled to the primary valve member for limited movement relative to the neutral position.  The controller further comprises a fluid meter including a metering member for measuring the volume of fluid passing therethrough, the metering member being coupled to the follow-up valve member.  The controller has an inlet port and first and second control fluid ports which may be connected to the opposite ends of the power steering cylinder.  The primary and follow-up valve members cooperate with the hous-ing to define a first plurality of fluid passages providing fluid communication between the inlet port and the first con-trol fluid port through the fluid meter when the valve members are relatively displaced in one direction from the neutral position and providing fluid communicating between the inlet port and the second control fluid port through the meter when the valve members are relatively displaced in the other direc-tion from the neutral position.  The first and second plur-alities of fluid passages provide substantially the same length of fluid flow path between the inlet port and the correspond-ing control fluid ports in either direction of displacement of the valve member from the neutral position to provide uniform response in either direction.  Preferably, the first and second pluralities of fluid passages are arranged in substantially a mirror image of each other with respect to an imaginary plane perpendicular to the axes of rotation of the valve members, to minimize steering wheel precession.  In addition, the valve members maintain axial separation of the fluid flowing to a control fluid port and the fluid returning from a control fluid port to minimize internal leakage.

Abstract: Abstract:  Described is a dry dessert mix composition for use in preparing a tangy or yoghurt-like dessert by recon-stitution of the mix with milk and comprising a pregelatinized starch, an edible acid and a hydrocolloid gum.           In recent years, instant pudding mixes which rely on the use of thickeners and milk coagulating agents and coagulating accelerators and thereby eliminate the need for cooking by the housewife have become widely available and accepted.  These pudding mixes, however, are usually limited to the non-sour type flavors such chocolate, vanilla, etc.           Further, although liquid yoghurt analogs and yoghurt-like products may be made with direct acidification, this manufacture involves rather complex liquid phase processing and results in a perishable product similar to commercial yoghurt.  Dry mix products, on the other hand, require either low levels of acid or acidogens like glucono-.delta.-lactone.  A major problem with making a yoghurt-like product by direct addition of acid to milk is that the larger quantities of acid required to give a yoghurt tartness results in the precipitation of the milk protein (curds and whey).     It appears that due to curdling of milk when its pH is lowered below the isoelectric point of milk protein, the prior art restricts the use of an acidulent in a milk-based dessert, particularly when a dry mix is to be employed.          Also described is a dry beverage mix composition for use in preparing a tangy beverage by reconstitution of a mix with milk or a milk substitute.

Abstract: ABSTRACT OF THE DISCLOSURE           In an air diffusion system for lagoon treatment of sewage or industrial waste, a radial configuration of flexible diffuser tubes eliminates short-circuiting by automatically producing a flow pattern extending well beyond the radial extent of the diffuser and over the sloping sides of the lagoon in particular.  A preferred diffuser comprises an inner perforated conduit surrounded by a fabric tube through which air is released into the liquid.  Providing a space between the conduit and the fabric tube and filling the space with gravel pellets provides for greatly improved uniformity in air diffusion.
