Abstract: A rubber liner for preventing build-up of materials, such as gypsum, in handling or storage facilities, comprises, by weight, 100 parts of a rubber elastomer, 10 to 30 parts of a fluorine-containing polymer and 5 to 20 parts of a compatible oil compound. Preferably, the liner also contains from 2 to 15 parts of a compatible grease. For improved adhesion to metal surfaces such as tanks and pipes, a laminate is made utilizing said non-stick rubber liner as an outer liner, utilizing a diffusion-resistant hard rubber layer as an intermediate layer, and utilizing a soft rubber layer designed for maximum rubber-to-metal adhesion as an interior layer.

Abstract: A sensor for determining the presence of a particular volume of fluid within a plurality of reservoirs maintained as a portion of an automatic mixed drink dispenser. Fundamentally, the invention includes electrical contacts maintained within each of the various reservoirs, the reservoirs being aligned into rows and columns to form a matrix. A multiplexing circuit is interconnected to the rows of such reservoirs while a sensing circuit is interconnected to the columns thereof. The addressing of the rows of reservoirs by the multiplexer enables a signal to pass across the contacts and through the beverage maintained within the reservoirs, this signal being sensed by the sensing circuit interconnected between the columns of reservoirs. "Empty" reservoirs, or those having a low beverage level, may be quickly isolated by a determination of the row accessed and the column sensed to result in the failure of a contact to pass a signal.

Abstract: A process wherein air, oxygen-enriched gas, or oxygen is ozonated by an ozone generator operating at reduced flow rate with the result being an increased concentration of ozone being produced. The ozone is fed to a fluid dispersing system containing a flat plate orifice which creates a downstream vena contracta. Addition of the ozonated gas into the vena contracta produces a highly efficient mixing device.

Abstract: A high molecular weight polyester is disclosed, having a low carboxyl content, and utilizing a low catalyst level, produced by a two-stage process; a melt process until the intrinsic viscosity of the prepolymer reaches about between 0.15 and 0.45 dl/g, and a solid state polymerization in a fluidized bed until the intrinsic viscosity of the polycondensed polymer reaches at least 0.60 dl/g. The melt process employs addition of excess initial glycol, delayed addition of excess glycol, and delayed addition of catalyst, in any combination, to achieve a low carboxyl content polyester prepolymer capable of use in the fluidized bed solid state polymerization. This prepolymer with a minimal carboxyl content achieves a maximum solid state polymerization rate in a fluidized bed. This prepolymer also permits the use of a very low catalyst level to achieve high product purity and still maintains economically satisfactory polymerization rate.

Abstract: Apparatus for testing the authenticity of paper having colored areas thereon. A plurality of light emitting diodes, each emitting light of a different wavelength, are provided in juxtaposition to a paper having areas thereon which are reflective with respect to the light from the various diodes. A single photodetector is maintain closely adjacent the paper for receiving light reflected therefrom. A sequential timing circuit controls the illumination of the diodes such that the photodetector senses the light reflective characteristic of the paper with respect to each of the various wavelengths of light in a mutually exclusive manner. The outputs of the photodetector are passed to a sample and hold circuit which, at the end of a test cycle, maintains data relative to the light reflective characteristics of the paper for each of the various wavelengths of light.

Abstract: An apparatus for the treatment of purification of a fluid by treatment with a treating fluid in a flow pipe. The flow pipe has a flat plate orifice located therein, which orifice has an internal diameter of from about 0.7 to about 0.9 of the internal diameter of the pipe. A vena contracta portion is located in the flow pipe at a distance of from 0.25 to 0.5 pipe diameters downstream from said flat plate orifice. An injection nozzle for introducing the treating fluid into the flow pipe extends through the flat plate orifice with the tip of the injection nozzle being located in the vena contracta portion so that the fluid is thoroughly treated by the treating fluid.

Abstract: An improvement to the hydraulic power apparatus for hydraulic presses is provided, wherein the seals and various gaskets for containing the hydraulic fluid in the press has an enclosed container substituted therefor. This enclosed container, in communication with hydraulic fluid reservoirs, provides the pressure for the ram in the hydraulic press. The container is inflatable with the pressure on the hydraulic fluid, but which fluid is never in direct contact with any of the structural mechanisms comprising the hydraulic power apparatus. The hydraulic power apparatus, hence, can be modified to increase the dimension of the ram to remove the gasket mechanisms and to provide an installation hatch which facilitates serviceability to the inflatable container.

Abstract: The polyesters are endcapped by reacting them generally with substituted benzoyl-lactams or substituted benzoyl-phthalimides at a temperature usually above the melting point of the polyester to form a benzoyl end group. Such endcapped polymers have improved properties such as thermal-oxidative aging, molecular weight retention, tensile strength retention, and improved stability.

Abstract: The invention relates to the use of reinforcing cords associated with the pneumatic tire to control radial force variations in the tire under loaded conditions, and the method of applying such reinforcing cords woven in a warp and weft relationship cut in a bias shape to form a belt, such belt extending past the lateral edges of the present belt and applied to the tire either in its new form or as a retreaded tire from an old carcass. It can be extruded into the tread material as it is initially formed. Basically, the cords are made from a very high strength material, either synthetic, wire, or the like, having a tensile strength of approximately 125 psi each, with the cords spaced at approximate 1/4 inch spacings. Hence, there will be four cords, more or less, per inch. The cords could be increased to 150 or more pounds each. There will be approximately 20 to 40, depending upon the width of the tread area of the tire involved and the width of the normal belt ply in the radial or bias ply tire involved.
