Abstract: Disassemblable rolling mill stand, of the type involving a bedplate structure with a substantially “U”-shaped embedding structure (1), within which the rolling mill assembly is embedded and fixed (2), with at least one couple of horizontal rolling cylinders (210–310), by fixing means (202-10/12), of said substantially “U”-shaped embedding structure, which extends upwards at least up to the upper horizontal cylinder axis of said couple of horizontal rolling cylinders (210–310) and makes up vertical sliding jointed guide elements (11–110) with corresponding opposite vertical counter-guides (201) in the rolling mill assembly (2).

Abstract: An injection spraying system for mixing additives in controlled amounts to water for spraying, which improves handling and calibrating of the concentration of the mixture. The system includes a water tank, mixing globe, pump device, unloader chamber and a worm reduction element for reducing pumping of one gallon of water into one revolution of a drive shaft. The shaft extends through a clutch device and a plurality of injection chambers. The injection chambers supply and meter the amount of additives injected. Rotation of the shaft through the injection chambers loads a set amount of additives for suction into a mixing globe. The unloader chamber controls the spraying cycle and by-pass cycle of fluid flow through the system. The present invention provides a versatile injection spraying system for multiple tasks. The types and amounts of additives sprayed can be easily adjusted without requiring adjustments to sensitive metering or measuring devices.

Abstract: A blasting apparatus includes a pressure vessel adapted to contain a particulate blasting medium and a liquid. The vessel includes an inlet and a bottom outlet. The interior of the vessel communicates via its bottom outlet with an opening in a conduit along which conduit an entraining pressurized gas can be fed from a pressurizing gas source. A pressurizing device is provided to pump liquid from a liquid source into the vessel behind its contents in terms of its contents' outflow from the vessel through the bottom outlet. A valve is provided to control the flow of pressurized gas along the conduit. Immediately upstream of the opening in the conduit is located a venturi so that the velocity of the pressurized gas is increased as it passes over the opening thereby increasing the quantity of particulate blasting medium entrained by the gas.

Abstract: A simplified hinging device and a temple bar thereby obtained, particularly for eyeglass frames, includes a prevalently metallic termination, which is widened, contoured, holed and bent according to a U shape, which engages, by means of a pivoting screw or one or more projections, another prevalently metallic termination, which is widened, contoured and holed, free to rotate about the axis of the aforesaid screw, pivot point or projection.

Abstract: A hot/cold water inlet and outlet structure for a ceramic core shaft of a single handled faucet has a valve housing, a switch valve set, a valve mount, an upper switch valve, a lower switch valve, and a sealing ring wherein the valve housing has a valve chamber disposed at the interior thereof for the switch valve set and the valve mount thereof to be adapted therein respectively.

Abstract: The composition includes fingi belonging to one or more species of fungi of the genus Trichoderma, selected from T. asperellum, T. atroviride, T. inhamatum and their mixtures, useful as an agent for the biological control of phytopathogenic organisms. The composition is suitable for protecting or treating plants and plant material against infections and diseases caused by plant pathogens, and/or to stimulate plant growth, and/or to induce systemic resistance in plants to diseases caused by phytopathogenic organisms, and/or to control biodeterioration agents of materials.

Abstract: A tendon receiving duct having a tubular body with a plurality of corrugations extending radially outwardly therefrom. Each of the corrugations is in spaced relationship to an adjacent corrugation. The tubular body has an interior passageway suitable for receiving single tendon therein. Each of the corrugations opens to the interior passageway. The tubular body has at least a first longitudinal channel extending between adjacent pairs of the corrugations on one side of the tubular body and a second longitudinal channel extending between adjacent pairs of the corrugations on another side of said tubular body.
