Apparatus and methods are disclosed whereby a propellant driven water stream is used in the formation of materials made from high tensile strength alloys. High pressure developed in liquid flowing through a tubular work piece is employed to achieve desired forms. The high pressure results from superposition of compression waves generated in the course of the impact of the liquid by products of propellant combustion.

System and method for forming of tubular parts

A nozzle, comprising a housing; and an assembly including at least two deformable conjugated parts separated by a spacer seal, the assembly being arranged in the housing so as to form a nozzle outlet, the housing and the parts and the spacer seal being deformable so as to define a geometry of the nozzle outlet and seal surfaces between the parts and the spacer seal and between the parts and the housing; wherein the parts and the spacer seal are configured so that a force needed for inserting the assembly into the housing exceeds an assembly force that deforms of at least one of the housing and the assembly, and wherein the parts and the housing are deformed by the assembly force when assembled together to create a seal between the parts and the housing; and wherein the housing is fabricated from material having a lower hardness than the parts and the spacer seal.

A nozzle having a housing and an assembly including at least two conjugated parts separated by a spacer seal. The assembly is arranged in the housing so as to form a nozzle outlet. At least one of he housing, the parts, and the spacer seal are deformable so as to define a geometry of the nozzle outlet and seal surfaces between the parts and the spacer seal and between the parts and the housing.

The method of and the apparatus for the formation of a high-speed fluid or slurry jets of a desired geometry are invented. According to the present invention a fluid or slurry jet is formed by the expelling of a compressed fluid via a slot formed by two attached plates separated by the insertion. The shape of the slot is determined by the forms of the plates and the insertion. This shape is also determined by the deformation of the plates and the insertion by the external forces applied to the plates, for example by the fasteners connecting the plates.

A method for formation of slugs in a gun barrel and acceleration of these slugs up to the speed of 3 km/sec and more is suggested. A selected region of the barrel is filled by water or another liquid, mixture of liquids or slurry. The refrigerating media is supplied into a heat exchanger cooling the selected section of the barrel. The freezing conditions (rate of the heat removal, duration of cooling) assure desired cohesion of the slug and its adhesion to the barrel. When freezing is completed, the axial pressure is exerted on the internal edge of the slug. When the pressure exceeds the adhesion forces, the slug will move toward the open end with acceleration determined by the axial forces. If the exerted pressure force is not sufficient for the slug separation the expansion radial forces are applied to the barrel or the interface between the slug and the barrel is heated. After the separation the compressed media drives the slug toward the open end of the barrel. In the course of the motion the slug accelerates up to the maximal available velocity of the driving fluid. After exiting the barrel the slug impacts a target similarly to a striker or bullet. The impact conditions are determined by the slug velocity, dimensions, shape and structure and are selected to assure a desired material modification (penetration, fracturing, spallation, and plastic deformation). In the course of impact the slug is decomposed, melted and the generated liquid is removed from the impact zone.

The device for benign, non-surgical external shaping of corneal tissue to compensate, by refractive correction, for deviations from normal focussing. The jet is directed to erode corneal tissue to provide an increase in curvature to correct for far-sightedness i.e., to refocus a perceived image from beyond retina onto the surface of the retina.

A method of and an apparatus for heating, melting, waste disposal and production of gaseous fuel include supplying air, coal, steam and waste into a melt. The melt contains elements readily oxidized by air and producing oxides which are readily reduced by carbon. The overall results of the reaction of the elements oxidation and reduction consist in the production of CO containing gas and evolving heat. The heat evolved is extracted from the melt by submergence of solid to be heated into the melt, by injection of heated gases into the molten slag, by heat exchange between the wall confining the melt and gas, liquid or solid to be heated, or by conversion of steam into H.sub.2 and CO.

A method of heating gases for combustion, operating turbines, and heating of a material and the like comprises the steps of providing a melt deposited in a vessel including two vessel elements and selected from the group consisting of a metal, a slag which is a mixture of metal oxides and nonmetal oxides, and a metal and a slag, supplying coal, air, fluxes and hot flue gases into the melt, passing the flue gases leaving the melt through a gas heater, passing a gas to be heated through one of the vessel elements, circulating the melt between the vessel elements, and supplying the gas which has been heated during passing through the one vessel element, to a gas consumer.

Iron or steel products are produced from oxide ores in a unique process which utilizes air and regular coal as its primary energy source and wherein the ore is melted in a carbon dioxide zone for separation and absorption of the iron oxides into a slag which is transferred to a carbon-monoxide generating zone. In the latter zone the iron oxides are reduced to form the iron or steel product. Carbon monoxide containing flue gas from the latter zone is burned with air and utilized as a heat source in the carbon dioxide zone. Slag from the various unit processes is collected and used to preheat process air by either continuous operation or in a semi-continuous regeneration process. In both modes of slag preheating, flue gas is utilized to maintain the temperature of the slag bath and high temperature air preheating prior to the slag bath. The molten metal is refined by atomizing in slag or protective gas and may be formed into a sheet by extrusion through a slot-shaped orifice into a space defined between two perforated plates, with a protective gas injected through the perforations serving to support the metal sheet as it solidifies and cools. The thermomechanical treatment of the metal may be carried out by the simultaneous cooling and rolling in a protective atmosphere.
