    Abstract: In one form, a cylindrical shell extends from an annular burner body to form an elongated combustion chamber, which chamber bears a cylindrical heat radiator element concentric with and spaced radially inward of the shell. A tube coupled to the opposite end of the annular burner body delivers compressed air born abrasive particles to a reduced diameter inlet passage within the burner body. The burner body bears a tubular, slotted sand separator which permits air free of sand to pass along the rear side of the heat radiator for re-entry through radial holes within the heat raditor downstream of the burner body for combustion stabilization. In another form, the combustion chamber is at right angles to the flow passage including the tubular, slotted sand separator and the discharge nozzle. The products of combustion from the combustion chamber at high temperature and velocity, aspirate the abrasive flow through the discharge nozzle.

    Abstract: A method and apparatus are provided for controlling the maximum power of a hydraulic windmill which is achieved by utilizing the overpressure created in a closed loop hydraulic energy conversion system to rotate the tail of the windmill away from its operating plane to reduce the power transmitted from the wind to the blades of the windmill. A mechanical braking mechanism may be applied to the windmill blade driven rotatable shaft upon a sensed overpressure in the hydraulic fluid which acts through a differential between the hydraulic overpressure and a preset pressure to effect closure of the brake.

    Abstract: HVOF torches introduce fuel and oxidizer reactants into a central passage so as to form a concentric stream having an axial stream of oxidizer surrounded by an annular stream of fuel that is positioned against a sidewall that bounds the central passage. The fuel can be introduced so as to swirl about the axial stream of oxidizer. The torch can be formed by a body having the central passage therethrough and an insert residing in the central passage and having an oxidizer passage therethrough. A portion of the insert can have a reduced cross section so as to form an annular fuel chamber, from which the flow of fuel into a passage first section is restricted so as to distribute the fuel against the sidewall. The torch can be provided with a cooling jacket to prevent damage to the body.

    Abstract: A plasma jet or a supersonic flame jet emanating from an internal burner combusting compressed air and fuel is applied to a solid rod coaxially within the flame or plasma jet to heat, atomize and project a spray of initially liquid droplets of the rod material separating from the tip of the rod in the direction of a workpiece for impact against a workpiece surface for solidification to form a coating thereon. The process involves the control of the transit of the initially liquid droplets from the tip of the rod over the path of travel to the surface of the workpiece to ensure that at the moment of impact against the surface of the workpiece the rod material particles are least partially solid. The stand-off distance may be set to ensure that the initially liquid droplets pass through an upstream liquid region and a contiguous downstream transit region to effect the partial solidification of the molten liquid droplets prior to impact. The control of the transit of the initially liquid droplets may be effected by adding a liquid or gas coolant into the jet stream to cool both the jet stream gases and the initially liquid droplets downstream of the point where the liquid droplets separate from the tip of the rod.

    Abstract: An internal burner combusting an oxy-fuel or air-fuel mixture, or a plasma heat source providing a supersonic flame jet which when expanded to atmospheric or lower pressure is characterized by a static temperature well above the melting point of a material in particle form being sprayed by the flame jet and the step of reducing the flame jet temperature after reaching supersonic velocity to a temperature below the melting point of the material prior to feeding of the material particles into the flame jet. The jet temperature reduction may be effected by injecting directly into the flame jet stream an amount of liquid or gas fluid which will reduce the flame jet temperature by the required amount. Alternatively, the supersonic flame jet may be passed through a concentric heat exchanger bearing a coolant medium such as water to absorb the necessary amount of heat from the flame jet to reduce the flame jet temperature to below the melting point of the material.

    Abstract: A surface discontinuity is formed along an anode nozzle bore sufficiently upstream of a nozzle exit orifice and of a sufficient size to cause an arc between an electrically conductive end wall of a plamsa-arc torch anode nozzle passage and a coaxial cathode coaxially mounted by an opposite end wall of the torch cylindrical casing having a gas under pressure and at an established vortex flow to pass through the nozzle passage. A boundary layer of the vortex flow of gas along the anode bore wall provides a path for the arc to pass directly to the anode nozzle passage at or just downstream of the disturbance zone provided by the nozzle passage wall surface discontinuity. A counterbore may extend along a portion of the nozzle axis from the nozzle exit axially inwardly to form a radial shoulder with the main bore of the anode nozzle and define the discontinuity. Alternatively, a shallow annular groove may be machined into the anode nozzle bore, or an annular ring may project radially inwardly of the nozzle passage bore to constitute such alternative surface discontinuity. Material may be sprayed into a high velocity hot gas stream downstream of the arc column and its downstream ionized region to eliminate excessive heating of the particles sprayed by the torch. A reduced diameter nozzle bore section may be provided between the terminus of the arc column and/or its associated downstream ionized region and the point of the introduction of the material to be sprayed, with the reduced diameter nozzle bore forming a nozzle throat of an expansion nozzle producing a supersonic jet stream at the nozzle exit.

    Abstract: The present method and apparatus for producing a supersonic jet stream introduce an oxidizer in such a manner as to create a vortex, which is then restricted. Fuel is introduced into a reduced pressure eye of the vortex, forming a stratified composite stream of gases with unmixed oxidizer surrounding an inner mixture of fuel and oxidizer. This stratified composite stream is passed down a tube that exhausts to a low pressure environment. The combined fuel and oxidizer in the stratified stream is ignited to provide a high-velocity stream of combustion products. The outer layer of unmixed oxidizer in the vortex shields the tube and reduces or eliminates the need for additional cooling.
