Abstract: A rotary-vane mechanism can include a rotor and a casing, wherein the rotor includes a drive shaft and one or more vanes. The casing can include a quasi-cylindrical tubular shell or a quasi-spherical shell, and can provide walls that support the drive shaft. The rotor can be mounted within the casing. The drive shaft can extend outward from the casing, wherein the drive shaft touches the inner surface of the casing in one or more contact locations, with the contact location(s) provided by a sealing plate. The casing can include intake ports, exhaust ports, ports for an ignition mechanism, wherein the intake ports are provided with one-way valves. The drive shaft can include one or more guide slots, which can penetrate through the drive shaft wherein the vane(s) is located inside the guide slot(s), and edges of the vane(s) can constantly touch the inner surface of the casing during a rotor rotation of the rotor.

Abstract: A method of producing a multi-microchannel, flow-through element, including the steps of providing a body of material, and producing multiple microchannels within the body, wherein the microchannels extend through the body to produce a multi-microchannel, flow-through element. Such an element can be used as a micromixer, a sensor element, a filter, a fuel element or a chromatographic element.

Abstract: A method of material treatment in which the surface of a metal substrate is converted to a composite structure of the metal and its nitride or carbide utilizing a high temperature chemically active thermal plasma stream, and the product obtained from that method. The complex thermal plasma contains controllable additions of active gas, liquid or solid substances. The surface layer obtained is functionally graded to the substrate resulting in an excellent bond that resists delamination and spalling, and provides a significant increase in hardness, wear and erosion resistance, and corrosion resistance, and a decrease in coefficient of friction.

Abstract: A cermet armor material for highly effective ballistic performance which is comprised of a layer of base metal in which is deposited a layer or layers of ceramic and a compatible metal such that the deposited metal in combination with the base metal forms a continuous matrix around the ceramic particles. The body has a structure which is continuously graded from a highest ceramic content at the outer surface (strike face) decreasing to zero within the base substrate, and contained no abrupt interfaces.

Abstract: The present invention provides a reusable mandrel and method of using the mandrel in a SFFF process. A thermally conductive feature is located on the surface of the mandrel. The mandrel does not bond to the deposited part so that it may be easily removed without damaging either the mandrel or the deposited part. The present invention further enables the manufacture of components where the deposition surface is produced to precision, net shape geometries.

Abstract: A method for producing porous materials which comprises directing a plasma stream containing particles of a base material in liquid or solid/liquid form onto a substrate under controlled conditions in which the particles spot weld to the substrate or to one another without full fusion, and establishing relative movement between the plasma stream and the substrate whereby the material is deposited as a porous structure of desired porosity and shape.
