Abstract: A gantry is constrained to move around the walls of a cylindrical, concrete tank. A rotating, high pressure water spray nozzle is mounted to a moveable platform on the gantry and connected to a source of water at a pressure of over 20,000 psi. The distance between the nozzle and an opposing surface of the wall of the tank is selected so the nozzle can remove the surface of the concrete and produce a selected surface roughness. The platform is moved vertically, with the gantry moving around the tank, so the surface of the concrete is systematically removed and roughened. A shotcrete or gunnite sprayer is then mounted to the platform, and the roughened surface sprayed with shotcrete or gunnite which sticks to the roughened surface. A tensioning head is then mounted to the platform, and wires or cables are tensioned as they are wrapped around the walls.

The apparatus includes a refrigerated curved surface that is brought into contact with water to form a thin, substantially uniform, ice sheet on the surface.

These ice particulates enter into an inlet where they are fluidized and drawn into a manifold that extends substantially along the length of the harvesting blade. The manifold partitions the particulates into separate delivery tubes where they are ejected from nozzles to the workpiece. The manifold can be created to either evenly or unevenly distribute ice particulates to the delivery tubes.

Abstract: An apparatus and method that enhances removal of contaminating particles from surfaces of a non-electrostatically sensitive components that are cleaned using a carbon dioxide cleaning spray. The apparatus includes a programmable power supply that is connected to ground and to the non-electrostatically sensitive component. The surface charge of the component is determined by cleaning the surface without adding any voltage or charge bias to the component.

Thus, reversing the polarity of the charge on the surface that is to be cleaned removes the strong attraction between the contaminating particles and the surface and enhances removal of the contaminating particles from the surface.

Abstract: A method of bonding together metallic glass laminations to form a stack and thereafter shaping the stack, for example, by cutting, to form a bulk object such as a wound stator or rotor of an electric motor. Metallic glass is an amorphous ferromagnetic material used in the construction of electrical equipment to reduce core losses. The method involves coating individual laminations of metallic glass with a temperature resistant, non-gas producing metal bonding agent, stacking the coated laminations, applying a pressure to the stacked laminations such that the bonding agent does not exude from between the laminations, allowing the bonding agent to cure, and thereafter shaping the stacked laminations as required. In some cases, temperature resistant wiring and insulation are fitted to the shaped laminations and heated to a temperature sufficient to anneal the metallic glass. The laminations are shaped by cutting with a mixture of fluent material and abrasive material emitted from a nozzle at high pressure.
