Abstract:
Microelectromechanical (MEMS) switches are used to implement a flying capacitor circuit transferring of electrical power while preserving electrical isolation for size critical applications where transformers or coupling capacitors would not be practical. In one embodiment, the invention may be used to provide input circuits that present a programmable input impedance. The circuit may be modified to provide for power regulation.
Metal Composites With Fly Ash Incorporated Therein And A Process For Producing The Same
The invention is directed to a process for producing metal composites from low-cost earth products and articles manufactured thereby. Fly ash from burned coal and oil is bonded with low-melting metals or alloys to produce economical composite materials with modified strength, conductivity and wear resistance.
Process For Modifying The Surface Of Metal Or Metal Alloy Substrates And Surface Modified Products Produced Thereby
A tightly bonded abrasion resistant surface layer is formed on, or a binding layer is formed therebetween, reactive metal or metal alloy substrates. A powdered mixture of oxides, at least one of the oxides having a heat of oxidation lower than the heat of oxidation of the oxide of the substrate, is disposed on the substrate. The substrate with the oxide powder disposed thereon is heated to a temperature lower than the melting point or solidus temperature of the substrate. The powdered mixture of oxides preferably comprises fly ash. An abrasion resistant surface layer may be bonded to a structural part by mixing the powdered mixture of oxides with powdered rective metal or reactive metal alloy, disposing the resultant mixture on the part, and heating.

Assignee:
National-Standard Company - Niles MI
International Classification:
B22D 1106
US Classification:
164461
Abstract:
A method of forming filaments, particularly continuous strips, sheets or the like, by rotating a chill wheel against a meniscus of molten material formed about the periphery of an elongate orifice through which the molten material is fed under uniform fluid pressure along the longitudinal axis of the orifice. Filaments of different widths, thicknesses and composite structures are extracted by utilizing single or plural chill wheels in conjunction with plural orifices.

International Classification:
B22D 1106
US Classification:
164 87
Abstract:
A method and apparatus for producing filamentary articles from an open bath of molten material. A quench wheel having a peripheral chill surface is rotated upon the surface of a portion of the bath provided with a baffle that defines a puddle of molten material free from fluid turbulence, thereby permitting high production rates and precise control of product configuration.

A chill block melt spinning apparatus produces flake-type powder of the smallest magnitude by centrifugal disintegration of molten metals and alloys. Molten metal or alloy is delivered to a rotating cup which centrifugally forces the metal to exit the cup tangentially in a sheet which breaks up into streams and then into a series of droplets. Rotating chill cylinders are radially spaced from the rotating cup. The cylinders receive the streams or droplets of semi-solidified metal and provide a fresh surface for each droplet to chill the droplets, forming ultra fine flakes while deflecting the flakes downward into a collecting area. The cylinders have a concave outer surface which corresponds to the shape of the rotating cup to provide an equidistant travel path from the rotating cup to a deflection contact surface for the radially travelling droplets.
