    摘要: An apparatus for solder joining metal tapes to form laminated metal tapes comprises an alignment box having a base and a sidewall means extending therefrom to define a tapered inner channel extending through the box. The tapered channel having an entrance end and narrowing to an exit end. At least one tapered wall extending from the base and within the inner channel to define subchannels that are spaced at the entrance end and converge into the inner channel before the exit end. The sidewall means and tapered wall extending from the base to respective wall tops, and a cover extending over the channel and subchannels is mounted on the wall tops. The base, sidewalls, inner wall, and cover being configured to form the channel and subchannels to have a first preselected distance between the base and cover that is greater than the width of the tapes. A second preselected distance between oppositely facing walls bordering the subchannels that is greater than the thickness of the tapes, and a third preselected distance between oppositely facing walls at the exit end that is greater than the thickness of the laminated tapes. A solder duct means mounted on the box for directing molten solder into the inner channel to flow from the exit end to the entrance end. The solder duct means having a slot extending therethrough and aligned with the exit end. A seal means mounted on the solder duct means adjacent the slot for minimizing solder escaping from the slot while solder coated tapes pass therefrom, and a wiper means mounted on the solder duct means and positioned from the seal means removes excess solder from tapes passing through the seal means.

    摘要: The solid-liquid diffusion process used to form triniobium tin superconductor is improved by oxidizing the tin coated niobium substrate with an oxide layer on the surface of the tin coat after tin dipping. The oxide layer can be added to the tin coat by passing the tin coated niobium substrate through an oxidizing chamber before the reaction anneal step, by adding oxygen to the reaction anneal furnace with argon or helium, by adding oxygen to the cooling tower immediately after the tin dipping process, or by controlling the exit temperature of the tin coated substrate from the tin dip in room atmosphere conditions.

    摘要: In a rolling loop motion picture apparatus, such as a projector or camera, the movie film is pressed against a film supporting surface disposed within a light path. In order to be cleaned, the film supporting surface is moved out of the light path to an inoperative position opposite a sheet of material formed of an inert polyurethane material to which particulate contaminants adhere. The sheet is moved into contact with the film supporting surface, whereby the particulate contaminants adhere to the sheet. Then the sheet is retracted from the film supporting surface, along with the particulate contaminants. The film is guided between fixed and movable guide surfaces. The movable guide surface is spring-biased downwardly against the top edge of the film and is constrained against horizontal movement.

    摘要: A method and apparatus for atomizing liquid metal are disclosed. A vessel supplies liquid metal through a pouring channel to an atomizing nozzle. A flow sensor provides at least one gas flow into the liquid metal, and determines a pressure difference from the gas flow. A processor determines the liquid metal flow rate through the nozzle from the pressure difference. A control adjusts the liquid metal flow rate in response to the determined liquid metal flow rate, and the liquid metal is atomized.

    摘要: A method of reducing "fall back" contamination caused by high intensity heating of metals is taught. Splatter, vapor droplets and particulate matter resulting from the high intensity heating is repelled to avoid return to the melt. An electric field is established above the heating zone to repel the vapor droplets and particles from at least one charged electrode disposed above the surface where high intensity heat is applied to a metal surface.

    摘要: The method and apparatus of this invention is related to measuring a flow rate of a liquid having a density .rho. from a vessel having an inner cavity and a pouring channel. A flow sensor introduces a first gas flow into the liquid in the cavity at a first position, the inner cavity having a cross-sectional area A.sub.1 at the first position, and a second gas flow into the liquid in the pouring channel at a second position, the pouring channel having a cross-sectional area A.sub.2 at the second position, there being a vertical distance z between the first and second positions. A transducer provides an output signal proportional to a pressure differential p.sub.1 -p.sub.2 between the first and second gas flows. A processor receives the output signal and determines the liquid flow rate m through the pouring channel according to the proportional relation ##EQU1## where g is gravity.
