Patent number: 4505221Abstract: Apparatus and method for asymmetrically coating a tape-shaped carrier body with crystallized silicon for further processing into solar cells. In an exemplary embodiment a carrier body in the form of a graphite mesh is to be drawn through a guide channel leading from the floor of a melt vat and is moistened by the melt. The silicon is caused to crystallize above the melt vat because of a temperature gradient generated at right angles relative to the path of the coated carrier body. The temperature gradient can, for example, be produced by means of single-sided heating, or by a plate-shaped body extending from the melt parallel to the carrier body, or by guide lips with upper boundaries exhibiting different heights and widths. The method and apparatus serve for the continuous manufacture of silicon tapes for solar cells.Type: GrantFiled: July 11, 1983Date of Patent: March 19, 1985Assignee: Siemens AktiengesellschaftInventors: Richard Falckenberg, Helmut Foell, Josef Grabmaier

The coated wire is then radiation cured conventionally.Type: GrantFiled: September 20, 1979Date of Patent: March 31, 1981Assignee: W. R. Grace & Co.Inventors: Harold A. Kloczewski, Cheryl N.

Patent number: 4245584Abstract: Disclosure is made of an apparatus for applying paste upon blank strips for cermet electrodes of alkaline storage batteries. The backing strip is advanced by a drive through a bin filled with the paste. This bin is made in the form of two autonomous reservoirs having in their respective lower portions, in the walls thereof facing each other, ports with edges through which the paste can leave the reservoirs. The upper edges of these ports define, upon said reservoirs having closed upon the backing strip, an application nozzle having centering lugs made on the edges of the ports, to center the backing strip with respect to the application nozzle.Type: GrantFiled: February 9, 1979Date of Patent: January 20, 1981Inventors: Ivan A. Kolosov, Nikolai V. Kuryshev

Patent number: 4242368Abstract: An improved method for manufacturing a composite metal wire including a core metal wire having extruded therearound a coating metal layer which is different in material from the core metal wire, includes feeding the coating metal into a narrow passageway which is defined between a circumferential groove formed on the outer edge of a rotary wheel and a close fitting surface of a fixed shoe block, carrying the coating metal towards an outlet end of the passageway by frictional drag with the surface of the passageway in accordance with the rotation of the wheel, and passing a core metal wire harder in material than the coating metal through a covering chamber of a larger cross sectional area which is provided with a die and a nipple at the front and rear portions, respectively, whereby the core metal wire is covered with the coating metal in the covering chamber so that a predetermined construction of a composite metal wire is extruded through the die.Type: GrantFiled: April 25, 1978Date of Patent: December 30, 1980Assignee: Hitachi Cable, Ltd.Inventors: Masahiro Nagai, Yasuhiko Miyake

Patent number: 4217852Abstract: Apparatus for manufacturing a composite metal wire including a core metal wire having extruded therearound a coating metal layer which is different in material from the core metal wire. The coating metal is fed into a narrow passageway which is defined between a circumferential groove formed on the outer edge of a rotary wheel and a close fitting surface of a fixed shoe block, the cross-sectional area therebetween decreasing for half the distance between entry and discharge and thereafter increasing until discharge. The coating material is carried towards an outlet end of the passageway by frictional drag with the surface of the passageway in accordance with the rotation of the wheel.Type: GrantFiled: December 4, 1978Date of Patent: August 19, 1980Assignee: Hitachi Cable Ltd.Inventors: Masahiro Nagai, Yasuhiko Miyake

Patent number: 4218202Abstract: Apparatus for forming a remote controlled cable having two conducting wires separated by a central element including a tank for containing fusible insulating material through which the conductors are passed as they are drawn through a gauging die. Guide means are employed to retain separation of the two conductors and includes a conical or convergent section adjacent the gauging die to maintain the spaced apart relationship of the conductors and a rubbing contact of the conductors on opposite sides of the die member. The resultant sub-assembly of the two conductors and the intermediate spacing support is then passed to subsequent means for enclosure within a plurality of parallel reinforcing and lapping yarns and enclosing coating.Type: GrantFiled: July 7, 1978Date of Patent: August 19, 1980Assignee: Chavonoz SAInventor: Pierre Seguin

Patent number: 4208200Abstract: Disclosed is an optical waveguide coating system having means for cooling the hot filament prior to the time that the filament enters the coating apparatus. The cooling means comprises an elongated container through which the filament passes. A coolant jacket, which surrounds the container, lowers the temperature of the filament cooling liquid in the container.Type: GrantFiled: May 8, 1978Date of Patent: June 17, 1980Assignee: Corning Glass WorksInventors: Stewart A. Claypoole, Merrill Lynn, Roger A. Miller

Patent number: 4204496Abstract: A steel-pipe coating process and an apparatus therefor, in which molten resin is extruded through a cross-head die connected to an extruder, into a tubular shape, in a manner to cover or coat the surface of a steel pipe. In this apparatus, a resin outlet in the extruder is communicated through the medium of a resin guide member with a resin inlet of the cross head die. The extruder is secured to a fixed frame, while the cross head die is supported by the fixed frame in a reciprocating manner through the medium of a reciprocating drive member within a given stroke in the direction of the steel pipe being fed. Thus, when the cross head die is reciprocated by means of the reciprocating drive member, the relative speed of the steel pipe being fed to the cross head die being reciprocated may be intermittently varied, whereby the amount of resin being extruded through a cylindrical outlet of the cross head die around the surface of the steel pipe may be intermittently varied.Type: GrantFiled: August 5, 1977Date of Patent: May 27, 1980Assignee: Kobe Steel, Ltd.Inventors: Yoshio Ikegami, Tadashi Kohge, Masakatsu Kawahara, Hirofumi Kimura

Patent number: 4202530Abstract: A flexible feeder tube with a weakened longitudinal side wall is coupled at one end by a nozzle with an underground conduit while the remaining end of the feeder tube is located aboveground and joined with a lubricating collar that is split. A supply of cable has a plain end and an end equipped with connectors joined to the conductors of the cable. The plain end of the cable is joined with a pull-line that is fed from the conduit through the flexible feeder tube. The plain end of the cable is then drawn into the feeder tube while lubricant is applied to the sheathing of the cable. Pulling of the cable through the conduit is terminated before the end with the connector members contacts the feeder tube. The lubricating collar is split and held together by fasteners which are loosened so that the collar can be removed from the cable and then the feeder tube is removed from the cable by severing the feeder tube along the weakened longitudinal side wall.Type: GrantFiled: December 5, 1978Date of Patent: May 13, 1980Inventor: Allen C. Conti

Patent number: RE31115Abstract: The disclosure is that of an invention directed to a horizontal padder and extractor for circular knit fabric tubes and includes a pair of squeeze rolls disposed with their axes in the same horizontal plane, thus defining an upwardly open nip for retaining a puddle of impregnating liquid. A safety guard is pivotally mounted over the squeeze rolls and is operably connected to an electrical interlock to deactivate the machine whenever the safety guard is not in proper position. A steaming station is provided ahead of the padder and extractor and a horizontal orienting spreader feeds the spread fabric tube to the padder at a tangent to the upper surface of the front squeeze roll thereof.Type: GrantFiled: August 18, 1980Date of Patent: January 4, 1983Inventor: Frank Catallo
