Abstract: An inline winder is provided for taking-up a rapidly advancing filament, especially a glassy alloy filament of indefinite length at constant speed directly from a high speed continuous forming process without tension isolation. The winder is inherently load-following and thus eliminates the need for any complex feedback control system. The winder comprises a winding reel rotatively driven by a synchronous-hysteresis electrical motor and selection means for independently adjusting voltage and frequency input to the motor. The method of using the winder comprises preadjusting the frequency input to initially synchronize winder and filament speeds and preadjusting voltage input to select winding torque and initial winding tension. A transfer device is also disclosed wherein winding is transferred uninterruptedly from a wound, rotating reel to an empty, rotating wheel.

Abstract: Structurally defined continuous metal strips are formed by forcing molten metal onto the surface of a moving chill body under pressure through a slotted nozzle located in close proximity to the surface of the chill body. The surface of the chill body (chill surface) whereon casting of the strips takes place has a contoured surface, i.e. it is provided with structurally defined protruberances and/or indentations, which are faithfully replicated by the formed strip, the thickness of the strip being substantially uniform throughout, regardless of whether it replicates a level area of the chill surface or a raised or indented area.

Abstract: Continuous metal strips are formed by forcing molten metal onto the surface of a moving chill body under pressure through a slotted nozzle located in close proximity to the surface of the chill body. Critical selection of nozzle dimensions, velocity of movement of the chill body surface, and gap between nozzle and chill body surface permits production of continuous polycrystalline metal strip at high speeds, and of amorphous metal strips having high isotropic strengths, heretofore unobtainable dimensions, and other isotropic physical properties such as magnetizability.

Abstract: The method of applying ohmic contacts to a semiconductor, such as a silicon body or wafer used in solar cells, by the use of arc plasma spraying, and solar cells resulting therefrom.

Abstract: Defined shapes of thin metallic sheet are continuously formed by forcing molten metal onto the surface of a moving chill body under pressure through a slotted nozzle located in close proximity to the surface of the chill body. The surface of the chill body whereon the shaped parts are formed is provided with raised or lowered domains corresponding in outline to that of the desired defined shape. As the metal is cast, as a thin sheet against the chill surface, discontinuities arise in the sheet at the walls of the raised or lowered domains defining the desired shape so that sheet product of defined shape is obtained, as if punched out from a continuous strip of the metal.

Abstract: Strips of amorphous metal containing embedded particulate matter and method for making it. Strips of amorphous metal containing embedded particles of abrasive material are useful for working the surfaces of solid articles by abrasion for forming or surface improvement. The method of making such strips involves forcing molten metal of a glass-forming alloy containing admixed particulate matter onto the surface of a moving chill body under pressure through a slotted nozzle located in close proximity to the surface of the chill body.

Abstract: Method and apparatus is provided for the inline string-up, in automatic fashion, of a rapidly advancing filament, particularly a glassy alloy strip, from a high speed continuous casting operation onto a rotating winding wheel. The leading segment of the advancing filament is passed into the nip of two counterrotating brush rollers 15 having a peripheral velocity exceeding that of the advancing filament to produce a sliding frictional tensioning of the filament. The brush rollers and engaged filament are then moved over the rotating winding wheel 28 to lay a segment of the advancing filament onto the rotating winding surface. A cut-and-grip device 8 associated with the winder is then actuated to cut the filament at the winding surface and to secure the filament onto the winder, whereupon winding of the advancing filament proceeds.
