Patent number: 4434837Abstract: A process and apparatus for forming a semi-solid thixotropic alloy slurry and preferably a rheocasting therefrom. Molten metal in a mold is cooled under controlled conditions while it is mixed under the influence of a moving magnetic field. A non-zero, magnetic field is provided across the full cross section of the mold and over the entire solidification zone. This results in a magnetomotive stirring force of sufficient magnitude to provide mixing of the molten metal to form the slurry. Preferably, a two pole induction motor stator is used to generate the magnetic field.Type: GrantFiled: February 24, 1983Date of Patent: March 6, 1984Assignee: International Telephone and Telegraph CorporationInventors: Joseph Winter, Jonathan A.

Patent number: 4414832Abstract: An apparatus and process for operating a rolling mill having at least two rolls rotating at different speeds to produce a continuous strip material having a substantially constant final thickness comprises a mechanism for controlling the magnitude of the compressive force between the rolls in response to the ratio of the incoming strip speed to the outgoing strip speed. A mechanism is provided for comparing the ratio of the strip speeds to a ratio of the roll speeds and for adjusting the compressive force magnitude until the two speed ratios are substantially equal. In this manner, the amount of off-stage strip material produced during mill start-up is reduced and process stability and gage control during steady state operation is enhanced.Type: GrantFiled: September 11, 1981Date of Patent: November 15, 1983Assignee: Olin CorporationInventors: William L.

Patent number: 4286744Abstract: A process is disclosed for joining narrow width thin gage metal or alloy strip end to end to form an elongated coil. The trailing end of a first strip segment and the leading end of a second strip segment are cut so as to match when placed in a butting relationship and to establish a joint between the strips. A preselected gap is established between the butting ends and a braze material is inserted in the gap. After heating to braze the strip segments together, the brazed joint is hammered to reduce the joint geometry to that of the parent metal strip segments.Type: GrantFiled: November 21, 1979Date of Patent: September 1, 1981Assignee: Olin CorporationInventors: Damian V.
