Patent number: 5490785Abstract: A water-tight splice connector made from an existing connector, including a first housing and a plurality of pins mounted in means for splicing the pins together located in the housing. A first seal member is located at one end of the housing behind the splicing means and pins. A retainer member engages the housing behind the seal member to protect and secure the seal member in place in the housing. A terminal locking member is insertable in the end of the housing opposite the end receiving seal member to lock and align the pins in place within the housing. A second seal member is located in a second housing containing female terminals for receiving the pins in the first housing. An interfacial seal member is located between the first housing and second housing to seal both housings from outside moisture and water. In the case where the first and second housings are used to connect the wires of two harnesses together, the splicing means is made smaller to permit the wires to bypass the splicing means.Type: GrantFiled: October 28, 1994Date of Patent: February 13, 1996Assignee: Alcoa Fujikura LimitedInventors: David A.

Patent number: 5470005Abstract: A method of sensing tension changes in a sheet of material in a processing line, the material having a mass flow balance in the processing line. The method includes using a dancer roll for engaging the sheet and an actuator for mechanically and momentarily introducing changes in the mass flow balance of the sheet. A sensor is provided for detecting sheet tension at a location near that at which the sheet engages the dancer roll and for producing signals indicative of sheet tension. An algorithm is provided for processing the signals in a manner that determines the dynamic relationship between tension variations near the location of the roll and at other locations in the processing line. The signal processing is effective to identify the presence of the magnification of variations in sheet tension so that the causes of such magnification can be identified.Type: GrantFiled: June 8, 1994Date of Patent: November 28, 1995Assignee: Aluminum Company of AmericaInventors: Eugene O.

Patent number: 5453110Abstract: A method of gas fluxing molten aluminum with at least two, relatively small diameter upper and lower rotatable dispersers located in the molten aluminum and mounted on a shaft. Fluxing gas is added to the molten aluminum beneath each of the rotatable dispersers at a substantial rate of gas flow while rotating the dispersers at a substantial rpm in the molten aluminum. The dispersers directly shear gas bubbles that form in the molten aluminum as the fluxing gas is directed into the molten aluminum beneath each of the dispersers. The direct shearing of the gas bubbles maintains a high surface area between the bubbles and molten aluminum to effect efficient removal of impurities in the molten aluminum.Type: GrantFiled: January 26, 1995Date of Patent: September 26, 1995Assignee: Aluminum Company of AmericaInventors: Ho Yu, Michael Scherbak

Patent number: 5391430Abstract: A product for heating a load at different rates using microwave radiation provided at a substantially constant power level. The product may include a polymer matrix alone or in combination with a metal substrate, with the polymer matrix located on the surface of the metal substrate that does not contact the load and is thus disposed to the incident microwave radiation. The matrix includes dielectric and magnetic components in amounts that enable at least initial absorption of the incident radiation and thus initial thermalization of the radiation within the matrix. The matrix is designed to change its rate of thermalization and the rate at which it conducts thermalized radiation to the substrate and load after a predetermined time of exposure to the radiation at a predetermined temperature of the matrix.Type: GrantFiled: June 23, 1992Date of Patent: February 21, 1995Assignee: Aluminum Company of AmericaInventors: Thomas J.

Patent number: 5250364Abstract: A metal sheet for making rigid container products, and a method of making the sheet. The sheet has a fissureless surface that retains minute amounts of lubricant in generally uniformly spaced apart elongated micron-sized depressions, the depressions providing a quasi-isotropic surface texture which, in turn, provides a substantially uniform distribution of friction at the interface of the surfaces of the sheet and a tool employed to form the container products. The depressions, in addition, provide the product surface with a high degree of specular reflection of light and thus a bright surface having a high level of distinctness of an image reflected from the surface.Type: GrantFiled: February 3, 1992Date of Patent: October 5, 1993Assignee: Aluminum Company of AmericaInventors: Louis G.

Patent number: 5233852Abstract: A method providing a rolling mill with compensation for changes occurring in rolling parameters that result from changes occurring in mill speed. The rolling parameters are under control of actuators that are connected to receive control reference voltages from electrical controllers. The method includes the step of generating a compensation function that describes the actuator movement required to maintain a rolling parameter at a desired level as a function of mill speed. This compensation function is used during mill speed changes to calculate a compensation value change for each actuator, a change that is required to maintain the parameter at the desired level. The compensation value change is added to a current level of the compensation value to provide a new, updated compensation value. The updated value is converted to a voltage for control of the actuator, and the voltage is added to the reference voltage of an associated electrical controller to provide a total voltage reference for the actuator.Type: GrantFiled: April 15, 1992Date of Patent: August 10, 1993Assignee: Aluminum Company of AmericaInventor: Ralf Starke
