Patent number: 5007315Abstract: A servicer is described for supplying two cut-to-length strips of sidewall simultaneously to a tire building drum without handling by the tire builder, thereby eliminating any stretching of the sidewalls or distortion of the shape of the sidewalls which can happen when the sidewalls are physically handled by the tire builder. The servicer employs twin cassettes which contain two spools of spirally wound sidewall which is separated by a comparatively rigid, U-shaped protective liner.The servicer has an indexing table for moving twin cassettes from a standby position to a let-off position to a take-up position and, lastly, to a removal position where the cassette is removed for rewinding with new material.Type: GrantFiled: November 21, 1988Date of Patent: April 16, 1991Assignee: General Tire, Inc.Inventors: Joseph H. Alexander, Stanley L. Radcliffe, Martin N. Robertson, Eugene A. Bator, John E. Anderson

Patent number: 4726299Abstract: A method and apparatus for controlling movement of a vehicle through a network is disclosed. The network has a plurality of stations interconnected by a plurality of path segments. A plurality of branch points connect the path segments and require a vehicle approaching a branch point to be directed in either a first or second direction. Line-defining parameters are provided for each of the branch points and define a network-dividing line which divides the plurality of stations into a first set which are attainable by a vehicle being directed in a first direction and a second set attainable by a vehicle being directed in a second direction. Coordinates of a destination station are associated with a vehicle. As the vehicle approaches a branch point, the coordinates of the destination station are compared to the line-defining parameters of the approaching branch point and the destination station is determined to be in either the first set or the second set.Type: GrantFiled: February 20, 1986Date of Patent: February 23, 1988Assignee: Regents of the University of MinnesotaInventor: John E.

Patent number: 4313723Abstract: In a carbon black manufacturing process in which a carbon black dryer is utilized to produce a product carbon black having a specified dryness, method and apparatus is provided for controlling the flow of fuel to the carbon blackdryer so as to insure that the dryness of the carbon black product will meet predetermined specifications. Feedforward, predictive control of the flow rate of the fuel to the carbon black dryer is utilized to compensate for changes in the flow rate of wet carbon black or for changes in the moisture content of the wet carbon black. In this manner, the dryness of the carbon black product is maintained at a predetermined specification even though process variations may occur.Type: GrantFiled: November 6, 1980Date of Patent: February 2, 1982Assignee: Phillips Petroleum CompanyInventors: Robert H.

Patent number: 4166770Abstract: A control system for a fractionation column which separates a feed into a heavy bottoms product, which is used as fuel for a plant, and into a light overhead product, which is used in a process, is disclosed. The fractionation column is controlled in such a manner that sufficient bottoms product is supplied to meet the plant fuel requirements while maintaining a desired distillation temperature for the overhead product. The flow rate of fuel oil to the reboiler furnace associated with the fractionation column and the flow rate of the external reflux to the fractionation column are controlled in such a manner that the objectives of supplying sufficient bottoms product to meet plant fuel requirements and supplying an overhead product having a desired distillation temperature are met while still minimizing the external reflux flow rate and the flow rate of the fuel oil to the reboiler furnace to increase fuel economy.Type: GrantFiled: May 22, 1978Date of Patent: September 4, 1979Assignee: Phillips Petroleum CompanyInventors: John E. Anderson, Gary L. Funk

Patent number: 4144997Abstract: The control of the flow rates of multiple fuel streams to furnace burners is accomplished by manipulating the flow rate of each fuel stream in response to a calculation of the heat duty which must be supplied by the respective fuel stream. Where the supply of a preferred fuel is variable, the flow rate of the other less preferred fuel stream is varied in response to changes in available supply of the preferred fuel to insure that sufficient fuel is available to the burners to maintain a required process temperature.Type: GrantFiled: October 12, 1977Date of Patent: March 20, 1979Assignee: Phillips Petroleum CompanyInventors: John E. Anderson, Robert H. Kallenberger

Patent number: 4127798Abstract: A system for operating gas discharge lamps at high frequency from a high voltage supply, typically 115 V AC with a 160 watt, 25,000 Hz output. The system provides efficient conversion, having the capability of driving any number of lamps up to maximum wattage, inherent open-cirucit and short circuit protection, and higher efficacy from the lamps. Filament power may or may not be used. Filament power is not necessary under conditions when the lamps are forced into a glow discharge to charge each cycle through the use of a tuned resonant circuit. An unsaturated inverter provides fast cut-off times. Dimming capabilities may be provided.Type: GrantFiled: November 4, 1977Date of Patent: November 28, 1978Inventor: John E. Anderson
