Patent number: 9415628Abstract: Application of carbon fiber reinforced polymer structures to metal vehicle wheels is effective in reducing the mass of the wheel while retaining suitable stiffness in the wheel structure. For maximum effect the reinforced polymer structure and the metal wheel must operate cooperatively. Because of the wide range of operating temperatures experienced by wheels and the large difference in coefficient of thermal expansion between metals and carbon fiber reinforced composites attachment of the polymer structure to the wheel by adhesive alone is problematical. However a wheel with an effective and durable reinforcement may be fabricated by confining, through mechanical interference, the reinforced polymer in a cavity in or on the spoke and by preheating the wheel before curing the polymer.Type: GrantFiled: May 11, 2012Date of Patent: August 16, 2016Assignee: GM Global Technology Operations LLCInventors: Hamid G. Kia, Michael J. Irwin

Patent number: 4117473Abstract: A horizontally oriented curve is produced on a raster type cathode ray tube display by storing curve data words in a memory and placing a series of dots on the cathode ray tube screen with each dot being at a height dictated by the value of the respective data word and at a horizontal position dependent on the order in which the respective data word is received. A dot counter provides an output signal for writing the curve data words into the address locations of the memory in the order in which the curve data words are received. A horizontal raster position counter provides a read address signal to the memory for each possible dot position in a horizontal scan. A comparator circuit compares each curve data word read out of the memory with a signal representative of the vertical position of the current horizontal scan and produces a video enable signal to produce a dot on the cathode ray tube screen when the compared signals are equal.Type: GrantFiled: January 25, 1977Date of Patent: September 26, 1978Assignee: Phillips Petroleum CompanyInventors: Charles C. Habeger, Jr., Michael J. Irwin
