Patent number: 6951372Abstract: The adaptive brake application and initial skid detection system allows rapid brake application and prevents deep initial skids. Brake pressure is compared with a predetermined threshold brake pressure. Wheel velocity error signals are also generated to indicated the difference between the wheel velocity and a reference velocity signal. A pressure bias modulator integrator responsive to brake pressure signals adjusts the wheel velocity error signals to provide an anti-skid control signal. The pressure bias modulator integrator can also be initialized to the value of the measured brake pressure when the wheel velocity error signals indicate the beginning of a skid. Brake pressure difference signals are generated to indicate the difference between brake pressure and a commanded brake pressure, and an adjusted brake pressure error signal is generated in response to the brake pressure difference signals.Type: GrantFiled: August 19, 2002Date of Patent: October 4, 2005Assignee: Hydro-Aire, Inc.Inventors: Bijan Salamat, Robert D.

Patent number: 6942733Abstract: A fluid sealing system is provided for use in a crystal puller for growing a monocrystalline ingot. The crystal puller has a housing, a fluid flow path contained in the housing, and a fluid passage through a wall of the housing for passage of fluid. The fluid sealing system includes a fluid connector head adapted for connection to the fluid passage and to the fluid flow path to establish fluid communication between the fluid flow path and the outside of the housing. The head has a port adapted for fluid communication with the fluid passage through the wall of the housing. First and second seals around the port are adapted for sealing engagement with the head. A space is defined generally between the first and second seals, and a leak detector is arranged to monitor the space for detecting fluid leakage past at least one of the seals.Type: GrantFiled: June 19, 2003Date of Patent: September 13, 2005Assignee: MEMC Electronics Materials, Inc.Inventors: Carl F. Cherko, Robert D. Cook

Patent number: 6935367Abstract: A fluid level control apparatus for selectively controlling the movement of liquid flowing out of a flotation cell is described. The fluid level control apparatus is significantly reduced in size in comparison with the flotation cell or cells to which it is connected which enables less expensive construction and reduced operating costs in terms of both the equipment and the plant as a whole. The fluid level control apparatus comprises a vessel having a valve positioned therein which includes a valve body structured with a curved surface which provides selective and finite control of fluid flowing through the vessel of the control apparatus. In one embodiment at least one of the inlet and outlet of the control apparatus exhibit a cross-sectional area taken transverse to the intended fluid flow therethrough having a substantially horizontal dimension which is greater than a substantially vertical dimension.Type: GrantFiled: September 3, 2002Date of Patent: August 30, 2005Assignee: GL&V Management Hungary KFT.Inventors: Robert D.

Patent number: 6639886Abstract: A apparatus and method for dissipating heat from the disk portion of a multimedia radio. The apparatus and method uses the Von Karman Viscous Pump Principle to strategically introduce holes in the housings and brackets of the multimedia radio to improve the air flow across at least one of the surfaces of an installed and operational disk. The amount, size, and configuration of these holes are a function of the type and size of disk used and the rotational speed of the disk in operation. This reduces the possibility of hot media and reduces the possibility of heat shutdown of disk components.Type: GrantFiled: July 14, 2000Date of Patent: October 28, 2003Assignee: Visteon Global Technologies, Inc.Inventors: Robert D.
