  • Patent number: 6250659
    Abstract: A vehicle variable height adjustment strut assembly 10 adjusts height of a vehicle 100 and replaces a vehicle strut by being mounted at a vehicle strut mount location. Assembly 10 has a vehicle variable height adjustment system 15, a height adjustment air bag 40, and a shock absorber 50. System 15 includes an air bag strut tower coupler 20 and an air bag control arm coupler 30. Air bag strut tower coupler 20 is mounted to a vehicle strut tower 60, and air bag control arm coupler 30 is coupled to a vehicle control arm 70. Air bag 40 is coupled between the air bag strut tower coupler 20 and the air bag control arm coupler 30. Air bag 40 is inflated and deflated to respectively raise and lower the vehicle 100. An air pressure control system 110 is coupled to the height adjustment air bag(s) 40, and the air pressure control system 110 controls pressure levels of the air bag(s) 40.

  • Patent number: 6250663
    Abstract: A spit-frame, heavy truck, suspension system for trucks that haul trailers made of three moveably interlocked rigid frames referred to as the front frame, rear frame, and interconnecting frame. The front frame supports the cab, engine, and transmission. The rear primary frame supports the drive axle and fifth wheel. The rear end of the interconnecting frame is pivotally mounted to the rear frame whereby the rear frame may rotate about a transverse axis. The front end of the interconnecting frame is mounted to the front frame in a manner that permits the interconnecting frame to rotate and pivot along its longitudinal axis relative to the front frame. Hydraulic cylinders are used to dampen vibrations and oscillations within this spit-frame structure.

  • Patent number: 6197110
    Abstract: A liquid phase deposition method of mass producing substantially uniform silicon dioxide films on wafers by forming wafer sets from at least four wafers. The wafer sets are placed in a slotted polytetrafluroethylene polymer boat wherein a proper and short distance between the front surface of a wafer and another surface is created. Finally, a substantially uniform silicon dioxide film is deposited on the wafer surfaces by contacting the wafer sets with an aqueous supersaturated silicon dioxide solution comprising a mixture of hydrofluosilicic acid and boric acid.

  • Patent number: 6167361
    Abstract: The present invention includes a method and computer program for determining possible configurations of a racing vehicle Four-Link assembly. A user of the computer program is prompted for measurements of the Four-Link assembly bracket apertures relative to the garage floor. The measurements are entered into the computer program to produce reference points for the vehicle. The computer program then permits a calculation of lines comprised of the relevant Four-Link assembly bracket apertures and an interpolation of points on each line representing a possible Four-Link configuration. The computer program then renders either a video display and/or a printout of the possible Four-Link configurations and the intersect points of the lines created by the interpolated lines representing Four-Link configurations.

  • Patent number: 6102459
    Abstract: The present invention is a vacuum valve assembly that creates vacuum on demand. The assembly has a body with a fluid inlet port, a fluid outlet port, a fluid flow channel extending between the fluid inlet port and the fluid outlet port, a vacuum port, a low pressure channel extending between the vacuum port and the fluid flow channel, a sensing member receiving channel, the sensing member receiving channel extending between the fluid flow channel and the low pressure channel, and a flow occlusion chamber that intersects the fluid flow channel. There is a sensing member with a fluid flow regulation portion and a sensing portion. The sensing portion is adapted to be movably received by the sensing member receiving channel. The sensing member is movable from a closed position to an open position.
