  • Patent number: 7140481
    Abstract: A clutch piston amplifier assembly is provided for applying pressure to a clutch pack for engaging a first member and second member of an automatic transmission. The clutch piston amplifier assembly utilizes an amplifier piston which applies a secondary force to an apply piston for increasing the amount of apply force that can be obtained from the clutch assembly without increasing the diameter of the apply piston or the line pressure supplied to the piston assembly.

  • Publication number: 20050217962
    Abstract: A clutch assembly is provided including a first member and a second member rotatable relative to the first member. A clutch pack is provided for frictionally engaging the first and second members. A piston chamber is provided adjacent to the clutch pack, and a piston is disposed in the piston chamber and operable for applying axial pressure to the clutch pack. The piston includes first, second, and third seal portions integrally molded in place on the piston and engaging the piston chamber at spaced locations. The integrally molded first, second, and third seal portions reduce the number of components necessary for properly sealing the piston chamber and reduce the amount of labor required for assembly.

  • Patent number: 5632914
    Abstract: A cover for covering an air bag in a motor vehicle has a thin elastic plastic skin, a rigid substrate and an intermediate layer of soft plastic foam. The skin has a tear seam and the substrate includes a door that is impacted by the inflating air bag and presses outward against the foam layer and the skin to tear the foam layer and the tear seam and then swing outward with a torn section of the foam layer and skin to form an opening in the cover for deployment of the air bag into the passenger space in the vehicle. The tear seam in the skin is formed with extremely small laser machined holes that are not observable to a person of normal vision when viewed from a normal viewing distance in the passenger compartment by having a maximum hole size dimension at the outer side of the skin that does not exceed about 0.0005 inches.

  • Patent number: 5558909
    Abstract: A metallizing apparatus for vacuum-metallizing both recessed and non-recessed surfaces of relatively massive articles such as automotive wheels includes a vacuum chamber and a linear array of electron beam-type metal particle emitters. The emitter array is positioned in the chamber to thermally evaporate metal onto each article. A rack is supported within the chamber and rotates about a horizontal rack axis between two vertical end braces. Two or more identical articles are supported to rotate on the rack about respective second and third axes as the rack rotates about the horizontal rack axis. The articles both rotate around the rack axis and each simultaneously rotate around their respective second and third rotational axes while being held in the path of metal particles emanating from the emitters. The articles are mounted on the rack so that their respective second and third rotational axes are positioned at an angle to the rack axis. Adjustable pivot mechanisms allow an operator to vary these angles.
