  • Patent number: 9291270
    Abstract: A fluid seal of the present invention is disposed between an outer surface, i.e. engine block or any other part that requires application of the assembly and a rotatable member, such as, for example a shaft, wherein the seal circumscribes the shaft and lubricated the shaft and the same rotates around the axis. The seal present a cross section with plurality of channels that allow maximum expose of the seal to a salt bath thereby improving curing process and physical characteristics of the seal. A method of forming such fluid seal is disclosed in the present application.
    Type: Grant

  • Patent number: 8900494
    Abstract: An apparatus of the present invention presents a housing for engaging a mold device that includes a top plate having a top mold and a bottom plate having a bottom mold. The top plate presents side edges presenting a plurality of male elements extending therefrom. A top portion of the housing presents a safety and locking device (the device) to secure the top plate. The device presents several plates movable relative one another to secure the top plate. In case of a power outage, an actuator cooperably connected with the device prevents a shaft, connected to one of the plates, to move back to its idle position thereby locking the top plate within the device to prevent disengagement of the top plate from the device.

  • Patent number: 5928676
    Abstract: A fluid seal including a casing unit and an elastomeric lip body portion. Frustoconical air and oil side surfaces of the lip body meet at an inner diameter portion to form a fluid seal band contacting an associated shaft in use. A continuous, circumferentially extending garter spring is embedded in the seal lip body. An axially inner surface of the lip body is defined in part by plural spaced apart ribs and the remainder is defined by pockets having portions lying closely adjacent the radially and axially innermost portions of the garter spring. In the free state of said seal, the garter spring exerts a radially inwardly directed preload force so as to resist radial expansion of said seal. The spring also resists dimensional shrinkage of the seal band and the remainder of the seal body.
