  • Patent number: 6221306
    Abstract: A readily replaceable pin-in-sleeve device (A, B) for gas-assisted injection molding is used with a two-part mold to form an injection molded product from a plastic material. A sleeve (10) has a threaded exterior surface that is shaped to be received in a socket (130) of a mold member (210) opening into a mold cavity. A longitudinally extending bore (20) extends through the sleeve. The bore has a first portion (22) adjacent the cavity, and a second, larger diameter portion (24), spaced from the cavity. A pin (40) extends through the sleeve and has a forward section and an enlarged base, which are received in the bore first and second portions, respectively. A tortuous path for an injection fluid is defined between the pin and the bore to inhibit transport of plastic material into the device when the injection fluid is vented from the mold cavity. A filter 60 positioned in the bore, behind the pin, filters traces of plastic material from the vented injection fluid.

  • Patent number: 6149540
    Abstract: A continuously variable transmission (CVT) system for use on snowmobiles, ATV's and similar vehicles. The CVT includes a rotatable drive clutch connected to an input shaft (the input shaft being connectable to an engine), and a roller clutch carried on the input shaft. The CVT also includes a rotatable driven clutch connected to an output shaft, the driven clutch having a laterally stationary sheave and a laterally movable sheave that is normally biased toward the stationary sheave. An endless flexible drive belt is disposed about the drive and driven clutches. The clutches and drive belt are configured so that when the engine is idling the belt firmly engages a drive surface of the roller clutch that is connected to the drive clutch.

  • Patent number: 5970791
    Abstract: An improved rotary fluid meter is provided having expansion chambers for conditioning pressure pulses that may occur in the flow of fluids. The pressure pulses, which inhibit the meter's ability to accurately measure, may originate from within a metering device or from without it. The pressure pulses may be generated upstream of the meter. Fluid flows into the meter through a fluid flow conduit. At least one flow conditioning chamber which is of such a volume and a shape as to enable it to substantially dampen pressure pulses so as to improve the accuracy of the rotary meter is provided along the fluid flow conduit.

  • Patent number: 5950302
    Abstract: A improved stator apparatus for use in the ignition system of an internal combustion engine. The stator apparatus comprises a magnetically permeable core having a coil housing mounted to a leg portion thereof. A coil assembly including a voltage transformer is maintained in the coil housing. The various coils of the coil assembly are mounted about a central chimney member of the housing coaxial with the portion of the core extending therethrough. A circuit grounding member is electrically connected between the voltage transformer and the core by frictional contact therebetween. The circuit grounding member is constructed of a generally flat conductive piece having a longitudinal ridge defined along a portion of its length. In exemplary constructions, the longitudinal ridge extends along side a portion of the core and is biased into frictional contact therewith. The ridge facilitates assembly of the stator apparatus as well as enhancing electrical connection of the grounding member with the core.
