  • Publication number: 20070175514
    Abstract: A vent structure at least partially defining a passageway between the inside of a fuel storage tank and the outside atmosphere includes a separator membrane. The separator membrane is positioned within the vent structure configured to block liquid fuel in the storage tank from reaching the outside atmosphere through the passageway. The separator membrane is permeable by air. The vent structure may be in the form of a cap or a remote vent, or it may be provided substantially within the fuel storage tank. The vent structure may be provided as part of a fuel evaporative emissions system for a vehicle or motor-driven power equipment.

  • Publication number: 20070170187
    Abstract: A method of assembling selected modular ratchet cap assemblies. In one aspect, the method includes the acts of providing identical threaded portions, providing identical cover portions, providing a first vent module, providing a second vent module different from the first vent module, selecting the first vent module and coupling together the first vent module with one of the identical threaded portions and one of the identical cover portions to form a first cap assembly, and selecting the second vent module and coupling together the second vent module with another one of the identical threaded portions and another one of the identical cover portions to form a second cap assembly. In other aspects, the method includes assembling first and second cap assemblies with identical cover portions and threaded portions, but having different pawl members providing different cap-installing torque limits.

  • Publication number: 20070169524
    Abstract: A cap for selective attachment with a threaded opening includes an outer cover and an inner portion, the inner portion lying at least partially within the outer cover and having threads engageable with the threaded opening and a set of circumferentially-spaced teeth arranged to selectively receive torque from manual rotation of the outer cover. A slider in constant driving engagement with the outer cover is selectively engageable with the teeth of the inner portion to transmit torque from the outer cover to the inner portion. An actuator is provided to actuate the slider into and out of engagement with the teeth of the inner portion. A lock is provided accessible from outside the outer cover and being coupled to the actuator. A locked state of the cap is one in which the slider is removed from engagement with the teeth of the inner portion by the lock and actuator and an unlocked state of the cap is one in which the slider is engaged with the teeth of the inner portion.

  • Publication number: 20070164031
    Abstract: A fuel cap operable to close an opening of a fuel tank. The fuel cap includes an outer shell having a protrusion and a shell locking member. The fuel cap includes a detection mechanism for sensing a level of fuel within the tank. The fuel cap further includes an assembly component engageable with the outer shell to support the detection mechanism on the outer shell. The assembly component defines a groove operable to receive the protrusion. Additionally, the assembly component includes a component locking member. The outer shell and the assembly component are engageable with one another by a relative axial movement followed by a relative rotational movement about an axis. Once engaged, the outer shell and the assembly component are fixed against disengagement by engagement of the shell locking member and the component locking member.

  • Patent number: 6974556
    Abstract: A co-injection nozzle pin (20) having downstream and upstream ends. The nozzle pin has therein a central bore (30) including an upstream end (32) adapted to communicate with a first material and a downstream end (34) exiting at the downstream end of the pin. The nozzle pin also has an outer surface (36) including a first portion (38) having a diameter D1, a second portion (40) having a diameter D2, wherein D2 is less than D1 and the first portion is rearward of the second portion. The pin further includes a channel (46) spiralling around the outer surface and being adapted to communicate with a second material. The channel (46) includes a first segment (52) defined in the first portion (38) of the outer surface and increasing in depth as it travels in a downstream direction and a second segment (54) defined in the second portion (40) of the outer surface and decreasing in depth as it travels in a downstream direction.

  • Patent number: 6964748
    Abstract: The invention provides a method of co-injection molding. The method includes mixing a plastic inner material and an endothermic-blowing agent to form a core mixture. A plastic outer material is injected from a first injection unit into a co-injection manifold to create a flow of outer material therethrough. The core mixture is injected from a second injection unit into the co-injection manifold to create a flow of core mixture therethrough. The flow of the outer material and the flow of the core mixture are then controlled through the co-injection manifold and into a mold cavity. The core mixture expands as heat is provided for the endothermic-blowing agent to absorb.

  • Publication number: 20040204693
    Abstract: A drainage device and a method for draining a liner-type medical suction apparatus and a rigid-walled container. The drainage device preferably includes a swingarm, a drainhead, and a suction source. The drainhead is positioned to be in fluid communication with the liner-type suction canister or the rigid-walled canister. The swingarm rotates to activate the suction source and inverts the liner-type suction canister or rigid-walled canister. The contents of the canister drain to a sewer system. The method includes the acts of placing the canister on the drainage device, coupling the drainhead to the canister, and activating the suction source.
