Abstract: A controller for self-refilling resuscitation enclosures has a pair of arms pivotable between open and closed positions, an inside strap fixed to both arms, and an outside strap fixed to one arm. The outer strap can be releasably coupled at any one of a series of locations along the other arm, to selectively limit the amount of resuscitation bag recovery and thereby adjustably control the expansion or recovery volume of the enclosure. The straps, along with portions of the arm inside surfaces, maintain a contiguous wrapping engagement about the resuscitation enclosure throughout its compression and expansion, to positively secure the enclosure. The arms afford a mechanical advantage to reduce user fatigue, and provide for the tactile sensing of lung compliance during resuscitation.

Abstract: A fuel filler pipe assembly is provided which controls the release of fuel vapors from a vehicle fuel tank so as to limit the amount of fuel vapor released into the atmosphere. The assembly includes an outer tube which is partitioned into two conduits--one for carrying fuel to the vehicle's fuel tank and the other for carrying fuel vapors to an onboard vapor capture device. Passage of fuel vapors to the vapor capture device is controlled by a valve which itself is controlled by the attachment and detachment of a fuel filler cap to the assembly such that attachment of the cap causes the valve to close while detachment causes it to open. In certain preferred embodiments, the assembly includes a second valve for preventing the passage of substantial quantities of liquid fuel to the vapor capture device.

Abstract: A package that contains component parts of a carburetor tune-up kit is formed in a box-like configuration with a plastic overwrap that protects the component parts contained in the package from the environment outside the plastic.

Abstract: In a ceiling structure, wood structural components, such as wood joists or trusses, have wood shield pieces interposed between them and a sheet-like ceiling which is carried by the structural components. The shield pieces protect the structural components in the event of a fire below, in that they must be consumed by the fire before the structural components are jeopardized, and this requires additional time which extends the fire rating of the ceiling.

Abstract: An in-tank, fuel pump assembly for fuel-injected engines is provided which includes a reservoir having a supply port for supplying fuel to the engine and a return port for receiving fuel returning from the engine. Within the reservoir are (1) an electrically-operated, high pressure pump, (2) a jet pump located at the bottom of the reservoir for entraining fuel into the reservoir, (3) a valve associated with the return port, and (4) a valve associated with the supply port. The output of the high pressure pump is routed to the jet pump and to the two valves whereby when the high pressure pump is not operating, both valves are closed, and when the high pressure pump is operating, both valves are open and the jet pump entrains fuel into the reservoir. The jet pump is sized to entrain more fuel into the reservoir than leaves the reservoir through the supply port thus producing a net flow of fuel from the bottom to the top of the reservoir.

Abstract: A multi-chambered conduit insert includes at least two spaced-apart longitudinally extending substantially parallel first and second chambers. The cross-sectional configuration of each of the chambers is defined by generally parallel inner and outer side walls joined at one edge thereof by a base wall and joined in an opposite edge thereof by a top wall. A hinge portion connects adjacent edges of the inner walls and the base walls of the chambers together. Opposite ends of the inner walls are spaced farther apart than the adjacent ends of the inner walls in order to expose the exterior surfaces of the inner walls to a cooling medium during the manufacturing process. In one embodiment, the hinge portion can function as a living hinge.

Abstract: The present invention relates to a method for utilizing a unique multi-chambered conduit insert for converting a single chambered conduit into a multi-chambered conduit. In particular, the conduit insert includes a plurality of cooperating longitudinally extending walls defining a plurality of parallel spaced apart coextensive chambers. The outer wall of each chamber which is adjacent the inner supporting surface of the single chambered conduit has a configuration wherein, if the outer wall contacts the inner conduit surface when the conduit insert is inserted within the conduit, such contact is line-to-line contact. This construction results in minimal contact of the insert with the interior wall of the existing conduit and enables the multi-chambered conduit insert to be fed into the existing conduit with the expenditure of minimal energy.
