Abstract: A fluid dispensing apparatus is disclosed. The apparatus includes a fluid container defining a fluid cavity. A manifold assembly is mounted over a container bunghole. A tube assembly including a fill tube extends into the fluid cavity. Keyed couplings are mounted on the manifold assembly. One of the couplings is in communication with the fill tube and another coupling is in communication with the cavity. A pressure relief valve is mounted adjacent the manifold assembly. Tamper evident assemblies are provided on the manifold assembly for determining if the fluid container has been opened.

Abstract: The invention pertains to a fitting consisting of a tubular body which may be readily installed over the end of a smooth wall conduit and removed therefrom and may be quickly connected to a standard unisex adapter mounted on the end of a hose line to place the conduit and hose line in fluid communication. The fitting includes a positive lock for attaching the fitting to the conduit and a flexible retainer is employed for safety purposes to resist "blow off".

Abstract: A seal for a fitting adapter for fluid couplings wherein a coupling probe is received within a recess within the other coupling half and the seal prevents the creation of subatmospheric pressures during withdrawal of the probe. The seal includes a lip or flapper valve component which establishes sealing during coupling pressurization, and permits atmospheric pressure to flow around the lip during coupling disconnection.

Abstract: The invention pertains to an automatic shut-off refueling nozzle particularly suitable for use with military vehicles employing a nozzle having a liquid level sensor operating a flow valve, the nozzle includes a lug plate attachable to the inlet of the tank receptacle being filled wherein once attached to the tank inlet the presence of an operator is not required during refueling. A diverger on the nozzle spout improves flow characteristics within the tank inlet to prevent premature release of the nozzle flow valve and the nozzle prevents contamination during refueling and prevents spillage of volatile fuels even though unattended. An embodiment of the invention utilizes a secondary control valve preventing fluid flow until the nozzle has been fully connected to the tank inlet.

Abstract: The invention relates to a self-aligning couling for connecting laboratory animal cages to a drinking water supply. A male coupling is attached to a grommet assembly at the back of the cage and a female coupling is assembled to a fluid supply manifold at the back of a shelf located so that when the cage is placed on the shelf and translated to the rear the male coupling will automatically conect to the female coupling and water supply. The grommet assembly allows the male coupling to be self-aligning in angular and radial directions to facilitate coupling.

Abstract: The invention pertains to a fueling nozzle vapor collecting apparatus attachable to a standard fuel dispensing nozzle spout. The apparatus includes a rigid plate connected to the spout having an annular resilient cup-shaped hood affixed to the plate periphery having a foam cushion defined on its outer edge for sealingly engaging the surface surrounding a fuel tank inlet. A collecting hose for the vapor is attached to a port defined in the plate for venting the vapor to a location remote from the nozzle, and a sight glass is adjustably positionable within a seal located in the plate providing visual observance of the fuel level.

Abstract: A coupling fitting consisting of male and female parts wherein connection is achieved merely by axially inserting the male into the female part. Latching is produced by a plurality of resilient fingers mounted on the female part engaging with an annular shoulder formed on the male part, and release of the fingers is achieved by an axially displaceable sleeve permanently mounted on the male part displaceable to a release position engaging the fingers and removing the fingers from the shoulder permitting the male part to be removed from the female part. The release sleeve may be of a configuration to discourage tampering and uncoupling, or may include a knob to facilitate manual actuation.
