An elevator car door opening and closing apparatus is taught having a clutch assembly carried by each car door for coupling with a landing door locking and unlocking assembly whereby the car and landing doors open and close simultaneously. The clutch assembly includes a four bar mechanical expanding and collapsing parallelogram linkage which engages, unlocks, and opens the landing door. Mechanical linkage is also attached to the parallelogram linkage whereby the elevator car doors may only be forced opened a limited amount if the car is stalled between landing sites.

A poppet valve assembly is provided for use on a fuel tanker truck which enables the trucks driver to determine whether fuel is flowing through the valve assembly and whether fuel is present in the valve assembly. When a threshold flow rate through the valve assembly is reached, fluid flows inside a flow channel. The flow channel has a fluid indicator and a flow indicator therein mounted in a sight glass. When fluid is flowing in the flow channel both indicators rise. When fluid is present but not flowing in the flow channel only the fluid indicator rises. The fluid and flow indicators, being different colors, may be easily seen at a distance.

A socket assembly is provided which is part of an overfill protection system for use on a bottom loading fuel tanker truck. The overfill protection system includes a plurality of sensors in the truck compartments which are electrically coupled via wires to the socket assembly. Due to wear, the outer socket of the socket assembly may need to be replaced. The present invention enables an operator to replace the worn socket without having to disconnect the wires from the socket assembly.

A poppet valve assembly is provided for use on a fuel tanker truck which enables the truck's driver to determine whether fuel is flowing through the valve assembly and whether fuel is present in the valve assembly. The valve assembly has a two part housing, one of the parts having a sight glass secured therein. The sight glass is visible through cutouts in the housing. When the poppet valve is opened, fluid flows through a flow channel in the valve assembly. The fluid, being different colors, may be easily seen through the sight glass from a distance.

A method of making a coupling assembly for use in a loading adapter of a gasoline tanker trailer. The coupling includes an aluminum coupling body and a wear resistant bronze sleeve. The wear resistant bronze sleeve provides a durable surface for receiving latches. The sleeve does not bond to the coupling body, but rather is constrained thereto by physical interference.

A "smart vent" valve is mounted on a liquid storage tank employed in the transportation of liquid. The valve prevents overpressurization of the tank due to increases in vapor pressure and prevents discharge of liquid through the valve in response to pressure surges caused by accidental overturning of the tank. A valve member is provided for a vent opening. Sealing engagement is maintained between the valve member and the vent opening during a finite period of valve member travel caused by an increase in pressure within the tank. The rate of valve member travel is limited by hydraulic system in which hydraulic fluid is forced through orifices from one chamber to another. The high levels of pressure surges do not have sufficient duration to displace the valve member a distance sufficient to move it to a position in which the vent opening is unsealed and liquid could escape therefrom.
