Abstract: A pump can include a plunger and a barrel, at one stroke extent flow being substantially restricted between the plunger and the barrel at spaced apart positions and a plunger interior passage in filtered communication with a fluid chamber between the positions, and at an opposite stroke extent the fluid chamber being in communication with the standing valve. A method can include displacing a plunger in one direction, thereby receiving filtered liquid into a fluid chamber, and b) displacing the plunger in an opposite direction, thereby transferring the liquid to a barrel interior passage. A system can include an actuator that reciprocates a rod string, and a pump including a plunger with a traveling valve, a barrel with a standing valve, and a filter that filters liquid which flows from a tubing string to a compression chamber disposed between the traveling valve and the standing valve.

Abstract: When securing a watthour meter to a meter box base, a meter sealing ring is typically used. A quick-fastening watthour meter retaining member is provided, in certain embodiment of the present invention, to reduce installation time and generally comprises a circular band, a connector housing member, and a receiver housing member. The connector housing member and a receiver housing member are preferably mounted to the terminus ends of the circular band. A portion of the connector housing member, comprising locking protrusions or “teeth”, is adapted to engage, with a ratchet-type action, in one example embodiment, and fasten into the receiver housing member, which contains, a pre-installed “padlock type” frangible sealing device in an example embodiment. Removal of the ring is accomplished by simply cutting, in one embodiment, and removing the frangible sealing device and allowing the housings to disengage from each other.

Abstract: The present invention relates to an apparatus and method for securing a box cover to a watthour meter socket box. In certain embodiments, the apparatus has a clamping member that fits over a wall of a meter box, and a lock housing that locks to the clamping member after a box cover has been installed, thereby securing the cover to the box in a manner such that the box cover cannot be installed unless the clamping member has been installed correctly. In various other embodiments, the clamping member consists of a clamp disposed between a clamp actuating member and a fastening shelf In various other embodiments, the clamp includes a stopping member for indicating when the clamp actuating member is actuated into a fully secured position. Other embodiments relate to a locking bracket and a lock housing wherein the locking bracket generally comprises a clamping member and a fastening lever that attaches to a wall of a meter box base.

Abstract: An apparatus for connecting a plurality of structures, such as ends of a sealing ring, with each end defining an aperture therein and with the ring being adapted to mount a meter to a meter box structure. The apparatus comprises a locking pin with a distal end adapted to be insertable through each of the apertures of the first and second ends of the ring. The locking pin comprises a head member having at least an engageable end and a fracturable member. The locking pin further comprises a shaft portion having the distal end. The apparatus further comprises a lock housing adapted to retain at least a part of the shaft portion such that the first and second ends of the ring are connected between the head member of the locking pin and the lock housing. The head member has an outer surface adapted to receive at least two opposing forces, the at least two opposing forces being of sufficient magnitude to break the fracturable member.
