A recessed floor fitting includes a poke-through housing, a divider assembly, and a feeder plate. The poke-through housing has a base and an outer wall with an open top that defines an interior chamber. The base includes a central aperture, a first perimeter aperture, and a second perimeter aperture. The divider assembly separates the interior chamber into a center portion, a first portion, and a second portion. The center portion is in communication with the center aperture. The first and second portions are in communication with the respective first and second perimeter apertures. The feeder plate is connected to the base, and has a mounting flange and a conduit extending from the mounting flange.

Electric vehicle charging station

A tamper resistant electrical receptacle for use with 20 A receptacles. A pair of pivoting shutter and trap doors biased in the same direction use a cam and cam follower that moves laterally a distance sufficient to allow passage of the perpendicular portion of a neutral blade of a 20 A electrical plug when simultaneous insertion of electrical plug tines overcome the spring bias of the springs to allow the tines to access the devices hot and neutral electrical contacts. Absent simultaneous insertion, the shutter and trap doors cannot operate in tandem to provide the tines passage to the electrical contacts.

Tamper resistant receptacle with cam feature

A tamper resistant electrical receptacle comprising a slide housing disposed beneath the hot and neutral blade openings in the receptacle. The slide housing includes a neutral slide body and a hot slide body having slide pads and tabs for reducing friction when the bodies slide against each other as the spring bias of the bodies in the slide housing is overcome by simultaneous insertion of the tines of an electrical plug contact ramp surfaces and camming past the slide bodies causing them to slide against each other and spreading a gap area a distance sufficient for receiving the lateral neutral prong of a 20 A electrical plug.

A liquid ring pump is provided that includes an annular housing having an inner surface forming a housing cavity. The annular housing is filled with an operating fluid during operation of the pump. The operating fluid forms an eccentric liquid ring in the annular housing during operation of the pump. A rotor is disposed in the housing cavity and includes a plurality of rotor blades. A shaft extends into the annular housing into the housing cavity. The plurality of rotor blades extend radially outward from the shaft toward the inner surface of the annular housing. A liner formed from a corrosion resistant material is disposed substantially flush with at least a portion of the annular housing inner surface opposite a plurality of rotor blade ends.
