Abstract: An electrical connector system can comprise a first connector and a second connector. The first connector can include a first threaded coupling feature defining a first axis. The first connector can also include a first electrical contact with a first contact surface having an annular configuration centered on the first axis by a radius. The second connector can include a second threaded coupling feature defining a second axis. The second connector can also include a second electrical contact with a second contact surface offset from the second axis by the radius. The first and second threaded coupling features can be operable to engage one another to couple the first and second connectors to one another such that the first and second axes are aligned, thereby facilitating contact or separation of the first and second contact surfaces upon relative rotation of the first and second connectors.

Abstract: A lockable relative rotation device can comprise a first body including an outwardly extending inner flange having a first side, and a first interface feature associated with the first side of the inner flange. The lockable relative rotation device can also comprise a second body operable to rotate relative to the first body about an axis and to translate relative to the first body in first and second directions parallel to the axis. The second body can include an inwardly extending outer flange disposed proximate the first side of the inner flange, and a second interface feature associated with the outer flange. The first and second interface features can be operable to selectively engage and disengage one another upon relative translation of the first and second bodies in the first and second directions, respectively.

Adjacent tubes in the trough assembly are aligned with the plurality of entry and exit openings.

Abstract: A continuous galvanizing apparatus for rods and process therefor. The apparatus includes a liquid reservoir. A plurality of adjacent tubes each pass into, through, and out of the liquid reservoir. Each of the adjacent tubes has at least one opening within the liquid reservoir so the tubes are in fluid communication with the reservoir. A rod drive mechanism moves a plurality of adjacent rods into, through, and out of the plurality of adjacent tubes. A kettle is provided beneath both the liquid reservoir and beneath the tubes. At least one pump pumps liquid from the kettle to the liquid reservoir so that liquid is continuously cycled to the tubes.

Abstract: A power control apparatus can include a power circuit configured to transfer power to a load circuit. The apparatus can also include one or more environmental sensors configured to register environmental data including at least one of movement, hazardous gas, environmental temperature, environmental moisture, and collision data associated with the apparatus. The apparatus can also include a power controller circuit operatively connected to the one or more environmental sensors and the power circuit, the power controller circuit being configured to receive the environmental data from the one or more environmental sensors, determine whether the received environmental data exceeds a predetermined threshold, and in response to determining that the received environmental data exceeded a predetermined threshold, interrupting supply of power from the power circuit to the load circuit.

Abstract: An electrical cable connector assembly comprises an electronics connector fitting having a first coupling portion and a second coupling portion, and a connector body having a connection portion coupled to the second coupling portion of the electronics connector fitting. The connector body has a sleeve interface portion formed about an outer surface of the connector body. An elongate compliant sleeve has a connector interface portion coupled to the sleeve interface portion of the connector body to form a coupling interface having a keyed profile. The elongate compliant sleeve has an electrical cable channel configured to receive a portion of an electrical cable electrically coupleable to an electronics device, and configured to relieve strain on the electrical cable in at least one radial direction relative to a longitudinal central axis of the connector body.

Abstract: A safety electrical power connector can include a first connector body having a first electrical contact and an outer surface, and a second connector body that engages the first connector body in an axial direction. The second connector body can have a second electrical contact and an inner surface configured to slide relative to the outer surface of the first connector body in the axial direction during engagement of the first and second connector bodies. The outer surface and the inner surface can define a gap therebetween sufficient to establish an isolation enclosure that isolates a volume containing the first and second electrical contacts therein. The gap can be formed prior to electrical communication of the first and second electrical contacts thereby preventing an explosion due to arcing between the first and second electrical contacts.

Abstract: A cable drum transportation and handling apparatus for mounting, transporting and handling large cable drums includes a supporting structure, which supporting structure may be mounted on a truck or trailer. The apparatus includes stabilizers mounted to the supporting structure, a hydraulics control system and an operator station, a gravity drive having a drive wheel tire for turning the drum to spool cable in or out, and a hydraulic drive system for the gravity drive. An adjustable mechanism ensures firm connection between the tire and a cable drum, when a drum is mounted on the apparatus. A lever arm or bolt pattern puts more or less tension on the gravity drive, for engagement, by moving the drive up and down. Opposing hydraulically-operated lift arms pivotally mounted on an upper part of the supporting structure may be pivoted outwardly and rearwardly. The lift arms laterally close to grasp the drum.

Abstract: A tank for transporting fluids on a truck chassis includes a front wall, side walls, a back wall, a top, and a floor. Interior stairs extend from the floor to an opening in the top to allow stair access into the interior with integrated safety handrails on the fill port cover. Stair toe kicks act as internal transverse baffles to help control fluid motion and surging. The stairs also act as a structural stiffener between longitudinal baffles. Horizontal baffles assist in controlling fluid motion and surging. Formed baffles provide strength and stiffness. A baffle interlocking system improves joint integrity and aids manufacturing. Formed outer skins provide structural strength for the tank. Ports located in front and rear bulkheads may be used for tank ventilation or, depending on local safety codes, as secondary access points. Doors or other access openings may be located in the tank bulkheads to provide better interior access.

Abstract: A clamp for supporting an apparatus, such as a pump, a motor, or other mechanism to be lowered into a drill hole includes two coupling halves connected together using a bolts and nuts. Each half has a semicircular interior that forms a cylinder when two halves are connected to each other. Protrusions in the semi-circular interiors mate with indentations in the pump wall to support the pump. Chains or other devices attach to eyelet bolts or to a pivoting bail affixed on top of the coupling halves so that the clamp and the pump may be raised or lowered by external lifting apparatus.

Abstract: A truck body includes a front wall, side walls, and a floor. The floor has panels disposed at predetermined angles from the horizontal that, with the other parts of the body, form a payload volume within the body. The floor also includes a tail panel disposed at a lesser angle from the horizontal to facilitate the shedding of the payload when dumping, and further to maintain the center of mass of the payload in a generally forward position during dumping.
