Abstract: A bristle ring diffuser for diffusing UV light is described herein. In one example, the radiation diffuser cone comprises a base and a plurality of bristles. The base has an interface which is coupleable to an object having an ultraviolet (UV) light source. The base also has an aperture which aligns with the UV light source when the interface is coupled to the UV light source. The plurality of bristles is arranged about the aperture and extend from the base. The plurality of bristles is opaque to UV light and is angled away from a central axis of the aperture.

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.

Abstract: Load control interlocks are disclosed and described. The interlocks provide for coupling a power circuit to one or more load circuits once the one or more load circuits and the power circuit are both coupled to the interlock, and disconnects the power circuit from the one or more load circuits if the one or more load circuits or the power circuit are uncoupled form the interlock or an electrical connection between the power circuit and the one or more load circuits is broken.

Abstract: A continuous galvanizing apparatus for multiple rods. The apparatus includes a kettle for heating and retaining a liquid therein with at least a portion of the kettle having an open top. A trough assembly retains liquid therein. The trough assembly is arranged above the kettle open top above the liquid level, with the trough assembly having at least one lower chamber within the kettle below a level of the liquid in the kettle. A pump in the lower chamber draws liquid from the kettle to the trough assembly. A plurality of entry openings are provided in the trough assembly along with a plurality of exit openings opposed to and aligned with the entry openings. 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: An apparatus includes: a storage unit configured to provide a device design; a control unit configured to analyze the device design for a multi-cycle exception, generate a multi-cycle exception profile, and generate a checker based on the multi-cycle exception profile for a test bench for a simulation version of the device design.

Abstract: A seal section for connecting a downhole motor and pump used to remove fluids from an oil well comprising a plurality of balance chambers which are vertically stacked and fluidly interconnected in a serial manner such that a fluid path between the well and the motor extends through a series of balance chambers. Each balance chamber is comprised of two concentric, open ended tubes disposed within a tubular casing member and the tubes of each balance chamber are mounted on different ones of seal heads which are spaced vertically along the seal section to delimit the ends of the balance chambers. Each seal head intermediate the seal heads disposed at upper and lower ends of the seal section is provided with one upperwardly extending tube and one downwardly extending tube such that any selected number of balance chambers can be formed by selecting the number of intermediate seal heads to be incorporated into the seal section.
