Abstract: A flangeless fluid end comprising a fluid end body releasably attached to a connect plate. The connect plate is attached to a power source using stay rods. The flow bores of the fluid end are sealed without threading a retainer nut into the walls of each bore. Instead, the flow bores are sealed by bolting a retainer to the fluid end body. Plungers to drive fluid through the fluid end body are installed within removable stuffing box sleeves. These sleeves are maintained within the plunger bores by the bolted retainers. A number of features, including the location of seals within bore walls and carbide inserts within valve structures, aid in reducing or transferring wear.

Abstract: A fluid end for use with a power end. The fluid end comprises a plurality of fluid end sections positioned adjacent one another. Each section includes a single horizontally positioned bore. A plunger is installed within the bore and includes a fluid passageway. Low-pressure fluid enters the bore through the plunger and high-pressure fluid exits the fluid end through an outlet valve installed within the bore. The intake of low-pressure fluid within the fluid end section is regulated by an inlet valve installed within the plunger. Low pressure fluid enters the plunger through an inlet component attached to both the plunger and an inlet manifold.

Abstract: A power end assembly includes a crankshaft section, a crosshead section, and a connector section coupled together by one, two, or more sets of stay rods. The power end may include one or more support plates that are coupled to the crankshaft section and/or crosshead section. The crosshead section includes a plurality of individual crosshead frames. The connector section may include a plurality of individual connector plates or may be a unitary connector plate. The power end is configured to be coupled to a fluid end assembly by coupling the fluid end assembly to the connector plates.

Abstract: A fluid end assembly comprising a housing having multiple conduits formed therein. A tubular sleeve is installed within one of the conduits and is configured to house a plurality of packing seals. A seal is installed within a groove formed in the walls of the housing surrounding the tubular sleeve such that the seal engages an outer surface of the tubular sleeve.

Abstract: An apparatus for providing a target for a projectile comprises an elongate member extending between first and second ends, sized to span a playing surface. The apparatus further comprises first and second support legs extending from the first and second ends of the elongate member, each of the first and second support legs having a length selected to position the elongate member above and outside of a possible path of the projectile and a plurality of lights located on the elongate member selectable by a user to provide a visual target for a user. After the elongate member is positioned above and outside a possible path of the projectile a desired path for the projectile is selected and one of a plurality of lights on the elongate member to provide a visual target for a user expected to produce the desired path in the projectile is illuminated.

Abstract: A portable cooking station device is disclosed that allows users to cook food outside, over a fire, and supports large quantities of food and multiple pots and pans at the same time. The cooking station device comprises a base unit, a pair of vertical poles, and a horizontal bar secured between the pair of vertical poles for retaining cooking equipment. The base unit is configured to be placed directly over a fire pit. The pair of vertical poles are secured to the opposing sides of the base unit, and can comprise hooks for retaining cooking equipment. The horizontal bar can comprise S-shaped hooks for hanging cooking equipment. A rotisserie bar can be secured between the pair of vertical poles, below the horizontal bar, and a grate can be axially attached to one of the vertical poles to allow it to swivel out across the fire pit when in use.

Abstract: An optical module includes a base and a plurality of cooling fins mounted to the back surface of a printed wiring board used to support a number of opto-electronic devices. To optimize heat removal; the fins are mounted on the back surface in alignment with the opto-electronic devices mounted on the front surface. The module also includes a number of fiber-optic management features which are mounted on the wiring board or materially integrated with the base and cooling fins. By combining fiber-optic management features with a heat sink, on the opposite side of board-mounted opto-electronic components, the optical module achieves increased packaging density and functionality on a per volume basis compared with its conventional counterparts.

Abstract: The present invention relates to optical connectors for use in circuit modules in which the reduction of electromagnetic interference is an objective. In particular, the cable connector of the present invention provides an EMI shielded connector housing for mounting and sealing to a module faceplate and a cover plate that seals the remaining open portions of the housing and provides for access to the inside of the assembled connector. At least one cable terminal is included within the connector and provides for an external cable connection axis between approximately 15° and 75° from a normal of said module faceplate.

Abstract: Retarding a fire condition of a telecommunications component mounted on a module to be inserted into a telecommunications box is provided. The module may have a planar surface having a first side and a second side generally opposed to the first side. A ventilator provides a cross air flow generally in a direction from the first side to the second side. A first opening in the telecommunications box in an area adjacent of the first side of the planar surface forms a substantial portion of the cross air flow emanating from the first side. A second opening in the telecommunications box arranged in an area adjacent to the second side of the planar surface exhausts the cross flow air, such that the cross flow air sub-stantially retards the fire condition. An air flow guide is provided to simulate an air resistance of a module.

Abstract: A fiber-optic cable guide includes first and second guide walls, one or more base support elements for connecting the guide walls, and a number of securing elements which extend from the guide walls along a top portion thereof. Each securing member preferably has a length which is shorter than the spacing between the guide walls. This difference in length substantially corresponds to the diameter of a fiber-optic cable. A fastener may be included on a bottom surface of one or more of the guide walls for attaching the guide to a mounting surface, which may be a printed circuit board. Furthermore, the guide walls may be conformed to traverse any desired path along the board.
