Abstract: A starter ring for a pump packing assembly is disclosed. The assembly comprises an annular portion adjacent to an opening of a housing cylindrical surface. An axially outwardly extending portion opposite the opening and engaged with the housing cylindrical surface. Layers of a fabric reinforced elastomeric material covering the radially inwardly extending annular portion and the axially outwardly extending portion. A male adapter pocket is positioned at one side of the starter ring and configured to displace the volume of the starter ring and to generate a wiper force for initiating a wiping effect on the adjacent position of the at least one resembling shape of annular sealing ring. The male adapter pocket allows pressure forces from the reciprocating plunger to intensify the wiping effect of the starter ring, and exclude proppants from coming in contact with the at least one resembling shape of annular sealing.

Abstract: The invention is a set of reduction gears constructed to aid the installation or removal of a packing nut or similar equipment part onto or from an oil field pump. A first gear is integrated onto a packing nut or other threaded part to a piece of oil field equipment. The first gear is placed in rotational contact with a second gear rotatably mounted on the surface of a fluid end. The second gear is a reduction gear which a worker can turn to thread the first gear of the packing nut. The invention includes a pawl set against the first gear prevent unwanted loosening of the packing nut during operations.

Abstract: Embodiments of the present invention are directed to systems and methods for alerting a golfer when he or she moves his or her head during a swing or stroke. According to an exemplary embodiment, a golf training aid comprises a movement detection mechanism and an alerting system. The training aid can comprise, for example, a support structure, such as a tube, and a weighed object, such as a ball. The weighted objet is located on or in the support structure, and the support structure is coupled to the golfer's headwear, such as a hat or visor. The weighted object is initially settled in a receiving portion of the support structure, but displaces when the golfer moves his head. The displacement alerts the golfer to the head movement, allowing the golfer to reduce or eliminate such movement from his or her golf game.

Abstract: A drop ball for use in wellbore activities, such as wellbores in oil and gas drilling, completion and/or production activities comprising a generally spherical body, the spherical body carrying at least one marker, which contains and/or can determine at least one parameter related to the drop ball, the wellbore and/or activities being conducted in the wellbore.

Abstract: A swashplate style pump uses a dual location cluster bearing of consistent configuration for use in each of two positions in the pump. In one location the dual location cluster bearing will interface with pistons and the swashplate cam. In a second location the dual position cluster bearing will interface with the non-camming side of the swashplate and the back plate of the pump. The dual position cluster bearing can be used in either and both positions with equal facility.

Abstract: In a swashplate style pump a cam follower that interfaces the pump pistons and the swashplate cam is a ring of material. This ring of material will be provided with a bearing surface and a piston contacting surface having the piston contacting surface provided with piston receiving elements.
