Abstract: A method and device for rotational disconnection a nozzle from a valve body, to include transferring torque applied to an input adapter, through a gear system, to a rotational, self-centering chuck, with a plurality of jaws to secure a nozzle threadedly secured within a valve body, and an anchor tower extending from the base of the tool in the same direction as the tool that is positioned for nozzle release, so that the anchor tower may provide rotational fixation of the valve body while torque is applied to the nozzle, along with a manner to employ coordinatedly sized and positioned gears, which in combination multiply the leverage force or torque input into the tool for application to the rotational disconnection effort.

Abstract: A tool and method for moving racked tubulars, such as pipe and casing joints on pipe racks at oil and gas well sites, wherein the tool comprises a disk assembly with a handle section. The disk assembly comprising at least one disk with a surface to slideably interface the interior surface of the pipe section during lateral movement of the pipe section.

Abstract: A walking foot for a drilling rig comprising a foot plate attacheable to a drilling rig by an travel plate, capable of functionally bearing a load in excess a quarter of the weight of a drilling rig, comprising a planar roller array wherein a plurality of load rollers with parallel rotational axes are dispersed both laterally and longitudinally within the plane, so as to fractionalize a weight applied perpendicular to the plane, and thereby promote longitudinal motion of the roller array in a direction perpendicular to the plurality of roller rotational axes.

Abstract: An extreme load creeper interface comprising a planar roller array wherein a plurality of extreme load rollers with parallel rotational axes are dispersed both laterally and longitudinally within the plane, so as to fractionalize a weight applied perpendicular to the plane, and thereby promote longitudinal motion of the roller array in a direction perpendicular to the plurality of roller rotational axes.

Abstract: A sports training aide is described which is configured to limit the vertical sight of a player during basketball, soccer, golf, and hockey training, encouraging the player to focus on the other players during dribbling, rather than the ball at the player's feet or hands. The sports training aide is an apparatus device employing a head brace strap, a waist brace strap, and a brace connector strap which function together in order to prevent the downward vertical movement of the head of the player during training The apparatus is preferably affixed to the forehead and waist of the player with at least one adjustment buckle. The apparatus is preferably equipped with a quick release clasp, and a foam padded head brace strap for comfort during use.

Abstract: A plurality of thin metal film battery cells (12) are stacked together to form a stick (14). An array of the sticks (14) are carried in a case (16) and are connected in series to provide a high voltage output at the case terminals (20, 22). A switching arrangement managed by a control unit (52) is used to test and recharge the battery cells. If one of the sticks (14) is defective, it is bypassed and replaced with a replacement stick in order to maintain the desired output voltage.
