Abstract: A portable apparatus includes an electrical component that provides, in use, a variable power demand; energy storage; a power source; and control circuitry. The control circuitry is configurable between a first configuration in which the power source outputs power to the electrical component and to the energy storage via the electrical component; and a second configuration in which the power source outputs power to the electrical component and the energy storage outputs power to the electrical component.

Abstract: A non-transitory computer readable storage medium has instructions executed by a processor to ingest source data tables received from a network connected source data machine. A pivot frame is derived from the source data tables. The pivot frame has an index column with index column values representing each unique combination of records in the source data tables, pivot dimension columns forming a deterministic matrix where each row of the deterministic matrix represents a unique combination of records in the source data tables, and a value column with individual values assigned to corresponding index column values. A definition of a desired pivot table is received from a network connected client machine. Pivot values are retrieved from the pivot frame that fulfill the definition of the desired pivot table to form a pivot table with unique pivot table row and column values. Index column values are associated with the unique pivot table row and column values.

Abstract: A lock mandrel is described herein. The lock mandrel includes an upper connector and a lower connector. The upper connector includes locking keys configured to attach the lock mandrel to a landing nipple on a tubing within a hydrocarbon well. The upper connector also includes a spring-loaded locking collar configured to prevent the locking keys from disengaging from the landing nipple by pressing radially against the locking keys from the inside when in a seated position, and allow the locking keys to disengage from the landing nipple by retracting away from the locking keys when in an unseated position. The lower connector includes a tool adaptor configured to attach a downhole tool to the lock mandrel.

Abstract: A trunnion seal assembly for joining a stationary inlet/outlet box of a ball tube mill to a rotational interior of the ball tube mill includes an outer ring component configured to be mounted to an outer wall of the stationary inlet/outlet box. An inner ring component is joined to the outer ring component substantially concentrically with the outer ring component. A flexible pad seal is configured to be joined to the outer wall of the stationary inlet/outlet box proximate outer ring component. The pad seal includes a first annular sealing surface. A mill head extension ring configured to be joined to a rotational mill head is located proximate to and substantially concentric with the inner ring component. The mill head extension includes a second annular sealing surface sealingly engaged with the first annular sealing surface of the flexible pad seal.

Abstract: A guide bushing for a tensioning rod in a vertical pulverizer includes a bushing body having a substantially cylindrical interior bushing surface configured and adapted to moveably engage a tensioning rod of a vertical pulverizer. The bushing body is divided circumferentially about the bushing surface into a plurality of sections joined together. The sections are configured and adapted to separate from one another for installation and removal of the bushing body about a tensioning rod of a vertical pulverizer.

Abstract: A head section for a rotary cutting device includes a body portion that includes a blade passage defined between a blade entrance opening and a blade exit opening. A blade fastening mechanism is positioned in the blade passage and includes a blade engaging member. The blade engaging member is biased by a biasing mechanism to extend across the blade passage at a blade install position. The blade engaging member is movable against the bias to clear the blade passage. A blade having a mount aperture proximate an insertion end thereof is secured to the body portion when the mount aperture occupies the blade mount position and the blade engaging member extends through the mount aperture. The blade can be installed in and removed from the head section without tools, simply by advancing the blade through the blade passage.

Abstract: An illustrative gripping accessory or thumb is adapted for use with a machine having a tool, for example, a backhoe bucket attached to an extendable or non-extendable arm of a dipper stick. The accessory or thumb can be releasably attached to the machine and includes a pair of grip members that can be pivotably coupled to the distal pivot pin connecting the bucket and extendable arm and a grip linkage coupled between each grip member and the intermediate pivot coupling the extendable arm and the rotatable linkage coupled to the bucket rotation cylinder. Thus the use of the gripping accessory with a bucket requires no welding or other permanent modification of the machine and can be stowed or removed when not in use.
