Abstract: A power tong continuously rotates tubulars for spinning and torquing threaded connections. Continuous rotation is achieved through a rotating jaw having grippers that grip the tubular and continuously rotate with it. Hydraulic and electrical power necessary for actuating the grippers is generated on board. A serpentine belt system turns the motors of the on-board hydraulic power unit and electric generators to supply the grippers with hydraulic and electrical power. The serpentine belt system is driven by a secondary drive mounted on a fixed frame. The rotating jaw is rotatably mounted to the fixed frame and driven during continuous three hundred and sixty degrees of rotation by a primary drive, mounted on the fixed frame. A fixed jaw is also mounted to the frame. Tubular grippers on the fixed jaw grip a first side of a tubular joint. The grippers on the rotating jaw grip the opposite second side of the tubular joint. High torque low-rotational speed applied to the rotating jaw torques the joint.

Abstract: Fuel cells, and renewable-semi-liquid fuel mixtures, useful as anode materials, for said fuel cells are disclosed. The fuels are comprised in part of materials intercalated with hydrogen, alkali metals, or alkali metal hydrides, dispersed in liquid carriers. The chemical energy generated by the reaction of the fuel mixtures with oxygen, or an oxygen carrier such as air, water, or hydrogen peroxide, can be converted into electrical energy in fuel cells. Once converted, the by-products of the reaction may be collected and those components that where chemically modified in the reaction can be renewed by conversion or re-intercalation of hydrogen, alkali metals, or alkali metal hydrides.
Abstract: An apparatus for handling pipes in a derrick and racking the pipes on a pipe racking assembly mounted on the derrick is provided to improve the stability of transferring pipes during a round trip operation. The apparatus includes a rotatable gate assembly mounted on the pipe racking assembly. The rotatable gate assembly includes a collar rotatably mounted to a first end of a shaft and an arm pivotably and rotatably mounted on a second end of the shaft. The collar defines a gate for securing an upper portion of the pipe stand. A first securing means mounted to a second end of the arm secures the mid-portion of the pipe stand and a second securing means mounted to the first securing means secures the lower portion of the pipe stand. After the arm secures the pipe stand from the derrick, a drive mechanism mounted to the shaft rotates the rotatable gate assembly such that the arm may rack the pipe on the pipe racking assembly.

The shelves pull out on the slides, away from the standards. The distance between the pair of slides may be adjusted. A pair of opposed facing tangs are mounted on the base end of each mounting bracket. Each pair of tangs are adjustable to clamp into slots in the corresponding standard.
Abstract: An apparatus for securing wire connectors includes a rotatable cylindrical member defining at least one chamber configured to store at least one wire connector. A frame supporting the rotatable cylindrical member is detachably mountable on a drill. A dispensing housing mounted on the frame receives the wire connector from the chamber and dispenses the wire connector though an outlet after a rotator twistably engages and secures the wires onto the wire connector. The rotator is selectively rotatable by actuating the drill when the end of a wire is inserted into the wire connector, the wire connector thereby engaging the rotator.
Abstract: A shopping list organizer includes a rigid substantially planar member sized to support a shopping list when the shopping list is mounted thereon. A clamp is provided for releasably mounting the shopping list on a first surface of the planar member. Magnets are mounted on a second side of the planar member, opposite the first side, for releasably mounting the planar member on a flat substrate. At least one clip is hingedly mounted to the second side of the planar member for rotation about the hinge between a closed position substantially flush against the second side of the planar member and an open position substantially orthogonal to the second side of the planar member. In the open position, the clip is disposed for releasably mounting onto an elongate handle.

Abstract: A portable smoking room having a flexible enclosure defining a room detachably mounted on a frame is provided. A duct is detachably mounted to the frame for transporting smoke laden air within the flexible enclosure outside of the flexible enclosure. A fan detachably mounted to the duct creates negative pressure within the flexible enclosure such that smoke laden air within said flexible enclosure may be drawn out though the duct and ambient air from outside may be drawn in through a plurality of air intake apertures in the flexible enclosure. The frame of the portable smoking room may be disassembled when the enclosure and the duct are detached from the frame such that the flexible enclosure, the frame, the fan, and the duct may be transported and reassembled at another location.
Abstract: An apparatus for identifying, tracking and handling lumber to be cut-in-two includes a scanner and optimizer to scan the length of a board and to compare the scanned board to predetermined criteria so as to identify a board which, optimally, would be cut into two pieces along its length. An identification device applies a detectable indicator to the board. A transfer transfers in a downstream direction, the board from the scanner to the identification device, and from the identification device to a lug-loader loading device adjacent and immediately upstream of a lug loader. A detector cooperates with the lug-loader loading device so as to detect the detectable indicator on the board and to delay the loading of the lug loader following loading of the board into a lug space so that an immediately subsequent lug space behind and upstream of the board is left empty so as to receive a portion of the board cut from the board once the board is cut-in-two in a downstream trimmer or other sawing device.

A plurality of threaded bores are formed in spaced array around the base flange. Rigid elongate threaded members are threadably mountable into the threaded bores so as to be selectively threadably adjustable in the threaded bores and so as to protrude downwardly from the base flange into engagement, beneath the manhole frame, with a top surface of the support ring when the manhole frame is mounted on the support ring. The threaded members are threadably adjustable in the threaded bores to elevate or to tilt the manhole frame relative to the support ring.
Abstract: A search and rescue beacon includes a main transmitter transmitting a Cospas-Sarsat signal at a main frequency and an auxiliary homing transmitter transmitting a homing signal at a homing frequency close to the main frequency. Advantageously both the Cospas-Sarsat signal and the homing signal are generated by a single synthesizer switching between a main Cospas-Sarsat burst transmission and a continuous homing frequency transmission of the homing signal. The Cospas-Sarsat signal is advantageously transmitted at a higher power than the homing signal. The single synthesizer may use a single amplifier chain. The single synthesizer and amplifier chain may use a single antenna.
