Abstract: A centering tool assembly helps centrally position a casing in a tubing using a baseplate, actuator, support tube, power source, and reaction studs. The baseplate is positioned on an outside edge of the tubing. The actuator is either preinstalled on the baseplate or installed after positioning on the tubing's outside edge. The support tube vertically adjusts the actuator. The power source activates the actuator which provides a force against the casing, moving the casing into the central position. Reaction studs or counteracting members help stabilize the centering tool assembly during this positioning. The centering tool assembly may be used to either pull or push the casing into the desired position. Additionally, a method for centering a casing into a central or desired position in a tubing involves placing a baseplate on the edge of the casing. An actuator is installed on the baseplate and vertically adjusted via a support tube.

Abstract: An apparatus and method for restraining movement of insulation during construction of a metal frame building. The apparatus having a plate with an opening, a hook member received by the opening, and a restraint holder. The hook member engages a girt to hold the apparatus in position. A restraint member extends from the holder to reduce movement of insulation, generally draped from an upper portion of a building frame, caused by wind prior to attachment of siding on a metal frame building.

Abstract: A dispensing system for mixing at least first and second components and dispensing an expanding foam is disclosed. The system includes separate vessels, each containing a foam component, and a dispensing apparatus. The dispensing apparatus includes a cartridge assembly mounted on a body assembly. The cartridge assembly includes a mix chamber and first and second ports, each for supplying a foam component to the mix chamber. A pair of adjusting valves is mounted to the cartridge assembly with each valve operable to adjust the flow of each foam component to the mix chamber. A pair of hoses connects the vessels to the cartridge assembly. Each adjusting valve is a variable orifice device in the cartridge assembly having the capability of varying the flow area of the port. The present invention also includes a method for adjustably controlling, at the dispensing apparatus, the flow of each of the first and second components to the mixing chamber to alter their ratio therein.

Abstract: A downhole tool bearing assembly is provided which utilizes a secondary annular threaded locknut and a compression ring in order to take up tolerance stack-up and to provide supplemental preload through a bearing housing assembly, thus helping to ensure against accidental disassembly during operation. The bearing housing assembly is comprised of a prepackaged subassembly of thrust bearings, sleeves and, optionally, "BELLEVILLE"-type disk springs which can be quickly and easily installed onto a downhole tool drive shaft or other similar apparatus by maintenance personnel having a minimum of training. The bearing housing assembly is designed such that reconfiguration involves little more than removal and reinstallation in the opposite orientation, thereby overcoming the need to reconfigure the bearing assembly one bearing at a time.

Abstract: A storage apparatus for use with pool cues and cone chalk. The storage apparatus includes a housing having upper and lower ends and a substantially vertical surface between the upper and lower ends. An upper member is attached to the upper end of the housing. The upper member has a plurality of openings extending therethrough. An intermediate member is attached to the housing below the upper member. The intermediate member has a plurality of openings extending therethrough corresponding to the plurality of openings in the upper member. The plurality of openings in the intermediate members are substantially vertically positioned below the plurality of openings in the upper member. A rod is attached to the upper member for locating the cone chalk. The openings in the upper and intermediate members are sized to receive a pool cue.
