Abstract: A foldable-unfoldable bowling caddy has two spaced apart, parallel, generally vertically extending support legs mounted on wheels. A series of spaced apart flat forward racks rotatable to and from a folded position aligned with the two parallel legs to and from an unfolded horizontal position are attached to the two parallel legs. A third leg is pivotally connected to the two parallel legs and is movable to and from a folded position adjacent the two parallel legs to and from an angular position that forms a tripod with the two parallel legs. A rear rack is also connected to the two parallel legs and is rotatable to and from a folded position extending along the plane of the two parallel legs to and from an unfolded horizontally extending position. The third leg is releasably pinned to the rear rack when both are in their unfolded positions. A swivel ball is attached to the lower end of the third leg. Each rack contains seat openings for seating bowling balls.

Abstract: Two types of corner couplings together with horizontally extending and vertically extending beams form a multi-cornered paneled frame structure. One coupling connects, with suitable connectors, horizontally and inwardly extending panels to the horizontally extending beams and the other coupling connects, with suitable connectors, vertically extending panels to said horizontally extending beams and to the vertically extending beams. Other suitable connectors secure the two types of couplings to each other.

Abstract: Method and apparatus for generating seismic energy in offshore areas includes energy propagating means for directing energy downwardly vertically into an earth formation. A carrier contains an elongated rigid coupler means that extends from the carrier at the water level to the seat floor. A base plate may be connected to the lower end of the coupler means. The coupler means may be a section of pipe. Driving means on the carrier drives the coupler means to cause sound energy to emanate from the coupler means or base plate into the sea floor. Such means may be a hammer-type device or a vibrator-type device. Alternatively, the lower end of the coupler means or the base plate may be driven by means of a vibrator-type device to cause sound waves to emanate from the coupler means or the base plate directly into the sea floor.

Abstract: A perforator for perforating a subsurface formation surrounding a well bore to ensure perforation of channels in a cement sheath surrounding a casing pipe cemented in said well bore comprising a series of stacked plates, each plate containing spaced apart co-planar, pie-shaped linear charges and a co-planar, pie-shaped non-charged spacer arranged between each of said linear charges. There are preferably four linear charges and four non-charged spacers forming each plate. The linear charges on each plate are spaced angularly from the linear charges on each other plate so that the linear charges are aimed at different angular portions of the bore hole.

Abstract: A well perforator system and method employs an electromagnetic wave frequency receiver, one for each of at least two gun intervals, that receives a transmitted signal conveyed through well tubing from the earth's surface. The signal is converted to an electrical pulse which detonates a blasting cap and fires the gun perforators. Each gun interval is a separate system with different activating frequencies and each is separately activated to assure that all the intervals are fired. A timer may be used to activate the electromagnetic wave receiver after the gun is in the well to prevent accidental surface firing of the guns from stray sources of electromagnetic waves. Once in the well, only the transmitted pulses are able to detonate the guns. Once the last interval is fired, a wave frequency-activated gun above the uppermost gun interval is detonated with circulation shots to penetrate only the tubing. This creates an instant, intense pressure drop across the perforations to help in cleanup.

Abstract: A method is disclosed for installing an integrated deck on a platform substructure located in a body of water. The deck is supported on jack-up means which, in turn, are mounted on a rigid pontoon raft having a U-shaped configuration. The jack-up means is capable of raising and lowering the deck to and from, respectively, the substructure and for raising the composite platform from one position and lowering it to another position offshore. The U-shaped opening in the raft is oriented so that the jack-up means on the barge straddles the substructure below the deck. Piles may be driven through the base from the raft and from the platform itself when the raft has been removed from the deck once the deck has been installed on the substructure.

Abstract: A template retaining wall for use in marine environments is composed of a plurality of interconnected, piled, prefabricated templates. Each template comprises a series of vertically extending, horizontally spaced apart legs and a series of battered, horizontally spaced apart legs. The legs are interconnected by horizontally and diagonally extending truss/strut members. A track guide is positioned on one lateral end of each template and a rider guide is positioned on the other lateral end of each template. The rider guide on one template engages the track on an adjacent template. A metal sheet pile is welded between each of the vertical legs and piles, extend through each of the legs into the ground underlying the water. The retaining wall may be curved into a circular configuration to enclose and retain an artificial island or may be formed into other shapes.

The upper receptacle has an internal bore of larger diameter than the bore of the lower receptacle. A first annular shoulder is formed at the junction of the bores. A support shoulder is formed in the lower receptacle at the junction of the bore of the lower receptacle and the inner wall of the lower section. A hanger seat member is positioned on the support shoulder. An outer tubing string positioned in the production casing string has a reduced diameter stinger section provided with an annular external seal unit which sealingly engages the bore wall of the lower receptacle. A second annular shoulder is formed on the outer wall of the outer tubing string at the junction of the outer walls of the outer tubing string and the stinger section.

Abstract: A jet shoe, connected to the lowermost end of a large diameter pipe to be placed in a subsea formation, comprises a cylindrical housing in which is arranged an inner tubular receptacle, a check valve permitting downward flow but preventing upward flow and jet tubes extending from the receptacle through the lower end of the jet shoe. The receptacle, valve and tubes are cemented in the housing. The tubes contain nozzles for jetting fluid to erode formation ahead of the shoe. A stinger arranged on the lower end of a smaller diameter pipe extends into and seals in the receptacle. A closure member on the smaller pipe closes off the upper end of the larger pipe. The smaller pipe and the larger pipe, together with a permanent guide base connected to the upper end of the larger pipe, are lowered to the ocean floor. While jetting fluid through the smaller pipe and out the shoe the formation ahead of the shoe is eroded until the larger pipe reaches a pre-determined depth.
