Abstract: A clamp for supporting a subsea wellhead and attached casing string preparatory to installing same in a well, and slip bowl assembly for running a drill pipe cementing string inside the casing string. The clamp comprises two hinged together clamp halves with a connector to permit the clamp to be locked about a subsea wellhead. Half-circle cutouts in each clamp half form a clamp bore when the clamp is closed. The clamp bore has a grooved profile to mate with a grooved profile on the exterior of the subsea wellhead. When the subsea wellhead is clamped in place, with the clamp resting on the rig floor, a slip bowl assembly having a grooved base plate is placed atop the clamp.

Abstract: A non-rotating cement wiper plug has an insert, with inner and outer telescoping sleeves, within a resilient outer body. The outer body has annular fins which bear against a casing wall. The inner sleeve has a tapering nose within a tapered cavity in the outer sleeve. Slots in the outer sleeve form a plurality of segments. The inner and outer sleeves are preferably of a frangible material. When the plug is pumped down and lodges against downhole float equipment, pump pressure compresses the plug, forces the inner sleeve down within the outer sleeve, forces the segments radially outward, and fractures or separates the outer sleeve segments. The outer body is forced against the casing wall so tightly that it cannot rotate in response to the forces from a rotary drill bit. Lock surfaces on the inner and outer sleeves lock them together and maintain the outer body in its forced-outwardly position.

Abstract: A gun holder for use in vehicles comprises a pair of elongated bendable sidewalls having upper and lower portions. The upper portions of the sidewalls are joined by a strip of flexible material. The cross-sectional shape of the sidewalls forms generally a “V” shape, and when the lower narrow edge of the V is inserted into a seating gap in a vehicle seat, an open, upwardly facing pocket is formed by the flexible sheet material and the sidewalls. A gun may then be inserted into the pocket, and is securely held there for increased safety and protection of the gun, while still permitting very rapid access to the gun when desired.

Abstract: A method for determining the oil and grease concentration of aqueous solutions on offshore facilities without having to ship the aqueous solutions to shore-based laboratories for analysis. The method generally involves a liquid-liquid extraction procedure, where a concentration of oil and grease extracted from a known volume of aqueous solution is determined using a pair of weighing devices, which are connected to a common computer which is capable of processing synchronized data points received from the two weighing devices. The first weighing device is a control scale upon which a reference mass having a known weight is placed. The second weighing device is a sample scale upon which the extracted oil and grease will be placed.

Abstract: Apparatus for positioning a power tong at a desired location with respect to the distance above the rig floor, and with respect to the center of the rig floor. A pedestal is secured to the structure of the rig. An upright member is mounted on the upper end of the pedestal, with a bearing disposed between the upright member and the pedestal, the bearing permitting the upright member to rotate around a vertical axis when moved by a powered ring gear assembly. A telescoping boom is rotatably mounted on the upright member, and one end thereof extends over the central part of the rig floor. Power tongs attached to the boom may thereby be positioned at desired positions with respect to the rig floor. Controls mounted on the power tongs and/or on the upright member permit control of the rotation of the boom, the upright member, and the power tong.

Abstract: Game of chance for spectators at ball games conducted in enclosed play areas, particularly indoor football games. Around the playing area at the field level are a number of dasherboards, each with a given advertiser's logo thereon. Striking the dasherboards, by either a player's body who has gone out of bounds, or by a ball, generates a logo “strike” corresponding to the logo on that dasherboard. Over the course of a game, usually a number of such strikes occur. Spectators hold game cards bearing an arrangement of logos, similar to a conventional “bingo” card, and mark the logos on the card corresponding to the logo on a dasherboard which has been struck. Achieving some defined pattern of marked logos, or marking of even a single “bonus” logo, results in a prize for that spectator card holder.

Abstract: Apparatus for twisting off crown bottle caps. A main body in side view is flattened and has a thickness, with a circular opening through the thickness, the opening large enough to accommodate the diameter of a crown bottle cap. The circumferential edge of the opening is formed into a plurality of pairs of facets, each pair of facets forming a notch. The walls of the facets are not parallel to one another but instead taper toward one another and form generally pyramidal shapes which intersect, or come to a point, within the main body thickness. An inverted triangular shape is formed between each pair of facets. A bottle cap is inserted into the opening, where the notches formed by the facets closely engage the bottle cap jags. The contour of the main body then permits the user to readily twist off the bottle cap.

Abstract: A protector for placement over subsea wellheads. A main body is cylindrical, with an inner diameter of sufficiant size to fit over a subsea wellhead. One end of the main body has a cap across it. A vent and a pump-through port, which permits pumping in of corrosion inhibitors, is in the cap. The open end of the main body has an outwardly flaring skirt to help guide the protector into place over the wellhead. The main body is formed from polyurethane via molding or other suitable methods.

Abstract: A combination food preparation and handling tool comprises a handled main blade body, a turning hook, and a pair of legs protruding from the main blade body. In the preferred embodiment, the turning hook is integrally formed from an extended and pointed tip of the main blade body formed into the desired shape and bent at an angle to the main blade body. One edge of the main blade body is preferably arcuate in shape and sharpened to form a primary cutting edge. The legs can form a bottle de-capper and a secondary cutting edge. The preferred arrangement of the main blade body, the turning hook and the legs forms a likeness of a legged animal, such as an alligator. Further enhancement of the animal appearance may be had through etchings or engravings on the main blade body to represent other features of the animal.

Abstract: A coupler system for downhole wellbore service tools comprises an elongated main body having a longitudinal bore, a plurality of release blocks disposed in slots in the main body wall, and an exterior spline about its circumference below the release blocks. The release blocks are movable radially inward and outward, and are biased inward by springs. A piston having a longitudinal bore is movably disposed within the main body bore. The piston has spaced apart larger diameter sections and a central smaller diameter section. A cylindrical washpipe body fits over the main body and has an internal spline for engagement with the main body spline, and shoulders (on the main body and on the interior of the washpipe body) limit downward movement of the washpipe body.

Abstract: A trailer-mounted, retractable elevated hunting stand, especially but not exclusively suitable for deer hunting. The stand comprises a wheeled trailer, suitable for pulling behind a tow vehicle. The elevated stand is hingedly mounted on the trailer in a “jack-knife” configuration, with a main shaft mounted via a hinge to the trailer, and a platform atop the shaft. The platform is hinged to permit rotation for compact storage. A spring biases the shaft toward a vertical position. To use the stand, the shaft is rotated to the vertical position and the seating platform is rotated on its shaft mounting so as to be substantially horizontal when the shaft is vertical. The shaft is then locked in place. A ladder permits access to the elevated platform. The shaft telescopes for additional height if desired. The trailer permits hauling of an ATV when the stand is retracted.

Abstract: A buoyantly moveable, self-elevating (jack-up) artificial work island or platform self-assembled while floating upon a work body of water by reversibly coupling together a plurality of independently buoyant modular hull components (20, 30), each of which is relatively narrow beam and capable of navigation through relatively narrow waterways. After self-assembly, the work platform is self-elevating upon a plurality of legs (51, 52, 53) to a desired distance above the work body of water. The work platform may be buoyantly moved to subsequent work locations as a unit, or separated into modular hull components each of which may be buoyantly moved separately to the subsequent locations. The work platform may further have a drilling derrick, a hoist, drilling fluid pumps, a rotary table and other equipment associated with earthboring for oil and gas installed thereon. The work platform may be elevated above the water surface a sufficient distance to accomodate operational conditions.

The rack is adjustable to accommodate many different types of tubular goods, and keep such different tubular goods segregated from one another. A horizontal track is provided with at least two vertical divider posts which can slide along the length of the track. The vertical divider posts can be locked in place at desired intervals along the horizontal track, thereby defining a plurality of compartments for holding pipe or other tubular goods.

Abstract: A buoyantly moveable, self-elevating (jack-up) artificial work island economically and quickly self-assembled while floating upon work body of water by reversibly coupling together a plurality of independently buoyant modular hull components each of which is of relatively narrow beam and therefore capable of navigation though relatively narrow water-ways. After self-assembly said artificial work island is self-elevating upon a plurality of legs a desired distance above said work body of water. The island may be buoyantly moved to subsequent work locations as a unit or separated into modular hull components each of which may be buoyantly moved separately to the subsequent locations. The island may have a drilling derrick, a hoist, drilling fluid pumps, a rotary table and other equipment associated with earthboring for oil and gas installed thereon.

Abstract: A snubbing unit drilling system which includes a power tong and a hydraulically activated back-up tong. A mounting structure having a rotating slip assembly positioned thereon such that the rotating slip assembly rotates relative to the mounting structure. A plurality of support legs are attached between the power tong, the back-up tong, and the mounting structure such that the support legs prevent relative rotation between the power tong and the mounting structure.

Abstract: A power tong set, with lead and back-up tongs, is mounted on the slip bowl of the traveling jack head of a snubbing unit and rotates with the slip bowl. Service lines (or umbelicals) for the tong set are not connected during string rotation. In an alternate version of the apparatus a fluid feed through swivel is mounted on the tong set, secured to the necessary tong operating and control service fluid line, or lines, such that the tong set can rotate with tong service lines between the tong set and the snubbing unit attached during rotation. In an alternate form, the tong set is mounted on the jack head, independently of the rotary table, and the tong set does not rotate when the rotary table rotates.
