Abstract: Disclosed herein are novel buoyancy modules for attachment to a cable, pipe, or umbilical. The buoyancy modules include a pair of module bodies adapted to mate with each other. Each module body has a recess adapted to engage a single bolt tensioner and at least one of the module bodies includes a longitudinal channel running the length of the module body. Further, the module bodies include one or more pads positioned within a pad containment channel. A plurality of single bolt tensioners may be positioned within the recesses of the module bodies and tensioned to impart a compressive force such that the module bodies contact each other, generating a predetermined displacement of the pad and thereby imparting a known clamping force that results in a desired clamping pressure being applied by the pad to the cable pipe or umbilical.

Abstract: A cleaning kit. The cleaning kit including a first liquid-tight container including a solute and a second liquid-tight container including a solvent adapted to be received within the first container to be ruptured by the application of pressure to the container by a user. The second container includes a sealable liquid-tight pouch; and a frangible seal along at least a portion of an outer edge of the pouch, wherein the frangible seal is broken by the application of pressure to the second container by a user greater than about 30 inches of water when tested according to ASTM Test F1140-07 (2007), wherein the second container is adapted to be openable while it is located in the first container to release the solvent from the second container into the first container, whereby the solute and the solvent are combined to form a cleaning liquid.

Abstract: The present invention relates to both a material construction and manufacturing method resulting in low density materials, especially for use as subsea buoyancy and insulation. The products are made by an additive manufacturing process, printing thin layers of a polymer material while leaving voids of precisely predetermined shapes, sizes and distribution, with precisely predetermined thicknesses between the voids. The resulting products provide optimized strength, buoyancy and insulative value with minimal material usage and density.

Abstract: Segments of open framework auxiliary clamps are fastened together around a drilling riser. The clamps have depressions which mate with recesses in caps to hold auxiliary lines. Larger depressions and recesses hold choke and kill lines. The caps of the choke and kill clamps are extended radially through openings in buoyancy covers as mux clamp mounts. Extensions on mux clamps engage slots in the mux clamp mounts. Opposing channels in the mux clamps and covers hold inserts, with grooves in which multiplex lines are mounted.

Abstract: Buoyancy modules for subsea riser pipes are made of syntactic foam solid cores covered with tough high density polyethylene shells. Inner surfaces have partial semi-cylindrical surfaces to fit the riser pipes. Internal radial grooves hold flexible contact pads. Recesses in the inner surfaces hold auxiliary lines. Flat surfaces between the inner and outer semi-cylindrical surfaces have complementary longitudinally extending semi-cylindrical grooves to position choke and kill lines. Grooves in the outer semi-cylindrical surfaces hold composite fiber tensioning straps directly outward from the flexible contact pads. Flat areas of the grooves hold tensioning hardware. Tensioning the straps grips the riser pipe with the pads and grips the choke and kill lines in the semi-circular grooves. Cavities in the ends allow the buoyancy module halves to be assembled on the riser pipe around clamps which hold the accompanying lines.

Abstract: Tape partially curves around a one-way tape brake for a cassette. The brake has a cylindrical roller with a side extension. When the tape advances, a smooth cylindrical side of the roller allows tape forward movement. When the tape tends to reverse the tape pulls a friction surface rearward, turning the roller and frictionally engaging the tape and pinching it against a tape guide. Rearward tape motion is prevented.

Abstract: A new CD package has a cover attached to a tray by a single hinge at one end of the tray. That simplified manufacture and assembly makes the entire cover available for printing and graphics. The CD package is assembled with a single direction motion of a paper board cover toward a plastic tray. The entire cover surface is available for graphics, and the complete package lies flat on either side when fully or partially opened. A hook folded on one paper board flap engages a ledge in the receiver. A flap on one paper board cover is slit and glued or physically attached to a hinged extension on the tray. When the flap is formed on one end of the cover, the cover wraps around the tray. When the flap is formed in the middle of a cover, the CD package opens like a book. More than one connector flap may be provided for connecting the cover to multiple trays. The trays may be double-sided with a central opening in a central platform to receive snap-in and twist-in rosettes.

Abstract: An integrally molded video cassette is formed with an integral living hinge between the body of the cassette and the dust cover. An energy absorption zone formed near the hinge isolates the hinge from directly transferring high impact forces between the relatively low mass dust door cover and the high mass cassette body loaded with reels and tape. Energy absorption zones are formed of relatively thin wall areas with radiused intersections. One or more radiused grooves are formed in the wall sections.

Abstract: A video cassette is labeled with a wrap around label attached to the cover, to the back and to the bottom of the video cassette. The label has perforations for detachment of the bottom section. A clear film can be attached peripherally around an opening in the label for viewing a reel and hub within the video cassette. Portions of the cassette are molded as openings between the interior and exterior to reduce material costs, and are subsequently covered with the wrap around label. The invention is a lower cost molded video cassette with increased display area and removable label section, which can be put to various uses, such as an information card for future reference.

Abstract: A machine optics and paper path cleaner has a relatively stiff backing sheet and a cleaning sheet attached to the backing sheet at a position spaced from the leading edge. The cleaning sheet is folded, flocked or flapped, knitted or engraved with surface variations to aid in the cleaning of paper paths and optics. Wet cleaners are held in absorbent materials and in frangible or openable reservoirs to wet the cleaning material as it is drawn into the machine through the paper path and across the optics. The cleaners are made in single foam sheets of varied thickness and in laminated sheets of stiff backing material and flexible cleaning material.

Abstract: An integrally molded polypropylene tape cassette has a base with vertical first and second side walls. A rear wall is attached to the base by an integral hinge. A cover attached to the rear wall by an integral hinge, and a dust door attached to the cover by an integral hinge. Snaps between the cover and base connect and close the apparatus with integral springs pressing on tape reel hubs. The dust door covers a forward wall protruding from the base between the first and second side walls. The forward wall has slots and posts for allowing passing of the tape between the interior and exterior of the cassette. The cassette further includes a dust door latch which is integrally molded with one of the sides of the tape. An integrally molded tape hub brake is positioned between the hubs for locking the hub flanges when the cassette is not in use the entire cassette is made of polypropylene material.

Abstract: A dust door arrangement which avoids spring clip malfunction and enhances video cassette longevity. Reduced width of cavities containing first and second side hinges between the dust door and the video cassette cover improve hinge flexibility and operation and eliminate hold down spring clips catching when the video cassette is being withdrawn from a VCR. The dust door, hinge and cover are integrally molded, with the hinge lying below the surface of the cover of the video cassette and providing an axis of rotation for the door with respect to the cover. The hinge and cavity are approximately of the same width and are about two to four times as wide as the thickness of the dust door side walls. A supplemental spring is preferably provided to bias the dust door downward. The dust door first and second thin side walls have bevelled tops with extended steps which form first and second hinges. Flat tops of the hinges oppositely mate with first and second extensions extending down from the cover.
