Abstract: A water safety garment and apparatus configured to avoid drowning can be configured to permit submergence for a predetermined period of time without inflation. After the predetermined time has passed, the garment or other apparatus can be configured to inflate to help a person wearing the garment float on top of the water to avoid drowning or other potentially harmful condition that may result from being underwater for too long. In some embodiments, a circuit may be utilized to detect the submergence condition of a person wearing the apparatus or garment. Upon a determination that the detected submergence condition has occurred continuously for a pre-determined period of time, an inflation mechanism can be actuated to force the person wearing the apparatus or garment to float to the top of the water.

Abstract: In a dispenser for dispensing rolls of paper towel including means for rotatably mounting the roll, a feed nip including a segmented drive roll with a plurality of drive surfaces and a nip roll adapted to cooperate therewith to advance the towel to a dispensing chute, an improved drive roll having an elongate axis and a plurality of drive segments defining drive surfaces disposed along its length of generally equal radius with respect to the elongate axis of the roll, as well as a plurality of guide disks interposed between adjacent drive segments configured to alleviate wrinkling as the towel is dispensed. Further improvements include a textured delivery chute and a method for dispensing a partially depleted roll of towel together with a fresh roll.

Abstract: A method of lining a drilled bore comprises running an expandable first tubular into a bore and locating a portion of the first tubular in an unlined section of the bore and another portion of the first tubular overlapping a portion of an existing second tubular. The first tubular is secured relative to the second tubular while retaining the provision of fluid outlets to permit displacement of fluid from an annulus between the first tubular and the bore wall. An expansion device is then run through the first tubular to expand the first tubular to a larger diameter. Cement is then circulated into the annulus between the expanded first tubular and the bore wall. The fluid outlets are then closed.

Abstract: The invention concerns the sealing of tubing, and in particular the sealing of a joint between expandable tubing sections. In one embodiment, there is disclosed expandable tubing such as an expandable liner comprising at least two expandable tubing sections which are adapted to be coupled together, and a seal adapted to be located around the expandable tubing sections, to seal a joint between the sections.

Abstract: Methods and apparatus for expanding a tubular with the aid of a compressive force are disclosed. A tubular is run into a wellbore. While the tubular is in a compressive state, the tubular is expanded into its desired form. The expanded tubular can be used for multiple downhole functions such as completing multilateral junctions in a wellbore, patching apertures in a wellbore and lining a wellbore.

Abstract: An expandable tubing assembly comprises a tubular connector defining overlapping longitudinal slots, the connector comprising end portions and an intermediate portion. The slots extend over the whole length of the connector, but the only slot overlap occurs in the intermediate portion. The assembly further comprises lengths of expandable tubing defining overlapping longitudinal slots and having end portions defining nodes between and beyond the ends of the tubing slots. Tubing threads are formed on the end most tubing nodes. The connector end portions define threads and are coupled with the threads formed on the nodes of the respective end portions of the tubing lengths.

Abstract: There are disclosed methods and apparatus for expanding tubing downhole. In one embodiment, there is disclosed a method of expanding downhole tubing such as a liner (10), the method comprising the steps of locating the liner (10) in a borehole (12), expanding a part (16) of the liner (10) in the borehole (12), locating an expansion device such as an expandable cone (18) in said expanded part (16) of the liner (10), and translating the cone (18) relative to the liner (10) to expand a further part (20) of the liner (10).

Abstract: A tubing coupling method is provided. In one aspect, the method comprises providing a length of expandable tubing and a length of larger diameter non-expanding tubing, connecting an end portion of the expandable tubing to an end portion of the non-expanding tubing, running the tubing into a bore, and expanding the expandable tubing. The expandable tubing may form part of an expandable well or sand screen, or may be an expandable bore liner.
