Abstract: A packer (100) for sealing an annular region in a wellbore is provided. The packer (100) includes a packing element (150) which is held through bi-directional forces. The packer first comprises an inner mandrel (110). Disposed around the inner mandrel are three tubulars: a top sleeve (120), a bottom sleeve (130), and a booster sleeve (140). A packing element (150) is disposed circumferentially around the outer surface of the booster sleeve (140). The top sleeve (120) and bottom sleeve (130) each include an upper compression member (124,134) which rides across the booster sleeve (140) in order to compress the packing element (150). The packing ele-ment is expanded outward from the packer to engage a surrounding string of casing (10) through compressive forces provided by the top and bottom sleeves (120,130). Thereafter, differential pressure applied above or below the packer acting on the packer element (150) and booster sleeve (140) may provide additional compression of the packer element (150).

Abstract: A laundry washing machine has a cabinet 2 and a drum 1 suspended within the cabinet for rotation about a horizontal axis. The drum 1 includes a pair of drum ends with a pair of vanes 110, 111 extending between the drum ends 11, 12 rigidly connecting the drum ends together. The drum 1 has a substantially cylindrical perforated skin 22 having a main section 34 and a hatch section 35. The main section 34 and hatch section 35 connect along the edges to form the complete drum skin. In an opening operation the drum 1 is opened by disconnecting the edges of the main section 34 and hatch section 35 of the drum skin 22, retaining the hatch section 35 in a fixed position relative to the cabinet 2 and rotating the drum 1 such that the main section 34 of the drum skin 22 moves apart from the hatch section 35 to provide an opening into the drum. The opening is provided in conjunction with an opening into the cabinet, normally closed by a lockable lid 4. The cabinet 2 may comprise a rectangular folded up wrapper 32 together with a water collecting tray 28 fitting within the lower end 33 of the rectangular wrapper. Laundry load guiding flaps 18, 19 are disclosed which hide from view the spaces between the drum 1 and the cabinet 2 with the lid 4 open and the drum 1 in its open condition. These flaps also provide laundry guiding and scraping functions during the opening and closing operations.

Abstract: A targeting system for a portable image reader, which advantageously combines a number of functions including alignment, aiming, framing and range finding and provides a wide imaging range with an optimal field of view, is described. The targeting system projects a predetermined pattern having two or more components onto the target such that the components maintain a uniform distance between one another to bound the target and further vary in size as a function of their distance between the image reader and the target. The targeting system comprises targeting LED's, apertures positioned over the targeting LED's, and cylindrical lenses positioned over the apertures. With this arrangement, at least two vertical lines are projected onto a target such that the lines maintain a uniform distance apart from one another, but vary in length as a function of the reader distance from the target. This allows the operator to quickly position the imaging device over a target.
