The endless belt structure (11) further comprises a zipper (19) for releasably connecting the two longitudinal edges (17, 18) together so as to form a tubular structure (21) having a flexible side wall (22). The circulating path (12) includes an assembly zone (33) at which the longitudinal edges (17, 18) of the belt portion (15) are brought together and interconnected by way of the zipper (19) to form the tubular structure (21), and a disassembly zone (35) at which the zipper (19) is released to separate the longitudinal edges (17, 18) and the tubular structure (21) subsequently opened. Means (90, 110) are provided for compressing the tubular structure (21) along a portion thereof to express liquid from the material contained in the tubular structure (21). The liquid so released can discharge from the tubular structure (21) through the water permeable belt portion (15).

Abstract: Apparatus for clearing particles from a lateral drilling operation in strata beside a well. The drilling apparatus is part of a down hole unit and is configured for extending from a lateral opening of the unit into a lateral passage in the adjacent strata, and the operation of the drilling apparatus discharges particles from the lateral passage toward the lateral opening. The invention deflects or redirects the particles discharged from the lateral passage, away from the lateral opening, to prevent clogging or blocking of an internal passage or elbow through the down hole unit, using a pressurized fluid such as a gas or an emulsion. The pressurized fluid can also be configured for carrying the particles upwardly through the well to the surface, and for reducing or removing a hydrostatic head in the well.

Abstract: An intraocular lens is disclosed, with an optic (21,28,43,63,82,111,130,200,230) that changes shape in response to a deforming force exerted by the zonules of the eye. A haptic (23,30,42,62,81,112,120,190,220) supports the optic around its equator and couples the optic to the capsular bag of the eye. The haptic may be pre-stressed before the optic is placed within it. After such placement, the pre-stress may be relieved, and the haptic may produce stress in the optic. The pre-stress may produce a radial tension or a radial compression in the optic. Alternatively, once the optic is placed within the haptic, both may undergo a process that changes the size and/or shape of one with respect to the other, causing a stress within the optic. This process may produce a radial tension or a radial compression in the optic. The haptic may include an annular ring having outer and inner diameters that may depend on the stiffness of the haptic.
