    摘要： Embodiments of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such embodiments can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some embodiments can include a sheath with inner and outer layers, where a folded portion of the inner layer extends through a slit in the outer layer and a portion of the outer layer overlaps the folded portion of the inner layer. Some embodiments include an elastic outer cover positioned outside the outer layer. Embodiments of the present expandable sheath can avoid the need for multiple insertions for the dilation of the vessel, thus offering advantages over prior art introducer sheaths.

    摘要： A roller transport conveyor and method provides a device for conveying items along a plurality of rollers, in which the device may be set up and operated and serviced by manually raising and lowering one or more contact members that transmit force from a spring to urge a drive belt into contact with an underside of the rollers. The contact member is adjustable by raising and lowering the contact member to expand and contract the spring, or by raising and lowering a base on which the spring is supported, so that the drive belt may be engaged with and disengaged from the rollers. A gravity take-up includes a mass suspended from a cable that is routed to a pulley having the drive belt reeved thereon. The cable is wound upon a winch that compensates for belt stretch, or for belts of various lengths.

    摘要： A radiation-curable silicone release composition is described which comprises (A) a mixture of organopolysiloxanes characterized by the formulaRSi(CH.sub.3).sub.2 --O--(Si(CH.sub.3).sub.2 O).sub.n (Si(CH.sub.3)(R)O).sub.m Si(CH.sub.3).sub.2 R (I)wherein the mixture comprises (A-1) from about 25% to 95% by weight of at least one organopolysiloxane characterized by Formula I wherein each R is --R.sup.1 --O(O)C--C(R.sup.2).dbd.CH.sub.2, R.sup.1 is a hydrocarbylene group, R.sup.2 is hydrogen or a methyl or ethyl group, m is a number from about 1 to about 15, and n is a number from about 50 to about 300, and (A-2) from about 5% to 75% by weight of at least one other organopolysiloxane characterized by Formula I wherein R is --R.sup.1 --OCH.sub.2 CH(OH)--CH.sub.2 O(O)C--C(R.sup.2).dbd.CH.sub.2, R.sup.1 is a hydrocarbylene group, R.sup.2 is hydrogen or a methyl or ethyl group, m is a number from about 1 to about 25, and n is a number from about 50 to about 300, and (B) from 0% to about 5% by weight of a photoinitiator. A method of producing silicone release-coated substrates, the release-coated articles thus produced, and multi-layer articles or constructions incorporating a silicone-release layer also are described. When the silicone compositions are cured such as by electron beam radiation, the cured compositions exhibit a desirable high and controlled release force at high speeds such as the speeds utilized in label processing.
