    摘要: The present invention provides an apparatus for use in a peristaltic pump 20 which prevents an inadvertent free flow condition prior to loading or after removal of an I.V. tube 26 in the peristaltic pump 20 and which also prevents the inadvertent occlusion of a loaded I.V. tube 26 in the peristaltic pump 20. A standard I.V. tube 26 has a slide clamp 109 provided thereon. The apparatus includes an I.V. tube groove 29 into which the I.V. tube 26 is positioned, a slide clamp receiving area 62 into which the slide clamp 109 is inserted, and a biased sliding member 81 which the inserted slide clamp 109 engages such that the I.V. tube 26 cannot be loaded into the apparatus without the slide clamp 109 occluding the I.V. tube 26. The present invention also contemplates a slide clamp 109, compatible with the apparatus having a surface pad 125 for facilitating automated identification of the slide clamp 109, in cooperation with a nonobstructive sensor 85 in the safety apparatus. The present invention further contemplates a slide clamp 109'. having an I.V. tube receiving aperture 110'with an inner diameter profile which minimizes friction between I.V. tube contacting surfaces 126 of the aperture 110'as an I.V. tube 26 is slid transverse to its length within the aperture 110' and which has a surface pad 125 for facilitating automated identification of the slide clamp.

    摘要: A Hall effect thruster for propelling spacecraft and satellites includes at least two acceleration channels, each of the channels has a closed end and an open end, and a plurality of flux guides adjacent each of the channels. The plurality of flux guides includes an innermost flux guide, an outermost flux guide, and at least one intermediate flux guide. Each intermediate flux guide helps provide a magnetic field to each of two adjacent acceleration channels.

    摘要: In forming flemish eyes at the ends of wire ropes to produce e.g. slings, serious difficulties arise when forming the anchorage for the spliced loops if the rope is of large diameter. The terminal end of the rope material has its component strands naturally laid on the rope, and it has been proposed to enclose the naturally laid strands in a cylindrical sleeve adjacent to the loop and introduce a hardenable anchoring material such as a resin into the sleeve to complete the anchorage.It is now found that improved loading distribution on a wire rope can be obtained through providing an anchorage for the loop in the form of a sleeve comprising a socket, and flaring-out into the socket the component wires of portions of the strands remote from the loop, the strand portions adjacent to the loop remaining naturally laid on the rope.
