Abstract: An elevating transporter for lifting and transporting an object includes a base from which depends a plurality of casters for engaging a surface over which the base is rollable. An elongated post supported by the base has upper and lower ends and is externally threaded along at least a portion of its length. An internally threaded collar rotatably carried by the base includes a set of internal threads configured for threadable engagement with, and support of, the external threads of the post such that, when the post does not rotate with respect to the base, and the collar is rotated about a rotation axis with respect to the base, the post is vertically displaced toward one of an uppermost and lowermost elevation. Attached to the post is a load-bearing platform including an upwardly facing load-bearing surface for supporting an object to be elevated and transported.

Abstract: A multilayered polymeric structure having at least two polymeric layers is provided, each layer being a mixture of a polymeric composition with carbon fibrils. The multilayer polymeric structure may include an electrically conductive material between the first and second polymeric layers. A process for making a multilayered polymeric structure for packaging electronic components is also provided. The multilayered polymeric material is used to form trays and packages for containing electrical components.

Abstract: Porous articles impregnated with certain anaerobic polymerizable sealants and having a coating of such sealant on their surface can have such coating removed by dissolving the sealant in an aqueous solution of a surfactant having the general formula X.sup.1 --O(C.sub.2 H.sub.4 O).sub.x X.sup.2. The removal can be done at room temperature.
