A design is presented for a structured cable suitable for carrying a large electric current in a cable-in-conduit comprising an assembly of rectangular stacks of thin superconducting tapes, with provisions for mechanical support of large mechanical stress and cross-flow of cooling fluid capable of removing large amounts of heat.

Blocks-in-conduit cable using high-temperature superconducting tape

A composite billet includes an array of textured-powder bars in a geometry that is compatible with assembly and drawing of a billet with LAR˜1:1. A method is presented of compressing the bars suitable for the billet geometry in an inert gas environment. Methods of drawing of the billet control the deformation of the composite billet during area-reducing draw to fine wire so that the shape and registration of the constituent bars is preserved. Lastly a method is disclosed to fabricate a cable-in-conduit conductor containing the textured-powder Bi-2212/Ag wires that enables robust forming of windings and also provides in-cable containment of a buffer gas flow under high pressure during the high-temperature heat treatment of the winding that is required to produce optimum superconducting performance in the winding.

Textured-powder Bi-2212/Ag wire and method of fabrication

A wheel frame for supporting at least two wheels along the bottom surface of a vacuum inlet nozzle of the type commonly used for vacuuming concrete floors of shops and other areas which have cement or wooden floors. The wheel frame is rectangular and has preferably two wheels held by the frame. The frame fits over the conventional vacuum nozzle and snaps over the flange at the bottom of the vacuum nozzle. The wheels are positioned so that they are near the back of the nozzle so that the front edge of the nozzle can be lifted by tilting the nozzle toward the back. This greatly facilitates the vacuuming up of leaves and other larger objects which do not fit under the front edge of the conventional vacuum nozzle.
