摘要:
A propulsion and stabilization system comprising a series of FIG. 8 coils mounted vertically on the walls of the guideway to provide suspension, lateral guidance and propulsion of a magnetically levitated vehicle. This system further allows for altering the magnetic field effects by changing the relative position of the loops comprising the FIG. 8 coils either longitudinally and/or vertically with resulting changes in the propulsion, the vertical stability, and the suspension.

A grape or fruit box includes a pair of laterally spaced, rigid ends, to which is secured a wrap assembly of paper overlay laminated veneer, extending substantially about the sides and bottom of the box. The ends are each formed with a groove extending from the right to left side of the end, and relatively closely adjacent the upper edge of the end. The groove extends parallel to the upper side of the end, and the lower edge of the groove is chamfered or bevelled along its entire length. The box lid or cover pad comprises a relatively thin and flexible sheet of laminated veneer or heavyweight paper. To secure the cover pad to the box, one end of the lid may be inserted in one groove of one end, and the lid then bowed upwardly in its center area, so that the opposite end of the lid may be located below the groove in the opposite end. By then pulling upwardly on that opposite pad end, the latter will snap into the groove, facilitated by the lower, chamfered edge of the groove.
摘要:
A tool for bending metal wire hangers such as those used for hanging false ceilings below exposed under floor structures of the type separating successive floors in modern multiple story commercial buildings and in other buildings where a lowered ceiling is desired. The wire bending tool includes a pair of operating handles connected to a gripping jaw having members for holding a wire to be bent. The gripping jaw forms part of a rectangular block to which a third handle is pivotally mounted. The third handle is associated with a roller which cooperates with two corners of the block to bend the wire into two successive right angles as a third handle is pivoted about its axial connection on the rectangular block.
