Abstract: A CNG fuel supply system is provided for mounting a plurality of Type 4 tanks on the roof of a bus. A manifold line extends to the roof of the bus and is anchored against movement relative to the length of the bus. A shutoff valve is associated with each tank, the shutoff valve being mounted on an end of its respective tank adjacent the manifold line. The shutoff valve has two ports which communicate with the tank when the shutoff valve is open. An inlet tubing piece connects the manifold line to one of the two ports of each tank and an outlet tubing piece connects the manifold line to the other port of each tank. The tubing pieces are manufactured to be substantially identical to other tubing pieces of the tank system for a given bus, and to other tubing pieces for other buses in the fleet, thus reducing the number of different tubing pieces utilized for construction and maintenance of the fleet.

Abstract: A nappable, dimensionally stable fabric is produced on a three bar warp knitting machine by over feeding the yarns fed by the bottom bar to provide nappable loops, and by knitting the yarns fed by the top bar in a pattern providing nappable floats, longitudinal stability being provided by yarns knit from the middle bar, and lateral stability being provided by the partially napped floats.

Abstract: An armored cable assembly for locking cycles and the like comprising a cable with a welded inner fitting at each end surrounded by a metal sheet or conduit, the end of such sheet and said inner fitting extending into a cylindrical recess in each of a pair of outer fittings and being secured therein by a pin extending through said outer and inner fittings, in a direction normal to the axis of said cable. The outer fittings have each a hole through which the shackle of a padlock may be passed for securing the ends of the cable assembly.

Abstract: A swimming pool cover support frame comprising a plurality of elongated floating elements such as inflated tube sections which are fastened together pivotally and removably at their juxtaposed ends, and which are removably attached to the pool edge at their other ends.
