Abstract: ABSTRACT OF THE DISCLOSURE          There is disclosed a non-pneumatic tire for mounting on a rim having axially spaced mounting flanges.          The tire is formed with a radially exterior tread surface having axially outwardly sloped side walls projecting radially inwardly therefrom and formed on their radially inwardly extremities with shoulders that nest against the radially outward edges of the mounting flanges.  Retaining flanges then project radially inwardly therefrom for re-tention on the axially inner sides of the mounting flanges.          The tread surface and opposite side walls co-operate to form a circumferential interior cavity in which a latticework of webbing is formed by axially extending interrupter webs which are spaced equidistance about such cavity and have an annular projecting band circumferentially thereabout and connected with such axially projecting interrupter webs.          The tread; sidewalls, flanges and webbing are all preferably constructed of resilient elastic material such as polyure-thane and have a circumferential length approximately 10% less than the circumferential distance around the rim.  This provides an elastic constraining force when the tire is stretched over the rim.  Also, elastic endless belts or beads may be embedded in the retaining flanges to provide further securing force maintaining the tire on such rim.

Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus is provided for handling bobbins and particu-larly for transferring bobbins from one location to another.  The apparatus includes a cart having parallel linkages pivotally mounted theron and connected to a fluid-operated ram.  A bobbin-engaging unit is carried at the ends of the linkages and engages the bobbin internally.  After engagement, the linkages are manipulated to transfer the bobbin to another location with the weight of the bobbin and mechanism being offset by the fluid-operated cylinder.  The cart is designed to be attached to a portable bobbin buggy so that both can then be pushed as a unit to move the buggy to a desired location from which the bobbins are transferred to a creel or rack, for example.           This invention relates to apparatus for handling bobbins or the like and for transferring them from one location to another.         Bobbins or spools of filaments, strands, threads, yarn, roving, and the like produced in textile mills often weigh 25-30 lbs. or more with some being in the order of 100 lbs. It is tiring for workers to handle a multiplicity of such bobbins over the course of a day.  Also, the bobbins may be mishandled and damaged, parti-culary by a tired worker, and moisture from the hands may be damaging to the filaments, etc.

Abstract: ABSTRACT OF THE DISCLOSURE The entrainment of reaction medium in the vapor phase and the entrainment of gaseous phase in liquid phase are decreased in a chlorine dioxide generator producing a gaseous mixture of chlorine dioxide, chlorine and steam from a boiling reaction medium and wherein generator liquor is recycled with make up chemicals.  These results are achieved by generator modifications, which include tangential entry of recycled liquor to the generator in the vapor space above the liquid level in the generator, and the provision of a baffle projecting inwardly from the generator wall in the vapor space and arranged to be above the trajec-tory of the recycled liquor as it enters the generator. These modifications enable the generator volume to be de-creased substantially, with consequentially decreased capital costs.
