Abstract: In a method and apparatus for winding strand material into a package on a mandrel rotated at a progressively decreasing speed, the strand material being guided adjacent the package build by a guide member reciprocated by a cam. The cam speed is repeatedly or continuously increased relative to that of the mandrel to counteract or even eliminate reduction of the helix angle at which the strand material is deposited on the package build.

Abstract: A stove for burning solid fuel such as wood, coal or briquets in a more efficient manner utilizes preheated outside air for primary and secondary combustion and has tempered glass windows for observation. The combustion air flow is directed so as to minimize obscuring of the glass by deposits of unburned volatiles. A fire chamber is provided with self-feeding grate, and the stove also has a secondary grate, a high proportion of radiating and convective surfaces, a heat exchanger, a cooking surface, an automatic linkage between a fuel loading door and an opening-reducing damper to limit back drafts and thermostatic control to ensure complete combustion and efficient heat exchange. The self-feeding grate has a thermostatic grate shaker to promote unattended complete combustion, and can be replaced to match the fuel used.

Abstract: An apparatus and method for winding a multistrand roving package by guiding a plurality of strands along convergent paths of travel towards a winding mandrel employ a pair of spaced strand guide members in the vicinity of the mandrel. The guide members define a gap for the strands and are reciprocated parallel to the mandrel axis so as to alternately engage and deflect the strands into a side-by-side relationship in the package. The strand guide members each have strand guide edge portions so located that, transversely of the mandrel axis, they are offset towards the mandrel from a linearly disposed relationship to intersect the strand paths at different respective angles corresponding to the differences in direction of the strand paths, thereby to compensate for differences in the strand deflections resulting from the differences in direction of the strand paths and to improve the strand deposition.
