摘要： In a conveyor system for cylindrical objects, a gravity feed surface means is employed together with moving side rails or their equivalent, to organize such objects in a uniform manner as they proceed down the surface means. The system further contemplates such a surface means as a temporary, in-line storage section where the objects are permitted to back up, while being continuously biased forward by gravity; and in combination therewith, means for releasably retaining the objects against such bias to create a flow or stop condition as demanded by need; and most optimally, a sensing means for determining the amount of such back up for controlling the input of such objects to the surface means, and means for indicating the absence of objects in a critical area of the system, the operation of the retaining means between the flow and stop conditions being subject to such indicating means. Also disclosed in the combination, is an elevator means for lifting and transferring the objects between a series of two or more of such surface means.

摘要： This disclosure relates to the art of extruding plastic tubular film of the type having circumferentially spaced apart, thickened sections or profiles which extend continuously in the axial direction, and which are configured to interlock mechanically to provide a zipper-like fastener integrally formed in the film. Such film is extruded as a bubble or tube supported by internal air pressure, and in the preferred practice, is shortly after extrusion, captured between a pair of elongated racks such as of aligned rollers which are air-cooled or otherwise cooled. The racks serve to engage and draw heat rapidly out of the profiles to avoid certain disfigurations therein, can be used to control the hoop tension in select areas of the bubble, and are compatible generally with maintaining a stable bubble.

摘要： In the direct chill casting of metal ingots wherein the coolant is removed from the ingot surface shortly below the mold to permit a reheating of the ingot surface, the improvement which comprises reapplying the coolant to the ingot surface at a somewhat lower level corresponding approximately to the level of the bottom of the molten metal pool. The improved method reduces ingot cracking and permits higher ingot casting speeds by preventing the generation of excessive internal stresses during solidification and further cooling of the ingot.
