摘要： Marbleized cookie dough pieces are formed by independently feeding different color doughs into a common extrusion die, in which a rotating impeller is located. The impeller lards portions of each dough into the flow of the other to produce a spiral pattern in the extrudate which is sliced to produce spirally marbleized dough pieces.

摘要： The specification discloses a system and process for producing discrete chilled products having preselected weights from a semi-fluid mixture. The semi-fluid mixture is pumped along a distribution path to an extruding manifold which extrudes a plurality of parallel continuous lengths of the mixture. The continuous lengths are directed through a chilling station in a parallel relationship in order to chill and firm the lengths such that the lengths maintain their extruded cross-sectional configuration. A cutter periodically severs the continuous lengths at predetermined intervals to provide a plurality of discrete products having predetermined weights. The pumping rate, rate of travel through the freezer and periodic severing of the continuous lengths may be selectively varied in order to maintain any desired weight of the discrete products.

摘要： The discharge device of this invention serves to receive axially compressed radially self-sustaining tubular duct in a cartridge form substantially shorter than the fully extended length of the duct and has a restraining collar on an exit end of the discharge device which effects a hoop tension on the compressed core during its passage from the exit end of the device to apply a controlled frictional drag ensuring that the core upon discharge is in a fully extended condition.

摘要： Thermoforming apparatus wherein the opposite longitudinal edge portions of a sheet of thermoplastic material are gripped by an indexing conveyor which conveys the sheet through a heating oven wherein it is heated to forming temperature and through a thermoformer wherein the heated sheet is deformed into a mold cavity by pressure and/or vacuum, said apparatus being characterized in that at least the portion of the length of the heating oven adjacent the thermoformer has therein one or more perforated tubes which extend longitudinally between the gripped edges of the sheet with air being discharged upwardly through said tubes against the bottom surface of the sheet to form an air bearing support to inhibit sagging of the heated sheet between its gripped longitudinal edges. The apparatus herein is further characterized in that there is a heat interchange between the air and the sheet supporting tubes so that the latter are cooled to avoid possible overheating of the sheet thereabove while the air flowing through the tubes is heated so as not to have undue chilling effect on the regions of the sheet upon which the air jets impinge.
摘要翻译：热成型设备，其中热塑性材料片的相对的纵向边缘部分由分度输送机夹持，该分度输送机将片材输送通过加热炉，其中其被加热到成形温度并通过热成型机，其中加热的片材通过压力和/或真空，所述设备的特征在于，与热成型机相邻的加热炉的长度的至少一部分在其中具有一个或多个多孔管，其在片的夹持边缘之间纵向延伸，空气向上排出通过所述管子抵靠片材的底部表面以形成空气轴承支撑件，以阻止加热的片材在其夹持的纵向边缘之间的下垂。这里的装置的特征还在于，在空气和片材支撑管之间存在热交换，使得后者被冷却以避免在其上方的片材的可能的过热，而流过管的空气被加热，从而不会有不适当的对喷气机撞击的片材的区域产生寒冷的影响。

摘要： CLAIMED IS A PROCESS OF ROTATIONAL MOLDING OF HIGH DENSTIY POLYETHYLENE AND ETHYLENE-POLAR MONOMER POLYBLENDS PRODUCED BY A MELT BLEND TECHNIQUE. SUCH POLYBLENDS HAVE A HIGH DENSITY POLYETHLENE CONTENT OF FROM ABOUT 50 TO 95 PERCENT BY WEIGHT AND AN ETHYLENE-POLAR MONOMER CONTENT OF FROM ABOUT 50 TO 5 PERCENT BY WEIGHT. THESE MELT BLENDED POLYBLENDS SUBSTANTIALLY RETAIN THE BENEFICIAL PROPERTIES OF HIGH DENSITY POLYETHLENE WITH THE ETHYLENE-POLAR MONOMER ENHANCING THE STRESSCRACK RESISTANCE AND, UNEXPECTADELY, THEIR IMPROVED STRESSCRACK RESISTANCE IS RETAINED IN ROTATIONAL MOLD PROCESSING OF THE BLENDS.
