Abstract: Apparatus and process for shearing long units, such as nuclear fuel bundles, into pieces of predetermined length for further processing. The apparatus comprises a sealable magazine for receiving the bundles, means for urging the bundle forward, a vertical and horizontal gag, or alternately two parallel-acting horizontal gags operated in conjunction with a vertical restraint, for compressing the front portion of the bundle, and a shear blade adjacent to the gags, whereby the nuclear fuel bundle may be urged forward in increments, compressed and sheared into pieces.

Abstract: AN IMPROVED METHOD FOR UNIFORMLY MIXING POLYMER MATERIALS AND ADDITIVES WHEREIN ONE CONSTITUENT MAY BE A LOW VISCOSITY COMPONENT AND THE OTHER A VISCOUS POLYMER MIXED BY PASSAGE THROUGH AN EXTRUDER HAVING THE OVERALL LENGTH COMPRISED OF A FEED ZONE 10-20 PERCENT; A TRANSISTION ZONE 27-40 PERCENT AND A METERING ZONE OF 45-60 PERCENT. WITHIN SAID METERING ZONE THERE ARE 2-6 FLIGHT INTERRUPTIONS, SAID METHOD OF MIXING POLYMERS PRODUCING AN EXTRUDATE WITH A COEFFICIENT OF PARTICLE VARIATION OF LESS THAN 30 PERCENT AND SAID POLYBLENDS AND LOW VISCOSITY MATERIALS INCORPORATED IN POLYMERS BEING BOTH

SUITABLE FOR PIECE DYEING WHEN CONVERTED INTO TEXTILE ARTICLES.
