Abstract: An improved ice cube making and storing system including an ice cube tray, a container for storing and/or serving ice cubes, and a lid for the container. The ice cube tray includes a plurality of separate freezing compartments for forming ice cubes, and incorporates a liquid drain arrangement so that excess water may be removed from the freezing compartments before the tray is transferred to the freezer. The lid may be used as a support for the liquid-filled ice cube tray, to catch any liquid overflow or spillage during filling or transfer to the freezer. The ice cube tray fits directly onto the open end of the ice cube container, so that ice cubes are ejected directly into the container from the tray.
Abstract: Polyethylene terephthalate molding compositions characterized by rapid crystallization are provided by combining polyethylene terephthalate and a filler or reinforcing agent with a crystallization-rate promoter comprising neopentyl dibenzoate.
Abstract: A container with outwardly bowed walls having a removable divider with positioning flanges at its ends which are adapted to mate with similarly shaped surfaces formed in the side walls of the container.

Abstract: A supported high efficiency catalyst component for polyolefin production and methods of making and using the same are disclosed. An enhanced support made from the materials comprising a support base, an inorganic Lewis acid and an electron donor is combined with an active transition metal compound and optionally a second electron donor to form the catalyst component. Additionally, a dehydrating agent may be pre-combined with the support base in the production of the catalyst support. The methods of producing such catalyst supports and catalyst components are performed by milling in the absence of any solvent. Such catalysts produce polymer of such high quality and quantity that polymer extraction and polymer deashing are not necessary.
Abstract: A resin stabilizer composition which essentially contains:(a) an organotin sulfur-containing compound, for example, organotin mercaptides, organotin mercaptoacids,organotin mercaptoacid esters, organotin sulfides, organothiostannoic acids and the like, and(b) an organic over-based complex of Group I or II-a metal bases, for example, barium phenate or sulfonate, an over-based calcium phenate or sulfonate or the like.These compositions remarkably contribute to the long term heat stability of vinyl halide resins. Furthermore, among other advantages, significant economies and synergistic resin heat stabilization are offered by these stabilizer compositions.
