Abstract: The present invention relates to a polyester resin for extrusion blow molded bottles comprising a branched aliphatic glycol and a branching comonomer.

Abstract: An extruder assembly includes a rolling assembly. An extrusion block includes a plurality of extruding ports that receive an extrudable material from the rolling assembly. A regulating mechanism is positioned within, above, or otherwise near each extruding port of the plurality of extruding ports. The regulating mechanism is operable with respect to the rolling assembly to modify a flow of extrudable material through each respective extruding port.

Abstract: A segmenting mechanism includes outer and inner frame members that define a sliding space and an aperture extending therethrough. A first set of sliding blades operates linearly and proximate the aperture. A second set of sliding blades is positioned in an alternating configuration with the first set of sliding blades and also operates linearly within the sliding space proximate the aperture. Each sliding blade of the first and second sets of sliding blades operates cooperatively and simultaneously along each dedicated linear path from a start position, through a medial position to an end position. The start and end positions are each defined by the sliding blades being outside of the aperture to define respective first and second open states of the aperture. The medial position is defined by the sliding blades being at least partially within the aperture to define a closed state of the aperture.

Abstract: An acetal-based composition useful as a nucleating, gelling, thickening or clarifying agent is disclosed. The composition may be synthesized or provided in many different forms, including multicarbon diacetals formed from carbohydrates. Once synthesized, the compound may be employed as an additive in a plastic composition, such as (for example) a polypropylene copolymer. One structure of such an acetal-based composition is provided by the formula: wherein: n is 0, 1 or 2; Ar1 and Ar2 are independently selected from substituted or unsubstituted aryl-containing groups; and R is selected from the group consisting of: alkenyls, alkyls, alkoxy, hydroxyl alkyls, and alkyl-halides.
