Patent number: 10414086Abstract: A method of forming a thermoformed article may include melt extruding polyethylene to form an extruded sheet. The rheological breadth parameter of the polyethylene may change by no more than about 5% after extrusion relative to the rheological breadth parameter of the polyethylene prior to extrusion. The extruded sheet may be thermoformed within a mold to form the thermoformed article. During thermoforming, the extruded sheet may be subjected to solid-state stretching in one or more directions. The thermoformed article may be retrieved from the mold. The polyethylene may have a rheological breadth parameter of from 0.20 to 0.40, a multimodal molecular weight distribution, a polydispersity (Mw/Mn) of from 5 to 18, a density ranging from 0.940 to 0.970 g/cc, may exhibit tensile strain-hardening, or combinations thereof.Type: GrantFiled: May 9, 2016Date of Patent: September 17, 2019Assignee: FINA TECHNOLOGY, INC.Inventors: Michael McLeod, Mahesh Patkar, Jon Tippet, Russell McDonald

Patent number: 5522670Abstract: The invention provides a connector for removably connecting a first piece of equipment to a second piece of equipment. The connector includes a rigid body having a back end and a front end. Means are provided at the back end of the body and are adaptable for slidable engagement in a vertical direction with the first piece of equipment. At least one axially translatable member is provided at the front end of the rigid body, with the translatable member being translatable between an insertion position and engagement position.

Patent number: 4887805Abstract: A top vacuum corrugation feeder employs a vacuum feedhead working in conjunction with an air knife to feed sheets from the top of a stack. The feedhead is valveless and has a vacuum applied thereto during the entire feed cycle in order to increase reliability and decrease minimum feed speed. The air knife includes trapezoidal shaped fluffer jets in front of the stack and side fluffer jets and added on the sides of the stack in order to assist the feedhead in separating severely downcurled sheets for feeding. A rotational damper member is positioned above and has a portion thereof resting on the stack for controlling sheet flutter and leakage of air from the stack sides. A belt coast control member controls the precise stopping position of vacuum belts that surround the vacuum feedhead in order to minimize multifeeding of sheets from the stack.Type: GrantFiled: March 10, 1988Date of Patent: December 19, 1989Assignee: Xerox CorporationInventors: Glenn M. Herbert, Charles S. Kneisel, Russell McDonald, Raymond A. Povio, Michele D. Zirilli
