  • Patent number: 10414086
    Abstract: 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.

  • Patent number: 9689669
    Abstract: System and method for sensor alignment. In one example, a reimaging optical system includes reimaging foreoptics positioned to receive and reimage incident electromagnetic radiation to produce an intermediate image plane and output an optical beam of the received incident electromagnetic radiation, an imaging optical apparatus positioned to receive the optical beam and focus the electromagnetic radiation of the optical beam onto a first focal plane, a first imaging sensor positioned at the first focal plane and configured to produce a first image responsive to receiving the electromagnetic radiation of the optical beam, an alignment object selectively positioned at the intermediate image plane and configured to superimpose an alignment tool upon the first image, and a controller coupled to the first imaging sensor and configured to perform an alignment process for the first imaging sensor based on at least a position of the alignment tool in the first image.

  • Patent number: 5522670
    Abstract: 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. The translatable member is adapted for engagement with the second piece of equipment when in the engagement position. A means is provided which is operable from a location away from the body for translating the translatable member between the insertion position and the engagement position.

  • Patent number: 4887805
    Abstract: 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.
