Publication number: 20110031643Abstract: To produce a hole in a part (1) made of a thermoplastic composite, the part is locally heated to a plastic forming temperature Tf and the fibres (10) of the composite are progressively moved apart at the same time as the matrix (11) in the plastic state is pushed back radially relative to the axis of the hole, firstly to form a starter hole and then to enlarge the starter hole up to the desired hole dimensions. When the hole has been produced, an operation for sizing the thickness of the part in the hole region is carried out without removal of material because of the excess material pushed back from the hole. A tool having a needle (31), the cross section of which progressively changes between a tapered end (311) suitable for producing the starter hole and a heel (312), is used to produce the hole by the method.Type: ApplicationFiled: January 16, 2009Publication date: February 10, 2011Applicant: HACOMAInventors: Gregory Hache, Christophe Saint Martin

Patent number: 7758330Abstract: For forming a ready-to-bake, endless dough ring, a dough piece is first round kneaded in a round-kneading station and then fermented in a fermenting station. In a pressure station, flattening pressure is exerted on two sides of the dough piece for a flat round piece to produce. After a relaxation interval, an inside hole is punched into the relaxed dough piece in a punching station, with a dough ring being obtained. The individual stations of a corresponding dough treatment system are connected to each other by means of a conveyor. Then secondary fermenting of the shaped dough ring takes place, which is followed by baking of a ring article. The result is an efficient method of forming a ready-to-bake, endless dough ring. Producing the baked ring article can be completely automated.Type: GrantFiled: May 31, 2005Date of Patent: July 20, 2010Assignee: Neuenkirchener Maschinenfabrik Emil Kemper GmbHInventors: Ulrich Peitzmeier, Ulrich Gerhardt

Patent number: 7731878Abstract: A process of forming a microperforated plastic film includes providing a post tool having multiple posts, bringing plastic into contact with the post tool such that the plastic conforms to the shape of the posts, and solidifying the plastic into a solidified plastic film having a plurality of microperforations in the shape of the posts. Another step in the process is displacing any skins formed over the holes after solidifying the plastic. The process may be used to form a film for sound absorption where the posts are shaped and arranged to provide microperforations that provide a particular sound absorption spectrum. In one embodiment, the microperforations each have a narrowest diameter of 20 mils, a narrowest diameter less than a film thickness, and a widest diameter greater than narrowest diameter. The widest diameter may be about 125% or more of the narrowest diameter in an embodiment.Type: GrantFiled: December 17, 2004Date of Patent: June 8, 2010Assignee: 3M Innovative Properties CompanyInventor: Kenneth Brian Wood

Patent number: 7691302Abstract: A disposable cup lid including a body and a mounting portion extending around the periphery of the body. The body defines a suitably shaped clearance area to accommodate a person's nose when drinking the contents of a cup having the lid positioned thereon. The body also defines an enhanced drinking area which is suitably configured to provide a person with a drinking experience more similar to the drinking experience of drinking from an uncovered cup or glass. In one embodiment, the body includes a raised portion which defines a lip engaging front wall and an enhanced drinking area. The enhanced drinking area includes a closure member having an upwardly extending gripping member and a drink-through opening initially covered by the closure member, wherein the drink-through opening is positioned substantially adjacent to the lip engaging front wall. The closure member is movable about a hinge from an initial closed position to an open position.Type: GrantFiled: May 9, 2006Date of Patent: April 6, 2010Assignee: Prairie Packaging, Inc.Inventors: Robert W. Hollis, Weston S. Koennecke, John R. Geer, III

Patent number: 7677879Abstract: An apparatus for docking dough includes a base member, a plurality of protrusions extending from a lower surface of the base member, and a handle secured to an upper surface of the base member. The base member is not flat, but rather has a curvature that enables the apparatus to be rocked from side to side when placed on a surface. Thus, in use, the apparatus is first placed on and manually pressed into a dough, such as an uncooked pizza dough. Then, the apparatus is rocked from side to side by the user to dock the dough, ensuring that dimples or divots are made throughout the dough.Type: GrantFiled: July 22, 2008Date of Patent: March 16, 2010Assignee: Pizza Hut, Inc.Inventors: Todd W. Craig, Stephen D. Voels, Maria V. Brister

The silky feeling side of the web exhibits a pattern of discrete hair-like fibrils, each of the hair-like fibrils being a protruded extension of the web surface and having a side wall defining an open proximal portion and a closed distal portion. The hair-like fibrils exhibit a maximum lateral cross-sectional diameter of between 2 and 5 mils, and an aspect ratio from 1 to 3. Methods and apparatus for making the polymeric web utilize a three-dimensional forming structure having a plurality of protrusions being generally columnar forms having an average aspect ratio of at least about 1.Type: GrantFiled: December 20, 2002Date of Patent: February 2, 2010Assignee: The Procter & Gamble CompanyInventors: Keith Joseph Stone, Brian Francis Gray, Julie Ann O'Neil
