Patent number: 11555629Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes a discharge section housing forming a chamber, a first opening formed in the discharge section housing such that the chamber is configured to receive an air flow from a blower of the HVAC system via the first opening, and a second opening formed in the discharge section housing such that the second opening is positionally offset to the first opening. The chamber is configured to discharge the air flow through the second opening. The HVAC system also includes a guide extending across the chamber and sloping toward the second opening such that the guide is configured to direct the air flow from the first opening toward the second opening.Type: GrantFiled: February 19, 2020Date of Patent: January 17, 2023Assignee: Johnson Controls Tyco IP Holdings LLPInventors: Sumedh J.

Publication number: 20110305918Abstract: A sheet metal component that is bent from a sheet metal blank includes at least one three-sided corner. Two edges of the three-sided corner are formed by a first bending member of the sheet metal blank bent about a first inner bending radius Ri,1 and a second bending member of the sheet metal blank bent about a second inner bending radius Ri,2, and the third edge of the three-sided corner is formed by a first blank edge of the first bending member and a second blank edge of the second bending member. The sheet metal blank has an internal corner that forms the first blank edge, the second blank edge, and a wedge-like recess that opens in the internal corner.Type: ApplicationFiled: July 13, 2011Publication date: December 15, 2011Applicant: TRUMPF LASER- UND SYSTEMTECHNIK GMBHInventor: Andreas Vogel

Patent number: 4892595Abstract: A mold pin insert for a high quality mold such as an optical quality injection mold for molding intraocular lenses, contact lenses and the like, is fabricated from a high quality rolled steel rod whose impurities are concentrated within a longitudinally extending central region of the rod surrounded by an annular relatively impurity free region. A slug is cut from this relatively impurity free annular region and is then heat treated to the desired hardness and machined and polished to the desired outside diameter to form the pin body. Finally, one end face of the slug is turned to form a mold face of desired shape or contour and to reorient the grains at the face in a circular direction about the longitudinal axes of the body, preferably using a cutting tool which produces a built-up edge before the tool, and the face is polished to finish the pin.Type: GrantFiled: April 30, 1986Date of Patent: January 9, 1990Inventor: Orie E. Holmes

Patent number: 4594295Abstract: A two-part cut sheet metal lamination element wherein one of the two sheet metal parts 1 comprises two outer legs 3 and a middle leg 4, the other sheet metal part 5 comprises a crosslink, the two outer legs of the first sheet metal part and the crosslink of the second sheet metal part are rigidly attached to each other, and the free end of the middle leg 4 interacts with the crosslink of the second sheet metal part by a short projection 10 which prevents movement of the free end of the middle leg with respect to the corresponding crosslink by an engagement produced when the two sheet metal parts are pressed together, said engagement and immobilization resulting from the punched or stamped configurations of the sheet metal parts.Type: GrantFiled: May 18, 1984Date of Patent: June 10, 1986Assignee: Bruno WaasnerInventors: Bruno Waasner, Rolf-Dietrich Waasner

Patent number: 4501031Abstract: A prosthetic joint component which is comprised of a metal retainer and a plastic bearing portion which is molded integrally onto the top surface of the metal retainer. The metal retainer includes a plurality of notches spaced apart from each other around the periphery of the retainer. The notches enable the plastic, during the molding process, to flow through the notches to create a thickness of plastic completely surrounding the upper surface and the peripheral edge of the retainer (or metal base plate) and terminating in a lower plastic rim surface which is flush with the perimeter of the lower surface of the metal base plate, forming a strong mechanical interlock between the metal and plastic portions of the prosthetic joint component.Type: GrantFiled: January 22, 1981Date of Patent: February 26, 1985Assignee: Zimmer, Inc.Inventors: John M. McDaniel, Clayton R. Miller
