Patent number: 6843084Abstract: A security system for a storage container including a latch assembly disposed on an interior side of a door for latching the door in a closed position with the storage container. A plurality of reciprocating latch elements are included in the latch assembly for latching the door in a closed position with the storage container. A latch actuator included in the latch assembly moves the latch elements to latch the door. A master lock assembly controls operation of the latch actuator by having a first locking part of the master lock assembly interlocking with a second locking part carried by an elongated shaft connected to an operator on the container exterior. A tamper-resistant control blocks access to the master lock assembly from outside the storage container whereby access to the container interior is prevented when the latch assembly is closed and the master lock assembly is in an engaged position.Type: GrantFiled: January 22, 2003Date of Patent: January 18, 2005Inventor: Dave Porter

Patent number: 6843085Abstract: A locking and latching system of modular construction in which some of the components of the system are pre-assembled prior to their installation into the structural framework of a vehicle door. The modular construction of the lock and latch system can include the outside and inside door handles, the outside and inside locks, the door latch itself, as well as linkages between these components. The modular components can further facilitate the assembly process by being of a design which simplifies the process of installing them into the structural framework of a vehicle door without requiring the use of specialized tools, thereby reducing the labor costs associated with assembly.Type: GrantFiled: January 28, 2003Date of Patent: January 18, 2005Assignee: Strattec Security CorporationInventor: Steven J. Dimig

Patent number: 6843088Abstract: Apparatus and method for hot blow-forming an article from a blank of sheet metal. Simultaneously, a surface of the blank of sheet metal is formed against a form tool body that partially defines a forming surface and against a form tool insert that also partially defines the forming surface and that is positioned within a recess of the form tool body such that a lateral gap is defined between the form tool insert and form tool body. Opposed projections are provided on upper surfaces of the form tool insert and the form tool body adjacent the gap. The projections create a raised portion on the sheet metal panel that corresponds to the gap. The raised portion is removed flush with respect to a visible surface of the article.Type: GrantFiled: February 13, 2004Date of Patent: January 18, 2005Assignee: General Motors CorporationInventors: Gary A. Kruger, Mark G. Konopnicki, Chongmin Kim

Patent number: 6843089Abstract: The present invention provides a method of embossing or imprinting patterns in the surface of a sheet metal article using superplastic forming at suitable SPF temperatures. A template having a pattern is interposed between a forming tool and a sheet metal blank. Gas pressure is applied to the sheet metal blank. This pressure forces the sheet metal against the surface of the lower forming tool having the template there between. The sheet metal blank is stretch formed according to the contours of the surface of the lower forming press and the template. The embossed and shaped sheet metal part is then removed from the forming tool.Type: GrantFiled: October 23, 2002Date of Patent: January 18, 2005Assignee: General Motors CorporationInventors: Paul Edward Krajewski, George M. Barton, Gary A. Kruger

Patent number: 6843090Abstract: A rolling apparatus is capable of rolling a metal ring to an accurate circumferential length and preventing the metal ring from dropping off. The rolling apparatus includes a metal ring support assembly having tension rollers 2a, 2b for supporting a metal ring W, a rolling roller 5 for rolling the metal ring W, a rolling assembly for pressing the rolling roller 5 against the metal ring W, a tension applying assembly having a tension cylinder 23 engaging tension roller support members 8, 10, 25, on which one of the tension rollers 2b is rotatably supported, for displacing the tension roller 2b to apply tension to the metal ring W, and a rolling processing completing assembly 27 for detecting a completion of rolling of the metal ring W and inactivating the rolling assembly and the tension applying assembly. The rolling assembly has a first resilient member 18 interposed between the rolling cylinder 14 and its piston rod 15.Type: GrantFiled: October 3, 2001Date of Patent: January 18, 2005Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Hideshi Sato, Katsuyuki Nakajima, Yoriyuki Watanabe
