Publication number: 20150114058Abstract: A rotary locking cylinder includes a housing and a rotor mounted therein. Furthermore, tumblers influencing the combinatorics each have a core pin, a housing pin, and a key channel incorporated into the rotor. The tumblers are arranged in the keyway by inserting the security key. The at least two tumblers are mechanically controlled by the security key so that they are arranged radially in different directions. At least one of the tumblers is pulled against the keyway by the security key for arrangement. Furthermore, the at least one tumbler is struck and arranged by a front key tip of the security key.Type: ApplicationFiled: August 23, 2012Publication date: April 30, 2015Inventor: Ernst Keller

Patent number: 8075690Abstract: An apparatus and method for supporting a substantial center portion of a gas distribution plate is disclosed. At least one support member is capable of engaging and disengaging the diffuser with a mating connection without prohibiting flow of a gas or gases through the diffuser and is designed to provide vertical suspension to a diffuser that is supported at its perimeter, or capable of supporting the diffuser without a perimeter support. In one aspect, the at least one support member is a portion of a gas delivery conduit and in another embodiment is a plurality of support members separated from the gas delivery conduit. The at least one support member is capable of translating vertical lift, or vertical compression to a center area of the diffuser.

Patent number: 7776178Abstract: Stress within a suspension wall for suspending a showerhead in a process chamber is ameliorated by one or more of: (1) Openings in the suspension wall that reduce exposure of the suspension wall to process gas or ambient atmosphere when the chamber lid is opened. (2) A substantially vertical arrangement of one or more rifts in the suspension wall which facilitate horizontal buckling or flexing of the suspension wall. (3) A plurality of suspension walls whose respective central portions are coplanar. (4) A gas sealing skirt that helps protect the suspension wall from direct contact with process gas. The gas sealing skirt is connected to either the chamber wall or the showerhead but is not connected to both.Type: GrantFiled: October 25, 2006Date of Patent: August 17, 2010Assignee: Applied Materials, Inc.Inventor: Ernst Keller

Patent number: 7181937Abstract: The locking cylinder has a basic code which can be changed using at least one change key (17, 17?). A rotor (3) is mounted in a cylinder housing (2a, 2b) and has a keyway (4) into which a shank of a standard key which is provided with control surfaces 18 can be pushed in order to position the tumblers which are arranged in three first rows (A, B, C). Further tumblers have coding elements (13) which are arranged in further bores in the cylinder housing (2a, 2b) in a programming position of the rotor (3). The change key (17, 17?) interacts with three further rows (D, E, F) of tumblers in the programming position, these tumblers being arranged in slides. These further rows (D, E, F) each contain tumblers having coding elements (C). The locking cylinder can be produced with a smaller outside diameter and be installed in a particularly cost-effective manner.Type: GrantFiled: June 15, 2005Date of Patent: February 27, 2007Assignee: Keso AGInventor: Ernst Keller
