Patent number: 6698258Abstract: A rotating modular arm with two arm segments is used in a cabinet locking system. The two arm segments are urged apart by a spring. Each arm segment is connected to a lock bar. When the modular arm is rotated, the arm segments displace the lock bars to lock or unlock the drawers of the cabinet. One of the arm segments defines an elongated asymmetrical slot with two slot portions. The first slot portion is elongated and has a width that is less than the diameter of the second slot portion. A keyed lock housing includes a rotating lock core attached to a Z-shaped crank. A retainer is securely attached to the crank. The retainer has a diameter that is less than the diameter of the second slot portion, but the retainer diameter is greater than the width of the first slot portion. During installation, the retainer is engaged with the modular arm by first inserting the crank through the second slot portion.Type: GrantFiled: June 12, 2002Date of Patent: March 2, 2004Assignee: Wesko Locks Ltd.Inventor: Florian Westwinkel

Patent number: 6698259Abstract: A lever lock apparatus having a sliding bolt, a detent mechanism for locking the bolt against sliding movement and a plurality of levers. When using the appropriate key, the detent moves to allow the bolt to be slid to a locked or unlocked position. When the lock is under attack, and an inward force is applied to the bolt, the detent moves so as to maintain a detent fence away from the levers. Keeping or moving the fence away from the levers impairs the ability to pick or otherwise attack the lock.Type: GrantFiled: May 24, 2001Date of Patent: March 2, 2004Inventor: Daniel MacMillan

Patent number: 6698261Abstract: A locking cap is selectively locked into place within a tubular opening, such as the open end of a standpipe used to charge a building sprinkler system. The locking cap has an expandable sleeve and a spreader member. As a key is turned, the spreader member is drawn into the expandable sleeve which is urged outward. The outward movement of the expandable sleeve increases a frictional component such that the expandable sleeve becomes frictionally locked within the tubular opening. The key has an end design that is complemented by an end of an actuator shaft such that the likelihood of unauthorized removal of the locking cap is reduced.Type: GrantFiled: October 17, 2002Date of Patent: March 2, 2004Assignee: Knox CompanyInventor: Dohn J.

Patent number: 6698262Abstract: The invention relates to an access system in which an access authorization that can be disposed of outside of the vehicle communicates with identification means located inside the vehicle. If the identification means respond, control means which operate a door lock (40) from a door handle (10) are transferred out of their inoperative position into an operative position. To this end, the door handle (10) can move between three different positions (10.1, 10.2). In the first position, the door handle (10) is located in a retracted position (10.1), which cannot be grasped by the human hand, but rather is streamlined. Only when the door handle (10) is in a protruding extended position (10.2) is the latter possible. The door handle is then manually displaced into a third protracted position in which the door lock (40) is opened. According to the invention, this mode of operation is ensured by an actuator (30) configured, for example, as an eccentric.Type: GrantFiled: August 21, 2002Date of Patent: March 2, 2004Assignee: Huf Hülsbeck & Fürst GmbH & Co.

Patent number: 6698263Abstract: A remote-controlled door lock includes a housing installed inside with a battery base, a circuit board and an electromagnetic valve. The electromagnetic valve is fitted with a lateral valve rod controlled by the circuit board to extend out of the through hole in a sidewall of the housing and engage in the insert hole in a sidewall of the bolt base of a doorjamb. A remote controller is operated to control the valve rod of electromagnetic valve to move outward and extend out of the through hole of the housing and engage in the insert hole of the bolt base to lock the door at a limited position. Thus, the door lock is impossible to be unlocked only by a key before the valve rod of the electromagnetic valve is released by the remote controller to disengage from the insert hole of the bolt base, having best effect of anti-theft.Type: GrantFiled: July 22, 2002Date of Patent: March 2, 2004Inventor: Hui-Hua Hsieh

Patent number: 6698264Abstract: A core assembly for a lock includes a core, a sleeve, and a housing. The core has a keyhole longitudinally defined therein. An elongated slot is defined beside and communicated with the keyhole. Multiple lower lock balls are received in the core and not aligned with the elongated slot. The sleeve is securely provided outside the core. The housing is provided outside the sleeve, and has multiple upper lock balls corresponding to the lower lock balls. The lower lock balls are not accessible directly through the keyhole and the elongated slot, so that it is impossible to unlock the lock by a tool without a correct key, and the lock has a high security.Type: GrantFiled: May 6, 2003Date of Patent: March 2, 2004Inventor: Wan-Chien Liao

Patent number: 6698265Abstract: A preferred method for closely coupling a first and a second necking machine comprises removing an input module from the second necking machine, removing end portions of a bearing support plate and a base of the second necking machine, and fixing a cover plate to the base of the second necking machine. The presently-preferred method also comprises positioning the first and second necking machines end to end so that a drive gear of the discharge module of the first necking machine meshes with a drive gear of the necking module of the second necking machine, and the necking module of the second necking machine is adapted to receive the can body from the discharge module of the first necking machine.Type: GrantFiled: September 6, 2002Date of Patent: March 2, 2004Assignee: Crown Cork & Seal Technologies CorporationInventor: Keith A.

Patent number: 6698266Abstract: A method for controlling a bar processing mill having an exit and a cooling bed to produce bars of a predetermined cold length. The method includes, for a first bar in a processing order, calculating a long hot cut length based, at least in part upon a predetermined cold length. In addition, the method includes adjusting the long hot cut length based on a total length of bar exiting the exit, if the long hot cut length is greater than a minimum cooling bed length, and if a number of layers of bars to be processed on the cooling bed is less than a predetermined number.Type: GrantFiled: March 20, 2001Date of Patent: March 2, 2004Assignee: General Electric CompanyInventor: Mervin W.
