Patent number: 7907753Abstract: A video camera is located at a secure access point and is connected to a computer network. The camera is used as a conventional security camera and also provides automated assistance with access control. When an identity badge is presented to the camera by a person requesting access to the facility, a computer that is monitoring the camera recognizes a bar code or other symbols on the badge and accesses a database to locate information associated with that identity badge. This information is then used to determine if the person should be granted access.Type: GrantFiled: March 8, 2002Date of Patent: March 15, 2011Assignee: Honeywell International Inc.Inventors: Jeremy Craig Wilson, David Black

Patent number: 7607817Abstract: An extruder with a housing comprising parallel, partially inter-engaging bores and screws disposed therein is used when applying a method of feeding powdery bulk materials into such an extruder. A solid transport of powdery bulk material takes place in an inlet zone disposed downstream of a feed opening wherein said inlet zone is partially filled. The inlet zone is provided with at least one gas-permeable wall portion wherein a layer of bulk material is created on said wall portion, thereby preventing bulk material from passing through, The gas-permeable wall portion is connected to a vacuum source and to a pressure gas source. Furthermore, the gas-permeable wall portion has an inner wall which is set back with respect to the wall of the bores, thereby forming a gap with a partially annular cross section wherein a layer of the bulk material is formed in the gap.Type: GrantFiled: March 27, 2008Date of Patent: October 27, 2009Assignee: Coperion GmbHInventors: Hans-Joachim Sämann, Werner Wiedmann, Jürgen Strecker, Peter Heidemeyer, Sören Welb

Patent number: 7517210Abstract: An apparatus for the manufacture of compound pipes with an oval cross-section is equipped with mold halves which advance in a direction of production and of which two at a time combine as a pair on a molding path to form one mold. An injection head of at least one extruder is arranged upstream of the molding path. An external nozzle used for the creation of an external tube is substantially circular in shape and is located at a distance upstream of the molding path. An internal nozzle with a cross-section similar to the oval cross-section of the pipe to be created is located inside the molding path. When entering the molding path, the external tube extruded through the external nozzle is expanded in one direction and pressed together in a direction which is perpendicular to the former.Type: GrantFiled: October 12, 2007Date of Patent: April 14, 2009Inventor: Ralph Peter Hegler

Patent number: 7506574Abstract: A self-tightening retaining system for securing a closure in position closing an access port of a pump housing. The system includes a retaining cover for obstructing removal of the closure from a bore of the access port. The cover has external threads interengageable with screw threads of the bore. A locking device is configured for being secured to the cover such that the locking device rotates together with the cover. The locking device has a fastener receivable in a hole of the closure and has external threads interengageable with threads of the hole. The threads of the cover and the threads of the fastener are spiraled in opposite directions such that when the cover rotates in a loosening direction, the fastener becomes tightened in the hole of the closure thereby stopping the rotation.Type: GrantFiled: March 11, 2004Date of Patent: March 24, 2009Assignee: Gardner Denver, Inc.Inventors: Ernest J.
