Patent number: 7507026Abstract: Systems, methods and devices for implementing automatic control of focal spot Z axis positioning are disclosed for use with an x-ray device having an x-ray tube positioned within a housing and configured for thermal communication with a temperature control system. Control circuitry, and a position sensing device configured to determine the distance between the focal spot and a reference point related to the x-ray device, are coupled with a control module. The position sensing device sends information concerning the relative distance between the focal spot and the reference point to the control module which compares the received information with a predetermined desired distance. If the received information varies by an unacceptably large margin from the desired distance, the control module sends a corresponding signal to the control circuitry which causes the temperature control system to implement an appropriate change to a heat transfer parameter associated with the x-ray device.Type: GrantFiled: October 22, 2007Date of Patent: March 24, 2009Assignee: Varian Medical Systems, Inc.Inventors: Gregory C.

Patent number: 7302042Abstract: A system for remotely venting an expansion bladder employed in a liquid-filled container, such as an outer housing of an x-ray tube. The remote venting configuration provides the expansion bladder with access to atmospheric pressure existing about the x-ray tube so as to enable it to compensate for pressure changes within the liquid-filled container that occur as a result of liquid heating. Further, the remote nature of the bladder venting system enables the expansion bladder to be positioned within a portion of the outer housing that is radiation shielded, while the remote venting portion of the system is positioned in an unshielded portion of the housing. This eliminates the need to perforate the radiation shielding of the outer housing in order to provide atmospheric pressure to the bladder. Further, the remote vent is semi-permeable so as to prevent liquid escape from the system in the event of bladder rupture.Type: GrantFiled: April 28, 2006Date of Patent: November 27, 2007Assignee: Varian Medical Systems Technologies, Inc.Inventors: Wayne Rollins Hansen, Ricky Smith

Patent number: 7150562Abstract: A cable terminal and clamp system particularly suited for use in an x-ray tube environment. The cable terminal and clamp system includes a cable socket having cable and terminal ports, each of which defines an axis. The cable terminal and clamp system includes a cable clamp that receives at least a portion of the cable socket. The cable clamp and cable socket are configured so that motion of the cable socket, relative to the cable clamp, along the axis defined by the terminal port is unimpaired, while motion of the cable socket, relative to the cable clamp, along the axis defined by the cable port is precluded. A spring interposed between the cable socket and cable clamp biases the cable socket away from the cable clamp along the axis defined by the terminal port. The cable terminal and clamp system thus accommodates thermal expansion of the terminal, while retaining the terminal in an associated receptacle and maintaining alignment of the cable clamp and cable socket.Type: GrantFiled: September 9, 2004Date of Patent: December 19, 2006Assignee: Finisar CorporationInventors: Wayne R.

Publication number: 20060070908Abstract: A stackable container (10) has a generally cylindrical body with a rounded top (12), a rounded bottom (14), and a sidewall (16). A pair of opposed ears (26) formed below the top of the body extend outwardly from the side of the body for attaching ends of a handle (24) used to lift and carry the container. The container has a locking mechanism for stacking the container with a similarly formed container so the containers are securely attached to each other to facilitate their movement. The container has a circumferential lip (18) formed about the top of the container and a pair of opposed notches (30) are formed in the lip. A pair of lugs (32) extend outwardly from the container sidewall and are sized to fit into the notch when two containers are stacked together so to attach the containers to each other and facilitate stacking of the containers. In one embodiment the notches and lugs are aligned with the respective ears; while in another embodiment they are offset from the ears.Type: ApplicationFiled: October 6, 2004Publication date: April 6, 2006Inventors: Rodolfo Raymundo, Ricky Smith
