Abstract: An X-ray imaging system includes an vacuum tube, which is biased by a high voltage power supply connected to the tube by two shielded cables. The cables collectively have a plurality of conductors which are coupled at one end to the high voltage power supply. The other end of each conductor is coupled to a component of the vacuum tube by a separate inductor. During a voltage breakdown of the vacuum tube, the inductors depress electrical current flow between the anode and the cathode of the tube to reduce the erosion of tube components which results from the discharge. This current is in part due to the energy stored in the cable, which is not depressed by conventional current limiting circuits in the high voltage power supply. Voltage limiting devices connected to the tube prevent ringing in the cables from generating excessively high voltage levels.

Abstract: An X-ray imaging system includes an X-ray tube, which is biased by a high voltage power supply connected to the tube by one or two shielded cables which have a characteristic impedance. The cables are coupled to the X-ray tube by a resistance which is substantially equal to the characteristic impedance when a single cable is used or to twice the characteristic impedance when two cables are used. During a breakdown of the X-ray tube, the resistance depresses electrical current flow between the anode and the cathode of the tube. This current is in part due to the energy stored in the cable, which is not depressed by conventional current limiting circuits in the high voltage power supply.

The guide has an end of an upper arm axially supported on a swivel axis inside the swivel casing, and an end of a lower arm axially supported on the swivel axis inside the support casing. A back column formed between the upper and lower arms guide passes through first and second arcuate cut-out portions provided in the swivel casing and support casing. A cable is passed from the support casing into the swivel casing along the cable guide back column, and moves proportionately to angular movement of the swivel casing.

Abstract: A cable handling system for routing a group of cables to a rotatable hub having an arm extending therefrom has a sleeve which partitions the group of cables into side-by-side subgroups. The sleeve is flexible and allows the cables to slide and flex within it. Forward and rearward straps attach the sleeve to a forward position on the arm and a fixed rearward position to hold the sleeve longitudinally in place and subject it to longitudinal and transverse tension. A cable rotator holds the cables next to the hub where they enter the hub area and allows them to pivot in the plane of rotation of the hub as the hub is rotated but does not allow longitudinal sliding of the cables. In the arm area, rigid longitudinal partitions maintain the subgrouping of the cables and the cables are enclosed on the top and bottom to longitudinally support the cables against buckling and facilitate sliding among the cables.

Abstract: A cable retractor for a computed tomography scanner that is driven with a motor and a belt through two revolutions between clockwise and counterclockwise limits about a horizontal axis. An inner drum is fixed on the scanner for rotation therewith and a stationary outer drum is concentric to the inner drum. Cables are fastened where they enter the outer drum and exit the inner drum on their way to the scanner. A loop is formed in the cable in the circular channel defined by the concentric drums to provide enough cable length for the scanner to make two revolutions. A disk facing the channel is journalled for rotation on the inner drum. Pulleys extend axially from the disk to support the cable loop. The disk is belt driven so its angular motion is a constant fraction of the motion of the scanner whereby the pulleys move at the same rate as the loop to keep it supported as cable is reeled between the drums.
