  • Display apparatus for use in radiography
    Patent number: 4086492
    Abstract: In computerized diagnostic X-ray apparatus data can be provided for a plurality of parallel sectional representations of the body of a patient. If, however, data are required for planes at different orientations in the body it has been usual to realign the body in relation to the apparatus and repeat the examination. It is now proposed to assemble data for inclined planes through the body by reassembly of data for the sections actually examined. The method of achieving this is described, together with a suitable apparatus for the purpose.

  • Slip-ring connection
    Patent number: 4063792
    Abstract: For transfer of electrical energy at high voltage between relatively moving parts it is known to use slip rings and cooperating brushes immersed in insulating liquid. A liquid insulated slip ring connection is described, in which one part is caused to pass through a reservoir of insulating liquid to maintain the insulation without complete immersion and consequent rotating liquid seals. In one example the reservoir itself is formed on the moving part and the liquid is distributed by the forces of rotation.
