IPC: H01F27/14
Abstract: 644,386. Transformers. BRITISH THOMSON-HOUSTON CO., Ltd. June 20,1947, No. 16309. Convention date, March 26, 1945. [Class 38 (ii)] A transformer or other electrical apparatus is enclosed in a hermetically-sealed tank, containing an insulating liquid above which is a gas cushion in free communication with a chemically inert hygroscopic material such as silica gel through which some of the gas of the cushion is forced when changes occur in the ambient or liquid temperature. The silica gel 11 may be mounted in the middle of a housing 12 separated from the main casing 2 and either inside it (Fig. 8, not shown), or outside (Fig. 2). Housing 11 is connected to casing 2 by a tube 15, which may contain a porous material to impede passage of the liquid, movement of gas through the silica gel being facilitated by the space 21 above it. An inspection window 17 and draincock 19 may be provided. In Fig. 6, the silica gel is in a container 24 connected between the main tank 2 and an expansion tank 22. Alternatively the expansion tank 22 may be divided into two parts connected through the dessicator chamber 24, one of the parts being connected to the main tank, Fig. 5 (not shown). A coil for condensing vapour from the insulating liquid and allowing it to run back to the main tank may be connected in the outlet from the main tank. In Fig. 10 the dessicator 12 is connected to the tank 2, directly at one end, and through a condenser coil 39 at the other, whereby the flow of gas is caused by changes in the ambient temperature.

Title: X-ray tube
IPC: H01J35/14
Filed: 1979-03-15
Abstract: An x-ray tube in which the x-ray origin is scanned on a circle around the patient, comprises a ring-shaped anode (8), an electron beam (4) travelling along a circular path being deflected onto the anode at the desired positions. The electron beam path may be in a plane parallel to the anode and perhaps at the same radius. It may be in the same plane as a transmission target/ anode and at a greater radius. The anode should extend over at least 180 DEG  although it may extend to 360 DEG . Electrostatic means (6, 7) may be provided to constrain the beam to the circular path and further electrostatic means (9) (of also Figure 3, not shown) deflect it to the anode of the beam and ensure it is focussed at the point of incidence. Collimators (12, 13) provide a planar fan-shaped beam and the anode may be shaped to attenuate side lobes of the radiation. Electrode (15) collects electrons not deflected. The focal regions may be adjacent or otherwise. Coils may provide periodic focusing to overcome space charge dispersion and dynamic adjustment of the focusing before deflection ensures focusing at target incidence. Focusing may be absent near the deflection region, and current in the coil section near the focal region should be zero. <IMAGE>
