Title: Improvements in x-ray apparatus
IPC: G21K1/10
Filed: 1937-01-27
Abstract: 486,460. R÷ntgen-ray apparatus, GROSSMAN, G. Jan. 27, 1937, Nos. 2408, 2409, and 2410. Convention dates, Jan. 27, 1936, March 9, 1936, and March 14, 1936. [Class 98 (i)] Apparatus for the protection of patients from injury by X-rays is characterized by a movable protective filter whose weakening power is continuously or discontinuously variable by movement of the filter produced by an electrical device operated manually or automatically by the X-ray apparatus. As shown in Fig. 1, the effective thickness of the filter 12 is varied by moving it across the diaphragm box 6. The movement is produced by the solenoid 24 attracting the core 22 against the spring 28, and communicated to the filter by racks 14 and 20 and gearing 16, 18. The solenoid is fed from the points 36, 38 on the primary 40, 42 of the main transformer, so that the filter thickness increases with tube voltage. The relay 46 in the primary circuit is of a type which operates the contact 52 when a given number of milliampere minutes of tube current have passed. This operates a relay 56 to open the primary circuit. In Fig. 2, the filter 62 is attached to the circumference of a disc rotated by an electrodynamic device with fixed and rotary coils 72, 74 connected in series. This device may be connected to a transformer tapping, or, as in Fig. 2, to an auto-transformer 80 whose ratio is varied with that of the main transformer. The arrangements of Figs. 1 and 2 may also be operated in accordance with the tube current, e.g. by the voltage developed across a resistance in the tube circuit. Alternatively, two windings may be provided, and operated in accordance with the voltage and current respectively. Fig. 3 shows a fixed filter 88 used with a movable filter 86 of similar taper to equalize the effect over the whole field. In a further arrangement, the voltage to operate the filter is obtained from a manuallyadjusted tap on a regulating transformer connected across the main transformer primary. Its value is registered by a voltmeter calibrated in filter thicknesses. The filter has copper and aluminium parts fixed end to end with an opaque lead portion at the extremity. In another arrangement, to keep the dosage per second constant, the control voltage is derived through an amplifier from an ionization chamber in the path of the rays. Again, a greater or less number of filters of uniform thickness may replace a single filter of variable thiclmess, or a single uniform filter may be rotated about an axis perpendicular to the direction of the rays.
