Filed: 1967-07-07
Abstract: 1,175,276. X-Ray tubes. CARL ZEISS JENA, VEB. 7 July, 1967, No. 31332/67. Heading H1D. A specimen changer for, e.g., an X-ray spectrograph comprises a removable specimen carrier which, in addition to the specimens, carries an obturating disc for the radiation aperture of the X-ray tube. As shown, a removal disc 23 provided with several circumferentially-arranged specimen containers 25 rests upon a rotatable table 14 actuated by gearing 17, 18, 20 from outside the apparatus. A disc 30, carried by the table, may be rotated to a position above the radiation aperture 8 and urged by solenoid 26 against a gasket 10 to form a hermetic and radiation-tight seal for the tube 1. When the disc is in the operative angular position, a cam 34 attached to the table 14 actuates a pawl 33 which normally prevents the hinged lid 12 of the specimen chamber from being opened. When the lid is rotated about its hinge 13, a bolt 36 is released and is urged by spring 35 to engage an aperture 39 in gear-wheel 20, whereby further movement of the table is prevented. The specimen chamber and the tube are connected to a common pump through valves which enable the specimen chamber to be ventilated without destroying the vacuum in the tube.

[Also in Group XIX] Circuits for use in producing a clock track on a magnetic drum (see Group XIX) comprise a pulse squarer and limiter (Fig. 3A) with optional frequency filtering, and the circuits of Fig. 3B, including blocking oscillators responsive to selected parts of a square-wave input to produce time-spaced signals for a centre-tapped recording head, with optional frequency-division facilities. Fig. 3A shows two doubletriode squarers or limiters 43, 47, a switch 46a when in the lower position bringing in a parallel resonant circuit tuned to 250 kc/s. (the normal clock-pulse rate). In the upper position of switch 46a the circuit operates of 2.5 kc/s. The square-wave may be applied to terminals. 50 and 51 of Fig. 3B; 54 amplifies and inverts the positive parts of the signal differentiated by 52, 53 and uses them to trigger a blocking oscillator 56 which with switch 57 in upper position responds to each signal, and in lower position is set to a longer recovery time (adjustable by 75) to act as a frequency divider. The output of 56 is a 2Á sec. negative pulse at the anode which is passed through amplifier 60 (diodes 61 limit the output pulse) to one of a pair of output valves 62, driving the recording head, and via switch contacts 64a to cathode follower 72 which has a 2Á sec. delay line 73 so that blocking oscillator 56<SP>1</SP> is triggered after 56. The output of 56<SP>1</SP> feeds the other halfwinding of the recording head through similar circuits. For low-frequency operation switch 64 is set to its left-hand position, when the negative part of the differentiated (at 78, 79) input triggers 56<SP>1</SP>, which is switched to the same CR recovery circuit as 56. In this case the 2Á sec. delay of 73 is negligible.
