Title: Monochromatic x-ray generator
IPC: H01J35/18
Filed: 1974-09-03
Abstract: 1478318 X-ray tubes MACHLETT LABORATORIES Inc 3 Sept 1974 [4 Sept 1973] 38530/74 Heading H1D An X-ray generator includes a rotating target 38 of width many times its depth and emitting X-radiation from the side opposite to electron incidence, the target being orientated so that only glancing angle X-rays are emitted through window 26 in opaque housing 24. The increased distance of travel through the inclined target enhances absorption of brehmsstrahlung radiation and improves monochromaticity. Residual soft X-rays may be attenuated by a window filter. The electron beam is incident on the external surface of the target in Fig. 2 (not shown), and the X-rays are orthogonal to the rotating target axis in Fig. 3 (not shown). Emissions are discussed in relation to Figs. 4-6 (not shown) for Ce and Mo. The target may be 10-40 Á thick and at 70-85 degrees to the window. Target 38 may be formed by Rh diffusion at 2500‹ C. into graphite member 30. The graphite matrix allows greater electron penetration and distribution of heat to increase the cooling capacity. Member 30 may be Be, B, C and/or A1 and optionally other low At. No. elements and is thermally conducting for cooling the target. Target 38 may be of one or more elements from At. No. 40 (Zr) to At. No. 46 (Pd), and one or more of the lanthanides (At. Nos. 57 to 71) may be used, with iodine or barium contrasting agents in angiography. Ceria may alternatively be used, and Au and W are also mentioned.

Abstract: 1405357 Electric protective systems MOTODA ELECTRONICS CO Ltd 15 Aug 1973 [21 Aug 1972] 38619/73 Heading H2K A circuit arrangement for detecting disconnection or non-conduction in a slider type potentiometer with its resistor body 11 connected between supply terminals 13, 17 and slider 12 connected to an output terminal 18 has first and second transistors 15, 19 with both their collector emitter paths in series across the terminals 13, 17 and the base of the first transistor 15 connected to terminal 13 through the resistance body 11 with the base of the second transistor 19 connected to the slider 12. Under normal conditions both transistors will conduct but an open circuit in the body 11 renders the transistor 15 non-conductive and a disconnection of the slider 12 from the body 11 renders the transistor 19 non-conductive. A device such as a relay 21 which detects the non- conductive state of either conductor may be in series therewith as shown or in series with the collector-emitter of a further transistor (Fig. 2, not shown) having its base connected to the emitter of the transistor 15 and emitter connected to terminal 17. In order to prevent maximum voltage being applied to terminal 18 when an open circuit fault occurs in the body 11 between the slider 12 and transistor 15 a further transistor 24 is provided and when transistor 15 ceases to conduct transistor 24 conducts to short-circuit terminals 17, 18.

Filed: 1970-08-19
Abstract: 1360608 Measuring thickness electrically DAVEY-LOEWY Ltd 8 July 1971 [19 Aug 1970] 39977/70 Heading G1N Apparatus for determining the lateral profile of strip material by detecting the thickness of the material, which may be strip steel, at points across the width comprises means for causing the material to move under tension along a curved path, and means for detecting changes in the speed of the surface at different points across a line on the curved path as measures of changes in thickness.  As shown the curved path is provided by a roller 13, and each detector comprises a roller 14 provided with magnetic inserts on the periphery which co-operate with a probe 16 associated with a coil 17 to that the output frequency of this coil depends on the speed of roller 14. As the thickness of the strip varies so the speed of the roller 14 varies, and by providing a number of sensors and comparing the phase differences of the outputs a measure of the thickness variation across the strip is obtained. By comparing the number of pulses obtained for 1 revolution of roller 13 when the strip is in position with that obtained with it removed an absolute measure of thickness is obtained. The effect on the profile of a strip passing through a mill may be obtained by using detectors before and after the mill Fig.3 (not shown). The upstream profile P 1  and speed V 1  and the down stream profile P 2  and speed V 2  are obtained. Profile P 1  is modified according to the speed change to give P 1 ' = P 1  V 1 /V 2 , and P 2  is compared with P 1 ' on a display apparatus to show the profile change.
