Abstract: 559,031. Magnetic tests and measurements. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 9, 1942, No. 14212. Convention date, Oct. 11, 1941. [Class 37] A magnetic gauge comprises a field structure having a plurality of parallel flux paths, which field structure is energized by a permanent magnet which is movable to change the flux distribution between the different paths in accordance with changes in the dimension to be gauged. As shown in Fig. 1 two symmetrical halves 10, 11 of a magnetic field structure are secured in spaced relation by non-magnetic plates 12. The parts 10, 11 have their three polar arms extending towards each other to form upper, lower, and central airgaps 13, 15, 14. Between the gaps 14, 15 is a permanent magnet 16 pivoted at 17, and a weak permanent magnet armature 19 is pivoted in the upper gap 13 and biased to a central position by a spring 20. The armature 19 carries a pointer 21 moving over a scale 22. When the magnet 16 is in the symmetrical position shown in full lines its flux divides equally between the lower parts of the arms 10, 11 and the armature 19 is not deflected. If the magnet 16 is moved to one side as shown in dotted lines a part of its flux passes across the upper gap 13 and causes a deflection of the armature 19 corresponding to an amplification of the movement of the magnet 16. A non-magnetic bar 24 to be gauged may be positioned between the lower end of the magnet 16 and the yoke part 10, with or without a spacing piece 25 of known dimensions. A piece 26 of magnetic material to be gauged is, placed on a base 29, a non- magnetic rod 27 being placed between the test piece 26 and a notched lever 28 secured to the magnet 16. In a modification, Fig. 2, the spring 20 is omitted and the armature biased magnetically. Symmetrical field circuit sections 32, 33 are arranged as shown and a central permanent magnet 34 is pivoted at 35. The armature 36 comprises a piece of sintered oxide polarized across a diameter and pivoted on its cylindrical axis, as described in Specification 463,783, [Group XXXV]. The armature is located in the gap between polepieces 37, 38 and is biased to a central position by the upper polepiece of the magnet 34. This polepiece moves in the gap between polepieces 39, 40, which are slotted so that the upper end of the magnet 34 may enter the recess therein without touching. The piece to be gauged may be positioned at 26 between a base 29 and a non-magnetic rod 27, or non- magnetic test pieces may be positioned between the magnet 34 and either of the sections 32, 33. A spacer rod 44 in the form of a hook may be used to gauge the wall thickness of a pipe 45. A spring 46 may be provided to hold the parts tight against the test piece.

Abstract: 1421545 Alkali metal leak detection VARIAN ASSOCIATES 15 Dec 1972 [16 Dec 1971] 58118/72 Heading G1S Sodium metal leaking from the coolant system of a nuclear reactor encounters a probe comprising a metal cylinder 7, Fig. 2, having a hydrogen permeable diaphragm 8 tight sealed in the end thereof and communicating with a sputter ion pump 3 operating an alarm device. A heater 9 is provided to run the diaphragm hot and truely reflect the concentration of H outside the probe, and a thermocouple 15 controls the heater via a power supply P.S and signal receiver S.R. The diaphragm may be of palladium, iron, nickel, titanium, zirconium, columbium or yttrium. The H is produced when the sodium reacts with a coating over its container or with a water vapour laden air surrounding the container, the coating having H which is replaceable by the sodium. Examples of such coatings include inorganic hydroxides, viz barium hydroxide, many clays (including silicates and oxides), mica, asbestos, or alcohols and phenols. In Fig. 3 the alkali (sodium) metal containing pipe 1 is surrounded by a porous filling 27 of metal turnings coated with barium hydroxide, and the heater 9 is omitted. If the system is such that the temperature of the metal will vary, then the temperature signal transmitted from 18 is analyzed by a compensator 29 which generates a correction of the pressure signal from 3. If the surrounding atmosphere is likely to contain hydrogen, then the coating could contain a hydrogen isotope e.g. barium deuteroxide detectable by connecting the pump 3 to a mass spectrometer.

Abstract: 1380570 Data storage; shift register TOKYO SHIBAURA ELECTRIC CO Ltd 29 Dec 1971 [29 Dec 1970] 60386/71 Heading G4C A circuit made of IGFET's, preferably formed as an LSI, can be used either as a shift register or as a memory. The changeover is effected by applying a pulse C to terminal 12. A switching circuit 1 is connected via a shift register 2 to an inverter 3 acting as a buffer circuit, the inverter 3 having feedback lines 4a, 4b to circuit 1. The circuit 1 comprises a first logic unit comprising N channel type IGFET's 2-5 and a second logic unit comprising P channel type IGFET's 6-9, all the IGFET's being connected in series between a negative voltage - E and earth. Circuit 1 can receive a data input I, a control pulse C and a complement control pulse C at the points shown on Fig. 1. The shift register 2 comprises elements 14-1 to 14-n each comprising a first circuit having two N channel IGFET's, e.g. 17, 18, and two P channel IGFET's, e.g. 19, 20, and a second circuit comprising two N channel and two P channel. IGFET's 21-24, both circuits being connected between voltage- E and earth, IGFET's 18, 19 and 22, 23 forming first and second complementary inverters 25, 27, respectively. A clock pulse # 1  and a complement pulse ## 1 , are applied where shown. The output of the last element 14-n, is connected to inverter 3 comprising an N channel IGFET 32 and a P channel IGFET 33. Operation as shift register.-The N channel IGFET's become conducting when a positive (binary 1) voltage is applied to their gates whereas the P channel IGFET's become conducting when a negative voltage ( - E volts, binary 0) is applied to their gates. When a 1 is applied to input 11 and a pulse C is applied to input 12, IGFET's 2 and 3 conduct and discharge a capacitor Cg, to produce a 0 voltage at output 10. Conversly when a0 is applied to input 11, a1 is produced at output 10. As C is 0, the paths through IGFET's 4, 5, 8, 9 are maintained at OFF regardless of the values of the signals from lines 4a, 4b and a signal applied at input 11 is shifted through register 2 in inverted form by pulses # 1 , ## 1  where it is inverted to its original value in buffer 3. Operation as store.-Here C is 0, hence C is 1 and the paths through IGFET's 4, 5, 8, 9 conduct while the paths through IGFET's 2, 3, 6, 7 do not. Thus the value on input 11 makes no difference and the data already in the register is shifted round continuously until required for read out at point 35. In a modification (Fig. 2, not shown) the switching circuit effectively includes the inverter 25 of Fig. 1 and in another modification (Fig. 3, not shown) another output buffer is provided.
