Filed: 1938-08-12
Abstract: 517,854. Discharge apparatus. GENERAL ELECTRIC CO., Ltd., DONALDSON, D. H., and WRIGHT, D. A. Aug. 12, 1938, Nos. 23813/38 and 16799/39. [Class 39 (i)] In a gas-filled electric discharge device having a sealed envelope of which a considerable part is of metal permeable to hydrogen, such as a steel tank rectifier, hydrogen which accumulates is removed from the envelope by means of tantalum which is heated within the envelope to a high temperature, preferably about 2,000‹ C. The tantalum thus treated absorbs more hydrogen at 20‹ C. than at 600‹ C. The tantalum is preferably in the form of thin wire or strip placed in a side arm of the container which is heated to a temperature above that to which the container is heated during the pumping. After this preliminary removal of deleterious impurities, the tantalum is electrically heated to about 2,000‹ C., for example, for one hour, the evolved hydrogen being meanwhile pumped away. After cooling, the device is ready for use. If the tantalum becomes saturated with hydrogen thereafter, it may be again made active by re-heating. The process may be applied to hot cathode high tension rectifiers.

The invention may be applied to tin-, bismuth- or lanthanumsubstituted PZT with or without any of the usual additives. The measured characteristics of the sample are:- remanent polarization P r , pressure-induced phase transition P h  and bulk density. Thus, P r  may be decreased by adding selected amounts of silicon in the form of a liquid suspension of SiO 2  to the calcined material The value of P h  may be increased by addition of titanium ions in the form of TiO 2  or Pb 2 TiO 3 , or may be decreased by the addition of calcium ions in the form of CaCO 3 . The density may be increased or decreased by respective addition PbO or MgO or Pb ions may be leached out with acetic acid. In detail, the mixture is prepared in the usual manner from oxide powders, precipitates or co-precipitates and calcined at a temperature between 400 and 1100 C. for between 0À1 and 30 hrs. to produce a ferroelectric solid solution. A sample is then prepared by further comminuting, mixing to form an aqueous slurry, pressing, drying and sintering at temperatures between 1100 to 1350 C. to form slugs having 90% theoretical density. From appropriate measurements the amounts of additive necessary to produce the desired characteristics are computed, and mixed with the remainder of the material which is then prepared in the same manner as the sample.

An angular displacement transducer consists of a magnet 12, Fig.3a, movable relative to a sheet 13 of magnetic material which has attached to it one end of a U-shaped member 11 of magnetic material, the other end of which protrudes into an aperture 13a in the sheet 13, so that the flux from the magnet 12 passes almost entirely through the U-shaped member 11 when the magnet 12 is opposite the aperture, and as the magnet 12 moves away from the aperture the flux flow transfers increasingly to the sheet 13, a coil 15 on the U-shaped member serving to detect the flux change, and an intermediate magnetic member 14 being placed between the magnet 12 and the plate. The member 14 may move with the magnet 12. Alternatively both ends of the U-shaped member 11 may be situated in respective apertures Fig.5 (not shown), two magnets (12a, 12b) being provided. The transducer may be incorporated in a gyroscope Fig.6 (not shown) in which the rotor (16) has a magnetic ring (16c) covered with a non- magnetic coating (16b) through which protrudes the magnet (12). As the rotor spins the magnet (12) induces pulses in the coil (15) on the U-shaped member (11), and as the spin axis (16a) rotates the magnetic flux from the magnet 12 shifts from the U-shaped member (11) to the sheet (13) and the pulse magnitude falls. The intermediate magnetic member (14) may have a portion (14a) extending in one direction of spin of the rotor so that the shape of the pulses produced by spin in one direction differ from that of the pulses produced by opposite spin, thereby enabling the direction of spin of the rotor to be determined.

A closed vessel 1 has two flexible diaphragms 4, 4a dividing it into two chambers 2 and 3. Chamber 2 contains an electrolyte such as sulphuric acid or sodium hydroxide, and chamber 3 contains an insulating liquid such as hexane. Electrodes 5 and 5a are provided in chamber 2 and an insulating partition 6 of glass or plastic material, for example, is situated between them. The partition 6 contains a large number of capillary passages 7 each having a central widened portion containing a bead 8 of mercury. The part of vessel 1 forming the chamber 3 has two enlarged portions 9 and 9a with a constriction 12 therebetween. Pairs of contacts 10 and 10a are provided in portions 9 and 9a, respectively, and a bead of mercury 11 fills one of the portions, interconnecting the contacts therein. It is stated that a potential of the order of 1 volt applied between electrodes 5 and 5a will cause the mercury beads 8 to move towards one electrode, dependent upon the polarity and the nature of the electrolyte, and thus exert a differential pressure (via the diaphragms 4 and 4a and the liquid in chamber 3) upon the mercury bead 11, causing it to move into the other enlarged portion and bridge the contacts therein. Reversal of the potential causes the bead 11 to move back again. Deformable parts 13 in the wall of the vessel 1 allow for thermal expansion of the fluids.
