Title: Improvements in musical stringed instruments with electric relay transmission to a loud speaker
IPC: F42B12/44
Filed: 1931-12-01
Abstract: 393,612. Electrical musical instruments. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin.-(Assignees of Nernst, W.; 16, Neue Wilhelmstrasse, Berlin.) Dec. 1, 1931, No. 33335. Convention date, Dec. 1, 1930. [Class 88 (ii).] To enrich the harmonics, particularly at the centre of the compass of an instrument wherein the mechanical vibrations of strings are directly picked up and converted into electric oscillations which are conducted through an amplifier to a loud-speaker, the microphone (electromagnetic or electrostatic &c.) is placed close to the end of a string as at A, Fig. 1. Further harmonics of the 2n, 4n, 6n ..series may be added by securing the string to an elastic magnetic holder H and placing a second microphone, or the other pole B of a bi-polar microphone, close to the holder. Where the instrument has no soundboard, damping means (additional to the usual dampers 13, Fig. 2), may be provided to produce an effect on the tone character similar to that produced by a soundboard, which damps the harmonics and fundamental unequally. The damping means may consist of porous material 11 (felt, wadding, flannel, cork, &c.), applied at a suitable part of the string to produce the tone of a grand piano. Harmonium tone is restored by removing the damping means 11 pivoted at 10, by means of a lever 1, sliding wedge 2, pivoted wedge 6 and connection 8. The distances of the magnet from the end of the string, or from the string itself, or from the holder, may be adjustable. Single pole magnets are preferably used. To further weaken the fundamental, especially for lower notes, a self inductance may be placed in shunt to the magnet. Specification 354,301 is referred to. The Specification as open to inspection under Sect. 91 contains references to springs for adjusting the pressure of the damping means, and to photo-electric transmission means. These references do not appear in the Specification as. accepted.

Title: Improvements in control system
IPC: G21D3/08
Filed: 1957-10-30
Abstract: 824,145. Turbines. GENERAL ELECTRIC CO. Oct. 30, 1957 [Oct. 31, 1956], No. 33864/57. Class 110 (3). [Also in Group XL (a)] A nuclear reactor supplying steam at two different pressures is controlled by regulating the flow of low-pressure steam in accordance with load changes on a turbine and controlling the high-pressure steam in accordance with the pressure of this steam. The low-pressure steam flows through a pipe 12 from a flash boiler in the reactor 11, the high-pressure steam flowing through a pipe 31. A gradual reduction of load causes a governor 27 to close a valve 13 in the low-pressure steam supply. This reduction in flow of low-pressure steam results in a reduced reactivity and consequently a reduction in pressure of the high-pressure steam. A device 32 sensitive to pressure then reduces the flow of high-pressure steam at 34 and dumps some of the steam at 33. The turbine then slows down and restores the position. When the turbine load is removed suddenly the governor 27 in addition to closing the valve 13 effects partial closure of valve 34 and opening of the dump valve 33. By means of a hand wheel 28 the low-pressure valve 13 may be closed during starting and a further hand wheel may operate on the coupling 26 to select the load speed ratio. In a modification (Fig. 4, not shown) particularly suitable for marine operation the links 17, 39 are directly connected so that the load changes effect immediate actuation of the valves 34 and 33. The reactivity control is an effect of the temperature of the water returning to the reactor after super-cooling, this temperature being lower when the low-pressure steam flow is normal and hence the moderator is denser and the reactivity is higher.

Title: Improvements relating to the treatment of nickel-bearing solutions
IPC: C22B3/28
Filed: 1964-08-19
Abstract: An aqueous Ni solution is purified by extracting metal contaminants with at least one water-insoluble quarternary ammonium chloride, iodide, bromide, nitrite, azide, tungstate or molybdate; primary or secondary amine chloride, iodide, bromide, azide, or thiocyanate; or tertiary amine thiocyanate alone or mixed with the chloride; with or without a quaternary ammonium thiocyanate; preferably in a water-immiscible organic solvent. The amine salt may be formed in situ using free amine.  The quaternary ammonium compound preferably contains at least 2 alkyl chains having 8 or more carbon atoms attached to the N atom.  The primary, secondary, and tertiary amines may have alkyl groups containing 18-22, 12, and 8-10 carbon atoms respectively.  The solvent may be methyl isobutyl ketone, mixed xylenes, e.g. kerosene, and/or alcohols, containing the salts at 0.1-1.25 M concentration, and may be used in amounts of 1 part per 10-20 parts of the Ni solution.  Quaternary ammonium chloride is used to remove Co, Zn, Fe3+, Pb and Cu; the iodide to remove Zn and Pb; and the tungstate or molybdate to remove As.  The organic phase is stripped of impurities by treating with an alkali metal hydroxide, a sulphide, NH3, (NH4)2CO3 or soda ash, and the organic extractant recycled.  The aqueous Ni solution is treated to remove anions (Cl1, Br1 &c.) by adding an amine salt in an organic solvent, treating the resultant organic amine salt solution with alkali, e.g. KOH, NaOH, NH3, (NH4)2CO3 or Na2CO3 to re-extract anions into the aqueous phase, and returning this solution to the first stripping of the organic phase. Alternatively, I1 and Br1 may be removed by precipitation as the cuprous salt.
