Apparatus for measuring aproperty of a dielectric material, e.g. the moisture content of paper, of the type described in Specification 1, 192, 748 is modified by including means to control the reference value according to a function of the frequency of the applied voltage so that for a given range of frequencies the apparatus can provide measurements over a wider range of values of that property (moisture contents) than can the constant phase system. As shown in Fig. 3, the reference signal for the phase differencer 30 is modified by including a low frequency lead network and a high frequency lag network to obtain the operating characteristic #r = g 1  (f) in Fig. 8 (not shown). As shown in Fig. 9, a voltage adjustably proportional to the logarithm of the frequency is added to an adjustable fixed voltage and is compared in a voltage differencer 36 with a voltage # 2  representing the phase shift of the current through the probe with respect to the applied voltage to obtain the operating characteristic # r  = g 2  (f) in Fig. 8 (not shown). The output from the frequency logger 42 is compensated for the temperature of the paper in the manner explained in Specification 1,192, 748.

Title: Zinc sulphide
IPC: C09C1/06
Filed: 1935-11-13
Abstract: In the production of zinc sulphide by reacting hydrogen sulphide with an aqueous solution of zinc sulphate with the formation of dilute sulphuric acid, the latter is reacted with barium sulphide to obtain hydrogen sulphide for re-use and barium sulphate.  Barium sulphide may be regenerated by reducing the barium sulphate, as by heating it with carbon.  The barium sulphide produced may be treated with water and again reacted with the dilute sulphuric acid, with or without partial or complete separation of residue.  When the residue is not separated, the barium sulphate obtained from the action of the sulphuric acid may be separated from other solid matter prior to being reduced again. The precipitation of zinc sulphide may be effected in the apparatus described in Specification 423,343, [Group XII], and the invention be used in connection with the processes described in Specifications 428,986, 435,287, and 439,311.  In addition, in operating the process described in Specification 387,181, any deficiency of hydrogen sulphide may be made good by applying the present process for its production.

Title: Process and Cell for the Production of Manganese of Low Carbon Content by Means of a Fused Electrolytic Bath
IPC: C25C3/30
Filed: 1966-07-14
Abstract: 1,158,547. Electrolytically producing manganese or manganese alloy. UNIVERSITE LIBRE DE BRUXELLES. July 14, 1966 [July 16, 1965; July 5, 1966], No. 31730/66. Heading C7B. Mn or Mn alloy having a carbon content less than or equal to 2À8% by weight is produced by electrolysis of a fused bath in the substantial absence of fluorides, the bath comprising either a ternary system selected from MnO-SiO 2 -CaO, MnO-SiO 2 -MgO, MnO-CaO-MgO, MnO-CaO-Al 2 O 3  and MnO-MgO-Al 2 O 3 , or a system containing at least four components of said ternary systems, one of the components being MnO, the cathode being formed of the metal to be produced, this metal being in the liquid state, and the anode being formed of carbon (e.g. an anode of amorphous carbon, graphite or of the soderberg type). The MnO to be used in the bath may be produced from carbonate ores or from MnO 2 . The bath may be purified from Fe and other metals by a pre-electrolysis. For example, in a two-stage electrolysis process, Fe/Mn is produced in the first stage and Mn in the second. The electrolyte can contain minute additions of BaO, B 2 O 3 , NaF or CaF 2  to reduce the melting temperature or increase the electrical conductivity. The electrolytic production of Mn may be accomplished in three ways (1) by an arc system using 35-60V, (2) by an anode effect system using 20V wherein the anode is dipped in but not moistened by the electrolyte and (3) by a system in which the anode is moistened by the electrolyte using 10V. In producing a Mn based alloy, a metal having an affinity for oxygen less than, equal to, or slightly in excess of that of Mn may be introduced into the electrolytic bath in the form of an oxide so that the metal is co-deposited with the Mn. Metal having a melting point lower than the temperature of the bath may be added directly to the bath to alloy with the electrolytically produced Mn. By the electrolysis it is possible to obtain metal with a C content less than 0À1% and Si content less than 2%. It is possible to produce 99% or more pure Mn. Fig. 4 shows an electrolysis cell comprising a graphite anode 9, a water-cooled Cu tube 10 supplying current to a liquid Mn cathode 13 via a stainless-steel component 18, a carbon free magnesia lining 7', refractory bricks 7, steel outer casing 6, steel lid 19 and stainless steel thermal shield 22. The lid maintains a reducing atmosphere in the cell. Figs. 1 to 3 (not shown) illustrate cells which may be heated by induction coils 1 cooled by water circulation. Fig. 5 (not shown) illustrates a cell which could be used on an industrial scale.

Abstract: 898,973. Making sockets; jointing; bending; shearing. BONHOMME, F. R. Sept. 20, 1960 [Sept. 22, 1959], No. 32278/60. Classes 83 (2) and 83 (4)] A machine for making sockets of the type including a multiplicity of wires stretched inside a cylinder along the generatrices of a hyperboloid of revolution and fixed by their ends bent over the ends of the cylinder and held by rings forced thereover, includes an obliquely grooved mandrel for positioning the wires, means for cutting wires from a supply and means for bending over the ends of the wires. Wire A from a spool 29 is fed by rollers 32, 33, intermittently rotated by rack and pinion means 34, 35, through one of a number of oblique grooves 13 on an extension 11 of a mandrel 10, to abut a stop lever 25. A casing 16 is then moved to the left to cause a cam 27 thereon to swing the lever 25 and partially bend the free end of the wire. Then a push piece 14 in said casing 16 further bends the end of the wire over. A weak spring 19 between the push piece 14 and the casing 16 then compresses, and on continued movement of the easing 16 the mandrel 10 is moved back in a fixed easing 15 compressing a strong spring 18. The part 1a of the other end of the wire A is thus bent at right angles between a ring 3 positioned on a part 37 of the mandrel 10 and the end face 23 of the casing 15. The end faces 24, 23 of the casings 16, 15 then come into contact with the wire to sever it. The same operations may be repeated with every wire after relative rotation of the mandrel 10 or all the wires may be fed and cut together. The ring 3 is then driven over a sleeve 2 positioned on the mandrel extension 11 and then a ring 4 in a similar manner. The ring 4 carries, Fig. 1, a hollow extension 5 to accommodate a conductor 6. A plug-in member 7 on a conductor 9 is adapted to fit into the socket. Specification 863,764 is referred to.
