Title: Process for the preparation of pure manganese
IPC: C25C7/00
Filed: 1966-11-01
Abstract: 1,166,106. Electrolytic purification of manganese. UGINE KUHLMANN. Nov. 1, 1966 [Nov. 3, 1965], No.48969/66. Heading C7B. Substantially pure manganese is prepared by refining an impure manganese alloy electrolytically in a confined atmosphere using a soluble anode of manganese alloy plunged into a molten bath which melts below 600C. and which contains by weight 1-20% manganese chloride, 10-59% NaCl and/or LICl, 40-70% CaCl 2 and/or BaCl 2 , 0-10% KCland 0-20% AlCl 3 , passing through the bath an electric current of 1-100 amp/dm<SP>2</SP> at a voltage of 0À1-3 volts. until at least a portion of the manganese from the anode has been deposited on the cathode, removing the cathode from the bath and draining off a portion of the remaining melt salts back into the electrolytic cell, cooling the cathode in free air, and separating the substantially pure manganese deposited on the cathode from the remainder of the salts collected on the cathode. The soluble anode used may be of ferro-manganese or carburized manganese. To recover the manganese from the salt magma present on the cathode first the salts of the magma and metal and then the manganese is melted under a protective layer of the melted salts and cast into a mould under the protective layer. The apparatus shown comprises a cylindrical cell 1 of mild steel, an external casing 2 of refractory insulating metal, an anodic assembly 5 comprising a number of cylindrical baskets 6 of perforated sheet containing the impure metal to be refined, a cathode which may be formed by a solid cylinder, hollow rod, a ribbed section, or multiple rods electrically and mechanically connected together, and as shown includes a disc 17 at its lower part to collect manganese crystals which become separated from the cathodic deposit. The anode assembly is supported from a flange 7 positioned between the lid 8 and cell flange 20 and separated therefrom by gaskets 10. An intermediary cell bottom 15 formed of perforated sheet backed by fine mesh screen may be removed from the cell by means of rods 16, to remove sludge and crystals dislodged from the cathode. The bath may be heated by an external heating resistance 3, by a gas or liquid fuel burner 4, or electrical heaters positioned within the bath. Using the latter form of heating the interior of the cell may be coated with ceramic material, e. g. of alumina or silicoalumina compounds. Cooling circuits 14 maintain the gaskets below their decomposition temperature.

Title: Electromagnetically operable devices
IPC: H01H50/04
Filed: 1973-10-30
Abstract: 1438807 Electromagnetic relays INTERNATIONAL STANDARD ELECTRIC CORP 30 Oct 1973 [31 Oct 1972] 50308/73 Heading H1N An electromagnetic relay comprises a core and coil 1, an L-shaped yoke 2 and a U-shaped armature 3 which are arranged on a casing 6, Fig. 1. Arms 32, 33 of the armature are respectively coupled to actuate contact sets 5 via actuating rods associated with a resilient arm 4, the non-operated state of the relay being shown in Fig. 2b. For normal operation the armature pivots about an axis normal to the core and coil 1 and the two arms 32, 33 seat firmly on the yoke 2 when the base 31 of the armature is attracted to the pole face (Fig. 2a, not shown). In the event of a contact set sticking the armature will tilt in the plane of the base 31 about an axis parallel to the core and coil 1, Fig. 3b, after the "healthy" arm has seated, and increased flux in the armature will help to release the stuck contact. The pivot point of the armature is normally formed by the intersection of slanting edges in a widened portion of the base 31, Fig. 1, and this permits the primary pivotal movement about the axis normal to the core and coil as well as allowing secondary pivotal movement (tilt) in the plane of the base 31 about the axis parallel to the core and coil, but the bottom edge may be parallel to the upper edge in which case a profiled groove is cut in the casing 6 to permit tilting and thus provide an improved flux path between the yoke and the armature. A portion 35 may be bent out of the armature base 31 (Fig. 4a, not shown) and given a flat surface 35a parallel to the casing 6 to avoid the armature resting with only a narrow pivot point on the casing.

Abstract: 1293148 Particle spectrometers VARIAN ASSOCIATES 17 Oct 1969 [21 Oct 1968] 51147/69 Heading H1D Apparatus for generating an electric field for trapping charged particles comprises a number of electrically isolated conducting elements, 1, 2 ... 7 for example, arranged to surround the space in which the field is to be generated and a voltage distribution arrangement which, when supplied with A.C. and D.C. voltages, provides appropriate voltages on the elements 1, 2 ... 7 to form the field, the lines of force of which extend through the space to end on respective conducting elements. Each conducting element defines in operation an equipotential line in a surface formed by the boundary of the space and the conducting elements are so arranged that this surface is not one for which the Laplace equation is satisfied for the desired trapping field. The equipotential lines of the field symmetrically intersect a plane to which an axis of symmetry of the space is perpendicular. As shown in Fig. 2, the elements 1, 2 ... 7 are straight, parallel, equispaced wires, forming a square in cross-section, which, when connected through linear voltage divider 12 to A.C.-D.C. source 10, produces the two-dimensional hyperbolic field distribution shown dashed and which may be used as a conventional quadrupole type mass filter. Adjustable capacitors 14 may also be provided to ensure proper division of the A.C. component. The voltages supplied to each element of each of a plurality of symmetrically disposed elements may be in phase and of equal amplitude. In Fig. 3 (not shown) the wires form a circle in transverse cross-section and a hyperbolic field may be formed either (a) with equally spaced wires and a non-linear voltage division or (b) with non-uniform wire spacing and a linear voltage division. A threedimensional trap is shown in Fig. 5 which has a set of circular equally spaced conducting rings 34 which are contiguous to a pair of facing right circular cones and connected to a linear potential divider, as in Fig. 2, to give equipotentials which are hyperboloids of revolution. Fig. 4 shows an arrangement similar to Fig. 5 in which the wires are replaced by concentric wires 36 which terminate to form the enclosed conical region. In a further embodiment, Figs. 6 and 7 (not shown), the rings or cylinders are made contiguous to a pair of facing right elliptical cones.
