Title: Improvements in tungsten values extraction and purification process
IPC: C22B3/00
Filed: 1961-05-24
Abstract: Iron/manganese tungstate ores, i.e. ferberite wolframite, and huebnerite are digested with aqueous hydrochloric acid, and molybdenum values extracted with methyl isobutyl ketone.  The methyl isobutyl ketone may be present during the digestion step or may be added subsequently.  The process also purifies tungsten ores from other specified metal values in addition to molybdenum values.  In the Example a ground tungsten ore was digested with 12M hydrochloric acid in the presence of methyl isobutyl ketone, at 80 DEG  to 82 DEG C., the mixture filtered and the tungstic acid in the solid residue dissolved in aqueous ammonia.  The resulting solution was evaporated to produce crystalline ammonium paratungstate.

Title: Improvements in and relating to the brush holders of electric dynamos
IPC: H02K5/14
Filed: 1920-07-07
Abstract: 147,089. Munz, F. April 5, 1919, [Convention date]. Brush-holders; dynamos, regulating. - The brushes of a dynamo are carried in a removable holder which can be mounted on the machine in either of two positions corresponding to the two directions of rotation, thereby ensuring that the leads from the machine always have the correct polarity, as for accumulator charging. The holder consists of an insulating-block 8 in which are embedded the brush-holders respectively connected by metal arms 4, 5 to an inner contact 6 and an outer contact 7 which, as shown in longitudinal section, Fig. 3, extends to both faces of the holder. The charging-lead is attached to the contact 6 by a screw-in plug. By pressing the contact 7 over a split sleeve projecting from the end plate 11 of the dynamo, the brush-holder is held in place with the brush 2 connected to the frame and having, say, a positive polarity when the armature has a counter-clockwise rotation. If the machine has a clockwise rotation, the holder is turned back to front and the other end of the contact 7 is pressed on to the projecting sleeve so that the brush positions on the commutator are reversed, but their polarities are unchanged. The outside of the holder is marked with an arrow and by always mounting it so that the arrow coincides with the direction of rotation of the machine, the operative ensures that the charging-lead has the correct polarity. One end of the field coil is connected to the frame and the other to an insulated spring pin carried by the plate 11 in such a position as to contact with either face of the arm 4, holes being provided in the material 8 on both faces of the holder to allow the pin to enter.

Abstract: 711,971. Load limiting systems. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 5, 1952 [Aug. 15, 1951], No. 19265/51. Class 38(4) A system for restricting the load that can be taken from terminals X, Y supplied from network terminals A, B during peak load or other emergency conditions in the network comprises a thermal switch BM having normally closed contacts E in series with the operating coil of a load-responsive relay Co between terminals A, X, and a further relay Cr responsive to ripple signals which are transmitted continuously through the network during emergency conditions. Under normal conditions the heater Ch of the thermal switch is deenergized due to the normally-open contacts F of relay Cr, but the heating circuit may be prepared at contacts D of relay Co if the load taken from terminals X, Y is sufficiently large. Under emergency conditions, the ripple signal causes contacts F to close and if contacts D are also closed, heater Ch is energized thereby causing contacts E of the thermal switch to open and close intermittently the load circuit until either the load is reduced to a value causing drop out of contacts D, or the transmission of the ripple signal ceases. In a modified arrangement the contacts D control the connection of the ripple signal receiving transformer Cc to the network, the heater Ch being controlled solely by contacts F.

Title: Process for making refractory materials of refractory products and to refractory materials or refractory porducts made thereby
IPC: B28C1/14
Filed: 1973-04-26
Abstract: 1399044 Preparation of porous refractory material HARBISON-WALKER FLIR DE MEXICO SA 26 April 1973 [4 May 1972] 19940/73 Heading C1A A process for making refractory material comprising, wetting the surface of a solid particulate plastics or polymer substrate, mixing the wetted substrate with at least sufficient finely divided refractory material to form a coating thereon comprising substantially abutting particles of refractory material, separating the coated substrate from any excess finely divided refractory material, drying coated substrate to remove the liquid to form a substantially cellular structure. A preferred substrate consists of expanded polystyrene beads of between 4 and 28 mesh Tyler and the wetting is carried out using preferably lignin liquor extract by spraying or mixing. Mixing the wetted beads with the finely divided refractory material (e.g.- 100 mesh Tyler alumina) should be carried out in a blender that does not crush the substrate. As an example one cubic foot of expanded polystyrene beads of about - 8 mesh Tyler, wetted with a lignin liquor extract diluted with water, should be mixed with about 25 1b. of- 100 mesh Tyler alumina in order to form a refractory coating. Excess finely divided refractory material is separated by screening and the coated substrate dried, for example, in air at excess temperature. The coated substrate can then be heated to a temperature sufficient to remove the substrate and to form a sintered ceramic bond between the refractory particles. Refractory products can also be joined by shaping the refractory material before firing.
