Title: Improved Process for the Treatment of Ilmenites or Titanic Iron Ores.
IPC: C22B34/12
Filed: 1917-11-19
Abstract: Titanium iron ores such as ilmenite, if desired after concentration by magnetic separation, are mixed with carbon and an agglutinant such as oil or tar, and heated to a temperature of 900-1100 DEG  C. to reduce the iron.  The friable product is then treated with a dilute acid such as sulphuric or hydrochloric acid to dissolve the iron, and the titanium oxide residue is dried or calcined.

Abstract: 385,299. Automatic exchange systems. TCHOUBRITCH, M., 20, Rue de l'Argonne Sucy-en-Brie, Seine-et-Oise, and SOC. NOUVELLE DE CONSTRUCTIONS TELEPHONIQUES BREVETS TCHOUBRITCH DERVAL, 38, Rue du Chateau-des-Rentiers, Paris, both in France. June 13, 1931, No. 17241. [Class 40 (iv).] An operator's, sending equipment comprises a plurality of manually-operated selecting switches A1 .. A7, Fig. 1, one for each digit, a pair of control relays R1, R2, for each switch, and a counting chain a .. j, Fig. 2, under the control of which series of impulses corre ponding to the positions of the switches are successively sent out. In the drawing, the references within circles indicate where conductors in one Figure are continued on the other. Start key S operates motor M and lights lamp v, and the first closure of springs 16 by cam C operates relay p which completes a loop over outgoing conductors 19, 29, locks over circuit 38, 34, 33, 21, 2, and energizes relay o. When the selecting arms of switches A1 .. A7 are set, temporarily-closed contacts B1 .. B7 operate relays R2 which light lamps u1 .. u7, and energize relay r which lights busy lamp x. The closure of key t to initiate impulse transmission energizes relay q which connects relay R1 of the first switch A1 over conductors 32, 17, to springs 16. At the next closure of the springs, relay R1 operates opening the locking circuit of relay p, locking itself over front contacts of relay R2, and transferring the energizing circuit of relay R2 over the selecting arm of switch A1, and one of the leads 15a .. 15j to a back contact of one of the relays a .. j of the counting chain. At the next opening of springs 16, relay p releases transmitting an impulse over conductors 19, 29, and operating relay u which in turn operates the first counting relay a. Relays k, l, m, also operate and remain operated during the digit. At the next closure of springs 16, relay p reoperates, releasing relay o, and at the next opening, relay u also releases so that the second counting relay b operates. Impulsing thus continues with relays o, u, operating and releasing in a cycle, until the counting relay corresponding to the selected digit operates when relays R2, Rl, release and relay p locks. Relays k, l, m release slowly in succession, after which relay R1 of the second switch A2 is operated and the transmission of the remaining digits takes place in similar manner.

Abstract: 1466164 Looms; stopping automatically SULZER BROS Ltd 19 April 1974 [10 Aug 1973] 17268/74 Heading. D1E A stop motion automatically stops the loom in a position of the main shaft when the heald frames are moving relatively slowly, e.g. open shed, the loom is then restarted and automatically stopped at a position effective to remedy a fault, e.g. closed shed. A solenoid 80 operated by a stop motion is operated when a follower 95 is running on a portion 108a of a cam 91 so that a lift 108c causes the loom to stop at the open shed position. The loom is then restarted either manually or automatically and runs until a second lift 108c stops the loom at closed shed position before it has regained full running speed.

Abstract: 939,963. Wire fabrics. BENDIX CORPORATION. May 17, 1960 [June 22, 1959], No. 17398/60. Class 74 (2). [Also in Groups I, XII, XXI, XXII, XXVI, XXVIII and XXXIV] A wire fabric for providing a porous wall structure for filters, bearings, reactor cores, heat exchangers, rocket motors, nozzles, missiles, nose cones, turbine blades afterburners and combustion chambers comprises a layer one wire thick of alternate smooth wires 14, Fig. 1A, and wires 16 with helical protuberances thereon. The wires 16 may be formed by twisting plane-faced wires or may be of stranded cable and are bonded along their entire length to the wires 14. The wires may be of steel, copper, titanium or molybdenum or alloys and the bonding may be effected by (1) direct fusion, (2) fusion after coating with tin, silver, copper, gold, tin-lead alloys or copper-silver alloys, (3) fusion after applying a brazing powder, (4) fusion after applying an easily reductible oxide such as CuO, CuO 2  or AgO, (5) including a fine wire of brazing material in the fabric layer and fusing, (6) by dipping in a molten bath of tin, copper, plastic or other bonding material. The wires may also be of plastic or any other material connectible by fusing, gluing or other suitable means. A figure of revolution may be formed by winding the wires under tension on a suitable former, such as a cylinder, which may afterwards be cut and formed into a flat sheet. If desired, other layers of the fabric may be added to a first layer as in Fig. 2 and a nesting effect may be obtained if the wires 14, 16 are of different diameters, to reduce the porosity of the structure. If desired, however, the layers may be wound of alternately different hands. The fabric may also be bonded to the mandrel upon which it is  wound such as a perforated cylinder 26, Fig. 6, or a fluted cylinder 28, Fig. 7, for added strength and for use as filter elements. The porous fabric cylinder may be further subjected to rolling after heat treatment to compact it further to reduce the porosity. This may be carried out on the mandrel or if the mandrel is ceramic the fabric cylinder may be removed for this operation. A second heat treatment may then be applied.

A metal cup 2, Fig. 4, is made by cold working a blank sheared from round bar stock, comprising confining an end part 2, Fig. 3, of the blank and upsetting the remainder thereof to the diameter required for the cup, and then backwardly extruding the upset blank to form the cup. A blank 2 cut off from round stock of steel or non-ferrous metal and of uniform diameter b, Fig. 3, is inserted in a die and the upper end portion of the blank is upset by a punch 4 whereby an external shoulder 11 is formed on the blank. Concentric drag rings 5 on the end of the punch prevent radial flow of metal. The blank is then transferred into a further die, Fig. 4, and is backwardly extruded by a punch 7 having a tapered nose. An ejector 6 is provided. In this operation the fibres in the metal in the region 3 are bent out laterally to form loops. The blank is then inserted in a further die, Fig. 5, where the lower end thereof is reduced in diameter and a detonator seat 8 is formed. Further deformation of the cup may then take place, Fig. 6 (not shown), after which it is drawn into a cartridge or projectile case. The invention is stated to improve the fibre . structure of the finished cartridge case and thus prevent bursting thereof.

Abstract: 480,946. Cathode ray tubes. KLAT. ZOW, L. June 25, 1936, No. 17630. [Class 39 (i)] For coating a mosaic screen for a cathoderay tube with a metal such as silver after the screen has been assembled in the tube there is arranged at some distance from the screen and in front of it a carrier containing the metal and adapted to be heated so that the metal is evaporated and deposited evenly on the screen. The Figures show tungsten helices 7 mounted on mica supports 8 so as to lie in planes perpendicular to the screen 5 and passing through the edges thereof. The supports 8 are hinged to a mica strut 11 and connected thereto by wires 10a so as to form a collapsable structure which can be passed into the tube and then expanded and held in position by struts 14a sealed to the tube. When it is desired to form a second coating of metal, as in the process described in Specification 458,586, it may be provided by a second set of helices 9 heated independently of the helices 7. The support 8 is so shaped as to screen the portion of the tube through which the image is projected from the metal vapour. Instead of helices the metal may be carried in tungsten grids or on plates heated by eddy currents. In preparing the screen a part of the metal may be evaporated and the performance of the screen tested and then further portions evaporated until a satisfactory result is obtained. After the screen has been coated the tube may be baked at 100-200 C.
