Title: Improvements in and relating to Valve Control Mechanism.
IPC: F16K31/122
Filed: 1918-10-24
Abstract: 134,275. Cole, Marchent, & Morley, Brailsford, R. S., Spooner, W. W., and Brailsford, A. Oct. 24, 1918. Valve-gear. - A valve 5, formed integral on either side with plungers 3, 4 arranged in a closed hydraulic system, is operated from a remote part of the system by the displacement of plungers 10, 11. The plungers may be displaced by a hand-wheel 12 and worm gearing 13. The cross-sectional area of the plungers may be varied as desired. According to the Provisional Specification, other arrangements of valve apparatus are described, and the application to the operation of the valves of internal-combustion engines is referred to. In one arrangement, a cam is caused to move a piston, and this movement is transmitted by liquid pressure to a piston which operates the valve, provision being made for the expansion and adjustment of the liquid in the system. In another modification, specially applicable to valves having a small movement such as the fuel valves of internal-combustion engines, diaphragms are used instead of pistons. In another arrangement, the operating-pistons are prevented from rotation, and they engage with the screwed ends of a shaft rotatable by a hand-wheel. Any springs which may be used in the system are located at the control device. instead of acting directly on the valve. It is also stated that the valve control by the arrangements described may be centralized. Thus, one operating-cam may operate a large number of valves in sequence by arranging a series of pistons radially around a common shaft. By such an arrangement, the reversal of oil, gas, and steam engines may be facilitated.

Title: Method for obtaining a concentrate of titanium dioxide and a concentrate containing metallic iron from raw materials containing titanium and iron
IPC: C22B34/12
Filed: 1957-05-31
Abstract: A method for the production of a concentrate of metallic iron from raw materials containing titanium dioxide and iron oxide, comprises reducing the raw material, if necessary after the addition of phosphorus and/or sulphur, without melting under such conditions that the iron phase after the reduction contains 0.3-5.0 per cent of phosphorus and/or sulphur, grinding the reduced material to a small grain size, and separating the iron material from the titanium material.  The raw materials may be ilmenite and coke mixed with about 3 per cent of red phosphorus, ferrophosphorus, apatite, sodium phosphate, ferric or ferrous sulphate, or iron sulphide which cause the iron, after reduction, to form large brittle particles which can be separated magnetically after grinding.  To improve separation, the iron reduction should be as complete as possible, preferably over 90 per cent, and grinding carried out under non-oxidizing conditions to prevent re-oxidation.  The temperature of reduction should be as high as possible consistent with the charge not melting (1000-1450 DEG C.).  A pre-oxidation treatment may be used to convert ferrous to ferric compounds which are more easily reducible.  If the pre-oxidation is carried out in the presence of alkali salts, the vanadium content is converted to alkali vanadates which are easily extracted by leaching.

Title: Improvements in vacuum electric tube devices
IPC: H01J19/42
Filed: 1928-06-19
Abstract: 320,849. Robinson, E. Y., and Associated Electrical industries, Ltd. June 19, 1928. Vacuum tubes. - A heater for an equipotential cathode, genode, or other electrode consists of a wire core, preferably tungsten or molybdenum, surrounded by a refractory insulating sheath whereon is wound a conducting helix of tungsten, molybdenum, carbon &c. The insulating body may consist of kaolin, either alone or with other material, quartz, magnesium oxide, zirconia or thoria, and may be applied as a slip in successive coats by dipping, painting or spraying, the coated wire then being dried and sintered or vitrified while under tension. Alternatively, the kaolin may be pressed in a mould round the core before or after the application of the first coats, the kaolin being dried to the biscuit condition and removed at the required points. The coating may then be vitrified and the whole cut into lengths. An alternative method of applying a continuous coating is to pass the wire one or more times through a V- groove in a rotary wheel dipping into kaolin slip. Where other refractory materials, such as magnesia, steatiate, zirconia or thoria, are employed agglutinants, such as starch, sugar or gum arabic, may be mixed therewith. In the case of quartz, a tube of this material is drawn down while hot, placed on the wire core and heated. A sheath of magnesium oxide is formed by coating the core with magnesium and heating this in an atmosphere of steam. After the core is coated, the helix is wound thereon either in short lengths or continuously and in a non-inductive manner if desired. Where carbon is employed, a squirted cellulose thread is wound on the sheath and afterwards carbonized. As shown in Fig. 1, a tungsten or molybdenum wire core 4 is provided with an insulating coating <g> on which is wound, whilst the core is under tension, a heater wire 5 in a single or double spiral, the ends being secured by nickel clips 6 and connected to lead-in wires. If desired, the core 4 may act as a return lead for the wire 5. Fig. 2 shows a valve in which such a heating unit is mounted, the anode 16 being carried by wires 12 secured by a clip 13 to the reentrant tube 14 of the pinch 15. Carried by the wires 12 is a glass cross-piece 11 bearing wires 10 by which the grid 17 and cathode 18 are supported, the cathode consisting of a nickel tube coated with a mixture of barium and strontium oxides. Wires 20 are provided at each end of the cathode for supporting and spacing purposes in conjunction with the wires 10 and an insulating plate 19. The wire, core 4 of the heater is supported at its upper end by a wire 22 carried by a glass bead 21 supported from the wires 12, a spring tensioning-support 23 being situated between the core 4 and the wire 22. The wire 5 is connected at its lower end to a lead-in by a wire 25 and at its upper end to a wire 22a connected to a lead-in wire 26. Specifications 243,868 and 297,966 are referred to.

Abstract: 1313768 Separating entrained garbage from air streams CENTRALSUG AB 14 April 1970 [18 April 1969] 17784/70 Headings BIT and B2P  Domestic garbage entrained in an air stream is removed therefrom by drawing the air inwards through apertures defined between axial blades 11 forming the periphery of a drum 10 rotated fast enough (over 300 r.p.m.) to prevent passage of solid particles. Light material rejected by the drum is then guided or falls to a garbage outlet without being reentrained by incoming air, while heavy material can fall to the outlet in some embodiments without approaching the drum. The drum is enclosed either in a container 1 or in a side chamber thereof, having an inlet 2 and respective upper and lower outlets 3 and 4 for air and garbage, outlet 4 being provided with valves (not shown) whereby garbage is removed without breaking the vacuum prevailing in container 1. In Fig. 1 (not shown) the drum rotates about a horizontal axis in a side chamber (12). In Fig. 2 (not shown) the drum axis is vertical, inlet 2 opens tangentially into chamber (13) wherein the drum is mounted, and a back passage (14) connects inlet 2 direct to container 1 to prevent excess pressure buildup. In Figs. 3 and 4 (not shown) drums 10 rotate about horizontal axes in the top of container 1, the baffle (16) in Fig. 4 defining a downward path for light solids, enabling them to be collected separately from heavy solids which fall directly from inlet 2 to outlet 4. Figs. 5, 6 (not shown) illustrate separators with two drums rotating in opposite directions about parallel axes. The container in Fig. 5 has a tangential inlet 2 below the drums, while Fig. 6 has a downwardly directed inlet between the drums. The drums 10 in Fig. 7 (not shown) rotate about a common axis, their open ends communicating with outlet 3 via chamber (20). The sides of the drums nearest inlet 2 move upwards. Figs. 8 to 11 (not shown) illustrate modified drum constructions designed to ensure uniform inward flow along the length of the drum. In Fig. 8 an inner drum 25 has holes whose diameters vary along the axis. In Fig. 9, drum 10 is divided into zones by concentric flared tubes through which air is withdrawn. In Fig. 10 a cylindrical drum 10 is formed by wedge-like, blades 11 so that the apertures therebetween taper axially. In Fig. 11 the blades are uniform but the drum 10 is frusto-conical.

Filed: 1944-09-20
Abstract: 580,393. Signalling over power circuits. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., SAVILLE, W. and ROSEBY, P. N. Sept. 20, 1944, No. 17915. [Class 40 (iv)] [Also in Group XXXV] In a system for signalling over power lines in which the signal voltage is interrupted at characteristic cadences as described in Specification 525,840, [Group XXXVIII], a preliminary steady injection of the signal voltage is made during which the signal voltage is varied in accordance with the load on the power line in order to avoid possible interference with neighbouring circuits by high signal voltages. The three-phase signal voltage from generator SFG driven by the motor M1 is injected from leads 14, 15 and 16 into the high tension wires HT1, HT2, HT3 and from the low tension side of the transformer TR voltage is taken off between one phase and earth, via the tuning circuit C1, L1, L2, C2, and rectifier RB to register on the high-low contact voltmeter CV. If the voltage tapped off is too low, RL operates to energize the reversible DC motor M2 so as to decrease the field rheostat FRR of the signal generator SFG. If the tapped voltage is too high, RH operates to turn the motor M2 in the reverse direction. The regulating device is disabled during the transmission of the code signal. Specification 541,553, [Group XXXVIII], also is referred to.
