Patent GB-1364142-A (GB)
Title: Digital rate indicator
IPC: G01D1/02
Filed: 1972-09-14
Abstract: 1364142 Flow rate meter ITT INDUSTRIES Inc 14 Sept 1972 [16 Sept 1971] 42626/72 Headings G4H and G4D Apparatus for providing repeated digital readouts of the average fluid flow during consecutive time intervals is adapted so that the time intervals are of such duration that the reading obtained at the end of each measurement is in desired units, e.g. gallons per hour, and is provided with means for dividing the input to the digital circuitry by an integer, preferably in the range 2-9 and multiplying the output of the time base by the same integer so that the same reading will be obtained, in the event that a longer measurement time is required owing to violent fluctuations in the flow rate. As shown, fluid flowing in shaft 5 is converted at 3 to rotation of a shaft 4 which is coupled magnetically at 7 to a shaft 6 with a toothed wheel 9 attached thereto adapted to cause a light beam to impinge in pulses on a photocell 11. These pulses are shaped at 12, 14 and passed to a counter 17 via a "divide by N" circuit 16. An oscillator 18 provides output pulses also to the counter 17, the interpulse interval defining the measurement interval and being arranged so that the count at 17 is in the desired units. A second "divide by N" circuit 19 is provided between oscilator 18 and counter 17 and a switch 22 is adapted to set both of the circuits 16, 19 to the same desired number N. Thus if the pulses arriving at counter 17 are divided in number by, e.g. 2, then the interval defined by oscillator 18 will be multiplied by two. A storage register 20 is attached to the output of counter 20 and furnishes outputs to a counter display 15 via a decoder 21 and to a BCD output terminal.

Title: Optical windows of high radiant energy transmission for tanks, pressure tanks and simulation chambers
IPC: G01N21/03

Abstract: 1,132,802. Optical elements. HERAEUSSCHOTT QUARZSCHMELZE G. m. b. H. Sept.23, 1966 [Sept.23, 1965], No.42685/66. Heading G2J. An optical window of high radiant energy transmission for pressure tanks and simulation chambers, comprises a quartz plate, the thickness of which is as small as possible in order to reduce the absorption of ultraviolet and infrared radiation, the plate being reinforced by means of a cellular frame connected thereto. The cellular frame takes the form of a perforated quartz plate which is fused to the window plate. The perforated plate may be opaque and a metallic reflecting layer may be applied to the walls of the perforations in the plate. The window plate may be coated with a filter layer which absorbs undesired wavelengths. Lens-like thickenings may be formed on the window plate in the area of the apertures in the frame plate.

Abstract: 1400053 Diaphragm cells for electrolysis ORONZIO DE NORA IMPIANTI ELETTROCHIMICI SpA 18 Sept 1972 [22 Sept 1971 43202/72 Heading C7B An electrolysis cell comprises substantially horizontal cell units stacked one on top of the other and in bi-polar connection with each other. As shown in Fig. 1, an electrolytic cell, e.g. for electrolysis of brine is built up from frames A 1 - A 5 . Each frame (except for the top one) encloses the cathode compartment (comprising a cathode screen D 1 -D 4  and steel bottom plate C 1 -C 3 ) of one cell unit and the anode compartment (comprising an anode I) of the cell unit next below. Each anode is substantially planar, has voids therethrough (e.g. 30-60 % voids), is of valve metal (such as Ti, Ta, Zr, Mo, Nb or W) and has an electrically conductive electrocatalytic coating containing a platinum group metal or a platinum group metal oxide, e.g. one or more oxides of platinum group metals together with other protective oxides, such as oxides of Ti. Anode supports H may be Ti clad Cu. The cathode screens are covered with diaphragms (not shown) of asbestos fibre, paper or cloth. Details of the connection between the cathode of one cell unit and the anode of the next are illustrated in Figs. 1a and 1b (not shown). Frames A 1 -A 5  are of steel but the anode boxes have protective linings G of Ti, Ta, hard rubber or plastics material. There are insulating gaskets F 3  between frames. Brine is supplied through lines J, J 2 , and chlorine is removed at K, K 1 . Details of removal of H 2  and NaOH are illustrated in Figs. 3 and 4 (not shown). Fig. 9 shows a modification where frames 3, which enclose the cathode compartments are of steel and frames 4, which enclose the anode compartments, are of glass fibre reinforced polyester resin. Steel cathode screens 3a are covered by diaphragms 10 and are supported by steel ribs 3c on steel bottom plates 3d. The plates 3d are in contact with Ti or Ta back plates 6 from which anodes 5 are supported. Brine is supplied to the cell units via line 7 and balconies 8. See Fig. 9a (not shown) for details of brine supply and removal of Cl 2 , H 2  and NaOH. In operation pressure is applied to drive anolyte through the diaphragms. This is obtained either by throttling the discharge of Cl 2  or by sucking out the H 2 . Different ways of mounting anodes are illustrated in Figs. 10 and 15 (not shown). Anodes of mesh and of parallel bars are illustrated respectively in Figs 19 and 20 (not shown). The cell stacks are sloped 1 degree or 2 degrees from the horizontal to aid drainage. Fig. 10 (not shown) shows suction nozzles 3b which are used to facilitate deposition of diaphragm material and then closed by caps 3g.

Title: Method of controlling a rock drill and a rock drill so controlle
IPC: E21B7/28
Filed: 1974-10-09
Abstract: 1462708 Boring earth &c TAMPELLA A.B. OY 9 Oct 1974 [9 Oct 1973 1 Oct 1974] 43669/74 Heading E1F A rock drill of the type having a drill bit I with cutting rolls 2 each freely rotatable on an axle transverse to the direction of penetration, eg a raise drill as shown, or a tunnelling drill, has automatic control of the feed force applied to the drill bit so that the rate of penetration of the drill bit reaches its maximum value by changing the feed force in steps of predetermined constant magnitude (but of variable direction, eg increasing or decreasing), and measuring the change in the rate of penetration resulting from each change in the feed force, the change in the feed force being made in the same direction as the preceding change if the rate of penetration increases, and being made in the opposite direction if the rate of penetration decreases. Figure 1 shows a graph of the rate of penetration V against the feed force F. Starting at point 1 the feed force F is increased to point 2 and since this causes an increase in V the feed force is again increased to point 3, and yet again to point 4. Since this causes a decrease in V the feed force is decreased to point 3 and then 2, the feed force then oscillating between points 2 and 4 about the optimum feed force F OPT  at point 3. The automatic control device also controls the speed of rotation of the drill bit so that either (a) the speed of rotation of the bit is held constant, (b) the power supplied for rotation of the bit is held constant, the speed of rotation of the bit being allowed to freely adjust itself, or (c) the total power supplied for feed and rotation is held constant. The control device may also ensure that either the total drilling power or the feed force does not exceed a predetermined value.

Title: An improved process of producing iron concentrates from iron ores of low grade
Inventor: HAYMAN JAMES COLIN
IPC: C21B13/08
Filed: 1964-10-28
Abstract: 1,129,994. Producing iron. G.K.N. STEEL CO. Ltd. Jan. 25, 1966 [oct. 28, 1964], No. 44009/64. Heading C7D. Iron e.g. sponge iron concentrate is produced from low grade ore containing clay by heating the ore under reducing conditions, e.g. at 1300- 1400‹C in a rotary kiln containing a CO atmosphere, to yield metallic iron, followed by cooling with or without wet ball-milling and then separation of the iron from the remaining residue e.g. using magnetic separators. Sufficient lime is added to the ore prior to the reduction heating to transform the SiO 2  and Al 2 O 3  of the clay on heating to dicalcium silicate and calcium aluminates, which fall to powder on subsequent cooling thereby facilitating the separation of the iron concentrate. The lime may be added by blending the crushed ore with powdered limestone, carbon e.g. coke breeze being also added in excess of that required for complete reduction. The separated iron concentrate, fabricated into, briquettes, may be used in a blast furnace (as scrap), an open hearth furnace or a converter.
