Title: Proportioning control system
IPC: B28C7/04
Filed: 1961-05-15
Abstract: 928,104. Electric correspondence control systems. UNITED STATES STEEL CORPORATION. May 15, 1961 [May 16, 1960], No. 17611/61. Class 40 (1). In a cement manufacturing process, the quantity of mixed, powdered cement clinker and gypsum supplied by drag chain feeders to a common conveyer is determined by tachogenerators driven together with the drag chain feeders, and the signals obtained are used to control the quantities of water and other additives to be added to the powder. As shown (Fig. 2), the output from each tachogenerator 24, 25, 26 is indicated on meters 34, 35, 36, each of which is shunted by a resistance combination 37-42, and a proportion of the total signal is fed to a potentiometric controller 46 which measures the total flow of powder and adjusts the sliders 52, 53 of control potentiometers 50, 51 accordingly. The position of slider 52 is compared in a bridge circuit with that of slider 57 of potentiometer 58 attached to the pump stroke positioner shaft 56 of water pump 29. Normally no current passes through a resistor 75 in the bridge diagonal, but when the rate of flow of cement powder alters, a potential appears at slider 83 which is amplified at 80 and causes motor 55 to raise or lower shaft 56, repositioning slider 57 until the bridge is rebalanced, and the required proportionality between water and cement powder is restored.

Patent GB-586062-A (GB)
Title: Improvements in and relating to porous or impregnated metal bodies
IPC: H01G9/042
Filed: 1944-09-15
Abstract: Fine metal filters are formed by rolling into a thin layer an alloy composed of a precious or semi-precious metal and a low boiling-point metal, for example, zinc, and heating the layer in a vacuum to the vaporisation temperature of the low boiling-point metal but below the melting-point of the alloy.  The low boiling-point metal is evaporated, leaving a filter body of fine porous structure.ALSO:A method of making a porous metal body, comprises producing an alloy of one or more solid metals of low boiling-point and one or more metals of higher boiling-point and evaporating the low boiling-point metal or metals to leave a porous body.  The alloy may be shaped to any desired form prior to evaporation; for example, relatively thin alloy layers may be formed by rolling. The alloy may be rolled to a layer not greater than 50 thousandths of an inch thick and then heated to an elevated temperature at which the low boiling-point metal has a substantial vapour pressure.  The temperature is maintained till any desired proportion of the low boiling-point metal has been evaporated. The temperature may be raised as the composition of the alloy changes, and evaporation may be carried out in vacuum or partial vacuum.  The resulting porous body may be impregnated with a metallic or non-metallic material, for instance a lubricant or molten lead.  The Specification refers to the production of bearings by evaporating the low boiling-point metal from an overlay metal comprising a ferrous metal backing and a facing layer of an alloy of one or more of copper, silver, gold, aluminium, platinum and palladium, with zinc or cadmium (see Group XXXIV); the production of electrolytic condenser foil from an alloy of aluminium and zinc or cadmium in foil form (see Group XXXVI), and the production of fine metal filters from thin layers of alloys of precious or semi-precious metals with low boiling-point metals (see Group I).
Patent GB-479265-A (GB)
Title: Improvements in or relating to a method of making sponge rubber
IPC: C08J9/10
Filed: 1937-06-25
Abstract: Sponge rubber is made by dissolving a water soluble gas, e.g carbon dioxide under pressure in a latex or like composition which is stabilized against coagulation by the gas at atmospheric and elevated pressure, reducing the pressure, conveniently to, but not below, atmospheric pressure, whereupon the latex expands to form a foam, and subsequently coagulating the foam.  Examples of suitable pressure for charging the latex with carbon dioxide are from 24 to 100 lb. per sq. in., pressures of 40-50 lb. per sq. in. being entirely satisfactory. In an example a latex composition containing saponin as a stabilizer against coagulation by carbon dioxide and calcium sulphate as a heat sensitizer, was treated with carbon dioxide at about 60 lb. pressure per sq. in. with stirring for 2 1/2 hours.  The latex was drawn from the container through a suitable valve open to the atmosphere, whereby the issuing latex expanded to a foam which was poured into moulds and vulcanized in steam at 3 lb. gauge pressure for one hour. Other gases, e.g. nitrous oxide may be used.

Title: Improvements in or relating to solid-liquid contact systems
IPC: B01J47/10
Filed: 1965-04-27
Abstract: 1,103,280. Continuous solid-liquid contact system; ion exchange. DIAMOND ALKALI CO. 27, April, 1965 [29, April, 1964], No. 17706/65. Headings B1J and B1Q. In a continuous method of contacting liquids with settleable solids, particularly ionexchange resins, the liquid and the solids are passed in opposite directions through one or more mixing-settling stages, each settler discharging solids into a by-pass duct which conveys liquid from an earlier stage to a later stage of the process, the flow in the by-pass duct being so regulated as to maintain a hydraulic balance of the base of the settler thereby preventing entry of liquid from the bypass stream, the liquid being conveyed to the following stage (if any), and the solids from the by-pass to the previous stage (if any) by means of a current of air. In Fig. 2, the chamber 1 of mixer-settler II is fed with solids by pipe 12a from the next following stage and with liquid by pipe 13a from the previous stage. The two streams are mixed by agitator 15 before passing to settling chamber 2 by duct 16. From the top of chamber 2, liquid passes by duct 13b to the following stage, and from the bottom solid passes into duct 14a which carries a stream of liquid from mixer-settler I via by-pass duct 14b and valve 18. Valve 18 is so controlled automatically by unit 21 (consisting of a light 20 and a photocell 19) that as the proportion of solid in duct 14a rises and hence less light is transmitted, valve 18 admits more liquid into duct 14a, thereby maintaining such a hydraulic balance that only solids pass from chamber 2 into duct 14a, From the end of duct 14a, a source of air pressure is provided to carry the stream by duct 12b to chamber 1 of mixer-settler unit I. Systems according to the invention are described in which the settleable solids are cationexchange resins used for the extraction of metal values from solutions, as for instance copper from mine drainage solutions.

Title: Improvements in or relating to the process of producing ammonium sulphate from cyanogen compounds produced in the distillation of coal or organic substances
IPC: C01C1/245
Filed: 1920-06-30
Abstract: 145,696. Collin Akt.-Ges. zur Verwertung von Brennstoffen und Metallen, F. J. May 17, 1919, [Convention date]. Ammonium sulphate.-Gases containing cyanogen or hydrocyanic acid are treated, after the separation of ammonia, with steam and sulphuric acid to convert the cyanogen into ammonium sulphate. In the case of gases containing a high percentage of cyanogen, such as gas produced by the carbonization of beet waste, after the absorption of the ammonia, and the addition of steam, the gases are passed by an inlet 1 into an apparatus containing bell chambers 2, 3, 4, 5, 6 and baffles 11 and issue at 12. Sulphuric acid enters at 7 and issues at 13, and steam for heating enters at 9 and leaves at 10. When the gases contain a small quantity of cyanogen compounds, they may be washed with water and the ammonia liquor obtained distilled, the vapours being then washed with acid to remove ammonia and then treated as above descrbed. The vapours from the distilling column may be used for heating the apparatus before entering the saturator, as shown in Figs. 2 and 3. In Fig. 2 the ammoniacal vapours enter at 14, pass through the jacket 8, and thence by a connexion 15 pass to the saturator. The gases leave the saturator at 17 and pass by the inlet 18 through the bell-chambers 2, 3, 4, 5, 6 and escape at 12. Sulphuric acid is supplied at 7 and is fed to the saturator by way of a connexion 19. In Fig. 3 the bell-chamber apparatus is shown arranged inside the saturator. The presence of sulphuretted hydrogen in the gas mixture facilitates the conversion of cyanogen into ammonia, and this gas may be added if not already present. Specification 5898/84 is referred to.

Title: An improved method of and apparatus for sealing bags or like containers
IPC: B29C65/18
Filed: 1939-06-20
Abstract: 530,845. Closing bags. JACKSON, L. MELLERSH-. (Kellogg Co.). June 20, 1939, No. 17995. [Class 94 (i)] In the closing of waxed bags or liners for cartons, the opposed surfaces of the upper portions of the walls are heated and pressed together and then mechanically interlocked by deformation and cooled. The deformation may involve. indenting each wall in opposite directions to form alternate depressions and projections in one wall co-operating with corresponding projections and depressions in the other wall to prevent slipping or disengagement during subsequent operations such as the folding down of the sealed surfaces to permit closing of the carton. The carton 1, Fig. 2, is fed into the machine by a belt, between guides 3, rods 5 holding the flaps 4 in the open position. The upper portion of the liner 2 comes between irons 6, one or both of which may be heated, which move towards each other and flatten and seal the top of the liner. The transverse movements of the irons are accomplished by means of rocking levers 25 and links 24 connected to a carriage 12 sliding on rods 13. The irons are also adapted to move longitudinally so as to accompany the carton in its travel. This is accomplished by means of racks 14, 18 co-operating with pinions 15. The rack 14 is fixed to a carriage 9 sliding on longitudinal rods 10, the rack 18 is fixed to the carriage 12 and the pinion is on a sliding block 16. At the next station of work, the top of the liner is engaged between chains 33, Figs. 5 and 6, composed of overlapping links arranged so that a projecting portion on one chain fits into a receding portion between two links on the opposite chain this causing a crimping effect as shown in Fig. 11. The chains are resiliently pressed together by springs 45 acting on movable plates 42 supporting the rear surfaces. Blasts of cold air are projected through apertures 48 in a pipe 47 so that the adhesion of the sealed ends of the liner is ensured. Specifications 218,355, [Class 94 (i)], and 530,846 are referred to.
