Filed: 1924-11-13
Abstract: 225,208. Zuana, G. D. Nov. 23, 1923, [Convention date]. Hank type. - In machines for mercerizing cotton skeins of the kind having fixed and movable horizontal stretching cylinders, the movable cylinders can be adjusted by hand parallel to themselves to vary their distance from the fixed cylinders and thus adapt the machine for dealing with skeins of different length or to stretch them to a greater or less extent. The movable cylinders are mounted on a shaft 22 carried bv levers 21 connected at each end to horizontal screwed bars 20, 25 pivoted to bell crank levers 17, 26. The screwed bars are operated simultaneously for adjusting the distance between the movable rollers on the shaft 22 and the fixed rollers on the shaft 18 carrying the bell-crank levers 17 by hand wheels 20<1> and chain and sprocket gearing 25<1>, 25<11>. The levers 17 are operated by power driven cams 15 to stretch the fabric during the operation of the machine, the levers 26 being counterweighted at 28 to give a resilient action. The lower ends of the levers 21 have rollers 23 resting on the base of the machine. The fixed rollers on the shaft 18 are driven bv chain gearing to ensure immersion of the hanks in the treating vessels below. The machine is driven by an electric motor 1 through a friction clutch which is thrown out on the completion of the mercerizing operation by a projection on the shaft carrying the cams 15, the clutch being put in to restart the machine by a hand lever.

Title: Installation and process for heat treatment of refuse and/or similar products
IPC: F23G5/16
Filed: 1974-06-19
Abstract: 1471471 Treatment of refuse LAURENT BOUILLET SA 19 June 1974 [20 June 1973 29 May 1974] 27192/74 Heading F4B An installation for heat treatment of refuse or similar products has a combustion chamber 10 comprising a cylindrical part 12, a truncated conical part 15 and an end cylindrical part 16. The part 12 has an inlet in the end 13 for refuse from the passage 41 and an exhaust gas opening 70 that is covered by an externally mounted gas collection hood 71. The chamber 10 has an oscillating movement around its longitudinal axis to propel refuse through the chamber. The chamber refractory lining is composed of tiles 81 separated from the casing 80 by studs (83), Fig. 7 (not shown), to form the space 82. Passages 88 which may have individual shutters (85), Fig. 5 (not shown), control the amount of combustion air entering the chamber from the space 82. Air supply into and out of the space 82 is via the passage 90 which is integral with the chamber casing. Combustion gases from the chamber 10 may flow in two directions to a post combustion chamber 21, one flow via the outlet 70 and the other via the intermediate portion 58. The amount flowing in either direction can be controlled by a shutter 96. Apart from solid waste entering via the passage 41, sludges from bins 44 and 45 and liquid from the tanks 52 and 53 can be fed to the installation at various points depending on the calorific value of the waste product. Ash is removed from the installation at the points 17, 23 and 107 and is carried away on conveyers 108 and 109. Fuel from the tank 61 may be injected into the installation at 59 for heating the combustion chamber 10 and at 104 for heating the post combustion chamber 21. The chemical composition of the exhaust gases may be controlled by the introduction of treatment compounds at the points 106 and 75. In a modified version of the installation the intermediate portion 58 is dispensed with and exhaust gases from the outlet 70 are fed direct to the post combustion chamber 21 (Fig. 10). In a further arrangement a wind-box (180), Fig. 11 (not shown), with a shield (184) and lever (185) is arranged to control the combustive air injected into the refuse. With this arrangement some air can be used for combustion and some drawn off by the valve (191) for other purposes.

Abstract: 1,044,606. Capacitors. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 30, 1965 [June 30, 1964], No. 27643/65. Heading H1M. In the manufacture of the multi-layer capacitor shown, a layer 11 and two relatively small masses 12 and 13 of anodisable metal, e.g. tantalum, niobium, zirconium, titanium, hafnium and aluminium are deposited by cathodic sputtering on a glass or other refractory substrate 14. An oxide layer 15 is formed on layer 11 by anodising, masses 12 and 13 being masked. Counter-electrode 16, of nickel, gold, silver, tin, lead or copper, is applied by vapour deposition to the oxide layer and covers now unmasked portions of the masses 12 and 13. An insulating covering 17 of e.g. silicon monoxide or dioxide is vapour deposited on to layer 16 and portions of masses 12 and 13. When a second layer 18 of anodisable metal, deposited on layer 17 by cathodic sputtering, is subjected to anodising to form oxide layer 19, the anodization voltage which otherwise might have led to breakdown of the first dielectric layer, now results in the formation of oxide layers 20 and 21 on the exposed surfaces of masses 12 and 13. Conductive films 23 and 24 are deposited by cathodic sputtering to penetrate films 20 and 21 and make electrical contact with masses 12 and 13, thereby connecting electrode 16 to subsequently vacuum deposited electrode 22. Finally second insulating covering 25 is applied.

Title: Improvements in or relating to the manufacture of ammonium salts
IPC: C01B17/64
Filed: 1952-11-03
Abstract: <PICT:0718675/III/1> In the process of making ammonium sulphate and ammonium thiosulphate, by contacting a continuous current of aqueous ammonia containing hydrogen sulphide with a continuous current of free oxygen-containing gases, preferably air, at elevated temperature, said gaseous oxidizing agents being caused to move freely upwards in finely divided condition through a coherent column of said ammonia water, evaporating the liquid containing ammonium salts and recovering solid ammonium salts, said contacting is carried out under superatmospheric pressure, preferably 20-30 atmospheres when air is employed as oxidizing agent.  Preferably the process is performed in several stages connected in series in which in each stage the reactants move in co-current whereas with respect to the entire system stages the reactants move in counter current, and substantially ammonium thiosulphate solution is produced in the first stage.  It is desirable to commence with an almost saturated solution, so that a highly concentrated solution may be removed, thereby reducing the cost of evaporation.  Catalysts such as salts of heavy metals, e.g. copper, cobalt or nickel may be used and fine-grained active carbon may be used as a promoter.  Excess ammonia, if present, may be recovered.  In the preferred embodiment, reactors such as that shown in Fig. 1 are used.  The ammonia liquid is fed into interconnected vertical tubes 1 and compressed air is passed in through porous ceramic plugs 2.  A mixture of liquid and gas is withdrawn at 9, separated, and if desired passed to additional reactors.  A jacket 3 surrounds the tubes and is used to supply heating water or steam at the commencement of the process and to remove heat by functioning as a boiler when the reaction is proceeding normally, e.g. at 150-160 DEG C.  The steam so produced may be used to evaporate the solution withdrawn after reaction. Examples with full operating details are given.  Specification 670,847 is referred to.

Abstract: 279,455. Standard Telephones & Cables, Ltd., (Assignees of Bjornson, B. G.). Oct. 19, 1926, [Convention date]. Two-way repeating systems.-In systems in which a relay 5, 30 short circuits one or more of the transmission paths until speech currents come in, the relay is guarded from operation by the comparatively weak disturbances that cause line noise by causing the incoming currents to pass to it over parallel paths including rectifiers 6, 8 or 15, 14 with different saturation currents, the currents in the two paths acting on it differentially. In one arrangement, Fig. 1, the relay has differential windings in the plate circuits of the valves, the valve 8 having a preponderating effect when the line is 'silent. Line noises produce equal effects in both windings and the relay remains in the position shown except for a kick at the beginning of the disturbance due to the retarding effect of a filter 12 in the lower path. In the case of speech however, the relay changes over in response to the strong impulse in the upper path and is not restored when the impulse, weakened by the limiting effect of valve 8, arrives from the lower path. A hang-over relay 25 prevents the end of the syllables from being cut off. In a modification, Fig. 2, the rectifiers act in opposition on a third valve 21 with a simple relay in its plate circuit.
