Title: Process for cleaning aluminium
IPC: C23G1/12
Filed: 1921-06-28
Abstract: Aluminium is cleaned at a comparatively high temperature in a bath containing 67-70 per cent of sulphuric acid.  Alkali sulphate and water are added, whereupon on cooling crystallized alum is obtained as a by-product.  As an example a bath contains 700 grams of sulphuric acid and 320 grams of ammonium sulphate to the litre and the cleaning is effected at about 105 DEG  C. for 18-20 minutes. When the bath contains not more than 40-45 per cent of free acid, water is added and alum deposits on cooling. Preferably fresh ammonium sulphate is added to regenerate the bath, which can be used for further cleaning.  The alkali sulphate may be added before or after the cleaning of the aluminium.

Filed: 1917-11-29
Abstract: 129,699. Adams, H. E. F. Goold-, Partington,J. R., and Rideal, E. K. Nov. 29, 1917. Alkali, alkaline-earth, magnesium, copper, zinc, and other nitrates.-In the production of nitrates by absorption of nitrogen oxides (such as the products of the electric-arc oxidation of nitrogen or of the oxidation of ammonia) in solutions or suspensions of alkali, alkaline-earth, copper, zinc, or other compounds, a series of absorption towers or chambers is employed, the gas being passed through until the solution contains only nitrate, and the unabsorbed oxides being oxidized to nitrogen peroxide and led into the next absorption chamber. The apparatus may consist of a number of absorbers a in series, with oxidation chambers c inserted between consecutive chambers having air inlets d; or each chamber may be large enough to provide oxidation space within itself, the chambers c being dispensed. with. The gas is admitted at g and escapes at i, while the absorption liquid is admitted at e and passes from chamber to chamber by pipes f, escaping at the outlet h; or the gas and liquid may travel in the same direction. In a modification, Fig. 2, a number of absorption chambers a are arranged so that any chamber in the liquor has become sufficiently nitrated can be cut out. The gas travels through the chambers in series, and the absorption liquor is fed into. and discharged from. each chamber separately at e and h respectively. Intermediate oxidation chambers may be provided as shown in Fig. 1. Specifications 28614/04, 10867/09, 11274/09, 30502/09, and 9884/10 are referred to.

Patent GB-904426-A (GB)
Title: Cash registers and similar accounting machines
IPC: G06C7/10
Filed: 1961-05-16
Abstract: 904,426. Cash registers. NATIONAL CASH REGISTER CO. May 16, 1961 [May 19, 1960], No. 17719/61. Class 106 (1). A cash register includes mechanism for initiating successive cycles of machine operation so that an amount, entered during the preceding amount-entering operation, is entered repeatedly into the machine as long as a control key alone is held depressed, and mechanism to render this ineffective as soon as any of the amount keys are operated. The machine is of the type described in Specification 792,975. On depression of one of of five control keys 21, a pin 22 on it coacts with a curved cam slot 23 in a release plate 24, to push this plate downwards, rocking a release pawl 26 counterclockwise. This releases a stud 30 of a machine release arm 31 so that the spring-urged arm rotates clockwise on a shaft 32 to initiate a machine cycle. A non-repeat pawl 34 attached by a spring 36 to the release pawl 26, rotates counterclockwise about a shaft 29 so that its end 33 will prevent further machine cycles if a control key is inadvertently retained depressed. When no amount keys 41 are depressed, angular camming surfaces 76 on a control plate 63, are in contact with the pins 22 of the control keys. Depression of one of the control keys will thus shift the plate downwards, or counterclockwise, against a spring 70 so that a notch 66 (Fig. 3), presses against a stud 67 of a lever 68. This lever is rocked counterclockwise about a shaft 71 and, by means of a slot and stud 72, rotates a lever 73 counterclockwise about the shaft 32, so that its ear 74 comes into the path of a surface 75 of the non-repeat pawl 34. This prevents the pawl from dropping into the path of stud 30 so that uninterrupted machine cycles can take place whilst the control key is depressed. At the same time, a surface 79 of the lever 68 engages a stud 80 in an arm 81 free on the shaft 32. This arm is connected to a similar one by two rods 82, 83 and counterclockwise movement of these arms moves the rod into a position where it retains, in ineffective position, the zero stop mechanism for each amount bank. A counting device may be provided for counting the number of repeated operation cycles. The repeat mechanism is rendered inoperative if one of the amount keys 41 is depressed, for a pin 42 on the key engages a camming surface 43 to shift a control plate 44 counterclockwise against a spring 47. This rocks a link 45 clockwise and, via arms 50, 54, 57 and links 59, 60 shifts the plate 63 to the right (Fig. 1). This moves the cam surfaces 76 out of, and surfaces 78 in to, contact with the pins 22 of the control keys. Depression of a control key now shifts the plate 63 further to the right so the downward edge of the notch 66 prevents counterclockwise movement of the lever 68. This retains the arm 73 in an ineffective position and permits normal functioning of the non- repeat pawl 34 and machine release pawl 26 to prevent unintentional machine operation.

Abstract: 1,108,991. Fluid-pressure servomotor system; pure fluid amplifiers. HONEYWELL Inc. April 27, 1965 [April 28, 1964], No. 17725/65. Headings G3H and G3P. A pure fluid system controlling the actuation of jacks on an aircraft comprises a sensor 10, Fig. 2, in the form of a vorten rate sensor which produces a pressure differential in lines 21, 22 proportional to the rate of change of pitch which differential is fed through three pure fluid amplifiers 29, 31, 32. The output from the amplifier 32 is adjustable by a pilot's input transducer 14 and the resulting signal is fed through four pure fluid amplifiers 51-54, the output being fed to act on pistons 76, 77 of a fluid actuator controlling an altitude control surface 85. The amplifiers 51-53 are provided with a nulling adjustment which comprises valves 61, 63 in conduits 60, 62 leading from the power nozzle to the main supply line 25. In Fig.4 (not shown) the pressure differential is fed through conduits (21), (22) to act on a power nozzle (30) to produce an amplified output in channels (35), (36) forming the inputs of the next amplifier. A cross-over (23) out of the plane of channels (35), (36) breaks down boundary layer effects. In a modified amplifier used as the final stage, a centre exhaust channel is provided which acts as a vent passage for the fluid from the power device.

Title: Improvements in and relating to a process of preparing alkali celluloses, and in the preparation of cellulose ethers therefrom
IPC: C08B1/08
Filed: 1923-07-09
Abstract: Alkali-celluloses of low water-content are prepared from watery alkali-celluloses by drying at temperatures below 18 DEG  C., preferably below 10 DEG  C.  It is preferred to carry out the drying in vacuum apparatus provided with cooling means, the material being spread in thin layers or continuously stirred or kneaded; but the drying may also be carried out in the presence of air, for example, in hydrogen or nitrogen.  To hasten drying, a dessicating agent may be employed.  The initial material may be cellulose or a conversion product in which the cellulose has not been degraded too far.  The material may be soaked in a solution containing the correct amount of caustic alkali but an excess of water, and the whole mass subsequently dried; or an excess of alkali solution may be employed, and the mass pressed, centrifuged, &c. before drying, until it contains the correct amount of alkali; or the material may be impregnated with alkali solution, pressed if necessary, and solid caustic alkali added.  The alkali-celluloses obtained are particularly adapted for the manufacture of cellulose ethers, either by a single stage or multi-stage process, the procedure depending on the character of the desired product and on the amount of caustic alkali incorporated with the cellulose.
