Title: Improvements in sorting devices
IPC: B42F7/00
Filed: 1921-09-23
Abstract: 180,623. Work-Organizer Specialties. Co., Inc., (Assignees of Casey, C. C.). May 23, 1921, [Convention date]. Racks.-A device for sorting papers is formed with light stiff back pieces 1, 2, 3 hinged by flexible strips 4, 5, Fig. 4, so that the back pieces 2, 3 fold over the main back piece 1. Stepped leaves 7, preferably made from a single strip of durable material by doubling it repeatedly upon itself, are attached to the back 1 by alternate folds 8, the other folds carrying binders 9 with indices. The stalls 10 so formed may be indexed. Leaves 11, 13 in a similar manner form stalls 12 on the backs 2, 3 respectively, the levers in either series being of equal length. Owing to the spacing of the inner ends of the leaves 11, 13, these leaves assume a stepped form and in the open position the leaves 13, 11, 7 form a continuous stepped arrangement. In the closed position the leaves 13 overlie the leaves 11, 7, providing a short device. In the form shown in Fig. 3, the back 2 is folded so that the leaves 11 are reverse-stepped. The leaves 7, 11, 13 may be formed from one continuous strip.

Abstract: 729,020. Fluid-pressure servomotor control systems. KROMSCHRODER AKT.-GES., G. Sept. 14, 1953, No. 25283/53. Class 135. An electric switch 4 and a gas supply control valve 1 are both actuated by a diaphragm 2, the latter being subject to the gas inlet pressure in a chamber A and to the pressure in a chamber B which is fed from chamber A through a restriction 3 and from which the gas escapes through a passage t under the control of an auxiliary valve (not shown). The auxiliary valve may be a thermostat, and the gas escaping through passage t may be led away and burned. The point at which the switch operates is adjustable, and an adjustable stop 6 limits the closing movement of the valve.

Title: Process for removing arsenic compounds from phosphoric acid
IPC: C01B25/238
Filed: 1954-08-31
Abstract: 774,709. Purifying phosphoric acid by electrodeposition of arsenic. KNAPSACK-GREISHEIM AKT.-GES. Aug. 31, 1954 [Sept. 2, 1953], No. 25312/54. Class 41. Arsenic is removed from phosphoric acid by electrodeposition in the presence of dissolved copper, which is codeposited with the arsenic, and 0.5 to 50 parts by weight of added iodine per 100 parts of copper, the ratio of copper to arsenic being between 0.2 to 1 and 5 to 1. The copper may be anodically dissolved or it may be added as a soluble salt such as the chloride, bromide, sulphate, nitrate, or acetate, preferably as the phosphate, either directly or as a concentrated aqueous solution. The iodine may be added as a 0.1 N solution or as hydriodic acid or its soluble salts. Cuprous iodide may be used to add both components. Typically electrolysis is effected between a platinum gauze anode 7 and a surrounding copper gauze cathode 8 in a brick-lined double-wall cell 3 heated to 90 C. by liquid passed in the space between the walls, with an applied potential of 3 volts at a low cathode current density the reaction mixture which is stirred being either treated batchwise or passed steadily through the cell from pipe 4 to pipe 5 at a rate so that the reaction mixture is changed every 30 minutes. In the modified cell (not shown) employed in the examples concentric copper gauze cathodes are disposed on opposite sides of the anode.

Title: Process and apparatus for acid reaction
IPC: C07C51/14
Filed: 1959-07-27
Abstract: Acetic acid is prepared from methanol and carbon monoxide and adipic acid from butane diol or tetrahydrofuran, carbon monoxide and water by a catalytic carbonylation carried out at elevated temperature in a reactor the metal or metal alloy walls of which are provided on the inner sides with acid-resistant heat insulating linings which permit access of the reactants to the walls, the latter being externally cooled (see Group III). Continuous processes are described effected under pressure using a mixture of nickel carbonyl and nickel iodide as catalyst.ALSO:<PICT:0878254/III/1> In a chemical reactor a brick acid proof lining limits contact of the reaction material with the reactors metal surface and thermally insulates the inner wall of the reactor from the very hot reaction mass but a space is left between brick and metal to allow some penetration of liquid and thus equalisation of pressures on the two sides of the lining.  A reaction column consists mainly of a pressure metal tube 21, a lower closing flange 22 and an upper closing flange 23.  The reactants are introduced through pipe 24 and the reaction products are withdrawn through pipe 25.  The inner protection of the reaction column is obtained by means of an inner lining, adhering to the inner wall of the metal tube and consisting of refractory bricks 26 mounted by fitting them in each other.  The protection of the lower and upper closing flanges is obtained by means of two sheets 27 and 28, made of the same insulating material, shaped as it appears from Fig. 2.  The metal tube is surrounded by jacket 9, in the hollow space between jacket 9 and tube 21 a cooling fluid is circulated, introduced through 10 and removed through 11.  The outer cooling of both flanges 22 and 23 is assured by circulating the same cooling fluid in two coils 12 and 13 welded on the outer wall of said flanges.  The metal tube 21 and flanges 22 and 23 are entirely made of a Ni/Mo alloy or of titanium or are made of steel and lined inside with a thin thickness of alloy or titanium.

Title: Improvements relating to the control of internal-combustionengines or other prime-movers
IPC: F02D1/08
Filed: 1926-10-15
Abstract: 281,821. British Thomson-Houston Co., Ltd., (General Electric Co.). Oct. 15, 1926. Centrifugal governors.- One or a number of prime movers are controlled by moving the throttle, or by varying the compression of a governor spring 8 step by step through a number of movable devices operated by electro - responsive means. When the electromagnet 27 is energized a spring return slide valve 21 is moved to admit high pressure fluid from a pipe 28 to the bottom of a piston 16 thereby raising the piston rod 31 to raise a cross-bar 32 and thereby raise the lever 33 one step to compress the spring 8. The next step is energizing the electromagnet 26 which acting similarly raises a piston 15 with more travel to further raise the cross-bar 32 and increase the compression on the spring 8. In sequence electromagnets 25, 24 may be operated. with the same result. In controlling a number of prime movers, corresponding electromagnets of each prime mover are electrically coupled together. The prime mover shaft 3 may drive a pump 10 supplying fluid to move the pistons 16 &c. or for other purposes, but compressed air or vacuum means is preferred for moving the piston.

Abstract: 681,373. Rolling; drawing. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Oct. 4, 1950 [Oct. 11, 1949], No. 26078/49. Class 83 (iv). [Also in Group XXXV] In a method of producing sheet or strip material by rolling or drawing through dies, the thickness of the strip is maintained substantially constant by continuous adjustment of the tension applied to the sheet or strip in accordance with variations in the thickness concurrently issuing from the rolls or dies, or the loading on the rolls or dies. In a coldrolling mill 10 for metal strip 24 in which tension is applied to the strip between the unwinding and winding reels 11, 12 the tension is adjusted to maintain the thickness of the strip substantially constant by varying the torque of an electric motor 14 driving the winding reel 12 in accordance with the variations in load on the upper work roll 15. The upper chocks 16 are loaded by screws 18 through interposed steel cylinders 19 having electrical resistance strain gauges 20 on the sides and the motor 14 is controlled through an electronic amplifier 21 supplied with current passing through the strain gauges. In a modification in which a strip is drawn between two dies 31, 33, Fig. 5, the upper die carrier 34 is loaded in the same manner as the upper roll chocks and the drawing tension is similarly controlled.
