Title: Method of producing steel having uniformly distributed nitrogen
IPC: C23C8/26
Filed: 1962-05-22
Abstract: Steel which is free of strong nitride-formers such as chromium, molybdenum and aluminium is given a uniformly distributed content of nitrogen by first heating it in a nitrogenizing atmosphere to produce a nitrogen-rich outer case, and then heating it to a temperature above its recrystallization temperature in a substantially non-nitrogenizing atmosphere to cause diffusion. Nitrogenizing may be carried out in an atmosphere of ammonia, possibly during heating to the final treatment temperature which may be at 1000-1350  DEG F. for 1/2 -\ba3/4 hour. The steel may be treated in the form of open coils.
Patent GB-522298-A (GB)
Title: Improvements in machines for filling bottles and like vessels with carbonated beverages
IPC: B67C3/06
Filed: 1938-12-09
Abstract: 522,298. Bottling. TENNANT, W. J. (Crown Cork & Seal Co., Inc.). Dec. 9, 1938, No. 19733/39. Divided out of 522,229. [Class 125 (ii)] A machine for filling bottles &c. with carbonated, beverages consists of a rotary filling mechanism, a number of filling, heads carried thereby, a. filling valve on each head, a number of valve actuating trips spaced along, the path of travel. of the heads and a device adapted to render one of the trips inoperative when a bottle is not in filling position, the succeeding trips being, so positioned that they will then fail to actuate the valve. In Figs. 1 and 3 the invention, is shown applied to a machine having bottle-raising pedestals comprising: sleeves 135 telescoping over air pressure tubes 139 communicating with a manifold. On each sleeve 135 is mounted a roller 158 which is depressed by a cam 161 and allowed to rise by a cam 162. Normally, the extent to which the pedestals rise is limited by contact of a bottle mouth with the inside of a centring bell 184, as shown at D and E. When a bottle is missing from a pedestal the latter rises higher, as shown at E, and the roller 158, passing beneath and, raising one end of a lever 230 pivoted at 231, depresses the other end of the lever, thus acting, via sliding valve 236, to cut off the pressure supply pipe 246 from a pipe 247 which communicates with a cylinder, 196 housing the counter-pressure trip 190. This trip is normally held outwards, in operative position, by air pressure on the piston 195, but when the pressure from pipe 246 is cut off and the air behind the piston escapes via port 248, spring 249 retracts the trip to inoperative position so that a filling valve arm 185 is not tilted thereby. The arm 185, filling trip 191 and neutral trip 192 are so designed that if the arm 185 is not tilted by the trip 190 it will not be tilted by the trips 191 and 192. By reason of a spring-pressed bevel catch connection 203 the cylinder 196 may swivel on its supporting pin 197 if the trip 190 is engaged by a jammed valve arm. In a modified machine for filling carbonated liquid into bottles containing syrup each pedestal 67a, Fig. 6, is urged upwards by a spring (not shown) positioned between telescopic tubes 317a, 318a. To the lower tube 318a is secured a slide rod 302a carrying a slide block 305a adapted to move vertically in a slideway 306a on the depending skirt of the filling table 142a. The blocks 305a carry rollers 308a, which normally hold a valve control lever 371, pivoted on the work table, in the position shown. In this position the counter-pressure trip 352 is held in operative position by compressed air coming from pipe 387 via valve 379 and pipe 389. When a bottle is missing the roller 308a rises abnormally high, the valve 379 is closed, bleeding takes place through valve 384, and spring 390a retracts the trip to inoperative position. The valve arm 409 is thus not tilted and is not tilted by the succeeding filling trip and snifting trip. Specification 522,297 is referred to.

Abstract: 378,167. Pulverulent-fuel burners ; pneumatic conveyers for pulverized material. CAMY, A. LABAT-, 48, Avenue des Gobelins, Paris. July 9, 1931, No. 19800. Convention date, July 10, 1930. [Class 75 (i).] Pulverized material such as coal is fed by gravity or a worm conveyer to a box 2 fitted with one or more tubes 1 having cutaway portions 4 surrounding adjustable blower nozzles 6 from which a gaseous fluid such as air is discharged to convev the pulverized material to its destination. In the pulverized fuel burner shown, the nozzles 6 are carried by arms 9 extending from an adjustable plate 11 in a chamber 15 to which air is supplied past a regulable damper 16. The fuel is fed from a hopper 3 to the box 2 through a double duct 28, 29, the outer wall being provided with openings 30 which admit air to prevent the fuel from packing. The cutaway portions 4 of the tubes 1 are spaced so that the fuel is drawn from different vertical zones by the air issuing from the conical ends 7 of the nozzles 6, which are also provided with perforations 21. The tubes 1 may be provided with helical fins 17 to whirl the fuel and air mixture as it is discharged into the combustion chamber. Secondary air for combustion is discharged from a casing 26 around the tubes 1. The screwed spindle 14 by which the plate 11 is adjusted may be linked to a pointer indicating the position of the nozzles 6 on a dial at the side of the chamber 15. In modifications all the nozzles 6 are independently adjustable, or one nozzle may be separately adjustable so that the mixture discharged from the corresponding tube 1 will act as a pilot jet during slow running. The burner, the feed hopper and a fan for supplying air for combustion and conveyance of the fuel may be mounted on a wheeled under-carriage which is movable relatively to one or more combustion chambers.

Abstract: 335,611. India Rubber, Gutta Percha, &. Telegraph Works Co., Ltd., and Avery, W. L. June 28, 1929. Addition to 309,470. Fluid-pressure.-The apparatus of the parent Specification comprising two brakes or two sets of brakes connected to two fluid containing chambers having pistons or the like controlled by a single operating rod capable of two movements one of which causes equal application of the brakes while the other causes differential application, is modified in that one of the movements of the rod is transverse to its longitudinal axis and the other movement is a rotation about that axis. The cylinders 10, 11 are disposed side by side and each has a piston 12 having a projection 21 loosely fitting into a tubular-member 22 of circular bore and square external section, a vertical pin 23 securing the parts for endwise movement but allowing the member 22 to adjust itself laterally. Toothed racks 24 are formed on each member 22 and engage a toothed wheel 28, the members being guided by vertical rollers 26, 27 and horizontal plates 19, 20. Flared holes 29, 30 in the toothed wheel are engaged by the forked end 31 of the operating rod 32 extending upwardly through longitudinal slots in the plate 19 into a casing 33 of oval section mounted in bearings 38. The rod is rotatable in the casing 33, and at its upper end is provided with a handle; rotation of the rod moves the pistons oppositely to give differential braking while swinging of the rod and casing 33 about the pivots 38 moves the pistons together for equal braking. Tubes 40, 41 connect each of the cylinders with the brakes and with a liquid supply respectively, the tube 41 being normally closed by spring-pressed cone valve 42 the stem 43 of which extends through a central aperture 44 in the piston 12 into a bore 45 in the projection 21 and has an enlargement 46 so that when the piston is near its extreme rearward position the valve 42 is lifted to replenish the cylinder as described in Specification 340,222, [Group XXXIV]. The rod 32 may be universally mounted by means of a flexible disc fixed to the toothed wheel. The pistons may face in opposite directions so that rotation of the rod gives equal brake application and transverse movement differential application. The cylinders may be arranged end to end. The operation rod may be cranked and in the case of an aeroplane connected to the usual control rod for operation thereby. The pistons may be replaced by flexible diaphragms, and suction may be used instead of fiuid pressure.

Filed: 1920-07-09
Abstract: 147,853. Ges. f³r Drahtlose Telegraphie. July 22, 1918, [Convention date]. Wireless telegraphy and signalling.-In highfrequency amplification arrangements employing thermionic valves in cascade, and particularly applicable when working with frame antennµ, one valve 1 is connected to the succeeding valve 2 through a chain conductor having inductances 3, 4 in series and condensers 5, 6, 7 in parallel when it is desired to amplify frequencies below a predetermined limit, or with the inductances in parallel and the condensers in series to amplify frequencies above a predetermined limit. By using two such chain conductors, in series, adjusted to different frequency limits, or by the use of a chain conductor which is a combination of the two arrangements, amplification of frequencies between those limits is obtained. Instead of condensers, inductance coils which have capacity, for example a number of superposed disk coils, may be used. The Specification as open to inspection under Sect. 91 (3) (a) suggests the possibility of using the internal capacities of the tubes as the capacities of the chain conductors. This subjectmatter does not appear in the Specification as accepted.
