Title: Improvements in machines for manufacturing metallic network
IPC: B23K11/00
Filed: 1949-12-30
Abstract: 677,357. Making wire-mesh. MEACHER, W. Dec. 27, 1950 [Dec. 30, 1949], No.33402/49. Classes 83 (ii) and 83 (iv). [Also in Group XXXII] Welding by pressure.-A multiple spot welder for the manufacture of welded wire mesh of the type described in Specification 461,640 comprising a table reciprocated by a cam and a cam follower, is characterized in that means are provided for adjusting the relative positions of the cam follower and the table. Beneath the table 1 are disposed two pivoted arms 4, one at each side and each carry a cam follower 5 which engages a cam 6 on a shaft 7. The upper end of each arm 4, remote from its pivot 8, is coupled to the table by a threaded rod 9 passing through an eye 10 pivotally secured to the table. Nuts 12 on the rod allow the effective length of the rod to be adjusted to give the required stroke of the table for a particular size of mesh. The cam followers are pivoted at 14 on the arms 4 and are provided with coupled rollers 15 and 16. For maximum stroke the rods are arranged so that when the table 1 abuts limit stops 33 the rollers 15 just contact the cams 6 at their lowest contour. The stroke may be reduced by shortening the rods 9. The second roller 16 enables the stroke to be increased with a given cam eccentricity by taking over from the roller 15 when the latter is lifted above the cam centre. A stop 34 on the arm 4 limits the movement of the follower. The table is returned against the stops 33 by springs (not shown) and a dashpot 20 prevents shock to the machine. The dashpot (see Group XXXII) is coupled to one arm of a bell-crank lever, the vertical arm 24 of which is forked to receive a rod 30, one end being secured to the table and the other carries an adjustable stop 31 adapted to engage the fork. The stop 31 is adjusted to operate the dashpot before the table abuts the stops 33. To obtain uniformly strong welds across the width of the machine the top and lower electrodes are mounted on two bus-bars opposite to one another, the bus-bars being connected to the secondary of the transformers. Thus, wherever the electrodes are positioned on the bus-bars the welding circuit has the same length of copper conductor and tends to have the same impedance. Specification 451,037 also is referred to.

Patent GB-777979-A (GB)
Title: Improvements in or relating to travelling wave tubes
IPC: H01J23/027
Filed: 1954-11-19
Abstract: 777,979. Travelling-wave tubes. TELEFUNKEN GES. Nov. 19, 1954 [May 22, 1954], No. 33533/54. Class 39(1). Power loss at the collector electrode of a travelling-wave tube is reduced by providing in the space between the delay electrode of the tube and the collector electrode a screen electrode which is connected to the delay electrode and prevents substantial penetration of electronic field lines from the collector electrode back into the interaction space of the delay electrode, thus enabling the collector electrode to be maintained at a considerably lower positive potential than that present on the delay electrode. The tube shown comprises an electron gun 5 for projecting an electron beam through a helix 3 to a collector electrode 6, the beam being concentrated by the magnetic field of a coil 7. High-frequency waves to be amplified are fed to an input electrode 1 by a waveguide 4 having an extension tuned by a plunger 8, and the amplified waves are fed from an output electrode 1<1> to a waveguide 41 having an extension tuned by a plunger 81. Alternatively the input and output waveguides may be replaced by hollow tubular line sections terminated by short-circuited quarter-wave line sections. The helix 3 is supported by three ceramic rods 2 provided with strips 10 of lossy material such as carbon which are shaped at their ends for matching purposes. The rods 2 extend between the coupling electrodes 1 and 1<1> which, together with the electron gun 5 are held in position by a support system including three ceramic rods 9. The end of the helix 3 is connected to a tubular extension 15 of a screen electrode 11 in the form of a metal disc which is fused to the envelope 12 and lies between the end of the helix 3 and the collecting electrode 6. The aperture in the tubular extension 15 is slightly larger than the electron beam crosssection, and the diameter of the bore in the collector electrode 6 is larger than or equal to the diameter of the said aperture. The main body of the screen electrode 11 may be made of ferromagnetic material and the tubular extension 15 of non-ferromagnetic material. The arrangement enables the potential of the collector electrode 6 to be as low as 200 volts, with the helix 3 at a potential of 1200 volts positive relative to the cathode. The power loss is sufficiently low to enable power tubes to be operated without compressed air blast or other forced cooling, the cooling fins shown on the collector electrode structure being sufficient. In the case of low power tubes even these cooling fins can be omitted.

Abstract: 976,607. Feeding records in punching machines. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 26, 1963 [Aug. 27, 1962 (2)], No. 33641/63. Heading B4B. [Also in Divisions B6 and G4] A record card 1, Fig. 1, is advanced step-bystep through a processing station in a punching machine by moving the card forward intermittently and, after each forward movement, moving the card backwards so as to abut against successive stop-members 14. The intermittent forward movement may be obtained by means of a recessed roller 4, and the backward movement by a pair of continuouslydriven rollers 8, 9. Rollers 8, 9 may be skewed to align one edge of the card against edge 13 of support plate 2. Column skipping may be achieved by the arrangement shown in Fig. 3, a roller 18 being brought into engagement with the recessed portion of roller 4 for normal stepby-step advancement of the card, and a roller 19 being brought into engagement with the continuous surface 17 of roller 4 to effect column skipping. In another embodiment, Fig. 5, two rollers are eccentrically mounted on shafts carried by a reciprocating frame 22. Arms 28, 29 are rigidly attached to the rollers and are biased together by a spring 30. As frame 22 moves forward, the card 1 is gripped between the rollers and is advanced thereby, and when frame 22 moves backwards, card 1 moves backwards until it is stopped by a member 14, and thereafter the rollers slip over the card and ensure that it is correctly aligned. Card feed may be interrupted by forcing arms 28, 29 apart by means of a cam.

Title: Process for recovering nitrose gases as ammonium nitrate
IPC: C01C1/18
Filed: 1954-11-22
Abstract: In the production of nitric acid by the absorption of oxides of nitrogen in water, the residual gas is passed, together with carbon dioxide, preferably 2.5-7.5 per cent and sufficient nitrogen peroxide-rich oxides of nitrogen to produce a molar ratio of NO2:NO of 1:1 or greater, into an expansion turbine whereby the gases are mixed and cooled to a temperature of 0-10 DEG C. the resultant gaseous mixture is treated with aqueous solution containing ammonium carbonate whereby the oxides of nitrogen are absorbed and the solution is cooled to and maintained at the temperature of 0-10 DEG C., and the resulting solution is admixed with aqueous nitric acid, e.g. of 50 per cent concentration, such that the pH of the mixture does not rise above 2, preferably not above 1, and the temperature above 25 DEG C. whereby a solution of ammonium nitrate is produced and oxides of nitrogen are evolved. The gases are preferably cooled to 0-5 DEG C. by the gas turbine. The oxides of nitrogen evolved may be recycled after oxidation to produce nitrogen peroxide-rich gas to the nitric acid production step or partly to said step and partly to the residual gas treatment step at the gas mixing stage.  In the former case nitrogen peroxide-rich gas may be supplied to the residual gas treatment step by bleeding off from the nitric acid production step.  Any ammonia blown out during the absorption in the ammonium carbonate solution may be recovered by subsequent absorption in aqueous nitric acid solution.  The ammonium carbonate solution may be produced by the interaction of ammonia and carbon dioxide under superatmospheric pressure in the absorption solution or an associated cycle.  The ammonium carbonate solution preferably contains at least 30 per cent ammonium nitrate.  The absorbent solution may be mixed with the nitric acid by injecting the absorbent solution through one or more jets in an injector type nozzle through which the acid flows. Specification 685,726 is referred to.
