Title: Process and apparatus for the production of ammonia
Inventor: SCHOLZ WALTER
IPC: C01C1/04
Filed: 1966-11-11
Abstract: A crude gas containing hydrogen and carbon monoxide is treated by conversion of the carbon monoxide, removal of carbon dioxide from the converted gas by scrubbing and removal of the last traces of impurities from the scrubbed gas and then subjected to ammonia synthesis; the crude gas being produced and purified at substantially the same pressure of 80-220 atmospheres. The ammonia synthesis is preferably also carried at this same pressure.  The last traces of impurities are preferably removed by scrubbing with liquid nitrogen at just above its solidification temperature.  Sulphur compounds, hydrocarbons and carbon dioxide can be removed by scrubbing with an organic solvent such as methanol.  The sulphur compounds and hydrocarbons may alternatively be removed in an extra scrubbing stage with, for example, xylene or methanol, prior to the conversion of the carbon monoxide. missing page 176

The apparatus also includes a pair of co-operating shear blades 150, 152, a centering device 156 for locating the wires in a predetermined spaced array at the work zone 151 prior to wire trimming by the blades, and an anvil 204 adapted to support terminals 200 having open ferrules (266), Figs. 7-9 (not shown), and a crimping die 222 movable relative to the anvil for crimping the ferrules about respective wire ends. The wire gripping member 50 is pivotable on a pin (72), Figs. 10, 11 (not shown), between a cable loading position and a cable securing position by means of a handle 56. The straightening mechanism 22 has a housing 136 mounted for both axial and rotational movement at the end of a shaft 138. A member 144 of polyurethane is mounted on the lower arm 134 to define a gap 146, Fig. 4, when the arms are in a closed position. A roller 112 is mounted on a pivotable support 114 for movement along the template. In operation, a rotatable cam assembly 165 initiates downward movement of a slide 160 and with it the centering device 156 and shear blade 150. After trimming the wires the blades 150, 152 are moved away from the work zone 151 by the provision of a cam track 180 on the ram 184 and a cam follower 182 attached to the housing 164. Thus, as the slide 160 moves downwardly the blades are moved transversely and crimping can be performed using the die and anvil assembly, the template 30 having been previously moved to a lower position by a wire clamp plate 206. The template is mounted on a block 230 and is vertically movable by way of a slide 234 secured within an aperture 232 in the block. The slide is attached via a lever arm 238 and link 244 to a lever 242 movable by a cam 252 and pivotally mounted to a bracket 240 to which lever 238 is also pivotally mounted. The position of the template can therefore be set corresponding to various operations of the apparatus.

Abstract: 1357467 Photo-electric testing F FORSTER 23 Nov 1972 [22 Dec 1971] 54249/72 Heading G1A In an arrangement for determining the quality of the weld of a seam welded tube, the heat energy dissipated in the weld seam during its manufacture is determined by successive scans over portions displaced along the length of the tube by means producing an electrical signal in response to the heat or infrared emanating from the tube whilst it is still hot or in response to the change in diffuse reflectivity caused by temperature discolouration in areas adjacent the seam after cooling. Infrared responsive photo-resistors 9, 10, Fig. 1 are rotated to effect the scan through an arcuate aperture 14 in a disc 11. Peak voltages and integrals of the pulse signals are obtained and may be recorded. The peak signals which are stored for each scan are erased by pulses from terminals 17 caused by magnets 19, 20 passing over coil 15. In an alternative embodiment an apertured disc with a reflective underside is rotated between the running tube and a pair of transducers fixed over the line of the tube. In the diffuse reflectivity embodiment Fig. 4, (not shown) the tube is passed through a rotating sleeve carrying a pair of lamps and a photo-cell. The arrangements may be used in conjunction with magnetic non- destructive tests, and the pulses from scanning may be used with the timing pulses to monitor the straightness of the seam. In a further modification a number of sensors attached to the periphery of a disc rotating about an axis parallel to the line of the tube effects the respective successive scans. The peak or integral signals may operate alarms.
