Abstract: 714,095. Endless belt conveyers. HERTEL, R., and HERTEL, D. Jan. 18, 1952 [Jan. 19, 1951], No. 1552/52. Class 78(1) Apparatus for maintaining a conveyer belt in a predetermined path comprises one or more rollers in surface engagement with the underside of the belt which is or are displaceable with the belt on lateral deviation of this from a predetermined path so as to alter the angular disposition of a supporting roller for the belt through a lever connection, whereby the band is restored to its predetermined path. Figs. 1, 2 show the application to a conveyer belt supported by troughing rollers mounted on a support 4 pivotally mounted on a vertical pivot 20. Should the belt deviate sideways it displaces rollers 1 laterally on their shaft 3, whereby a collar engaged by a fofk 6 on an arm 5 secured to the support 4, is also displaced along the shaft 3 so as to turn the support 4 about its pivot 20. The troughing rollers are thereby skewed relatively to the belt and exert a correcting force tending to restore the belt to its predetermined path. In another embodiment Figs. 5, 6, the rollers 11 are mounted in forks 12 pivotally supported in bearings 14 carried on a cross piece 22 having arms 23 mounted on a shaft 24, springs (not shown) acting on these arms whereby the rollers 11 are pressed resiliently against the underside of the conveyer belt. Should the belt deviate sideways, the rollers 11 are displaced laterally and the forks 12 pivot in their bearings 14 whereby pins 13, fixed to the forks and engaging at their lower ends in slots in an arm 15 secured to the troughing roller support 16, effect angular movement of the support about its pivot 21.

Title: Improvements in or relating to the synthesis of ammonia
IPC: C01B3/02
Filed: 1924-01-31
Abstract: 233,040. Casale, L. Jan. 31, 1024. Nitrogen. - In the synthetic production of ammonia, electrolytically-obtained oxygen is used alone or mixed with air for the gasification of fuel and in admixture with air for the combustion of the gaseous products to yield a gas which, after elimination of carbon dioxide, consists of nitrogen. The oxygen from an electrolyzer 1 passes to a gasometer 4 from which a fan 6 withdraws it, if desired in admixture with air admitted by the pipes 5, to a gas generator 7 containing a fuel such as lignites or peat. The gaseous products are passed through a purifier 8 to a boiler 9 of a power unit, where they are burnt by means of air admitted by the pipe 5<a> and oxygen conducted through the tube 5b. The power developed is used to generate electricity for the electrolysis &c. while the condensed steam from the boiler is used in the electrolyzer. After being cooled in the condenser 10 the burnt gases consisting of nitrogen and carbon dioxide are conducted by the fan 11 to the gasometer 12. Thence they are withdrawn at will, compressed in a compressor 13, and the carbon dioxide content eliminated in the refrigerator 14 and water scrubber 17, leaving pure nitrogen.
