Slipping vehicles. - In high-speed mono-rail suspension railways, trains are reversed by a series of turntables each dealing with a part of the train. Each train-portion or vehicle is slipped from the train and brought to rest when over its appropriate table. The last rail of the fixed track 117 is deflected by the vehicle weight to remove lever 113 from the range of an arm 112 carried on the vehicle. When the train has left rail 117, lever 119 lowers lever 113 which is engaged by arm 112. Arm 112 is lowered to slip the vehicle or train-portion and apply its brakes, and lever 113 is moved further to actuate rod 126 on table 103 and rod 127 on table 104 to operate catch 128 and release lever 114 for engagement by the last vehicle but one. When the train has been split up, the tables are rotated, the brakes released, and the end vehicle starts in motion and re-couples the train. The levers 114 are re-set by the engagement of a vehicle arm such as 135 with a cam 115<1> on each lever. Lever 113 is reset by the engagement of the end 121 of rod 122 with a fixed ramp on the track at the end of the turning movement.

Abstract: 295,272. Compagnie Internationale pour la Fabrication des Essences et Petroles. Aug. 8, 1927, [Convention date]. Materials for purifying; purifying processes ; purifier waste, revivifying. - In the hot purification of distillation &c. gases employed in the continuous working of plant for the manufacture of light hydrocarbons in which metal or oxides, e.g. an oxide of nickel, are sulphided and regenerated, one of two series of purifiers being placed alternately out of circuit for the regeneration step, a further pair of small protective purifiers is arranged to follow the main apparatus each purifier being alternately placed in and out of circuit at much longer intervals and containing metals such as copper or oxides which form sulphides stable at the operative temperature, approximately 250‹ C. In the plant shown the gases freed from products boiling above 400‹ C. are led alternately through purifiers B<1>, B<2> and B<3>, B<4>, and thence through one or other of the protective purifiers E<1>, E<2>. Whilst the main purifiers may be em. ployed for one to six hour periods the protective purifiers may be in use for one to six weeks. Regeneration of the agents in the main purifiers is effected in three stages. A reducing gas, preferably at 300-400‹ C. is first admitted by a pipe H through cocks f<1>, f<2> - -, and the sulphuretted hydrogen and water vapour produced are discharged through pipes I<1>, I<2> - - into a collector I leading to a water vat K. The reducing gas may before entry pass through a heated vessel F', F<2> - - - containing finely divided metal, e.g. nickel, to cause the hydrogen present to pass into the nascent state. In the second stage hot air or oxygen is admitted by pipes G', G' - - - and sulphur dioxide and water vapour pass by pipes J<1>, J<2> - - - through a collector J into the vat K, sulphur being liberated by reaction with sulphuretted hydrogen. To remove basic sulphates formed in the second stage the reducing gas is again passed into the purifiers as a third stage, sulphur dioxide being liberated. A single pipe may replace the collectors I, J, one outlet only being provided for each purifier. The purifiers may comprise three vessels in series as described in Specification 267,138. Specification 274,846 also is referred to.
