TL;DR: In this article, a condensed cadmium spark was used as the source of radiant energy; alcoholic solutions of the substances were employed, except for stearic acid, which was dissolved in ether.
Abstract: This investigation is to discuss some of the conditions which influence the absorption spectra of various “saturated” and “unsaturated” organic compounds. A condensed cadmium spark was used as the source of radiant energy; alcoholic solutions of the substances were employed, except for stearic acid, which was dissolved in ether. The vapours were examined in a quartz tube 200 mm. long, placed in a bath which could be heated to various temperatures.

TL;DR: In this article, a process for removing sulphur compounds from the vapours of hydrocarbon liquids, e.g. gas oils, is described. But it does not specify the rate of circulation between the absorber and regenerator.
Abstract: In a process for removing sulphur compounds from the vapours of hydrocarbon liquids, e.g. gas oils, the vapour is passed through one or more fluidized beds of particles of an oxide such as iron, manganese or zinc oxide and the sulphur content in the bed or beds is maintained below 10% and preferably below 2% by the continuous withdrawal for regeneration of oxide from the bed or beds and the return thereto of regenerated oxide. The oxide is regenerated by heating under oxidizing conditions and the rate of circulation between the absorber and regenerator is such that the whole mass of oxide in the absorber is changed at least once every 4 hours and preferably at least once every hour. Specification 719,056 is referred to.

TL;DR: In this paper, the critical energy E* of direct initiation of a detonation wave (DW) is accepted as the main criterion parameter of detonation hazards of gaseous mixtures.
Abstract: The critical energy E* of direct initiation of detonation wave (DW) is accepted as the main criterion parameter of detonation hazards of gaseous mixtures. The blast explosion approximation is proposed to use at experimental definition of E*. This technique is identically suitable both to various mixtures and various initiators with of large distinctions in the spatial-temporary energy-release characteristics (flame igniters, electrical or laser spark, exploding wire, explosive, high-speed bullet...). The priority at theoretical definition of critical detonation energy is given up to «multi-points» initiation model (MPI) based on DW transverse waves collisions as the microinitiators of a detonation («hot» points). The hazard parameters were calculated with the help of Computer Code «SAFETY». The basic parameters of detonation and explosive hazards of some typical fuels (interesting from scientific and practical points of view) are presented in a wide range of its concentration in mixtures with oxygen and air, and at dilution of inert gases. The dependence of critical initiation energy E* on percentage of fuel in a mixture allows to find out comparative detonation hazards of various combustible systems at plane, cylindrical and spherical initiation. Calculated results are in a good agreement with experimental data.
