Filed: 1921-09-08
Abstract: 186,812. Moorhouse, E. A. Sept. 8, 1921. Grates; fire-bars. -In a rotatable fire - grate wherein the fire-bars are carried in front and rear frames mounted on spindles carried by the dead-plate G<1>, and bridge-plate G<2>, so that the grate as a whole may be rotated by hand, the grate is in two halves, as shown in Fig. 2, and the fire-bars are rhombus-shaped in cross-section, and so mounted that any fire-bar can be removed independently. As shown at F, Fig. 4, the top and bottom halves of each bar correspond, so that either half may constitute the grate surface, the ends being flattened to prevent burning. Each bar may be integral or be made of a number of sections threaded on a central rod. The bars are provided with a tie-head, show at E, so that when the bars are assembled in the front and rear frames J, K, the heads fit together as indicated by the full lines at J, and may be secured by wedges &c. As each bar is passed through separate holes in the carrying-frames, it may be removed independently.

Title: Improvements relating to the breaking of emulsions
IPC: C10G33/04
Filed: 1944-12-04
Abstract: In the sulphuric acid treatment of hydrocarbons, a polymer, as defined below, is intimately mixed with the acid prior to its introduction to the reaction zone to assist breaking of p acid-hydrocarbon emulsions.  The polymer is the non-gaseous product obtained by diluting spent acid, from a sulphuric acid treatment of a hydrocarbon, with a substantial proportion of water while agitating and heating to boiling, and thereafter allowing to settle, preferably for a long period not substantially above 4 hours, and separating the supernatant layer.  In the alkylation of isoparaffins with olefins, spent acid may be diluted to about 50 per cent, as by addition to steam condensate while agitating and boiling, allowed to settle for 4 hours, and the polymer layer separated.  It may be dissolved in oil if too viscous for pumping. It is added to fresh acid in amounts which are generally not above 5 per cent by weight.  Sulphuric acid refining of hydrocarbons is also referred to.
