Abstract: 1,213,158. Gas scrubbing process. RUHRCHEMIE A.G. 28 Dec., 1967 [26 Jan., 1967], No. 58863/67. Heading B1R. Gases from the sintering or wet-processing of phosphate rock enter a U-shaped gas scrubber at 11 and pass downwardly through limb 1 containing axially disposed spray nozzles 2 and then pass upwardly through limb 3 and are given a rotary motion 'by vanes (not shown) on the surface of an axially disposed body 4 above which a liquid spray 5 is arranged. Scrubbed gases are withdrawn at 12 after passing through a droplet eliminator 13 and sludge-containing liquid is withdrawn at 10. Liquid may also be introduced into limb 1 at 16 to prevent accumilation of dust adjacent the inlet. Calcium hydroxide may be added to the scrubbing liquid for the removal of fluorine compounds from the gases and the amount of added hydroxide is such that the pH of the liquid separated in eliminator 13 is about 8.

Title: Seal for prossurized containers
IPC: F16J15/08
Filed: 1968-09-13
Abstract: O-ring has convex contact surfaces and is placed between two opposite annular grooves with concave contact faces and they are set in an element by clamping. The ratio of the radius of curvature of the convex faces of the O-ring to that of the concave faces of the grooves is in the range of 0.5 to 0.85.

Title: Process for preparing stable nitrate/slurry explosives
Inventor: OWEN JAMES HERMAN II
IPC: C06B47/14
Filed: 1986-03-10
Abstract: Explosives that are sensitized blends of inorganic nitrate. e.g., AN, particles, such as AN or ANFO prills, and an aqueous slurry comprising a thickened aqueous solution of an inorganic oxidizing salt, preferably AN, are rendered storage-stable by keeping the slurry's water content low enough, and its viscosity high enough, that the slurry is water-retentive. Water immobilization in the slurry, a requirement for storage stability, is achieved despite the slurry's flowable consistency at the time of blending. A blend containing about 25% slurry or less, is essentially in the form of a granular mass of free-flowing, high-density, slurry-bearing prills, and the slurry is sensitizable by the prills alone. As the slurry content exceeds about 25%, the blend takes on the characteristics of a thick slurry, requiring a supplemental sensitizer in the slurry perse. Slurries containing a nitrogen-base salt of an inorganic oxidizing acid, preferably monomethylamine nitrate, are preferred because this additive affords a saturated solution with lower water content, and also can act as a sensitizer.
