Abstract: Vegetable oils are refined by treatment with an aliphatic monobasic or dibasic acid anhydride wherein the alkyl groups contain from 2 to 6 carbon atoms.  In particular the anhydride is used in the removal of gums from the oils by mixing them with water and separating the aqueous phase containing the gums from the oil.  The anhydride may be added to the water, to the oil or to the oil-water mixture.  The oils treated are preferably lecithin-bearing vegetable oils, such as soybean, cotton-seed, perilla, linseed, peanut, corn and tung oils. The anhydrides specified comprise acetic, propionic, butyric, maleic and succinic acid anhydrides alone or in admixture.  Lower alkyl substituted derivatives may also be used such as monomethyl succinic acid anhydride and dimethyl succinic acid anhydride. The proportion of anhydride is preferably 0.05 to 1 per cent of the weight of the oil.  The treatment may be effected at 40-100 DEG C., preferably 60-85 DEG C.  The mixture of oil, water and anhydride is agitated for a suitable period and then centrifuged to separate the aqueous phase containing the gums and leave a break-free oil.  The oil may then be bleached with clay or active carbon, and then deodorized with steam at elevated temperature and under vacuum to remove fatty acids and sterols.

Abstract: 1,063,748. Lubricating; valves. EATON YALE & TOWNE Inc. July 29, 1965 [May 7, 1965], No. 32485/65. Headings F2A and F2V. In a valve means, a valve block (213), Fig. 1 (not shown), has a piston slidable in a box (221) for alternatively supplying lubricant from inlet means (247) to two outlet openings (216, 217), has a passage (260) connecting two outlet ports (253, 254) to the outlet openings (216, 217), and has closure means (270) in the passage (260). The closure means (270) may comprise a screw (273), Fig. 5 (not shown), having a truncated end (271) which is engageable with a conicalshaped chamber (272). When in the open position a washer (277) is positioned between the head (274) of the screw (273) and the block (213), sealing being effected by means of an insert (276) of plastics material. When in the closed position the washer (277) is removed, the head of the screw abuts the block (213) and the truncated end (271) engages the conical-shaped chamber (272). Alternative screws and sealing thereof include a washer (284), Fig. 8 (not shown), located between the head thereof and the block (213); a disc (291), Fig. 9 (not shown), located at the end of the screw; a reversible resilient washer (293), Figs. 11 and 12 (not shown); and a reversible screw (302), Fig. 13 (not shown). Threaded plugs such as (222), Fig. 3 (not shown), and welded balls (286) close the ends of cylinders and passages respectively. In use, lubricant supplied at (215), Fig. 1 (not shown), fills a passage (200) and issues from an inlet port (247) in a central chamber (232) of block (213a) and enters a branch (251) of a transfer passage (243). Since the piston in the block (213a) is then to the left, a transfer passage (244) is cut off from the central chamber (232). This applies pressure to the left-hand end of the cylinder in the block (213b) causing that piston to move to the right and expel lubricant through passages (244 and 246) across an intermediate chamber around the piston-neck (230) and out through the outlet port (254) and a passage (239) through the outlet opening (217) only, due to the closure means (270) being in the closed position. However, if the lubricant is required to issue from the outlet opening (216) and join that discharged therefrom when the piston in the block (213b) moves to the left, then the outlet opening (217) is plugged and the closure means (270) is opened.
