Title: A process for the production of natural phospholipids and related substances
Inventor: KLENK ERNST DR
IPC: C07F9/10
Filed: 1958-07-08
Abstract: A natural phospholipid is obtained from soya bean crude lecithin by extracting the crude lecithin with acetone, extracting the residual ester mixture with alcohol, allowing the alcoholic solution to stand for several days to clarify it from suspended colloidal particles, removing the alcoholic solution containing, as predominantly the basic component, a choline ester of diglyceride phosphoric acid, and recovering the said phospholipid from the alcohol solution, all steps being carried out in the presence of an inert gas at a temperature not exceeding 35 DEG C. whilst excluding the presence of oxygen and light.  The phospholipid obtained has a content of substantially 60% essential and other unsaturated fatty acids relative to the total fatty acid content.  The clarified alcoholic solution containing the choline ester of diglyceride phosphoric ester may be distilled under vacuum with exclusion of light and oxygen and in the presence of an inert gas e.g. nitrogen or CO2 and the product may be further treated to complete the separation of cephalin by passing an alcoholic solution thereof of 2-3% concentration at a temperature not exceeding 35 DEG C. with the exclusion of light and oxygen and in the presence of an inert gas such as nitrogen through an absorption column containing an alcoholic slurry of a carbonate and/or oxide of one or more elements of the second, third or fourth group of the Periodic Table, preferably Al and/or Mg and/or Si and eluting the slurry with alcohol.  On distillation of the alcoholic eluate under vacuum in the presence of an inert gas while excluding oxygen and light a chemically pure choline ester of diglyceride phosphoric acid is obtained which has a high content of essential fatty acids and is suitable for intravenous administration.  The chemically pure choline ester may be treated with snake venom to form monoglyceride phosphoric acid choline esters, the treatment with snake venom being carried out in a solvent medium, e.g. peroxide-free ether, in which the monoglyceride phosphoric acid choline ester is insoluble and the fatty acids which are split off in the alpha position are soluble. The invention also includes (a) a phospholipid containing a choline ester of diglyceride phosphoric acid as the basic component and containing substantially 60% essential unsaturated fatty acids, (b) a substantially chemically pure cephalin-free choline ester of diglyceride phosphoric acid containing substantially 66-70% essential unsaturated fatty acids, and (c) a choline ester of monoglyceride phosphoric acid having substantially 28% essential unsaturated fatty acid content, the percentage-essential unsaturated fatty acid content being based in each case on the total fatty acid content and an example is given in which such products are obtained from crude soya bean phosphaltides.

Abstract: 1,151,593. Jet looms. MACHINEFABRIEK L. TE STRAKE N.V. 17 May, 1966 [18 May, 1965], No. 21837/66. Heading D1E. A picking nozzle 6 and section storage tube 2 arranged to pick hairpins has a pusher 12 to push the first leg of the hairpin into the storage tube, a presentation 16 to push the free end into the nozzle for picking and a puller 17 to pull the second leg of the hairpin into the path of the presenter 16 for picking. In use, with the weft extending from a clamp 13 into an auxiliary storage tube and from thence to the supply the pusher 12 is operated (Figure 2, not shown) to push the weft into the storage tube 2. The weft is then drawn into the tube (Fig. 3) and the end of the loop extending into the clamp 13 then passes through a notch 14 (Fig. 1) so that'it is in the path of the presenter 16. The presenter 16 is then operated to present the loop to the nozzle so that, when the clamp 13 is opened, the first leg of the hairpin may be picked. After beatup the weft extends from the selvedge through a slit 7 in the nozzle to the auxiliary tube (Fig. 4, not shown). The pusher 12 is then again operated but, as the weft is not held in the clamp 13, the loop is drawn into the tube 2 without entering the notch 14 and is thus not in the path of the presenter 16. A member (not shown) then moves the weft outside the nozzle into the clamp 13. The puller 17 is then turned about its axis so that its hook 18 engages the thread (Fig. 6) and it is then pulled out of the tube (Fig. 7, not shown) so that the weft engages in a further notch 20 (Fig. 1) and, between this notch and the puller 17, is in the path of the presenter 16. The presenter may then push the weft into the nozzle for picking as the second leg of the hairpin simultaneously with the cutting of the thread outside the nozzle so that the thread then extends from the clamp 13 to the supply (Fig. 2, not shown) preparatory for another picking cycle.
