Patent GB-695504-A (GB)
Title: Method of isolating and purifying cholic and desoxycholic acids
IPC: C07J9/00
Filed: 1951-05-30
Abstract: Desoxycholic acid is isolated from a mixture of bile acids, by adding to the mixture a base in aqueous solution capable of causing preferential solution of the cholic acid.  Any weak base have a dissociation constant 1 x 10-5 to 1 x 10-8 affords a good separation, e.g. ammonia, morpholine and triethanolamine.  The base is added in an amount just sufficient to cause solution of the bile acids at an elevated temperature and on cooling the desoxycholic acid separates. When utilizing a volatile amine such as ammonia the base may be conveniently removed by evaporation depositing the desoxycholic acid. Any residual cholic acid in the deposited desoxycholic acid may be removed by treating with an aqueous isopropyl alcohol mixture made weakly basic by addition of 1 per cent of a weakly basic inorganic salt equal in chemical equivalent to sodium bicarbonate.

Title: Improvements in or relating to the de-aeration of liquids
Inventor: KULK JAN VAN DER
IPC: B01D19/02
Filed: 1955-05-06
Abstract: <PICT:0811572/III/1> Apparatus for de-aerating liquids having a tendency to foam when a vacuum is applied, e.g. oils such as salad oils, and in particular, oil blends containing emulsifying agents such as lecithin or mono- and di-glycerides used in the manufacture of margarine, comprises a vessel 10 with liquid inlet means 8 and vacuum outlet means 36 in the upper part of the vessel, liquid outlet means 34 in its lower part, means 31 for maintaining the liquid in the vessel at a predetermined level, and a member 26 which destroys the foam on the surface of the liquid by sweeping substantially the whole of the cross section of the vessel above said level in a plane parallel and in close proximity thereto. After de-aeration the liquid may be saturated with an inert gas by introducing it into a second vessel containing the inert gas at or above atmospheric pressure, after which the liquid, e.g. an oil blend, can be combined with aqueous ingredients in an arrangement for continuously producing margarine.  In such an arrangement, oil to be de-aerated is mixed in vessel 1 with oil-soluble ingredients normally included in margarine and conveyed by pump 5 to the spray manifold 8 from which oil is directed on to the walls of the vessel 10.  A vacuum is applied to the vessel 10 by a pump 37.  A motor 17 rotates blade 26.  Float 31 operates valve 7 to maintain the level of collected oil just below the level of the rotating blade 26.  De-aerated oil passes out of vessel 10 into vessel 44 through spray manifold 42 which functions similarly to manifold 8. Nitrogen at 4 atmos. pressure is supplied to the vessel 44 through conduit 49 from reservoir 52.  Float 48 operates in the same manner as float 31.  Oil saturated with nitrogen is drawn from vessel 44 into cylinders 58 of a proportioning pump, cylinder 57 of which draws aqueous ingredients from mixing vessel 55, the ingredients having been mixed in an atmosphere of nitrogen provided through distributer 54 from reservoir 52.

Title: Flow control device for example for the intravenous administration of liquids
IPC: A61M5/165
Filed: 1977-03-30
Abstract: The device possesses a supply chamber (10) having at least one inlet channel (8) and a filter chamber (11) communicating with the supply chamber (10) via a passage (14). An outlet chamber (17) is connected to the filter chamber (11). A first membrane (6) under tension is located in the supply chamber (10) and covers the passage (14) between the supply chamber (10) and the filter chamber (11) until the liquid pressure prevailing in the inlet channel (8) has reached a specified magnitude. The inlet channel (8) and the passage (14) open into the supply chamber (10) on the same side of the first membrane (6). The outlet chamber (17) houses a second membrane (7) which subdivides this chamber into two separate parts which are connected via a bypass channel (31). There are control devices (29) for adjusting the flow cross-section of the bypass channel (31). An outlet channel (30) is connected to that part of the outlet chamber (17) which lies downstream from the diversion channel (31). The second membrane (7) can be moved toward the outlet channel (30) and away from the latter in order to control the amount of liquid flowing through it as a function of the pressure differential prevailing between the two separate parts of the outlet chamber (30). The device permits precise control of liquids for intravenous administration. <IMAGE>
