Filed: 1949-02-02
Abstract: 654,410. Forcing liquids by air pressure. KNOWLES, A. V. Feb. 2, 1949, No. 2948/48. [Class 102(ii)] Means for dispensing liquid from a closed vessel a comprises a delivery pipe g depending into the liquid and a resilient diaphragm d having its edge engaged externally around the flange of a closure b which has a concave recess c forming, with the diaphragm, a substantially spherical chamber, the diaphragm having an air vent d<SP>1</SP> which is closed manually when the diaphragm is depressed to increase the air pressure in the vessel. Leakage is prevented even when the internal pressure increases due to slight increases of temperature. In one embodiment, Fig. 1, the air supply pipe e opens into a closed resilient sac i which is indirectly distended so that a temperature induced pressure increase in the botle will cause the sac to collapse. In another embodiment, Fig. 4, the inlet to the delivery pipe g is normally closed by a sleeve j connected by a wire l with a disc m separated by a narrow gap from a fixed disc n. Air passing through the gap bebetween the discs becomes rarefied causing the disc m to be raised together with the sleeve j. In another embodiment the air pipe e depends into the liquid level with the end of the delivery pipe and either the end of the air pipe or the ends of both pipes are normally closed by a spring reed which is opened by the air. In another embodiment the end of the delivery pipe is normally closed by a buoyancy capsule which sinks when air is forced into the vessel.

Patent GB-764272-A (GB)
Title: Improvements in or relating to treatment of glutamic acid containing hydrolysates
Filed: 1955-02-02
Abstract: The invention relates to the production of glutamic acid from precursors therefor (e.g. proteins) by hydrolysis with sulphuric acid, addition of a basic alkaline earth compound (e.g. calcium oxide or carbonate) to give a pH of 8-12 and filtering off the insoluble materials; it comprises the steps of acidifying to pH 4.5-7.5 with an agent which precipitates alkaline earth metals (e.g. carbon dioxide or sulphur dioxide), filtering, treating the precipitate with mineral acid and recovering glutamic acid from the resulting solution.  The precipitate may be returned to the process at a point prior to adjustment of the pH to 8-12 (before or after the acid hydrolysis). The solution after removal of the alkaline earth precipitate is concentrated to S.G. 1.1-1.2 when tyrosine and leucine crystallise out; further concentration to S.G. 1.2-1.75 and adjustment of pH to 2.5-3.5 brings about crystallization of glutamic acid.  The initial acidification is preferably to 4.5-6.0 when sulphur dioxide is used and 6.0-7.5 when carbon dioxide is used.  The starting material may be animal or vegetable proteins such as wheat or corn gluten, soyabean meal, cottonseed meal, casein, albumen or Steffen's filtrate. Examples are given of the process.  The specific gravity figures refer to that of the solution at 70 DEG  C.
