IPC: E03B5/04
Filed: 1960-07-05
Abstract: 885,833. Water supplies. TAIT MANUFACTURING CO. July 5, 1960, No. 23488/60. Class 68(1). In a water supply system in which water is pumped into a tank 10 and retained therein under air pressure until drawn off from the tank, the tank is provided with means for regulating the pressure of the air above the water in the tank. The means comprise a housing 30 secured in the side of the tank, a bore 32 extending through the housing being closed off by a flexible diaphragm 57 through which passes and in which is pivotally secured the float arm 56 of a ball float 55. The arm controls two opposed spring-biased valves 37, 46 in the housing. The valve 47 allows venting of the tank to atmosphere when the air pressure in the tank becomes excessive and unduly restricts the rise of water in the tank. The valve 37 allows entry of air into a pipe 41 when the level of the water in the tank rises unnecessarily far due to insufficient air being present in the tank, the air passing the valve 37, pipe 41, and non- return valve 45 into the supply pipe 13 from the pump 20 to the tank 10 as the supply pipe 13 on the ending of a pumping operation is always drained back into the well through a bleed passage in a non-return valve at the pump outlet. On the pump being subsequently started up by a pressure-responsive switch 25 in the tank the air in the pipe 13 passes through a non-return valve 22 and enters the tank.

Title: Improvements in valves for venting air from water mains and the like
IPC: F16K24/04
Filed: 1927-09-08
Abstract: 297,564. Blakeborough, R. A., Brotherton, C., and Broadhead, J. B. Sept. 8, 1927. Air traps.-In a valve for automatically venting air from water mains and the like, comprising a buoyant member g slidable vertically in a chamber a disposed above and open to the main d, the member g carrying at its upper end a valve j adapted to co-operate with a vent opening formed in the top of the chamber, an adjustablyweighted lever h tends to move the member in a valve-closing direction. As shown, the valve j has an axial passage j<1> controlled by a needle valve k carried by a buoyant ball m slidable vertically in a cage n arranged in the upper end of the hollow member g, which latter is provided with ports g<2>. A stem g<1> projecting from the lower end of the member g through a stuffing-box f is closed except for an outlet passage g<3> controlled by a valve o connected to the lever h by a link o<1> in such a way that the valve is opened when the member g has descended a certain distance and is closed as the member rises. A valve e is provided for isolating the chamber a from the main when required, and the chamber is provided with a drain-cock s and an air-cock r. Small accumulations of air under pressure are dealt with by the valve k. Large accumulations of air cause the descent of the member g, which contains water entering through the ports g<2>, thereby opening the valves j, o. Water escapes from the member g through the passage g<3>, the member rises, closing the valve o, and water again enters the member g, causing the valve k to close. The lever h may be arranged to act on either the lower or upper end of the member g. In a modification for dealing solely with air in volume, the valves k, o are omitted, the member g being completely closed, while in a further modification for dealing solely with air under pressure, the valve j is in the form of a needle valve. For dealing with air both in volume and under pressure, two separate valves according to the two last-mentioned modifications may be arranged in the chamber a.
Patent GB-804970-A (GB)
Title: Improvements in or relating to the purification of lysine
Filed: 1957-07-25
Abstract: An impure aqueous solution of lysine or a water-soluble salt thereof containing amine impurities including one or both of di- and tri-(5-amino-5-carboxypentyl) amine is purified by passage through a strongly oxidic cationexchange resin, removing at least part of said amine impurities from the resin and subsequently removing lysine of increased purity from the resin.  The purification may be effected in two preferred ways.  Using low lysine loading of the resin, the solution is passed through a bed of resin in the acid or ammonium form, preferably the former, to absorb lysine and impurities, and the latter selectively eluted with dilute aqueous ammonia, preferably of concentration 0.1-0.7 per cent NH3, through an unloaded portion of the bed in the ammonium form, such unloaded portion preferably being at least one-third the length, more preferably one to two times the length of the loaded portion; the lysine remaining on the resin is subsequently eluted.  Using high lysine loading of the resin, the solution is passed through a bed of the resin in the ammonium form until the bed is substantially completely loaded with lysine and preferably overloaded, preferably until 0.1-15 per cent, more preferably 2-10 per cent, of the lysine fed to the column has passed into the effluent.  After a water wash, the lysine is eluted from the resin.  The elution of lysine is preferably effected with aqueous ammonia of strength 5-29 per cent NH3.  Preferably room temperature is used.  Suitable resins are those having strongly acidic functional groups such as sulphonic, phosphonic or phosphorous acid groups. Preferred resins are the sulphonic acid type such as sulphonated coals, sulphonated phenol-aldehyde resins and nuclear sulphonated aromatic hydrocarbon resins.  Particularly preferred are the nuclear sulphonated aromatic hydrocarbon cross-linked resins such as the sulphonated copolymers of a monovinylbenzene and a polyvinylbenzene, particularly sulphonated styrene-divinylbenzene copolymers having the equivalent of from 4-16 per cent divinylbenzene.  The resin is used in particulate form, generally of 20-100 mesh, and preferably of 20-50 mesh (U.S. Standard screen scale).  Repeated purification and re-cycling may be employed.  Examples describe various procedures of the process of the invention.
