Abstract: <PICT:0454891/IV/1> <PICT:0454891/IV/2> <PICT:0454891/IV/3> <PICT:0454891/IV/4> The concentration of aqueous aliphatic acids in counter-current with a solvent is effected so that the aqueous solution forms a series of films, part of each film being in contact with one of a vertical series of solid surfaces spaced apart and part being bounded on both sides by the solvent.  In the apparatus shown, dilute acid from a source 1 is concentrated to about 40 per cent strength and led to a tank 9 from which it flows into the bottom of a column 18 which receives solvent from a tank 12 through a pipe 17, the flow being controlled by a float valve 15.  The column contains a series of tray units 30 comprising trays 32 carried on rods 31, Fig. 3.  The trays make sliding contact with the walls of the column 18 and are shaped as shown in Figs. 5 and 9, the lower trays being smaller than the upper.  The water from which the acid has been extracted escapes through a separating chamber 16 and pipe 19, and the solvent extract passes from a chamber 11 at the bottom of the column by a pipe 20 through a tank 21 to a still 23 from which the vaporized solvent passes to the tank 12 and the concentrated acid is led to a tank 26.  The apparatus may be of glass, stainless steel or bronze.  Suitable solvents are methylene and ethylene chlorides, ether, phenol ethers, and mixtures of kerosene or benzol with ethyl ether, ethyl acetate, chloroform, or acetone oil.  Specifications 283,702 and 301,734, [both in Class 2 (iii)], are referred to.

Abstract: 971,194. Dispensing liquids. FISHER & LUDLOW Ltd. July 17, 1963 [July 19, 1962], No. 27684/62. Drawings to Specification. Heading A4T. [Also in Division G4] A beverage dispenser measures out a quantity of liquid at each transaction by the timed operation of a valve, the decreased pressure as the liquid falls in its reservoir being compensated for by increasing the time of operation of the valve. In association with a cup-dispenser as described in Specification 970,093, see Division B8, the valve timing is varied when the reservoir is one third and two thirds empty as determined by the exhaustion of the first and second of three stacks of cups. Two cam operated contact sets control the valve, one set operating for 2¢ seconds the other operating ¢ second later than the first set and staying operated for 3 seconds so that the contact sets are operated together for 2 seconds. With the first stack of cups present, the contact sets are connected in series with the valve operating solenoid to use the period of 2 seconds. When the first stack is exhausted, contacts shunt the 3 seconds set to use the 2¢ seconds period. When the second stack is exhausted the 2¢ seconds set is shunted and the shunt removed from the 3 seconds set.

Filed: 1964-07-06
Abstract: 1,068,319. Capacitors. STRATFORD RETREAT HOUSE. July 6, 1964, No. 27770/64. Heading H1M. A capacitor is manufactured by preparing a plurality of elements consisting of unfired ceramic wafers 10 having electrodes 12 on at least one face, stacking the elements and encapsulating the stack by surrounding it with ceramic powder or placing it between unelectroded ceramic wafers and pressing the powder or wafers. The encapsulated arrangement is then fired. Each capacitor element may be formed from a wafer of titanium dioxide covered by electrodes of platinum or palladium in paste form. These electrodes may extend around the edge of the wafer as shown in Fig. 6. A number of elements are assembled in a jig, with like electrodes adjacent, and surrounded by a titanium dioxide ceramic powder. Pressure is applied and the assembly is then fired in a furnace. Notches 42, 43 are cut into the sides of the unit and into the electrodes so that leads 40 and 41 may be connected by soldering (37 being an electrode solder layer). Alternatively the electrodes may cover only the central areas of the ceramic wafers, with small tabs extending to the edges to enable contacts to be made. After these elements have been stacked together several plain ceramic wafers are placed above and below the stack, and this arrangement is compressed, fired, notched to enable leads to reach the extending tabs, and otherwise treated as before.

Title: A process for separating ions by ion-exchange
IPC: B01J39/26
Filed: 1958-09-01
Abstract: Yttrium and rare earth metals present in solution as sulphates are recovered by precipitation with oxalic acid.ALSO:A cation-exchange resin bed, at least 80% saturated with a mixture of cations to be separated, is eluted with a solution of an aminopolyacetic acid complexing agent for said ions and successive portions of the eluate collected, whereby said ions are separated.  Where the mixture to be separated contains a number of different ions, of which those forming less stable complexes need not be individually separated, yields may be improved by recycling an intermediate fraction from which the complexing agent has been separated, or an intermediate fraction of the complexed solution may be employed as such as an eluant.  The column employed may have a greater diameter than is usual in such processes, e.g. of 4-20 inches.  Preferably the resin used has a particle size between 50 and 200 mesh (U.S.S.), and suitable column lengths are from 3-12 feet.  The preferred resin is a sulphonated polystyrene-divinyl benzene copolymer having a cross-linkage of 4%, it contains 4% divinyl benzene.  The invention may be applied to the separation of mixtures containing rare earth metals and yttrium, rare earth metals mentioned being La, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu.  Specified complexing agents are nitrilotriacetic acid, hydroxyethylenediamine triacetic acid, diethylenetriamine pentaacetic acid, diaminocyclohexane tetraacetic acid or preferably ethylenediamine tetraacetic acid in the form of a solution containing both tri- and tetra-basic alkali metal or ammonium salts and having a pH of 8-9.5.  The eluant for the final fraction may also contain an alkali metal or ammonium acetate and have a pH of 7-8.  The eluates may be acidified with hydrochloric, nitric or sulphuric acid to liberate the free complexing agent and the rare earths finally precipitated as oxalates.  If desired, prior to the method of the invention, dysprosium and lower rare earth metals may be eliminated from the initial solution by a process other than of ion exchange, or the fraction high in Ho, Er, Tm, Yb and Lu may first be separated by the method of the invention and a fraction containing the remaining metals collected and separated by a process other than of ion exchange. It is preferred to operate at 25-40 DEG C. for the separation of yttrium and ytter earth metals and at 60 DEG C. for terbium.
