Title: Method for separation of ion exchange resins
IPC: H01H23/02
Filed: 1973-01-30
Abstract: 1406354 Separating ion-exchange resins ECODYNE CORP 30 Jan 1973 [1 March 1972] 4610/73 Heading B1J In a method for the separation of cationexchange resin from anion-exchange resin in a separation zone, a liquid having a density intermediate between the densities of the cation-exchange and anion-exchange resins is delivered to the resins in an amount sufficient to permit the anion-exchange resin to float and the cation-exchange reisin to sink, the said liquid being delivered continuously to the resins and withdrawn intermittently from a lower portion of the zone. The liquid may be an aqueous solution of sodium hydroxide which simultaneously regenerates the anion-exchange resin. Sodium sulphate solution or an organic liquid may also be used.

Title: Improvements in or relating to pulverisers
IPC: F23K3/00
Filed: 1924-02-25
Abstract: 212,888. International Combustion Engineering Corporation, (Assignees of Bell, J. E.). March 15, 1923, [Convention date]. Impact pulverizers. - A pulverizer for coal &c. comprises a hollow impeller which is rotated at high speed and has an open throat leading to a series of impeller blades adapted to pulverize the material fed through the throat and to throw the pul. verized material progres - sively without retrogression to a receiver placed adjacent the periphery of the impeller. As shown in Figs. 1, 2, and 3, the coal passes from a bin by a pipe 7 to a casing 8 containing a feed-screw 9 which delivers it into a throat 10 leading to the throat 11 of a runner or impeller 12 mounted within a casing 13 and on a rotary shaft 14 which may be driven by a steam turbine B. The impeller has long blades 15 and short blades 16; and adjustable impact-plates 16<1> are arranged nearly at right-angles to the line of flight of the particles discharged from the impeller and inclined slightly so that the pulverized coal after impact is. carried away 'from the blades into the peripheral receiving-chamber 17 formed in the casing 13. The impeller acts as a fan to carry the pulverized coal from the chamber 17 through pipes 18 to a cyclone separator C, the fine particles passing therefrom by a pipe 19 to a cyclone separator D while the heavier particles falling to the bottom of the separator C are discharged into the feed-casing 8 by means of feed-mechanism 20 driven through gearing 33 from the shaft 9' of the feed-screw 9. The air is returned by a pipe 20' to the feed-pipe 7, and by a branch 21 to the throat 10. An annular rib 23 on the upper side of the impeller prevents particles from lodging between the impeller and the casing; and to prevent suction of descending particles out between the throats 10. 11, a lip 10<1> of the throat 10 projects into the throat 11 and packing 24 is provided. The shaft 9<1> is driven through cone-pulley mechanism 30 from a shaft 29 which is driven by a belt 28 from a shaft 27 driven through worm gearing 25, 26 from the shaft 14 of the impeller. Governor mechanism 31 for controlling the supply of steam to the turbine B is operated by a belt 32 from the shaft 27. In a modification, Fig. 4, the major portion of the air is supplied by a variable-speed fan F to which the return pipe 20<1> leads and from which there is a connection to the inlet 34 in the upper part of the receiving-chamber 17. The discharge outlet 35 opens from the bottom of the chamber 17 at a point approximately below the inlet 34. In another arrangement, the apparatus is horizontally disposed, and the air inlet and the discharge outlet from: the receiving- chamber are located at the bottom and in alignment.

Abstract: 548,664. Aerating liquids. ELECTRO-CHEMICAL ENGINEERING CO., Ltd., and GIBSON, A. R. April 16, 1941. No. 4954. [Class 14 (i)] An apparatus for introducing air or other gas or gases in a finely divided state into liquids, and more particularly for aerating liquids containing solid matter in solution or suspension for the purpose of effecting chemical changes therein, such as the oxidation of zinc or ammonium sulphite, consists of a vessel A containing the liquid into which is wholly immersed a unit comprising a casing B having a constriction B<SP>1</SP> shaped. to. constitute a venturi throat,. and enclosing near its lower end a propellor pump E. The casing is supported from a bracket C<SP>1</SP> which also carries an air intake pipe D adjustable with respect to the throat B<SP>1</SP>, the pump shaft E<SP>1</SP> running through this pipe to a bearing E<SP>2</SP> supported by a second bracket C<SP>2</SP>. This shaft is. driven through a clutch F<SP>1</SP> from a motor F mounted on a third bracket C<SP>3</SP>. In a modified construction, the venturi. throat is at the top of the casing and the pump immediately beneath the lower end of the venturi outlet cone, and the lower end of the casing, which may rest on the bottom of the vessel containing the liquid, is provided with a fitting which deflects the gas-liquid mixture horizontally, to avoid turbulence at this region and to assist in scavenging the base of the vessel.

Filed: 1939-02-15
Abstract: 525,150. Gasmeters. BENNETT, T. W. Feb. 15, 1939, No. 4961. [Class 54] The meter casing 3 is divided by vertical partitions 4 into an inlet chamber 7, an outlet chamber 8, and a centre chamber in which a piston 9 is reciprocable in a cylinder 5 attached to the partitions 4 by a horizontal plate 6. The chambers 7, 8 communicate with the spaces above and below the plate 6 by arcuate ports 27, 28 controlled by disc valves 24 rotated through connecting rods 21 by vertical rods 19 connected to a horizontal bar 13 which is connected to the piston 9 by tubular rods 11 sliding on vertical guide rods 29. The ports 26 in the valves 24 are arranged so that gas flows to the space below the piston while exhausting from the space above it, and vice versa. The bar 13 is formed with a flattened loop 14 operating a crank 16 on a shaft driving the consumption indicator 18. The valves are given an impulse at the dead centre positions by the passage of their crank arms 23 past spring fingers 32. A similar spring finger 34 gives an impulse to the crank 16. The casing 3, partitions 4 and cylinder 5 may be formed of synthetic resin or other mouldable substance.

Abstract: 245,305. English Electric Co., Ltd., Ayres, W. E. M., and Hassler, E. H. H. Feb. 24, 1925. Testing balance of rotary apparatus. - Comprises a balanced float upon which the body under test is rested and which is carried on a bath of liquid the disturbance in level of the float indicating the degree of out of balance and the position and amount of the mass to be added to restore balance. A circular float 1 with a hemispherically-shaped under side and previously balanced floats upon liquid in a bath 2. The float is provided with adjustable spirit-levels 8, 9, 10 in horizontal lines at right-angles to one another. The float is also provided with carriers 6 having stepped surfaces 7 to receive the body to be tested which is adjusted until a vertical line through its geometrical centre or its centre of rotation passes through the centre of gravity of the float. The levels are first adjusted to zero and after the body is placed in position the reading of the levels will indicate the degree and position of the out of balance mass which may be corrected by applying masses to the body to restore balance. The level of the float may be adjusted by means of counterweights on fine threads. Optical means may be provided for indicating the change in inclination of the float. Other devices such as adjusting screws may be provided for locating the body correctly on the float.
