Abstract: 1,185,495. Ion exchange. PERMUTIT CO. Ltd. 30 Aug., 1968 [12 June, 1967], No. 27063/67. Heading B1J. An ion exchange resin, for use in a process for softening or demineralising water by passing the water upwards through the bed of resin in an absorber, is regenerated by intermittently removing individual slugs of resin from the bottom of the absorber, each slug being caused to move upwards through a regenerator such that in the regenerator the slug forms a layer of greater depth than transverse dimension, the slug being regenerated by downward flow of regenerant and each regenerated slug being withdrawn from the regenerator downwards to and through an outlet from which it is returned to the top of the bed of the absorber. A plant suitable for carrying out the ion exchange and regeneration comprises an absorber 1, having water inlet 4 and outlet 6 and containing two slugs of resin 35 and 36, which is connected to a transfer vessel 8, of appropriate size to hold one slug of resin, into which the lowermost slug of resin 35 falls when valve 10 is opened, the space in the absorber being filled by a slug of regenerated resin 38 from an opentopped feed pot 29 after the remaining portion of resin 36 has settled, said feed pot preferably being furnished with vertical baffles 30 which cause the resin to move vertically downwards without any appreciable lateral movement. The slug of resin 35 is caused to move to regenerator 2 by means of a downward flow of water from pipe 11 and in doing so causes the slug 37 to rise in the regenerator tube. Regeneration of the slug 37 is carried out by means of regenerant fluid from distributor 15, the airflow being at pipe 25; after the resin has been backwashed and an opening valve 28, the upper slug of resin 37 is passed to the feed pot 29 by means of a flow of water from pipe 22.

Abstract: 284,748. Worssam & Son, Ltd., G. J., and Fox, D. P. S. Oct. 29, 1926. Bottling.-Relates to rotary bottling-machines of the type in which the rotary member carries a number of reciprocating bottle supports and the same number of filling-heads connected to a chamber containing air or gas under pressure and a supply of liquid. The filling-heads are controlled by plugs which are automatically operated and rotated in one direction to turn the fluid on or off. According to the invention the device for effecting the one-way rotation of the plug 4 comprises a star wheel having one or more sets of arms 5 and a prong 6 in rear of each set of arms. As a bottle 24 rotates in its support a pawl 14 is actuated against a spring 17 by the sliding rod 10 to cause a stop rod 16 to engage a prong 6 and turn the star wheel about its axis. Stops which co-operate with the arms 5 are mounted on the stationary annular ring 8 which is carried on supports 9. The initial position of the plug 4 and the star wheel are determined by a gravity stop-pawl 19 pivoted on the side 1<1> of the liquid container, which permits a prong 6 to only pass freely in the operative direction, the starting position being that in which the prong 6 is on the stop side of the pawl 19. The duct 21 and the port 25 in the plug admit the liquid to the bottle, the duct 22 and port 26 provide a pressure equalizing channel, and the duct 23 and port 27 provide an escape for air, gas or fob. An additional duct and port may be provided for the passage of air or gas under pressure from an independent source. A ball valve 29 in a retaining cage 30 controls the flow of liquid to the bottle.
