Title: Improvements relating to ion-exchange processes and apparatus
Inventor: WATTS ANTHONY BERTRAM
IPC: B01J47/10
Filed: 1959-05-06
Abstract: 880,982. Ion-exchange. PERMUTIT CO. Ltd. May 2, 1960 [May 6, 1959], No. 15564/59. Class 46. The apparatus comprises a vessel 1 in which water is to be softened by cation - exchange, and the exhausted exchange material is to be moved in external circuit from the bottom to the top and then regenerated and rinsed in the vessel. The vessel is composed of four frusto-conical sections 2, 3, 4, 5 and an inverted conical bottom section 6. Within the lower part of the vessel a supply pipe 11 for the water to be softened leads to the hollow space in the core 7, the water flowing from this space in to the distri buter 9 and upwards through the ion exchange material in the annular space between the devices 9 and 10, which constitutes the treating zone. The part of the core 7 in this zone is conical, so that the bed of material in the treating zone is substantially constant in crosssectional area. The softened water leaves the vessel through the device 10 and a pipe 12, part of which lies within the hollow core 7. The exchange material can pass through (but not into) the device 9, but tends to be prevented from so doing by the upward flow of water out of the device 9, so that a water pocket forms under this device. From time to time the flow of water through the pipe 11 is stopped or reduced and a valve 21 in a by-pass pipe 13 is opened. The suction of the ejector 14 is applied and a slurry of exhaused material and water is drawn into the ejector 14 and delivered by it through a pipe 16 into the top of the vessel. The material already in the vessel moves downwards, and as the vessel widens, spreads out laterally in a uniform manner. The vessel contains a device 17 for the introduction of regenerant, which flows upwards to leave at the top through a pipe 18 controlled by a valve 19. The material is prevented from passing by a strainer 20. The regenerating zone is thus between the top of the bed and the device 17. The flows of water to be softened into the vessel through the pipe 11 and of softened water through the pipe 12 are controlled so that the former is a little greater than the latter, and a fraction of the softened water flows past the device 10. On passing the device 17 in its downward movement the material is rinsed by this fraction of the treated water, which flows upwards to join and dilute the regenerant introduced through the device 17. In the rinsing zone below the device 17 the material gradually spreads out laterally. The tapering part of the vessel may merge into a cylindrical part through which the material passes after spreading out, so that the regenerating zone may lie wholly within a cylindrical part of the vessel, or even partly in the tapering part and partly in the cylindrical part, and there is no need for a core.

Filed: 1921-06-06
Abstract: 164,339. American Cotton Oil Co., (Assignees of Phillips, C. 0.). June 5, 1920, [Convention date]. Cylinder machines; cooling and heating apparatus; delivery; feeding; cleaning apparatus; moulding soap.-Molten soap is charged into moulds and passed through cold brine but out of direct contact therewith; the preliminarily cooled cakes are then discharged from the moulds and subjected directly to the action of the cold brine; after which the cakes are preferably washed with water to remove brine. The soap is delivered from a jacketed hopper 16 by screws 20 to a cylindrical series of moulds 12 fitted with radial plungers 13 controlled by a series of adjustable fixed cams. After leaving the hopper, the moulds are first cooled exteriorly by a chamber 71 and interiorly by a brine spray and then pass into a tank 1 containing cold brine. Before entering the brine, the moulds pass beneath a strap or band 72 encircling the moulds, which strap prevents direct contact of the brine with the soap. The strap 72 is anchored at one end and is adjustable by a rod and nut at the other. The plungers 13 are moved by the cams to take up shrinkage of the soap. After leaving the strap, the plungers are forced outwardly by cams 38 to eject the cakes which are detached by rotating arms 45 and pass down a shoot 76 on to a conveyer 83 traversing a brine tank 82, and subsequently a fresh water tank. A brine spray assists the discharge of the cakes. Before passing beneath the hopper, the plungers are cleaned by a brush 79. A main shaft 27a drives the mould cyinder continuously through worm gearing 28, 29; the screws 20 through bevel gears 30, 31, arm 32, rod 26, ratchet mechanism 25, and bevel gears 24; the cams 38 through bevel gears 33, 36 and shaft 35, and the arms 45 through the shaft 35, gears 39, 40, shaft 41 and bevel gearing 43.

The arms 1<a> and 1<b> carrying the contact blades 2<a> and 2b are pivoted to the main spindle 3 on which is a crank 4 having a T-shaped end 5. On either side of the T-end 5 is a lever 7 which carries at its free end a spindle 8 elongated to engage cam faces 9 on the arms 1<a> and 1<b>. One end of a compression spring 10 is connected to the spindle 8 and the other is pivoted by a pin 11 to the casing or other fixed part. The levers 7 have arcuate slots 13 receiving the main spindle 3. Stops 14 engage the arms to limit their upward travel and means are provided for retaining them in the upper position. Rotation of the spindle 3 causes the levers 7 to pivot about the spindle 8 until the lost. motion between spindle 3 and the, bottom of slot 13 is taken up, whereupon the spindle 8 moves about spindle 3 as a fulcrum, slides up one cam face 9 of the arms into a position in which it bears on the other cam face and so positively raises the arms to break contact, if needs be, without the aid of the springs 10. The latter, however, will be compressed by the initial movement of the spindle 8 and, on passing the dead-centre, will give a quick break. The operation of " make " is similar. The improvements may be adapted to a switch having: any required number of poles.
