Abstract: 973,021. Pipe couplings. PACIFIC COAST ENGINEERING CO. Aug. 1, 1962, No. 29616/62. Heading F2G. In a ball-and-socket pipe coupling a ring 21 slidably encircles the ball section 11 about the crown of that section and has an end adapted to abut the end of the socket section 1, the ring providing substantially the entire bearing surface for the ball section. The means for drawing the ring and socket sections into abutment include a plurality of wedge hooks 31 disposed in spaced relationship about the periphery of one of the opposing socket and ring sections in overhanging relationship to the other section and a corresponding number of wedges 35 similarly distributed about the periphery of the said other section and adapted to wedge in the wedge hooks. As shown, the socket carries racks 41 engageable by a pinion 49 rotatable on a pin 47 and attached to a handle 53; the latter is fitted into a hole 45 to provide relative rotation between the ring and socket sections initially to bring the wedge hooks and wedges into registry. A sealing ring 69 is forced into sealing engagement with the ball section by pressure of the fluid flowing through the joint. A pin 59 is inserted between the teeth of the rack 41 to prevent accidental uncoupling.

The formation of scale on the heat transfer surfaces of an evaporator for saline water is reduced by the removal of magnesium ions and calcium ions from the feed water by a monovalent salt of an ion-exchange resin. The bivalent ion-enriched resin is regenerated by means of the residual water discharged from the evaporator. Sea water is passed continuously via line 1 and inlet 3 into vessel 2, where it passes upwards counter-current to cation-exchange resin. The softened water, which now contains only monovalent ions, is passed through line 5 into evaporator 6. The resin emerges continuously from the bottom of vessel 2 enriched in calcium and magnesium ions and is pumped via line 14 as a slurry of resin and sea water on to the perforated conveyer belt 15. The sea water in the slurry drains from the conveyer belt 15 into the feed water line 1 via line 16. The dewatered resin is fed into the top of vessel 7 and descends in counter-current contact with concentrated brine solution withdrawn from the base of evaporator 6 and passed to vessel 7 via line 12. The waste brine from vessel 7 leaves via outlet 18. The regenerated resin is pumped via line 8 as a slurry of resin in brine from the bottom of vessel 7 up to the perforated conveyer belt 10. The brine in the slurry drains into line 11 and is returned to vessel 7 via the junction with line 12. The dewatered resin on belt 10 is then fed into the top of vessel 2 for further use. A suitable resin for this purpose is the sodium salt of a sulphonated polystyrenedivinyl benzene.
