Abstract: 1285803 Pipe connectors HYDROTECH SERVICES Inc 20 Nov 1970 [24 Nov 1969] 55429/70 Heading F2G Two pipes which may be misaligned are each connected to a connector and the connectors joined together. As shown in Fig. 7 pipes 73, 74 can slide within connectors 71, 72 which are joined by clamp ring 84 over their flanges 81, 83. The pipes 73, 74 can slide and rotate within the connectors 71, 72 but when the required position is found they are fixed relative to each other. An alternative arrangement for joining similar connectors 34, 35 is shown in Fig. 4. In another arrangement the connectors each have a flange attached obliquely at one end of their length, one of the flanges, Fig. 5B (not shown), has a number of holes (25) at a given pitch and the other, Fig. 5A (not shown), has four slots at the same pitch and extending circumferentially. Bolts are placed through the holes (25) and the connectors slid over the pipes to be joined. The slots in the second flange permit the rotation of the connectors relative to the pipes and each other so that the axes of the connectors can be misaligned to the same extent as the pipes to be joined. The abutting flanges are then secured in that positioning by tightening nuts on the flange bolts. In Fig. 8 the connectors are joined by a ball-andsocket arrangement. Further modifications of this, Figs. 9, 10 (not shown), employ connectors each having a socket identical to that shown fitted to connector 88 and the connectors are joined by two balls, identical to those shown, joined back to back. The balls may incorporate further adjustment by being joined back to back using oblique flanges of the type described above. The double ball-and-socket arrangement can join not only pipes whose longitudinal axes intersect but also those whose axes are parallel. In each of these arrangements the pipes are rigidly joined to the connectors by the arrangement shown in Fig. 8 in which there is a piston 93, seals 95, grips 97 (circumferentially spaced) and a fixed block 98. Fluid pressure is applied to the piston 93 via inlet 92 which causes grips 97 to engage the pipe 86 and the seals 95 to be subsequently compressed. The fluid used is preferably an epoxy resin which will harden and a permanent joint results.

Cocoa beans are first subjected to a vacuum treatment, are then impregnated with water or alkaline solution at atmospheric or higher pressure and at a suitable, preferably elevated, temperature, and following impregnation are 'subjected to a further vacuum treatment to obtain rapid drying. In the embodiment shown, the beans are contained in a hopper A and the water or solution in a tank B. These are adapted to supply two cylindro-conical reaction containers C alternately. Associated with each container C is a valve 1 for controlling the bean feed, a valve 2 for controlling the feed of water or solution, a valve 5 to control communication between the container and a vacuum apparatus which may also be adapted to pressurise the container to above atmospheric  pressure, if desired, and a heating coil 6 through which steam may be passed under control of valve 8. Condensate may be removed by operation of valves 9. After admission of a batch of beans to the container, the container is evacuated. Atmospheric pressure is then restored and the water or solution fed in. During impregnation the mixture is kneaded by a spiral 10 to which is secured a scraper 11, the spiral-scraper assembly being rotated by a motor 14 through worm gear 13. The container Is heated by the coil 6 during impregnation and subsequent drying of the beans which is assisted by again evacuating the container, after which a valve 15 is opened to discharge the treated beans.

Patent GB-596605-A (GB)
Abstract: 596,605. Centrifugal separators. EDWARDS, M. L. May 24, 1945, No. 13023. [Class 23] [Also in Group XXVI] A device for centrifugally reducing foam and separating its constituent parts, comprises a rotating casing 28 containing a chamber, a fan 24 for inducing a flow of foam into the chamber and means within the chamber for applying centrifugal force to the foam. In one arrangement, Fig. 2, the casing is mounted under the top of a tank containing oil for an aircraft being driven by an external electric motor. When foam forms above the oil surface, the fan and casing are rotated and vanes 34 lead foam into the casing which contains further vanes. The foam passes through screens 32, having baffles 33, the separated gas being driven out by the fan 24 into the tank, which is provided with a vent pipe to atmosphere, the oil running down the inside wall of the chamber and dropping back into the tank or being flung off an edge 31. In a modification, an axial flow pump on a shaft of large diameter, is mounted in the inlet of the chamber. Ports in the chamber wall allow the oil to pass out into the tank. In a further arrangement, Fig. 6, the rotating chamber 79 is mounted in a casing 54 outside the tank 51 which has a vent pipe 52 which leads foam into the chamber. After separation, gases pass to atmosphere by way of a port 61 and the liquid builds up on a wall 79 and flows downwards through openings 87 leading to a volute 94 leading back to the tank 51 by way of a check valve. The volute may contain a centrifugal pump. The chamber 82 contains vanes attached to the wall 74. Baffle rings 95, 96 prevent splashing from liquid entering the volute area 89. Baffle rings 72, 97 are also provided. A drain 99 leads liquid to outside the casing 65 of the driving motor. Walls 102, 63 prevent oil passing down the shaft of the motor.
