Title: Face seal structure
IPC: F04B9/117
Filed: 1969-04-28
Abstract: 1,271,143. Reciprocating pumps. E-C CORP. April 28, 1969 [Nov. 6, 1968], No. 21572/69. Heading F1A. A device for raising the pressure of a lowpressure first liquid by a high-pressure second liquid, e. g. process liquids from an exchange crystallization sea-water desalination process, comprises a rotor 10, e. g. driven by an electric motor, and a stator 32 with liquid connections 55, 76 and 64, 79 which sequentially register with rotor bores 16, 18 containing ball pistons 28, 30, sealing between the rotor and stator being effected by plates 60, 86 formed with arcuate ports and located by the stator and provided with sealing elements engaging the rotor and stator, the sealing elements defining areas exposed to pressure which are related, as claimed, to provide a biasing force on the plates. Low-pressure liquid is supplied at connection 55 and high pressure liquid at connection 79, connection 76 being connected to atmosphere and connection 64 to a pressure storage means. In the position shown, piston 28 is moved to the left by incoming low-pressure liquid. On rotation of the rotor, when bore 16 communicates with connections 79 and 64, high-pressure liquid from connection 79 moves piston 28 to the right and discharges the liquid at increased pressure through connection 64. Plates 12 and 14 are secured to the rotor and provide the rotor surfaces engaged by the seals on plates 60 and 86. The sealing element 102, Fig. 7, on the rotor side of each plate 60, 86 comprises a thin sheet of high shear strength and low coefficient of friction, e.g. polyamide resin impregnated with graphite, and is bonded to the plate 60, 86 by adhesive. Alternatively, the plate may be made of the same material as, and formed integrally with, the seal element. The element is located by plate ribs 100, 103. The other side of each plate has O-ring seals 110, 114 and 118 around the plate periphery, central aperture 90 and high-pressure port 92, respectively. The seal 118 also encloses parts of the lands between the arcuate ports in the plate so that the hydraulic pressure at port 92 acts over a larger area to produce a small resultant force acting to continuously bias each plate 60, 86 against the rotor even when bores 16 and 18 are traversing the lands between the plate ports.

Patent GB-700234-A (GB)
Title: Improvements in or relating to method of bleaching petroleum or fatty oils
IPC: C10G25/06
Filed: 1949-08-24
Abstract: <PICT:0700234/III/1> Petroleum or fatty oils are bleached with solid adsorbent, first by passage through a mass of partially spent adsorbent and then by mixing with fresh adsorbent, the second stage being carried out at low pressure (e.g. 0.5-4 inches of mercury) and the adsorbent separated after the second stage being used as the partially spent adsorbent in a subsequent operation of the process. If desired, there may be a preliminary mixing with fresh adsorbent, and steam stripping at low pressure to separate air and moisture from both oil and adsorbent, before the contact with the partially spent adsorbent; the adsorbent used in this preliminary stage is filtered out by the passage of the oil through the mass of partially spent adsorbent in the first stage.  Fatty oils mentioned are animal, vegetable and marine oils such as cottonseed, soyabean, peanut, corn, sunflower seed, sesame, coconut and palm oils and also fats such as lard and tallow.  The solid adsorbent may be carbon black or a bleaching clay such as fullers earth.  In Fig. 1, oil enters the upper portion of column C through pipe 4 and passes in counterflow to stripping steam from line 7.  Steam and volatile matter is drawn off by vacuum system V, while oil is withdrawn through line 8, heated in heat exchanger E and heater H, and passed to one of filters F1, F2 and F3, containing a cake of partially spent adsorbent.  The partially bleached oil is then fed through pipe 9 into heated mixer M where it is mixed with fresh adsorbent from supply tank S. The resulting slurry is passed through line 11 and sprayed into the lower portion of column C, where it is subjected to the action of stripping steam from line 7.  The slurry is then passed through pipe 16 to one of filters F1, F2 and F3, where the adsorbent is separated from the oil, thus leaving a cake of partially spent adsorbent in the filter. Bleached oil is withdrawn through pipe 17.  Apparatus is also described wherein centrifuges are employed instead of filters.
