    Abstract: Low temperature liquid storage tank of the internal heat insulating type having crack detecting means. The tank is provided with a primary impermeable layer located on the inner wall of the tank shell with a heat insulating layer interposed therebetween. A second impermeable layer is provided in the interior of the heat insulating layer. A layer of gas permeable sheet material is provided on the low temperature side of the secondary impermeable layer as well as on the high temperature side of the secondary impermeable layer and a circulating gas feed pump and a gas analyzing device are connected through connecting lines to the layer of gas permeable sheet material at the low temperature side of the secondary impermeable layer as well as to the layer of gas permeable sheet material at the high temperature side of the secondary impermeable layer, so that leakage of the low temperature liquid in the tank through possible cracks in the impermeable layers is detected by the circulating gas fed to the gas analyzing device by the pump through the layer of gas permeable sheet material.

    Abstract: 1,075,809. Centrifugal separators. MITSUBISHI JUKOGYO KABUSHIKI KAISHA. Dec. 7, 1965 [Dec. 7, 1964], No. 51901/65. Heading B2P. An apparatus for separating a mixture of liquids of different specific gravities comprises inner and outer cylindrical containers 1, 2 defining between them a space 4 into which the mixture is fed tangentially or substantially tangentially through a conduit 9 so as to whirl upwardly, as a result of which the lighter liquid flowing close to the inner container 2 is deflected by scoop plates 6 and directed into the container via axially spaced openings in its wall while the heavier liquid is discharged tangentially or substantially tangentially from the space 4 through a duct 10 at the upper end of the outer container 1, a valved pipe 23 being provided to discharge the lighter liquid from within the container 2. As shown, a continuous helical plate 3 is provided in the space 4 to define an upwardly helical flow path for the liquid mixture. The flow path is divided by at least one vertically positioned continuous helical plate 5 which serves to regulate the flow and to enhance separation by contact with the liquid. The plate 5, is positioned to a height lower than that of the passage and has a number of through-holes or cut-away portions 5 1 therein, Fig. 6 (not shown), to facilitate collection of the separated oil. The scoop plates 6 are curved against the flow direction and direct the lighter liquid through the openings and into riser pipes 7 discharging continuously into the interior of the container 2. Valves 11 are provided at the top of the riser pipes to regulate the discharge as desired from visual examination through an inspection window 12. Any heavy liquid entrained with the light liquid into the container 2 is separated therefrom by settling which is facilitated by the provision of perforated plates 8. The level of the interface between the heavy and light liquids in the container 2 may be regulated by an automatic level control means 22 associated with a level detecting terminal 20 and an electromagnetic valve 21 for the discharge of the heavy liquid. Instead of an automatic control means, a pair of cocks on the cylinder 2 may be used to regulate the interface level. To facilitate the separation of the light liquid in the flow passage 4, an inert gas may be blown under controlled pressure through ducts 14 of porous material, Fig. 1 (not shown). The gas pressure inside the apparatus is regulated by a valve 13. In a modification, the helical plate 3 may be dispensed with and the whirling obtained only by tangential feed of the liquid mixture into the passage 4. The apparatus is particularly suitable to separate oil from oil-contaminated water especially in marine vessels or land installations.
