Title: Improvements in or relating to self-priming centrifugal pumps
IPC: F04D5/00
Filed: 1951-09-10
Abstract: 691,513. Centrifugal pumps. SUGAR, A. S. Sept. 10, 1951 [Oct. 14, 1950], No. 21254/51. Class 110(i) A self-priming centrifugal pump which delivers one portion of the liquid by liquid-ring action and another portion by centrifugal action, comprising a single inlet port and separate outlet ports for the two portions, is characterised by the provision of a supplementary port situated forwardly of the discharge ports, through which discharged liquid is returned for priming purposes. The casing is in two parts 1 and 5, between which the impeller rotates in the direction of the arrows. The part 1 has an inlet port 2 and an annular channel 4 which is shallow at each end. The other part 5 has a spiral channel 6 which is shallow at each end and of nearly uniform depth elsewhere. Outlet ports 7 and 8 are provided for the liquid discharged by centrifugal action and liquid-ring action respectively. During priming, discharged liquid returns through an auxiliary port 10 to replace the liquid lost through the discharge port 7, so that a liquid ring is maintained for the removal of air from the pump. After priming, port 10 acts as an additional discharge port. In multi-stage pumps, only the last stage need be provided with a port 10. The front and rear surfaces of the impeller blades are of arcuate or other curved shape, and the blades are thicker at the suction edges than at the discharge edges.

Title: Improvements in and relating to airtight packages
IPC: B65D81/20
Filed: 1949-08-18
Abstract: 666,799. Evacuated packages. WILTS UNITED DAIRIES, Ltd., and TAUNTON, G. June 7, 1950. [Aug. 18, 1949] No. 21470/49. Class 94(i). A method of evacuating an airtight sealed package comprises bringing the wrapper into contact with a suction member having an orifice therein, applying suction to the orifice, piercing an exhausting hole in the wrapper through the orifice so that air is withdrawn from the package and sealing the walls of the wrapper together in the neighbourhood of the orifice so as to isolate it from the interior of the package. Sealing is effected by heat and pressure or pressure only according to whether the wrapper is made of heat-sealable material or has its inner faces coated with a pressure sensitive adhesive. Figs. 11-13 show the upper ends of packages formed by folding and seaming a sheet of wrapping material to form a bag, inserting a wedge-shaped piece of cheese and closing the open end of the bag by a seam 52. In Fig. 11 the final seal 53 encircles the exhausting hole 54 which has been pierced in -one wall of the bag; in Fig. 12 the final seal 55 extends across the bag below the hole, and in Fig. 13 the final seal 56 extends across the corner of the bag Apparatus for evacuating and sealing the package of Fig. 11 is shown in Fig. 1 and comprises a bedplate 1 supporting an apertured table 8 through which protrudes a suction member 9 connected by a pipe 14, valve 15 and pipe 17 to a vacuum pump. The valve 15 is provided with a release cock 18 and its operating plunger 19 is coupled by a link 20 to a lever 4 pivoted at 3 to the bedplate, the arrangement being such that progressive clockwise movement of the lever moves the plunger to establish communication first between the pipes 14 and 17 and then also between these and the release cock whereby the setting of the latter determines the degree of evacuation. The lever 4 is formed with an arm 5 carrying an electrically-heated sealing member 6, and its lower end is connected by a bar 25 to a spring 27. A leaf spring 23, secured to the bar by a clamp 24, is adapted to engage in a notch 29 in a pivoted spring-loaded hammer 21, whereby as the lever is moved clockwise the hammer is first cocked and then released to strike the lower end of a rod 35 which is slidable against a spring in a bore of the suction member and carries a V-section piercing tool 34, see Fig 5 (not shown). The upper end of the suction member is faced with rubber and the lower end of the sealing member is formed with a central recess and an annular groove to ensure a good seal. The table 8 is fitted with leaf springs 10 to hold the wrapper over the suction member, these springs being raised by a plate 13 on an extension 12 of the arm 5 when the lever is moved anticlockwise to allow the end of the wrapper to be inserted.
