Title: Automatic reversing device for liquid measuring apparatus, especially for fuel dispensing plants
IPC: G03F7/24
Filed: 1930-12-22
Abstract: 375,752. Liquid meters. MARTINI & HœNEKE MASCHINENBAU-AKT.-GES., 122, Wilhelmstrasse, Berlin. Dec. 22, 1930, No. 38514. Convention date, Dec. 21, 1929. Void [Published under Sect. 91 of the Acts]. [Class 69 (ii).] In a liquid meter, especially for fuel-dispensing plants, the liquid is measured by cylinder in which a piston moves freely, the reversing of the piston being effected by a reversing device which is controlled by the overpressure occurring in the liquid duct leading to the respective sections of the measuring cylinder as soon as during operation the piston strikes an abutment in the cylinder. The piston B moves in a cylinder A provided with abutments at each end and connected by ducts 1, 2 with a reversing device comprising a valve C rotatable about a vertical axis. The valve C is moved intermittently during the operation of the measuring piston in a single direction by a controlling device D similar to that described in Specification 349,219 but turned upside down, and the reversing operation is operated by the pressure in the discharge duct 5. The floating regulator in Specification 349,219 is also replaced by a regulator E comprising a twin piston 12, 13 which is normally forced towards the left by a spring 14, the cylinder in which the piston moves communicating with the duct 5. The other side of the piston is connected by a pipe 16 to the supply duct 4 ; the other side is connected by a pipe 17 to the device D, but only when the orifices 15 in the end of that pipe are uncovered by the movement to the right of the piston 12, 13. When the piston B, in its movement, strikes an abutment in the cylinder A, the overpressure in the supply duct 4 is transmitted through the pipe 16 to the piston 12, 13 which is then moved towards the right, compressing the spring 14. The orifices 15 are thus uncovered and liquid flows by the pipe 17 into the device D which then effects the reversing operation as described in Specification 349,219. The regulator E is also controlled by the meter F, the shaft of which is provided with a disc 18 provided with a'cam 21 which moves up a spring-controlled rod 19 into the space between the twin pistons 12, 13 and prevents the movement of the latter. Leakage holes 43, 44 which connect with annular recesses 41, 42 are provided in the cylinder of the member E. The supply discharge and return ducts 4, 5, 9 are all filed up to the level G. The duct 4 discharges into the chamber 23 upon which a float chamber 24 is arranged, the float 25 allowing the escape of air through the pipe 26 and the duct 10. The upper edge 28 of a socket 27 fitted into the chamber 23 is on the same level as the upper edge 29 of a socket leading to the duct 5. Below the edge 28 the chamber 23 is connected by a duct 30 with the overflow pipe 9 and the duct 10.

Abstract: 859,706. Laminates. LJUNGBO, S. O. B., and LUNDIN, P. O. Dec. 12, 1957 [Dec. 18, 1956], No. 38696/57. Class 140. A laminate which may be used for camouflage purposes is formed by coating a net of strings or cords made of filaments, preferably of synthetic resin, with an adhesive for a plastic sheet material which sheet is then applied, preferably under pressure, whereby the adhesive penetrates around the individual filaments of the cords and anchors them to the plastic sheet. The adhesive used does not adhere to the filaments, but surrounds and binds them to the sheet, e.g. acrylonitrile butadiene rubber dissolved in mesityl oxide, P.V.C., or polymethyl methacrylate. The adhesive may be applied to the net as a solid and then melted thereon. In an example, nylon cord comprising 2000 strands of 3-denier which are only slightly twisted, is dipped in a P.V.C. adhesive composition and applied to one or more sheets of a polyvinyl plastic and passed between rollers; the product is then dried at 80‹ C. The sheet may have apertures, and small pieces of sheet may be applied. The sheet may also first be given a matt surface.

Abstract: 963,528. Reactors. UNITED STATES ATOMIC ENERGY COMMISSION. Oct. 29, 1962 [Dec. 13, 1961], No. 40858/62. Heading G6C. A method of removing heat and fission products from a plutonium containing molten fuel in the core of a homogeneous reactor characterized in that a coolant immiscible with the fuel is circulated through the core in actual contact with the fuel so that some fuel is entrained with the coolant leaving the core and subsequently separating the fuel and coolant whereby heat and fission products are transferred to the coolant. As shown, a vessel 1 of tantalum, closed at the top by a shield 37, has suspended from a top flange 2 a cylindrical structure 3 supporting a primary sodium coolant pump 4 having inlets 5, the pump outlet duct 10 being defined by a tube 11. A heat exchanger 6 surrounding the tube 11 has inlets and outlets 13,14 for the primary sodium, the cooled sodium passing to a surge chamber 15. A secondary sodium circuit for generating steam is connected at 20 to the vessel 1 and has annular inlet and outlet channels 16, 17 connected to the exchanger 6. The chain reaction may be terminated in an emergency by a rod 29 having a piston 22 normally held in the upper position in a housing 28 by fluid pressure in a conduit 21. On interruption of the pressure in conduit 21 the weight of sodium entering through a vent 24 drives the rod 29 down. Spiral baffles 31 at the lower end of the tube 11 impart a rapidly rotating movement to the sodium flowing through the duct 10, the sodium passing through a flow reversal region 32 and an annular duct 43 to the heat exchanger 6. The core 27 has a top shield 30 having peripheral fluid communication ducts 35 through which the molten fuel is continuously drawn in a jet pumping action by the flow of coolant. The fuel is an alloy of plutonium, cerium and cobalt. Thus in the region 32 the fuel is intimately mixed with the sodium and heat and fission products are transferred to the latter. Due to the rotational movement of the mixture imparted by the baffles 31 the heavy components i.e. the fuel, is separated in the region 34 and is returned by a baffle 36 and annular path 42 to the core 27. A breeder blanket 41 is provided.
