Title: Improvements in or relating to air-separators for fuel-pumping apparatus
IPC: B65B41/16
Filed: 1937-06-22
Abstract: <PICT:0478414/III/1> <PICT:0478414/III/2> <PICT:0478414/III/3> In a fuel-injection system for an internal-combustion engine, particularly for aircraft, two feed pumps draw from a suction tank, the suction pipe being pivoted within the tank, and deliver through an air separator to the fuel-injection pump.  The suction chamber of the fuel-injection pump is connected through a spring-loaded valve with the suction tank.  The air separator comprises a chamber 11a in which a rotatable member 51 fitted with a pendulum 54 is arranged.  Fuel is supplied through pipes 5 and 53 to the chamber and is delivered through bore 55 and pipe 7 to the injection pump.  The air separated passes through throttle 64 and passage 61 to the pipe 10a connected to the induction pipe. The throttle 64 is closed by a valve 66 actuated by a float 67 all the time the level in the separator exceeds a predetermined level.  In a modification, the delivery sides of the fuel pumps are connected to the suction tank through spring-loaded valves instead of the suction chamber of the fuel-injection pump.  In this system the air separator shown in Fig. 4 is employed wherein the air pipe 83 is connected to a sleeve 80 pivoted on an extension of the rotatable member.  A float 81 is fixed to the sleeve and the pipe 87 having orifices 88 and a ball 89 is connected to the pipe 83.  When the level of the fuel falls to a predetermined value, the sleeve 80 is rotated by the float 81 and the pipe 83 aligns with a port 85 so that air is discharged to the pipe 10a connected to the induction pipe.  The float is balanced by a weight 82.  Sealing liquid to the sleeve 80 is supplied through the pipe 70.  In a further modification, the air separator is divided into two chambers 97, 98.  Fuel is fed through bore 102, pipe 104 to chamber 97 and delivered through a bore in the rotatable member to the pipe 7.  Air and any fuel carried by it passes through the pipe 107 to chamber 98 where a second rotatable member is arranged.  The shaft 110 has a pendulum weight 112 attached and the sleeve 113 has an air pipe 114 and float 115 attached and also a fuel pipe 121. When the fuel level falls, the pipe 114 aligns with a port 116 and air is discharged to the pipe 10a and when the fuel level rises the pipe 121 aligns with the port 122 and fuel is discharged through pipe 7a to the feed pump suction.  Sealing liquid is supplied through the pipe 126.

Title: Expandable vinyl aromatic polymer particle composition and a method for preparing the same
IPC: C08J9/00

Abstract: 1528503 Expandable vinyl aromatic polymer compositions SEKISUI KASEIHIN KOGYO KK 28 April 1976 [28 April 1975] 17334/76 Heading C3C Expandable vinyl aromatic polymer particle compositions comprise 1-20% by wt. of a volatilizable expanding agent which does not dissolve or may swell the polymer particles and has a b.p. lower than the softening point of the particles and 0À001-0À05% by wt. of a sulphur containing compound of formula where R 1  and R 2  are C 12-18  alkyl groups, and R 3  and R 4  are C 1-4  alkylene groups. The sulphur compound may be a distearyl, dilauryl, ditridecyl lauryl stearyl or dimyristyl, thiodipropionate, or distearyl thiodiisobutylate. The compositions are made by (A) adding the sulphur compound to the polymer particles suspended in an aq. medium, heating the medium while stirring in the presence of the expanding agent and then cooling and recovering the particles; (B) adding a solution of the sulphur compound, a polymerization catalyst and vinyl aromatic monomer to an aq. medium containing a suspending agent, heating the medium in the presence of an expanding agent to polymerize the monomer and then cooling and recovering the particles; or (C) adding a solution of a polymerization catalyst in the monomer to an aq. medium containing a suspending agent, heating the medium above the decomposition temperature of the catalyst to polymerize the monomer, adding the sulphur compound and expanding agent before completion of the polymerization and after further polymerization, cooling and recovering the particles. In examples (I and 2) styrene was polymerized in an aq. medium containing the above sulphur compounds, propane, pentane, benzoyl peroxide, t-butyl perbenzoate, sodium pyrophosphate, sodium dodecylbenzene sulphonate and magnesium chloride; and in examples (3-5) styrene polymer was treated in an aq. medium containing the above sulphur compounds, propane, pentane and/or butane, sodium pyrophosphate, sodium dodecylbenzene sulphonate, magnesium chloride styrene, toluene, benzoyl peroxide, t-butyl perbenzoate, magnesium pyrophosphate and/or magnesium oxide, to form expandable particles which were dried, aged, pre-expanded with steam, aged again and moulded with steam to form cellular articles, e.g. cups.

Abstract: 1,247,629. Aerials. LICENTIA PATENTVERWALTUNGS G.m.b.H. 13 April, 1970 [7 May, 1969], No. 17425/70. Heading H4A. In a multiple dipole aerial arrangement, a plurality of transmitter/receiver units operable in a specified R.F. range are connected by individual feeders 4, 5, 6 to respective dipoles 1, 1; 2, 2; 3, 3, which are mounted on a mast colinearly above one another, and are insulated from one another. Decoupling means for the dipoles includes inductances inserted in the feeders near the lower ends and feed points of the dipoles, which form with stray capacitances parallel circuits resonant at pre-determined frequencies within the specified R.F. range. As described, the dipole members are circular or polygonal cross-section bars or tubes, the feeders are co-axial cables the impedances of which approximately match those of the dipoles, and the inductances are constituted by coiling the cables, as at 8, 9. With parallel wire feeders, the inductances are in the form of bifilar coils. Alternatively, the inductances may be in the form of wound ferrite cores. The mast may be a synthetic materials rod or tube upon which tubular dipole members are threaded and are then secured. With a tubular mast, the feeders may be run inside, and the inductances may be embedded by a casting process. The arrangement is particularly for mobile installations, such as vehicles and craft.
