Title: Treatment of molten ferrous metal
Inventor: COOK LESLIE
IPC: C21C5/32
Filed: 1960-11-28
Abstract: A process for the treatment of molten ferrous metal comprises feeding solid material in suspension in a low-pressure gas through the central passage of a lance having two concentric passages and feeding a high-pressure gas through the outer passage of the lance to provide a high-velocity jet directed towards the surface of the metal.  The high-pressure gas may be oxygen or another oxidizing gas and the low-pressure gas may be oxidizing, reducing or neutral, e.g. oxygen, carbon monoxide, nitrogen, propane, or coke oven gas.  The solid material may be slag-forming, e.g. lime or limestone, or may affect the composition of the metal, e.g. carburizing agents. p Dephosphorization may be accelerated by the addition of lime, iron ore, and graphite without affecting any alteration to the carbon content of the metal.  A solid charge may be melted by passing fuel gas through the central passage and high-pressure oxygen through the outer passage.

Abstract: 1,116,921. Valves. MARSHALSEA BROS. Ltd. 15 Jan., 1965 [16 Oct., 1963], No. 40860/63. Heading F2V. A high pressure relief valve comprises a housing 70 (Figs. 1 and 2 Comp.) containing a seat member 22 having a passage 28 communicating with a source of pressure fluid, the passage having an enlargement within which is mounted a poppet 29 adapted to prevent extrusion down the passage of a resilient pad 36 carried by a valve member 32 which seats against an extension 30 of the member 22. The valve loading comprises a series of Belleville washers 80 acting between a follower 81 and an adjustable seat 75, the latter seat being protected by a plastics plug 82. As shown, in the closed position the poppet head lies below the plane of the seat 83. In the embodiment shown in Figs. 1 and 2 (Provl.) a relief valve similar to that described above is incorporated in a valve controlling an hydraulic pit prop. This valve comprises a housing formed by two cylindrical members 1, 3 which locate between them a valve seat 45 for a main closure member 48 integral with a cylindrical member 40 slidable in member 1. The member 48 is urged to closure by the spring 18 of a non-return valve 17 controlling an inlet 2, and the relief valve is mounted within member 40 to control flow through a passage 52 provided in an extension 43 of member 48. In operation, fluid enters at 2 and flows past vanes 47 to an outlet 10 connected to the cylinder of the pit prop. On reaching a predetermined pressure it opens the relief valve and allows fluid to escape to an outlet (not shown) in passage 44. To open the main valve, a cam 60 is rotated by means of handle 62 and moves a ball follower 58 which abuts the end of the closure member. In a modification the handle 62 may control a valve in the inlet line, in which movement in one direction would open this valve to raise the prop whilst movement in the other direction would release pressure in the manner described to lower the prop.

Abstract: 1,151,575. Recovering alkylene carbonates from gas mixtures. BADISCHE ANILIN - & SODA FABRIK, A.G. 21 Sept., 1966 [22 Sept., 1965], No. 42117/66. Heading BIL. Alkylene carbonates which have been used to absorb C0 2  and H 2 S from gas stream are recovered from the gas stream by washing with water under pressure, 'the alkylene carbonate being subsequently removed by flashing the effluent with or without air stripping. The temperature of absorption is 20-70‹C and the pressure is preferably 25-100 atmospheres, while the preferred carbonate is propylene carbonate. In the embodiment shown in Fig. 1, a gas stream at 26 atmospheres enters sorber 2 at 1 and a stream of regenerated propylene carbonate absorbent enters at 3. Effluent stream A is washed with water enterchamber 10 at 15. Used absorbent is depressurized to 10 atmospheres in chamber 4, the effluent being scrubbed in chamber 11 with used water from chamber 10 before recycling as stream E to the sorber 2. The absorbent is further depressurized to 5 atmospheres in chamber 5 and to 1 atmosphere in chamber 6, the effluent streams B and C being washed with water in chambers 12 and 13 with a water stream entering at 16. Before recycling to the sorber 2, the absorbent is finally stripped with an air stream entering at 19, which is also contacted with both water streams in chamber 14 to concentrate them before they are passed by pipe 18 back to flash chamber 5. Gas streams treated by the process of the invention may be further purified by solutions of alkaline-reacting alkali metal salts.

Abstract: 1328563 Bucket brigade type stores PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 Sept 1970 [6 Sept 1969] 42248/70 Heading H3U A capacitor store or filter of the type in which the signal is passed via transistors along a succession of capacitors connected between collector and base or drain and gate of corresponding ones of the transistors, has a charge amplifier comprising the components T 6 , D 1 , C 33 , T 7  and C 4  arranged substantially as shown or a corresponding arrangement using field-effect transis tors. In operation, A is connected to a constantvoltage (e.g. a substrate) or, where the capacitors are integrated, to S 2  via a negative voltage source, not shown. B is connected to S 1 , through a voltage source if necessary. Clock pulses S 1  and S 2  are in opposite phase. The signal #V is represented in C 2  by the voltage E - #V (E being the clock voltage). When S 1  is positive, T 4  conducts so that C 3  and C 33  are charged to E volts. C 34  discharges through D 2 . When S 2  becomes zero and S 1  positive, C 2  is recharged to E volts from C 3  so that C 3  voltage becomes E - #V. C 33  is discharged to E - #V and C 34  is charged through T 7  to E. When S 2  again becomes positive, T 4  conducts so that C 3  is recharged to E from C 4  and C 4  voltage is reduced to (E - #V). C 33  is also recharged to E from C 4  accordingly the total voltage reduction across C 4  is (1 + C 33 /C 3 )#V and amplification has taken place between C 3  and C 4 . This can compensate for successive reduction along the chain of the available voltage swing due to the current transfer of the transistors being less than unity. The Specification described an integrated form of the circuit constructed in a manner similar to that in Specifications 1,271,154 and 1,271,155.

Filed: 1961-11-27
Abstract: 991,004. Temperature responsive actuating elements. AGIP NUCLEARE S.p.A. Nov. 27, 1961 [Nov. 29, 1960], No. 42284/61. Heading G1D. [Also in Division G6] A self-adjusting neutron absorber for controlling distortion and instability in the neutron flux distribution in a nuclear reactor comprises mobile and fixed neutron-absorbing surfaces, and elements connected directly to the mobile surfaces responsive to variations in the temperature of the coolant gas or variations in the neutron flux in the reactor such that these variations cause the elements to move the mobile surfaces relative to the fixed surfaces resulting in corresponding variations in the area of neutron-absorbing surface in the absorber. In one embodiment (Fig. 1), the mobile and fixed surfaces comprise the series 1, 2 of circular sectors of strongly neutron-absorbing material, e.g. boron steel or cadmium, the series 1 being fixed to a shaft 3 and the series 2 to the internal walls of a cylindrical container 4. The shaft 3, which is pivotally mounted between shock absorbers 14, 15 is connected to the central ends of a system 8 of three bimetallic laminae wound in spirals, the outer ends being secured to the container 4. Variations in the temperature of the coolant gas which enters through bores 6 and leaves through bores 7 cause the system 8 to rotate the shaft 3, maximum neutron absorption occurring when the series 1 is midway between the series 2 and minimum when the two series overlap. Where the absorber is sensitive to the neutron flux, one of the metals of the bimetallic laminae contains a fissile material, variations in the neutron flux causing variations in the energy developed by fission and hence in the temperature of the laminae. In a modification (Fig. 2, not shown), the variation in absorbing surface area takes place by relative rotary motion between a fixed series of cylindrical segments and a mobile series. In an alternative embodiment (Fig. 3), the variation of neutron absorption is effected by the relative translatery displacement of two coaxial tubes 1, 2 of strongly neutron-absorbing material. The tube 1 is guided by a shaft 5, supported by springed shock-absorbers 6, 7, along which it can slide. A system 8 of bimetallic spun discs 9, superposed and linked by means of rings 10, 11 (Fig. 3c), transforms temperature variations of the gas entering the absorber through bores 12 and leaving through bores 13 into longitudinal displacements of the tube 1.
