Patent GB-1003953-A (GB)
Title: A process and apparatus for refining pig iron
IPC: C21C5/32
Filed: 1962-02-08
Abstract: <PICT:1003953/C6-C7/1> In a process for refining iron in a solidbottomed converter, the charge is first blown with oxidizing gas through a lance with the converter in an upright position and stationary, slag forming materials such as lime and iron oxide being carried in suspension in the gas, or fed through an auxiliary duct in the lance.  The slag may be rendered more fluid by directing on to it a flame of oxygen and gaseous fuel. Sodium carbonate may be suspended in the oxidizing gas, or may be added with a tar binder through a separate spout in such a way that completion of fusion coincides with the end of the first stage blowing.  The latter point is reached when the carbon content reaches 0.7-1.7%.  The slag is then removed, and the converter turned down and rotated on its axis, e.g. at 20-50 r.p.m. while charge is blown again with oxidizing gas, which may contain lime and/or sodium carbonate and iron oxide in suspension, the lance and converter being so positioned that for the earlier part of the beam the gas penetrates deeply into the metal, while for the final stage the penetration is less deep and the gas flow is reduced. A suitable converter arrangement is shown in Fig. 1.  The end of the first stage may be determined by sampling the bath and determining the carbon content by a magnetic method, or may be determined by monitoring the amount of oxygen blown in.  Reference has been directed by the Comptroller to Specification 789,258.

Title: Improvements in nuclear reactor power monitor
IPC: G21C17/10
Filed: 1960-02-11
Abstract: 878,536. Nuclear reactors; luminescent materials. GENERAL ELECTRIC CO. Feb. 11, 1960 [Feb. 13, 1959]. No. 4849/60. Classes 39(1) and 39(4). A method of monitoring the power distribution in a nuclear reactor having a plurality of channels through which a liquid coolant is passed, comprises the steps of collimating the penetrating radiation emitted from at least one of the flow channels, and measuring the intensity of the collimated radiation at a plurality of points outside the reactor vessel, the attenuation of the radiation varying with changes in the density and the temperature of the coolant through which it passes and the power level in the channel so that the collimated radiation has an intensity which is a direct function of the power level. The method is particularly suitable for boiling water reactors, and the reactor shown in Fig. 4 is provided with internal collimator tubes 160 aligned with the fuel channels. Each tube 160 is open at the end adjacent the fuel channel, closed at its other end, and closed intermediately, apertures being provided in the tube below the intermediate closure to allow the escape of coolant. One or more external collimator tube 162 containing a radiation detector 164 sensitive to fast neutrons and/or gamma rays are aligned with the internal collimator tubes, and the count given by the detector is a measure of the power level of the associated fuel channel. In Fig. 4 there is a single external collimator and detector mounted on a reciprocable arm which in turn is slidably mounted on a support ring 165. A further collimator 166 and detector is similarly mounted round the periphery of the reactor to determine the axial power distribution of the core. The internal collimator tubes may be omitted, Fig. 1 (not shown). The collimators may be of lead, boron steel, mild steel, or, if neutrons are detected, of hydrogenous plastic. For detecting fast neutrons a fission counter or a scintillation counter may be used. A scintillation counter may be made by mixing 1.5 grams of 8-25 micron size particles of zinc sulphide and 10 grams of polymethyl methacrylate moulding powder and moulding at 2,000 p.s.i. and 120‹C. to produce a cylindrical button about 1 inch in diameter and “ inch thick. The scintillation is detected by a photo multiplier tube placed adjacent the material. With gamma radiation scintillation counters may be used in conjunction with a sodium iodide crystal, or ion chambers and Geiger tubes may be used.

Abstract: 776,533. Regenerative heat-exchangers. BEAVIS, M. C. HARTNELL-. May 24, 1954 [Feb. 23, 1953, Nov. 25, 1953], Nos. 4945/53 and 32702/53. Class 64(1) Relates to counterflow regenerative heat exchangers comprising a matrix in the form of a cylindrical or conical annulus having sector-shaped through-passages containing heat transfer material swept alternatively by relatively hot and cold fluids which are carried to and from the matrix by ducts, relative movement being provided between the ducts and the matrix end faces. According to the invention, means are provided for maintaining the matrix at a substantially uniform temperature, e.g. as described in Specification 776,532, and seals extend between the matrix end faces and the adjacent duct ends, each seal comprising a backing plate defining an inlet for one of the fluids and an outlet for the other fluid, and a sealing plate in frictional sealing engagement with the matrix end face having an aperture therein in alignment with the heated fluid outlet or the heating fluid inlet and being sufficiently wide on each side of the aperture to cover at least one matrix through-passage. Where the two heat exchanging fluids are at substantially different pressures means are provided whereby one or more matrix through-passages about to enter or leave either the high or low pressure zone are put momentarily into communication with a passage or passages which have just been cut-off from that zone to reduce carryover from one fluid stream to the other. Fig. 2 shows a typical sealing arrangement at one end of a rotary matrix type regenerator. A stationary casing 12 surrounds the rotor containing heat transfer material 4 embodying baffles 5 to protect the rotor structure from the effects of the hottest fluid. A backing or end plate is connected to the casing 12 and is apertured to provide sector shaped areas 1, 2 for the high pressure and low pressure fluid respectively. The high pressure seal comprises a sector shaped sealing member 13 of metal or metal backed, and a thin stainless steel partition 15 extending between the seal 13 and the backing plate 3; the seal is loaded by utilizing the pressure of the high pressure fluid augmented by springs. Fluid leakage between the rotor and its surrounding casing 12 is prevented by a spring loaded, peripheral, low pressure seal 17. The heat transfer material 4 may be of the kind described in Specification 750,303.

IPC: B61L23/12
Filed: 1921-02-15
Abstract: 175,535. Duff, F. H. Tern-. Feb. 11, 1921. Staff, tablet, and ticket systems.-The levers for operating points and signals on single-track systems are normally locked and are released for operation and the token apparatus is locked by actuation of a lock into which the token is inserted and of which the token forms an essential operative member. After releasing the levers, the token is withdrawn and is handed to the locomotive-driver as usual. The levers are locked by a spring-pressed bolt L which engages a plunger P, and the tail of the bolt L locks the token apparatus to prevent its further operation until the bolt L is reset. The bolt L is retracted by rotation of the tumbler T, the shank of which projects into a hollow boss F and is shaped to fit over a hole in the tablet. Feathers on the inside of a tubular key K engage slots in the periphery of a tablet, which thus serves to transmit rotary motion from the key K to the tumbler T. After withdrawal of the bolt L and operation of the plunger P the tablet may be removed and handed to the driver. The plunger P is re-locked on replacement by the spring S which restores the bolt L. Fig. 11 shows a lock-operating device for use with a ball-token. A cylindrical member K1 with an opening to receive the token and a plunger Z with a handle H slidable axially, is pivotally mounted on studs SS so as to be movable for insertion and removal of the token. After insertion of the token which has circumferential grooves to engage feathers on the cylinder the handle H is pressed inwards and first engages the token afterwards moves axially the cylinder K1 and then rotates it so that the projecting shank of the tumbler T registers with the groove in the token which is then pressed into engagement therewith and the cylinder K1 with the token and tumbler is rotated backwardly to release the levers. The token mav then be withdrawn for use in the usual manner.
