Title: Method of recovering an unburnt waste gas produced in an oxygen top-blowing converter
IPC: C21C5/38
Filed: 1963-04-22
Abstract: A method of recovering CO-containing gas from an oxygen top-blowing converter 1 comprises, during the start of the blow stage, i.e. for the first 4 to 8 minutes, introducing air into the clearance between the furnace mouth 3 and a vertically movable skirt 4 and burning the gas produced with the air, the resulting burnt gas and residual air being vented to atmosphere via stack 12, and during the intermediate part of the blow stage restricting the input of air by gradually lowering the skirt 4, e.g. to within 10 <PICT:1040624/C4-C5/1> cms. of the mouth 3, and collecting the gas produced, unburnt, in a vessel 10.  The end of the blow stage is operated under conditions similar to the start.  Additional methods of restricting air input which are employed comprise gradually developing a positive pressure in the cooler 6 by means of a control valve 8, and forming a seal between the mouth 3 and the skirt 4 by means of nitrogen jets 2 which also serve as explosion-preventing means.  The amount of air introduced into the converter during burning is adjusted so that the total gas, i.e. air plus gas produced, lies in the range 1/3 to 2/3 of the maximum gas produced at the height of the blowing period, see Fig. 2 (not shown), to maintain constant load on the fan 9. An inert gas is added to the gas produced just after starting recovery and just before finishing recovery to keep the total gas recovered at the desired volume.

Title: Improvements in or relating to apparatus for separating solids from suspension in gases
IPC: B01D45/08
Filed: 1935-06-04
Abstract: 457,784. Dust separators. WARING, H., 94, Cambridge Road, Blundellsands, Liverpool, and GOODLASS WALL & LEAD INDUSTRIES, Ltd., 3, New London Street, London. June 4, 1935, Nos. 16227 and 26632. [Class 23] Suspended solids are separated from gases while passing through a passage with baffles extending inwardly from the walls and alternately from opposite sides, so that the gas follows a zigzag path. The baffles form shelves for the collection of solids and have an inclination sufficiently steep to cause the solids to slip downwards under gravity if the flow of gases is discontinued or if the collected solids are disturbed. The apparatus consists of outer and inner conical vessels 11, 12 with cylindrical tops. The outer vessel has diametrically opposite inlets 14, 15 and vertical partitions 16, 17 divide the annular space between the vessels into two parts and ensure that the gases shall move down without undue cyclonic motion. The vessel 11 carries inward conical baffles 21 extending between outward conical baffles 22 carried by the vessel 12. A third conical vessel 32 may be added and this carries baffles on its outer side alternating with baffles on the inner side of the vessel 12. Conical baffles 35 on the inner side of the vessel 32 alternate with baffles on the central rod 27. Below the vessels 12, 32 is arranged a conical baffle 23 and a series of conical louvres 24 which permit dust to pass to the chamber 25. The gas enters at the inlets 14, 15, passes downwards between the vessels 11, 12 and is turned inwards and upwards by the cones and louvres 24. It passes upwards on both sides of the vessel 32, and between additional baffles 39, 40, 41 to the outlet 30. The separated solids drop through the louvres to the chamber 25; this action may be assisted by vibrating the apparatus. The first Provisional Specification states that separation may be caused by cyclonic action as well as by the changes of direction as the gases meet the baffles. Specifications 5710/11, [Class 51 (ii)], 109,315, [Class 46], and 441,900, [Group XXVIII], are referred to.

Title: Improvements in electric calling devices
IPC: H04L15/26
Filed: 1921-06-13
Abstract: 185,848. Whistlecroft, A. W. June 13, 1921. Selectors.-A calling-device, adapted to beoperated by a certain sequence of wireless im pulses of predetermined length, is so designed that signals of shorter or longer duration are rendered ineffective, whilst signals of the correct length are stored up, notwithstanding the intervention of jamming signals, and actuate the alarm when the predetermined number have been received. Energy from the receiving-aerial energizes an electromagnet g, Fig. 1, and rocks a pivoted arm h so as to free a friction disc d<1> mounted on a clockwork-driven spindle b. An impulse of considerable duration allows the governor e, f to gain speed and lift a sliding collar d sufficiently to close a contact j<a>, j, thereby energizing a clutch magnet k, and causing a spindle m to be rotated from a wheel l driven by the clockwork. An impulse of the correct length rotates an arm o, carried by the spindle m, sufficiently to close a contact (not shown) which energizes a magnet q, Fig. 3, and thereby moves a pawl t forward over one tooth of a sector u. Each time a, signal of the correct duration is received, this operation is repeated, until finally contact v, v<1> is closed and operates the alarm. Simultaneously, a magnet x is energized to release a locking-detent w, and allow the sector u to be reset by a spring u<1>. Should the received impulse exceed the correct duration, a second stop on the arm o energizes a cocking-magnet s, Fig. 3, which lifts the arm of the pawl t out of contact with the teeth of the sector u, and causes the return stroke to be ineffective in that it does not rotate the sector. Quite short impulses do not release the brake-disc d<1> sufficiently to allow the governor e, f to gather speed enough to close the contact j. The same contact that actuates the cocking- magnet s also energizes a safety magnet y, Fig. 1, which, by closing a contact z<b>, operates a magnet z<c> to bring down a clamping-arm zd and so stop the motor, thereby preventing the motor from running down during signal-impulses of very long duration. The contact z<b> is maintained closed until the armature z is freed from a stepped portion of the bar z<a>. This release is effected by means of an arm h<a>, when the armature-arm h is finally raised on the cessation of the signal. As soon as the motor is stopped, the contact j is broken, the spindle m is declutched from the wheel l, and the arm o flies back to its initial position under the influence of a spring. According to the Provisional Specification, the apparatus may be modified to work with timed intervals as well as timed impulses by the addition of another clock-work train set into motion by the registration of the first correct signal.
