Title: Process of and apparatus for the production of steel or iron by the direct treatment of ores freed from gangue
IPC: C21B13/12
Filed: 1922-12-22
Abstract: 191,032. Constant, G., and Bruzac, A. Dec. 29, 1921, [Convention date]. Extracting. - In a process for the production of iron and steel as described in Specification 179,532, the ore is rapidly reduced in a . closed receptacle and the reduced metal simultaneously carburized therein by a reducing gas containing carbon monoxide. The reducing gases from a generator or a smelting furnace are passed through the dried ore, separated from its gangue, contained in one or more reduction chambers arranged above or in proximity to the smelting furnace, the ore being reduced and then allowed to fall or pass into the furnace without access of air. The reduction chamber A, hermetically sealed at the top and containing the dried ore, is provided in its inclined lower walls with downwardly inclined inlets for the entry of the reducing gases from the pipe C. The gases from the chamber A are drawn off, by a fan J, through a pipe E, a dust collector F, a cooler G and a meter I which ascertains whether the necessary amount of gases for the reduction of the ore has passed through the chamber A. A recording apparatus K is also provided to ascertain whether all the carbon monoxide in the reducing gas has been transformed into carbon dioxide. The chamber A may be lined internally and externally with refractory brick-work. The reduced material is allowed to fall into a sump B closed by a baffle joint which, when the material is to be transferred to the furnace, is replaced by a sleeve M resting on a water-cooled piece N. Before inserting the sleeve M the gases in the sump B are removed by a pipe. L connected to the fan J. To produce pure iron, a soft steel is first produced in the reducing chamber and then decarburised by the addition of iron oxide.

IPC: G05D3/12
Filed: 1922-12-27
Abstract: 213,012. Barr & Stroud, Ltd., and French, J. W. Dec. 27, 1922. Differential switches. -Retates to relays in winch the movements of one element are automatically followed by the movements of another element. The handle 9, which may be the one element, and the motor 12, which may drive the other element, are connected by a differential 10, 11 to a disc 1. If the handle 9 is rotated, the disc 1 is rotated and a slot 3 in it actuates the switch members 5, 7 causing the motor 12 to be driven one way or the other. This in turn brings back the disc 1 and switch arm 7 to their original position. To prevent the circuit tn the motor being opened too early when the disc 1 is rotated through more than one revolution by the handle 9, a retaining device such as the electromagnet 16 is adapted to hold the switch member displaced, being energized from the end of the first revolution onwards, through contacts 21, 22 which bear on a disc 19, provided with an insulating piece 20, and driven by the disc 1. In an alternative arrangement, Fig. 6, the insulating piece 20 is mounted on a disc 32 having fixed to it an elliptical wheel 31 gearing with another elliptical wheel 30 on the disc 19. In a modification, Fig. 3, a mechanical retaining device is used in place of the electromagnet 16. The lower end 16' of the switch member 5, 7 is here adapted to pass through a slot in one of two discs 28, 28<1> driven by the disc 1. Before the disc 1 has made one revolution, the slot in the disc 28 or 28<1> has passed the end 16<1> and the switch member is prevented from returning. Specification 213,320 is referred to.

Abstract: 1,035,488. Incinerators. BOSTON MARINE & GENERAL ENGINEERING CO. Ltd. Oct. 18, 1963 [Sept. 18, 1962], No. 35408/62. Headings F4B and F4W. An incinerator comprises a combustion chamber 10 provided with an opening 14 through which rubbish gravitates into the chamber 10, a grate 22 within the chamber 10, an ash compartment 24 below the grate provided with an opening in its base and a closure member 26 therefor and pipes 29 for injecting water into the ash compartment, the grate 22 comprising a number of bars which normally lie in one common plane but which can be moved relatively to one another to provide openings for the discharge of matter on the grate. The grate comprises a number of rotatably mounted parallel rods, Fig. 3 (not shown), provided with bars projecting perpendicularly therefrom. Each of the ends of the rods projecting through one wall 11 of the combustion chamber is attached to a link 33 except for the front rod which is attached to an elongated link 34. The upper ends of the links 33, 34 are pivotably joined to a common bar 35 so that small angular movement of the handle provided by the elongated link 34 causes the grate bars to oscillate slightly for riddling purposes whereas a large angular movement of link 34 rotates the rods to a position in which the bars are vertical thus providing gaps for the discharge of burnt rubbish into the ash compartment 24. A burner 37 is located at the rear of the grate 22, and burners (not shown) are disposed beneath the grate for initial ignition of the rubbish. A rubbish shoot 16 is mounted over the opening 14 and is provided with superposed dampers 39, 40 enclosing a space 41 in which rubbish is never allowed to accumulate. The dampers slide in guides 42 and are connected by a mechanical or hydraulic system which ensures that the upper damper opens first and closes last. Air is drawn into the space 41 through an inlet 43' and passes through a tube 44 to the incinerator chimney 17, thus cooling the space 41 and eliminating any fumes in the vicinity of the incinerator. A solenoid valve and a temperature responsive control may be provided to prevent ignition of the incinerator unless both dampers are closed, and to ensure that the dampers remain closed until the temperature in the combustion chamber falls below a certain value respectively. Two tubes 49, 50 disposed at the front of the combustion chamber supply air to the space above the rubbish on the grate. The base of the chimney 17 comprises an inner sleeve 46 surrounded by a casing 45 which is provided with a number of air inlets 47, Fig. 1 (not shown). A gas or oil fired after-burner 48 is mounted near the chimney exit of the incinerator.

Filed: 1956-11-20
Abstract: 829,580. Magnetic workholders. PANTON, J. R., and WEBB. A., [trading as PANTON & WEBB.]. Feb. 19, 1958 [Nov. 20, 1956], No. 35503 /56. Class 60. [Also in Group XXXV] A magnetic workholder comprising a block 1 of permanent magnets 9 mounted in a housing 2 for movement relative to a top workholding surface 4 thereof and a lower magnetic plate 7 is provided with sheet 8 of magnetic material which is interposed between the lower surface of the block and the plate 7 and has such dimensions that it transfers only part of the flux emanating from the magnetic block from one part thereof to another so that only a reduced amount of magnetic flux enters the lower plate. The block 1, which consists of alternate magnets 9 and magnetic flux transmitting pieces 10 insulated from each other by members 11 and held together by a bolt 12, is slidable between the upper and lower plates 4, 7 of the housing 2 ; the upper plate 4 consists of pole pieces 5 separated by non-magnetic material 6. One end of the bolt engages a U-shaped member 13 which cooperates with an eccentric 15 on a spindle 16 so that, upon rotation of the spindle by means such as described in Specification 829,101, the block is moved between its operative and inoperative positions. The thickness of the sheet 8, which is secured to the lower surface of the block 1, is such that the magnetic force between the block 1 and the plates 4 and 7 is substantially equal to enable the block to slide freely between the members. In the operative position, the magnets 9 and pieces 10 are aligned with the pole pieces 5 so that flux from each magnet passes through a pole piece, the work, a second pole piece, piece 10, the sheet 8 and plate 7 back to the magnet, and in the inoperative position, as shown, the pole pieces provide a direct path from the magnets to the pieces 10.

Abstract: 426,148. Converting. AKT.-GES. BROWN, BOVERI, & CIE, Baden, Switzerland. Dec. 19, 1933, No. 35700. Convention date, March 7. [Class 38 (ii)] A rectifier supplying an inductive load is protected against back ignition and short circuit by means which momentarily displace the ignition point of the anodes and cause the arrangement to operate as an inverter. In the form shown in the Figure the grid circuit of the discharge device 4 is normally disconnected, but when overload occurs a coil 8 supplied from a current transformer 7 completes the grid circuit so that the grids receive impulses from the distributer 13 which are approximately 180‹ phase displaced from the corresponding anode potentials. In a modification to obtain grid control for voltage regulation a further distributer is mounted on the shaft of the motor 14, this distributer being connected to the supply 9 during normal operation but disconnected and the distributer 13 connected when back ignition or short circuit occurs. Regulation is obtained by shifting the angular position of the distributer stator. If regulation is to be effected only within narrow limits a single distributer having two brushes angularly displaced 180‹ may be used. Specification 390,914 is referred to.
