Title: Centrifugal separators for separating solids from liquids
IPC: B04B1/00
Filed: 1925-06-22
Abstract: 235,916. Laughlin Filter Corporation, (Assignees of Laughlin, W. C.). June 21, 1924, [Convention date]. Density and strainer separators combined.- Solids are separated from liquids in a density separator and the liquids are then passed through a strainer while the solids are removed by a rotary guide in the direction contrarv to the action of the centrifugal forces. The shaft 10 is supported in ball bearings and has a shoulder 15 and a tapering portion provided with a number of radial channels 16 communicating with the central channel 17 which forms the feed channel. Three discs 18, 25, 23 are held on the shaft by the nut 27 ; the circumferential spaces between the discs are closed and a plate 20<a> extends over the front of the disc 18 and is provided with a central outlet 21 for the solids. The disc 23 has outlets 24 for the liquids and the disc 25, liquid channels 26 leading to filtering material packed between screens held in position by a perforated plate 50. The disc 18 covers a number of partitions 31 between spaces which communicate with the main separating chamber 30 on one side and with the auxiliary chamber 32 on the other. A sleeve 13 on the shaft 10 carries radial arms 45 and arms 44 inclined to the radial as shown in Fig. 3. The arms 45 carry paddles 46 to enter the lateral extension 30a of the main chamber 30 to move the separated solids which are then guided to the central opening 21 by the arms 44. The sleeve also carries deflecting members 47 which intercept the incoming material and so prevent it from washing the solids back from the arms 44. The sleeve with its arms 44, 45, 47 rotates at a speed slightly different from that of the separating chamber. The material passes through the central channel 17 and the passages 16, 28 to the chamber 30, where the solids are thrown on to the circumference and the liquids pass on through the filter to the discharge outlets 24. Any solids stopped by the filter will be thrown back to the wall of the chamber 30. The mass of solids is moved by the paddles 46 and brought to the discharge opening 21 by the arms 44.

Title: Process for the deoxidation of ferrous metals with cyclic utilisation and regeneration of slags
IPC: C21C7/06
Filed: 1935-06-04
Abstract: Ferrous metals, i.e. iron, iron alloys, and steels, are deoxidized by treatment with fluid acid slags containing not more than 5 per cent of iron oxide and between 5 and 30 per cent of manganese oxide, the ratio of the manganese oxide content to the iron oxide content being greater than 4.  The content of the slag in iron oxide and manganese oxide must be low enough for the slag to retain, under the operating conditions, its power to extract iron and manganese oxides from the metal.  After the deoxidation the slag is regenerated to restore the iron oxide to a value below 5 per cent, the manganese oxide to a value between 5 and 30 per cent, and the manganese oxide-iron oxide ratio to above 4.  The regeneration preferably comprises a reduction of the iron oxide by means of a reducing agent followed by a replacement of part of the exhausted slag by fresh acid constituents, e.g. silica, this replacement being sufficient to restore the manganese oxide content to the desired value.  In treating Thomas steel which contains a small amount of basic slag from the refining operation, the same basic elements, e.g. calcium and magnesium oxides, are added to the deoxidizing slag in such proportions that the replacement of exhausted slag by fresh acid constituents also serves to restore the content of basic elements to their original value.  By increasing the manganese oxide content of the slag within the given limits the extraction of manganese from the metal undergoing deoxidation can be avoided or manganese may be introduced into the metal by reaction between the iron of the metal and the manganese oxide of the slag.  In the latter case it will be necessary to add manganese oxide during the regeneration. Silicon may also be introduced into the metal during deoxidation by reduction of the silica of the slag.  The exhausted slag may if desired be poured back into a mass of the original slag from which it was taken and the whole mass subjected to the regeneration treatment.  In the deoxidation the slags may be used in the molten state and intermixed violently with the metal or they may be used in the solid state in a ladle or furnace.

Abstract: 350,219. Control of motors ; drum controllers. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.- (Cutler-Hammer Manufacturing Co. ; Milwaukee, Wisconsin, U.S.A.) May 28, 1930, No. 16443. [Class 38 (iii).] Travelling to predetermined limits.-In driving mechanism in which a motor drives an object to or between limits through a driving connection which is quickly interrupted upon a given electrical condition in the motor, automatic means are provided to prevent the interruption except during the final movement of the object into a limit. As shown in Fig. 1 a motor 4 drives a valve through sun-and-planet gearing 3, when the outer ring 3c is looked by a latch 7. When a drum controller 13 is moved to its " close" position the motor is fed through coils 32a, 33a of relays 32, 33, and at the same time a restraining coil 32b is energized through a limit switch 11. The relay 32 thus remains closed irrespective of the motor current, and energizes coils 10, 15, the former causing the latch 7 to lock the ring gear 3c with a hammer blow and the latter causing a relay 14 to lock the controller in its " close " position. When the valve is closed the limit switch 11 is opened, and the coil 32b de-energized so that the excessive current in the coil 32a due to the stalling of the motor is able to open the relay 32. The coils 15, 10 are consequently de-energized so that the driving connection between the motor and the valve is interrupted, and the controller drum returns to its " off " position. When the controller , 5 is moved to its " open " position the operation is the same except that a limit switch 12 and the relay 33 are actuated. Indicating lamps S1, S2 are provided. In a modification, Fig. 3 (not shown), the coils 15, 10 are energized when the motor speed is above a certain value, the limit switches 11, 12 operating on a relay which places resistance in series and in parallel with the motor armature so that the speed of the motor is reduced and the coils 10, 15 de-energized.
