Title: Waste Gas Dust Filtration
IPC: B03C3/88
Filed: 1967-08-02
Abstract: 1,192,071. Electrostatic precipitators. FRIED. KRUPP G.m.b.H. 2 Aug., 1967 [3 Aug., 1966], No. 35570/67. Heading B2J. Dust is removed from unburnt waste gas in an oxygen-blowing steel-making process, by passing gas through an electrostatic precipitator which has tubular collector electrodes 3, Fig. 1, associated coaxial discharge electrodes 4, an inlet pipe 1 and an exit pipe 7, with an exhaust fan 8. A gas-tight connection between the electrodes 3 and a top part 10 is provided by liquid-filled cups 12, 13. Dust is shaken into a space 2 by vibration of pistons 18 and conveyed by a paddle wheel 21 to a worm conveyor 22 and pocket wheel 23. To prevent danger due to explosive gas mixtures in the precipitator derived from the oxygen steelmaking process, the oxygen supply is withdrawn from the refiner if the fan 8 fails, and an injector nozzle 27 is switched in to force the gas quickly through the filter. The energizing current for the electrodes .is switched off by a switch 30. In a second embodiment, dust is removed from the electrodes by sprays 45, Fig. 3, and removed from the bottom of a water bath 43 by a paddle wheel 44.

Title: Improvements in or relating to the actuation of electric switches
IPC: H01H27/06
Filed: 1934-12-14
Abstract: 447,431. Latching switches. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and NORTON, R. W., c /o General Electric Co., Ltd., Witton, Birmingham. Dec. 14, 1934, No. 35961. [Class 38 (v)] A retractive switch for controlling a circuitbreaker comprises a handle 2 fixed on a shaft 4 having keyed to the other end a member 9 which is biassed to the central position by a spring 18 having arms 19 extending on each side of a pin 14 on the member 9 and a fixed pin 20. The shaft 4 carries bridging contacts adapted to engage pairs of fixed contacts 27 so that different circuits are completed when the handle 2 is moved to the left or right or is in the central position. A catch 11 is pivoted at 28 and is biassed to the central position, Fig. 3, by a spring 22. The catch has a claw 16 which, in the locking position shown, extends more than half way round a pin 15 on an arm 13 of member 9. An abutment 17 extends round about one quarter of the pin 15. From the position shown in Fig. 3, the arm 13 cannot be rotated anticlockwise due to the claw 16 restraining the pin 15. If the arm 13 is moved clockwise, the pin 15 engages the inner edge of abutment 17 and turns the catch 11 which is finally released and returns due to spring 22 to its central position. If now the arm 13 is returned to the central position, the pin 15 engages the outside of abutment 17 and displaces the catch 11. The arm 13 can now be turned anticlockwise until pin 15 slips off abutment 17 and rests on the end of claw 16. Then if the arm 13 is returned to the central position the pin 15 enters the catch and again assumes the locked position of Fig. 3, in which the arm cannot be moved anticlockwise until after it has been moved clockwise. This ensures that if the handle 2 has been moved to switch in the circuit breaker it cannot again be moved to the switching-in position until it has been moved to the switching-out position. A second catch lever may be provided acting in the opposite sense so that after movement in either direction the arm must next be moved in the other direction.

Title: Seal assembly
IPC: F16J15/32
Filed: 1963-09-12
Abstract: 1,062,175. Seals. B. F. GOODRICH CO. Sept. 12, 1963 [Sept. 13, 1962]; No. 36000/63. Addition to 979,792. Headings F2B and F2T. A seal assembly between a shaft 16 and a casing 18 surrounding the shaft comprises a sealing ring 10 in the form of an annular body 23 with a resilient annular diaphragm which is joined to it by a thin deflectable annular zone 25 and provides a continuous sealing edge 28 coacting with the shaft and of a diameter, when undeflected, smaller than that of the shaft, means, such as a nut 14, for causing the ring to engage the casing and also for deflecting the sealing edge into sealing engagement with the shaft, and further means 12 co-operating with the annular body for expanding the sealing edge to permit assembly of the seal; alternatively, according to the invention, the sealing ring is mounted on the shaft, the diameter of the sealing edge then being greater than that of the casing on which it engages and the adjustment means being caused to constrict the sealing edge for assembly purposes. As shown, a metallic ring 10 is pressed into engagement with an annular ridge portion 30 of the casing so that the sealing edge is pressed on to the shaft 16 and the expanding means 12, which is in the form of a sleeve screw threaded into the body portion 23 of the sealing ring, serves not only for assembly purpose described above but to maintain engagement of the diaphragm with the ridge 30 and to adjust the tightness of the sealing edge 28 on the shaft. A metallic 0-ring 42, which is deformed by the nut 14 acting through spacer rings 40, serves to prevent leakage of fluid between the casing and the sealing ring 10.
