Abstract: 365,312. Centrifugal gas cleaners. INTERNATIONAL PRECIPITATION CO., 1016, West 9th Street, Los Angeles, U.S.A. Jan. 12, 1931, No. 1066. Convention date, Dec. 8, 1930. [Class 23.] Density separators.-A centrifugal apparatus for separating suspended material from gases consists of a number of separators 4 arranged in connection with inlet and outlet headers, while inclined vanes 14 are arranged in the annular inlet of each separator to give the entering gas a whirling motion. The diameter of each separator 4 is small compared with its height, and the outlet 12 for clean gas passes up through the inlet header 2 to the outlet header. The top 16 of the latter header is inclined as shown in Fig. 2. The separators are arranged in rows and the outlet header contains one chamber 3 for each row ; the chambers 3 unite at the outlet 18. While the main bodies of the separators are of circular cross section, their upper ends 8 are expanded to a square or rectangular cross section, so that when the units are assembled their sides are touching at the ends 8. To prevent any accumulation of deposited matter in the separators, each one is provided with a rod or chain 21 hanging from a support and extending through the separator. While the gas is flowing, the chain swings round and keeps the walls and discharge opening 19 clear. The gas is supplied to the inlet header 2 and passes downwards between the chambers 3 in the outlet header, to the annular inlets of the separators 4. In each separator the gas is cleaned and passes away by the outlets 12, the chambers 3 and the outlet 18. The separated dirt passes out by the openings 19 to the hopper 6. In the modification shown in Fig. 7, the inlet header has an inlet 26 and a hoppershaped extension 27. The outlet header 42 extends upwards from the square expanded ends of the clean gas outlets 39 and rises above the inlet header ; it is supplied with an outlet 43. The upper portions of the separators may be hexagonal in cross section.

Abstract: 687,034. Valve-actuating mechanism. NAAMLOOZE VENNOOTSCHAP KONINKLIJKE MAATSCHAPPIJ DE SCHELDE. Jan. 22, 1951 [Jan. 23, 1950], No. 1634/51. Class 135. Apparatus for remotely controlling a stop-valve disposed, e.g. in a ship's fuel tank or bilge, comprises a valve operating stem 5, Fig. 2, freely mounting a pinion 4 engageable with rack teeth 3, Fig. 1, formed on a piston 2 slidable in a double-acting cylinder 1, transversely disposed with respect to the stem. The pinion 4 is formed integral with a multistart thread 6 engageable with a fixed nut 7 for raising and lowering the stem. The piston 2 is formed with a slot 12 engageable with the upper end of a lever 13 which is mounted on a pivot pin 14 and operatively connected at its lower end to a spring 15 which through its housing 17 is connected to a fixed pivot pin 16. For direct manual operation a handwheel 18 and element 19 are fixedly mounted on the stem 5, the element 19 having a lost-motion lug and slot connection with the pinion 4. Under remote control, compressed air is admitted to one or other end of the cylinder 1, and, during the first half of the piston stroke the spring 15 is tensioned to store up energy which on the piston reaching its dead centre position is released to either assist the compressed air in completing the piston stroke or acting alone to do so. Under manual actuation, the handwheel 18 and the element 19 are rotated and take with them the pinion 4 which through the engagement of the teeth 3 moves the piston 2 during the first half of its stroke, the spring 15 taking over during the second half thereof. So that the operator does not experience the shock of the spring load the lost motion connection between the element 19 and the pinion 4 is arranged so that during the second half of the piston stroke the pinion 4 overruns the element 19, the element 19 being uninfluenced by the acceleration of the piston under the spring load.

Title: Method and apparatus for causing slags, which do not swell readily, to solidify in a highly porous condition
IPC: C04B5/06
Filed: 1937-01-22
Abstract: Slag is obtained in a porous or cellular condition by blowing gases through the slag whilst maintaining it at a temperature just above the melting point until it is saturated and subsequently agitating or otherwise treating it to release the absorbed gases. The frothing operation is facilitated by carrying out the blowing operation at a higher pressure than that which prevails during the subsequent frothing operation, which is preferably carried out under reduced pressure, and by heating the slag saturated with gases before the frothing operation to the degrees which it can bear without releasing dissolved gases, for example by the addition to it of slag direct from the furnace.  Gases which may be used for the blowing operation are hot air, blast furnace gases, nitrogen, carbon dioxide or carbon monoxide. Specifications 344,309 and 361,139 are referred to. According to the Specification as open to inspection under Sect. 91 the slag may be saturated with gases by exposing it in thin layers to the gases.  This subject-matter does not appear in the Specification as accepted.
