Title: Improvements in or relating to the damping of pulsations in fluids
IPC: F16L55/027
Filed: 1949-11-17
Abstract: 683,401. Regulating fluid flow. BRITISH OXYGEN CO., Ltd., and WATTS, S. S. Nov. 15, 1950 [Nov. 17, 1949], No. 29426/49. Class 135. A method of damping pulsations in a stream of fluid flowing in a pipe line consists in dividing the stream into a number of tributaries each constrained to follow a path diverging symmetrically from the direction of flow of the main stream such that the fluid forming each tributary expands continuously during its passage along the path and subsequently reuniting the tributaries to flow in the direction of the main stream, the dimensions of the individual tributaries being such that the pulsations therein are displaced relative to one another and so tend to cancel one another when the tributaries are reunited. The apparatus for carrying out the above method comprises a chamber 1 of greater diameter than the pipe line 2 in which it is inserted. The flow from the inlet 3 is divided by a number of baffle plates 5 mounted on bolts 6 and separated by spacers 11. All the plates except the plate 10 furthest from the inlet are apertured and the apertures decrease in size away from the inlet. The spacers 11 may be formed as radial fins to prevent swirl. Where swirl is desirable the spacers 11 are of spiral form. The annular space 8 between the wall of the chamber 1 and the plates increases progressively from the inlet. This is done by progressively decreasing the diameter of the plates as shown, or by using plates all of the same diameter and making the wall of the chamber 1 of conical shape. Pulsations in the reunited stream are further reduced by an assembly of baffle plates 12 similar to the plates 5 in front of the outlet 4.

Title: Improvements in or relating to drying devices for separated coarse material in ball or tube mills
IPC: B02C23/00
Filed: 1932-10-21
Abstract: 395,912. Ball or tube mills ; drying. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Krupp Grusonwerk Akt.-Ges., F. ; Buckau, Magdeburg, Germany.) Oct. 21, 1932, No. 29489. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 22, 1932.] [Class 59.] In a ball mill in which an air current passing through the mill carries the ground material to a sifter where the coarse material is separated out and is conducted back to the mill drum, the coarse material is dried previous to its re-introduction to the drum. The coarse material may be dried either in the sifter or in the return pipe to the drum. As shown in Fig. 1, the material to be ground is fed into the drum 21 through a pipe 2, through which the air current enters, and the ground material is carried by the air current up a pipe 22 to a sifter 23, the air then passing through a dust extractor 24 and back to the mill through fan 38 and pipe 40. Material separated in the sifter 23 passes through a pipe 26 to a drying column 27 comprising staggered ledges 28 from which the material is deflected as it falls downwardly into the pipe 40 through which it is carried by the air blast into the mill. Hot air is admitted to the dryer through a pipe 29 and ascends through the falling separated material and leaves either through a pipe 32 or is led through a pipe 33 into the dust extractor 24. An alternative feeding device 36 discharges fresh material into a byepass pipe 37 through which a current of air from the fan 38 passes and the fine material is carried thereby into the sifter 23. The coarse material passes through a pipe 39 into the pipe 40 and is carried into the mill through an extension 401. In a modification, Fig. 2, hot air from a pipe 41 is branched at 42 to the inlet of the mill, the return air from the fan 52 surrounding this pipe and conveying the ground material to a sifter 46 from which the coarse material returns to the mill through a pipe 47 and the fines are conveyed to a cyclone 49. Branch pipes 55, 56, 57 from the pipe 41 supply hot air to various parts of the circuit. The mill, separator and cyclone may be jacketed to receive hot air separately or in succession or the hot air may pass through the jackets and then into the mill circuit.
