Abstract: 277,726. Mourgeon, L. May 21, 1926. Multiple-way valves. - A distributing-cock for effecting the circulation of one or more fluid currents through solid material contained in a series of chambers arranged around the cock comprises a cylindrical or like plug closed at its ends and divided into compartments by internal longitudinal and horizontal partitions, and a surrounding shell carrying a number of superposed channels, the compartments and the channels co-operating with one another as described below. The invention is described with reference to the treatment of carbonaceous material first with a warm gas current for the purpose of heating them, then with a hotter current for the purpose of distilling off volatile constituents, and finally with a cooling current. When eight treating-chambers are arranged around the cock, the plug, as shown in developed form in Fig. 21, is divided into nine compartments by partitions 29, one of these compartments being entirely closed, and the shell, as shown in Fig. 2, carries superposed channels 1 - - 7 each having eight equidistant internal apertures 9 - - 15. The channel 1 is divided by partitions 16, Fig. 3, into eight sections each having an external aperture 20 leading to a treating- chamber, and the channel 7 is similarly divided into sections each having an external aperture 21, as shown in developed form in Fig. 19. The remaining channels 2 - - 6 are not divided, and each has a single external aperture 22 - - 26 respectively. In use, the first gas current is admitted at 24 into the channel 4, traverses the compartment 31, 32, Fig. 21, of the plug, passes thence through a section of the channel 7 and an aperture 21 to the first treating-chamber, traverses that chamber from bottom to top, returns to a section of the channel 1, passes through the compartment 33, 34 of the plug, and finally leaves the cock by the aperture 23. The second current is admitted at 26 into the channel 6, traverses the compartment 35, 36 of the plug, and passes thence to the second treating-chamber through a section of the channel 7. It returns to a section of the channel 1 and passes through the compartment 37, 38 of the plug and through another section of the channel 7 into the third treating-chamber. It returns again to the channel 1, passes through the compartment 39, 40 of the plug and through a further section of the channel 7 into the fourth chamber, and again returns to the channel i. Finally, it passes through the compartment 41, 42 of the plug and escapes through the channel 2 and aperture 22. The third current is admitted at 25 into the channel 5 and, passing through the compartment 43, 44 of the plug, reaches the fifth chamber by way of a section of the channel 7, returns to the channel 1, traverses in turn thet compartment 45, 46 of the plug, a section of the channel 7, and the sixth chamber, and again returns to the channel 1. Thence it passes into the plug through the aperture 47 and mixes with the second current, the heat abstracted in cooling the materials thus being utilized. The seventh and eighth chambers are connected to those sections of the channels 1, 7 which are in contact with the closed compartment of the plug, and may be emptied and re-charged without interrupting the treatment. By rotating the plug through 45‹ the order of the chambers is correspondingly altered, the fire becoming the second and so on, and this rotation is effected periodically., A modified construction of shell is described in which the channels 2 - - 6 are replaced by external pipes each connected to the shell by eight equidistant tubes; the channels 1, 7 also may be similarly modified.
