Title: New or improved process for bringing mutually immiscible liquids of different specific gravity into intimate contact
IPC: B01D11/04
Filed: 1932-06-30
Abstract: <PICT:0404005/III/1> <PICT:0404005/III/2> In the washing of oils or benzol or other motor fuels the oil and washing liquid e.g. sulphuric acid or alkaline solution, are passed in contact through an elongated confined space where they are divided into discrete portions and subjected to agitation or pulsation such as to cause the transfer of liquid from one portion to another.  Suitable apparatus comprises a treatment vessel 1 fitted with vertical baffles which extend alternately from the top and bottom and thus divide liquid into portions.  The vessel is provided with inlets 2, 4, and outlets 3, 5 for the lighter and heavier liquids respectively.  Pulsations communicated through a pipe 9 from a plunger reciprocating in a cylinder cause agitation of the several portions of liquid and the transfer of liquid from one portion to the adjacent portion, effecting a countercurrent flow.  Liquid may pass to the inlet 2 through a bubbler tower 6 and sight glass 7 and may be discharged from the outlet 3 through a settling vessel 8.  The vessel 1 may be built up of pipe sections each of which is formed with one baffle. Modified constructions of the vessel 1 are described, in one of which the vessel takes the form of an undulatory tube and in another that of a helical tube.  Fig. 12 shows an alternative arrangement for the supply of liquid from the tower 6 to the inlet 2.  The liquid enters an open vessel 21 having an overflow 22 through a pipe 20 and passes to the inlet 2 through U-tubes 23 connected to the pulsator by a pipe 24.  The U-tubes may be replaced by a siphon.

[Class 100 (iii)] Keyboards.-The usual keyboard, having as many keys as there are channels in a magazine, is replaced by one having the standard or universal lay-out employed in typewriters and like machines. The matrix fount is divided into two groups, and the keyboard of forty-six keys, which is normally connected to the matrix-releasing devices of one group, can be connected to those of the other by means of a shift-key. A second shift-key enables certain of the keys to be connected to the releasing- devices of the smallcapital characters. The escapement-reeds B, Fig. 2, are, as heretofore, operated by cam-yokes C and power-rolls D from key - controlled slides E. The keyboard comprises twenty-six alphabet keys F<1>, Fig. 3, and twenty non-alphabet keys, F<2>, the latter being devoted to numerals, ligatures, punctuation marks, &c. The keyboard is pivotally mounted in the machine frame, as described in Specification 318,072, [Class 100 (iii)], and can be exchanged. The keys are formed with depending projections, which, when the keys are depressed, encounter banking - bars I supported on spring plungers I<3>, so as to give a " typewriter touch " to the keys. The banking-bars may be swung upwards, in order to lock the keys. The key-levers engage at their rear ends beneath actuating-levers J, which lift bails J<1> arranged in four superposed sets, each bail being operated by one lever. The bails lift levers J<3>, Figs. 4 and 6, which, in turn, lift vertical actuating-rods K. These act through levers L to lift the matrix-releasing slides E. The levers L are mounted in a rocking shift-frame P, operated by two shiftkeys, and have at their forward ends teeth and notches, differently located and co-operating with ears k<1> on the rods K. The teeth and notches are so arranged that, in the case of the alphabet keys, different levers L are operated by each key in the three positions of the shift-frame, so as to operate the escapement - reeds of uppercase, lower - case, and small-capital matrices respectively. Most of the non-alphabet keys bear two characters, the lower set of characters consisting mainly of numerals, and the other comprising signs and ligatures. In the normal, or lower - case, position of the shaftframe, these keys are connected to slides E which release matrices bearing numerals. In the upper-case position of the shift-frame, matrices bearing the signs &c. represented in the upper row of key-characters are released. The small capitals are carried on matrices bearing two unlike characters, the second characters being numerals or signs. The characters required are positioned by means of the duplex rail, as usual. The shift-keys are provided with lock-keys, by means of which they can be latched down when desired.

In a gas-turbine engine in which fluid is passed through a turbine blade to cool it or through a compressor blade or inlet guide blade for heating or de-icing purposes, the blade has at least two longitudinally arranged passages, one situated further from the blade edge than the other and forming a fluid inlet passage, the other passage forming a fluid discharge passage, the inlet and discharge of fluid taking place through ports situated on opposite sides of the blade stem, and the passages are interconnected by a narrow slot or series of small transverse passages for the transfer of fluid in the form of a high velocity jet or jets directed towards the blade edge. In the gas turbine blade shown, air or other cooling fluid enters a central longitudinal passage 11b through a port 17 at one side of the blade stem and is discharged through narrow passages 19b, 21 in the form of highvelocity jets directed on to the internal walls adjacent the leading and trailing edges of the blade. The passages 19b, 21 may be of circular, square or rectangular cross-section and, as shown, may be groupd adjacent the longitudinal central portion of the blade where cooling is most needed. Alternatively, each set of passages 19b or 21 may be replaced by a single, narrow longitudinally-extending slot. After passing through longitudinal passages 12b, 13b, the cooling fluid is discharged partly through the open outer ends of the passages 12b, 13b and partly through ports 16, 18 at their inner ends. The ports 16, 18 are located at the side of the blade stem opposite to that containing the port 17. The passages 21 and a plug 20 closing the outer end of passage 11b may be omitted, fluid then passing from the outer end of passage 11b to the outer end of passage 13b (both outer ends being closed by plate 14) and then passing inwardly through passage 13b to cool the trailing edge of the blade. The outer end of passage 12b may be closed by a plug.
