Abstract: 1,271,117. Dispensing measured quantities of liquids. EASTMAN KODAK CO. 19 Sept., 1969 [20 Sept., 1968], No. 46210/69. Heading B8N. [Also in Division F1] A fluid logic switching circuit for first opening and then closing a liquid inlet control valve 28 located between a liquid source 26 and a metering tank 30 and for closing and then opening a liquid outlet valve 32 between the tank 30 and a consumer receptacle 34 comprises bistable means 14, 16 having first and second control output conduits 60, 62 which latter are connected by ducts 142, 144 to the respective valves 28, 32, means 138, 140 for producing a fluidic signal in the first control input 36 to produce an output in ducts 60, 142 when the inlet valve 28 is to be opened, and valve 32 is to be closed, analogue-digital means 18, 20, 22, 24 having first and second inputs 74, 76 and adapted to produce a signal in the second control input 38 of bi-stable means 14, 16 to switch the output of the latter to the second output duct 62, 144, thereby closing valve 28 and opening valve 32 in response to a predetermined back pressure in the second input 76 of means 18 and in turn responsive to a predetermined liquid level in tank 30. Prior to feeding a fill command signal to 138 and assuming gas supply pressure being available at 44, 58, 72, 88, 108 and 124 and bias pressure available at 86, 148, fluid flow in duct 80 results in flow in duct 96 which deflects the output of 22 into a vent 114 whilst the output of 24 is biased along vent duct 132 and output of 14 is biased along duct 40 to act as input to 16 thereby directing the output of 16 along 62, 144 to maintain valve 32 open. On generating the fill signal in input 36 of 14 the output of 14 is deflected to 42, the output of 16 is deflected to 60, 142, thereby opening valve 28 and allowing valve 32 to close by virtue of there being no signal in 62, 144. When the level in tank 30 rises sufficiently the back pressure is generated at 76 which thus deflects the output of 18 into duct 78 which in turn deflects the output of 20 into duct 94. The output of 22 is thus deflected into duct 116, the output of 24 is deflected into the input duct 38 of 14, the output of 14 is deflected into outlet 40 and the output of 16 is deflected into outlet 62 and duct 144 which pressure opens valve 32 to allow the known volume of liquid in 30 to pass to 34.

Further, the significance of the bit locations in the tag portion 22 of the store differs from word to word. In a simple case in which portion 22 is an n x n matrix, the bit position of significance k in the first word is progressively shifted for successive words to occupy positions on a diagonal of the matrix. Fig. 4 shows a more complex arrangement in which a 16 x 16 block is subdivided into 4 x 4 arrays, the rows within each array are end-around shifted with respect to the significance of the bit positions therein, and the arrays themselves are also end around shifted within each row of arrays. There may be a number of such blocks 25, 26 formed as integrated circuits in store portion 22. To perform an associative search on the stored data words, the search word is loaded in a register 40, the tag bits are used by addressing logic to generate appropriate diagonal enabling signals 43 so that any stored tag having the corresponding 1 out of n coded value will be read out as a signal on one of lines 29 to match identifying logic 46. The associated data part of the matching word may then be read from store portion 21. When there are a number of blocks 25, 26 in store portion 22 they may be searched in parallel (separate 29, 46) or consecutively (common 29, 46). The tag part of the matching data read out on lines 24 is de-skewed and recoded to binary at 51. Examples of recoding logic 30 which include a shift register, ROM's and adders are described.
