US 7,146,999 B2 56 Exemplary dimensions for the blocks 100 are 1 inch thickness between the block faces 102, block sides 104 Which are each 1.5 inches Wide, and a central bore 106 having an average diameter of 1 inch. Exemplary dimen sions for the channels 108 are 1/2 inch, 1A inch, and 1/s inch. However, different dimensions could be used, and it is also possible to use different blocks 100 having different dimen sions in the same ?uid handling device; for example, dif ferent blocks 100 might be formed With 1 inch, 2 inch, and 4 inch thicknesses for use together in the same ?uid handling device,Withthe2inchblocke?fectivelytakingtheplaceof 2 vertically stacked 1-inch blocks, the 4 inch block effec tively taking the place of 4 vertically stacked 1-inch blocks (or 2 vertically-stacked 2-inch blocks), etc. 120 and 122 could be countersunk so that any could serve as the insertion point for a fastener 124, and/or elongated fasteners, threaded rods, or smooth tie rods With threaded ends could be used to simultaneously vertically a?ix more than tWo blocks 100 together. The channels 108 preferably include countersunk depres sions 114 at the block sides 104 so that O-rings (not shoWn in the draWings) can be ?t to the ends of the channels 108 betWeenhorizontallyadjoiningblocks100,therebyenhanc ing leak-resistant sealing. The insert 110 in FIG. 1 is shoWn With a similar countersunk O-ring depression (as Well as O-ring 116), though such depressions could also or altema tively be formed on the channel ends intersecting the bores 106. Insimilarrespects,theclosureplates118preferablyhave a thickness Which is some integral divisor of the standard thickness of a block 100 (i.e., the closure plate thickness:1/ n*blockthickness,Whereinn:1,2,3,...).Whereauser vertically arrays blocks 100 and closure plates 118, this alloWsausertoreadilyrealignblocks100incommonplanes 20 bysimplystacking(andpreferablyattaching)extraclosure extendsfurthertoWardthetipsofthefurcationsononeside plates 118 until the blocks 100 situated atop the closure plates 118 rest in the desired plane. While each of the closure plates 118 is illustrated With three (countersunk) fastener openings122,theycouldbearadditionalfastenerholes(e.g.,25 atalcomers). The face fastener openings 120 and closure plate fastener openings 122 are preferably formed With identical diameters andthreading,e.g.,sothatbothcanaccept1(L32UNF SHC hexscreWs.Intheexemplaryblocks100shoWninthe30 draWings, three of the face fastener openings 120 are depicted as being countersunk, With three non-countersunk face fastener openings 120 interspersed therebetWeen. The countersunk face fastener openings 120 are used as the insertionpointforthefasteners124a?ixingvertically 35 adjoining blocks 100 so that the fasteners 124 Will not have protrudingheadsoncefullyinserted(see,forexample,block 10011 in FIG. 2). The non-countersunk face fastener open ings 120 are used to receive the ends of fasteners 124 extendingfromadjacentvertically-stackedblocks100,orto40 receive fasteners 124 extending from the closure plates 118 to the block faces 102. Preferably, each of the face fastener openings 120 is countersunk at one of the block faces 102, i.e., the non-countersunk fastener openings 120 in FIG. 1 are countersunkWheretheyemergeattheopposite(unshoWn) 45 faceoftheblock100,andthecountersunkfasteneropenings 120 in FIG. 1 are not countersunk Where they emerge at the opposite(unshoWn)faceoftheblock100.Thus,thetopand bottom faces 102 of the blocks 100 are effectively inter changeable.Notethattheinterspersingofthecountersunk 50 fastener openings 120 With the non-countersunk fastener openings 120 leads to the staggered fastener arrangement best seen in FIG. 2, Wherein the closure plate 118 has fasteners 124 inserted in its countersunk fastener openings 122toextendintonon-countersunkfasteneropenings120in55 block 100d; block 100d then has fasteners 124 inserted Within the countersunk fastener openings 120 to extend into the non-countersunk fastener openings 120 in block 1000 (With these fasteners 124 being staggered 60 degrees from thefasteners124extendingfromtheclosureplate118);and 60 block 1000 has fasteners 124 inserted Within the countersunk fastener openings 120 to extend into the mounting plate fastener openings 136 (With these fasteners 124 being stag gered 60 degrees from the fasteners 124 extending from the block1000).Ineffect,eachverticallystackedcomponent 65 has its fasteners 124 rotationally staggered With respect to theadjacentcomponent.Alternatively,alfasteneropenings of the side fastener 128 than on the other (note the appar ently different lengths of the furcations in FIG. 1), and thus this bridging member 130 e?fectively forms a concavity betWeenthesidefastener128andtheblock100Whenthe side fastener 128 is installed. This concavity can receive a screWdriver tip to further assist in removal of a side fastener 128. The inserts 110 depicted in the draWings are simple, With insert110inFIG.1,andinserts110aand11019inFIG.2, simply containing an insert passage 112 alloWing ?uid to horizontally traverse a block channel 108. Similarly, insert 1100 allows ?uid to pass from a channel 108 to a vertical Well Which further extends into insert 110d. HoWever, inserts 110canbecon?guredtodomorethansimplydirect?uid ?oW betWeen desired channels 108 and bores 106, and can contain sensors (e.g., thermocouples, ph sensors, conductiv ity sensors, pressure transducers, etc.), heating or cooling elements (preferably of the thermoelectric type), stirrers or pumpsfordriving?uid(orconverselyturbinesWhichcanbe driven by ?uid ?oW), valves, sources of laser or other light, spark or arc emitters, or virtually any other components useful in ?uid handling systems. It should be understood that an exemplary version of the inventionhasbeenshoWnanddescribedabovetoillustrate preferred features of the invention. Apart from rearranging these features and/or omitting or adding them in different forms and combinations, other modi?cations are also con sidered to be Within the scope of the invention. FolloWing is anexemplarylistofsuchmodi?cations. First, ifdesired, some or all channels 108 could be tapped With internal threading so that components such as threaded input/output ports, gas traps, probe/sensor mounts, etc. can be more easily installed. In similar respects, some or all closureplates118maybearcentrally-locatedportsWhich open onto the central bore 106 of a block 100 When installed on its block face 102, and Wherein such ports might ordi narily remain closed via a threaded plug or fastener. These ports could also or alternatively be used to accommodate sampling,measuring,orotherdevices. Second,?oW canbeblockedfromundesiredchannels108 by structures other than inserts 110 (for example, by inser tion of a plug, Which might be threaded to engage a complementarily threaded channel interior). Similarly, ratherthanusingclosureplates118,thecentralbores106 could instead be closed by the use of appropriately-shaped plugs or the like. As previously noted, the dogbone shape of the side fasteners 128 is useful to restrain adjoining blocks 100 together, and the furcated tips of the side fasteners 128 alloW the head of a screWdriver to be inserted to easily liftthe side fasteners128fromtheirsidefasteneropenings126.On each sidefastener128,themember130bridgingthefurcations
