a sleeve having a one or more diffusion ports therein including an axially resiliently yieldable region having an upper axially resilient band located above a circumferential slot in the sleeve and a first lower axially resilient band and a second lower axially resilient band located below the circumferential slot in the sleeve, said axially resilient yieldable region extending partially around a circumference of said sleeve to normally inhibit rotation of said index tab with said housing but resiliently yieldable in response to an external torque between said housing and said sleeve, said circumferential slot having a plurality of notches for engaging the extension of the index tab to maintain the housing and the sleeve in a linked condition; and a first sealing rib located proximate one side of said one or more diffusion ports of said sleeve and a second sealing rib located proximate an other side of said one or more of said diffusion ports of said sleeve, said first sealing rib and said second sealing rib forming a fluid seal between said sleeve and said housing to inhibit lateral fluid transfer therepast and to encourage fluid transfer through a transport area defined by an alignment of the one or more of the diffusion ports in said housing and the one or more of the diffusion ports in said sleeve. ### Claim 2 (depends on 1) The indexable universal cartridge of claim 1 wherein the sleeve is indexable with respect to said housing. ### Claim 3 (depends on 1) The indexable universal cartridge of claim 1 including an index tab for rotationally locking said housing to said sleeve. ### Claim 4 (depends on 3) The indexable universal cartridge of claim 3 wherein the index tab is located on said housing and the sleeve includes an axially resiliently yieldable band to normally inhibit rotating of said index tab with respect to said housing but resiliently yieldable in response to an external torque between said housing and said sleeve to permit rotation of said housing with respect to said sleeve to thereby bring more or less of the one or more diffusion ports of the housing into alignment with the one or more of the diffusion ports of the sleeve. ### Claim 5 (depends on 1) The indexable universal cartridge of claim 1 wherein the sleeve contains an axial row of one or more diffusion ports and the housing contains a plurality of transaxial rows of the one or more diffusion ports with said first sealing rib and said second sealing rib located substantially parallel to each other and having widths less than a lateral spacing between the one or more diffusion ports in each of the plurality of transaxial rows of the one or more diffusion ports to thereby inhibit lateral transfer of fluid between the housing and the sleeve. ### Claim 6 (depends on 1) The indexable universal cartridge of claim 1 wherein the one or more diffusion ports in said housing are located along a surface element in said housing. ### Claim 7 (depends on 1) The indexable universal cartridge of claim 1 wherein the one or more diffusion ports in said housing comprises a first and second set of one or more diffusion ports located diametrically opposite from each other. ### Claim 8 (depends on 1) The indexable universal cartridge of claim 1 including a float to maintain at least part of the universal cartridge in a submerged condition and part of the universal cartridge in an unsubmerged condition. ### Claim 9 (depends on 1) The indexable universal cartridge of claim 1 wherein the housing includes a protruding index tab with an extension and the sleeve includes a circumferential slot with a plurality of notches for engaging the index tab to lock the housing to the sleeve and an upper sidewall and a lower sidewall of the circumferential slot acting to normally prevent an axial or rotational displacement of the housing with respect to the sleeve. ### Claim 10 (depends on 1) The indexable universal cartridge of claim 1 wherein the housing and the sleeve are comprised of a polymer plastic. ### Claim 11 (depends on 1) The universal indexable cartridge of claim 1 wherein the one or more diffusion ports in the sleeve extend in an axial direction and the one or more diffusion ports in the housing extend in both an axial direction and a circumferential direction. ### Claim 12 (depends on 1) The indexable universal cartridge of claim 1 wherein the housing comprises a frusto conical shape and the sleeve comprises a frusto conical shape so that a full frictional engagement between said first sealing rib and said second sealing rib extending therebetween does not occur until the sleeve and housing are in an axially fixed position with respect to each other. ### Claim 13 (depends on 1) The indexable universal cartridge of claim 1 wherein the sleeve contains a viewing window and the housing includes one or more reference settings with at least one of the referencing settings visible through the viewing window so as to provide a visible diffusion setting of the universal cartridge when the housing and sleeve are in an assembled condition. ### Claim 14 An indexable universal cartridge for controllable delivery of a dispersant in either an open or a closed fluid system comprising: a housing having a chamber therein for carrying a dispensing material, said housing having one or more diffusion ports therein to permit diffusion of a dispensing material from said chamber; a sleeve having one or more diffusion port; an axially resilient yieldable region having an upper axially resilient band located above an indexing slot in the sleeve and a first lower axially resilient band and a second lower axially resilient band located below the indexing slot in the sleeve, said axially resilient yieldable region extending partially around a circumference of the sleeve; and an index tab, on said housing and in engagement with a notch located between the upper axially resilient band and the first lower axially resilient band to maintain said housing in an indexed condition with respect to said sleeve while acting with said sleeve and said housing to provide a visual indication on alignment of the one or more of the diffusion ports of the sleeve with the one or more diffusion ports of the housing to thereby provide an operator with a visual indication of a size of a fluid transfer area between the chamber in the housing and the exterior of the sleeve. ### Claim 15 (depends on 14) The indexable universal cartridge of claim 14 wherein the housing and the sleeve are maintained in a rotational engagement with each other through an index tab protruding from said housing and a sidewall of a partial circumferential slot in said sleeve. ### Claim 16 The method of indexing a dispenser to change a first diffusion rate to a second diffusion rate comprising: placing a dispensable material into a housing having a one or more diffusion ports with the housing normally linked to a sleeve having one or more diffusion ports; torqueing the sleeve with respect to the housing with sufficient torque so as to cause a portion of the sleeve to resiliently yield to allow an indexing rotation of the sleeve with respect to the housing to thereby change an alignment of the one or more diffusion ports of the housing with the one or more diffusion ports of the sleeve. ### Claim 17 (depends on 16) The method of indexing the dispenser of claim 16 including the step of using a pair of ribs to inhibit lateral flow between the housing and the sleeve. ### Claim 18 (depends on 16) The method of indexing the dispenser of claim 16 including the step of engaging a pair of ribs on the sleeve with the housing. ### Claim 19 (depends on 16) The method of indexing the dispenser of claim 16 wherein the yield of the sleeve comprises an axial deflection ### Claim 20 (depends on 16) The method of indexing the dispenser of claim 16 comprising forcing an index tab from a first notch on the sleeve into a different notch in the sleeve without deforming the index tab.
