Abstract
An indexable cartridge and method that is useable in either a stagnant fluid environment or in a moving fluid environment with the indexable cartridge floatable in a stagnant fluid environment and securable in a moving fluid environment with the indexable cartridge having a housing having one or more diffusion ports and a sleeve having one or more diffusion ports indexable to a diffusion port alignment through resilient yielding of the sleeve while a set of ribs inhibit lateral flow therebetween.
Claims20
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 a one or more diffusion ports therein to permit transfer of a dispensing material from said chamber;
- 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.
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.
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.
