Patent number: 10737206Abstract: A filter and its holder each have a keyed surface, one being a protruding “key” and one being a recessed “lock,” wherein cooperation of these keyed surfaces is required in order for the filter to be installed in the holder. Modification/adaptation of the keyed surfaces, by changing the location, number and length of the key protrusions and cooperating recesses during manufacture, allows various sets of mating filters and holders to be produced so that only mating/matching filters and holders may be connected together. The keyed protrusions are preferably located on an upper shoulder or on protruding flange(s) of the upper end of the filter. The cooperating recess structure inside the filter holder comprises axial recesses that allow axial insertion of the key protrusions, and hence the filter, into the holder and also a circumferential recesses portion that receives multiple key protrusions to retain the filter in the holder.Type: GrantFiled: April 19, 2016Date of Patent: August 11, 2020Assignee: OMNIPURE FILTER COMPANY, INC.Inventor: Roger P.

Patent number: 9421485Abstract: Embodiments of a key system for filters and their connecting heads, brackets, or other holders are shown. The filter cartridge and its holder each have a keyed surface, one being a protruding “key” and one being a recessed “lock”. Cooperation of these keyed surfaces is required in order for the filter cartridge to be installed in the holder, so that mis-matched cartridges cannot be installed into the holder, for example, to prevent a particular type of cartridge from being placed in a filtration or other process where it would be inappropriate, or undesired. The keyed surfaces are selectively locate-able preferably at different circumferential locations on a perimeter of the filter and a corresponding location on a perimeter of the head/holder. The perimeter may be, for example, on an outer shoulder surface of a filter and an inner surface of a valve head, or on outer and inner surfaces of connectors that provide a liquid seal between the filter and the head/holder.Type: GrantFiled: October 22, 2013Date of Patent: August 23, 2016Assignee: OMNIPURE FILTER COMPANY, INCInventor: Roger P.

Publication number: 20110152074Abstract: Granules comprise binder-agglomerated active particles for liquid treatment or filtration. Each granule has a center core of a material that itself has binding properties without the addition of other binders or sprays or adhesives, or, alternatively, each granule comprises a matrix of active materials stuck together with the binder. The binder structure preferably ranges from a non-uniform matrix of binder formed by heat-deformed binder particles, to a clump of binder particles generally retaining the original shape or the binder particles, to non-continuous connectors of binder between active particles. The invented two-part media has high surface area per volume of media, which, because the outer surface and inner void surfaces of the particles are preferably substantially covered with active particles, translates to high activity for the preferred treatment process.Type: ApplicationFiled: June 22, 2010Publication date: June 23, 2011Applicant: OMNIPURE FILTER COMPANY, INC.Inventors: Roger P.

Publication number: 20110073551Abstract: Filter modules for use in a water dispenser, carafe, or other gravity-flow water filtration and dispensing unit are self-supporting, rigid and porous, and are adapted in size and shape to substantially fill a generally-cylindrical housing. The filter modules are molded forms of high-porosity compositions, so that they are consistent in performance and “non-dusting” compared to the unpredictable arrangements, positions, and performance of loose activated carbon particles. Filter modules may include activated carbon, zeolitic, resins, metal-scavengers, and/or other water filtration/treatment media granules/powders, for example, bound into a solid profile form by thermoplastic and/or other polymeric binders. Low melt index, or very low melt index, binders are preferred to maximize exposure of the activated carbon surface area.Type: ApplicationFiled: March 26, 2010Publication date: March 31, 2011Applicant: OMNIPURE FILTER COMPANY, INC.Inventors: ROGER P.

Publication number: 20080223797Abstract: Multi-core solid profile filter media blocks include multiple sub-blocks, which may be formed by providing a block with multiple interior cavities extending deep into the block, to allow water to flow deep inside the filter block to access the media of the sub-block (in the case wherein the cavities are at the inlet to the block) or that allows water to be collected from each filtration sub-block (in the case wherein the cavities are at the outlet from the block). One or more indentations/spaces/gaps in the exterior surface of the block also may be provided to separate and extend between portions of the sub-blocks, so that substantially all of the filter media of a sub-block is accessible to fluid for filtration. This way, a filter block may include a large amount of media in a small cartridge or package volume, and the filter block may exhibit good flow distribution and low pressure drop.Type: ApplicationFiled: September 20, 2007Publication date: September 18, 2008Applicant: OMNIPURE FILTER COMPANY, INC.Inventors: ROGER P.
