An oral irrigation device including a reservoir, a tip, and a pump. The pump is operative to draw fluid from the reservoir and propel the fluid to the tip. The pump includes a pump body fluidly connected to the reservoir and the tip, the pump body having an interior wall defining a pump chamber, the pump chamber terminating in an open end and a force exerting assembly that is receive within the pump chamber. The force exerting assembly is movable between a first position and a second position and includes a force exerting member and a compressible sealing member received around the force exerting member. The sealing member engages the interior wall of the pump body during movement from the first position to the second position and movement from the second position to the first position to prevent fluids from escaping the open end of the pump body.

A portable drinking water filter system, such as a pitcher, having a floatable body including a filter opening configured to receive a water filter, the floatable body having a seal extending outward from an outer surface of the floatable body. The floatable body is disposed in a container cavity such that a body seal engages the sidewall and restricts water from passing between the floatable body and the sidewall. The seal is configured to create friction with the sidewall, wherein the friction created when the floatable body rises in the container is different than when the floatable body lowers in the container. The friction created when the floatable body rises in the container is greater than when the floatable body lowers in the container, allowing the floatable body to auto-retract toward a cavity base without burping.


The present invention relates to water purification systems and uses thereof. In particular, the present invention relates to the use of water filtration systems to combat Legionella bacterial contamination of industrial and commercial water systems, such as grocery store misting systems.


There is provided a method for producing, at a high yield, a composition containing 3-chloro-4-methoxybenzylamine hydrochloride (CMBA-HCl) in which the purity of CMBA-HCl is high. This method comprises a chlorination step involving a chlorination reaction that generates CMBA-HCl from 4-methoxybenzylamine hydrochloride using hydrogen peroxide and hydrochloric acid. There is also provided a CMBA-HCl-containing composition which is produced by the aforementioned production method and in which the purity of CMBA-HCl is high.

Fluid filtration devices and methods of filtering fluids are described. The devices generally include a housing, a hollow filter assembly, a rotating cleaning assembly and a device to measure the accumulation of solids in the filter housing. In some embodiments the accumulation of solids is measured by measuring the torque required to rotate the cleaning assembly. Torque may be measured directly, such as with a torque sensor, or indirectly, such as by measuring the current used by an electric motor to drive rotation of the cleaning assembly. In some embodiments a purge valve is opened to remove accumulated solids from the housing when a certain level of solids accumulation is detected.


A vinylbenzylated phenol compound represented by General Formula (1) below is provided. (In General Formula (1), Ar^(0 )is a bifunctional phenol compound residue having one or more monocyclic or polycyclic aromatic nuclei, R^(1 )to R^(5 )may be the same or different and are each hydrogen or a methyl group, and p is an integer of 1 to 4.)

An intake screen assembly including an intake member, a screen support member, and a screen member coupled to the screen support member. The screen member may be formed from a material, such as copper-nickel, that is different from a material, such as stainless steel, used to form the intake member and/or the screen support member. The intake screen assembly may include corrosion protection members for preventing contact between the components of the screen assembly that are formed from dissimilar materials. The assembly may be formed by coupling the screen support member to the intake member, and coupling the screen member to the screen support member.

The present inventors have surprisingly discovered that phytic acid tenaciously precipitates with soluble metals in food or fuel ethanol-processing fluid, producing insoluble organometallic salt deposit or scale on the processing equipment that must be removed in order to facilitate further ethanol processing. The present invention relates to converting phytic acid salts or phytates to inorganic phosphates to improve metal solubility and reduce deposition within processing equipment.


Methods and systems for forming stable particles from suspended solids produced by ethanol fermentation are disclosed. The methods include providing a fraction from ethanol fermentation containing solids and suspended solids. The pH of the fraction is adjusted, if necessary. A reducing agent is added. A high molecular weight anionic polymer is added to form stable particles of solids and suspended solids. Lastly, the stable particles are free drained to separate them from a treated liquid portion. The treated liquid portion is added as backset to the fermentation process while the recovered solids are further processed into useful products.

Wood pulping process including pulping wood to produce a pulping effluent or liquor. Pre-concentrating the liquor in a pre-concentration unit produces concentrated liquor, a contaminated condensate and a non-contaminated condensate. Directing the concentrated liquor to a multi-effect train of forced circulation solids concentrators that further concentrating the concentrated liquor to form a highly concentrated liquor. Directing the contaminated condensate produced by the pre-concentration unit to a steam stripper and stripping gases therefrom and in the process producing a contaminated vapor stream. Utilizing the contaminated vapor stream and its thermal energy to power the forced circulation solids concentrators of the multi-effect train.
