A substrate for use in an aqueous slurry has a polymeric coating to provide a compliant and sticky surface. The polymer coating has a chemical to render the surface hydrophobic so as to attract hydrophobic or hydrophobized mineral particles in the slurry. The substrate can take the form of a conveyor belt, a bead, a mesh, an impeller, a filter or a flat surface. The substrate can also be an open-cell foam. The polymeric coating can be modified with tackifiers; plasticizers; crosslinking agents; chain transfer agents; chain extenders; adhesion promoters; aryl or alky copolymers; fluorinated copolymers and/or additives; hydrophobizing agents such as hexamethyldisilazane; inorganic particles such as silica, hydrophobic silica, and/or fumed hydrophobic silica; MQ resin; and/or other additives to control and modify the properties of the polymer.

Polymer-coated member having a reticulated foam substrate with an open-cell foam structure and at least one polymeric coated surface

A process of coating an open-cell foam substrate includes the steps of arranging two rollers separated by a gap; positioning the substrate above the gap; providing a coating material onto the substrate, feeding the substrate through the gap so as to achieve a layer of the coating material on the substrate, wherein the coating material is selected from the group consisting of a polysiloxane derivative, acrylic polymer, butyl rubber, natural rubber, nitriles, styrene block copolymers with ethylene, styrene block copolymers with propylene, styrene block copolymers with isoprene and polyvinyl ether and modifying the coating with tackifiers; plasticizers; crosslinking agents; chain transfer agents; chain extenders; adhesion promoters; aryl or alky copolymers; fluorinated copolymers; hexamethyldisilazane; and silica.

Processes for coating reticulated foams

A reactor system has a number of stations arranged to recover mineral particles in a slurry. The system includes a hopper to receive the slurry and barren media having hydrophobic coating to attract the mineral particles. The hopper provides a mixture of barren media and slurry to a tumbler arranged to stir the mixture in order to increase the contact between the slurry and the barren media so as to allow the mineral particles to attach to the barren media to form mineral laden media. The mineral laden media are conveyed to a rinsing station where water jets are used to wash the gangue materials off the mineral laden media. The rinsed mineral laden media are mixed with a surfactant so that the mineral particles are released from the mineral laden media. High-pressure water and air jets are then used to remove remaining surfactant from the released media.

A patient interface for communicating fluids to and/or from a patient's nasal cavity and/or oral cavity is disclosed. In addition, a patient interface for fluid and physiological function monitoring proximate to the patient's nasal cavity and/or oral cavity is disclosed. An apnea monitor and a method for monitoring apnea are also disclosed.

Nasal and oral patient interfaces

A filter assembly for use in sidestream gas sampling assembly. The filter assembly of the present invention includes a hydrophilic. The filter further includes a Hydrophobic member positioned downstream of the hydrophilic liner. The hydrophobic disk acts as a second line of defense against moisture reaching the sensing mechanism member that is constructed from a porous material and is situated such that gas entering the filter assembly passes through at least a portion the hydrophilic member. In a further embodiment, the filter includes a hydrophobic member positioned downstream of the hydrophilic member. The hydrophobic member acts as a second line of defense against moisture reaching the sensing mechanism in the gas sampling assembly.

Liquid absorbing filter assembly and system

Sidestream gas sampling assembly that does not substantially degrade the waveform of expired gases. The gas sampling assembly includes a sample cell portion integrated with a filter portion for separating undesired liquid condensate from respiratory gases to be monitored. The gas sampling assembly is configured to receive expired gases through a gas sampling line, filter undesired liquid condensate from the expired gases through hydrophobic fiber elements and communicate the filtered gases to a sample chamber which is in close proximity to the filter where measurements may be taken thereof e.g., optical or infrared sensing mechanisms. The gases that are substantially free of liquid condensate are then exhausted from the sample chamber.
