  • Patent number: 11872511
    Abstract: An apparatus and method are provided for a flangeless air filter configured to be mounted onto a flat surface within an air intake system of an internal combustion engine. The flangeless air filter is comprised of a cone-shaped filter medium, retained between a base and a cap, that is fabricated to remove contaminants and particulate matter from an intake airstream. The base includes a pliable seal that forms an airtight connection between the flangeless air filter and the flat surface of the air intake system. A mounting bracket and fasteners may be used to attach the base to the flat surface, compressing the seal there between. In some embodiments, the mounting bracket may be incorporated into, and made a part of the base. A cap is disposed on a top of the flangeless air filter and configured to direct the intake airstream around the cap and toward the filter medium.

The trunk comprises a channel, an air inlet end and an air outlet end disposed at two ends of the channel, and a dust filter hole communicating with the channel. The first and second retaining walls are respectively disposed correspondingly to the dust filter hole. When a dust-containing airflow to-be-filtered enters the channel from the air inlet end, the dust-containing airflow forms a centrifugal airflow that contains the dust and is thrown out of the channel at a position of the dust filter hole. The first and second retaining walls are respectively disposed on a traveling path of the centrifugal airflow, so that the centrifugal airflow sequentially strikes the first and second retaining walls to change the traveling direction and then discharges dust free clean air.

    Abstract: A side-covered axial flow filter has a housing, a filter core, a filter frame, and a side cover. When assembling, the filter frame and the filter core are both obliquely installed into the housing. Limiting ribs of the filter frame are obliquely mounted between first pushing panels and a clamping surface of the housing, and inner pushing parts of the limiting ribs abut the first pushing panels. The portions of the inner pushing parts abutting the first pushing panels serve as fulcrums to straighten the filter core and the filter frame, so outer pushing parts of the limiting ribs may abut the clamping surfaces of the housing and generate a strong torque and a tightly sealing effect without much effort. The side cover also abuts the filter frame when assembled on the housing, so the filter frame is under balanced pressure to avoid leak.

  • Patent number: 10436090
    Abstract: A soot separator utilizing a toroid portion to centrifugally separate soot particles from the exhaust gas of an internal combustion engine. Upon lesser or no flow of exhaust gas, gravity causes the retained particles to fall within the bottom of the separator. The soot separator further includes a baffle to deflect particles and further enhance soot removal. A method utilizing this soot separator and association with an internal combustion engine are also described herein.

  • Patent number: 10342647
    Abstract: An apparatus and method for removing amalgam and waste particles from dental office suction effluent. The apparatus includes an upper chamber and a solids collection canister removably secured thereto. Dental office suction effluent drawn through a dental suction wand enters the upper chamber along a lateral flow path above a substantially cylindrical internal wall portion. A gas component of dental office suction effluent changes direction by more than 60° before it exits the upper chamber through an exit port. A riser conveys a liquid and solids component of dental office suction effluent through a drain into the solids collection canister. A flow restrictor allows liquids and gases to exit the solids collection canister interior volume but prohibits solids from exiting the solids collection canister interior volume.

  • Patent number: 10222363
    Abstract: A measurement device includes: a capturing part for causing a liquid to capture detection target particles contained in a gas and causing a fluorescent substance specifically bondable to the detection target particles to be bonded to the detection target particles; a droplet forming part for forming aerosol-like droplets from the liquid; and a measurement part for irradiating light onto the droplets and measuring the fluorescence intensity of the droplets. The capturing part includes a cyclone which swirls the gas introduced from a gas introduction part in a circumferential direction, separates the detection target particles toward a wall surface of the cyclone body under a centrifugal force, introduces the liquid from the liquid introduction part, causes the liquid to capture the detection target particles separated toward the wall surface and continuously supplies the liquid to the droplet forming part.

  • Patent number: 10202889
    Abstract: A degas bottle for inducing a cyclonic direction of flow to incoming coolant is disclosed. The degas bottle includes a body and an air separator having a cylindrical wall. An incoming coolant inlet is attached to the upper end of the air separator and is positioned at a tangent with respect to the cylindrical wall of the air separator, thus inducing cyclonic action as the coolant enters the air separator. The air separator may be of a cylindrical shape or of a conical shape. As air trapped coolant tangentially flows into the air separator, it will follow the cylindrical or conical shape of the air separator. The centrifugal force keeps the incoming coolant pressed against the inner wall of the air separator coolant on the wall while air separates from the coolant. The cyclonically flowing coolant circles downward to the reservoir while air remains on top of the coolant.
