Patent number: 10390670Abstract: A separating apparatus including a first cyclonic separating unit that includes a first cyclonic separator having a separator axis, a second cyclonic separating unit that includes a second cyclonic separator, the second cyclonic separating unit being movable between a first position and a second position with respect to the first separating unit in a direction which is parallel with the separator axis, a screen disposed within the first cyclonic separator such that it extends parallel with the separator axis. The screen is connected to the second cyclonic separating unit for movement with the second cyclonic separating unit. The separating apparatus includes a wipe for cleaning the screen, wherein the wipe is secured to the first cyclonic separating unit such that movement of the second cyclonic separating unit from the first position to the second position moves the screen relative to the wipe thereby cleaning debris from the screen.Type: GrantFiled: January 19, 2017Date of Patent: August 27, 2019Assignee: Dyson Technology LimitedInventors: Kate Elizabeth Robinson, Stephen Robert Dimbylow, William Henry Kerr, Remco Douwinus Vuijk

Patent number: 10363565Abstract: The present invention discloses a portable cyclone dust separator, which comprises a first stage cyclone separation unit having an intake for suctioning air to be dedusted, the air suctioned through the intake rotating around a first rotational axis in the first stage cyclone separation unit; and a second stage cyclone separation unit having an air inlet, the air inlet being configured to be adapted to suction the air, which needs to be dedusted secondarily by the second stage cyclone separation unit, from the first stage cyclone separation unit, the air suctioned through the air inlet rotating around at least one second rotational axis in the second stage cyclone separation unit, wherein the first rotational axis is disposed to be nonparallel to the second rotational axis. The present invention also discloses a dedusting system comprising such a portable cyclone dust separator. The portable cyclone dust separator of the present invention is fit for the operating orientations within the greater angular range.Type: GrantFiled: January 2, 2017Date of Patent: July 30, 2019Assignee: BOSCH POWER TOOLS (CHINA) CO.

Patent number: 10342647Abstract: 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.Type: GrantFiled: August 17, 2016Date of Patent: July 9, 2019Assignee: Crosstex International, Inc.Inventors: Douglas S. Stolarik, Douglas M. Horner, Michael P. Mormino, Owen E. Boyd

Patent number: 10222363Abstract: 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.Type: GrantFiled: May 1, 2015Date of Patent: March 5, 2019Assignee: TOKYO ELECTRON LIMITEDInventor: Akitake Tamura

Patent number: 10202889Abstract: 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.Type: GrantFiled: January 20, 2015Date of Patent: February 12, 2019Assignee: Ford Global Technologies, LLCInventors: Yi Zhang, Eric Myers, Meisam Mehravaran, Cristian Gheordunescu
