| 20120272626 | EXHAUST GAS TREATMENT DEVICE FOR AN OXYGEN COMBUSTION SYSTEM - In an exhaust gas treatment device provided with: an exhaust gas treatment unit in which an oxygen combustion boiler | 11-01-2012 |
| 20130091810 | MOTOR, FAN AND CYCLONIC SEPARATION APPARATUS ARRANGEMENT - A motor, fan and cyclonic separation apparatus arrangement for a vacuum cleaner, the arrangement comprising: a motor coupled to a fan for generating air flow; a cyclonic separation apparatus located in a path of the air flow generated by the fan; and a pre-fan filter located in the path of the air flow downstream of the cyclonic separation apparatus and upstream of the fan, wherein the cyclonic separation apparatus comprises at least one cyclone comprising: a cyclone body with a longitudinal axis; an air inlet port arranged tangentially through a side of the cyclone body; and an air outlet port through a longitudinal end of the cyclone body, wherein the pre-fan filter is arranged upon the air outlet port of the or each cyclone. | 04-18-2013 |
| 20100005763 | AERODYNAMIC SEPARATION NOZZLE - Multiple designs and methods for aerodynamic separation nozzles and systems for integrating multiple aerodynamic separation nozzles into a single system are disclosed herein. These aerodynamic separation nozzles utilize a combination of aerodynamic forces and separation nozzle structure to induce large centrifugal forces on the gases that in combination with the structure of the nozzle are used to separate heavier constituents of the process gas from lighter constituents. In some embodiments a number of separation nozzles are combined into a single system suitable for dynamic processing of a process gas. In other embodiments the separation nozzles are temperature controlled to condition the incoming gas to a temperature in order to encourage a phase change in certain constituents of the gas to occur within the nozzle to further enhance separation. | 01-14-2010 |
| 20130145734 | DRAIN VALVE APPARATUS AND AIR SEPARATOR THEREOF - The drain valve apparatus and an air separator are provided. The air separator includes a main body having an upper cover and a cooling shaft extended the upper cover, an oil filter coupled to the cooling shaft, an outer body coupled to the upper cover and surrounding the main body and the oil filter, a drain body disposed at the outer body and having an interior passage, a drain valve passage, an air inflow passage and an exterior passage, and a drain valve. The drain valve apparatus includes a piston that has a first body, a second body, a connecting member, and a blocking body, and an elastic member that is connected to the first body and moves along a length direction of the drain valve passage. | 06-13-2013 |
