Patent number: 9447703Abstract: The present invention provides a method and apparatus of processing material having an organic content. The method comprises heating a batch of the material (“E”) in a batch processing apparatus (16) having a reduced oxygen atmosphere to gasify at least some of the organic content to produce syngas, The temperature of the syngas is then elevated and maintained at the elevated temperature in a thermal treatment: apparatus (18) for a residence time sufficient to thermally break down any long chain hydrocarbons or volatile organic compounds therein. The calorific value of the syngas produced is monitored by sensors (26) and, when the calorific value of the syngas is below a predefined threshold, the syngas having a low calorific value is diverted to a burner of a boiler (22) to produce steam to drive a steam turbine (36) to produce electricity (“H”).Type: GrantFiled: April 30, 2013Date of Patent: September 20, 2016Assignee: Chinook End-Stage Recycling LimitedInventors: Rifat Al Chalabi, Ophneil Henry Perry, Ke Li

Patent number: 9447704Abstract: A heat recovery system for an internal combustion engine may include a heat transfer device flowed through by a fluidic heat carrier for transferring the heat from a combustion exhaust gas of the internal combustion engine to the heat carrier, a heat power machine flowed through by the heat carrier for converting the heat transferred to the heat carrier into mechanical work, a substantially cyclically closed duct system for connecting the heat transfer device with the heat power machine, at least one displacement pump for conveying the heat carrier through the duct system in a predetermined flow direction, and a pump drive for driving the displacement pump. A reduced wear may result when the heat recovery system is supplemented by an impermeable separating membrane for the fluid-tight separation of the heat carrier from the pump drive.Type: GrantFiled: July 10, 2014Date of Patent: September 20, 2016Assignee: Mahle International GmbHInventors: Jochen Eggler, Alfred Elsaesser, Christian Maisch, Sascha Senjic

Patent number: 9447705Abstract: In a fossil fuel waste incineration or plasma gasification process, waste heat generated by combustion of waste is captured by a heat transfer fluid and conveyed to an Organic Rankine Cycle (ORC) for energy recovery. In the case of a fossil fuel-fired waste incineration system, the heat transfer fluid captures waste heat from a double-walled combustion chamber, a heat exchanger being used to cool the hot process exhaust (gas cooler). In the case of a plasma waste gasification system, the heat transfer fluid captures waste heat from a plasma torch, a gasification chamber and combustion chamber cooling jackets as well as any other high-temperature components requiring cooling, and then a heat exchanger used to cool the hot process exhaust (gas cooler). The heat exchanger may take on several configurations, including plate or shell and tube configurations.Type: GrantFiled: March 14, 2012Date of Patent: September 20, 2016Assignee: PYROGENESIS CANADA INC.Inventors: Jason Robert Tavares, Pierre Carabin

Patent number: 9447706Abstract: A bearing frame or cylinder head cover of an internal combustion engine may include at least one camshaft mounted therein. The camshaft may be tunnel-mounted in at least two bearing openings arranged along a bearing channel. At least two radial bearings may be arranged on the camshaft, each of the radial bearings having an outer bearing shell. The outer bearing shells of the at least two radial bearings may include different outer diameters, each of the respective outer diameters adapted to be complementary to an inner diameter of the associated bearing opening. The inner diameters of the bearing openings may decrease in a direction of assembly of the camshaft along the bearing channel.Type: GrantFiled: April 24, 2014Date of Patent: September 20, 2016Assignee: Mahle International GmbHInventors: Frank Dautel, Thomas Flender, Klaus Heidenberger, Antonio Menonna, Kurt Schwellenbach, Stefan Steichele

Patent number: 9447708Abstract: An electro-hydraulic valve train is configured to change valve lift and valve opening/closing timing according to operation state of an engine. The electro-hydraulic valve train includes a valve stem having a valve head formed at a lower end thereof and a big-diameter stem formed at a middle portion thereof, the big-diameter stem having a larger diameter than the other portion, a swing arm having a roller contacting with a cam of a camshaft and an end connected to the valve stem, the one end being adapted to pivot with respect to the other end according to a rotation of the cam so as to move the valve stem upwardly or downwardly, a first brake unit enclosing the valve stem and adapted to perform brake operation in a case that the valve stem moves upwardly, and a second brake unit mounted at the other end of the swing arm and adapted to selectively move the other end of the swing arm upwardly or downwardly and to perform brake operation in a case that the other end of the swing arm moves downwardly.Type: GrantFiled: April 17, 2014Date of Patent: September 20, 2016Assignees: Hyundai Motor Company, Kia Motors CorporationInventor: Myungsik Choi

Patent number: 9447711Abstract: Forming of a valve head portion (1) of a hollow engine valve (V) comprising a material particularly satisfactory in heat resistance is performed by cold forging. The material with excellent heat resistance is worked to form a valve head portion semifinished product (11) having a hollow hole (S11) whose inner diameter (?11) is equal to the maximum inner diameter (?11) of a hollow hole (S1) of a finished product of the valve head portion (1), and having a diameter-increased section (111) whose maximum outer diameter (?12) is equal to the maximum outer diameter (?12) of a diameter-increased section (1a) of the finished product. Parts of the valve head portion semifinished product other than a central part to a lower part of the diameter-increased section (111) are necked down by cold forging performed a plurality of times to obtain the finished product of the valve head portion (1).Type: GrantFiled: July 31, 2013Date of Patent: September 20, 2016Assignees: FUJI HOLLOW VALVE INC., YOSHIMURA COMPANYInventor: Hyoji Yoshimura
