Thus, heat in the generator that is mounted in an airtight engine compartment is dissipated.Type: GrantFiled: November 26, 2012Date of Patent: March 8, 2016Assignee: KWANG YANG MOTOR CO., LTD.Inventors: Chien-Ping Tseng, Wen-Ming Su

Patent number: 9279428Abstract: Devices, apparatus, systems, and methods for the quick installation of ceiling fan blades for ceiling fans. The invention uses a blade with three slots running in a linear direction from the mounting end of the blade, and three pre-attached fasteners upwardly projecting from the outer end of a blade arm. One of the fasteners is springably bendable with inwardly extending clip edge, another fastener that forms an upright post, and a third fastener having a top end with an outwardly extending lip edge. Another embodiment can include four slots per blade and four pre-attached upwardly protruding fasteners per blade arm. A novel method of installing each blade can include angling the blade to the mounting ends of the blade arm so that the outwardly extending lip edge catches on the third slot in from the mounting end of the blade.Type: GrantFiled: September 29, 2014Date of Patent: March 8, 2016Assignee: Chien Luen Industries Co., Ltd., Inc.Inventors: Tien S Lowe, Mark Veltuni

Patent number: 9279429Abstract: A blower housing has a discharge direction, an axis of rotation, a polar axis that intersects the axis of rotation and is substantially perpendicular to the discharge direction, and an angular sweep of increasing fluid flow area. The fluid flow area, A, increases with increasing angular magnitude, ?, as a function comprising at least a functional component that is at least one of (1) equal to, (2) substantially mathematically reducible to, and (3) substantially mathematically analogous to the equation, A ? ( ? ) = A co + R ? ( 1 - 1 - [ ( r i ) ? ( ? ) R ] 2 ) , where Aco is a minimum fluid flow area, R is a radius of a first circle, and ri is a radius of a second circle that is smaller than the first circle.Type: GrantFiled: May 18, 2015Date of Patent: March 8, 2016Assignee: Trane International Inc.Inventor: Stephen S. Hancock

Patent number: 9279431Abstract: A method for detecting rotating stall in a compressor is disclosed herein. The method comprises measuring radial vibration of the rotor relative to the stator and generating a vibration measurement signal, calculating a frequency spectrum of the vibration measurement signal, identifying a plurality of frequency bandwidths of the frequency spectrum, neglecting one first frequency bandwidth of the plurality of frequency bandwidths if the rotation frequency of the rotor falls within the first frequency bandwidth, neglecting at least one second frequency bandwidth of the plurality of frequency bandwidths if the rotation frequency of the rotor falls below the second frequency bandwidth, determining the maximum magnitude of the spectrum in each of the non-neglected frequency bandwidths, and comparing each determined maximum magnitude and a predetermined value.Type: GrantFiled: November 27, 2012Date of Patent: March 8, 2016Assignee: Nuovo Pignone S.P.A.Inventors: David Rossi, Daniele Galeotti

Patent number: 9279432Abstract: A media separating device (1), in particular a hydraulic accumulator (3), has a movable separator (5) separating two media (7, 9) received in media chambers (11, 13) and differing from each other. A measuring apparatus (15, 115) can detect an overflow of at least one medium (7, 9) from a medium chamber (11, 13) via the separator (5) into the other medium chamber (11, 13) having the other medium (9, 7).Type: GrantFiled: April 7, 2012Date of Patent: March 8, 2016Assignee: HYDAC TECHNOLOGY GMBHInventors: Matthias Leo Jirgal, Horst Mannebach, Martin Groben

Patent number: 9279433Abstract: A poppet valve assembly to control a pneumatic actuator may include a housing having a central bore. A first module may be disposed within the central bore, and the first module may have a first and second poppet valve. A second module may also be disposed within the central bore, and the second module may have a third and fourth poppet valve. A supply of pressurized fluid may be in fluid communication with a plurality of control valves such that pressurized fluid from the control valves opens and closes the poppet valves. The supply of pressurized fluid may also be in fluid communication with the first module and the second module such that the opening and closing of the poppet valves controls the position of the pneumatic actuator.Type: GrantFiled: March 30, 2012Date of Patent: March 8, 2016Assignee: General Equipment and Manufacturing Company, Inc.Inventor: Bruce R. Penning

Patent number: 9279434Abstract: The invention relates to a pressure medium system, in particular a hydraulic system, having a fluid pump for delivering a drive fluid with a certain delivery flow rate and a certain fluid pressure, and having a control unit which switches the fluid pump on or off in order to set a predefined setpoint value of the fluid pressure, wherein the fluid pump exhibits an inertia-induced overrun when switched off, such that during the overrun of the fluid pump, the fluid pressure still rises while the fluid pump has already been switched off. It is proposed that, during the increase of the fluid pressure to the predefined setpoint value, the control unit switches the fluid pump off before the fluid pressure has reached the predefined setpoint value. The invention also includes a corresponding operating method.Type: GrantFiled: June 20, 2012Date of Patent: March 8, 2016Assignee: Ludwig Ehrhardt GmbHInventors: Winfried Ehrhardt, Georg Westerhagen
