Publication number: 20170321721Abstract: A heat dissipating module including a casing, a fan, a plurality of blades and at least one locking element is provided. The casing has a first positioning side and a second positioning side opposite each other, and the casing includes a sliding recess located on the first positioning side. The fan is disposed in the casing. The blades respectively slide into the sliding recess and are positioned on the first positioning side and the second positioning side. The locking element passes through the sliding recess to limit the blades from moving out of the sliding recess.Type: ApplicationFiled: October 2, 2016Publication date: November 9, 2017Applicant: Wistron CorporationInventors: Xiao-Ju Huang, Zhao-Ping Fu

Publication number: 20170321724Abstract: A submersible pneumatic canister pump system for pumping liquid from a tank or underground location by incorporating a floating ball valve inside the pump for preventing air from exiting with the liquid discharge. The floating ball valve is located near the lower end of the pump and communicates with the discharge pipe. When liquid level approaches the lower end of the pump a ball of lighter density than the liquid rests on a seat and prevents further discharge of liquid and the passage of air out of the pump. Also shown are various pump control arrangements that can be used to operate the pump.Type: ApplicationFiled: May 3, 2016Publication date: November 9, 2017Inventor: Michael Kevin Breslin

Publication number: 20170321725Abstract: There is provided a pneumatic pump (10) comprising a tubular steel frame (11) and a disc-shaped pressure vessel (12) including a lower, tangential transfer port (14) and an upper, radial ventilation port (15). A transfer assembly (16) on the port (14) includes an inlet assembly (17) having a positive-close non-return valve (21) and a delivery outlet assembly (20). A venturi assembly (22) applies suction to the ventilation port (15) and has an exhaust vent (24) including a closure assembly (25) selectively operable to cycle between a suction phase and a pressurized phase. A two way T-valve (40) selectively allows venturi exhaust air to pass selectively into either a diffuser/muffler (35) or a delivery line (42) downstream of an outlet non-return valve.Type: ApplicationFiled: June 18, 2014Publication date: November 9, 2017Applicant: Bullseye Pumps Pty LtdInventor: Mark Damien Krohn

Publication number: 20170321726Abstract: Slip joint clamps seat on a diffuser end via external features of the diffuser, like guide ears, regardless of slip joint wear or damage. The clamps can be opened and closed to surround an inlet mixer forming a slip joint with the diffuser without disassembly. Slip joint clamps drive or bias the inlet mixer in a lateral direction largely perpendicular to the axial orientation and end of the diffuser to achieve a desired preload force in the inlet mixer and clamp connection. Clamp arms include rotatable halves that, when joined, form a complete fill between an inner surface of the diffuser and outer surface of the inlet mixer. A lateral drive pushes the inlet mixer against the clamp and may include a resistive element. An accessible set of guide ear bolts and lateral driving bolts permit exterior manipulation to axially mount or laterally bias the clamp in the slip joint.Type: ApplicationFiled: May 9, 2016Publication date: November 9, 2017Inventors: Hampton W. Lane, Jack T. Matsumoto, Ahdee Q. Chan, Emanuel Klein, David J. Bell
