Publication number: 20210037728Abstract: A drip emitter is provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. Water enters the emitter through a first inlet and proceeds into a first chamber. When the water pressure is above a predetermined level, a one-directional valve opens to allow fluid flow past the first chamber, through a tortuous path flow channel, and through an emitter outlet. A second inlet is used to compensate for water pressure fluctuations in the supply tube to maintain output flow at a relatively constant rate. Water enters the second inlet and presses a flexible diaphragm toward a water metering surface to provide pressure-dependent control of the output flow. A copper member is mounted to the emitter over the emitter outlet to prevent plant root intrusion into the emitter outlet.Type: ApplicationFiled: October 22, 2020Publication date: February 11, 2021Inventors: Rick Mavrakis, Brian Pope, Samir Shah, Christopher Leland O'Neal, David R. Laybourn

Patent number: 7086426Abstract: An ergonomic cable tie installation tool includes a generally pistol-shaped housing including a grip which depends from a barrel. Pivotally connected to the lower region of the grip is a trigger linkage of a trigger mechanism. The trigger mechanism also includes an intermediate linkage pivotally connected to the trigger linkage. The intermediate linkage is supported in the housing. The intermediate linkage is, in turn, connected to a tensioning mechanism also supported in the housing. The tensioning mechanism couples the intermediate linkage to the cable tie. Pivoting the trigger linkage toward the grip, normally by the hand of a user, causes the intermediate linkage to pivot resulting in the tensioning mechanism producing an increased tension in the cable tie. The trigger linkage is oriented relative to the grip such that pivoting it toward the grip requires the stronger fingers of the user's hand to travel more than the weaker fingers thereby improving the ergonomics of the tool.Type: GrantFiled: July 7, 2003Date of Patent: August 8, 2006Assignee: Thomas & Betts International, Inc.Inventors: Joey D. Magno, Jr., Brian A. Pope
