Patent number: 9926951Abstract: Energy regeneration system does not affect operation of a hydraulic actuator except when a relief valve is operating, by connecting an actuator hydraulic line to a regeneration hydraulic motor with a small pressure loss during regeneration, and ensures holding pressure when the energy cannot be regenerated. A first valve device disposed between actuator hydraulic lines and a regeneration hydraulic motor, has a throttle passage capable of increasing pressure in the higher pressure side actuator hydraulic line to a set pressure of the relief valves. A second valve device disposed in parallel with the first valve device between the actuator hydraulic lines and the regeneration hydraulic motor, is switched from a close to an open position by pressure between the first valve device and the regeneration hydraulic motor when pressure between the first valve device and the regeneration hydraulic motor increases to approach the set pressure of the swing relief valve.Type: GrantFiled: July 24, 2014Date of Patent: March 27, 2018Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Takatoshi Ooki, Seiji Hijikata

Patent number: 9926952Abstract: A flow conditioner for displacing and mixing fluid flow to minimize the effects of thermal gradients on the accuracy of a transit time ultrasonic flowmeter having a first portion adapted to be disposed in the pipe and extending inward toward the center of the pipe in a downstream direction with respect to the fluid flow relative to the pipe's inner surface. The conditioner has a second portion adapted to be disposed in the pipe and in juxtaposition with the first portion. The second portion extending inward toward the center of the pipe in an upstream direction with respect to the fluid flow relative to the pipe's inner surface. An apparatus for determining fluid flow in a pipe having ultrasonic transducer sites. A method for determining fluid flow in a pipe. A method for affecting fluid flow in a pipe.Type: GrantFiled: June 10, 2016Date of Patent: March 27, 2018Inventors: Christopher B. Laird, Gregor Brown

Patent number: 9926955Abstract: A latch for coupling a first object to a second object is disclosed comprises a primary block coupled to the first object. A locking cam is rotatably coupled to the primary block. A cam track having a sloped surface is in the locking cam. A locking stem slideably engages the primary block and traverses the locking cam. A cam pin is coupled to the locking stem. The cam pin slidably engages the sloped surface for displacing the locking stem between an extended position and a retracted position. A stem head is coupled to the cam pin. A secondary block is coupled to the second object. A cam channel is in the secondary block for receiving the locking stem. A head receiver is in the secondary block for engaging the stem head. The extended position defines an unlocked position and the retracted position defines a locked position.Type: GrantFiled: August 7, 2015Date of Patent: March 27, 2018Assignee: Taylor & Lego Holdings, LLCInventors: Alan Taylor, Joel Chartier
