To calibrate, the build platform is moved laterally in the horizontal plane and the extruder nozzle is moved downward toward the build platform. While moving the nozzle downward, the velocity of the build platform or the power required to move the build platform in the horizontal plane is monitored. A drop in velocity or an increase is power required to move the build platform is detected when the extruder nozzle contacts the build platform due to kinetic friction. The vertical height of the extruder nozzle is then set or calibrated relative to the build platform based on the position of the extruder nozzle when the contact was detected.Type: GrantFiled: June 20, 2016Date of Patent: December 18, 2018Assignee: NEW MATTER, INC.Inventors: Norvan Gorgi, Steven Schell, Derek Schulte

Patent number: 10137622Abstract: Injection molding of plastic materials by an apparatus comprising at least one injector including a valve pin displaceable in a controlled manner between a closed position and an open position by an electric rotary actuator. At least one step is provided of detecting the value of the torque developed by the electric rotary actuator when the valve pin is in the path from the closed position to the open position, and the torque value detected is used to pilot the molding process.Type: GrantFiled: April 30, 2018Date of Patent: November 27, 2018Assignee: INGLASS S.p.A.Inventor: Maurizio Bazzo

Patent number: 10035290Abstract: An extrusion blow molding method includes detecting an exit velocity of a tube exiting a head during a blow molding cycle for forming the tube. A melt accumulator receives part of the melt conveyed by an extruder or discharges melt in addition to the melt conveyed by the extruder in dependence on the detected exit velocity. The melt accumulator discharges melt if the detected exit velocity is less than a target value for the exit velocity and receives melt if the detected exit velocity is greater than the target value for the exit velocity.Type: GrantFiled: November 29, 2013Date of Patent: July 31, 2018Assignee: KAUTEX MASCHINENBAU GMBHInventor: Martin Klein

Patent number: 9914247Abstract: A method for infusing gas into a thermoplastic material includes positioning a sheet of a thermoplastic material into a vertical or substantially vertical position; positioning a sheet of a gas-permeable material into a vertical or substantially vertical position; and winding together the positioned sheet of thermoplastic material sheet and the positioned sheet of gas-permeable material to form a roll of the thermoplastic material interleaved with the gas-permeable material, the interleaved roll having a longitudinal axis oriented in a vertical or substantially vertical position. The method also includes exposing the interleaved roll to an atmosphere of a gas pressurized to infuse the thermoplastic material with the gas, while the longitudinal axis of the interleaved roll is oriented in a vertical or substantially vertical position; and then unwinding the gas-infused interleaved roll, while the longitudinal axis of the interleaved roll remains in a vertical or substantially vertical position.Type: GrantFiled: February 28, 2013Date of Patent: March 13, 2018Assignee: Dart Container CorporationInventor: Krishna Nadella

Patent number: 9728793Abstract: There is provided a technique that readily performs positioning of a joining member relative to a strip member during conveyance. A joining device 100 joins a gas diffusion layer 7 with a first catalyst electrode layer 2 of a strip body 5r which is a continuous strip member of a membrane electrode assembly 5, while conveying the strip body 5r. A controller 101 of the joining device 100 obtains a detection time td based on a detection signal of a catalyst layer detector 130 when a front end 3e of a second catalyst electrode layer 3 placed on the strip body 5r passes through a detection point DP. The controller 101 subsequently obtains a joining position reach time tt based on the detection time td when the gas diffusion layer 7 reaches a press point PP of joining rollers 152. The controller 101 starts conveying the gas diffusion layer 7 by means of a transfer at a conveying start time ts that is obtained based on the joining position reach time tt and a specified speed pattern of the transfer 141.Type: GrantFiled: February 7, 2014Date of Patent: August 8, 2017Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hiromu Takai, Yutaka Sugie
