Patent number: 11609967Abstract: Method and apparatus for monitoring and diagnosing gun performance is derived that can determine proper gun operation and if not operating properly diagnose potential causes for abhorrent operation. The voltage produced by the gun is sampled in real time and the frequency spectrum produced analyzed using FFT and then reducing the FFT pattern down to a set of numerical values or a signature that can be compared to known signatures for both correct operation and abnormal operation. Using best fit techniques the cause of any abnormal behavior can then be identified. The method can also be used to predict the end of hardware life and aid in production scheduling and spare parts acquisition by providing advanced notice of wear and usage.Type: GrantFiled: May 24, 2018Date of Patent: March 21, 2023Assignee: OERLIKON METCO (US) INC.Inventors: Ronald J.

Patent number: 10760933Abstract: Powder flow conveying from a powder feeder to a process (i.e. thermal spray gun) can have instabilities that can be detected and diagnosed using a hose back pressure. Incorporating a pressure transducer in a powder hose line at a connection of the powder hose line and the feeder allows the back pressure to be measured in real time at a high sample rate to detect instability and aid in diagnosing a cause of the instability. Diagnosis includes identifying periodic oscillations in the powder hose line such as acoustics as well as detecting hose clogging and hose rupture conditions. Once detected, proper corrective actions can be recommended to correct the cause of the instability.Type: GrantFiled: May 31, 2017Date of Patent: September 1, 2020Assignee: OERLIKON METCO (US) INC.Inventors: Ronald J. Molz, Jose Colmenares, Elliot M. Cotler, Samrawit Hermosillo, Cristian Ibanez

Patent number: 10562051Abstract: A hopper assembly includes a hopper configured to contain a feedstock material. A vibration imparting device is arranged inside the hopper and a vibration source coupled to the vibration imparting device. Embodiments of the instant invention are believed to provide various improvements in feeding uniformity by providing various hopper configurations that ensure a more consistently uniform filling of the metering device for a variety of difficult-to-feed materials and not-so-difficult-to-feed materials. One, more or all of these embodiments are also believed to improve accuracy and add precision to control, and, in addition, offer more simplified hopper construction—which is less costly to manufacture and maintain.Type: GrantFiled: December 9, 2015Date of Patent: February 18, 2020Assignee: OERLIKON METCO (US) INC.Inventors: Elliot M.
