Patent number: 11872573Abstract: An aperture plate is manufactured by plating metal around a mask of resist columns having a desired size, pitch, and profile, which yields a wafer about 60 ?m thickness. This is approximately the full desired target aperture plate thickness. The plating is continued so that the metal overlies the top surfaces of the columns until the desired apertures are achieved. This needs only one masking/plating cycle to achieve the desired plate thickness. Also, the plate has passageways formed beneath the apertures, formed as an integral part of the method, by mask material removal. These are suitable for entrainment of aerosolized droplets exiting the apertures.Type: GrantFiled: August 9, 2022Date of Patent: January 16, 2024Assignee: Stamford Devices LimitedInventors: Brendan Hogan, Hong Xu

Patent number: 11844342Abstract: The present invention provides an electronically controlled valve in each air distribution line for delivering product-conveying air to a boom section of an agricultural machine. The valves can be used to balance airflow between lines by controlling back pressure at the boom sections. In one aspect, an electronically controlled butterfly valve can be installed in each air line between a fan's plenum outlet and a dry product delivery meter. Each valve can be configured to allow some flow when in a closed position. This could be achieved, for example, by configuring a valve plate with a circular perimeter shape that has a smaller diameter than an inner diameter of the line or tube in which the valve plate is mounted.Type: GrantFiled: March 30, 2020Date of Patent: December 19, 2023Assignee: CNH INDUSTRIAL AMERICA LLCInventors: Rex Ruppert, Randy Lindemeier, Jeffrey Scot Martin, Jeremy Amundson
