Latest Patents
John E Oldis holds a patent for "Methods and apparatus for tensioning sheet material." This patent describes a process where an electret sheet is clamped on an apertured support, allowing a sheet portion to stretch across the aperture. A tension-producing ring is then advanced against the sheet portion to create increasing tension. Concurrently, a loudspeaker emits constant-amplitude sound waves, causing the sheet to vibrate. When the vibration amplitude reaches a predetermined value, the advancement of the ring is halted, and the sheet portion is adhered to another ring, retaining the existing tension. This innovative method is crucial for creating electret diaphragms used in electret microphones.
