Donohoe
Donohoe relates to drum heads and processes for making them.
(Donohoe at col. 1, ll. 8–9.) More specifically, Donohoe
provides a method that “precisely positions and interlocks the
periphery of a drum head membrane within an integral tensioning
hoop.” (Id. at col. 3, ll. 12–15.)
Donohoe also discloses that a drum head membrane may be made
“from a circular disk that has an outer annular region thereof
formed by the simultaneous application of heat and pressure
(thermo-forming) into a curved transverse cross section.”
(Donohoe at col. 5, ll. 48–52.)
