摘要： Disclosed herein are methods and pressure vessels for solid-state microcellular processing of thermoplastic rolls and sheets. In one embodiment, the present invention is directed to a method for making a gas impregnated interleaved roll, which method comprises: providing a pressure vessel having an internal pressure chamber and a rotatable shaft horizontally positioned within the pressure chamber; placing an interleaved roll about the rotatable shaft and within the pressure chamber, wherein the interleaved roll is made from a thermoplastic material sheet interleaved together with a gas-channeling material sheet; pressurizing the pressure chamber to a selected pressure; rotating the rotatable shaft having the interleaved roll thereabouts (thereby rotating the interleaved roll) while under pressure for a selected period of time; and depressurizing the internal chamber to yield the gas impregnated interleaved roll. In other embodiments, the invention is directed to multi-chambered pressure vessels for gas impregnation of thermoplastic rolls, sheets, and films.

摘要： A head tensioning mechanism (10) for varying the tension on a drum head (14) during play is disclosed. In a preferred embodiment, the head tensioning mechanism (10) incorporates a pair of paddles (52) extending along opposite sides of the drum body (28) such that the paddles (52) may be squeezed between the legs of the player for variably adjusting the head tension in response to the squeezing pressure applied by the player. A device for supporting the drum in an upright position and incorporating a treadle (82) for operating the variable head tensioning mechanism (10) in response to foot pressure is also disclosed.
