Abstract: A loudspeaker cone body made of paper may include a chemically-bound nanomaterial, such as a carbon nanotube. The carbon nanotube may be chemically bound to a functionalizing agent having a chemical group chemically bound to one or more papermaking additives, such as a sizing agent or a wet strength agent, a dry strength agent, a resin or cellulose-containing papermaking stock material typically present in a paper loudspeaker cone body, such as pulp. Acoustic-related loudspeaker performance characteristics such as stiffness to weight ratio and an acoustic damping of the loudspeaker cone body may be altered by incorporation of the nanomaterials chemically bound to the loudspeaker cone body.
Abstract translation: 由纸制成的扬声器锥体可以包括化学结合的纳米材料，例如碳纳米管。 碳纳米管可以化学键合到具有与一种或多种造纸添加剂化学键合的官能化剂，例如上浆剂或湿强度剂，干强度剂，含树脂或纤维素的造纸原料通常 存在于纸扬声器锥体中，如纸浆。 声学相关的扬声器性能特征如刚度与重量比以及扬声器锥体的声阻尼可以通过结合化学地结合到扬声器锥体的纳米材料来改变。

Abstract: A removable cutterhead insert (18) for use in a helical cutterhead (10) for an industrial woodworking machine, the helical cutterhead (10) including a generally cylindrical portion (16), a plurality of circumferential, spaced grooves (17) extending into the cutterhead body from the periphery of the cylindrical portion (16) and adapted to receive the removable cutterhead inserts (18), and fasteners for removably securing the cutterhead inserts in the grooves (17); the cutterhead insert (18) includes a mild steel insert body (22) and two blade units (24); the insert body (22) having raised portions having triangular pockets formed therein so as to have two inwardly-facing flat portions, a hole to receive the fasteners for removably securing the cutterhead insert in the grooves between the inwardly-facing flat portions and two bolt holes to secure the two blade units to the insert body; and the blade units are triangular with cut-off corners (36) each including a blade edge (38) and configured so as not to occlude the countersunk hole and to have the blade edges disposed to align with the blade edges of other blade units.
