Abstract: A wall panel system. The wall panel system comprises a panel and a panel support handle. The panel comprises a first locking member biased towards a locked configuration and moveable to an unlocked configuration. The wall panel also comprises a first panel support handle guide The panel support handle defines an abutment. The panel support handle is configured to engage with the first panel support handle guide at a first position on the first panel support handle guide such that the abutment is spaced apart from the first locking member. The panel support handle is configured to be moveable along the first panel support handle guide to a second position on the first panel support handle guide such that the abutment engages with the first locking member to move it from the locked configuration to the unlocked configuration.

Abstract: A felting apparatus including a carrier for externally carrying precursor material to rotate with the carrier. A drive is for driving the carrier and the precursor material to rotate. One or more agitators agitate the rotating precursor material. Each agitator is a non-driving agitator.

Abstract: An inventive solid state drawing die has shaping walls that define a shaping channel and that, in the course of solid state drawing, direct polymer composition along a drawing path. Each cross section of the drawing path (and, hence, polymer composition in the drawing path) is non-circular, substantially proportional to one another, contains a centroid that lies on a substantially straight line parallel to the drawing direction and all cross sectional dimensions are 1.5 millimeters or more.
