Abstract: Method and apparatus for forming thick wall plastic components laminated with formable decorative film layers. A thermoformable thick wall plastic sheet in the range of 0.065 to about 0.300 inches thick over at least half its area is provided having a thermoformable decorative dry film coating on one side forming an outer surface of the laminated sheet. The sheet is peripherally supported in an open center rack, heated in one or more ovens to forming temperature and formed by a combination of compression and, preferably, vacuum forming with subsequent trimming of excess material to form a finished component with a high quality finish suitable for automotive body use. The compression and vacuum forming steps may be interchangeably performed in order and provide for high quality finish on the outer surface with shaping of reentrant wall portions on the inner side. Any suitable form of laminated sheet may be formed by the apparatus and method.

Abstract: The present invention is directed to a bass-tone device for use with a piano. The device comprises a housing which can be mounted on a piano above the keyboard of the piano. A plurality of switches are mounted in the housing, and each of the switches has an engaging portion which extends from the housing and contacts a key of the piano when the key is in its normal undepressed state. The engaging portion of each of these switches moves to change the state of the switch in response to the depressing of the corresponding piano key. A bass-tone generator is mounted in the housing and the switches are connected to the generator. The bass-tone generator generates bass-tone signals in response to the change of state of the switches, which change states in accordance with the depression or raising of the piano keys.
