Abstract: A system for the extraction of vocal content from a musical track. A hardware platform and a multimedia software application are provided that are suitable for use in playback of the musical track. A filter software unit then dynamically intercepts the musical track in the hardware platform prior to its use there in playback. The filter software unit suppresses the vocal content from the musical track to create an instrumental track, and it passes the instrumental track on for use in playback immediately or after some period of storage.

Abstract: A device to produce lumber from logs, wherein the device is arranged to be attached to a portable chain saw so as to be adjustable to provide various board thicknesses. The device comprises a frame structure having a plurality of laterally spaced support struts secured in spaced relationship to each other by longitudinally arranged rod members. At least two rod members include front and aft drive rollers which are operably connected by a drive-train system including a power motor arrangement whereby the device, along with the chain saw, is continuously fed in a longitudinal cutting direction along the length of the log being cut. The thickness of the lumber being cut is determined by the setting of a thickness control dial unit operably mounted in conjunction with rack and pinion members, wherein the rack members are directly attached to the chain-saw bar.
