Abstract: A self contained tilt rack video cassette library cabinet containing multiple VCP units with an XYZ motion tape cassette selection and delivery system to computer directed insertion in a subscriber VCP and return after play to a tilt rack library storage bin. The system includes activation means, movie selection means and a TV set at each subscriber location, an address mechanism in the system and a telephone line connection through a duplex modem to a computer having a monitor and keyboard with computer controlling XYZ carrier movement pick up of cartridges from and return to video cassette storage bins, insertion and extraction of selected video cassettes to and from subscriber dedicated video cassette players (VCP). Each VCP has an audio and video output connection to respective modulators each output connected to a combiner mixer. There is also a character-modulator loop connection, and a computer to combiner mixer address transmitter loop along with a character generator modulator loop, with the mixer output connected to address control circuits.

Abstract: A dual power tool, such as a jointer/planer, is disclosed in which the cutting head of the tool is mounted on a common shaft which also serves as the rotor shaft for the tool drive motor. This dual power tool is mounted on a single stand and has a switch enabling only one tool at a time to be operated. A retrofit kit is disclosed for permitting a tool owner to convert a single power tool into a dual power tool.
