Abstract: An anti-reflecting film is made from a polymeric film substrate consisting of cellulose acetate, polyamide or polyester. The substrate is coated with at least two polymeric layers. An outer layer is comprised of a fluorine containing polymer. Between the outer layer and the substrate is an intermediate layer of an organometallic polymeric layer. The organometallic polymeric layer is comprised of the condensation product of a metal alkoxide and a polymer reactive with the metal oxide.

Abstract: A multiple format hand held label printer includes a processor, a memory, a keyboard, a thermal printer and an advance mechanism for a tape of successive labels carried on a substrate. The processor reads operator keyboard inputs and formats both machine readable bar code data and alphanumeric data for the printer. The printer is actuated to imprint such information on successive adhesive backed labels. In addition, the processor stores label print information and sequentially changes print indicia to meet particular requirements. The processor communicates with a system processor for coordinated inventory control, market study or other functions.

Abstract: A system for testing video equipment includes a video cassette tape cassette which carries prerecorded test signals and patterns such as NTSC standard color bar test patterns, dot patterns, convergence patterns and the like. Playback of the video tape enables one to determine if a video player, recorder, television receiver or monitor is in need of adjustment and permits adjustments without complex test equipment. The test signals are recorded in segments at different speeds to test speed playback functions of the player or recorder and may include a visual countdown for synchronization of subsequent recording. To produce the video tape cassettes with the prerecorded test signals and patterns, a test pattern generator is utilized to provide a signal which is fed to a video recording head. The video recording head records the signals and patterns on a leader portion of each tape prior to loading into a cassette.
