摘要： This invention provides aqueous dispersions of externally chain extended polyurethane compositions terminated by hydrolyzable and/or hydrolyzed silyl groups and containing anionic solubilizing or emulsifying groups, particularly carboxyl groups. The invention also provides methods of making both anionically and cationically stabilized polyurethane dispersions. This invention further provides polyurethane dispersions which are substantially organic solvent free, (e.g. less than about 7 weight percent organic solvent) which cure to water and solvent resistant, tough, scratch resistant, preferably light stable (non-yellowing) polyurethane films. Such films are particularly useful as coatings for wood substrates, including wood floorings, furniture, and marine surfaces.

摘要： A positional locating method and apparatus (10) for measuring distances by accurately determining the transit time of ultrasonic wave bursts (22) between two or more points is disclosed. Timer clocks (60), (62), (64) and (66) are started when each of the bursts (22) is triggered to be emitted from a transmission point (14), and are stopped when a highly defined point (56) in the burst (22) is received at a corresponding receiving point (32), (34), (36) and (38). The highly defined point (56) is determined by first analyzing the burst (22) to identify a particular cycle (54) within the burst (22). That particular cycle (54) is then analyzed to detect the specific point (56) within the cycle (54). Use of multiple transmitters (9312), (9314) and (9316) or receivers (932), (934) and (936) permits the dimensions using ordinary trigonometric calculations. The calculation of position within two or three physical inventive method also has sufficient resolution to permit the calculation of attitudinal data by detecting very fine positional differences in a plurality of reference points located at relatively close distances on a movable marker device (912).

摘要： The disclosure is directed to a method for creating a remnant magnetization on a magnetic tape medium. The magnetic tape is first substantially demagnetized, e.g., erased, by an erasure unit having multiple magnetic elements of alternating polarity. The erased magnetic tape is then passed by a bias magnet that creates a remnant magnetization on the magnetic tape. The remnant magnetized magnetic tape is then passed through a servo write head that writes servo patterns to the remnant magnetized magnetic tape. The bias magnet may be housed within the erasure unit or within a bias unit, and the distance between the bias magnet and the tape path of the magnetic tape may be adjustable to create the desired remnant magnetization on the magnetic tape. The remnant magnetization created on the magnetic tape may be greater than 20 percent to reduce defects in the servo pattern written to the magnetic tape.
