  • Patent number: 6818597
    Abstract: Liquid water soluble polymer suspensions in non-aqueous solvents are extremely stable over long periods of time with minimum separation of the solvent and no hard packing of the dispersed water soluble polymer. The suspensions enable a user to rapidly add the suspension to water, being mixed at low speeds, without the formation of lumps or fisheyes and without generating fugitive dust in the process. The suspensions are environmentally safe and biodegradable. Unlike many other liquid polymer suspensions, the suspensions exhibit minimal oil or grease upon dilution. They contain no surfactants that can add to the oil and grease determination. The suspensions and the fluids produced by diluting the fluids to a working concentration of the water soluble polymer exhibit low toxicity to marine organisms and to humans. The suspensions can be manufactured from ingredients suitable for use in personal care applications such as cosmetics, shampoos and the like.

  • Patent number: 6743756
    Abstract: Liquid suspensions of particles in non-aqueous solvents are extremely stable over long periods of time with minimum separation of the solvent and no hard packing of the dispersed particles. The suspensions enable a user to rapidly add the suspension to water and to mix at low speeds without generating fugitive dust in the process. In addition, a liquid dispersion can provide an easy to use liquid containing higher concentrations of the active dispersed phase than can be accomplished by simply preparing an aqueous solution of the dispersed phase. Alternatively, highly water-soluble particles may also be suspended which have poor storage, freeze/thaw, or heat/cool stability. In some cases, liquid dispersions can yield controlled release of the dispersed phase because the dispersed phase is not in aqueous solution. The suspensions are environmentally safe and biodegradable and may be used in environmentally sensitive applications, such as for oil well treating fluids for offshore areas.

  • Patent number: 6697229
    Abstract: In order to provide a head transfer mechanism capable of absorbing a play of a head assembly not only in a thrust direction but also in a radial direction as well as a head actuator assembly and a tape drive using the same, the head transfer mechanism comprises a lead screw with a thread ridge, a head elevation guiding member, a preload bushing arranged in a hollow opened portion of a head lift, and a compression coil spring for applying the head lift with a pressing force in an axial direction of the lead screw. The head elevation guiding member comprises as an integral structure a head lift on which the head assembly is mounted and a head guide having a thread groove engaged with the lead screw and serving to move the head lift up and down along a rotation center axis following the rotation of the lead screw. In the head elevation guiding member, the head assembly is given a biasing load in a radial direction of the lead screw.

  • Publication number: 20030189783
    Abstract: A staggered calibration track comprising a plurality of calibration tracks for use positioning a tape drive tape head for reading and writing data to and from multiple data tracks. The staggered calibration track is written by positioning the write head to a predetermined location and moving the tape media horizontally as the vertical position of the tape head is incremented in a stepwise alignment. Locating one of the plurality of calibration tracks is accomplished by positioning the read head at the predetermined location corresponding to the edge of the particular calibration track and moving the tape media horizontally as the read head output is recorded. The particular calibration tracks vertical position is derived using the average read head output.

  • Publication number: 20030107836
    Abstract: A lateral tape sensor for a tape drive having a tape head that is not capable of moving vertically as quickly as tape media, wherein the sensor senses lateral movement of tape media as it moves along a tape path between a storage reel and a take-up reel. The lateral tape motion sensor comprising a means for sensing the position of at least one edge of the tape media and a means for comparing the at least one edge position to predetermined thresholds to determine if the tape media moved laterally. When the lateral movement exceeds predetermined thresholds, the tape drive processor and control circuits respond to prevent accidentally overwriting data previously written on an adjacent track during a write operation, to adjust the tape head to locate data being read following lateral tape motion that occurs during a read operation or to warn the user of poor tape media quality.

  • Patent number: 6572046
    Abstract: The present method for unlocking a single reel tape cartridge locking mechanism in a tape cartridge load operation aids the release of the tape cartridge locking mechanism by manipulating the supply reel motor which is engaged to the single reel tape cartridge in a manner that causes the stuck tape cartridge locking mechanism to release. In order to aid the release of the tape cartridge locking mechanism during the tape cartridge loading procedure, the supply reel motor is operated cyclically to cause the supply reel to vibrate. This vibration is held for a predetermined period of time. At the end of the vibration cycle, the tape drive attempts to pull the tape cartridge leader out of the tape cartridge. If the tape drive again detects that the tape cartridge locking mechanism is not released, it repeats the vibration sequence. The drive can execute a predetermined number of attempts to release the tape cartridge locking mechanism in this manner.

  • Publication number: 20030066922
    Abstract: A sliding door assembly for a singe reel tape cartridge for enclosing the tape media and retracting the leader tab when the tape cartridge is not in use. The sliding door assembly includes a sliding door to enclose the tape media, an auxiliary leader retractor to retract the leader tab, and an actuator integrally connected between the sliding door and the auxiliary leader retractor.

  • Publication number: 20020195513
    Abstract: The single reel tape cartridge with tape reel centering features provides one or more features to center the tape reel with respect to the interior surfaces of the tape cartridge housing and a rotatably driven feature, such as a drive chuck, in the tape drive that rotates the tape reel. The single reel tape cartridge with tape reel centering features provides mechanical positioning and centering of the tape reel with respect to the drive chuck of the tape drive when the tape cartridge is in any orientation and constrains lateral movement of the tape reel to prevent the tape reel from contacting the interior surfaces of the tape cartridge housing. This is accomplished by the use of a spring that applies a bias force to press the tape reel against the drive chuck in the tape drive, which rotates the tape reel. One end of the spring is seated in a spring sleeve that is formed in the center of the interior surface of the top section of the tape cartridge housing. The other end of the spring engages the tape reel.

  • Publication number: 20020195512
    Abstract: A method for detecting slippage in a tape path, and re-calibrating a sensing assembly in a tape storage device to account for the slippage. The method includes sensing a position of one of a supply reel and a take-up reel. In response to sensing the position of the supply reel or take-up reel, sensing a position of a guide roller. The position of the guide roller corresponds to the position of the guide roller when the position of the supply reel or the take-up reel is sensed. In response to sensing the position of the guide roller, the tape media is wound through the tape path between the supply reel and the take-up reel. In response to winding the tape media through the tape path, a second position of the one of the supply reel and the take-up reel is sensed. In response to sensing the second position of the one of the supply reel and the take-up reel, a second position of the guide roller is sensed.
