  • Patent number: 7497493
    Abstract: A carrying rack for transporting sporting or work equipment over a pickup truck bed while utilizing relatively lighter weight materials is disclosed. The carrying rack utilizes the space above the pickup truck bed so the pickup truck bed may be enclosed with a tonneau. The carrying rack incorporates tracks which are easily installed and removed without requiring drilling or other modifications to the pickup truck bed. The carrying rack tracks allow for uprights and cross members to be attached when in use. The carrying rack is mounted to the pickup truck bed so the tonneau cover may be rolled up without removing the cross members or uprights. The location of the cross bars and uprights on the carrying rack can be adjusted along the length of the carrying rack tracks, thus allowing for attaching equipment such as bicycle carrier, ski carrier, cargo basket, ladder, or other types of equipment. In some embodiments, the lateral position of the tracks can be varied as well.

  • Patent number: 6292330
    Abstract: A cleaning cartridge for cleaning a reciprocating read/write head of a tape drive. The cartridge includes a cleaning tape and cleaning segments that cooperate to clean the tape contacting surface and the air-bleed slots of a read/write head as it moves thereagainst. The cleaning segments are preferably mounted on a carrier that may be displaced to accommodate different models of tape drives having various read/write head projection depths, and which may include a resilient member for urging the cleaning segments towards the read/write head with a predetermined amount of force.

  • Patent number: 6097572
    Abstract: A cleaning cartridge for cleaning the read/write head of a tape drive having at least one stationary cleaning device with filaments, fibers or strands positioned to loosen and remove debris from the air bleed slots of the read/write head. The cleaning cartridge cleans the air bleed slots at the same time as cleaning the tape contact surface of the read/write head.

  • Patent number: 6038111
    Abstract: A cleaning cartridge for cleaning the read/write head of a tape drive having at least one stationary cleaning element with filaments or strands positioned to loosen and remove debris from the air bleed slots of the read/write head. The cleaning cartridge cleans the air bleed slots at the same time as cleaning the tape contact surface of the read/write head.

  • Patent number: 5991127
    Abstract: A cleaning tape for cleaning a magnetic tape head and tape path, having a non-abrasive cleaning surface with abrasive segments applied on the non-abrasive surface to form an alternating pattern. The abrasive segments may be angled across the surface of the non-abrasive cleaning surface. The abrasive segments loosen adhered debris and the non-abrasive segments carry the loose and loosened debris away from the head and the tape path.

  • Patent number: 5859755
    Abstract: The present invention provides an apparatus using dry cleaning techniques for cleaning a read/write head of the contact transducing type such as found on computer data backup tape drive systems. The apparatus includes a housing enclosing a supply reel holding a supply of cleaning tape, a takeup reel for holding used or soiled cleaning tape, and a gear train for transmitting rotary power at a reduced rotational speed from an external power source such as the tape drive capstan to the takeup reel. The gear train includes a plurality of gears that constitute a gear reduction system such that the cleaning tape can be driven past the head at an effective cleaning speed which is substantially less than the normal read/write speed of the tape drive. The apparatus further includes a movable shutter mechanism for blocking one of a pair of light paths between a light emitter and a light sensor forming part of the tape drive system, thereby providing a unique signal to the tape drive.

  • Patent number: 5703742
    Abstract: A tape driving cleaning cartridge having a housing with recognition openings, a slide mechanism slidably movable to cover one recognition opening while leaving the other open. The slide mechanism is manually movable between the two positions. If additional recognition openings are employed, multiple slide mechanisms may be used.
