Abstract: A disk drive 100 capable of receiving a cartridge 20 having a disk 42 with a diameter of about 3.5 inches which can contain at least 105 megabytes of data includes an operating mechanism 112 for initiating and controlling the positioning of an actuator arm 176 upon which is mounted a read/write transducer 178. The position of a spindle motor 224 which is used to spin up the disk 42 contained in the cartridge 20 to an operating speed, the locking of the cartridge 20 in the disk drive 100 in an operating mode and the ejection of the cartridge 20 from the drive 100. The operating mechanism 112 can function to eject the cartridge 20 whether or not the drive 100 is powered up in order to be able to remove the cartridge 20 and transport it to another disk drive 100 or to a secured location in a plane substantially parallel to the disk 42 contained in the cartridge 20.

Abstract: A robotic library design for a mechanism that picks and places storage cartridges having a robotic shuttle assembly that moves parallel to the storage cartridges, a moveable stage that moves perpendicular to the storage cartridges, and a pair of gripping finger to retain, extract, and deposit the storage cartridges within the library subsystem. The pair of gripping fingers, initially biased in a closed position, are cammed open by the edges of the storage cartridge upon the moveable stage's approach and close upon engagement with the storage cartridge's notched recesses. The storage cartridge is moved within the library subsystem and is delivered to its destination when a solenoid activates a mechanical trigger that releases the pair of gripping fingers. The moveable stage completes the storage cartridge's delivery and resets for its next instruction.

Abstract: A system for priming a carburetor for an internal combustion engine which includes a pulse pressure conduit leading from an engine crankcase to a significant portion of a carburetor and a cowl located manually operated valve for opening this conduit during cold starting of an engine. The valve is arranged to have at least three positive positions including "closed" and a plurality of regulated open positions.
