Abstract: A removable magnetic data storage cartridges incorporates antiferromagnetically coupled (AFC) media and may be used with a data drive to push the capacity point of removable hard platter based magnetic storage to 35 GB for a single platter 2.5? form factor product. The removable magnetic data storage cartridges incorporating AFC media represents an equivalent increase in the areal density of removable magnetic data storage cartridges on the order of 13×.

Abstract: A cartridge for a magnetic disk drive has a rigid shell and a flexible door which covers an opening through which read/write heads engage the recording medium. The flexible door is guided outside of the shell to an open position as the cartridge is inserted into the drive. A projection on a flexible arm in the drive catches a hole in the flexible door to open it as the cartridge is inserted into the drive. The door along the outside of the cartridge conserves space so that the recording medium can be large for a given form factor drive.

Abstract: The invention encompasses a system that utilizes radio frequency circuitry in combination with microprocessor devices and specially designed software to provide an improved structure and operation for the monitoring, protection and control of inventory assets. Generally, the system is embodied in a system controller unit, one or more interrogator devices and multiple transponder units. The system controller unit may be a personal computer (PC) based device for effecting the control and monitoring of the system's operation. In addition, the system controller unit serves as a data collection device and as an alarm device. The interrogator device(s) incorporate a transceiver controlled by microprocessor circuitry within the interrogator devices. The transponder units also include a radio transceiver and microprocessor circuitry. The transponder units are attached to a container or item to be monitored and protected.

Abstract: A head loading mechanism for a removable cartridge disk drive comprises a support base fixedly mounted in the drive, and a moveable member movably attached to the support base via a pair of elongate flexures. The moveable member has a ramped surface adapted to engage a suspension arm at the distal end of an actuator. A read/write head is mounted on the suspension arm. The moveable member moves upon the flexures in tandem with the actuator as it moves toward and away from the edge of a disk inserted in the drive. The moveable member carries the suspension arm of the actuator to the edge of the disk, at which point the suspension arm can ride up and down the ramped surface of the moveable member in order to load the read/write head onto the surface of the disk and then subsequently to unload the read/write head from the disk.

Abstract: In a magnetic disk drive heads are loaded and unloaded onto the magnetic disk by wings attached in close proximity to the magnetic heads. The wings ride on opposed profiles to separate the heads so that they can travel on either side of the disk and the heads are then brought together properly onto the disk. As the heads are withdrawn from the disk, they are separated by the opposed profiles and then the heads are parked on a cleaning pad.

Abstract: A method and apparatus for automated smoking to replicate a predetermined draw profile of a smoking article is disclosed. In preferred embodiments, the smoking apparatus is digitally controlled and includes simulated flexible lips which are closed during puff phases of a recorded draw profile and which are open during smolder phases of a recorded draw profile. The apparatus can also include an automatically acting lighter and an improved control system for a human mimic smoking machine.

Abstract: A magnetic disk drive for writing and reading data to and from a magnetic disk contained in a cartridge which is inserted through an opening in the disk drive includes a drive motor rotated on a yoke by a manually operated shaft having a handle on one end and a cam on the other end. A flat diaphragm switch is operated by a rotation stop on the shaft to indicate when the motor is in the loaded position of engagement with the disk.

Abstract: This invention relates to adducts of salts of polymerizable tertiary amines with acrylic compounds illustrated by acrylamide and acrylonitrile; to polymers and copolymers containing said adducts and to processes for preparing them. This invention also relates to the use of said polymers and copolymers, particularly in the clarification of turbid waters by flocculation or flotation of oil and/or suspended solids. In the preferred embodiment, the quaternary adduct monomer is: ##STR1## where X is an anion, preferably halide such as chloride or carboxylate such as acetate; and polymers and copolymers containing units thereof.
