Abstract
An environmental conditioning and safety system for use with disk-type mass memories includes a barometric sensor, a replaceable desiccant cartridge, a finned heat sink cover plate, a breather filter, check valving and a flow restrictor. The system is especially suited for use in harsh environments, such as may be encountered in oil and gas exploration and in military use.
Claims11
An environmental control appartus for a disk-type mass memory device having at least one sealed head/disk compartment, said apparatus comprising means for exchange of air between said compartment and the atmosphere, means for drying the air drawn in by said air exchange means, means for filtering the air drawn by said air exchange means, means for dissipating heat from within said compartment, means for preventing rapid depressurization of said sealed compartment, means for sensing and signalling a low barometric pressure condition within said compartment and means for interrupting the operation of said mass memory device, said sensing and signalling means comprising an altitiude pressure switch disposed within said sealed compartment, said switch including means for generating an interrupt signal for transmittal to said mass memory device.
