Granted: 1991-01-29
Abstract: BACKFLOW PREVENTING DEVICE             Abstract of the Disclosure A hose connection vacuum breaker backflow preventing device for installation on the discharge nozzle of a water faucet for preventing reverse water flow into the faucet which may possibly contaminate the water supply. The device includes a unitary tubular body defining an unobstructed passageway with threaded female inlet and male outlet connections at opposite ends thereof. An integral shoulder is formed interiorly of the passageway and a pair of exhaust ports open radially I outwardly through the body from the passageway upstream of the shoulder.          A valve assembly within the passageway is spring-biased into a seated position closing communication between the inlet and outlet ends of the passageway while permitting fluid communication between the outlet end and the ports for draining any reverse water flow. The valve assembly is yieldable to an operating position under the force of pressurized fluid flow into the inlet passageway end to open communication with the outlet passageway end, while a resilient valve washer contacts the interior shoulder to close communication between the passageway and the ports to prevent water leakage.

Title: Disk file with air filtration system
Inventor: HATCHETT MICHAEL R
IPC: G11B23/02
Filed: 1987-04-15
Granted: 1991-02-26
Abstract: ABSTRACT      A disk file of the kind employing a vented hub assembly and slotted spacers between disks to provide a passage for circulatory airflow and employs a filter assembly extending circumferentially around the axial region of the hub assembly.  The primary path for airflow is from a high pressure region at the periphery of the disks, through the filter assem-bly into the vented hub assembly and out again via the slotted spacers.  A parallel leakage path between the filter itself and the hub assembly is limited by making the separation between a substantially planar surface of the filter assembly and the adjacent disk uniform and very small.  Airflow rates through the filter are consequently enhanced.
