  • Patent number: 6389333
    Abstract: An improved navigation and display system especially suitable for small aircraft rapidly determines the attitude (roll and pitch) of an aircraft from measurements made by an inexpensive, single receiver and antenna responsive to signals obtained from a satellite positioning system, e.g., the Global Positioning System. In contrast to conventional attitude navigation systems, which determine and display conventional (body-axis referenced) pitch angle, the present system determines and displays the “pseudo-attitude” or stability axis roll and pitch (flight path) angle, so that the pilot has an instantaneous comprehension of the actual flight path angle of the aircraft without needing to correct for angle of attack as in conventional attitude information systems. A Kalman filter with a short (˜0.5 second) time constant provides data at a sufficient rate (e.g., ˜10 Hz) to enable real-time flight with the system.

  • Patent number: 4925555
    Abstract: An artifical hybrid organ or gland is formed from two serially-interconnected chambers, the first of which comprises an ultrafiltration chamber which forms an ultrafiltrate from the blood stream applied to it and the second of which comprises a cell exchange chamber which, though immunologically isolated by microporous membranes, receives both the bloodstream and the ultrafiltrate and which rapidly exchanges selected constituents with both before they recombine in order to provide a corrected physiological response to constituents in the blood. Additionally, an optional excretory duct may be employed to channel a portion of the treated ultrafiltrate away from the bloodstream.

  • Patent number: 4300866
    Abstract: A one-piece spring washer for use with threaded fasteners such as screws has a self-retention feature whereby, once positioned on the screw, it remains firmly in place. The washer comprises an annular body defining a central aperture for receiving the screw shank and a plurality of thread engaging teeth bent up from the body about the aperture for holding the washer in place. Each tooth has a helical thread confronting edge having a pitch that is steeper than, and in the opposite sense of, the pitch of the screw thread so that the teeth extend crosswise of and grip the crest of the thread. A plurality of spring elements are bent up from the washer body outboard of, but in the same direction as, the teeth. The spring elements, which flex downwardly when the screw is tightened against a workpiece, load the screw axially to resist loosening of the screw.

  • Patent number: 4296286
    Abstract: A self-referencing position switch particularly adapted to respond to the position of an automobile gear shift lever. The switch is responsive to the position of a movable external member relative to a stationary member and includes a pair of housing sections one of which is attached to the stationary member and the other of which defines a track for a movable switch member which follows the movements of the external member and is arranged to close the switch at a selected location along the track. The two housing sections are movable relative to one another in more or less the direction of the track so that by engaging the movable switch member against one or the other end of the track and moving the housing sections relative to one another, the selected location on the track can be correlated with a selection position of the movable member.

  • Patent number: 4276483
    Abstract: A timed electric switch in a housing preferably for direct current loads such as for heating elements in vehicle windows, in which manually closable contacts supply current to the load and also to a digital timing circuit, which completes a circuit from said contacts through a holding solenoid for the contacts. After a predetermined count has been achieved in the timing circuit, the current supply through the holding solenoid is interrupted thereby releasing the contacts. Provision is made for allowing the second and subsequent timing periods to differ from the first timing period by independently supplying potential to the timing circuit, such as through the vehicle ignition switch. Reset of the timing circuit to produce the initial timing period once again is effected by switch off and re-operation of the ignition switch. An illuminated indication is provided, preferably by a light emitting diode, which operates when power is supplied to the load.

  • Patent number: 4270777
    Abstract: A releasable hose fitting comprises a male member that mounts on the end of a flexible hose and a complementary female member that mounts on a hose receiving nipple. The male member includes a pair of arms that extend along the side of the hose and that include inwardly projecting barbs that grip the hose walls to hold the member on the hose. The male member also includes a pair of relatively resilient wings that extend along the side of the hose and that include outwardly projecting noses. The female member has a cup-like configuration including a wall portion defining an entrance opening in which the male member is received. A locking rim is formed on the inside surface of the wall portion. As the male member is pushed into the female member, the wings deflect inwardly until the noses clear the rim, whereupon they snap outwardly and lock behind the rim. The male member is released from the female member simply by squeezing the wings inwardly sufficiently for the noses to clear the rim.

  • Patent number: 4132145
    Abstract: A washer-nut assembly wherein a sheet metal nut is rotatably coupled within an annular plastic washer. The nut has an inner threaded barrel portion for engaging the threads of a cooperating bolt, an outer barrel portion shaped for engagement by a tightening tool and a frusto-conically shaped skirt portion extending outwardly from the outer barrel portion. The washer includes a central through-aperture and an inboard surface near one end of the washer that defines a seat for the skirt portion of the nut. The axial height of the washer is substantially greater than that of the nut so that the nut is recessed within the washer. The nut is coupled to the washer by skiving material from the inboard surface of the washer to form tongues that overhang the skirt portion of the nut. The tongues retain the nut within the washer yet permit free-spinning of the nut and washer relative to one another.
