Abstract: ABSTRACT OF THE DISCLOSURE          A magnetic drive assembly includes a housing having a pair of end flanges, an annular drive member containing a plurality of drive members and internally thereof a driven member containing a plurality of driven magnets.  The drive and driven members are bearingly supported by the end flanges so that rotation of the drive member results, through-magnetic interaction, on rotation of the driven member.  A barrier separates the driven and drive members and extends between the end flanges to hermetically seal the driven member.  The barrier is formed from a plurality of abutting axially adjacent annular laminations held in axial compression by the end flanges, the laminations being formed of a non-magnetic material.  In one embodiment the laminations have a chevron shape in radial cross-section whereby adjacent laminations are nestable with each other.  In a second embodiment the laminations are rec-tangular in radial cross-section and are additionally supported by a thin wall non-magnetic sleeve extending between the end flanges.  The laminated barrier reduces power loss and heat generation due to eddy currents generated by the magnetic flux and still provide sufficient stability in shear and end thrust for use in pressure vessel applications.

Abstract: AUTOMATIC DECELERATION CONTROL APPARATUS          ABSTRACT OF THE DISCLOSURE         A circuit incorporated in a braking system for allowing a pilot to select a desired rate of deceleration and to cause the aircraft, upon landing, to achieve and maintain the selected deceleration rate.  Fundamentally, the circuit includes a selector switch for selecting the desired rate of deceleration and uses a linear decelerometer signal having an out-put corresponding to the instantaneous rate of actual deceleration of the aircraft. Comparator circuitry com-pares the actual and desired rates of deceleration and provides an error signal to high and low rate circuits which charge a storage capacitor which in turn, through a buffer and power drive circuitry, regulates the associated control valve.  When the difference between the actual and desired rates exceeds a particular level, the high rate circuit controls the charging of the capacitor.  The low rate circuit operates when the difference between the actual and desired rates is below the particular level, and is operative to cause the actual rate of deceleration to asymptotically approach the desired rate. There is also included an initialization circuit for quickly filling the brake cavities to initiate the braking operation.
