Abstract: ROTATING RING YARN SPINNING OR TWISTING          APPARATUS AND METHOD     Abstract of the Disclosure An air-bearing supported, freely rotated spinning or twisting ring carrying a yarn traveler having radial and cylin-drical air-bearings and an annular plenum cavity in at least one of the cylindrical air-bearing surfaces for generally open, unencumbered and continuous admission of pressurized air to the air-bearings.  The air-bearings communicate through an annularly disposed mutually connecting enlarged air space.  Time delay means is provided for reducing the air supply to the air-bearings at a selected predetermined time after de-energizing the power drive of the apparatus.  A method of controlling yarn tension during stop-off of the apparatus includes the steps of maintaining air pressure in the air-bearings after de-energizing the power drive to the apparatus, continuing to maintain the air pressure while the apparatus and the freely rotating ring decelerate for a predetermined time period, and reducing the air pressure at the end of the time period so that the ring decelerates more rapidly and stops prior to the remainder of the apparatus.

Abstract: ELECTRICALLY ACTUATED AIRCRAFT BRAKES              ABSTRACT OF THE DISCLOSURE           Apparatus for electrically controlling the application and release of aircraft brakes. In one embodiment, the invention includes a slurry clutch controlling a reciprocating member which is oper-atively connected to the pressure plate.  In another embodiment of the invention, a torque motor is adapt-ed to have an armature which comprises a ball screw, the ball screw being in engagement with a longitud-inal drive rod interconnected with the pressure plate.  Rotation of the armature causes the drive rod to move the pressure plate into forceful engagement with the brake disk stack or to retract the same. In yet another embodiment of the invention, a plurality of torque motors are interconnected with a bull gear which is operative for driving the pres-sure plate.  Each of the embodiments of the invention includes apparatus for maintaining a fixed built-in clearance in the brake disk stack of the brake assembly, and are further adapted for utili-zation with antiskid systems by utilizing a device connected to the pressure plate which allows rapid release of brake torque.  Additionally, apparatus is provided which allows a locking of the brake assem-bly while the aircraft is parked.

Abstract: STORAGE ADDRESSING CONTROL APPARATUS                      ABSTRACT      Addressing control apparatus is structured to provide either byte or word addressing of storage organized on a word basis.  The storage address register is made shiftable whereby for byte operations it is shifted, and the bit shifted out of the register is used for byte selection.  The contents of the storage address register are used to address storage for both word and byte addressing, and no change is required. The storage access, however, for byte addressing takes place after the shift is completed and the timing is adjusted to account for the shift operation.  Gate control logic is modified to facilitate the byte selection.

Abstract: IMPROVED WHEEL SLIP CONTROL USING DIFFERENTIAL SIGNAL    ABSTRACT OF THE DISCLOSURE     Apparatus for controlling wheel slip in a locomotive driven by d.c. motors which receive power from a diesel driven generator, has sensors which provide signals representing speeds of different driven wheels to a velocity unit.  The velocity unit derives a differential signal representing the difference between the highest and the lowest wheel speeds.  A sensor detects current or power in the generator output and the signal from this sensor is sampled periodically and the latest two sampled values are stored.  The sampled values are compared to provide a creep reference signal.  The differential signal and the creep reference signal are compared and the resulting difference signal is used to control generator output to maximize current during acceleration.
