Abstract: BLANK, S. L. 7-15-16 MAGNETIC DEVICES UTILIZING GARNET       EPITAXIAL MATERIALS            Abstract of the Disclosure The application describes magnetic bubble devices using new magnetic materials.  The materials are based on the prototype garnet (YIG) in which the dodecahedral site is substituted with lanthanum and samarium or europium.  These mixed garnet compositions can be tailored to support very small bubbles, or to increase bubble mobility, or a desired combination of both.  The new compositions are based on the recognition that lanthanum can be incorporated in the dodecahedral site to adjust the crystal lattice parameters while leaving the functional properties of the layer essentially unaltered.

Abstract: ABSTRACT A range-gated radar system which includes a phase modu-lator that modulates an r.f. generator with a signal which may be binary coded.  In a preferred embodiment, the binary signal is a periodic signal of 2N-1 bits per period.  Starting at some arbitrary point in the sequence, K contiguous bits are transmitted then M contiguous bits are passed over, then K more bits are transmitted, and so on.  The quantities M + K and 2N-1 have no primary factors in common.  The radar system may be a doppler radar system using balanced digital processing which involves separating the upper an lower sideband components of modulation that exist in the return radar signal as a result of the motion of scatterers and subtract-ing them.

Abstract: MAGNETIC ROLLER     ABSTRACT    A magnetized roller is mounted on the hall doors of an elevator system.  A metal vane is attached to an ele-vator car door.  The hall doors and car doors are opened together and the roller is magnetically pulled against the vane.  The magnetic pull holds the roller on the vane and a mechanical connection between the two doors is thereby provided.  Through this mechanical connection the car door provides supplemental closing force to the hall door.  The roller comprises a ring which is magnetized by two smaller ring magnets which are located on opposite sides of the ring.  The like or similar poles of each magnet face each other.  The magnets rotate together with the magnetized ring on a shaft.  The pole strength of the magnetized ring at its outer edge, which contacts the vane, is approximately equal to the combined pole strength of the two magnets.

Abstract: TWO-CYCLE ENGINE WITH FUEL INJECTION      ABSTRACT OF THE DISCLOSURE     The invention contemplates electronically controlled fuel-injection for a multiple-cylinder two-cycle internal-combustion engine wherein each cylinder has its own independent crankcase region in which to receive and compress inlet air and fuel, prior to delivery of combustible mixture to the head or combustion end of the cylinder.  Fuel is injected into each crankcase region during only a portion of the stroke involving induced intake of air therein, i.e., during only a portion of the rise of each piston in its approach to top-center position, and while pressure within the crankcase region is relatively uniform.  The time-duration of actual injection is relatively short, thus enabling a plurality of different cylinder injections to be made concurrently, resulting in simplification of fuel-injection  control circuitry.

Abstract: ULTRACOMPACT SELF-POWERED MINIATURE TOY VEHICLE WITH FOUR-WHEEL DRIVE AND UNUSUAL CLIMBING CAPABILITY ABSTRACT OF THE DISCLOSURE A toy vehicle only slightly longer than a "pen-light" battery, and with chassis less than twice the width of such a battery, is able (traction permitting) to climb any grade on which it will not tip over back-ward -- grades up to about 40° -- and to negotiate a vertical step taller than its tire radius. The AA-battery-powered four-wheel-drive vehicle has a small electric motor with a double-ended shaft, and a symmet-rical gearing system consisting of, at each end of the motor, a pinion fixed on the shaft, a spur gear driven by the pinion and driving a worm, and a worm gear keyed to a corresponding axle. The motor, pinions, spur gears and worms, and the upper portions of the worm gears, are aligned along one side wall inside the vehicle chassis, with the battery alongside them occupying the rest of the chassis. Traction and climbing characteristics are enhanced by twice-overscale tires, preferably of open foam, with highly pronounced treads.
