Abstract: Abstract of the Disclosure Magnetic bubble domains are propagated in a magnetic medium in a desired direction using magnetic fields which have no spatial gradients. This is in contrast with conventional propagation techniques where magnetic overlays have to be used with applied magnetic fields in order to move domains.  Depending upon the wall magnetization configurations in the domains, those domains are propagated by using, for example, a combination of a steady magnetic field and a magnetic field which varies with time, such as a pulse field or a sinusoidal field.  This type of propagation is termed automotion.  Bubbles which can automate are generated and detected in the magnetic medium using the principals of automotion. Embodiments a:- shown for representation of information using different types of bubbles, and in particular it is shown how to discriminate among bubble domains having wall configurations having a common winding number s.  In a particular embodiment, a modulated bias field is superimposed on a steady magnetic field in the plane of the magnetic medium.  Depending upon the direction of the in-plane magnetic field and upon the wall magnetization configuration of the bubbles, the bubbles can be made to move in different directions regardless of the directions of the modulated bias field.

Abstract: Abstract of the Disclosure The invention provides a machine for drilling tap holes for shaft furnaces, particularly of blast furnaces, wherein the machine can be moved to the working position and withdrawn therefrom in one single movement, in contrast to the two independent movements of prior art mechanisms.  The apparatus therefore requires only a single driving mechanism, instead of two independent driving mechanisms.  The apparatus consists of an inclined support  column on which a bar carrying a drilling mechanism is mounted by means of a radial arm extend-ing from the support column.  The support column is inclined at an angle to the vertical in dependence upon the space available around the furnace for movement of the radial arm and bar from a working position to a retracted position and vice versa.  The bar is mounted on the arm for rotation in the vertical plane to vary the angle of inclination of the tap hole.  The hydraulic driving device for moving  the machine between its two positions comprises means for limiting the amplitude to which it can be extended, and for insuring that the extreme extended position which is thereby selected corresponds to the operating position of the tool holder bar in order to avoid inaccuracies in drilling.  Means for maintaining the pressure of the hydraulic fluid during the operation of the drilling machine may consist of rigid jointed piping, or alternatively a flexible conduit which is mounted on a wind-up reel.

Abstract: ABSTRACT OF THE DISCLOSURE       A constant voltage square wave inverter drives a load connected as the damping element in an otherwise high Q, resonant matching circuit.  The frequency of the inventer is maintained near the resonant frequency of the load circuit to provide substantially constant load power.         The frequency of the inverter operation may be main-tained near load circuit resonance by forcing commutation of the square wave output voltage as the rate of change of load current is substantially zero.  The inverter output voltage may also be commutated as the peak current reaches a predetermined reference value to stabilize inverter operation for loads which cannot accept real power.

Abstract: TRACTION MEANS WITH ELECTRODYNAMIC VEHICLE SUSPENSION FOR           HIGH-SPEED LAND TRANSPORT                     ABSTRACT OF THE DISCLOSURE            Disclosure is made of a traction means with electro-dynamic suspension of a vehicle, intended for high-speed land transport and comprising a synchronous linear motor whose excit-ing winding is mounted on the vehicle and at the same time serves as the exciting winding for electrodynamic suspension of the vehicle, whereas the three-phase armature winding of said synchronous linear motor extends horizontally along the track and is a single-layer winding with one turn for the pole and phase.  In the active area, the conductors of the armature wind-ing are made as strips parallel to the track plane and having a width up to one third of the pole pitch.  The exciting winding induces eddy currents in said strips on the side of the vehicle, which eddy currents ensure electrodynamic suspension of the vehicle.  Traction means of this type can be used in the future in high-speed urban and suburban transport.

Abstract: SOLID STATE MICROWAVE POWER SOURCE FOR USE IN AN             ELECTRODELESS LIGHT SOURCE                 ABSTRACT OF THE DISCLOSURE    A solid state microwave power source for providing micro-wave power to excite an electrodeless lamp is designed so as to provide an acceptable impedance matching characteristic during lamp warm-up when the lamp impedance is high and changing with temperature to provide sufficient power to the lamp during the running state when the lamp impedance is matched to the source.          The microwave power source includes a dc power source providing power at variable levels, a microwave oscillator receiving the dc power to produce a microwave signal, and a microwave power amplifier.  The oscillator has a transistor in a common base configuration, a microstrip capacitive feedback element to sustain oscillations, and an output impedance matching arrangement formed from microstrip.  The microwave signal is amplified in the solid state power amplifier having a power transistor in a common base configuration.  An impedance matching section between the amplifier and the input of a termination fixture for the lamp includes a length of transmission line which trans-forms the input impedance of the fixture to a level at the collector of the power transistor in the amplifier so as to maximize the power delivered to the lamp at reduced power levels while maintaining the collector voltage within a safe limit.

Abstract: A B S T R A C T           This disclosure pertains to the production of self-converged color CRT display systems, and in particular to a method of reducing the effects of off-axis deflection defocusing of electron beams in such systems.  The disclosed method comprises installing in the neck of each color CRT bulb a three beam in-line-type electron gun whose mechanical and electrical design parameters are such that the beams in their free fall state have a selected nominal value of underconvergence at the screen which is such that substantially the entire population of production tubes is underconverged.  On the neck of each tube is installed a self-converging  yoke which establishes, in addition to main deflection magnetic  field components, an astigmatic field component which self-converges said beams, but which undesirably introduces astigmatic deflection defocusing of the beams when deflected off the tube axis.  Static convergence of said beams at said screen effected by establishing a static astigmatic quadrupolar magnetic field component common to all three beams and opposite to said astigmatic yoke field component which, while accomplishing the desired static beam convergence, deliberately introduces an astigmatic distortion of said beams. The distortion is a function, for each tube, of the free fall underconvergence value for that tube and at least partially compensating the deflected beams for the deflection defocusing of the beams by the oppositely directed astigmatic yoke field component.
