Abstract: GRADIENTLESS PROPULSION OF MAGNETIC BUBBLE DOMAINS            USING MODULATED IN-PLANE FIELDS     Abstract of the Disclosure Magnetic bubble domains are propagated in a magnetic medium in a desired direction using in-plane magnetic fields which are time varying but which have no spatial gradients.  In applications such as information storage, the need for conventional propagation structures, such as offset conductor loops, patterned magnetic elements, and patterned ion implantation regions is reduced.  Bubble domains having unwinding pairs of Bloch lines in their wall magnetization can be moved by applying appropriate in-plane magnetic fields, without the need for spatial gradients or variations in the magnetic field normal to the plane of the magnetic medium.  The continuous movement of these bubble domains occurs by a cyclic process where the Bloch lines switch between two configurations, in an asymmetric way in response to the time varying in-plane field.

Abstract: CONTROLLED-WIDTH-SYNCHRONIZATION OF MAGNETICALLY RECORDED PIXELS     ABSTRACT OF THE DISCLOSURE         Synchronization of pixels in tracks of magnetically recorded information is provided by insuring that pixels are of substantially uniform width, particularly the first recorded pixel in each recorded track.  Uniform width of pixels, particularly first pixels, is achieved through a triggering circuit which begins recording the first pixel of each track only when the record head is at the proper location.  The circuit is capable of delaying the recording of a track to within a pixel length of time and divides the pixel length of time to some predetermined plurality of track recording starting points.

Abstract: FAIL-SAFE CIRCUIT FOR TAP-CHANGING    TRANSFORMER REGULATING SYSTEM     ABSTRACT OF THE DISCLOSURE         A tap-changing transformer system, utilized for voltage regulation of the line potential applied to a load from a source of energy, has a non-arcing switch to protect tap contacts during a tap change.  A fail-safe circuit is utilized to determine that the non-arcing switch and its associated circuitry are operating properly before a movable tap contact is transferred from one stationary tap to another.          In the event that the fail-safe circuit detects an improper operation of the non-arcing switch, the source is connected directly to the load to preclude the passage of any load current through the tap-changing transformer.  A particular form of transfer switch useful in effecting the connection of the source directly to the load employs a current-limiting impedance arrangement.

Abstract: Abstract Noise Elimination and Refractory Period Control in Demand Pacers Oscillator pulses are coupled to a counter, the ultimate count interval of which causes an output amplifier to produce a stimulating pulse and also to reset itself.  A refractory control flip-flop is also thereby reset, and blocks demand mode resetting pulses for the refractory period.  A second counter is resettable by the input amplifier, and defines a count interval during which noise pulses are rejected.  A second flip-flop is responsive to the second counter and to the refractory flip-flop selectively to reset the first counter based on demand pacing criteria.

Abstract: PNEUMATIC VALVE APPARATUS          Abstract of the Disclosure A pneumatic valve apparatus comprises a cylindrical structure having opposite, outwardly facing faces. A plurality of two-position valves are located in the structure at regular angular intervals at positions about the axis of the cylindrical structure. The valves are subject to mechanical actuation by axial displacement. A spindle co-axial with the axis has a passageway for the flow of air toward each axial end of the spindle. A pair of pawls are carried by the spindle, one on each side of the faces, for limited axial displacement and rotatable with respect to the cylindrical structure about the axis. The pawls are angularly displaced from each other so that when one pawl is aligned with a valve, the other pawl is angularly and axially misaligned. Resilient means (spring 6) urge the pawls axially away from the faces. A pair of pistons on each side of the faces simultaneously respond to air pressure received from a passageway in the spindle to drive both pawls inward toward both faces against the force of resilient means or springs urging them away from the faces.    In operation the pawls are advance with the spindle about the axis selectively to position the upper pawl over, or the lower pawl under, a selected valve. Then pneumatic pressure may be applied through the passageway to drive the pistons and the pawls together. Thus any selected digital valve may be driven by the appropriate pawl to the selected digital position while the other pawl exercises an idle stroke because of the angular displacement.

Abstract: ABSTRACT OF THE DISCLOSURE    An induction heating apparatus includes a DC power source, a transistor for generating a trigger current in response to a base drive pulse applied thereto, and a resonant load circuit including a work coil and a capacitor for generating in response to the trigger current an oscillating resonating current when the switching device is turned off, and which current is passed through a diode connected in inverse parallel relation with the transistor.  A current transformer is provided to detect the load current.  A low voltage detector senses a nearly zero voltage at the collector of the transistor and triggers a ramp generator to generate a ramp voltage which is compared with a reference voltage to generate a train of base drive pulses for application to the transistor.  To control the base drive pulses at a variable duration in accordance with an inductive load, the reference voltage is varied as an inverse function of the sensed load current.

Abstract: A STATIC INVERTER EMPLOYING AN ASSYMETRICALLY ENERGIZED INDUCTOR     ABSTRACT OF THE DISCLOSURE           A static inverter employing an inductor and an electrical gain element for intermittent assymetric energization of the inductor from a dc source is described. Reliable intermittent operation of the gain element, typically a power transistor, is achieved by use of three feedback windings which in response to saturation of a branch of the core of the inductor but before full core saturation, discontinue regenerative feedback and then apply degenerative feedback.  This turn off mechanism protects the transistor from high current stresses. Passive means are provided such as a capacitor for momentarily storing the energy or diode means for coupling the energy back to the  source or to the load to protect the transistor from the high voltage surge and the energy release when current flow in the inductor is interrupted. Energy stored in the capacitor may be used for transistor commutation.

Abstract: PRESSURIZED WASTE WOOD FURNACE SYSTEM                 ABSTRACT     A forced draft fan creates within a furnace fuel cell a pressure which is high enough to provide a pressure gradient effective to force the combustion gases from the cell all the way to the dryer.  The combustion gases are provided by waste wood products which are forced by a special feeding system into the fuel cell against the resistance of the relatively high air pressure within the cell, to create a burning pile.  The feeding system blocks most of the smoke and combustion gases from back-feeding through the fuel passageway, and then removes the part that is not blocked.  The combustion gases during the drying process become wet.  A part of these wet gases are vented at the dryer but a recirculation fan effects the return of a portion to a blending chamber where they are mixed with hot combustion gases to be again directed to the dryer.          The other portion of the wet gases is directed to the combustion chamber for augmenting its operation.
