Abstract: Abstract A field deflection amplifier generates a field deflection current in a field deflection winding.  An LC resonant circuit is coupled to the deflection winding and to an output switching amplifier.  A control circuit switches conductive states of the amplifier at a line rate, with a 50% duty cycle, to excite the LC resonant circuit into providing a line rate correction current for the field deflection winding.  The control circuit varies the modulation envelope of the field deflection current at a field rate in a generally saw-tooth manner to provide north-south pincushion correction. When used in conjunction with raster scanning in a square-planar picture tube, the modulation envelope is nonlinearly waveshaped to take into account the aspherical nature of the picture tube faceplate.

Abstract: ABSTRACT     A toy vehicle with a chassis carrying an axle for rotation has a hollow wheel mounted for rotation on the axle.  Openings extend through the peripheral wall of the wheel that normally contacts a supporting surface.  Inside the wheel a spider is secured to the axle for rotation with a number of legs spaced from the axle.  A claw is attached to each of the legs for pivotal movement relative to the leg with the free end of the claw substantially within -the wheel.  The hollow wheel is normally driven on a smooth surface through engagement with the spider-claw subassembly.          However, when the wheel encounters a rough surface or obstruction that tends to cause the wheel to slip, the claws emerge and engage the surface and the vehicle clambers across the obstruction.  Pivotal movement of the claw relative to the leg may be permitted by a "living hinge" which also biases the claw to remain in the wheel.

Abstract: ABSTRACT OF THE DISCLOSURE         Circuitry corrects vertical beam landing errors for color cathode ray tubes.   A digital delay circuit provides horizontal scan line video pixel information at its proper location to produce a distortion corrected raster.  Accurate correction is provided by a combination of scan line offset between the input and output video signals and by sample interpolation techniques that effectively form derived pixels that have an apparent location that corrects the scanning distortions.  The location of the derived pixel relative to the video pixel samples is determined by the selection of the interpolating coefficients.

Abstract: ABSTRACT A bypass blower provides air for combustion and scavenging purposes to a two-stroke diesel engine having an exhaust port from which an exhaust conduit ducts exhaust materials through a particulate trap and thence to the atmosphere.  An air atomizing nozzle is provided for introducing atomized supplemental fuel into the exhaust conduit upstream of the trap and a supply of supplemental fuel and compressed air is provided.  A microprocessor-based control unit is adapted to operate the bypass blower under a condition of reduced bypass during normal operation of the engine.  However, when backpressure in an exhaust conduit rises to a predetermined level due to particulate build-up, the bypass blower setting is changed to increase the amount of bypass of scavenging air in order to reduce the trapped air/fuel ratio and raise the temperature of the exhaust materials.  Compressed air and supplemental fuel are then delivered to the nozzle to promote burning of the exhaust materials and regeneration of the respective trap.  When either the backpressure in the exhaust conduit falls or the temperature of the trap rises, the engine is returned to normal operation.  In one variation, the diesel engine does include a bypass blower, but the trap regeneration temperature is lowered by operating the engine on fuel having an additive which includes one or both of manganese and copper.  In a simplified version, only the bypass blower is provided, and this is operated as described above to increase the temperature of the exhaust materials when particulate build-up is detected through increased backpressure, thus initiating regeneration of the trap.

Abstract: ABSTRACT           Current-mirror circuitry is utilized on a MOS integrated circuit for regulating the amount of current entering the pre-charged nodes of a pre-charged logic circuit.  The current-mirror circuitry involves a series of bias transistors, each extending in parallel with a respective one of the pre-charge transistors, and a bias current circuit.  The bias current circuit is formed by a transistor and a resistance element which are serially connected across the power supply of the logic circuit. The gate of the bias circuit transistor is connected to the gates of the bias transistors, and the current passing through each bias transistor depends upon the relative dimensions between that transistor and the respective bias circuit transistor.  The value of the resistance element determines the amount of current passing through the bias circuit transistor and therefore through the bias transistors.
