Abstract: ABSTRACT OF THE DISCLOSURE            A multi-channel generating system wherein each channel is provided with a permanent generator (PMG) coupled directly to the output of a constant speed drive.  An overrunning clutch is located between the PMG and the generator.  The frequency of the signal from the PMG is proportional to the output speed of the constant speed drive.  A circuit provides underspeed information if the speed, as indicated by the PMG, drops below a minimum speed represented by a reference voltage.  The underspeed information controls the excitation and de-excitation of the generator exciter voltage and a line contactor switch.

Abstract: TITLE:  PORTABLE X-RAY UNIT WITH         SELF-CONTAINED VOLTAGE SUPPLY     Abstract of the Disclosure An X-ray unit is provided having a self-contained high voltage supply including a pair of capacitors charged through diodes from a pair of transformer secondary windings and connected in series through the windings to the anode and cathode of an X-ray tube. Switching means are provided for operation either in a first mode in which the alternating voltages across the secondary windings are in phase and in which the output voltage is equal to the sum of the DC volt-ages across the capacitors to be substantially constant, and a second mode in which the alternating voltages across the second windings are out of phase and in which they are added to produce a pulsating output voltage having a peak value which is approximately double that of the substantially constant voltage obtained in the first mode of operation.

Abstract: HIGH SPEED PRINTER HAMMER ASSEMBLY            Abstract of the Disclosure A high speed printer is provided having a plurality of aligned hammer assemblies for directing hammers at a moving charac-ter band for printing characters responsive to the hammers driving against the character band.  The hammer assembly has a striker arm pivotedly mounted to a striker assembly frame and which acts as an armature when driven by a pair of magnets.  The magnets are at-tached to the striker assembly frame on opposite sides of the striker arm and on opposite sides of the pivot point for the striker arm so that simultaneously actuating both magnets pulls the striker arm for actuating the hammer.  Each magnet has a single coil, with one of the magnets having a reverse polarity from each adjacent magnet on an adjacent assembly, while the other magnet has the same polarity to avoid cross-talk and to increase the speed of the printer.  A pressure-sensitive tape is bonded to the striker armature to provide a residual air gap between the arma-ture and magnet poles and improvements are made in the hammer guide combs, return plunger, and the platen.

Abstract: BALANCED CONTROL WAVEFORM FOR  REDUCING INVERTER HARMONICS                      Abstract of the Disclosure A particular control waveform actuates the half-bridge switching elements of a three-phase power inverter in such a manner as to balance harmonic cancellation between waveform notching and low impedance filtering in obtaining a substantial sinusoidal output signal.  The control waveform allows a small amount of lower order harmonics which inherently decreases the higher order harmonics generated by the notches in the control waveform so that a small filter, e.g. a five percent filter, can be used which eliminates the need for voltage regulation under various current loads and yet both the unregulated voltage fluxations and overall harmonic content of the output signal is well within acceptable tolerances for use by a public utility or the like.  At the same time, the control waveform employs a relatively low per cycle switching rate which minimizes the number of off-on transitions of each of the high-current, solid state switches in the inverter thereby retaining high inverter efficiency.

Abstract: Abstract A  digital color television system is described in which only one chrominance component of the video color television signal is transmitted for each television line, and digital delay means is employed for delaying at least one of the two chrominance components I and Q of the color television signal so that the delayed chrominance component can be added to the trans-mitted television signal to produce output signals having both chrominance components.  The system includes a recording apparatus for recording the di-gital color television signal on a record which may be an optical or magnetic record, and a playback apparatus for playing back the recorded signal to a television receiver or other utilization device.  A gate means is provided in the recording apparatus for selectively transmitting a conventional digital color television signal having two chrominance components as an altered di-gital television signal having only one chrominance component per line which is different on alternate lines.  As a result, the amount of information stored on the record is greatly reduced.  In one embodiment of the system, the two chrominance components I and Q are recorded between luminance words Y with different chrominance components recorded in alternate television lines. A single digital storage means such as a shift register is used in the play-back apparatus.  In the other embodiment, the chrominance components are re-corded at the end of each television line in the horizontal blanking region, with different chrominance components being recorded in alternate lines. This necessitates two digital storage means of the recirculating type in the playback unit, one storage means for each of the two chrominance components because both are recorded out of their proper sequence with the luminance words.
