Abstract: ABSTRACT OF THE DISCLOSURE   A television tuning system is provided which employs a frequency synthesizer system for establishing the tuning of the receiver.  A first programmable frequency divider controlled by a reversible counter is connected between the output of a reference oscillator and a phase comparator to which the output of the local oscillator, after passing through another programmable frequency divider, also is applied.  The phase comparator output is a tuning voltage used to control the tuning of the local oscillator.  A logic circuit is coupled to sense predetermined relationships of signal from a picture carrier detector, a sound carrier detector, an AFT signal, and the presence of vertical synchronization signal components for changing the count in the reversible binary counter to adjust the first programmable frequency divider to compensate for channel frequency offsets which may occur in excess of the pull-in range of the AFT circuit.  To enable operation of the receiver in a fringe area, where it may be desirable intentionally to mistune a channel slightly, manual fine tuning control logic circuitry is employed to dis-able the frequency offset logic circuit and to permit changing the count of the reversible counter by the viewer to fine tune manually the receiv-er as desired.  This then provides an improved frequency synthesizer tuning system for a television receiver which includes a provision for adjusting the synthesizer loop for frequency offsets of the received signal and, in addition, has a provision for permitting manual fine tuning adjustments of the frequency synthesizer loop.

Abstract: GUIDE VANE ASSEMBLY FOR REVERSE FLOW COOLED DYNAMOELECTRIC MACHINE            Abstract of the Disclosure A reverse flow cooled dynamoelectric machine is provided with guide vanes and a guide vane mounting assembly comprising means for mounting and positioning the guide vanes, and means for directing the flow of cooling gas from the fan to the cooler. A fan nozzle ring is attached to the machine stator. An outer vane support ring is fixed to the fan nozzle ring and is provided with a circumfer-entially extending dovetail recess along its inner face. An inner vane support ring is spaced radially inwardly from the outer support ring and is also provided with a dovetail recess along its inner face.          A plurality of guide vanes having inner and outer dovetail end portions mating with the dovetail recesses of the inner and outer support rings are held in place by the support rings. An annular rub strip is disposed adjacent to the outer support ring and is fixed to the fan nozzle ring. The rub strip includes a serrated inner face which, with the tips of the fan blades, produces a seal. A flow guide ring is provided adjacent the fan rub strip and acts to smoothly direct the flow of cooling gas away from the fan toward the cooler. The guide vanes and the mounting assembly are formed from electrically non-conducting materials to prevent induced heating of the assembly from stray flux at the end of the dynamoelectric machine.

Abstract: Abstract of the Disclosure Monitoring of the recirculated atmosphere of an oxygen pulping reactor to determine when the inflammability level of combustible gases in the reactor atmosphere has reached a predetermined percentage of the lower explosive limit (LEL) of the reactor atmosphere in terms of combustible organic vapors and carbon monoxide is disclosed. Continuous or discrete samples of the reactor atmosphere are taken at spaced regions, and the samples are applied to: (1) flamed ionization detectors, which determine theconcentration of combustible organic vapors (e.g., aliphatic, olefinic, aromatic, acetylenic, alcohols, aldehydes, ketones, etc.) in the samples;  and, (2) carbon monoxide analyzers, which determine the concentration of carbon monoxide in the samples.  The outputs of the flame ionization detectors are calibrated in terms of percent LEL for the contributing combustible organic vapors and, thus, provide percent combustible organic vapor LEL information.  The outputs of the carbon monoxide analyzers are calibrated in terms of percent LEL based on the carbon monoxide in the samples.  The outputs of the flame ionization detectors are compared and the highest percent output is applied to an alarm and recording subsystem.  These outputs are also compared to determine if they are close to one another.  If the comparison indicates that a substantial difference exists, a differential sensor activates a further alarm to denote a wide variance that may indicate a faulty detector channel.  Similarly, the outputs of the two carbon monoxide analyzers are compared and the highest percent output is applied to an alarm and recordingsubsystem.  Also, if the outputs are substantially different a differential indicator is activated.  In addition, in an alternative embodiment, the highest flame ionization output is summed with the highest carbon monoxide analyzer output and the result is applied to a controller that continuously controls the position of a vent valve, as well as to an alarm and recording subsystem.  Finally, an oxygen analyzer is provided for measuring the oxygen concentration of at least one of the reactor atmosphere samples.

Abstract: STRUCTURAL CONNECTION              Abstract of the Disclosure A structural connection between adjacent ends of vertically superimposed precast columns in a structural frame-work of precast beams and columns.  As in precast columns of the prior art sections of tubing are cast in the columns and extend longitudinally of them.  However, the tubing at one end of the columns, rather than terminating at or just beyond the column end face, projects outwardly of the column a substantial distance, preferably through an opening formed through a beam at a beam-column intersection where the column joint is formed, and one end of a spindle is received in this portion of tubing and also in a second portion of tubing projecting only a slight distance from the opposite end of the adjacent column.  A washer or washers may be loosely attached to or merely slipped over the spindle to engage the opposed ends of the tubing and transfer loads from an upper to a lower column.  This construction provides shorter length spindles and a direct transfer of loads from upper to lower columns.
