Abstract: PROCESS FOR PRODUCING ELEVATED TEMPERATURE     CORROSION RESISTANT METAL ARTICLES                Abstract Of The Disclosure A process for providing coatings on metal articles whereby the articles will be resistant to corrosion at ele-vated temperatures.  The process involves the application of an overlay on an article surface, the overlay comprising a ductile metal of a composition normally resistant to corro-sion at elevated temperatures.  An outer layer of aluminide or metal which is resistant to corrosion at elevated tempera-tures but which is subject to embrittlement at such tempera-tures is applied to complete the coating.  Porosity in the coating is then eliminated and a high integrity corrosion resistant coating not subject to cracking is obtained by heating the article in a gaseous atmosphere to elevated tem-perature and simultaneously applying isostatic pressure to the article.

Abstract: ABSTRACT TITLE "VIDEO SIGNAL RECORDING AND REPRODUCING APPARATUS AND METHOD"     In a VTR for use with SECAM signals, the signals are recorded in H-alignment in a plurality of parallel tracks on a record medium in a configuration such that field intervals in which the same chrominance component (i.e. B-Y or R-Y) occurs in successive tracks are aligned to reduce the effect of crosstalk.  To avoid difficulties arising in stop and slow motion reproduction where the heads may scan a path which is skewed relative to the tracks, the chrominance components in every other frame are delayed by lH by a delay line      prior to recording while the chrominance components in the remaining frames are delayed by 1H by a delay line .      To ensure correct sequencing of a switch,     associated with the second delay line a tone-burst from an oscillator      is inserted during the vertical blanking period of every fourth frame.

Abstract: ABSTRACT OF THE DISCLOSURE There is described a plume reduction system for a compressor driver gas turbine which drives gas through a pipeline.  Another turbine is used in a refrigerant system which has a first heat exchange mechanism for extracting heat from the gas and a second heat exchange mechanism which rejects the heat from the refrigerant system.  The heat from the condensing coils of the second heat exchange mechanism is used to warm air at the base of a dry-type cooling tower.  Air drawn between the con-densing coils by induction is mixed with the over satura-ted air from the exhaust of the gas turbine.  This mixing decreases the dew point of the effluents from the tower. The effluents are propelled into the atmosphere and form a plume only upon reaching their dew point which is above an altitude at which weather inversion conditions effect the plume.

Abstract: ABSTRACT OF THE DISCLOSURE        For removing undesired gaseous components, e.g., SO2, from hot combustion gases (from carbonaceous fuels) by scrubbing with a regenerable absorbent, the scrubbing is conducted with a liquid physical absorbent, e.g., dimethylformamide, at a temperature less than 0°C.  The cooling requirements of the scrubbing process are supplied by an absorption-type refrigeration unit.  The hot combustion gases, prior to scrubbing, are cooled in indirect heat exchange, first with air in an upper temperature range cooling zone, and then with cold combustion gas purified by the scrubbing in a lower temperature range cooling zone.  The heat from the resultant heated air may be used as (a) preheated air for combustion or may be used as (b) an energy source for the operation of the absorption-type refrigeration unit or may be used as both (a) and (b).  A heat pump may be used to supplement the absorption-type refrigeration unit.  Other aspects include, for example, special regenerator design and absorbent regeneration steps.

Abstract: COMPENSATED DUAL INJECTOR DRIVER            ABSTRACT     A  compensated  dual  injector  driver  circuit  for controlling the current to either of a pair of electro-magnetic  solenoid  fuel  injectors  is  disclosed.   The driver  circuit  includes  a  pair  of  analog  bilateral switches operably connected to the control terminals of two driver transistors whose power terminals are coupled serially with the coils of the injector solenoids.   A driver amplifier generating a current control signal for the driver transistors is connected to a common input of the two switches.  Either of the switches is selected for closure by a logical input from a select line thereby choosing the individual injector to be energized.   The driver amplifier in response to the leading edge of a control pulse regulates the conductance of the selected transistor with the current control signal to initially draw current through the injector coil until it reaches a peak value.   At the time the peak current is attained, the driver amplifier then switches the control current to a holding value.  The peak and the holding current levels are measured by a negative feedback loop from a sense resistor commonly connected in series with each set of coils and driver transistors to indicate the magnitude of current therethrough.   The circuit further includes a' means  for  controllably  collapsing  the  magnetic  field stored in the injector coils when the injector driver transistors are turned off in response to the trailing edge of the control pulse.  Compensation is provided to the driver amplifier for altering the hold level current in accordance with variations in the battery voltage. The  differing  levels  of  hold  current  with  changing battery voltage  will modify  the closing  time of  the injector oppositely  to those changes produced  in the opening times by the battery voltage.
