Abstract: POWER SUPPLY FOR POWER LINE CARRIER COMMUNICATION SYSTEMS             ABSTRACT OF THE DISCLOSURE Apparatus for powering a signal amplifier or repeater connected to the primary or high-voltage portion of a power distribution system.  Oscillator and amplifier circuits are energized by power from the secondary or low-voltage portion of the power distribution system.  The oscillator and ampli-fier circuits are connected to the primary winding of an air-core transformer.  A capacitor is also connected to the primary winding to make the primary circuit of the air-core transformer resonant at the frequency of the oscillator.  The secondary winding of the air-core transformer is connected to a reson-ating capacitor and to transformer and rectifier circuits which convert the AC voltage into DC voltage for powering the signal amplifier.  Electrical isolation between the high-voltage and low-voltage portions of the distribution system is provided by the separation distance between the primary and secondary windings of the air-core transformer.  Sufficient electrical energy is transferred between the primary and secondary windings of the air-core transformer by energizing the primary winding with a high-frequency voltage from the oscillator and amplifier circuits.  The mutual inductance between the primary and secondary windings of the air-core transformer is low enough to permit reasonably efficient power transfer when the oscillator and amplifier circuits operate at high frequencies.

Abstract: RCA 68,346 TELEVISION FREQUENCY SYNTHESIZER FOR NONSTANDARD FREQUENCY CARRIERS                Abstract of the Disclosure A television receiver tuning apparatus includes a programmable phase locked loop (PLL) to synthesize local oscillator signals having frequencies appropriate to tune the receiver to standard frequency carriers respectively allocated to conventional channels.  Local oscillator signals having frequencies appropriate to tune the receiver to nonstandard frequency carriers such as may be generated by a master antenna or cable television distribution system can also be provided.  The PLL derives a first control voltage to control the frequency of the local oscillator signals having a range sufficient for a particular band to tune the receiver to all the channels in the band.          During the reception of a nonstandard frequency carrier, a programmable divider associated with the PLL is in-cremented to change the local oscillator frequency in a predetermined range around the standard local oscillator frequency corresponding to the selected channel.  The predetermined range is determined by the maximum expected deviation between respective nonstandard and standard frequency carriers.  The frequency incremented local oscillator signal is mixed with the received signal to derive an intermediate frequency signal having a carrier incremented in a frequency range corresponding, in direct relationship, to the frequency range of the frequency incremented local oscillator signals.  An automatic fine tuning (AFT) circuit including a frequency discriminator develops a discriminator signal representing the fre-quency deviation of the incremented intermediate frequency RCA 68,346 carrier from the standard picture carrier frequency (e.g., 45.75 MHz).  The discriminator voltage is amplified to provide a second control voltage with approximately the same amplitude range as the first control voltage.  When the amplitude of the second control voltage is changing in the right direction to allow AFT control and is sub-stantially the same as the amplitude of the first control voltage for the presently selected channel, the voltage controlled local oscillator is decoupled from the first control voltage and is coupled to the second control voltage.                              - 1a -

Abstract: PARTICULATE FLAVORING MATERIALS  AND METHOD OF PRODUCING SAME      Abstract of the Disclosure Particulate flavoring materials are provided having a flavoring agent fixed in a particulate matrix containing a di-saccharide and certain carbohydrates of hydrophilic colloids and starch hydrolysates.  The ratio of the disaccharide to the carbo-hydrate in the particulate matrix is such that at least about 30% flavoring agent per total particulate matrix is entrapped in the matrix and less than about 4% flavoring agent per total matrix is unentrapped on the surface of the particles.  The particulate flavoring materials herein provided thus effectively fix flavoring volatiles for storage without vaporization and/or chemical alteration of the flavoring power.  The high quantity of flavoring agent contained per unit weight of matrix material in the flavoring particles provides significant economics with regard to storage, transportation, and manufacturing costs.      Particulate flavoring compositions are prepared by forming an aqueous mixture of a flavoring oil, a disaccharide and a carbohydrate of the hydrophilic colloid and hydrolysed starch type, and then spray-drying the aqueous mixture under the influence of heat.  The method produces particulate flavoring compositions in a very effective manner and enables substantial amounts on the order of about 30 to 60% flavoring agent entrap-ment in the particulate matrix.  The method also provides for very efficient utilization of flavoring agents by the fixation or all or nearly all of the flavoring agent starting material in the particulate end-product.

Abstract: Abstract of the Disclosure A combustible mixture of air and minute fuel drop-lets is produced for supply to the cylinders of an internal combustion engine.  The engine includes a carburetor having a main air passageway in it, and an intake manifold inter-posed between the engine and the carburetor.  The intake manifold includes at least one wall defining a plurality of fluid passageways operatively connected to the carburetor and to the combustion chambers of the engine.  A throttle structure is mounted in the intake manifold.  The combustible mixture is formed by introducing liquid fuel into a stream of intake air and uniformly distributing the fuel in the air by passing the air and fuel mixture through a constriction to increase the velocity of the mixture to sonic speed.  The constriction occurs at the throttle structure in the mani-fold.  The area of constriction and the amount of the fuel entering the air stream are adjustable for correlation with engine demand.  After passing through the constriction, the air/fuel mixture is accelerated to supersonic velocity and thereafter decelerated to subsonic velocity to produce a shock zone where the fuel droplets are believed to be further subdivided.  The supersonic and subsonic mixture speeds are obtained at the outlet of the throttle structure in the manifold. Thereafter, the mixture is inducted into the combustion chambers Or the engine.  Preferably, the throttle structure includes a tubular device having at least one end movably mounted in the intake manifold.  A plate either is suspended in or forms a part of the intake manifold.          The plate and tubular structure coact to provide the con-striction, supersonic and subsonic zones of mixture flow.
