Abstract: ABSTRACT OF THE DISCLOSURE           A transformer differential relay monitors the current flowing through the primary and secondary windings of a power transformer and disconnects the transformer from a power source feeding the transformer whenever the magnitudes of these currents indicate a fault condition in the transformer.  First and second current transformer generate primary and secondary winding voltage signals representative of the magnitude of the current flowing through the power transformer primary and secondary windings, respectively.  A solid state restraint signal generator is responsive to the primary and secondary winding voltage signals and generates a restraint signal representative of the magnitude of the larger of the primary and secondary winding currents, respectively, at each measurement instant.  An operate signal generator is responsive to the primary and secondary winding voltage signals and generates an operate signal repre-sentative of the magnitude of the vector sum of the currents flowing through the power transformer primary and secondary windings.  Finally, means are provided for disconnecting the power transformer from the power source when the magnitude of the operate signal operates above a predetermined percentage of the restraint signal.

Abstract: ELECTRIC HEATING SYSTEM WITH PROPORTIONAL  TIMER HAVING A CYCLE OF FIXED DURATION        Abstract of the Disclosure A heating system comprising a closed conduit containing a liquid which is continuously circulated through the conduit by a pump.  An electrical resist-ance heating unit serves to heat the liquid in the con-duit and heat is transferred from the liquid through a heat exchanger to a medium to be heated.  A proportional timer is operably connected in the electrical circuit with the heating unit.  The timer has a cycle of fixed duration composed of an "on" interval and an "off" interval, with the duration of the "on" interval being variable within the cycle.  A temperature sensor senses the tempera-ture of the liquid in the conduit and if the temperature falls below a set value, the sensor acts to operate the timer and energize the heating unit.  A second tempera-ture sensor acts to adjust the "on" interval of the timing cycle in proportion to the deviation of the liquid temperature from the temperature setting.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to the reduction of polymer buildup on the inner surfaces of a polymeriza-tion reactor by applying a polymer buildup resistant coating to the inner surfaces thereof, the method or process of applying said coating being the subject of this invention.  An approximate monolayer coating on the inner surfaces of the reactor results from applying thereto an aqueous or organic solvent solution of the coating material by means of a hydrocarbon gas, Such as propane, for example.  The coating material is an organic compound or polymer which is capable of re-sisting polymer buildup thereon.  As examples of such coating materials, there may be named the polyaromatic amines, self-condensed polyhydric phenols, tannic acid and tannates, various dyes, such as nigrosine, and the like, etc.  When using vinyl chloride to apply the coating material, the same reaches the inner reactor surface  in the form of a mist.  When polymerizing olefinic monomers, such as vinyl halides, vinylidene halides, and vinylidene monomers having at least one terminal CH2=C? grouping, and mixtures thereof, in the presence of said coating, polymer buildup on the inner surfaces of said reactor is substantially eliminated.

The low intensity ultraviolet radiation used is concentrated on the packaging material and capable of being positioned in close proximity thereto without resulting in heat damage.  Low intensity ultraviolet is less dangerous with respect to the operator and effective shielding may be achieved easily.  This method and apparatus is particularly suited for incorporation into automated packaging apparatuses which use preformed containers and series of interconnected lids for sealing of the containers.  The invention will be of particular benefit to the packaging of dairy products where an extended shelf life is desired.
