Abstract: ABSTRACT      PRODUCING SOLVENT-GRADE METHYL-NAPHTHALENE         A methylnaphthalene-containing coal tar dis-tillation fraction which has already been extracted with base to remove tar acids is treated by three ex-tractions to remove tar bases and impurities which have or form color or odor.  No final distillation is required.  The first extraction is with about 70-85% sulfuric acid, the second with about 90-100% sulfuric acid and the third with aqueous base such as about 2-25% sodium hydroxide.  The resultant methyl-naphthalene is suitable for dye-carrier and other solvent applications.

Abstract: Title of the Invention POLYMERIZATION PROCESS Abstract of the Disclosure In a process for polymerizing a monomer capable of being formed, upon polymerization, into a solution having an upper cloud point of the corresponding polymer in a reaction medium being liquid under the reaction conditions, the polymerization being carried out under such conditions that the resulting polymer dissolves in the reaction medium; the improvement wherein (i) the polymerization is carried out in a polymerization zone at a temperature above the upper cloud point of said polymer solution and under conditions which enable the polymer solution to be separated into two phases, (ii) the polymerization is carried out under stirring conditions which maintain the two phases under said phase-separating conditions in a dispersed and mixed state, and (iii) the resulting polymer solution is sent to a separating zone located independently of said polymer-ization zone, thereby separating it into two phases in the separating zone at a temperature above the upper cloud point, and thereafter, the polymer-rich liquid phase as a lower layer is recovered while the polymer-lean liquid phase as an upper layer is recycled to the polymerization zone.

Abstract: TELEPHONE LINES STATUS SENSOR          Abstract of the Disclosure A lines status sensor provides for monitoring of the operating status of one or more telephone lines at an associated telephone station apparatus.  The lines status sensor includes a translation circuit being responsive to potential differences appearing across the telephone line, for generating a voltage signal of corresponding polarity in relation to a reference voltage.  A voltage divider circuit provides the reference voltage in addition to a first limit voltage being of a more negative potential than the reference voltage, and a second limit voltage being more positive than the reference voltage.  A detection circuit is responsive to the first and second limit voltages such that when the potential of the output voltage from the translation circuit is within a range as defined by the first and second limit voltages, an output signal of the detection circuit is of one binary state thereby indicating an OFF    HOOK status of the telephone line, and when the potential is outside of the range the output signal is of another binary state thereby indicating an ON HOOK status of the telephone line.  In a variation of the line status sensor a wider range is useful for detecting the presence of ringing signals on the telephone line.

Abstract: ABSTRACT OF THE DISCLOSURE         Drying of tobacco particles in heated rotary drum drier is improved by flowing air through the drum at a flow rate which imparts translational or linear motion  to  the  particles. The  translational  motion causes the particles to become classified based on size and weight and thereby to cause smaller particles to pass through the drum at a faster rate than larger particles.   In this way,  smaller particles are  less exposed to the drying heat than larger ones,  so that overdrying of small particles is avoided and overall filling power is improved.

Abstract: VIDEO IMAGE SIZE SCALING                       Abstract of the Disclosure The size of an object in the field of view of a television camera or other device which can create an image of an object is determined by generating a calibrated grid for a video display in response to a measurement of the distance between the image creating device and the object itself.  Both the object and the grid may be displayed on a video display means in such a manner that the object is overlaid with the calibrated grid.  The length of the lines in the calibrated grid or the distance between points in the calibrated grid, as actually displayed, will be representative of a particular distance and thus an observer viewing the video display can determine the actual size of the object by using the calibrated grid to actually measure the object .

Abstract: A B S T R A C T     The invention relates to a process for removing sufficient water from H2O ethanol at least 160 proof to produce ethanol having a proof of 195 or more and it comprises the steps of heating the ethanol water mixture until it is a vapor with sufficient superheat to pass through a dessicant bed of molecular sieves without condensing, and then passing the superheated ethanol water mixture through the bed to remove sufficient water to increase the proof of the ethanol to at least 195.  A portion of the dehydrated ethanol is passed through a second dessicant bed of molecular sieves at less than atmospheric pressure to  desorb the water and ethanol on the dessicant from a previous dehydration cycle, and the flow is reversed through the two beds after the temperature of the bed increases between 11°-14°C (20°-25°F).

Abstract: ELECTROMAGNETIC UNIT FUEL INJECTOR       WITH CARTRIDGE TYPE SOLENOID ACTUATED VALVE Abstract of the Disclosure An electromagnetic unit fuel injector for use in a diesel engine includes a housing with a pump therein defined by an externally actuated plunger reciprocable in a bushing and defining there-with a pump chamber open at one end for the discharge of fuel to a spring biased, pressure actuated fuel injection nozzle.  The pump chamber is also connected to a first chamber via a solenoid actuated, normally open, hollow pressure balanced poppet valve controlled passage to permit the ingress and egress of fuel.  The first chamber adjacent to one end of the valve is in flow communication with a second chamber at the opposite end of the valve and these chambers are connected to a drain passage and supply passage, respectively.  During a pump stroke, the solenoid can be energized to move the valve in position to block flow from the pump chamber to the first chamber so as to allow the pressurization of fuel by the pump to effect discharge of fuel from the injection nozzle. In a preferred embodiment the solenoid actuated poppet valve is a cartridge type assembly which is adapted to be received in a suitable socket provided for it in the housing and to be secured therein in hydraulic sealed relationship.

Thus, the estimative value is caused to quickly follow up the fluctuation of the demand or the service condition value, and the responsiveness of the cages to the new demand or service condition value can be improved.
