Abstract: Abstract of the Disclosure A process for the production of vinyltol-uene, comprising the steps of:  producing a crude vinyltoluene product by the catalytic dehydrogenation of ethyltoluene; removing compounds from the crude vinyltoluene product which have a higher molecular weight than vinyltoluene to form a prepurified crude vinyltoluene product; and fractionally distilling the prepurified crude vinyltoluene product in a distilla-tion apparatus to recover purified vinyltoluene.  The higher molecular weight compounds removed are compounds which foster the conversion of vinyltoluene into cross-linked polymer.  The compounds removed preferably have more than 11 carbon atoms.  In one embodiment, the step of removing higher molecular weight compounds comprises condensing a vaporous crude vinyltoluene product to form a crude vinyltoluene solution, and subjecting the crude vinyltoluene solution to flash distillation to form a vaporous prepurified crude vinyltoluene product.  Optionally, the prepurified rude vinyltoluene in the distillation apparatus may include a polymerization inhibitor.

Abstract: ABSTRACT OF THE DISCLOSURE       In a system for recording or playing back a television signal, composed of a picture carrier which is FM modulated with a video signal and an audio carrier which is modulated with an LF audio signal, recorded along oblique tracks on a magnetic tape, the system including two playback heads which alternately scan successive tracks, a keying pulse is generated in time coincidence with each moment when scanning switches from one head to the other.  The keying pulse can be used during playback to increase the gain of an amplifier conducting the audio carrier to an extent to cause the amplifier to generate output oscillations at a selected frequency.  Alternatively, the keying pulse can be used during recording to temporarily increase the amplitude of the audio carrier.

Abstract: ABSTRACT     A double-seal, molded plastic screw cap for use with a solid cosmetic product, consisting of a resil-ient, cup-shaped plastic cap body having internal screw threads, the bottom rim of the body being engageable with an external shoulder of the container to effect a seal therewith.  Above the screw threads, the side wall of the body has an inwardly raised, annular sealing bead adapted to slidingly and telescopically engage an outer annular surface of the container neck at the top rim thereof, to effect a second seal.  A clearance chamber exists above the sealing bead, into which a portion of the cosmetic product can extend.  The clearance chamber is characterized by thin walls, to effect a saving of plastic material.  The sealing bead is effective indepen-dent of the exact axial positioning of the cap, and the bottom rim seal of the cap requires that the latter be tightly screwed onto the container.  The advantage of the present construction over the devices of the prior art is that an improved seal is effected, while at the same time the overall manufacturing cost is reduced by the maximum extent possible.

Abstract: TRIM CONTROL FOR PARTIAL OXIDATION GAS GENERATOR                   (D#73,824-F) ABSTRACT         Trim control of a partial oxidation gas generator for the production of synthesis gas, reducing gas, or fuel gas is effected by two improved control schemes which are automatically operated separately or in sequence.  The control systems include sensors sensing the flow rate of the feedstreams and analyzers which provide signals corresponding to the wt.% carbon in the effluent gas quench cooling and scrubbing water for use in controlling the particulate carbon in the effluent gas stream, and/or signals corresponding to the mole fraction of CH4 (dry basis) in the cooled and cleaned effluent gas stream for use in controlling the temperature in the reaction zone.  The signals from the sensors and analyzers are provided to the system control unit which computes values that represent the relative difference between the actual and desired carbon-make and/or the actual temperature in the reaction zone, and the relative difference between the actual and desired temperature in the reaction zone.  The actual temperature is determined as a function of the methane concentration.  These values are automatically compared with set point values and when adjustments are necessary, signals from the system control unit are provided to a flow rate regulating means which adjusts the flow rate of the free-oxygen containing gas by a small determined amount for control of the particulate carbon and/or to a flow rate regulating means which adjusts the flow rate of the temperature moderator by a small determined amount for control of the temperature in the reaction zone. When the computed adjustment for either stream requires increasing or decreasing the flow rate greater than by a specified amount then no adjustment is made to the flow rate controller but a high or low level alarm is actuated to alert the plant operator.     - I -

Abstract: FLAT BOTTOM HOLE DRILL            ABSTRACT OF THE DISCLOSURE        A drill is provided having opposed primary and secondary cutting edges extending perpendicular to the longitudinal axis of the drill.  The primary cutting edge extends across the longitudinal axis of the drill to a terminus intermediate the longitudinal axis and the periphery of the drill.  The secondary cutting edge extends inwardly from the periphery of the drill to a point intermediate the periphery of the longitudinal axis of the drill.  The primary and secondary cutting edges are spaced from one another along the longitudinal axis so that the primary cutting edge leads the secondary cutting edge during a drilling operation.  The primary cutting edge drills the inner part of the hole and the secondary cutting edge drills the outer part of the hole.          The primary and secondary cutting edges are designed to generate substantially balanced forces about the longi-tudinal axis of the drill.  Flutes extend from each cutting edge for efficient and reliable removal of chips.
