Abstract: ABSTRACT OF THE DISCLOSURE      The invention relates to the manufacture of gasoline and concurrent production of chemical grade aromatic compounds of eight or less carbon atoms by catalytic reforming of naphtha and using part of the reformate for each purpose.  A novel sequence is described resulting in higher quality gasoline of lower "heavy end" content, which comprises fractionating a catalytic reformate to provide a light reformate containing most of the C8 and lighter components of the reformate and a heavy reformate which contains no more than 20 weight percent of xylenes, blending said light reformate with other motor fuel components to provide a finished gasoline, contacting said heavy reformate with a catalyst characterized by an effective amount of type ZSM-5 zeolite, zeolite ZSM-12 or zeolite ZSM-21 at about 550 to 1000°F., about 100 to about 2000 pounds per square inch, admixed with 0.5 to 10 mols of hydrogen per mol of hydrocarbon and at a weight hourly space velocity between about 0.1 and about 200 unit weights of hydrocarbon per unit weight of said zeolite in the catalyst per hour, and recovering at least one aromatic compound of eight or less carbon atoms from the product of contacting said heavy reformate with said catalyst.

Abstract: ABSTRACT     A process for producing fine structures on a base such as a semicon-ductor device having electrode structures or a conductor path structures char-acterized by providing a base having a surface which is either etchable or is provided with an auxiliary etchable layer, providing a mask on the surface, which mask has openings complementary to the fine structure of material to be applied on the surface, providing an etching agent which attacks the surfaces of the base without attacking the mask, etching the uncovered portions of the base until an under-etching of predetermined width exists beneath the edges of the mask, depositing the layer of material on the entire surface, control-ling the amount of depositing so the layer of material being deposited on the mask and on the etched surfaces of the base are not in contact with each other, and subsequently removing the mask with the layer of material deposited there-on.  If an auxiliary layer is on the surface it may be subsequently removed by etching without substantially etching the deposited fine structure or it may be retained to provide closely spaced electrode patterns.  If the auxiliary layer is to be removed, it is of a material such as a metal alloy that can be selectively etched without damage to the material or metal deposited as the fine structure.

Abstract: ABSTRACT           An improved controller assembly is utilized in a hydrostatic steering system having an engine driven pump with a servomotor which is effective to vary the displacement of the pump upon operation of a pressure responsive valve assembly.          The controller assembly includes a housing having a valve chamber with an inlet port which receives fluid from the pump.  Upon rotation of a steering wheel, a controller valve member is moved to an actuated position and a metered flow of fluid is conducted from the valve chamber through a motor port to a steering motor.          In addition, fluid is conducted from the steering motor through another motor port to the controller valve chamber.  The fluid from the steering motor is then discharged from the valve cham-ber to reservoir or drain through an outlet port.  The controller assembly also includes a control port connected in fluid communi-cation with the pressure-responsive valve assembly.  Surfaces on the controller valve member and housing cooperate to form an ori-fice which causes the fluid pressure conducted to the control port to vary as a function of variations in the rate at which the steering wheel is rotated, and in addition to the pressure required to overcome any variable steered load.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to polymeric coating compositions which are at least partially soluble in water and are particularly stable.         Polyester, polyesterimides, polyesteramides, polyesteramideimides, polyesterhydantoins and polyester urethanes are prepared with free carboxyl or carboxylic acid groups.   The carboxylic acid groups are neutralized with amine containing material, at least fifty percent excess amine being used, producing a coating composition which is at least partially soluble in water.   The coating compositions are particularly useful as electric insulating coatings or other  enamels which are readily coated on a metallic or other substrate and when cured form coatings having good electrical and physical properties.   They are also useful in making laminates, composites, and the like.

Abstract: Abstract of the Disclosure A system for instruction in the manipulation of the chord portion of a keyboard of a musical instrument in 3-4 or 4-4 time includes uniquely written music which provides a student with an identity of the root note of each chord to be played and the timing (but not necessarily the identity) of the corresponding chord triad to follow the root note. In conjunction with the music, an apparatus senses the depression of the root note key by the student, provides a sustained confirming identification of that note, and provides the identity (but not the timing) of the triad notes.  The indication is retained until a different note key is depressed.  The apparatus is useful independently of the written music or keyboard instrument to demonstrate the 5-2-1 system of fingering chords as set forth in U.S. Patent No. 3,335,630, issued August 15, 1967 to Arthur R. Schmoyer.  The applicability of the apparatus as a visual aid to instruction is particularly vivid as one successfully activates the apparatus through a scale of triads.  This activation can be done on a keyboard, indepen-dently of the keyboard by simply manually manipulating actuators, or could be accomplished on a classroom scale by a display including other actuators such as conventional switches or push-buttons of conventional forms which may be remote from the display itself.

Abstract: CRYSTAL OSCILLATOR TEMPERATURE                    COMPENSATING CIRCUIT                         ABSTRACT      A circuit for generating a temperature varying control voltage which is applied to a varactor diode to temperature compensate a crystal oscillator is disclosed.  The circuit produces a substantially linear voltage versus temperature variation, including a point of inflection, in a middle temperature range, and a substantially non-linear voltage versus temperature variation in hot and cold temperature ranges.  The control voltage versus temperature character-istic also undergoes a change in slope polarity in both the hot and cold temperature ranges.  The temperature compen-sating circuit has a middle range circuit for independently creating the substantially linear variation in the middle temperature range, a cold range circuit operative below a predetermined temperature for creating the desired variation in the cold temperature range, and a hot temperature circuit operative above a predetermined temperature for creating the desired temperature variation in the hot temperature range.  Each temperature range circuit includes a thermistor and a transistor which together control the operative range and the magnitude of the temperature variation contributed by each of the circuits.

The pin is driven firstly through the tag, secondly through the merchandise, thirdly through the merchandise again, fourthly through the tag again, and fifthly through the tag again, and thereupon the movable pin guiding and pin crimping member is moved again to crimp the pin.  A bottom tag in a stack is separated by feeding it toward the pinning zone in one machine cycle and the separated tag is positioned between the anvil and the plunger during the early part of the next machine cycle.  The tag feeding device for separating the bottom tag and the tag feeding device for positioning the separated tag at the pinning zone move relative to each other during the pinning cycle.
