Abstract: ABSTRACT OF THE DISCLOSURE           Raw petroleum coke or other carbonaceous matter containing a relatively large proportion of volatile matter is calcined in a rotary kiln in an oxygen-enriched atmosphere. The enriched atmosphere permits the oxidation of the hydro-carbon gases driven off as volatile matter during calcina-tion to supply the total endothermic heat needed for vola-tilization of the lower molecular weight components and modification of the coke structure, thus enabling operation without the use of externally supplied fuel heat.  Other advantages include greater uniformity of the temperature of the calcining coke bed, reduction of air pollution through lessening of hydrocarbon and particulate emissions, a de-crease in the total volume of emissions, and improved de-sulfurization of the coke.

Abstract: APPARATUS AND METHOD FOR MAKING DYNAMOELECTRIC       MACHINE WINDINGS ABSTRACT OF THE DISCLOSURE Methods and apparatus are disclosed for producing dynamoelectric machine coil groups or winding poles.  A clamp device, relatively axially movable coil form and turn receiver, and relatively rotatable flyer are used, and interpole wire segments are established by intercepting, at a fixed location, a segment of wire extending between the form and flyer prior to complete cessation of relative rotation between the same.  Subsequently, the form and receiver move relative to one another, to assure that all of the turns of a first pole are disposed in the receiver. While assurance is being attained that all of the turns of the first pole are disposed within the receiver means, and while the segment continues to be intercepted, the interpole wire segment is positioned in a fixed clamp means in the event that it has not been previously so positioned. The interpole wire segment is accurately located relative to the clamp because of the interception of the segment of wire at the fixed location regardless of the final stopping position of the wire dispensing means.           Intercoil winding segments are also accurately established.  For example, an intercoil winding segment is deflected out of the winding plane and in a direction toward a subsequent winding form stage during the development of the last turn of a coil developed on the previous winding stage.  Deflection of the intercoil winding segment is preferably accomplished substantially concurrently with advancement of the winding form relative to the turn receiver.  In one form, an inclined ramp is moved into the winding plane and into interfering relation with an intercoil winding segment as the winding segment is being developed and as a subsequent winding stage is being moved into the winding plane.

Abstract: ABSTRACT           An alkali metal or alkaline earth metal salt of an aromatic or cycloaliphatic dicarboxylic acid such as the disodium or dipotassium salt of terephthalic or isophthalic acid is reacted with phosgene in an inert organic solvent in the presence of a tertiary nitrogen compound such as pyridine.   The solid alkali metal or alkaline earth metal chloride salts which are by-products are easily separated from the organic solu-tion containing the product acid chloride.  The solution is then, in some form, interfacially reacted with a bisphenol such as bisphenol A.   Excess phosgene in the diacid chloride synthesis can be carried over to the polymerization if a poly(ester carbonate) is to be produced or removed if a polyester is to be produced.          Certain low levels of a tertiary nitrogen compound with a pyridine nucleus in the organic solution do not interfere with the interfacial polymerization.

Abstract: ABSTRACT            SYSTEM FOR DRIVING A GAS DISCHARGE DISPLAY        An improved system for driving a gas discharge display which prevents streamers of ionized gas from forming between adjacent character positions.  Each of a plurality of character positions has an anode driver to which anode drive signals are sequentially applied.  All odd character positions share a first cathode decoder/driver and all even character positions share a second cathode decoder/driver. Cathode drive signals are simultaneously applied to the first and second decoder/driver circuits.  A first logic device, responsive to all odd position anode drive signals, outputs a blanking signal which is applied to the blanking input of the even character cathode decoder/driver to bias all even character cathodes into a non-conducting state whenever an anode drive signal is applied to an odd character anode.  A second logic device, responsive to all even position anode drive signals, outputs a blanking signal which is applied to the blanking input of the odd character cathode decoder/ driver to bias all odd character cathodes into a non-conducting state whenever an anode drive signal is applied to an even character anode.  Thus, when a particular character position is scanned by the anode drive signals and the selected cathode segments thereof are energized, the cathodes of adjacent character positions are biased into a non-conducting state making it impossible for streamers of ionized gas to form between the energized character and its neighbors.
