Abstract: IMPROVED DRIVE MECHANISM FOR DOUGH SHAPING                  APPARATUS                     Abstract of the Disclosure A mechanism for controllably driving a plunger in a dough forming apparatus of the type that has a chamber in which the plunger resides to move dough in incremental steps toward one end of the chamber.  Spanning the one end of the chamber is a plural-ity of parallely spaced apart elongate members, the spacing between the elongate members corresponding to the thickness of a french fry shaped piece, e.g. 1/4 inch.  The plunger is advanced by incre-ments of a similar distance, the distance corresponding to the width of the french fry piece and when a plurality of dough bodies protrude through the spaces between the elongate members a single wire cutter is reciprocated across the exterior of the elongate members to sever the protruding bodies thus to form french fry shaped pieces.  In order that the pieces possess a square or sub-stantially square cross sectional shape, the mechanism of the invention assures accurate incremental advancement of the plunger as well as affording a quiescent period during which the wire cutter is reciprocated  across a transverse plane exterior with the surface of the elongate members.  An extremely simple and accurate drive mechanism for assuring constant incremental advance-ment.  A mechanism which in addition to affording constant incre-mental advance of the plunger provides a quiescent period for transverse dough cutting and affords actuation of the dough cutter during such quiescent period in response to a single driving stroke applied to the mechanism.

Abstract: ABSTRACT      A cellulosic pulp and bleaching process is described. The process integrates two cycles, one is a digestor liquor cycle and the other is a sulfur cycle, The digestor liquor cycle comprises the steps of digesting a fibrous cellulosic feed to form a pulp, separating the pulp and bleaching it in at least one stage with chlorine dioxide, evaporating and burning the remaining waste liquor to form a smelt, dissolving the smelt to form a green liquor and utilizing the green liquor, after  as at least a portion of the feed stock for the digestor step.    The sulfur cycle of the present invention utilizes a portion of the green liquor of the digestor liquor cycle.  The green liquor is carbonated to form a bicarbonate which is then stripped of H2S.  The H2S is converted into H2SO4 and utilized as a feed stock to a chlorine dioxide generator. The chlorine dioxide generator utilizes H2SO4 as feed stock and produces Na2SO4 as a by-product. The Na2SO4 by-product from the chlorine dioxide generator is furnaced in common with the evaporated waste pulping liquor from the digestor liquor cycle to form a common smelt, which is dissolved to form a green liquor, a portion of which is used in the sulfur cycle and a portion of which is used in the digestor cycle.

Abstract: ABSTRACT OF THE DISCLOSURE         An in-line voltage balancing circuit sums a trim voltage with each phase voltage of a polyphase generating system to assure that the voltage between each phase and neutral is equal to the average voltage of all the phases.  An individual error signal representative of the difference between each phase voltage and the average voltage is pro-vided to individual phase modulator circuits.  The phase modulator circuits develop pulse width modulated signals wherein the pulse width is proportional to the amplitude of the error signal.  The outputs of the phase modulator circuits are connected to switching amplifiers which provide trim voltages proportional to the phase modulated signals.         Summing transformers are employed to sum the individual trim voltage with appropriate phase voltage so that the voltage for each phase equals the average voltage.

Abstract: ABSTRACT           The present invention relates to raise-type earth boring drills,  and more particularly to such raise drills in which the drive stem is removably attached to the raise bit body.  A relatively large diameter hole may be provided between two locations in a mine by an operation commonly referred to as raise drilling.  If the drive stem is removable, the elements of the drills having a relatively short lifespan can be replaced, thereby extending the useful life of the bit.  Various problems have been encountered in utilizing prior art raise bits having removable stems.  Quite often, special torquing tools are required to disassemble and remove the drive stem from the raise bit body.  Additionally, the torsional forces are often trans-mitted through conical or circular collars which are less positive than desired, and the devices do not provide for proper alignment of the stem attachement.  The present invention obviates the above-mentioned shortcomings by providing a novel attachment In which the bit body is detachably secured to a drive stem extending through a central opening in the raise bit body and including a plurality of tapered flat surfaces located about the periphery of the bottom end thereof.  A plurality of bolted wedge blocks, attachable to the main bit body may be provided to engage the tapered flat surfaces of the drive stem in order to urge the shoulder of the drive stem into locking engagement with the main bit body.
