Abstract: METHOD OF CONTROLLING PRODUCTION PROCESSES            AND APPARATUS THE THEREFOR    ABSTRACT OF DISCLOSURE          The specification discloses a novel method for controlling pro-duction processes of a pneumatic, electrical or hydraulic nature and appa-ratus therefor. The method, and therefore the apparatus for performing said method, operate on the basis of counteracting any process change by utilizing the difference between a feedback signal related to a current con-dition of the process and a desired value signal related to the desired con-dition of the process, as well as utilizing the rate of change between said feedback signal and said desired value signal.     The error difference and rate of change are then utilized to pro-duce a correction signal which is adapted to remain unchanged as long as the process being controlled, and the desired value signal, both remain in static condition, but which also has a unique look ahead feature such that said correction signal attempts to become saturated as soon as a new desired value is supplied, or a process change occurs. The correction signal, if saturated, is brought out of saturation much faster by using both the rate of change of the actual error difference between said desired value and said feedback signals and the actual error difference between said sig-nals in a manner which is much faster than if only the error difference was used. If said correction signal never does reach a saturation point, or if it is saturated, upon becoming unsaturated, the correction signal is then changed much faster than previously possible by using the rate of change of the error difference rather than the error difference only.     Further changes to the correction signal occur in a manner described in the specification and then the signal is supplied to a driver of the appropriate type to cause the process to arrive at a desired condition.

Abstract: SOLIDS PRECIPITATION PROCESS FOR COAL-DERIVED LIQUIDS              USING RECYCLED SOLVENT FRACTIONS                              ABSTRACT           A solids removal step for coal liquefaction-hydrogenati processes utilizes the addition of a selective solvent liquid fraction to coal-derived liquids to produce rapid precipitation of solids and thereby achieve a high percentage of solids removal from the coal-derived liquids.  It uses a selected solvent additive liquid fraction which is convenient obtained from the coal liquefaction process by distillation, without need for additional hydrogenation steps or the addition of any extraneous liquids.          The solvent liquid used is a coal-derived liquid fraction boiling between about 300-550°F, which has a Watson characterization factor (K) in the range of 9.5-11, and also has a Kauri-butanol value exceeding about 40 and preferably is 50-130.  Following mixing of the two hydrocarbon liquids together, the resulting settling time for particulate solids in the liquid mixture is relatively short, usually less than about 45 minutes and under certain conditions may be about 15-30 minutes.           The resulting clarified overflow liquid portion from this solids precipitation step contains less than about 0.1 W % ash and unconverted coal solids, while the underflow liquid portion contains 30-50 W % solids and may receive further processing as desired, such as coking.  Although this solids precipitation step is useful with various coal liquefaction processes, it is preferably used with catalytic hydrogenation processes such as the H-Coal?  process wherein between about 2 and 4 W % hydrogen is chemically combined with the coal derived liquid.

Abstract: .     Abstract of the Disclosure A progressive resistance excercising machine having a single, substantially vertical guide column adapted to guide a vertically reciprocative carriage provided with a laterally outwardly extending lifting arm engageable by the trainee. The design of the highly compact machine is unique in that the guide column, as well as a weight selector bar which is connected to the carriage, extends through centrally disposed apertures formed in a plurality of weights positioned substantially directly below the carriage.  When the selector bar is selectively inter-connected with one or more weights in the weight stack, a lifting force exerted on the lifting arm will cause the carriage and the selector bar to move upwardly against the urging of the weights.          As the carriage moves upwardly, the central guide column accom-plishes the dual function of uniquely guiding the travel of the carriage as well as constraining the path of travel of the weights thereby eliminating the need for separate guide means for guiding the weights and the carriage.

Abstract: METHOD AND APPARATUS FOR WINDING AND TWISTING YARN             ABSTRACT OF THE DISCLOSURE A method and apparatus for winding and twisting yarn onto a spool directly from an extrusion line or other production source by means of an inline twister. The inline twister comprises the following elements:  a rotatable spindle, a bottom flange securely fastened to the spindle having a catch on the outer periphery, a removable interlocking top flange positioned on the spindle, means for positioning the spool concentrically about the spindle, a twister ring concentrically po-sitioned about the spindle having a slit, and a rotatable traveler positioned on the twister ring having a hook inwardly directed toward the spindle.     The method of winding and twisting the yarn onto a spool comprises guiding the yarn adjacent to the spool. This yarn is then positioned adjacent to the slit in the twister ring and is allowed to pass therein.  The spindle on which the spool is contained is then rotated so that the catch-equipped bottom flange contacts the yarn and holds it tight.  As the yarn is rotated by the bottom flange it contacts the hook equipped rotatable traveler positioned on the twister ring and this combination of rotating flange and traveler provides the means for inserting twist into the yarn as well as wrapping the yarn about the spool.  As the yarn is wound about the spool the twister ring is reciprocated so that the point of collection varies about the spool.

Abstract: LINE ADJUSTMENT APPARATUS FOR A TYPEWRITER                  Abstract of the Disclosure Line end adjustment decisions for a typewriter printing from text storage are based on a set of zones that are defined along the line respective of appearance considerations for the right margin.  The potential end location for each successive word ready for addition to a line is calculated and such end location is compared to the previous word's end location, by reference to the appearance zones, for determin-ing whether or not the word should be assigned to the next line (i.e., whether or not a carrier return is inserted). By so identifying the word end positions that bracket a word with respective corresponding zones, decision logic, based on preferred responses to the various zone combinations presentable by such end points, is enabled, effectively, to impose an overall pattern of preferred line ending decisions to establish a right margin.  For a preferred implementa-tion, the line ending decisions for one or more of the zone combinations are further influenced by the position of the end point of the previous line, which consideration is important to the visual impression produced by the succeed-ing line ending point.
