Abstract: GRAPPLE PIVOT SNUBBER                 Abstract of the Disclosure A grapple assembly includes a grapple suspended from an outer end of the grapple boom by means including a double clevis permit-ting the grapple to swing about a pair of crosswise disposed pivot axes.  A double clevis is pivotally connected to the lower end of an upright output shaft which is rotatably mounted in the grapple boom.  A fluid supply passage is provided in the shaft and has a first pair of outlets disposed diametrically from each other and in a vertical plane containing one of the pivot axes and a first pair of snubber hoses are connected between these outlets and the grapple frame.  Similarly, a second pair of out-lets of the passage are located diametrically from each other and in a vertical plane containing the other pivot axis and a second pair of snubber hoses are connected between these outlets and the frame.  A hydraulic circuit is provided for selectively pressurizing the snubber hoses to thereby stiffen them and in-hibit swinging movement of the frame about the pair of axes.  In a second embodiment of the invention, the fluid supply passage in the output shaft has only a single outlet and it is located on the axis of the shaft and connected between this outlet and a blind bore on the frame is a single snubber hose which inter-sects the pivot axes of the frame.

Abstract: CLUTCH/BRAKE MECHANISM               ABSTRACT OF THE DISCLOSURE: There is disclosed a clutch/brake mechanism of the "disc" type wherein the co-acting friction producing members are of unique sectional configurations; whereby the frictional interaction thereof is initially concentrated adjacent the operating peripheries thereof and progressively advances toward the hub portions thereof as the friction producing members gradually wear.  Thus, the clutch/brake disc members operate at maximum mechanical advantage throughout their useful lives, while at all times also functioning to prevent entrance of external contaminants into the mechanism.

Abstract: A METHOD OF PRODUCING POLYMERIC AQUAGELS AND FILMS, PARTICULARLY OF POLYACRYLONITRILE, AND FILMS PRODUCED                   BY SUCH METHODS         Abstract:            A polymer film consists essentially of a biaxially-oriented high nitrile addition polymer containing at least 80% acrylonitrile repeating units and an impregnant in the form of a low molecular weight non-volatile polyalkylene glycol, preferably triethylene glycol, dispersed in the polymer in a sufficient amount to plasticize the polymer and increase film toughness.  In producing the film, a continuous strip of a polymeric aqualgel having a substantially constant water content is passed through an aqueous bath containing the impregnant so that the impregnant is absorbed into the aquagel.  The impregnant is added to the bath at a rate to maintain a substantially constant concentration of impregnant in the bath and allow concentration of water components in the aquagel and bath to reach equilibrium.

Abstract: ABSTRACT OF THE DISCLOSURE   A tensioner for a power transmission belt that is adapted to be operated in an endless path and a method of making the same are provided herein.  The tensioner includes a support unit adapted to be  fixed relative to the belt.  A belt-engaging unit is carried by the support unit and is movable relative thereto.  A mechanical spring unit is operatively associated with the support unit and the belt-engaging unit for urging the belt-engaging unit relative to the support unit and against the belt with a force to tension the belt.  A fluid dampening unit is operatively associated with the support unit and the belt-engaging unit to dampen movement of the belt-engaging unit relative to support unit in at least one direction of the movement thereof.  That dampening means dampens the movement of said belt engaging means with a greater said restricting force when said belt engaging means is being moved in a direction that is opposed to the force of the spring means and, thus, in a direction away from the belt, than the restricting force of the dampening means when the belt-engaging means is being moved in the opposite direction relative to the support means.

Abstract: Abstract of the Disclosure A vector generator includes a linear charge pump in the form of a DAC with a constant but variable current output that can charge a capacitor connected between the output and one of the input terminals of an operational amplifier.  A second constant current generator having an output current one-half that of the maximum output current of the DAC and of opposite polarity also is provided for charging the capacitor, the constant current generators being so connected to the capacitor that it can be charged either positively or negatively.  A switching network controls whether the capacitor is charging or not depending on the state of the switching network.  A second DAC with a constant but variable output voltage is provided and produces an output indicative of the coordinate of the vector to be drawn.  The voltage on the capacitor is compared to the output voltage of the second DAC, and, when they are equal, a control signal is produced that changes the state of the switch to terminate charging of the capacitor.

Abstract: ABSTRACT Alkylated aromatic compounds, either alone or in a mixture with an alkylating agent, are disproportionated, alkylated or transalkylated in the presence of a ZSM-22 zeolite.  The products of the reactions contain amounts of the para-isomer which are in excess of the equilibrium amounts of such isomer.  The ZSM-22 zeolite is a crystalline zeolite material having an X-ray diffraction pattern as set forth in Table I of the specification.         Alternatively, mixtures of 1,2-disubstituted and/or 1,3-disubstituted isomers along with the 1,4-disubstituted isomer of an aromatic compound can be contacted with the ZSM-22 zeolite under cracking conditions to thereby selectively crack the 1,4-disubstituted isomer and reduce the proportion of the 1,4-disubstituted isomer in the isomer mixture.

Abstract: ABSTRACT     Transferring mastership in a multi-master communica-tions channel of a system having a plurality of intercommunica-ting stations is accomplished by a method which includes the grouping into a logical loop of high traffic stations those stations which must be serviced frequently, and the grouping into at least one other logical loop of low traffic stations those requiring less frequent service.  The token signifying mastership is passed from station to station in the high traffic loop at a maximum speed compatible with the work to be done by each station until a predetermined time period has lapsed since the mastership was passed through the low traffic group.  Upon expiration of that time period, mastership is passed sequentially through the low traffic loop stations.          Mastership is then returned to a previously determined high traffic loop station.
