Abstract: SPROCKET MEMBER CONFIGURATION     ABSTRACT OF THE DISCLOSURE            An improved sprocket configuration for use in a track-type vehicle drive.  The tooth configuration and tooth pocket configuration accommodate packing of the pocket and permit limited displacement of the chain without excessive wear of the chain bushings.  The pocket configuration is relatively deep so as to permit a preselected amount of packing in the pocket root to minimize the chain bushing displacement.  The improved tooth configuration provides a rounded topping surface avoiding bushing wear as may occur with sharp corner tooth configurations of the prior art.

Abstract: Astract of the Disclosure An article which comprises a hollow, radially recoverable member having at least one open end and held in a radially extended condition by a second member outside the recoverable member, by means of a bond between the outer surface of the recoverable member and the inner surface of the second member.  In a preferred article, both members are sleeves.  The bond is capable of being sufficiently weakened by the application of solvent thereto to allow the recoverable member to pull away from the second member and shrink radially.  The second member preferably has apertures to allow radial access of the solvent to the bond and, moreover, is preferably frangible.  It may comprise a plastics or metallic material having weakened portions to enable it to be removed from about the recoverable member after the latter has pulled away.  The article is useful for protecting other articles and, may, when it is of an electrical insulating material, act as an insulator.

Abstract: METHOD OF AND APPARATUS FOR TUNING AN AFT-CONTROLLED   CHANNEL SELECTED APPARATUS TO A DESIRED FREQUENCY                 ABSTRACT OF THE DISCLOSURE      A method of and apparatus for tuning an AFT-controlled channel selecting apparatus of the type having a storage device for storing digital representations corresponding to predetermined channel frequencies from which a selected representation is read out and converted to a control voltage which is applied to a controllable tuning element included in an electronic tuner. When the control voltage is applied, generally it experiences a gradual increase in magnitude until its predetermined control voltage level is attained.  The automatic fine tuning (AFT) circuit may pull in a frequency corresponding to the instantaneous level of the control voltage during the gradual increase in magnitude thereof.  To avoid tuning the electronic tuner to such an unwanted pulled-in frequency, the AFT operation is carried out at a rela-tively slow rate when the tuning of the tuner approaches the frequency corresponding to the read out representation and then at a relatively fast rate when the tuner is tuned to a frequency that deviates from the desired frequency within a predetermined range.     -i-

Abstract: BUFFER CHAINING            ABSTRACT OF THE DISCLOSURE In a data processing system allocation of excessive main/working storage space to sequential input records (input blocks) of indeterminate length frequently results in wasteful fragmentation.  This is avoided by the present invention.  An input-output channel of conventional construc-tion is modified so that in chaining mode it (the channel) can operate optionally to:  1) transfer sequential input data blocks of unspecified length into contiguous positions in main storage, and 2) without CPU interruption/intervention store delimiting information, in storage locations contain-ing Channel Command Words (CCW's) designating respective transfers, which effectively distinguishes storage bound-aries between adjacent blocks.  The storage of delimiting information effectively relieves the control and application programs of the central system of responsibility for analyzing the information context of the data in each block for "possibly obscure" delimiting intelligence.  The foregoing routing and delimiting operations may be made entirely transparent to the peripheral attachment interface of the channel so that peripheral attachment is not complicated.

Abstract: ABSTRACT OF THE DISCLOSURE          A  floating cushion sub for connection to the rotary power head of a drill rig has a mandrel section connectable to a drill string and an outer housing section connectable to the power head.  The mandrel and the housing have mating, axi-ally extending splines permitting relative axial movement while also transmitting torque from the power head to the mandrel.          Mandrel axial movement is limited by a cap member and by an internal shoulder in the housing.  A resilient cushion adjacent the shoulder dampens vibrations when the mandrel and housing are compressed together and a similar cushion adjacent the cap member dampens vibrations when the mandrel and housing are at full extension.  The axial movement of the mandrel relative to the housing improves the function of making or breaking the threaded connections with the drill string by permitting proper coordination of the mating thread pitches and reduces the chance of cross-threading.

Abstract: ABSTRACT OF THE DISCLOSURE A method is provided for leaching comminuted nickeliferous sulfide matte containing by weight about 20% to 75% nickel, about 5% to 50% copper, non-stoichiometric sulfur in the range of over 4% to about 24%, over 0.5% to about 20% iron, the sum of the nickel, copper and sulfur contents being at least about 80% of the matte composition, with the balance gangue or slag and incidental impurities.            Nickel is selectively leached from the comminuted matte using sulfuric acid or spent copper electrolyte solution at substantially atmospheric pressure while vigorously aerating the solution, wherein the pH is raised sufficiently to produce a nickel solution with an iron content of less than about 10 ppm and a copper content of over 5 ppm, the copper being thereafter selectively removed from the nickel solution by passing the solution through an ion-exchange resin selective to the absorption of copper.  Copper eluted from the ion-exchange bed is electro-lytically formed into starter sheets.  The sulfite residue from the atmospheric leach is then formed into a copper-containing electrolyte which is subjected to electrowinning.
