Abstract: DIGITAL FILTER CIRCUIT            Abstract of the Disclosure In the prior art, limit cycle noise is reduced in a second order recursive digital filter by a circuit which randomly inhibits the rounding signal in one of the digital multipliers disposed in the filter.     In the present disclosure, random inhibiting is con-strained to instances in which limit cycle noise is reduced, by monitoring, with suitable logic circuitry, the signals present in the various feedback loops of the filter.          Generally, it has been found that the inhibiting circuit should be allowed to operate only if D1 and D2 satisfy pre-determined magnitude and polarity relationships, where D1? a version of the filter output signal Y(n) that is removed in time by one sample interval, and D2 ? a version of the filter output signal Y(n) that is removed in time by two sample intervals.  The result is the avoidance of larger transients.

Abstract: ABSTRACT            A dashpot assembly having a single annular diaphragm the inner periphery of which forms a valve movable relative to a metering passage between chambers formed at opposite sides of a plunger assembly in the dashpot.  Upon movement in one direc-tion the valve element requires air to pass through the meter-ing passage and upon movement in the opposite direction the valve moves out of engagement to permit free flow between op-posite sides of the plunger.  The dashpot incorporates a ring element which serves to maintain the metering passage free of obstructions and dirt and which extends the effective area of the diaphragm.

Abstract: ABSTRACT OF THE DISCLOSURE    In the representative embodiment of the new and improved apparatus disclosed herein, a so-called "stuck-point indicator" or "freepoint-indicaztor" tool includes a deformation-responsive sensor tande?ly supported between upper and lower selectively-operated tool anchors of a unique arrangement which, in the preferred embodiment of the tool, are cooperatively arranged to be sequentially engaged with longitudinally-spaced wall portions of a string of well pipe believed to be stuck in a well bore.  In the disclosed embodiment of the tool, each tool anchor respectively includes a set of pivoted anchor members and actuating links adapted to swing the anchor members outwardly into anchoring engagment with the pipe wall for securing the tool against longitudinal movement in the pipe string.  To further secure or stabilize the tool against wobbling or angular movement in the pipe string, the pivoted actuating links are cooperatively arranged to become wedged against the opposed side walls of elongated grooves on the tool body as the anchor members engage the pipe wall.

Abstract: ABSTRACT  OF  THE  DISCLOSURE     An improved slitter for making plural fabric openings, while the fabric is being knitted on a rotary knitting machine.  At least one electric resistance heated wire is operatively mounted on a rotary yarn trimmer associated with the rotary knitting machine, the wire being rotatable with the yarn trimmer.  The wire is brought into periodic momentary contact with a fabric tube being knit by the knitting machine to form at least one slit in the fabric tube generally parallel to the axis of the fabric tube.          The heated wire is brought into engagement with the fabric tube by a cam arrangement for effecting selective generally radial movement of the wire with respect to the rotatable member during rotation of the wire.  A stationary element may be mounted on the knitting machine for cooperating with the wire to effect cutting.  This element is mounted on the inside sinker ring which is part of the knitting cylinder and is synchronized for rotary movement with the trimmer and slide assembly.

Abstract: IMPROVEMENT IN FLUXLESS BRAZE PROCESSING OF ALUMINUM                   ABSTRACT OF THE DISCLOSURE         A method of fluxless brazing of aluminum parts is disclosed.  Gaseous species, such as O2 and H2O, which inhibit wetting are controlled by rapid heating (at least 100°C/min) through a critical temperature range (such as 400-590°C) during heat-up to brazing temperatures.  The formation of porosity through the oxide film and the collection of a promoter and wetting agent at the interface with the oxide film will thus occur simultaneously precluding disruption of wetting action by gaseous O2 or H2O.  Wicking of the wetting agent through the film porosity in the critical temperature range will then take place because of the limited time avail-able for the reaction of gaseous O2 and H2O with the film to form a duplex oxide.  Heating may be carried out in a vacuum of 10-3 Torr or less or in an inert atmosphere with pulsed heating, provided the critical heating rate is observed in said critical temperature range.

Abstract: ABSTRACT     A process is disclosed for treating cellulosic mater-ials and obtaining glucose therefrom, which process can include recovering of cellulose from cellulosic materials.  Cellulose is recovered by treating the cellulosic materials to remove hemicellulose, then dis-solving the cellulosic materials in solvent, after which lignin is removed and the cellulose is then pre-cipitated from the remaining solution.  The cellulose may be recovered in sheets or in long threads, fibers or as a flocculent material, and may then be hydrolyzed to provide glucose by subjecting the cellulose to a acid.  A yield of glucose may also be obtained by hydrolyzing the cellulose materials that have been dis-solved in a solvent and then separating lignin from the glucose.
