Abstract: AIRBRUSH                ABSTRACT OF THE DISCLOSURE           The disclosed airbrush has an elongated body formed in one piece, as by a molding from plastics material, having an internal cylindrical bore defining a cavity in which other elements are contained.  A carrier member assembled within and sealed for a portion of its length to the cylindrical bore supports the point of a needle at a predetermined distance from the forward end of the body and has an internal passageway for the paint.  The cylindrical bore is closed at its forward end by a cap threadably attached to the body, inside which is threadably secured a jet through which the point of the needle extends.  The carrier member is shaped to provide, in association with the internal bore of the body, a passage for air to the cap and jet region of the airbrush.          Adjustment of the longitudinal position of the cap on the body moves the jet with respect to the stationary needle to provide regulation of the amount of paint flow.

Abstract: ABSTRACT OF THE DISCLOSURE          This specification relates to the electroplating of metals and in particular to an electroplating bath having an acolyte separated from the catholyte by a cation exchange membrane.  This specification provides an electroplating bath having an anolyte separated from a catholyte by a perfluorinated cation exchange membrane.  One use of the present invention is in trivalent chromium plating solutions wherein oxidation of Cr(III) ions to Cr(VI) occurs at the anode and accumulation of Cr(VI) ions in the plating solution ultimately results in the cessation of plating.  The use of perfluorinated cation exchange membranes prevents this anode reaction, with negligible increase in the plating voltage.  The anolyte preferably has a depolarising species therein capable of reducing the electrode potential of the anode when the bath is in use.  In addition the pH of the catholyte can be stabilised by arranging the pH of the anolyte to allow hydrogen transport through the membrane to compensate for hydrogen evolution at the cathode.

Abstract: Abstract of the Disclosure A motor for use in mining machines comprises a ro-tor and a stator disposed around the rotor.  The rotor inclu-des a core comprising conductor bars extending parallel to an axis of rotation of the rotor.  The stator includes windings, the ends of which overlie ends of the conductor bars.  A housing surrounds the rotor and stator to isolate the rotor and stator from volatile mine atmosphere.  The housing inclu-des a first passage for conducting a cooling medium, and a second passage for circulating air within a chamber bordered by the housing to absorb heat for transmission to the cooling medium.  The rotor includes a pair of end rings spaced longi-tudinally from the core.  The ends of the conductor bars in-clude recessed portions mounted in grooves in the end rings such that radially outer surfaces of the recessed portions are substantially flush with radially outermost peripheral surface portions of the end rings.  A weld metal layer ex-tends continuously around the radially outer surfaces of the recessed portions and the radially outermost surface portions of the end rings.  The combined radial dimension of each re-cessed portion and weld metal layer is less than the radial dimension of the non-recessed portions of the conductor bars to provide an air conducting clearance between the recessed portions and the stator windings.

Abstract: ABSTRACT  A time delay and integrate signal processing device has input taps for receiving a plurality of signals and has delay stages in the path of signal samples from the input taps arranged such that signal samples may be transferred from one stage to the next in response to a clock signal applied at a clock input.  In use, a clock signal having a duty cycle which varies linearly with time at a predetermined rate is applied, wherein the number of stages in the path of signals from each input tap is determined in accordance with a predetermined function of the rate of change of the clock duty cycle.  Embodiments of the invention may be employed to advantage in SONAR applications where signals are received from a plurality of transducers to scan a sector by constructive summation of signal returns.  The predetermined function may be chosen to minimise distortion during a scan and so scanning may take place at a higher rate than with prior art devices enabling full coverage of the sector with good range resolution to be achieved with a single device.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention concerns an improved gluing machine and a continuous method of operation which allows the gluing process to proceed at a rate that equals the feed rate of vacuum rotary document feeders.  The machine includes a unique registry and guide system for efficiently moving documents fed initially in an individual manner in a continuous, flowing manner from an initial input feed device to the gluing and registry point with the carrier.          The feed system not only allows substantially greater operating speeds but simultaneously overlaps documents while establishing and maintaining correct registration of the documents.  The documents are overlapped so that following documents are positioned beneath leading docu-ments. This overlapped condition together with the registry achieved within the feed system assures each individual document arrives in proper registry with areas of glue previously applied at preselected intervals on the carrier sheet.  The machine also includes a unique collection and refolding station for the carrier sheet and the documents attached thereto.

Abstract: ABSTRACT          Polymerization slurries of elastomeric isoolefin homopolymers and copolymers, such as butyl rubber, in diluents such as methyl chloride are effectively stabilized against agglomeration of polymer particles through addition of minor proportions of (i) a preformed copolymer stabilizer having both a lyophobic or lyophilic portion, or (ii) an in situ formed stabilizer from a functional lyophilic stabilizer percursor capable of copolymerizing or otherwise chemically bonding with the polymer product.  Agglomeration of polymer products is effectively prevented, yielding a number of sig-nificant processing advantages.  The process is especially adaptable to the production of isobutylene-isoprene butyl rubber.

Abstract: Case 4268-A     OCTANE MEASURING                   Abstract of the Disclosure Automatic octane measurements are made very rapidly with standard test engine using an all-electronic control that automatically lowers the fuel-air ratio to bring the knock intensity below standard, then automatically adjusts the compression to bring the knock intensity to standard, then intermittently increases the fuel-air ratio, after the first or second intermittent increase permits automatic compensatory compression changes only in the decreasing direction to compensate for departures from standard knock intensity and conducts these compensatory compression changes at a rate too slow for adequate compensation if the fuel-air ratio increase causes a substantial increase in knock intensity, and then indicating the compression ratio reading after the knock intensity remains standard during two to four successive fuel-air ratio increases. Maximum knock fuel-air ratio is indicated by subsequently automatically lowering the fuel-air ratio an amount corres-ponding to the fuel air ratio increases during which knock intensity remained at standard.  Finally for some purposes the test engine can be permitted to stabilize at the maximum knock fuel-air ratio.  Electronic memory can be used to translate compression ratio to octane number, and barometric correction can be made electronically.
