摘要： A powder injector assembly for delivering powder into an axial flow of heated gas of a powder coating applicator. The assembly includes a powder injector rotatable in a plane whose centerline is perpendicular to the gas flow for issuing powder thereto. An injection nozzle exit port is integral with and leads from the injector and is disposed in the centerline for angular rotation thereabout, and is alignable into the gas flow for powder melting and subsequent substrate deposition. An integral cooling system maintains the powder in a non-melted state until its exit. The injector is independently movable laterally, axially, and angularly for respective radial, axial, and angular movement of the injection nozzle exit port. Angular movement occurs along a centerline passing through the tip of the nozzle exit port to thereby permit independent angle adjustment without changing axial or lateral locations of the injection point.

摘要： A heating system has a substantially cylindrical hollow muffle formed of a alumina ceramic with a plurality of heat-generating windings therearound. A light-actuated power control is operatively connected to the windings. A computer is operatively connected to a temperature monitor associated with an article being heated in the muffle. The computer is also operatively connected to a light-signal generator and provides commands to the generator in the form of a train of equidistantly spaced electrical pulses in response to temperature measurements provided by the monitor such that an article can be heated to an elevated steady state temperature and controlled at that steady state temperature within precise predetermined limits. The precise temperature control makes the system particularly valuable in the fabrication of crystals with uniform properties or having special growth requirements.

摘要： A plasma generating system comprises a plasma gun including a hollow cylindrical anode member, a hollow cylindrical intermediate member electrically isolated from and juxtaposed coaxially with the anode member to form a plasma-forming gas passage through the intermediate member and the anode member, and an axially movable cathode member. The intermediate member comprises tubular segments separated by resilient insulating spacing rings held in compression. Arc radiation is blocked from the spacer rings by meanders in the inter-segment slots and further by ceramic barrier rings. An electric motor or pneumatic piston responsive to a measurement of arc voltage continually adjusts the axial position of the cathode tip relative to the anode nozzle so as to maintain a predetermined arc voltage.
