Abstract: ABSTRACT OF THE DISCLOSURE           A method of generating mixed and atomized fluids is disclosed in which at least two fluids selected from gases, liquids and powders, are flown through a flow passageway including a first convergent and a subsequent divergent flowing zones, whereby the fluids are subjected to change in pressure, thereby being mixed and atomized.   The mixed and atomized fluids are spouted from a second convergent flowing zone at a high speed toward a fluid reflecting means.   The spouted mixed fluids collide with the fluid reflecting means and are further mixed with one another and further atomized when the mixed fluids are reflected from the fluid reflecting means.   A fluid spouting composite nozzle unit for practising the method is also disclosed in which a first nozzle has the first convergent flowing zone and the divergent flowing zone, and a second nozzle has the second convergent flowing zone.   The fluid reflecting means is disposed on the downstream side of the spouting hole of the second nozzle.   The first and second nozzles and the fluid reflecting means are interconnected so that an assembled unit is formed.

Abstract: ABSTRACT OF THE DISCLOSURE         A phase synchronizing circuit for reproducing a synchronizing carrier wave from an N-phase carrier signal which is phase shift keyed (PSK) is disclosed, N being equal to 2n where n is a positive integer.  The circuit includes a voltage controlled oscillator and an N-phase demodulator supplied with the modulated signal and the output signal of the voltage controlled oscillator.  The output of the demodulator is supplied to a code converter of the form N-ary (e.g. N-ary is binary when n is 1).  The output of the N-ary code converter is supplied to a first input terminal of an N-phase modulator.  A first delay circuit is installed between the modulated signal input terminal of the demodulator and a second input terminal of the modula-tor.  A phase detector has a first input terminal supplied with the modulator output.  A second delay circuit is installed between the output terminal of the voltage controlled oscillator and a second input terminal of the phase detector.  A low-pass filter is connected between the output terminal of the phase detector and the input terminal of the voltage controlled oscil-lator.  A variable phase shifter is connected in one of the paths between the modulated signal input terminal and the second input terminal of the modulator, between the output terminal of the voltage controlled oscillator and the second input terminal of the phase detector, and between the output terminal of the phase modulator and the first input terminal of the phase detector.  The carrier wave phases may be varied by changing conversion states of the code converter.

Abstract: Abstract of the Disclosure A compact optical bench type unit for making selected color-component records of color transparencies for use in color printing comprises a light source with a rotary filter disc for directing a beam of selectively colored light through a light condenser which converges the beam through a color diapositive to be reproduced and into the objective of a camera.  The condenser, possibly formed of Fresnel lenses, is of large dimensions to accommodate large diapositives, and the camera objective has a relatively short focal length.  Chromatic aberration of the condenser is corrected by moving the light source in correspondence with rotation of the filter disc, or by selectively inserting correcting lenses in the beam.

A finely divided refractory inor-ganic oxide, preferably as alpha-alumina monohydrate, is admixed with a peptizing agent and sufficient water to produce a mixture which has a weight loss on ignition at 900°C. of from about 50 to about 70%. The mixture is subjecting to shear-mixing, the intensity or severity of the shear-mixing being characterized by an energy input equivalent to from about 15 to about 120 watt-hours per pound of dry refractory in-organic oxide contained in said mixture over a period of from about 0.5 to about 5 minutes.  The resulting dough is subsequently extruded and the extrudate calcined.

Abstract: Abstract of the Disclosure An electrode assembly for electrical resistance welding apparatus is disclosed.  The assembly includes a mounting, and at least two spaced anvil blocks carried on the mounting.  At least one of the blocks is carried for displacement relative to the mounting and at least one of the blocks provides an electrode.  A cam arrangement moves the displaceable anvil block or blocks relative to the mounting so that the blocks can engage and clamp a workpiece to be welded.  Electric current can be passed to the or each electrode anvil block through the mounting; the or each electrode anvil block can serve to support the workpiece during spot welding of a second workpiece thereto when a secondary electrode is positioned in contact with the second workpiece in the vicinity of the electrode anvil block.  The electrode anvil block of the invention thus serves to effect partial clamping of the workpiece during spot welding and also provides a firm base against which the welding is effected.

Abstract: KITCHEN VENTILATOR DAMPER ACTUATOR AND CONTROL     Abstract of Disclosure This invention relates to a kitchen ventilating system, where a kitchen hood communicates through an exhaust duct to the exterior atmosphere, where a fan in the duct operates for powered venting of the kitchen, and where a damper can be closed to separate the kitchen from the exhaust duct.          This invention teaches means for shifting the damper between the closed position and the open position, which means is a fluid power actuator in the form of a power cylinder.  The power cylinder is operated by water, typically from the same source as the regular kitchen water, and control valve means utilized between this source of water under pressure and the cylinder controls the shifting of the damper.  The preferred system provides that the valve means shifts by spring pressure to the position corresponding to where the damper is closed and is electrically shifted to open the damper, so that should a power failure occur the damper will automatically be closed.          Also, there is a pressure tank that retains sufficient water pressure to close the damper, even though the source of water may actually have inadequate or total loss of pressure.

Abstract: ABSTRACT OF THE DISCLOSURE      The apparatus and method of the invention employ a gas torch which has the feature of selective addition of metal powder to the gas flow.  In use, the torch is caused to make a continuous succession of traverses of a workpiece region for preheating purposes and then, without interrupting the continuous operation of either the torch or the traversing cycles, a controlled flow of metal powder is caused to enter the torch flow, enabling the bonding and progressive building of a metal coat to desired thickness.  In the embodiments described, first and second different metal powders are thus successively coated to the substrate without interrupting the continuous operation.          Different embodiments are described in the particular context of applying uniform circumferential coatings to a cylindrical workpiece such as a shaft.
