Abstract: A molten metal spray-depositing apparatus employs a magnetic field-generating nozzle for atomizing a molten metal stream into a spray of metal particles. The magnetic driving field generated by the magnetic atomizing nozzle generates eddy currents which produce an induced field in the metal stream opposing the driving field and creating a torque which causes the stream to break up upon exiting the driving field. The nozzle has one of two configurations for generating one of two generic magnetic field geometries. In one configuration the nozzle utilizes a pair of spaced magnetic poles, such as provided by Helmholtz coils, for generating a transverse magnetic field geometry across the stream. In the other configuration the nozzle employs a solenoid coil for generating a solenoidal magnetic field geometry parallel to the stream.

Means are provided for pivoting the nozzles transversely of the vehicle and, in the case of the roll-over washer, reaiming the nozzles so as to constantly direct air in a forward direction regardless of the direction of movement of the gantry frame relative to the vehicle.

Abstract: The present invention is a variably convergent exhaust nozzle includes a ring, pluralities of first inner leaves, second inner leaves, lever-arms and hinges and a cable for use with a ducted fan unit and a driving mechanism. The ring has a peripheral edge. Each of the first and second inner leaves is formed out of a semiflexible material and has a first and end and a second end. The first and second inner leaves are distributed along the peripheral edge of the ring. The first leaves are fixedly coupled to the ring at their first ends.

Abstract: In sand type filters, a pipe is often diposed beneath the surface of the sand bed and is rotatable on a vertical axis, located in the middle of the length of the pipe, horizontally and has nozzles extending along the trailing side of the pipe on each side of the axis of rotation. When these nozzles are supplied with fluid under pressure they cause the pipe to rotate and the water from the nozzles will agitate the filter and wash the soil therefrom, which can then be removed from the filter. A nozzle for this purpose is illustrated in my U.S. Pat. No. 3,351,292 and the present invention represents an improvement thereon by providing additional passages for fluid from the nozzle which not only assist in impelling the pipe in its rotary action but also provide for increased agitation of the filter bed.

Abstract: Flow spreading method and apparatus particularly adapted for use with a generally parabolic, slotted screening or dewatering surface, which redimensions the cross-sectional shape of a flow of material from a relatively narrow width, deep depth flow to a relatively shallow depth, wide width flow approximately equal to the width of the surface to which the flow is delivered. The apparatus includes a curved plate preferably having a substantially constant radius of curvature and a conduit which directs the material against the curved plate non-tangentially with respect to its surface to induce a smooth but rapid redirection and hence, redimensioning of the flow cross-sectional configuration. The conduit feeding the material may have at least its terminal portion constructed of a flexible material which allows the conduit outlet to be pressed against the surface of the curved plate and deformed somewhat to enhance flow spreading while still permitting the passage of relatively large objects through the conduit.
