Abstract: A gas heating appliance of the kind having a gripping handle through which fuel is supplied to a common feed pipe carrying a plurality of burners. Each burner has a separate nozzle branched off the feed pipe and a pair of opposing curved baffle walls are provided at each nozzle, the walls of each pair being separated by gaps at each nozzle, all the gaps being in mutual alignment. The appliance of the invention is particularly applicable to the heating of plastic foil type materials.

Abstract: A fitting coupled to a water source, comprising an orifice, means for regulating the quantity of water passing through said orifice, an abutment for water passing through said orifice, and laterally displaced water outlet means.

Abstract: A showerhead of the type including an inlet end, an outlet end, and a bore defining a passage between the two. Two discs are disposed in the passage, in face-to-face engagement with each other and mounted for relative rotation about a central axis. A plurality of orifices, arranged with their centers spaced at regular intervals around a circle of predetermined diameter, extend through each disc. Each orifice of the downstream disc defines a small port at the downstream face and a large port at the upstream face of the disc. Each orifice through the upstream disc defines at its downstream face a port that communicates with but is smaller than a respective port at upstream face of the downstream disc.

Abstract: A hair spray assembly is provided to substantially limit and confine the divergence and radial projection of spray emanating from a shower head into a generally cylindrical spray zone and to substantially prevent splashing and dripping of the water spray outside of that spray zone. This invention is particularly useful for professional hair care and treatment, such as permanent waving, frosting of the hair and shampooing and structurally includes a portable nozzle having a body with a diverging mouth that defines an outlet and a tubular inlet that telescopes into a flexible hose. A shower head having an annular flange is secured to the body of the nozzle and includes an apertured disc that covers the mouth of the nozzle and a rigid rim portion that extends axially forwardly of the apertured disc. A waterproof annular skirt engages the shower head and includes a lip portion that extends axially forwardly of the rigid rim portion.

Abstract: A spray dispenser for dispensing a spray of a liquid material has a cylindrical container with a nozzle adjacent one end thereof directed generally at a right angle to the longitudinal axis of the container. A mouthpiece of resilient material is pivotally mounted on the one end of the container so that in the storage position it has the axis aligned with the longitudinal axis of the container and it is easily pivoted to the dispensing position at right angles to the axis of the container and around the nozzle by simple pressure on the non-dispensing end thereof and is easily pivoted back to the storage position by pressure on the dispensing end.

Abstract: A carbon-dioxide (CO.sub.2) snow-making system comprising a snow horn having an upper chamber into which pairs of jets of CO.sub.2 are transversely injected from opposite directions, respectively. The expanding jet mixtures of snow and vapor are directed into collision along paths that lie generally in a single plane so as to intersect at an angle of 180.degree. in a central region of the chamber, thereby to dissipate the kinetic energy of the jets. Where more than two jets are directed into collision at a common point, the intersecting angles are so chosen that the resultant kinetic energy is substantially zero. High velocities and turbulence of the snow-vapor mixture are thereby minimized, and the snow discharges evenly from the chamber and through the horn without sticking thereto for uniform distribution.

Abstract: 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 practicing 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.

Abstract: A showerhead is disclosed which provides for a substantially constant volume of water throughout with a varying water pressure source having a metered orifice in response to water pressure acting against a spring and a directional orifice which directs water against a bubble generator plate to aerate the water emanating from the showerhead.

Abstract: A fluidized bed type spent activated carbon regenerator with an upper drying chamber and a lower reactivating chamber within a column through which spent activated carbon particles are treated in a fluidized state. The regenerator has a distributor at the lower end of a spent carbon feed pipe which opens into the upper chamber to distribute the feed of spent activated carbon uniformly on all sides of the feed pipe and over a larger area in the upper chamber. A hood is mounted around an upper end of a first overflow pipe which provides a passage to the lower chamber for carbon particles devolatilized in the upper chamber to block shortpasses of incompletely devolatilized carbon particles to the lower chamber. The regenerator is further provided with a louver strainer at the ceiling of the upper chamber to block fine carbon powder which tends to leave the regenerator entrained in upward streams of a regeneration gas flowing through the upper chamber toward a gas outlet at the top of the regenerator.

Abstract: A shower head having a main body with a passageway extending therethrough and adapted to be connected to the end of a water supply pipe, an annular skirt attached to the outlet end of the body and a multi-apertured disk mounted on the body for breaking up the water flowing through the passageway into a series of high velocity jet sprays, said apertures so positioned as to direct the jet sprays downwardly in a relatively diverging pattern into engagement with the lower edge of the annular skirt to diffuse the sprays as they leave the shower head.

Abstract: An apparatus for treating a surface with a liquid has a support displaceable over the surface and carrying a spray beam itself provided with a plurality of nozzles directed at the surface. A diffuser surrounds a plurality of the nozzles and has a deflector for diverting the streams of liquid emitted by the nozzles so that these streams flow in a direction generally parallel to the surface being treated. Rollers maintain the front face of the deflector a predetermined distance from the surface being treated. The spray beam may be in two sections which are oppositely reciprocated to increase the treatment effect.
