Abstract: An attemperator in the form of a steam desuperheater is disclosed herein and comprises a water tube adapted to be connected to a source of water under high pressure and a spray tube communicating with the water tube through a flow-control device for controlling the flow of water from the water tube to the spray tube. The spray tube is adapted to be located in a steam line for injecting cooling water into the steam when its temperature exceeds a predetermined temperature and accordingly is formed with one or more nozzles for injecting a spray of water travelling along an expanding swirling path into the steam, the water being atomized into small droplets which easily evaporate in the steam. Preferably, a plurality of nozzles are provided arranged in rows extending axially of the spray tube and the rows are circumferentially spaced apart. Also, the nozzles preferably communicate with the inside of the spray tube through a series of small ports.

Abstract: A shower head includes a tubular body or housing defining a fluid passage which is connected by a plurality of angularly disposed parts directly to a corresponding plurality of fluid chambers. The chambers are defined by axially extending partitions formed as an integral part of the discharge end portion of the housing and are enclosed by a perforated cover member removably secured to the housing. A fluid driven turbine-type valve rotor is supported within the fluid passage by a center pin shaft and includes a projecting closure portion which has a rotating path adjacent the ports for successively closing the ports and momentarily restricting the flow of fluid from the fluid passage into the corresponding fluid chambers. When it is desired to discharge a steady spray, either the cover member is partially released from the housing to provide for fluid communication among the chambers or rotation of the valve rotor is stopped at a predetermined position.

Abstract: A broad washing machine comprising a housing containing several groups of guide rollers, each group consisting of two columns of parallel horizontal rollers between which a textile web is upwardly conveyed along a zig zag path consisting of short mainly horizontal loops, a receptacle being positioned under each roller for catching the cleaning liquid dripping from the web and for directing said liquid upon the upper flight of an adjacent loop.

Abstract: A device is provided for moistening the plate cylinders of offset printing machines. The device includes an inner rotatable sleeve having an air passage extending therethrough. Angularly extending passages are provided in the inner sleeve. The inner sleeve is rotatable within an outer fixed cylinder having spaced apertures all directed in the same direction. A film of water flows over the fixed cylinder. As the inner sleeve rotates air is forced through the inclined passage to force the water against a focus upon a diffuser which breaks the water up into a fine spray which is deposited upon the surface of a water cylinder so that the water is deposited from end to end thereof so that the plate is provided with a film of water throughout its length.

Abstract: An apparatus for distributing a controlled flow of water onto passing hot strips in proportion to the varying width of strips as they issue from a hot strip rolling mill.
