Abstract: A method and apparatus for accomplishing stress relief in fabricated structures by application of dynamic loading induced by vibration to relieve residual stresses sufficiently to achieve dimensional stability. Maximum dynamic loading of the structure by use of an accelerometer attached to the structure is obtained by scanning a range of vibration frequencies to arrive at maximum output of the accelerometer corresponding to the maximum in the dynamically applied loading and tuning the vibration to a frequency corresponding to the peak in the acceleration curve.

Abstract: A fluoroelastomer-hollow glass microsphere coating has been found to provide new and unexpected corrosion resistance to metal surfaces for protection against severely corrosive environments. The coating comprises a fluorocarbon elastomer and 3-50% by volume of hollow glass microspheres or microballoons having a size in the range of about 2-300 microns, preferably 20-200 microns. The hollow glass microspheres or microballoons substantially increases the corrosion resistance of a fluoroelastomeric liquid composition, yielding new and unexpected thermal and chemical resistance, particularly when the coating composition is applied in two or more layers.

Abstract: A differential pressure gauge of the type comprising a controlling magnetic helix device carrying a pressure indicating pointer, the position of which is controlled by a magnet magnetically coupled to same and mounted on the free end of a helically coiled bourdon tube exposed to differential pressures within the gauge and anchored in the gauge housing at its other end for this purpose. The magnet has a planar pole face paralleling the axis of the helix and defines a magnetic axis that is normal to and intersects the helix axis. The gauge housing defines an integral one piece pressure wall that separates and physically seals the helix from the magnet and bourdon tube and defines within the gauge housing pressure cavity an operating space within which the magnet and its supporting bourdon tube are mounted and operate.

Abstract: A water conditioning system is provided with an improved resin regeneration arrangement. Included in this system is a flow control valve associated with a brine injector mechanism which provides for a very slow rinse of the treatment resin at the end of the brine draw cycle. This provides for greater interaction between brine and resin and, therefore, more efficient and economical use of salt. The flow control valve utilizes a floating ball and a notched seat to permit substantially unrestricted flow when the ball is floating and brine is being supplied to treatment tank and greatly restricted flow when the ball is seated and untreated water is being used to rinse the brine from the treatment tank.

Abstract: A conveyor belt cleaner mounted on a transverse support member including an arm extending from a mounting bracket and a belt cleaner blade secured on the arm. A positioning arrangement is provided between the arm and the cleaner blade to allow the blade to rotate about the central axis of the arm within predetermined limits in either direction so as to allow the scraping edge of the cleaner blade to align with the surface of the conveyor belt being cleaned. A nut and a resilient washer are provided to secure the blade against a collar. An alternative securement includes a pin-and-slot connection which allows the same rotative action of the blade relative to the arm and having multiple seals against the entrance of dirt into the connection.

Abstract: This invention relates to a nozzle having a restriction in the form of an insert comprised of a pre-metering orifice in the nozzle that causes the emerging stream to flare out and impinge on the nozzle side walls and create turbulence to flood the nozzle and achieve a predetermined spray pattern. The premetering insert is formed to provide a non-uniform orifice length and is installed immediately ahead of the nozzle to reduce the velocity of the stream without disrupting the spraying performance of the nozzle and one or both parts are made from a plastic material such as nylon.

Abstract: The invention comprises an atomizing spray nozzle having an expansion chamber containing an impingement plate, or table and wherein a flow of liquid is introduced as a high velocity stream which strikes the impingement table and breaks up into finely atomized particles which are struck by a high velocity air stream in a direction at an angle to the direction of the liquid stream to further atomize the liquid particles as the mixture atomizes adjacent the impingement table and passes into a mixing area in the barrel of the nozzle. The nozzle includes a jet forming inlet for the liquid aimed from one side of the nozzle at the impingement table in the expansion chamber, an air inlet orifice member secured in one end of the nozzle at an angle to the liquid inlet and at one side of the expansion chamber with the nozzle barrel at the downstream side of the expansion chamber and an exit orifice member secured in the open discharge end of the barrel.
