Patent number: 6510781Abstract: An adjustable packing gland assembly is mounted for adjustable engagement with a seal and a packing in a fluid pumping apparatus for sealing against fluid leakage about reciprocating plungers and like pumping elements, the adjustable packing gland also stabilizes the pumping element. A stuffing box is formed in the pump housing and spaced packing gland shoulder bolts bottom out on that housing. A packing gland is disposed in the stuffing box and is slidably mounted on the spaced adjustment studs, each of the shoulder bolts having adjusting nuts and pipe sleeves disposed for precision adjustment of the packing gland. Bearing against the plunger on either side of the packing and seal are guiding elements made of a low wear material which possesses lubricity as against the plunger. The upper guide may be integrally formed with the gland. An eccentric liner is made of a similar material as the guides, rendering it a low wear item in need of little or no lubrication.Type: GrantFiled: July 16, 2001Date of Patent: January 28, 2003Assignee: Komline-Sanderson Engineering Corp.Inventors: Jeffrey Pecca, Frank Leotti, Jr., John Diekman

Patent number: 5545333Abstract: A belt filter press having a wedge zone which can be adjusted during operation of the filter press to prepare a sludge or other material to be deliquified in the most efficient manner for high pressure deliquification also includes a sealing arrangement for sealing the marginal edges of the upper and lower belts, a tapered slide cam assembly on either side of the belts for adjusting the wedge angle in a controlled manner, rack and pinion assemblies associated with hydraulic cylinders on either side of the belts to ensure the uniform movement of the lower belt supports, and the staggered arrangement of upper and lower belt support members where the lower belt support members are concave-like in shape to facilitate the sealing of the marginal edges of the belts, as well as to form a confined pocket which will facilitate the shearing action induced in the material to be deliquified.Type: GrantFiled: May 26, 1995Date of Patent: August 13, 1996Assignee: Komline-Sanderson Engineering Corp.Inventors: James A. Louden, Brian F. Hawkins, Wayne D. Hann, Sr., deceased

Patent number: 4257891Abstract: A pressure reducing control valve assembly for feeding an aeration fluid stream to a flotation tank includes a pair of overlapping discs, one having a central opening and affixed to an end of a tube, and the other imperforate and outwardly movable away from the surface of the fixed disc to define a valve opening having a predetermined land width. Optimum size of air bubbles for the objective desired is obtained by controlling the dimensions of a shear zone established by the land width within which the fluid stream is intensely turbulent for a short period of time, thereby causing air bubbles to form and then be discharged immediately into the liquid within the tank without having had time to coalesce.Type: GrantFiled: September 26, 1979Date of Patent: March 24, 1981Assignee: Komline-Sanderson Engineering Corp.Inventor: Arthur R. Albohn
