Filed:

Sep 27, 1984

Appl. No.:

6/655369

Inventors:

Myron E. Mantell - Morris Plains NJ

International Classification:

F04B 2100
F04B 4306

US Classification:

417 63

Abstract:

In accordance with the present invention, the imminent failure of a diaphragm due to the attack by a corrosive or a solvent or mechanical fatigue is predicted through the use of a diaphragm pump having a housing, a first chamber within the housing, a second chamber within the housing and a diaphragm mounted in the housing between the first chamber and the second chamber. The diaphragm is of a chemically inert, electrically non-conductive material which contains an interconnected, electrically conductive material extending within the diaphragm less than the full radial dimension of the diaphragm. The conductive material is approximately equally spaced from the two opposing surfaces of the diaphragm. The electrically conductive material is advantageously, an electrically conductive graphite and takes the form of a mesh, screen or web of conductive fibers, filaments or strands.

Abstract:

The invention relates to a shredding apparatus for use in shredding a material mass into a plurality of discrete particles. The principal components includes a shredding screen and wiper blades. The wiper blade include a semi-rigid blade having its lower end in firm contact with said shredding screen. Reciprocating means is fixed to the shredding screen means to provide reciprocating motion of the shredding screen relative to said wiper blade. The reciprocating means produces a length of travel of said shredding screen at least equal to the space between an adjacent pair of wiper blades. Each of said wiper blades are parallel to each other and to a first set of spaced parallel bars. A second set of spaced parallel bars are substantially perpendicular to the first set of spaced parallel bars thereby forming a plurality of openings having a predetermined cross-sectional area substantially equal to the required cross-sectional area of said discrete particles. During each pass of the reciprocating motion the lower edge of each wiper blade repeatedly slides along the top of a bar of said first set of spaced parallel bars, snaps downward towards the second set of spaced parallel bars.

Abstract:

An influent stream is passed through a filter bed separating contained particulate material from the mother liquor; the process being carried out until such time as the filter bed can no longer practically sustain further separation operation. A wash step is then commenced in which a wash liquor is passed through the filter bed, washing soluble components sorbed or deposited on the filter bed or in the filter cake. The concentration of soluble salts in the wash liquor is sensed and when the concentration reaches a predetermined minimum level, the wash liquid flow is stopped for a predetermined period of time. The flow is then resumed for a predetermined minimum time period and if the concentration of soluble salts in the wash liquid is, at the end of said minimum time period, not above a predetermined minimum level, the wash step is terminated. Otherwise, the wash step is intermittantly repeated until such time as the aforenoted termination occurs.

Abstract:

In accordance with the present invention, a diaphragm pump having a housing, a first chamber within said housing, a second chamber within said housing and a pair of diaphragm elements mounted in said housing between said first chamber and said second chamber, is provided with a failure sensing system for the diaphragm. The failure sensing system including a failure sensing device which is between the two parts of the diaphragm and an indicator circuit which includes the conductive liquid which is being pumped and an alarm. The two parts of the diaphragm element are clamped together proximate their peripheral edge such that a circumferentila fluid tight compression seal region is provided. The sensing device includes an electrically conductive lead which extends from the exterior of the housing, through the circumferential fluid tight seal region into the region peripherally inward of the seal region. The electrically conductive material is, advantageously, an electrically conductive graphite and in the form of a filament, fibers or strands.
