The suspensoid has shear thinning rheological properties so as to be pumpable with a lower apparent viscosity than its at rest viscosity.

Abstract: A firearm safety device comprising a pair of combination lock type dials mounted concentrically and rotatably on the gun casing. The dial in contact with the casing has an aperture spaced a selected radial distance from the center. The other dial has a pocket spaced the same distance so that they may be aligned together. A plunger is mounted in the casing at the same distance and is spring biased outwardly and axially movable. The inner end of the plunger is extensible into a moving part of the firing mechanism. Aligning the pocket and aperture with the plunger allows it to spring out of engagement with the moving part, therefore releasing the safety, or unlocking the firearm. Sloping grooves adjacent the pocket and aperture depress the plunger when the dials are rotated.

Abstract: A deep well pump system incorporating a sub-surface pump unit and a surface power unit with a fluid column formed therebetween. The pump unit incorporates a counterbalance means that is specifically illustrated as a collapsible volume chamber operably engaged with a pump piston to cause a fluid pumping linear movement of the piston responsive to the selective contraction and expansion of the collapsible volume chamber. The power unit, in the charging stroke thereof, pressurizes the fluid column by the introduction of a volume therein sufficient to contract the collapsible volume chamber, with a subsequent pressure buildup effecting discharge of additional fluid from the power unit with less valving than the prior art pumps.
