    Abstract: A method of applying and removing a fluid actuated nut, the nut having a cylindrical casing engageable at an inner end with a base, the casing containing a coaxial relatively axially shiftable plunger having an inwardly opening partial central bore for threadedly receiving a shank of a bolt, a compression spring acting outwardly on the plunger and inwardly against the casing, and a fluid pressure chamber outwardly of the piston, the nut being applied by screwing the piston onto the bolt shank to the point of engagement of the inner end of the casing with the base and tightened by sequentially compressing the spring by fluid injected under pressure in the fluid chamber for shifting the casing away from the base, turning the casing to reengage the base and releasing the fluid pressure to expand the spring, and repeating the sequence as necessary to produce the desired tensile and/or compressive force, the nut being removed by applying fluid pressure to advance the piston for compressing the spring and disengaging the casing from the base and then unscrewing the piston from the bolt.

    Abstract: A screen panel retainer assembly, that is utilizable with a vibrating separatory machine, is configured with a plurality of discrete, mushroom-shaped screen panel retainers. Each such retainer has a retainer head that is generally in the shape of a portion of a cylinder, such as a right cylinder. A shank connects each such retainer head to a suitable retainer bar. The retainer bar can be adapted to be attached either to screen stringer tubes of the vibrating separatory machine, or to underlying cross tubes and end cross tubes. The screen panels, which are to be secured to the vibrating separatory machine, have complementary shaped mushroom-shaped screen panel retainer head receiving chambers in their side surfaces. Two such panel edges define a whole chamber. The retainer heads are metal whereas the screen panel edges are resilient. The mushroom-shaped heads securely snap into their complementary chambers yet can be removed from those chambers when the screen panels have to be replaced.

    Abstract: Air entrained, super plasticized concrete having a maximum bubble spacing factor of 0.008 inch (ASTM Standard C 457) and a method for preparing such concrete are disclosed. The method includes the steps of adding an air entraining agent while mixing aggregates and water, adding during the mixing a small but effective quantity of a potassium salt of a fluorinated alkyl carboxylate having a high surface activity and a pH of 8-9, and then adding a super plasticizer to the resulting mix prior to placement. The air entrained concrete having the aforesaid bubble spacing factor contains a super plasticizer, a vinsol resin air entraining agent, and a potassium salt of a fluorinated alkyl carboxylate. The fluorinated alkyl carboxylate is present in an amount of one to two parts per 100 parts of the super plasticizer on a weight basis.
