Abstract: Method of treating subsurface layers of the earth for controlling movement of subsurface water and building strength of the subsurface layers characterized by injecting at a plurality of predetermined depths and at a plurality of predetermined spaced-apart locations a lime-fly ash slurry consisting essentially of water, particulate hydrated lime and particulate fly ash; the particulate lime and fly ash being present as particulate solids and a proportion of from twenty-five percent by weight of the water to as much as two hundred percent by weight of the water when employed along. The particulate solids comprise lime and fly ash in proportions ranging from three parts lime to one part fly ash to one part lime to ten parts fly ash. The injection is carried out by pumping the slurry of one of the particulate solids and water through a jet slurry mixing apparatus for aspirating in the other dry particulate solid. Preferably the fly ash will be aspirated into a slurry of the lime in water.

Abstract: Means for supporting and driving agitators in commercial food mixers and the like as disclosed herein include structure for mounting and supporting the agitator(s) separately from the structure which rotatably supports the mixing bowl. The mixing bowl has a pair of spaced ends and is rotatably supported by trunnions fixed to such spaced ends and extending outwardly therefrom toward adjacent support frame members which have journals for rotatably cooperating with such trunnions to thereby support the mixing bowl. The agitator for the mixer is journaled in the spaced ends of the mixing bowl, such that the weight of the mixing bowl and the mix therein is not imparted to the agitator shaft. Preferably, th agitator is rotatably driven by drive-transmission means including drive gears disposed outside the mixing bowl and outboard of the support frame members but generally in alignment with the agitator shaft, and flexible drive means (e.g.

Abstract: Photosensitive solubilization inhibitor compounds of the formula ##STR1## wherein: x is an integer equal to the valence or functionality of the radical R, andR is a radical selected from the group consisting of the residue of a mono-, di-, tri- or polyfunctional alkanol or silicon-containing alkanol and is attached to the oxy atom of the carboxyl group through a carbon atom.Positive deep ultra-violet photoresists which are base developable comprise base soluble polymers and the photosensitive solubilization inhibition agents. Lithographic resist images are formed with the deep ultra-violet photoresists upon exposure to deep ultra-violet light.
