Abstract: FLUID TREATER HAVING INTENSIFIED ELECTRIC FIELD       ABSTRACT OF THE DISCLOSURE     A fluid treater relies upon the presence of an electric field in a treating region, without electrical cur-rent flow, to cause solids suspended in the fluid to pre-cipitate therefrom after the fluid has passed through the treater.  The treater has concentrically disposed elec-trodes, the inner of which is negatively charged and is bare, having direct, physical contact with the fluid flowing in the region between the electrodes so that the electric field pro-duced in such region is greatly intensified, thereby ac-celerating and promoting the action of the field upon the         : fluid. The housing of the treater is constructed from a suit-able polyvinyl chloride resin and serves as a dielectric be-tween the electrodes to prevent electrical current flow through     :. the treating region.  The dielectric housing enables the treater to withstand high power applications, thereby further promoting precipitation.

Abstract: ABSTRACT OF THE DISCLOSURE     A direct arc electric furnace having a tiltable base for pouring molten metal from the furnace. A refractory lined hearth supported by the base is pivotal with respect to the base for tilting to a degree greater than that capable by the base.  The furnace includes shell refractory lining material supported upon the hearth encompassed by a removable shell.  Replacement of the shell lining is accomplished by removing the shell, collapsing the shell lining into the hearth, and tilting the hearth with respect to the base sufficiently to dump the collapsed lining from the hearth into the pit adjacent the furnace.  Further, the use of the tilting and removable hearth permits the hearth to be removed from the base, inverted in the pit, and the re-fractory lining of the hearth may then be readily removed for replacement purposes.

Abstract: CHEMICAL PROCESS          FOR MEASURING TENDERNESS OF COOKED MEAT          ABSTRACT OF THE DISCLOSURE    To predict the tenderness of cooked meat, the concen-trations of certain trace elements such as copper,  cobalt, iron, zinc, calcium, selenium and silicon and sometimes cadmium and lead  in uncooked meat muscle are measured in samples taken from the carcass of the animals and samples from the same muscle are cooked and rated by a sensory taste panel (STR scores).  A formula is obtained by multiple linear regression of the data using the concentrations of trace elements as the independent variables and STR as the dependent variable.  To grade a carcass the concentrations of measured trace elements are entered into the formula and a predicted STR is calculated.  The ratio of the concentration of iron to zinc provides an especially suitable independent variable because of its high correlation with tenderness and the ease of measuring zinc and iron accurately.

Abstract: A METHOD AND MOLD FOR FORMING SHEETS HAVING REDUCED SURFACE IMPERFECTIONS           Abstract of the Disclosure A mold for compression molding a plastic sheet from a viscous fluid provides more resistance to flow on the side of the sheet designed to be the underside than on the side of the sheet designed to be seen.  This re-sistance to flow can be imparted by roughening the under-side of the mold more than the top surface of the mold. The purpose for roughening one surface of the mold more than the other is so that the plastic mass will flow faster on the smoother side of the mold and carry bubbles to the rough side of the mold via a rolling action. By this method employing textured molds, the surface of automotive panels can be made having reduced surface imperfections.
