Abstract: A two-way ball valve including a housing having an open interior chamber or space with opposed inlet and outlet openings, apertured ball seats operatively positioned in the housing at the junctures of the inlet and outlet openings, a ball in the chamber floatingly seated between the ball seats and in liquid sealing engagement therewith, an axial flow bore through the ball, the ball being rotatably positionable to open and closed positions, and a large bore or opening in the body of the ball in the nature of a side channel intercommunicating the axial flow bore and the interior space in the housing, and with the valve in open position permitting fluid to circulate freely within the housing to flush the housing space and thereby prevent formation of contaminated dead spaces in the valve.

Abstract: The case assembly for a ceramic tile die includes a die cavity assembly formed by an insert support member and a plurality of inserts mounted on the upper surfaces of the insert support member. The inserts are preferably formed of tungsten carbide and may be universally mounted on the insert support member to provide a plurality of usable wear surfaces. A rigid frame surrounds the die cavity assembly, and mounting means are provided to permit limited, pressure induced movement between the die cavity assembly and the rigid frame. This minimizes the tensile stress to which the walls of the die cavity assembly are subjected.

Abstract: A pile splice is disclosed which completely satisfies the need for such a device which will enable structural analysis of the loads and stresses induced therein, which is simple and economical; which may be readily completed in the field with a minimum of construction equipment and comprises a pair of mating plates having machined abutting surfaces, one each carried by the pile section and embodying an outwardly projecting flange circumscribing the joint area. A tension band is applied to the flanges being comprised of two halves which are joined together at diametrically opposed points by upper and lower fillet welds so that the only stress in the bands is hoop stress induced by tension or bending and shear and the mating plates act in compression as a solid joint whereby all of the loads and resulting stresses in the joint section may be calculated by accepted stress-strain calculations.
