Abstract: A screening panel and screening arrangement are provided for screening materials. The screening panel includes a peripheral frame having a first side frame member and an opposing second side frame member defining an opening therebetween. Further, the screening panel includes a plurality of spaced elongated screening ribs defining a screening surface of the screening panel. The screening panel includes a one or more sets of screening ribs that extend continuously across at least a portion of the screening surface of the screening panel in a non-parallel direction relative to a flow direction of material in the screening arrangement.

Abstract: A glass filler defines a main body having a lower surface. An inlet and outlet are each defined in the lower surface of the main body. An outlet chamber is defined in the main body and contains an outlet valve, which includes an outlet valve housing defining a castellated edge. The outlet valve includes a cylindrical sleeve that defines an inner surface that is crenellated and configured to receive an implement that can be inserted and used by the operator to rotate the cylindrical sleeve in a manner that controls the amount of liquid exiting the outlet of the glass filler.

Abstract: A spray valve is configured with a fluid path that always provides dynamic water flow on both opposite surfaces of the seating flange of the valve stem when the valve is almost completely closed and when the valve is just beginning to be opened. This equalization of dynamic pressure from the incoming water flow tends to reduce the frequency of vibration that is imposed upon the valve stem and biasing member by the incoming water flow. A check valve is built into the spray valve, which has a trigger lock and a selectively removable spray disk. The valve has an outer sleeve that surrounds the valve's base member and defines a gap therebetween and is formed of mechanical shock-resilient, heat-insulating material.
