Latest Patents

One of Harold's latest patents is for a sealing means for slide gates. This invention features an improved sealing mechanism designed for slide gates that are mounted for opening and closing movement relative to a seat forming a fluid flow orifice. The sealing means includes a resilient sealing member that fits into a groove in the frame. This groove has an outer compartment that seals the body of the sealing member and an inner compartment that accommodates lateral displacement of the sealing member as the gate closes. This innovative design helps relieve forces that could shear the sealing member.

Another significant patent by Harold is for an adjustable bearing structure for butterfly gate valves. This invention is particularly useful for controlling water in treatment and wastewater plants. The butterfly gate valve features a one-piece shaft with a lower end that rotates in a radial bearing. The upper end of the shaft is equipped with both a radial bearing and a thrust bearing, which are housed in a protective bonnet. This design allows for easy access to the upper bearings through a removable bonnet cover, and the vertical position of the leaf within the frame can be adjusted using a rotatable threaded member.
