Abstract: Systems and methods for predicting replacement of a component of an industrial machine. One system includes an electronic processor configured to determine a wear rate of the component based on a current dimension of the component and historical dimensions of the component and determine a replacement cost for the component. Determining the replacement cost includes determining a cost of downtime for replacing the component based on a time for replacing the component and a downtime cost for the industrial machine during the time for replacing the component, a material cost in replacing the component, and an operating cost of the industrial machine associated with not replacing the component. The electronic processor is also configured to determine a replacement recommendation for the component based on the wear rate, the replacement cost, and discard criteria and output the replacement recommendation.

Abstract: A safety relief valve is provided that comprises a body comprising a chamber therein and an inlet and an outlet, the inlet comprising an inlet valve seat; a disk member closable on the inlet valve seat; and a mechanism in the body biasing the disk member to rest on the inlet valve seat with a set force such that when the pressure in the inlet exceeds a set pressure resulting from the set force, the disk member is lifted from the inlet valve seat, the mechanism comprising a combination of a coil spring and one or more disk springs stacked in series with the coil spring. A method of preparing a coil spring for use in a pressure relief valve comprises measuring the spring rate of the coil spring and; modifying the spring so as to modify its spring rate to be within ±2% of a desired spring rate.

Abstract: The invention may be summarized as follows. The present invention provides insecticides comprised of naturally-occurring compounds, such as, for example, PA1b-related peptides and terpenoid saponins. The present invention also provides for identification and characterization of a synergistic insecticidal effect between peptides and saponins extracted from plants. Furthermore, simplified extraction procedures are provided that avoid the use of a chloroform defatting step or a column chromatography step.

Abstract: A modulating relief valve comprising a main relief valve and a dome pressure control system. The main relief valve has an inlet subject to system pressure, an outlet, a valve member normally sealing the inlet, a piston that rises and falls wit the valve member, and a dome adjacent to the piston, the dome having a dome pressure. The dome pressure control system is attached to the main relief valve.
