Abstract: A method, system, and computer program product are described capable of controlling an industrial based chemical process through accessing sensor data, pre-processing accessed sensor data through an automated process, forming an initial prediction model of the chemical process, and automatically determining linearity or non-linearity of the initial prediction model. As a function of quantitatively measured linearity, being non-linear, quasilinear, or linear, automatically train the initial prediction model, then deploy the trained prediction model in a manner that controls the subject chemical process at the industrial plant, including optimizing consumption of a certain resource. Data-driven modeling of non-linear, continuous-like industrial or chemical processes results.

Abstract: A power plug includes a conductive module, a pin, an adapter terminal and a circuit board. The conductive module includes an injection-molded insulating body and a contact terminal secured to the insulating body during an injection molding process. The contact terminal includes a tail portion extending beyond the insulating body from one side of the insulating body and configured to be connected to the pin, and a contact portion extending beyond the insulating body from another side of the insulating body and configured to mate with the adapter terminal. The adapter terminal is electrically connected with the circuit board.

Abstract: A leaf spring assembly includes a safety strap extending along the bottom of a plurality of stacked leaf springs that are held in a stacked relationship by a leaf fastener. The strap is attached to each leaf spring in the stack by fasteners at opposite ends of the spring such that adjacent leaf springs are connected on each side of the fastener. In the event that any one of the springs fails between the leaf fastener and one of the ends at which the strap is attached, the broken pieces of the spring remain connected to the other springs in the stack. This prevents pieces from breaking free of the assembly and creating road hazards in the event of spring failure.

Abstract: In an alternative assembly of multiple leaves in an assembled leaf spring; a forged fastener is used instead of a bolt and nut. To form the forged fastener, a cylindrical member with a preformed head on one end is inserted through the centre holes of each leaf of the leaf spring and the inserted end is forged in a press to match the head of the fastener on the other side. This is used to make a permanent connection, to make both sides of the fastener identical for use with an under-slung or over-slung axle arrangement, and to reduce process time by eliminating the need to cut and peen the conventional bolt.
