Publication number: 20140015155Abstract: The invention utilizes temperature sensing to measure the internal temperature of an underground structure, such as a pipe, for the purpose of determining a proper cure interval and/or mix ratio of a resin system during a lining operation. A temperature sensor is placed within a pipe or other underground structure to be rehabilitated and at least one temperature measurement is taken within the structure prior to or simultaneously with the installation of a liner. Once the temperature of an internal aspect of the structure is taken, a cure schedule is utilized to determine the appropriate curing time based on test data obtained from baseline tests performed under simulated conditions in a soil cell apparatus. A computer program may be utilized such that upon entering the type of resin, the lowest recorded temperature of the structure, and the initial resin temperature, a cure schedule is supplied.Type: ApplicationFiled: July 13, 2012Publication date: January 16, 2014Applicant: LMK ENTERPRISES, INC.Inventor: Larry W. Kiest, JR.

Patent number: 8589134Abstract: A method and system for monitoring lens material residence within a conduit to improve the quality of molded products by reducing defects arising from entrapped lens material. According to the method a finite element mesh representative of a conduit is stored in a digital storage device. A simulation is run on a digital computer in which one type of lens material sequentially flows through the conduit in discrete batches temporal history of the batches within the conduit is tracked. The simulation is useful for analyzing material delivery conduits in injection molding and casting systems, for example, for lens manufacturing. According to the system, a digital storage device stores a finite element mesh representative of a conduit. A digital computer is coupled to the digital storage device for executing a set of instructions to run a simulation and track the temporal history of the batches within the conduit.Type: GrantFiled: February 11, 2011Date of Patent: November 19, 2013Assignee: Gentex Optics, Inc.Inventors: Séverine Tisné, Paresh Kitchloo
