Abstract:
A method for recovering tallow from food or animal processing wastewater includes adding a flocculant to the wastewater to agglomerate suspended fats, oil and grease particles in the wastewater, separating solid waste materials from the wastewater and processing the solid waste materials to recover tallow. The flocculant includes polyacrylamide or an acrylamide copolymer. A process for separating fats, oil and grease from food or animal processing wastewater is also provided.
Abstract:
A method for manufacturing a rotor blade panel of a wind turbine includes placing a mold of the rotor blade panel relative to a computer numeric control (CNC) device. The method also includes forming one or more fiber-reinforced outer skins in the mold. The method also includes printing and depositing, via the CNC device, printing and depositing, via the CNC device, a plurality of rib members that intersect to form at least one three-dimensional (3-D) reinforcement grid structure onto an inner surface of the one or more fiber-reinforced outer skins before the one or more fiber-reinforced outer skins have cooled from forming. Further, the grid structure bonds to the fiber-reinforced outer skin(s) as the structure is deposited. In addition, the plurality of rib members include, at least, a first rib member extending in a first direction and a second rib member extending in a different, second direction. Moreover, the first rib member has a varying height along a length thereof.
Abstract:
A system includes one or more tools, sensors, or both configured to obtain data related to the one or more pipelines, wherein the data is ultrasonic data, electromagnetic data, or both, and a cloud-based computing system including at least one processor that receives the data from the one or more tools, sensors, or both, performs analysis to generate a virtual structural model of the one or more pipelines based on the data, determines one or more states of the one or more pipelines using the virtual structural model and determines whether to take one or more actions when the one or more states indicate that the one or more pipelines violate a threshold operation boundary.
Abstract:
A control method for controlling movement of an off-highway vehicle comprises acquiring a plurality of actual train speed measurements from at least one sensor during a journey, and acquiriing a train power parameter corresponding to each of the plurality of actual train speed measurements. A plurality of resistance parameters are estimated or otherwise determined from the plurality of actual train speed measurements and the corresponding train power parameters. Movement of the off-highway vehicle (e.g., throttle commands) is based at least in part on the plurality of resistance parameters, which may be incorporated into a vehicle operation model and/or route plan according to which the vehicle is controlled.
Abstract:
A method for managing tax audit (TA) information (92) for a business entity using a server system (12) is provided. The server system is coupled to a centralized database (20) and at least one client system (14). The method includes receiving at the server system TA information from the client system, storing TA information received at the server system in the centralized database, tracking TA information stored in the centralized database, updating the centralized database periodically with newly received TA information to maintain TA information, and providing TA information in response to an inquiry.
Abstract:
A coil assembly includes a cylindrical ferrite core having a top end, a bottom end, an inner opening extending from the top and to the bottom end, a cylindrical outer surface, and a stepped portion formed at the bottom end, where the stepped portion extends past the outer surface of the cylindrical core. A first high dielectric material is located over at least a substantial portion of the surface of the cylindrical core by use of a coating process. A length of conductive wire is wound around the first high dielectric material located over the outer surface of the cylindrical ferrite core. The winding of the wire around the core forms a coil having a first end and a second end. A second high dielectric material is then located over the coil, not including the first end and second ends. A coil holder is formed including a base portion having a base opening formed substantially at a centered area of the coiled holder. The base opening is sufficiently sized to provide a passageway to the inner opening of the ferrite core. A plurality of snap-fit fingers extending from the base portion and engaging the step portion of the cylindrical ferrite core. By this construction, the core is locked into engagement with the coil holder.
Abstract:
A system and method for testing a control system is disclosed. The control system includes a field device located in one area and a controller located in a different area. A mobile application running on a mobile computing device is used by a technician to test the control system. Because both the mobile computing device and the controller are coupled to a cloud computing system, the technician may interface with the controller while located at the field device. This remote access to the controller allows a single technician to test the control system by interfacing with the controller and the field device simultaneously. In addition, the mobile application may retrieve data from the cloud computing system to facilitate testing and may transmit test results to the cloud for storage. Others having access to the stored results may view the progress and results of the testing.
Abstract:
A knowledge-based driver is provided for powering a solid-state light source with a constant current, including a memory that stores lumens per amp and volts per amp performance characterizations of the light source over time, and a controller that operates in a test mode to estimate the light source degradation based on voltage feedback obtained at a predetermined test current value, and to adjust the drive current in normal operating mode according to the estimated device degradation to implement constant lumens control without external optical feedback components.
Abstract:
A hybrid bumper system (10) includes a hollow reinforcing metallic beam (12) and a molded engineering thermoplastic resin energy absorber (14). The energy absorber (14) further includes at least one crushable portion (15,17). The hollow metallic beam is secured in a physically stable combination with the energy absorber, thereby resulting in a solitary hybrid bumper system.
