Publication number: 20240381906Abstract: A digital pressure canner and related methods of operation that provide for improved safety and consistency during a food canning process by reducing temperature over and undershoot. The digital pressure canner includes a digital control operating with inputs from digital sensors to accurately control the canning temperature during the canning process. By reducing over and undershoot of canning temperatures, foods within the pressure canner are maintained at temperatures sufficient to kill any bacteria or microorganisms for the entire canning cycle. In order to verify operation of the digital canner at sufficient canning temperatures, mechanical safety devices, for example, a pressure relief valve can be utilized in conjunction with digital controllers and sensors to provide audible and visual feedback to a user during the canning process.Type: ApplicationFiled: May 17, 2024Publication date: November 21, 2024Inventors: James A. Hedrington, Julian Warwick

Publication number: 20230349108Abstract: A system adjusts an instantaneous turn center for a paving machine having a tow vehicle and a screed assembly towed by the tow vehicle such that no portion of the screed assembly moves backward over freshly laid pavement when the paving machine paves around a curve. The system receives an input from an operator, a sensor, and/or a database. The input includes a distance and a direction from a first vertical axis defined by a traction device of the tow vehicle on a side of the tow vehicle facing the curve, to a second adjusted vertical axis defined by a point at least as far from the first vertical axis as an outer edge of the screed assembly that touches the curve. The system receives the input, and adjusts the instantaneous turn center for the paving machine to coincide with the second adjusted vertical axis.Type: ApplicationFiled: April 28, 2022Publication date: November 2, 2023Applicant: Caterpillar Paving Products Inc.Inventors: Mathew James Hedrington, Jacob Andrew Simmer

Publication number: 20210106176Abstract: A deep fryer and related methods of frying a whole turkey in a reduced cooking oil volume. A frying basin can have a rounded profile avoiding dead spaces within the frying basin. The frying basin can include a recessed channel at a bottommost portion of the frying basin to accommodate a heating element, such that the heating element does not project above a floor of the frying basin. The deep fryer can have a rotisserie assembly for mounting and rotating the whole turkey such that only a lower half of the whole turkey is submerged within the cooking oil at any one time. The deep fryer can include a kick-stand feature that allows a user to lower and raise the rotisserie assembly including the whole turkey using only one hand such that a user need not lean over or otherwise put their hands or body above the frying basin.Type: ApplicationFiled: October 30, 2020Publication date: April 15, 2021Inventors: James A.

Patent number: 10407844Abstract: A material feed system for a paving machine includes a first optical sensor and a second optical sensor that are configured to generate data characteristic of paving material associated with corresponding ones of a left feed mechanism and a right feed mechanism of the paving machine. A controller is communicably coupled to the first optical sensor, the second optical sensor, a left conveyor, and a left auger of the left feed mechanism, and a right conveyor and a right auger of the right feed mechanism. The controller is configured to control the left material feed mechanism and the right material feed mechanism independently of each other such that the left conveyor and auger speeds are independently adjusted based on the data received from the first optical sensor and the right conveyor and auger speeds are independently adjusted based on the data received from the second optical sensor.Type: GrantFiled: April 23, 2018Date of Patent: September 10, 2019Assignee: Caterpillar Paving Products Inc.Inventors: Ryan James Nelson, Mathew James Hedrington, Toby Andrew Frelich
