Patent number: 11885290Abstract: A fuel injector includes a nozzle assembly having a nozzle case, and a concentric check assembly within the nozzle case. Transfer passages are formed in an outer check of the check assembly, and spray orifices are formed in the nozzle case. A fuel volume is formed between the outer check and an inner check, and the inner check is movable to fluidly connect the transfer passages to the fuel volume. The outer check is rotatable between a first angular orientation and a second angular orientation to fluidly connect separate sets of the transfer passages to separate sets of the spray orifices. Spray ducts are in spray path alignment with at least one of the sets of spray orifices.Type: GrantFiled: September 8, 2020Date of Patent: January 30, 2024Assignee: Caterpillar Inc.Inventors: Bobby John, Jonathan William Anders, Glen Clifford Martin

Ducted fuel injector having nested checks with non-rotating outer check and method of operating same
Patent number: 11549474Abstract: A fuel injector includes an injector housing having a nozzle assembly with a nozzle piece, and a nested check assembly of an outer check and an inner check. Spray orifices are formed in the nozzle piece in a first orifice set equipped with a first spray duct set and a second orifice set equipped with a second spray duct set. The inner check can be opened to spray fuel from the first orifice set and the outer check can be opened to spray fuel from both the first orifice set and the second orifice set. The outer check is non-rotating while the inner check can be permitted to rotate during service. Spray ducts associated with the first orifice set may have a different duct length and duct inside diameter than spray ducts associated with the second orifice set. The first orifice set may include lower-flow spray orifices and the second orifice set may include higher-flow spray orifices. Related methodology is also disclosed.Type: GrantFiled: May 24, 2021Date of Patent: January 10, 2023Assignee: Caterpillar Inc.Inventors: Glen Clifford Martin, Bobby John, Jonathan William Anders -

Publication number: 20220173149Abstract: Exemplary aspects of the present invention are directed to an imaging sensor system for beams in the 1-200 nm spectral regions. The system may include a downconverter for converting the beam to visible light, optical filter elements, and relay optics for directing the visible light to the imaging detector. The relay optics convey the image and/or optical beam profile intensity to a 2-D imaging array such as CMOS, CCD (or other imaging detector device). The system can be used in a vacuum or in ambient non-vacuum conditions which may include a purged environment.Type: ApplicationFiled: December 2, 2021Publication date: June 2, 2022Inventors: William C. Fricke, Mike Ganopoulos, Clifford A. Martin, John K. Wilson

Publication number: 20220170853Abstract: Exemplary aspects of the present invention are directed to a sensor that uses the spectral sensitivity of detectors, the spectral properties of optical filters, and mathematical addition and or subtraction to isolate the desired spectral band. The sensor includes a downconverter member for converting the high energy beam to easily detectable visible or NIR light, and optical filter elements and relay optics for directing the visible light to the sensing members. The sensing members transmit an electronic signal proportional to the power of the light in the passband to amplifiers wherein multiple sensing members convey optical power of selected wavelength bands through an amplifier to a microprocessor with an algorithm to determine the power in the desired band of interest and then to a displaying member. The system may be used in a vacuum, in ambient non-vacuum conditions or a purged environment.Type: ApplicationFiled: December 2, 2021Publication date: June 2, 2022Inventors: William C. Fricke, Mike Ganopoulos, Clifford A. Martin, John K. Wilson

Patent number: 10463034Abstract: A fishing rod holder consists of a first panel, a second panel, a plurality of connecting members, a first strap portion, and a second strap portion. The plurality of connecting members is positioned in between the first panel and the second panel. The spacing between each of the plurality of connecting members allows a user to position a fishing rod handle in between an arbitrary connecting member and an adjacent connecting member selected from the plurality of connecting members. Since the plurality of connecting members is radially positioned, the fishing rod can be mounted at a preferred angle. The first strap portion and the second strap portion are used for attaching purposes. When the apparatus is being used with an external weighted object, the first strap portion and the second strap portion are wrapped around the external weighted object.Type: GrantFiled: May 8, 2018Date of Patent: November 5, 2019Inventors: Garry Roy Dintheer, Brad Clifford Martin
