Abstract: Systems and methods for reducing NOx and CO emissions in a natural draft heater are disclosed. For example, the disclosure provides embodiments of systems and methods for controlling a draft value within a heater shell to deliver an amount of excess air to a burner to thereby maintain at least one of NOx emissions not exceeding 0.025 lb/MMBtu (HHV) and CO emissions not exceeding 0.01 lb/MMBtu (HHV) in a natural draft heater.

Abstract: Systems and methods for insulating vessels are disclosed. In one or more embodiments, the disclosure provides a vessel insulation system (e.g., for use with a reactor or pressure vessel), which includes a floating ring sized to circumscribe a top nozzle of a vessel; a plurality of straps connected to the floating ring, the plurality of straps extending downward from the floating ring and being positioned to run along a length of the outer shell of the vessel; and a plurality of segmented rings positioned to circumscribe the outer shell of the vessel and connected to the plurality of straps. The plurality of segmented rings is configured to support an insulation material circumscribing the outer shell of the vessel, which can provide effective securement of the insulation material around the outer shell without welding components on the vessel to secure the insulation material.

Abstract: A parking-assist curb that helps a driver park a vehicle at a desired spot, such as in a residential garage. The vehicle's wheel(s) abut the parking-assist curb, and the abutment serves as a signal to the driver to put the vehicle in park. The parking-assist curb has a body with an opening, and has a plug inserted into the opening. A ballast mater can fill an interior of the body.

Abstract: A clothing belt assembly includes a first belt band segment, a second belt band segment, and a clothing belt connector. The clothing belt connector connects the first and second belt band segments together. The clothing belt connector has one or more connector plate(s).

Abstract: A structure is provided that applies support to wiring such as heat trace wiring to the joints and elbows of a marine arm allowing enough flexibility to avoid significant friction in the wiring while accommodating movement of the joints. A removable insulation blanket having internal retention members of wire positioning is wrapped around the joints of the marine arm and the wiring is looped outside the insulation blanket and over the joints to prevent unnecessary friction rubbing of the wiring due to joint movement.

Abstract: This drop tube loading arm assembly is adaptable for loading asphalt into tank trailers at marketing terminals. The telescoping drop tube employs guides made of steel rollers of polymers such as fluorocarbon polymers and aluminum. The guides are located in the annular space between the tubes in combination with increased radial clearance between the tubes or sleeves and in combination with protection for the overfill probe. With the addition of vapor control systems and overfill protection probes, the telescoping drop loading spouts are less susceptible to cold weather sticking problems.

Abstract: The present invention involves tomato plants (Lycopersicon esculentum) that are resistant to the tomato strain of P. infestans races 0 and 1. Lycopersicon pimpinellifolium plants which are resistant to the tomato strain of P. infestans races 0 and 1 are used to construct the tomato plants of the present invention. The preferred Lycopersicon pimpinellifolium used in the present invention is designated as LA 2533.

Abstract: Apparatus for directionally controlling the movement of high velocity air in relation to a work surface including a mobile support frame, a jet engine having an elongate tubular housing attached to the support frame, an air intake at one axial extremity of the tubular housing, a tail pipe at the other axial extremity of the tubular housing, an intake duct attached to the air intake, and an exhaust duct mounted proximate the tail pipe for directing high velocity air into impingement with the work surface.
