Abstract: This disclosure provides processes for reforming hydrocarbons by using a series of adiabatic reactors and catalysts, in which the catalyst(s) in at least one front or upstream catalyst bed or reactor includes a higher fluoride concentration, higher chloride concentration, or both than the respective halide concentrations in the catalysts in one or more downstream catalyst beds or reactors, which has been unexpectedly discovered to extend the useful life and/or the selectivity of the catalyst system.

Abstract: A transportable storm shelter or kit for a transportable storm shelter having a plurality of removable frames and a plurality of removable skins removably receivable on or within the removable frames and secured together by removable fasteners that are not bolted in place. A hollow tube fastener, having a hollow tube guide and a removeable pin receivable therethrough, is configured on a surface of the removable skins to hold the removable skins in assembled configuration with the removable frames. The removable skins are securable from the interior of the shelter, allowing the occupant to remove the skins from within the interior by removing the pins from the fasteners. The storm shelter provides a door with hinges that may be removed from the exterior by rescue personnel. The storm shelter is approximately the size of a garage workbench and can be sold as a kit and assembled using minimal construction skills.

Abstract: A molding tool and method for making the molding tool by additive manufacturing is provided. The molding tool includes a tool body having a tooling surface for molding a part, the tool body comprising a eutectic alloy. The method for making the molding tool by additive manufacturing includes forming a first layer of eutectic alloy, the forming comprising depositing the eutectic alloy in liquid form and then cooling for form a solid eutectic alloy; forming an additional layer of the eutectic alloy on the first layer, the forming of the additional layer comprising depositing the eutectic alloy in liquid form and then cooling to form the solid eutectic alloy; and repeating forming an additional layer of the eutectic alloy on the first layer, the forming of the additional layer comprising depositing the eutectic alloy in liquid form and then cooling to form the solid eutectic alloy, and repeating one or more times to form a structure comprising a tool body having a tooling surface.

Abstract: A reversible line blade for a rotating trimmer includes a loading section configured to be securable for rotation with a head of the rotating trimmer, a living hinge extending from the loading section, a transition section extending from the living hinge, and a cutting segment extending from the transition section. At least one of the transition section and the cutting segment has a cross-sectional shape that is configured to generate an updraft when the line blade is rotated clockwise and when the line blade is rotated counter-clockwise.

Abstract: A water heating and treatment system includes a water heater, a hot water outflow line from the water heater, and a cold water supply line to supply water to the water heater. The cold water supply line includes at least one of an anti-scale device, and a UV sanitation lamp. A mixing station supplies a temperature regulated heated water to one or multiple temperature zones. A mixing station supplies heated water to at least a first temperature zone at a first hot water temperature. The water heater, the anti-scale device, the UV sanitation lamp and the mixing station are contained in a single enclosure having at least one sliding transparent wall through which components can be viewed. A plurality of pipe connections passing through a rear panel of said single enclosure are also described.

Abstract: A water heating and treatment system with UV lamp water treatment sanitation for suppression of pathogens and undesired bacterial content in a domestic hot water system includes a water heater, and a cold water supply line to supply water to the water heater. The cold water supply line includes a UV sanitation lamp. A single or multiple temperature regulating mixing station supplies a temperature regulated heated water to one or multiple temperature zones. A three-way return water diverter valve provides a portion of a re-circulated hot water from a hot water recirculation line including a temperature sensor to the single or multiple temperature regulating mixing station and a remaining portion of the re-circulated hot water to the drain. A method for treating hot water to suppress pathogens and undesired bacterial content in a domestic hot water system is also described.

Abstract: A blade positioning system for a work machine. The system may have a blade control which has a blade position sensor, and the blade control may adjust a blade of the work machine to a fixed position relative to a wheel. The system may also have a steering control that has a wheel position sensor, and the steering control may steer the work machine. The controller may monitor the blade position sensor and the wheel position sensor to determine a present position of the blade and the wheel prior to the repositioning of the wheel, and adjust the blade position as the wheel is repositioned to maintain the fixed position of the blade relative to the wheel.

Abstract: A cutting blade for a rotating trimmer includes a loading section at a proximal end securable to the rotating trimmer, a flexible hinge section extending from the loading section, and a transition section extending from the flexible hinge section. A cutting section extends from the transition section to a distal end. The transition section and the cutting section are tapered at a taper angle toward the distal end. In some variations, a mass of the transition section is greater than a mass of the cutting section, and a center of gravity based on a mass of the cutting blade may be positioned closer to the loading section than the cutting section.

Abstract: A glider assembly for a handheld trimmer includes a glider shaft coupleable at one end with a rotating head of the handheld trimmer, and a glider plate connected to an opposite end of the glider shaft. The glider plate is part-spherical or saucer shaped and includes a concave side and a convex side. A bearing acts between the glider plate and the glider shaft. The assembly enables an operator to rest the weight of the trimmer on the ground during use while controlling a cutting height.

Abstract: A system for processing plastic waste may include a feed line, a feed fractionator, a hydrotreater, a catalytic reforming unit, a heavy oil cracker, and a steam cracker. A pyrolyzed plastics feed is separated into light, medium, and heavy hydrocarbon streams. The hydrotreater removes sulfur, and the catalytic reforming unit produces a circular aromatic-rich stream. The heavy oil cracker generates cracked streams. The steam cracker produces a circular olefin stream from a cracked stream. A system for processing plastic waste may include the feed line, the feed fractionator, the hydrotreater, a medium hydrocarbon fractionator, the catalytic reforming unit, a full-range reforming unit, the heavy oil cracker, and the steam cracker. The medium hydrocarbon fractionator produces two hydrocarbon streams. The full-range naphtha reforming unit produces a second circular aromatic-rich stream.
