Abstract: A system of fluid sterilization of fluid of vessel is provided, such as sterilization of ballast water for a water vessel. The system incorporates a heating section to heat pressurized fluid above prescribed thresholds for temperature, pressure, and duration (e.g., dwell time) to achieve desired levels of sterilization, including a heat exchanger to both (a) preheat fluid prior to entering the heating section and (b) cool outflow of the heating apparatus, in which fluid travels through the apparatus by operating valves forward and aft of the heating section in a controlled sequence to facilitate flow through the system while maintaining prescribed pressure and temperature profiles. The system operates within prescribed ranges of pressure and temperature to achieve the desired level of sterilization without need of maintaining a fixed temperature or a fixed pressure within any portion of the system, including the heating section.

Abstract: A rail alignment tool for aligning a rail segment of a railroad track positioned on a plurality of railroad ties is provided. The rail alignment tool includes a first side member and a second side member. The first side member includes first and second adjustment arms, and a first connecting member between the adjustment arms. The adjustment arms are positioned on opposite sides of a railroad tie. The second side member receives the adjustment arms and includes a second connecting member. At least one of the side members includes a first adjustment member that extends from the first and/or second connecting members in a first direction substantially perpendicular to a longitudinal axis of the rail segment. The adjustment arms engage a bottom surface of the rail segment and move the rail segment away from the railroad tie when the first adjustment member is extended.

Abstract: The present invention provides a resilient and tough, but flexible protective cover that hugs and squeezes various types of moving items without the need for any external securing means such as tape, rope, straps, large rubber bands, plastic, etc. The protective cover prevents damage to items that might occur during the course of moving. It eliminates, among other types of damage, scuffs, scrapes, dents, and scratches that could happen when items are being moved. While the protective cover is “hugging” the items, it also keeps items with moving components such as desks, dressers, cabinets, and appliances, in place by preventing shifting or movement of the moving components.

Abstract: A mixer is disclosed for use in a reductant dosing system. The mixer may have an impingement floor located within an intended fluid injection path and generally parallel with a flow direction through the mixer. The mixer may also have a first side wall connected along a lengthwise edge of the impingement floor, a second side wall connected along an opposing lengthwise edge of the impingement floor, and a plurality of shelves extending between the first and second side walls. The plurality of shelves each may include a plurality of vanes that promote mixing of an injected fluid. One or more of the plurality of shelves may extend different distances upstream opposite the flow direction.

Abstract: An antenna subsystem having advantageous characteristics for single channel monopulse tracking applications is described. The antenna subsystem may include an array of wave guides such as a square array of four wave guides operating in a monopulse tracking operating frequency band. A single aperture horn may be connected with the array such that one or more wave guide geometry transitions deliberately generates higher order modes. The single aperture horn may be configured such that the dominant mode and the higher order modes combine to generate a corresponding radiation pattern having an enhanced symmetry and/or uniformity. A wave guide circuit may be coupled with the array and configured to generate one or more signals usable to track a moving target such as an elevation error tracking signal and an azimuth error tracking signal.

Abstract: Embodiments herein provide an apparatus, program product, and method that enable a group of users to prepare creative documents individually while working in a shared collective environment. Embodiments herein provide direct visual feedback of the work related to the documents, being performed by users in the group. As each user makes edits to their document, the edits made by the user are communicated with a collaboration manager. The collaboration manager incorporates the edits into the document and displays a preview of the edited document to the active members of the collaboration group. The preview may be displayed in a window along with the current design window of each user. There may also be an alternate means of communication between the users of the collaboration group displayed.
