Abstract: Methods and systems are described herein for a system that enables individual users or entities to assess high-level concepts expressed in natural language by identifying quantitative evaluation criteria for evaluating the concept. For example, a query evaluation system is provided herein that receives a user's query including natural language, e.g., indicative of a higher-level concept or idea to be deployed. The system may identify quantitative evaluation criteria for evaluating the concept, perform back-testing (e.g., to see how a particular strategy would have performed in the past) and allow the user to create a specific investment portfolio that tracks the original intent of the user. The concept may be tested, and its performance evaluated before deploying it to a user portfolio.

Abstract: A system and method generate answers to user queries by providing natural language responses containing direct citations to primary sources. The system comprises a data collection pipeline that ingests, processes, and organizes data from multiple sources, and a retrieval mechanism that processes user queries, identifies relevant data, and employs a machine learning model, such as a Large Language Model (LLM), to generate natural language responses based on the retrieved data. The generated responses are augmented with direct references to the primary sources, ensuring accurate attribution and up-to-date information. This system combines the natural language capabilities of LLMs with the direct connections to primary sources provided by traditional search engines, delivering real-time, dynamic processing of resources without incurring high re-training costs.

Abstract: An adapter for a cylindrical polyethylene comprises a tubular body section, a saddle-shaped flange connected at a first end to the tubular body section, and adapted to mate with an outer surface of the cylindrical tank, the saddle-shaped flange including a bolt hole pattern having a first spacing. A circular flange connected to a second end of the tubular body section, the circular flange having a bolt hole pattern having a second spacing, wherein the first bolt hole spacing is one half the second bolt hole spacing.

Abstract: An adapter for a cylindrical polyethylene tank is disclosed comprising a tubular body section, a saddle-shaped flange connected at a first end to the tubular body section, and adapted to mate with an outer surface of the cylindrical tank, the saddle-shaped flange including a bolt hole pattern having a first spacing. A circular flange connected to a second end of the tubular body section, the circular flange having a bolt hole pattern having a second spacing, wherein the first bolt hole spacing is one half the second bolt hole spacing.

Abstract: A brine generating system is disclosed for use with an underground storage tank, the system including a main salt delivery channel that branches into two horizontal feed lines through a reducer to deliver salt under pressure to the bottom of the storage tank in a generally equal distribution along the tank floor. The salt distribution system can be combined with a water distribution system to ensure delivery of water at the location of the salt deposits along the tank floor.

Abstract: A seamless, double-walled sump is disclosed for collecting run-off materials and waste products. The sump includes a primary containment vessel and a secondary vessel, integrally molded into a single seamless unit. The sump includes a plurality of ribs that cooperate with surrounding concrete or other enclosing material to anchor the sump and prevent floating. The sump may also include a fabric outer layer that serves as an interface between the concrete and the sump to prevent corrosion.

Abstract: A venting solution to large storage tanks is disclosed wherein a manway cover is formed with a vent, eliminating the need to affix a vent to the wall of the tank and allowing standardized manway covers with different vent sizes to be applied either in a retrofit or in new tanks. The covers can be formed two at a time to increase production, and can be fitted with a larger vent than would otherwise be practical with some tank diameters.

Abstract: A bookmark for use in indicating a line, column and page in an open book has a thin, flat, rectangular body (10) over which an encircling indicator (12) or indicators can move. The cuts defining the restraining part of each indicator have inwardly curving portions at their ends providing a degree of friction to temporarily restrain each indicator in position.
