Abstract: A sand handling system having, for example, one to three sand separators are configured to be operatively connected to a well and an inlet of a common dumping vessel. Advantageously, the dumping vessel has a sensor to measure an amount of sand in the dumping vessel and provide a signal to a programmable controller which is arranged to dump the dumping vessel when a specified amount of sand is in the dumping vessel. The system automates the sand handling process and also measures and records data associated with a number of flowback parameters. The data can then be used in well design to improve oil and/or gas production, lessen sand production, reduce well damage and/or equipment corrosion due to, for example, sand.

Abstract: Methods, systems, and devices are disclosed for performing mechanosynthesis, including those that involve bulk chemical preparation of tips, multiple tips for supplying feedstock, and use of sequential tips such as in a thermodynamic cascade; such features may simplify starting requirements, increase versatility, and/or reduce complexity in the mechanosynthesis equipment and/or process.

Abstract: Improved methods, systems and devices for mechanosynthesis, including those that involve the bulk chemical preparation of tips, multiple tips on a presentation surface, and multiple tips used sequentially in a thermodynamic cascade. These improvements can simplify starting requirements, improve versatility, and reduce equipment and process complexity.

Abstract: Build sequences for fabricating an atomically-precise product can be determined using computational chemistry algorithms to simulate mechanosynthetic reactions, and which may use the mechanosynthesis process conditions or equipment limitations in these simulations, to determine a set of mechanosynthetic reactions that will build an atomically-precise workpiece with a desired degree of reliability. Methods for error correction of pathological reactions or avoidance of pathological reactions are disclosed. Libraries of reactions may be used to reduce simulation requirements.

Abstract: Methods, systems, and devices are described which facilitate mechanosynthesis through the sequential use of a plurality of tips, each of which may have a different affinity for feedstock, thereby allowing tip to tip transfers which enhance system versatility and reduce equipment complexity.

Abstract: A pin-and-collet assembly, a longwall shearer comprising a ranging arm attached to a lifting bracket with such assembly, a method for the secure fastening of one piece to another, such as securely fastening the ranging arm to the lifting bracket of a longwall shearer using such assembly as a bushing, and a method for longwall mining of ore, such as trona, using such longwall shearer. This assembly is easy to install, does not have to be tightened during longwall operation of an ore panel, and is also demountable when it is time to stop the longwall mining operation and time to remove/replace the ranging arm for maintenance and/or when the end of the ore panel is reached.

Abstract: A straightening apparatus for straightening carpet prior to laying the carpet on a floor surface. The apparatus includes an entry conveyor from which carpet is unrolled and fed into a heating section. In the heating section, the carpet is heated sufficient to soften backing material on the carpet. The heated carpet is then fed into a heated straightening section where longitudinal forces are applied while the backing is still soft so that a pattern in the carpet is straightened and held in the straightened position until the carpet has cooled somewhat. The apparatus further includes a cooling section for cooling of the carpet, after which the carpet is rolled back up on an exit conveyor.
