Abstract: Methods and systems for making ammonia are provided. The method can include heating a first compressed syngas to produce a heated first syngas. The heated first syngas and a second compressed syngas can be combined to produce a combined syngas. The combined syngas can be reacted within a first ammonia converter and a second ammonia converter to produce an ammonia product. Heat from the ammonia product can be transferred to a first heat transfer medium to produce a first cooled product and a second heat transfer medium. Heat from the first cooled product can be transferred to a third heat transfer medium to produce a second cooled product. Heat from the second cooled product can be transferred to the combined syngas to produce a third cooled product. The third cooled product can be separated to produce a purified ammonia product and a recycle gas.

Abstract: Methods and systems for making ammonia are provided. The method can include converting carbon monoxide in a first syngas to carbon dioxide to produce a shifted syngas. At least a portion of the carbon dioxide can be separated from the shifted syngas to produce a carbon dioxide-lean syngas. Carbon monoxide and/or carbon dioxide in the carbon dioxide-lean syngas can be converted to methane to produce a methanated first syngas. A second syngas can be separated to produce a purified second syngas and a waste gas. The methanated first syngas and the purified second syngas can be combined to produce an ammonia feedstock. The ammonia feedstock can have a hydrogen to nitrogen molar ratio of about 3.5:1 to about 2.5:1. At least a portion of the hydrogen and nitrogen in the ammonia feedstock can be reacted to produce an ammonia product.

Abstract: A system and method for regulating the amount of water in a battery of storage tanks for use in hydraulic fracturing. The system includes a source for the water, attached to the battery of tanks using pumps and controllable valves. Levels in the tanks are transmitted to a central processing unit, which controls the valves to govern the flow of water. Remote monitoring and control is enabled by communication between the central processing unit and a monitoring location.

Abstract: A side under-ride collision guard is described configured to be mounted on a large trailer equipped with a sliding rear axle, comprising at least two linear fixed energy absorbing beam structures mounted axially with the trailer and attached to a plurality of support members connecting the beam structures to opposing ends of the trailer's floor beams, and at least two linear telescoping beam structures axially adjustable for position with respect to the fixed beam structures. The guard diminishes the impact hazard to other roadway users that is presented by the lower axial edge(s) of the cargo compartment in the two outboard regions that exist between the trailer's protected regions, which are typically the landing legs or prime mover rear tires to the front and the trailer's sliding axle assembly to the rear of the trailer.

Abstract: A method of matching a first entity to a second entity by evaluating Boolean expressions includes identifying a set of criteria vertices for a second entity vertex by traversing a graph database in a manner constrained to fact vertices identified for the second entity. The graph database relates fact vertices to the criteria vertices by edges corresponding to Boolean expressions for satisfying criteria for matching first entities to second entities. The method additionally includes selecting one of the first entities based on the criteria vertices of the set. The method further includes matching the first entity to the second entity based on the selection.

Abstract: Systems and methods for collecting samples from a patient for diagnosis are provided. In many embodiments, the sample collection and analysis system concentrates particles emanating from a patient's cough, sneeze, or breathe in a sample for the diagnosis of a respiratory tract infection or other ailment of the patient. The sample collection and analysis system has a pre-collection assembly (that is patient interface, a collector in fluid communication with a sample reservoir that function in combination to: efficiently capture the volume of air expelled from the subject, direct the expelled air towards a sample reservoir, and separate the desired particle sizes from the expelled air into the sample reservoir.

Abstract: By law, a stand-up lift truck operator must be trained to keep both feet and legs located within an operator compartment. An exemplary operator presence detector includes multiple zones, or areas, configured to receive an operator's feet. A sensor arrangement detects the presence of the operator's feet and a logic device determines whether the operator's feet are present in the zones or areas in a predetermined configuration, such as a configuration that reinforces operator training to keep both feet in a designated area on a compartment platform. In preferred arrangements, based on whether the operator's feet are present in the zones in a predetermined configuration, at least one vehicle function is enabled or disabled which may serve to reinforce an operator's training to keep both feet and legs located within an operator's compartment.
