Abstract: A device for retaining a solid sorbent includes a frame having a first rigid frame portion and a second rigid frame portion, and a non-rigid and porous structure forming one or more walls of a sorbent compartment having a selected shape, the sorbent compartment defining a volume for retaining the loose solid sorbent. The porous structure includes a first end attached to the first rigid frame portion and the porous structure is held in tension, the tension causing the porous structure to retain the selected shape when the loose solid sorbent is held in the sorbent compartment. The porous structure is held in tension by attachment to the first rigid frame portion and attachment to the second rigid frame portion, and/or by attachment to the first rigid portion and a weight of the loose solid sorbent.

Abstract: A system includes a vessel including an inlet configured to receive a thermal energy source, the vessel connected to a feeder for introducing a solid sorbent to an interior of the vessel and a collector configured to receive the solid sorbent for removal of the solid sorbent from the vessel. The system also includes a heat exchanger disposed within the vessel, the heat exchanger configured to hold the solid sorbent and facilitate a heat exchange process between the solid sorbent and the thermal energy source, and an isolation system configured to isolate the interior of the vessel during introducing the solid sorbent into the vessel and/or during removing the solid sorbent from the vessel.

Abstract: A system includes a vessel configured to receive a thermal energy source or air, and a plurality of passageways disposed in the vessel. The plurality of passageways are configured to hold a solid sorbent, the plurality of passageways causing the thermal energy source to exchange heat with the solid sorbent, or causing the air to interact with the solid sorbent. Each passageway includes a wall having a porous structure configured to prevent the solid sorbent from passing through the wall while allowing a fluid to pass through the wall.

Abstract: Described is a system for join constraints for query processing by receiving a first query directed towards a shared dataset in a data clean room; assessing the first query to identify that the one or more functions s at least a join function; determining that the first query is configured to join a first set of data from the shared dataset with a second set of data using the join function; determining that a join constraint policy is to be enforced in relation to the first query; and generating an output to the first query based on the execution of the one or more functions, the output to the first query without data values stored in the portion of the first set of data based on determining that the join constraint policy is to be enforced in relation to the first query.

Abstract: The invention discloses an automatic replacement device and an automatic replacement method for a dry-type filter module. The automatic replacement device comprises a guide rail, a moving trolley and an unpowered slide rail, the guide rails are distributed in the length direction of the dry-type paint mist intercepting area, a moving trolley is arranged on the guide rails, the moving trolley can move along the guide rails and carry the dry-type filtering module, and the unpowered sliding rail is arranged on the side of the guide rails and extends to the dry-type paint mist intercepting area.

Abstract: A sorbent bed cartridge includes an exoskeleton having an interior space configured to receive a sorbent bed, and a thickness control system to at least substantially maintain a preselected thickness of the bed. A system includes a chamber to hold one or a plurality of the cartridges, which are movable into and out of the chamber. A method of forming the cartridge includes securing the bed within the exoskeleton, and utilizing the thickness control system to maintain the preselected thickness of the bed. A cartridge includes an exoskeleton having first and second side plates and first and second end external plates, the exoskeleton configured to receive a plurality of beds in a predetermined array for carbon capture airflow, and enables movement of the cartridge and the plurality of beds contained therein into and out of a chamber sized to hold a singular or plurality of the cartridges.

Abstract: There is provided a system for wireless power transmission comprising at least one radio frequency transmitter configured to emit radio frequency waves, at least one radio frequency receiver remote from the at least one radio frequency transmitter, the at least one radio frequency receiver comprising at least one antenna configured to wirelessly receive the radio frequency waves from the at least one radio frequency transmitter, and at least one rectifier electrically coupled to the at least one antenna and configured to convert the radio frequency waves to direct current (DC) power, and at least one load electrically coupled to the at least one radio frequency receiver, the at least one load configured to receive from the at least one rectifier the DC power and to operate based thereon.

Abstract: A compression plate to be used with a slip hanger is disclosed in at least one embodiment along with embodiments of methods to prepare and use such a compression plate. The compression plate includes at least one bolt hole and includes at least one split in the at least one bolt hole.

Abstract: Various embodiments provide for managing differential privacy on a database system using one or more differential privacy policies and one or more differential privacy budgets associated with the one or more differential privacy policies.

Abstract: Various embodiments provide for using one or more differential privacy domains on a database system to execute a differentially private query on the database system.

Abstract: A system includes a chamber having a sorbent therein and forming a part of a flow loop, a gas inlet line configured to flow a fluid including gas(es), vapor(s), or a mixture thereof into the chamber such that the gas(es), vapor(s), or the mixture thereof is adsorbed by the sorbent, a gas outlet line configured to receive, from the chamber, the fluid with at least some of the gas(es), vapor(s), or the mixture thereof removed therefrom, a radio frequency (RF) system configured to provide electromagnetic energy to the sorbent within the chamber to heat the sorbent and release the gas(es), vapor(s), or the mixture thereof from the sorbent. The system is configured to induce a flow of the gas(es), vapor(s), or the mixture thereof released from the sorbent through the flow loop.
