Abstract: A non-transitory computer readable storage medium may have stored thereon instructions that, when executed by an endpoint device, cause the endpoint device to perform operations including: (i) establishing, by the endpoint device, a first communication channel with an intermediary proxy server; (ii) receiving, from a computational instance and via the intermediary proxy server, a registration payload comprising a list of available proxy servers; (iii) ranking, at the endpoint device, the list of available proxy servers; (iv) selecting, by the endpoint device, a particular proxy server from the list of available proxy servers as ranked; (v) establishing, by the endpoint device, a second communication channel with the particular proxy server; and (vi) communicating, by the endpoint device, with the computational instance via the particular proxy server by utilizing the second communication channel.

Abstract: A parts catalog system is provided. The system may include a processor and a computer-readable medium operatively coupled to the processor and including a memory in which is stored a database configured to catalog collections of data associated with and identifying hardware items. The system may also include a graphical user interface (GUI) configured to display at least some of the data associated with and identifying a hardware item including. The displayed data may include a graphical representation of the hardware item. The displayed data may also include a data field integrated with the graphical representation illustrating the physical significance of the data within the data field with regard to the hardware item illustrated by the graphical representation. The data field may also be configured to accept input to designate a desired value for the data within the data field.

Abstract: A control scheme for controlling hydrogen partial pressure is provided that generally comprises a hydrogen purity analyzer that measures hydrogen purity on one or more hydroprocessing units. The hydrogen analyzer measures the purity of the treat gas, which is converted into a control signal and is transmitted to the appropriate hydroprocessing unit's purge gas controller. As hydrogen purity decreases in the hydroprocessing unit's recycle stream, the purge gas control valve opens and purges cracked gas contaminants. As hydrogen purity fluctuates, the purge gas control valve will open and close to maintain the desired purity setpoint. A programmable logic controller manages the inputs from the one or more hydroprocessing units and the signals that are transmitted to each unit's purge controller. The programmable logic controller may also be utilized to reactor hydrogen quench systems. The control of hydrogen partial pressure improves catalyst activity, hydrogen usage, and fuel efficiency.
