Abstract: An industrial automation controller includes a housing with a forced convection chamber. First and second fans are releasably connected to the housing and are adapted to induce airflow through the forced convection chamber. The first and second fans are each connected to the housing by respective first and second latch systems that each include a primary latch and a secondary latch. The secondary latch imposes a time delay during removal and replacement of a fan to facilitate hot swapping of the fan with a replacement fan. A make-last/break-first contact system is provided for each fan such that the fan is shutdown in a controlled manner prior to removal of the fan from the housing. The controller monitors internal temperature and fan speed. The controller initiates, logs, and reports fault conditions based upon the monitored temperature and/or fan speed. The controller is shut down if the monitored temperature exceeds a select temperature level.

Abstract: A cloud-native global file system, in which one or more filers are associated with a volume of a versioned files system in a private, public or hybrid cloud object store, is augmented to include a rapid ransomware recovery service. Upon detecting a ransomware attack associated with one or more files or directories of the volume, read and write access to the volume is restricted. A recovery filer is then activated or designated in the cloud. A restore operation is then initiated at the recovery filter. Following completion of the restore operation, a new clean (healthy) snapshot of the volume is then created using the recovery filer For any filer other than the recovery filer, a determination is made whether the filer has completed a merge operation with respect to the new clean snapshot. If so, read and write access to the volume is re-enabled from that filer.

Abstract: A ceramic matrix composite includes a plurality of ceramic fibers and an interface coating disposed on the plurality of ceramic fibers. The interface coating includes a carbon-based layer disposed on each ceramic fiber of the plurality of ceramic fibers and a boron-nitride based layer disposed on the first carbon-based layer. The ceramic matrix composite also includes a ceramic matrix surrounding the plurality of ceramic fibers. A ceramic matrix composite and a method of forming a ceramic matrix composite component are also disclosed.

Abstract: Systems and methods of monitoring battery health in an HVAC system. The charge state of a rechargeable battery and the number of amp-hours provided to or from the rechargeable battery are monitored. The number of amp-hours provided is recorded and an end-of-life condition is detected based on the number of amp-hours provided during the charge or discharge cycle. In some constructions, the end-of-life condition is detected by comparing the number of amp-hours provided during the charge or discharge cycle to a threshold. In some constructions, the end-of-life condition is detected by calculating a rate of change of the number of amp-hours provided during a charge or discharge cycle and comparing the rate of change to a threshold.

Abstract: A cryogenic temperature control apparatus comprises a storage tank housing a quantity of cryogenic fluid, a housing defining a conditioned space, and a heat exchanger in thermal communication with the conditioned space. A first flow path fluidly connects the storage tank and the heat exchanger. A first valve is positioned along the first flow path to selectively fluidly seal the first flow path between the storage tank and the heat exchanger. A second flow path fluidly connects the storage tank and the heat exchanger. A second valve is positioned along the second flow path to selectively fluidly seal the second flow path between the storage tank and the heat exchanger.

Abstract: A transport temperature control apparatus includes a refrigeration circuit and a heat exchanger having an air inlet and an air outlet in fluid communication with a conditioned space. An evaporator coil extends through the heat exchanger between the inlet and air outlet and is fluidly connected to the refrigeration circuit. A divider defines a first portion of the evaporator coil and a second portion of the evaporator coil. A first fan is housed in the heat exchanger and is adjacent the first portion. The first fan has a first operating condition for directing air across the evaporator coil in a first direction and a first non-operating condition. A second fan is housed in the heat exchanger and is adjacent the second portion. The second fan has a second operating condition for directing air across the evaporator coil in a second direction and a second non-operating condition.

Abstract: A temperature control system having an increased heating performance. The system includes a compressor adapted to compress a fluid, a heat exchanger coupled to the compressor such that compressed fluid moves from the compressor to the heat exchanger, and a pressure regulating valve positioned between the compressor and the heat exchanger such that compressed fluid from the compressor moves through the valve before reaching the heat exchanger. The pressure-regulating valve is designed to stay in a closed position until the pressure of the fluid from the compressor reaches a desired value. By virtue of this design, the pressure of the fluid in increased, thus resulting in an increased in the temperature of the fluid. Upon reaching the desired pressure, the valve opens to allow the highly-pressurized fluid to flow to the heat exchanger.

Abstract: The process for producing a metal billet or slab which is substantially homogeneous, fine grained and free of freezing or chemical segregation, which comprises fusing the metal, e.g. titanium or a titanium alloy, by an intense heat source, e.g. a plasma torch, to provide a small molten pool of metal within a charge of the metal, which can be scrap metal such as scrap titanium or a mixture of titanium alloy scrap, master alloy and titanium sponge. The charge of metal, preferably contained in a mold car, is traversed in a substantially horizontal plane with respect to the heat source, thereby causing the small molten pool of metal to also traverse within the metal charge, and continually melting fresh charge metal adjacent to its leading edge and causing rapid freezing of the metal adjacent to the trailing edge of the small molten pool of metal as the melted charge moves away from the heat source.
