Abstract: Processes and apparatuses for heating a hydrocarbon process stream, with an electric heater to provide a portion of the heat requirement necessary for a chemical reaction to occur to one of the components of the hydrocarbon process stream. The electric heater may be used between two reaction zones which are arranged on top of each other. Additionally, reaction zones may be in reactors which are arranged in a polygon.

Abstract: Electric heaters for heating a hydrocarbon process stream. The electric heater has a cavity with parallel walls which may provide a rectangular cross section to the cavity. The parallel side walls may be parallel to a longitudinal axis of the electrical heating elements which extend into the cavity to transfer heat to fluid passing there through. Various configurations and orientations of the electrical heating elements are provided.

Abstract: A circuit-cycle fault reproduction system includes a hardware processor configured to execute at least one computing cycle corresponding to a given number instructions. A cycle tracking unit is configured to identify at least one test cycle included in a range of computing cycles starting from at a start cycle and completing at an end cycle. A fail cycle detection unit is in signal communication with the cycle tracking unit. The fail cycle detection unit is configured to identify a failed cycle among the plurality of test cycles based on a cycle difference between the starting cycle and the ending cycle, and to actively modify the range of computing cycles based on a comparison between the cycle difference and a cycle difference threshold value.

Abstract: Critical path failure analysis using hardware instruction injection may include providing, by an instruction microcontroller, to a plurality of processor cores, one or more test instruction sequences, wherein the instruction microcontroller is coupled to, for each of the plurality of processor cores: a first multiplexor providing an input to an instruction queue, and a second multiplexer receiving an input from the instruction queue and providing an output to an execution pathway; performing, by the instruction microcontroller, based on one or more test instruction sequences, one or more of a scan-in last pass (SLP) analysis or a scan-in cycle offset (SCO) analysis; and determining, based on one or more of the SLP analysis or the SCO analysis, one or more of a critical instruction sequence or a critical component path associated with the plurality of processor cores.

Abstract: A rigid electrical raft has electrical conductors embedded in a rigid material. The electrical conductors transmit electrical signals through the rigid electrical raft, which may form part of an electrical system of a gas turbine engine. The rigid electrical raft also has electrical heating elements embedded therein. The electrical heating elements provide heat which may be used, for example, to prevent condensation and/or ice build-up and/or to raise the temperature of electrical components to be within a desired range.

Abstract: A rigid electrical raft is provided to a gas turbine engine via a fusible mount arrangement. The rigid electrical raft may be a part of an electrical system of the gas turbine engine, for example a part of the electrical harness. The fusible mount is arranged to break when a predetermined load is applied. The rigid electrical raft may be attached to a fan case of the engine, and the predetermined load may be that which results from a fan blade being released from the hub. This ensures that the rigid electrical raft is protected from the load.
