Abstract: A common-mode current sensor system and method for a traction inverter of an electric hybrid vehicle. The system and method detects/reduces excess common-mode currents that can be caused by the presence of alternating current (AC)-chassis type short circuit faults at the outputs of an inverter used for driving a two or more-phased load. In an embodiment, the system detects the presence of an AC-chassis fault of any varying strength, e.g., weak, medium, hard, in respective parallel paths. The system and method can isolate a particular AC-chassis type fault to a particular phase leg of the inverter thereby obviating a need of having to shut-down and/or re-program each phase leg of the whole power supply and vehicle operation. Rather, upon detecting a chassis short, a fault signal is asserted to control shutting down of one or more inverter switches without having to shut-down the vehicle or negatively impact the vehicle status.

Abstract: A gate drive topology and gate drive power supply topology designed to allow for a single Printed Wiring Board (PWB) design to be configured for two applications. In one application, select paired locations of solder pads or connector locations in the circuitry are populated with connecting “spanning” resistors for integration within the gate driver and gate driver power supply topologies. The physical manifestation of these resistors on the PWB allows paralleled gate drive switching of corresponding power transistor devices for driving a load. A common gate-source voltage is applied to all three gates and the switching devices share dynamic switching and conduction loss. In an alternate application, the select paired locations are not populated with spanning resistors thereby rendering a circuit topology permitting independent operation independent power transistor gate driving switching operations.

Abstract: A coke drum measurement system includes a first target coupled to an upper aspect of a coke drum and a second target arranged generally perpendicular to the first target. A first optical measurement device is arranged to visualize the first target and measure a distance between the first optical measurement device and the first target. A second optical measurement device is arranged to visualize the second target and measure a distance between the second optical measurement device and the second target. A processor is electrically coupled to the first optical measurement device and the second optical measurement device. The processor receives signals from the first optical measurement device and the second optical measurement device corresponding to movement of the coke drum. The processor aggregates signals received from the first optical measurement device and the second optical measurement device to determine a total movement of the coke drum.

Abstract: A traffic door includes a door body having at least one edge and opposed faces, and an edge trim including an inner surface and an outer surface and attached to the door body to cover at least a portion of the at least one edge. The inner surface of the edge trim includes a cavity that receives the at least one edge of the door body therein and the edge trim is secured to the door body through a friction fit between the cavity and the door body. The edge trim includes reinforcement regions adjacent the cavity to increase strength in this region, and void regions away from the cavity to minimizing weight and material usage. A method of assembling a traffic door having edge trim is also disclosed.

Abstract: A universal sliding door system that is configured to facilitate installation in either a slide right to open (SRO) orientation or a slide left to open (SLO) orientation. In some embodiments, a track is attached to a header by a pivot connector that allows the track to be pivoted up or down so that the track can be easily oriented at an appropriate angle for the desired opening orientation. The header and track may also each include a first set of openings configured to allow the track to be easily installed in a SRO orientation and a second set of openings configured to allow the track to be easily installed in a SLO orientation. Other components of the door system, such as the door and the vertical casing members may also include features configured to allow the components to easily be installed in either opening orientation.

The door body may be a monolithic one-piece construction, apart from any such closure members, and optional any window and window support. The door body may be formed by rotational molding.

Abstract: A blow tube for delivering particulate material from a container thereof to a mold to form a core has a unitary, elongate body formed of resiliently elastic material which enables the body to adjust and compensate for misalignment of the container and the mold. The blow tube body has a bore having a plurality of axially spaced sections so that when the particulate material is blown through the body by compressed gas, the density of the particulate material is increased and the velocity of the gas and particle stream is increased. The elasticity of the blow tube body enables the latter to expand in the event the particulate material clogs the blow tube, thereby enabling the clog to disaglomerate.

Abstract: An arrangement in an electrical switching device for protection against electrical arcs comprises a tripping mechanism, a stationary contact carrier, a movable contact carrier, an exhaust vent, an arc runner, and an arc extinguishing barrier. The stationary contact carrier has a stationary contact mounted thereon, and the movable contact carrier has a movable contact mounted thereon. In response to an overcurrent condition, the tripping mechanism causes the movable contact carrier to rotate from a closed position to an open position, thereby generating an electrical arc. In the closed position the movable contact abuts the stationary contact, and in the open position the movable contact is separated from the stationary contact. The arc extinguishing barrier is composed of an outgassing material and is located between the stationary contact and a portion of the tripping mechanism.
