A bus coupler is a device which is used to couple one bus to the other without any interruption in power supply and without creating hazardous arcs. A bus coupler is a breaker used to couple two busbars to perform maintenance on other circuit breakers associated with that busbar. It is achieved with the help of a circuit breaker and isolators.
A gladhand connector or gladhand coupler is an interlocking hose coupling fitted to hoses supplying pressurized air from a tractor unit to air brakes on a semi-trailer, [1] or from a locomotive to railway air brakes on railroad cars. [2] Gladhand connectors resemble a pair of "hands shaking" when interlocked, hence the name. [1]
Custom-built bus couplers connected the bays to one another so that the processors could reach the shared memory and the I/O devices. A 6-processor Pluribus was used as a network switch to interconnect BBN's five Tenex /"Twenex" timesharing systems along with 378 terminals on direct serial and dial-in modem lines.
At the two ends of the bus, resistors connect between the positive (high) and negative (low) signal wires either in internally terminated bus couplers or external connectorized terminators. The MIL-STD-1553B bus must be terminated at both ends to minimize the effects of signal reflections that can cause waveform distortion and disruption or ...
An interlocking system is designed so that it is impossible to display a signal to proceed unless the route to be used is proven safe. Interlocking is a safety measure designed to prevent signals and points/switches from being changed in an improper sequence. For example, interlocking would prevent a signal from being changed to indicate a ...
LockTrac 6131 ELEKTRA is an electronic interlocking system that provides the highest levels of safety and availability. The system is approved according to CENELEC standards with safety integrity level 4 ( SIL4 ) and offers basic interlocking functions, local and remote control, automatic train operation, integrated block functionality and an ...
“There’s always going to be people like me who are smiling the first time they get on the bus [to boot camp] – they don’t want to miss the war,” he said. “There will always be kids willing to fight, and they’re always going to pay this price, and there are always going to be guys like me who are saying, ‘Hey man, you don’t ...
Narrow gauge flat wagons, 750 mm (2 ft 5 + 1 ⁄ 2 in).Note the single buffer with a hook on the right side and a chain on the other. On some narrow-gauge lines in Europe, and on the Paris Metro, a simplified version of the loose-coupler is used, consisting of a single central buffer with a chain underneath.
