The first electric-powered torque amplifier was invented in 1925 by Henry W. Nieman of the Bethlehem Steel Company of Bethlehem, Pennsylvania. [1] It was intended to allow manual control of heavy equipment; e.g., industrial cranes, artillery, etc. Vannevar Bush used Nieman's torque amplifier as part of his differential analyzer project at M.I.T in the early 1930s.

If the semiconductor is translucent, the junction becomes the source of light, thus becoming a light-emitting diode. I-V diagram for a diode. An LED begins to emit light when more than 2 or 3 volts is applied in the forward direction.
In Figure 2, a flyback diode was added in antiparallel with the solenoid. Instead of spiking to -300 V, the flyback diode only allows approximately -1.4 V of potential to be built up (-1.4 V is a combination of the forward bias of the 1N4007 diode (1.1 V) and the foot of wiring separating the diode and the solenoid [dubious – discuss]). The ...
Transmissions included a four-speed automatic and five-speed manual; the latter transmission was only offered on two-door 4WD models and was discontinued after 1995. In Mexico, the two-door Tahoe was released in 1995, called the Chevrolet Silverado, and in 1998, the four-door model was released as the Silverado 4-door.
Patrick Fyffe and George Logan devised the Hinge and Bracket act after they met performing at the Escort Club in Pimlico, London. Fyffe had already gained experience performing in his cabaret drag act as a glamorous soprano named Perri St Claire, and his character had appeared in small parts on television shows such as Z Cars and Doctor in the House, as well as the 1972 film version of Steptoe ...
One taut-line hitch is tied 15–30 cm from the aircraft and adjusted for tension, then a second taut-line hitch is tied 5–20 cm further from the aircraft and finished with a half-hitch. Wind-induced lift tends to pull the knot tighter, gust-induced oscillations tend to damp-out, and once the half hitch is undone, pushing the lower working ...
A friction hitch is a kind of knot used to attach one rope to another in a way that is easily adjusted. These knots are commonly used in climbing as part of single-rope technique , doubled-rope technique and as "ratchets" to capture progress on a moving rope, most typically in a mechanical advantage system such as a Z-drag .
