In the mid 1980s, Pass designed the well-reviewed Adcom GFA-555 amplifier. This was a Bipolar Junction Transistor (BJT) based design. [6] [7] Nelson also designed the GFA-5XXX MOSFET-based series of high-bias class-AB amplifiers for Adcom (i.e. -5300, -5400, -5500, -5800).
The 1500 Widelux also used different shutter speeds of 1/8, 1/60 and 1/250 of a second. The F series cover a 140 degree view, whereas the 1500 series covers a slightly wider area (150 degree view-diagonally-140 degr.horizontally). Finally, the 1500 Widelux, like most manual film cameras, has a shutter that must be cocked before the camera will ...
IHI started development work on the high bypass ratio turbofan engine in 1998, based on the low bypass ratio engine XF5-1. and the first prototype XF7-1 was tested from 2000 to 2002. The flight test XF7-10's testing started in 2002. [1]

1795 (): Boulton and Watt open their Soho Foundry, for the manufacture of steam engines; 1799 (): Richard Trevithick builds his first high-pressure engine at Dolcoath tin mine in Cornwall. 1800 (): Watt's patent expires. By this time about 450 Watt engines (totaling 7,500 hp) [13] and over 1,500 Newcomen engines have been built in the UK.
In Terminal 4 at Los Angeles International Airport, a TSA officer flagged a carry-on bag with 82 consumer-grade fireworks, three knives, two replica firearms and a canister of pepper spray.
The design was based on the Electro-Motive Diesel EMD F7 locomotive. [1] The first 11 were delivered with EMD 16-567B , 1,119 kW (1,501 hp) engines and four powered axles with the remainder having 16-567C, 1,305 kW (1,750 hp) engines and six powered axles.
