I'm no brass instrument, but rotary valves are used for several instruments. French horns all seem to have them. They're pretty common on tubas as well. There are even some rotary valve trumpets out there. I don't know, though, anything about the advantages and/or disadvantages of rotary valves as opposed to the piston valves that seem to be more common for most brass instruments.
There are many brass instruments that can have rotary valves instead of piston valves. The most common brass instrument in a band to have rotary valves is the french horn. However, rotary valves can be found on trumpets, trombones, flugelhorns, and tubas as well.
The French horn (:
French horn, rotary valve trumpet, tuba
this is why i came here ( it is the basson tho)
Like most instruments, the tuba evolved over a period of time, so it depends on exactly where you want to freeze-frame the process. To me, a tuba isn't a tuba unless it is a good-sized bass instrument made of brass, with a cup mouthpiece and valves, a large bore that expands throughout the length of the tube, and pitched to play well below the trombones and other brass. The first documented instrument like this is the Bass-Tuba built by Johann Gottfried Moritz in 1835, to the specifications of Wilhelm Wieprecht. It was pitched in F, with five short-action piston valves, making it quite comparable to modern instruments except for its relatively small bore and small bell. Moritz was an instrument maker in Berlin, and Wieprecht was a bandleader in the Prussian army (later director of all their military music), so this instrument's origin was solidly German and rooted in the military band tradition. Wieprecht wanted a bass instrument that could match the power of the other brass instruments, especially in an outdoor setting. The French made a contribution here as well, however, through the bass member of the "saxhorn" family, another group of instruments developed by Adolph Sax in the 1840s.

Most trombones are built in B-flat.
bullhorn
The biggest standard string instrument is a double bass.The largest ever built (in 1850) was called an octobass, a giant 3-stringed double bass.

First of all Brass doesn't corrode and it does not magnetize. Next the reason it is recorded on a brass plaque is to show record of where the ship was built and to provide a permanent hull # and year it was built or commissioned.

Because - when Colossus was built (in 1943), microchips had yet to be invented ! Microchips replaced valves and transistors in newer computers.

Barometer is an instrument used to measure atmospheric pressure.The first barometer was built by Francis Bacon. Later in 1644, Evangelista Torricelli, built the first instrument with mercury.

As far as I know, all small blocks have adjustable valves. Definitely all small blocks built before the LT1 and LS1.
