Important early machine tools included the slide rest lathe, screw-cutting lathe, turret lathe, milling machine, pattern tracing lathe ( shaper ) and metal planer, which were all in use before 1840.

* A history most specifically of Burgmaster, which specialized in turret drills ; but in telling Burgmaster's story, and that of its acquirer Houdaille, Holland provides a history of the machine tool industry in general between World War II and the 1980s that ranks with Noble's coverage of the same era ( Noble 1984 ) as a seminal history.

The TMM-1 was equipped with transmission details from the native Ya-5 truck and a ball mount for the DT tank machine gun in front of the hull, whereas the TMM-2 was equipped with an improved gear box, a steering device without clutches and a 37 mm Hotchkiss gun in the right turret.

The turret now carried the commander and the gunner who was also the radio operator.

Since the charges were less effective at larger standoffs, side and turret skirts ( known as Schürzen ) fitted to some German tanks to protect against ordinary anti-tank rifles were fortuitously found to give the jet room to disperse and hence reduce also HEAT penetration.

The turret and hull are protected with second generation Chobham armour ( also known as Dorchester ) the details of which are classified.

Initially known as Little Turret and Big turret, the 76-mm-armed tank was designated as the KV-1 Heavy Tank and the 152 mm howitzer one as KV-2 Heavy Artillery Tank.

Between the S5 and S6 helices, there is an extracellular loop ( known as ' the turret ') and ' the pore loop ', which begins and ends extracellularly but loops into the plasma membrane ; the pore loop for each of the hERG subunits in one channel face into the ion-conducting pore and are adjacent to the corresponding loops of the 3 other subunits, and together they form the selectivity filter region of the channel pore.
