Small horizontal bandsaws typically employ a gravity feed alone, retarded to an adjustable degree by a coil spring; on industrial models, the rate of descent is usually controlled by a hydraulic cylinder bleeding through an adjustable valve.

:: : : : It is a water tank, usually in the loft, with a ball cock, fed by mains water supply and supplying water to wash basins, baths, showers and toilets in the house by gravity feed.

While some communities can rely entirely on a gravity-fed sewage systems, Florida's flat landscape leaves liquid waste managers at the mercy of pump stations to periodically elevate wastewater by about 10 feet to provide an artificial gravity feed.

The original Gatling gun was a field weapon which used multiple rotating barrels turned by a hand crank, and firing loose ( no links or belt ) metal cartridge ammunition using a gravity feed system from a hopper.

The innovative system used a classic gravity feed, dropping per mile, or about 1 / 4 " per 100'( ~ 0.02 % ) and running into New York City through an enclosed masonry structure crossing ridges, valleys, and rivers.
46.
A direct hit by an artillery or mortar shell could cause the fuel tanks ( which were placed high in the front horns of the track frames either side of the drivers'area, to allow gravity feed ) to burst open.
47.
A common approach was to feed a carbon electrode by gravity and maintain the gap with a pair of electromagnets, one of which retracted the upper carbon after the arc was started and the second controlled a brake on the gravity feed.
48.
Other features of the machinery space were five liquid storage tanks : two large fuel oil tanks on the centre of each wing, with two day service fuel oil tanks just forward of the former, which supplied fuel to all engines by gravity feed.

The Cheslatta " worked with engineers on a proposal to pump water outof Francois Lake, run it through a water filtration system up to a water tower, and then gravity feed it to a 44-km long mainline that would serve not only their community, but also the neighbouring Skin Tyee Band and Nee Tahi Buhn Band, as well as the non-native community ."
