A conveyor comprising a series of closely spaced rollers set so that their crests can support articles to be conveyed. They may be power-driven, or freely revolving. Tapered rollers are used to form bends in the conveyor line.
A variable area flow meter which consists of a tapered tube of glass with a float inside that is pushed up by flow and pulled down by gravity.
A positive displacement compressor in which compression displacement is effected by the positive action of rotating elements.
A positive displacement compressor in which compression displacement is effected by the positive action of rotating elements.
A positive displacement pump that consists of a chamber containing gears, cams, screws, vanes, plungers or similar elements actuated by relative rotation of the drive shaft or casing and which has no separate inlet and outlet valves.
