All About Bucket Conveyors - Types, Design, and Uses
Bucket conveyors are a popular choice for vertical conveying and find many uses in the biomass, cement, glass, mining, power generation, and paper industries to name only a few. They keep product contained in discrete units, unlike screw conveyors that homogenize the product and excel in handling abrasive, free-flowing aggregate.

Roadway Design Manual: Minimum Designs for Truck and Bus Turns
For turning roadway widths to be reasonable, a design radius of 75-ft or more is required. Where circumstances at a particular rural arterial-arterial intersection precludes the use of the WB-62 or larger design vehicle, the WB-40 may be used. Refer to Table 7-2 for radii information with respect to the design vehicle.

Pelton Wheel: Setting, Diagrams and Problem and Solutions
The pelton wheel is today the most popular impulse turbine provided in situations where the head of water is 250 m or more. Since the head of water is large, the quantity of water required to work the turbine is less. This turbine has an overall efficiency of about 80%. The turbine consists of a number of buckets (also called cups) rigidly ...

Pelton died in Oakland on March 14, 1908, and was buried in Vermilion, Ohio. The Pelton wheel uses the momentum of a water jet impinging on buckets attached to the periphery of a wheel to produce power. It is a development of the primitive, so-called "hurdy gurdy" wheel used in the California gold fields in the 19th century.
