Castor (mountain)

Castor (Italian: Castore) is a mountain in the Pennine Alps on the border between Valais, Switzerland and the Aosta Valley in Italy. It is the higher of a pair of twin peaks (Zwillinge), the other being Pollux, named after the Gemini twins of Roman mythology. Castor's peak is at an elevation of 4,228 m (13,871 ft), and it lies between Breithorn and Monte Rosa. It is separated from Pollux by a pass at 3,845 m (12,615 ft), named Passo di Verra in Italian and Zwillingsjoch in German.

Ascents are usually made from the alpine hut Capanna Quintino Sella on the Italian side, by means of the Felikjoch and the long and narrow southeast ridge. From the Swiss side, ascents start from Klein Matterhorn and go by way of the Italian Mezzalama glacier and the mountain's west flank. The first ascent was made on August 23, 1861.

Castor and Pollux are also a pair of summits in Yellowstone National Park in Wyoming, USA. Located in the Absaroka Range, Castor is 3,308 m, 65 m lower than its twin.

Sieve

A sieve, or sifter, is a device for separating wanted elements from unwanted material or for characterizing the particle size distribution of a sample, typically using a woven screen such as a mesh or net or metal. The word "sift" derives from "sieve". In cooking, a sifter is used to separate and break up clumps in dry ingredients such as flour, as well as to aerate and combine them. A strainer is a form of sieve used to separate solids from liquid.

Industrial strainer

Some industrial strainers available are simplex basket strainers, duplex basket strainers, and Y strainers. Simple basket strainers are used to protect valuable or sensitive equipment in systems that are meant to be shut down temporarily. Some commonly used strainers are bell mouth strainers, foot valve strainers, basket strainers. Most processing industries (mainly pharmaceutical, coatings and liquid food industries) will opt for a self-cleaning strainer instead of a basket strainer or a simplex strainer due to limitations of simple filtration systems. The self-cleaning strainers or filters are more efficient and provide an automatic filtration solution.
