  2. Process engineering - Wikipedia

    en.wikipedia.org/wiki/Process_engineering

    Process engineering is the understanding and application of the fundamental principles and laws of nature that allow humans to transform raw material and energy into products that are useful to society, at an industrial level. [1] By taking advantage of the driving forces of nature such as pressure, temperature and concentration gradients, as ...

    en.wikipedia.org/wiki/Semiconductor_device...

    During the production process wafers are often grouped into lots, which are represented by a FOUP, SMIF or a wafer cassette, which are wafer carriers. FOUPs and SMIFs can be transported in the fab between machines and equipment with an automated OHT (Overhead Hoist Transport) AMHS (Automated Material Handling System). [60]

  4. Threshing machine - Wikipedia

    en.wikipedia.org/wiki/Threshing_machine

    Threshing machine. A threshing machine in operation. A threshing machine or a thresher is a piece of farm equipment that separates grain seed from the stalks and husks. It does so by beating the plant to make the seeds fall out. Before such machines were developed, threshing was done by hand with flails: such hand threshing was very laborious ...

  5. Combine harvester - Wikipedia

    en.wikipedia.org/wiki/Combine_harvester

    The modern combine harvester, also called a combine, is a machine designed to harvest a variety of cultivated seeds. Combine harvesters are one of the most economically important labour-saving inventions, significantly reducing the fraction of the population engaged in agriculture. [1] Among the crops harvested with a combine are wheat, rice ...

  6. History of chemical engineering - Wikipedia

    Chemical engineering. Chemical engineering is a discipline that was developed out of those practicing "industrial chemistry" in the late 19th century. Before the Industrial Revolution (18th century), industrial chemicals and other consumer products such as soap were mainly produced through batch processing. Batch processing is labour-intensive ...

    v. t. e. The American system of manufacturing was a set of manufacturing methods that evolved in the 19th century. [1] The two notable features were the extensive use of interchangeable parts and mechanization for production, which resulted in more efficient use of labor compared to hand methods. The system was also known as armory practice ...

    Platt's roving frame, c. 1858. Cotton-spinning machinery is machines which process (or spin) prepared cotton roving into workable yarn or thread. [1] Such machinery can be dated back centuries. During the 18th and 19th centuries, as part of the Industrial Revolution cotton-spinning machinery was developed to bring mass production to the cotton ...

  9. Photolithography - Wikipedia

    en.wikipedia.org/wiki/Photolithography

    Photolithography. Photolithography (also known as optical lithography) is a process used in the manufacturing of integrated circuits. It involves using light to transfer a pattern onto a substrate, typically a silicon wafer. The process begins with a photosensitive material, called a photoresist, being applied to the substrate.
