Continental's original business consisted only of packers' cans for fruits and vegetables. Given the seasonal nature of this work, the company expanded into general canning in 1912. By 1913 the company had acquired all of the interests of a New Jersey corporation also called Continental Can Co., as well as the Export & Domestic Can Co. and the ...
Typically the grating period is the same size as the Bragg wavelength, as shown above. For a grating that reflects at 1,500 nm, the grating period is 500 nm, using a refractive index of 1.5. Longer periods can be used to achieve much broader responses than are possible with a standard FBG. These gratings are called long-period fiber grating ...
Graters produce shreds that are thinner at the ends than the middle. This allows the grated material to melt or cook in a different manner than the shreds of mostly uniform thickness produced by the grating blade of a food processor. Hand-grated potatoes, for example, melt together more easily in a potato pancake than food-processed potato shreds.
Industrial canning machines used for mass-producing canned salmon in 1917. Canning is a method of food preservation in which food is processed and sealed in an airtight container (jars like Mason jars, and steel and tin cans).
Time-resolved simulation of a pulse reflecting from a Bragg mirror. A distributed Bragg reflector (DBR) is a reflector used in waveguides, such as optical fibers.It is a structure formed from multiple layers of alternating materials with different refractive index, or by periodic variation of some characteristic (such as height) of a dielectric waveguide, resulting in periodic variation in the ...
Pressure canning is the only safe home canning method for meats and low-acid foods. This method uses a pressure canner — similar to, but heavier than, a pressure cooker . A small amount of water is placed in the pressure canner and it is turned to steam, which without pressure would be 212 °F (100 °C), but under pressure is raised to 240 ...
A cotton picker at work. The first successful models were introduced in the mid-1940s and each could do the work of 50 hand pickers. Mechanised agriculture or agricultural mechanization is the use of machinery and equipment, ranging from simple and basic hand tools to more sophisticated, motorized equipment and machinery, to perform agricultural operations.

Vegetable peeler Removes the outer layer or skin of a vegetable. Pepper mill: Burr mill, burr grinder, pepper grinder: Grinds peppercorns into smaller pepper flakes or powder. Pie bird: Pie vent, pie funnel: Allows heat and steam to escape, preventing the pie from leaking or boiling over. Pizza cutter: Pizza slicer: Cuts pizzas into more ...
