feed

The electrical element at the focus of a radio dish that collects the radio waves and feeds them to the receivers. The element may be a dipole connected to a transmission line, or a horn (called a feedhorn) connected to a waveguide. In both cases the physical size of the feed must be chosen to match the wavelength of the signal. A telescope capable of observing at a number of wavelengths may therefore possess a selection of feedhorns, any one of which may be moved to the focal point.

Feed

 

the relative motion of a cutting tool and workpiece on a machine tool; one of the main parameters that characterize the cutting mode during the working of articles on machine tools. Feed makes possible sequential extension of the cutting process to the entire surface being worked.

A distinction is made among continuous feed (for example, in lathes, drilling, and milling machines) and periodic feed (in planers and slotters) and between rectilinear feed (in lathes, drilling, and milling machines, and planers) and circular feed (during rotation of parts in certain grinding machines). Feed is measured in millimeters per revolution of the workpiece or tool (machine tools of the lathe group); in millimeters per double pass of the table or slide (planers); or in millimeters per minute, which is called time feed (milling machines).

Avery's speech will emphasize the many ways in which agricultural engineering has made human society more sustainable, from the no-till drills that help disarm soil erosion and the computer-controlled, low-evaporation center-pivot irrigation systems that stretch scarce water supplies, to confinement livestock systems, which save pasture land and raise feed conversion rates to save cropland too.
Positioned as an innovative alternative to traditional feed supplements, ProtiOne is a protein supplement, that when added to starter diets of weanling pigs, improves gain and feed conversion. ProtiOne was introduced into the swine industry in June 2000 and has captured two percent of the baby pig protein supplement market since then.
