Reed College
Reed College is a private liberal arts college in Portland, Oregon. Founded in 1908, Reed is a residential college with a campus in the Eastmoreland neighborhood, with Tudor-Gothic style architecture, and a forested canyon nature preserve at its center. Referred to as one of "the most intellectual colleges in the country", Reed is known for its mandatory first-year humanities program, senior thesis, progressive politics, de-emphasis on grades, academic rigor, grade deflation, and unusually high proportion of graduates who go on to earn doctorates and other postgraduate degrees. The college has many prominent alumni, including over a hundred Fulbright Scholars, 67 Watson Fellows, and three Churchill Scholars; its 32 Rhodes Scholars are the second-highest count for a liberal arts college. Reed is ranked fourth in the United States for all postsecondary institutions for the percentage of its graduates who go on to earn a Ph.D., after Caltech, Harvey Mudd, and Swarthmore Colleg ...

Reed Relay
A reed relay is a type of relay that uses an electromagnet to control one or more reed switches. The contacts are of magnetic material and the electromagnet acts directly on them without requiring an armature to move them. Sealed in a long, narrow glass tube, the contacts are protected from corrosion. The glass envelope may contain multiple reed switches or multiple reed switches can be inserted into a single bobbin and actuate simultaneously. Reed switches have been manufactured since the 1930s. Compared with armature-based relays, reed relays can switch much faster, as the moving parts are small and lightweight, although switch bounce is still present. Also, they require less operating power and have lower contact capacitance. Their current handling capacity is limited but, with appropriate contact materials, they are suitable for "dry" switching applications. They are mechanically simple, making for reliability and long life. Memory device A few million reed relays were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reed Receiver
A reed receiver or tuned reed receiver (US) was a form of multi-channel signal decoder used for early radio control systems. It uses a simple electromechanical device or '' 'resonant reed' '' to demodulate the signal, in effect a receive-only modem. The encoding used is a simple form of frequency-shift keying. These decoders appeared in the 1950s and were used into the early 1970s. Early transistor systems were in use in parallel to them, but they were finally displaced by the appearance of affordable digital proportional systems, based on early integrated circuits. These had the advantage of proportional control. Operation The decoder of the reed receiver is based on the 'resonant reed' unit. This comprises a number of vibrating metal reeds, each one having a tuned vibration frequency like a tuning fork. These reeds are manufactured from a single tapered sheet of iron or steel, giving a comb of reeds of varying length. This resembles the comb used to sound musical notes in a m ...

Reed (weaving)
A reed is part of a weaving loom, and resembles a comb. It is used to separate and space the warp threads, to guide the shuttle's motion across the loom, and to push the weft threads into place."Reed." ''The Oxford English Dictionary''. 2nd ed. 1989.1911 Encyclopædia Britannica The reed is securely held by the beater, and consists of a frame with many vertical slits. Floor looms and mechanized looms both use a beater with a reed, whereas Inkle weaving and tablet weaving do not use reeds. History Modern reeds are made by placing flattened strips of wire (made of carbon or stainless steel) between two half round ribs of wood, and binding the whole together with tarred string. Historically, reeds were made of reed or split cane. The split cane was then bound between ribs of wood in the same manner as wire is now. In 1738, John Kay replaced split cane with flattened iron or brass wire, and the change was quickly adopted. To make a reed, wire is flattened to a uniform thickn ...

Reed Valve
Reed valves are a type of check valve which restrict the flow of fluids to a single direction, opening and closing under changing pressure on each face. Modern versions often consist of flexible metal or composite materials (fiberglass or carbon fiber). Applications Traditional Reed valves, normally a leather flap covering a hole, are amongst the earliest form of automatic flow control for liquids and gases. They have been used for thousands of years in water pumps and for hundreds of years in bellows for high-temperature forges and musical instruments such as church organs and accordions. In nature, heart valves operate in a somewhat similar fashion. Pumps Reed valves are used in some reciprocating compressor designs, and in the pumping element of some musical instruments, large and small. Two-stroke engines Reed valves are commonly used in high-performance versions of the two-stroke engine, where they control the fuel-air mixture admitted to the cylinder. As the piston ri ...

Reed Pen
A reed pen ( grc-gre, κάλαμοι '; singular ') is a writing implement made by cutting and shaping a single reed straw or length of bamboo. History and manufacture Reed pens with regular features such as a split nib have been found in Ancient Egyptian sites dating from the 4th century BC. Reed pens were used for writing on papyrus, and were the most common writing implement in antiquity. In Mesopotamia and Sumer, reed pens were used by pressing the tips into clay tablets to create written records, using cuneiform. To make a reed pen, scribes would take an undamaged piece of reed about 20 cm, and leave the end that would be cut into point in water for some time. This ensured that the pen would not splinter when cut. They crafted a series of cuts that would cut the nib of the pen until it was flat enough, and pointed. The pointed end was then cut off, not too far from the point, to form a squared end suitable for writing. At the end they would start the split, which would ac ...
