Methods of copying handwritten letters Manifold stylographic writer, using early "carbonic paper" Letter copying book process; Mechanical processes Tracing to make accurate hand-drawn copies; Pantograph, manual device for making drawn copies without tracing, can also enlarge or reduce; Printmaking, which includes engraving and etching
Using letter copying presses, copies could be made up to twenty-four hours after a letter was written, though copies made within a few hours were best. A copying clerk would begin by counting the number of master letters to be written during the next few hours and by preparing the copying book. Suppose the clerk wanted to copy 20 one-page letters.
The name of the machine comes from producing an entire line of metal type at once, hence a line-o'-type. It was a significant improvement over the previous industry standard of letter-by-letter manual typesetting using a composing stick and shallow subdivided trays, called "cases". The Linotype machine operator enters text on a 90-character ...
The One Ring was forged by the Dark Lord Sauron during the Second Age to gain dominion over the free peoples of Middle-earth. In disguise as Annatar, or "Lord of Gifts", he aided the Elven smiths of Eregion and their leader Celebrimbor in the making of the Rings of Power. He then secretly forged the One Ring in the fires of Mount Doom. [T 1]
Letters and typographical symbols were sometimes used to create illustrations, in a precursor to ASCII art. Because changing ink color in a mimeograph could be a laborious process, involving extensively cleaning the machine or, on newer models, replacing the drum or rollers, and then running the paper through the machine a second time, some ...
tape Turing machine can be formally defined as a 7-tuple = ,,,,, , following the notation of a Turing machine: is a finite, non-empty set of tape alphabet symbols;; is the blank symbol (the only symbol allowed to occur on the tape infinitely often at any step during the computation);
It developed from urban art in the 1960s, as an alternative to the widely spread use of spray cans in the urban art scene. Tape can be used to produce a "stained glass" effect when applied to glass or plastic which is lit from behind. It can be attached to a wall to form the outline or an image, or can be shaped into three-dimensional ...
Threaded tape of an open Compact Cassette in the tape drive. The capstan is a rotating spindle used to move recording tape through the mechanism of a tape recorder.The tape is threaded between the capstan and one or more rubber-covered wheels, called pinch rollers, which press against the capstan, thus providing friction necessary for the capstan to pull the tape.
