Drafting pantograph in use Pantograph used for scaling a picture. The red shape is traced and enlarged. Pantograph 3d rendering. A pantograph (from Greek παντ- 'all, every' and γραφ- 'to write', from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical ...
Xerox was acclaimed for developing a microtext font they claimed could produce characters 1/100 of an inch tall [9] (equivalent to 0.72 points). [ 10 ] In April 2015, Videojet Technologies released their 1650 High Resolution (HR) and 1620 HR Continuous Inkjet (CIJ) printers, said to be capable of printing sub-pixel size characters as small as 0 ...
Longarm quilting is the process by which a longarm sewing machine is used to sew together a quilt top, quilt batting and quilt backing into a finished quilt.. A complete longarming system typically consists of a sewing machine head, a frame, a table with a layer of plastic (under which is placed a pantograph), and several rollers on which the fabric layers and batting are attached.
[1] Void pantographs work by exploiting the limitations and features of copying equipment. A scanner or photocopier will act as a low-pass filter on the original image, blurring edges slightly. It will also not be perfectly aligned with the directions of the document, causing aliasing. Features smaller than the resolution will also not be ...
A simple pantograph is used to translate the planar motion of one pen to the other. The pantograph consists of two complete variable parallelograms ("d" and "e" on diagram): Base parallelogram: The base parallelogram is attached to two fixed pivot points at the far side of the base plate.
One of the links is the ground or base. [1] This configuration is also called a pantograph, [2] [3] however, it is not to be confused with the parallelogram-copying linkage pantograph. The linkage can be a one-degree-of-freedom mechanism if two gears are attached to two links and are meshed together, forming a geared five-bar mechanism. [1]
For Jacquard looms, the resulting punched cards were joined together to form a paper tape, called a "chain", containing a program that, when read by a loom, directed its operation. [ 1 ] For Hollerith machines and other unit record machines the resulting punched cards contained data to be processed by those machines.
Octavo metrics compared to the folio and quarto. Octavo, a Latin word meaning "in eighth" or "for the eighth time", [1] (abbreviated 8vo, 8º, or In-8) is a technical term describing the format of a book, which refers to the size of leaves produced from folding a full sheet of paper on which multiple pages of text were printed to form the individual sections (or gatherings) of a book.
