Real Geometry: The Pantograph Overview: A pantograph, first invented in the early 1600s, was used to make exact copies before there were any ... vertical bar is for pointing (called the pointing pencil or pointer). Mount a blank sheet of …
In the seventeenth century, for the first time, artists had a device, called the pantograph, to help them mechanically copy a design on an enlarged or reduced scale. Christopher Scheiner, a German Jesuit, was responsible for designing and building the first pantograph in 1603.
The aerodynamic loads obtained for the low, normal and high configurations are interpolated, creating a force profile according to the vertical position of each …

The vertical vibration characteristics of the pantograph passing through the ice-coated catenary at different positions (support positioning position, the first dropper, and the mid-span) are shown in Figure 6, with a different ratio of catenary icing thickness to cable radius by using the increased density method. The volume of the ice layer ...

Choosing the ideal pantograph is an art that hinges on several factors. To guide your selection, here are a few quick tips: Harmonize your angles: If your quilt has many 45-degree angles, avoid overly angular designs. Likewise, a quilt laden with vertical seams may not pair well with pantographs featuring vertical lines.
He will be remembered primarily for his vertical-format single-arm pantograph engraving machine for type-making. This was not a single design, however, but a series of machines in at least two major technical revisions developed for three different type-making purposes (patrix engraving, punch engraving, and matrix engraving).
A pantograph-catenary system is very important for a high-speed electric multiple unit (EMU) train. A stable contact-point between catenary and pantograph can make the energy reach to EMU trains smoothly [1], ensuring the normal operation of EMU trains.However, when the contact-point is unstable, it is harmful to the traction power …
Then, the pantograph is enhanced by a proposed vertical enhancement operation (VEO) which is formed by intensity components Vg 1 and Vg 2, and gradient parts V u and V d. Such as: The proposed VEO is defined as: (2) Vg = Vg 1-Vg 2 + LS v V u-V d 1 + β, where S v is the sum of Gaussian weight factor in Vg 2, β is a weighting matrix to …
