Static Electrical Clearance is defined as the minimum permissible clearance distance between live parts of either a vehicle Pantograph or the OCS, and Grounded parts of either a vehicle or adjacent fixed structure, while the vehicle is stationary.Īt concrete or masonry overhead structures, where the structure above Energized OCS conductors or Feeders is within the Overhead Contact System Zone and Pantograph Zone (Figure 5-1), metallic flash plates shall be installed above the conductors.Ī solid grooved, bare aerial, overhead electrical conductor of an Overhead Contact System that is suspended above the rail vehicles and which supplies the electrically powered vehicles with electrical energy through roof-mounted current collection equipment ( Pantograph) and with which the current collectors make direct electrical contact. Negative space could be called white space - see the below V for one example of a way to make the VOID pantograph in a fakey way - when done from completely original art with solid fills the final product is printed with two different line screens the non-void art would be printed at a nominal screen value (say 150 l.p.i.) the VOID art will. When photocopied by a color copier, the word 'VOID' appears on the copied document. Pantograph bouncing shall not adversely affect the propulsion equipment. Answer (1 of 2): From Void Pantograph Glossary Term: Void Pantograph: A pantograph screen that has the word 'VOID' hidden in it, created by using special screens and background designs. Almost impossible and costs several thousands to create. This would act as a deterrent against colour photocopy or scanned colour images of a cheque. Would take a lot of engineering to seperately mount the oak covers, currently mounted to the lights, and to engineer a pantograph that will be fighting gravity while in the 'up' position.
How to remove void pantograph manual#
Pantograph shall be graduated to enable manual measurement of stagger on either side of track center.Ĭopy Void Pantograph - the word “void” appears when the document is copied. Pantograph with hidden / embedded VOID feature shall be included in the cheques. Just have to re-hinge the oak panels for top covers, and make a pantograph system and platform to mount the lights.
The vertical distance by which the Overhead Contact System is raised during the passage of a Pantograph.Ĭhebicheff and Robert Mechanisms and straight line motion, Pantograph.
variety of chemical solvents used to remove information from documents.
For example, to perform a 2π phase modulation at wavelength λ =5 μm, a device has to produce 5 μm optical path delay.Īn arrangement of insulators and Grounded or non-Energized wires or insulated overlaps, forming a neutral section, which is located between two sections of catenary that are fed from different phases or at different frequencies or voltages, under which a Pantograph may pass without shorting or bridging the phases, frequencies or voltages. ODT Void Pantograph - Background designs or screens which expose a hidden VOID.
