Exposed Neon Channel Letter
Channel Letters Eye catching by standing out! A channel letter is a 3-D component in signage. Typically these are used on the store front. A “can” is made in the shape of your logo or lettering with aluminum, acrylic and internal illumination. The back side of the can is cut using the design created by our art staff and then sent to a computerized router table. This gives a precise shape for the finished “Channel”. Sides or “Returns” are then formed from aluminum strips to give the letter its depth. The returns are then fastened to the back with rivets or weld. The face for our Channel Letter is also cut utilizing our CAD/CAM router and then finished with “Trim Cap” providing a framed appearance and a mounting surface to attach to the channel. The Channel can then be lighted using Neon tubing, LED’s or Fluorescent lamps depending on the letters size, power requirements or city regulations. ________________________________________________________________ Exposed neon channel letter Another style of channel letters is made without a face or with clear faces to showcase to Neon lighting. ________________________________________________________________________ Reverse lit channel letter Yet another letter type is the Reverse Channel Letter when the face of the letter is built from aluminum or other opaque material and the lighting is exposed from the back side. This light floods the wall that the letter is mounted to. These are also called "halo effect letters". Neon 100’s of effective colors! Neon signs are made using electrified, luminous tube lights that contain neon or other gases. -
Converting Fluorescent Or Neon Signs to Energy-Efficient LED Illumination
A brighter idea? Converting fluorescent or neon signs to energy-efficient LED illumination epending on the type of your interior or exterior lighted sign, it may very Dwell pay to update its illumination to energy-efficient light-emitting diodes or LED LEDs. Thousands have found the value in retrofitting, including one nationwide chain of thousands of convenience stores. But is it right for you? Here are some considerations. LED advantages over fluorescent lighting and able to withstand shock and vibration. In contrast, neon, which is encased in glass, breaks relatively easily Some estimate that illumination via light-emitting diodes during transportation and installation, and is subject to the over fluorescent bulbs can reduce sign maintenance and same hazards of wind and weather as fluorescent bulbs. energy costs by up to 80 percent. Disposal, too, may be a concern. Neon signs contain Begin by considering the expenses of repairs.

Lilian Tone | William Kentridge | Stereoscope
Lilian Tone | William Kentridge | Stereoscope William Kentridge: Stereoscope Lilian Tone The filmed drawings, or drawn films, of William Kentridge inhabit a curious state of suspension between static to time-based, from stillness to movement. These "drawings in motion" undergo constant change and constant redefinition, while the projection of their luscious charcoal surfaces somehow retains an almost tangible tactility. Smoky grounds and rough-hewn marks morph into an incessant, though not seamless, flow of free association that evokes the fleeting hypnagogic images that precede sleep. Bodies melt into landscape; a cat turns into a typewriter, into a reel-to-reel recorder, into a bomb; full becomes void with the sweep of a sleeve. The allure of Kentridge's animations lies in their unequivocal reliance on the continuing present, in the uncanny sense of artistic creation and audience reception happening at once. Kentridge's films owe their distinctive appearance to the artist's home-made animation technique, which he describes as "stone-age filmmaking." Each of his film-related drawings represents the last in a series of states produced by successive marks and erasures that, operating on the limits of discernibility, are permanently on the verge of metamorphosis. The animations are painstakingly built by photographing each transitory state, as traces accumulate on the paper surface, each final drawing a palimpsest containing the memory of a sequence. The result is a projected charcoal drawing where the line unfolds mysteriously on the screen, with a will of its own, the artist's hand unseen. In the 1950s, filmmakers Stan van der Beek and Robert Breer's time paintings sought to document the creation of paintings on camera. -

Plasma Display Documentation
Plasma Displays & Inert Gas Discharge Tubes (IGDT) By: William J. Boucher mailto:[email protected], http://www.mnsi.net/~boucher/index.htm Created: July 24, 1999, Revised: Aug. 23, 2000 Foreword: I learned about plasma displays many years ago when I was intensely fascinated with the genius of Nikola Tesla. My personal fascination with plasma filaments began when I saw such things in sci-fi movies. I had always assumed it was some sort of special effect, but when I saw the movie My Science Project, which featured a large portable and obviously real display, my interest peaked. I started reading about them at every opportunity but detailed theory was really hard to come by, until I found out about Nikola Tesla. He invented the inert gas discharge tube (IGDT), high voltage power supplies, electromechanical machines of every type and practically everything else that has rushed the human race into the space age in just a single century. About 10 years ago, I built my first plasma display based on what I'd learned from Tesla’s work. I used to take it to mall shows and schools and such to show it off. There was always a line-up to see it. I loved it. A couple years after that, you could buy several models in stores. The most popular being Rabbitt Industry’s Eye of the Storm, which sold first in the Consumers chain stores. Unfortunately, neither that store nor the product still exists. Radio Shack still sells a small one, but it's pretty lame compared to mine because it is quite small and relatively weak. -
Chapter 14 Yards and Terminals1
CHAPTER 14 YARDS AND TERMINALS1 FOREWORD This chapter deals with the engineering and economic problems of location, design, construction and operation of yards and terminals used in railway service. Such problems are substantially the same whether railway's ownership and use is to be individual or joint. The location and arrangement of the yard or terminal as a whole should permit the most convenient and economical access to it of the tributary lines of railway, and the location, design and capacity of the several facilities or components within said yard or terminal should be such as to handle the tributary traffic expeditiously and economically and to serve the public and customer conveniently. In the design of new yards and terminals, the retention of existing railway routes and facilities may seem desirable from the standpoint of initial expenditure or first cost, but may prove to be extravagant from the standpoint of operating costs and efficiency. A true economic balance should be achieved, keeping in mind possible future trends and changes in traffic criteria, as to volume, intensity, direction and character. Although this chapter contemplates the establishment of entirely new facilities, the recommendations therein will apply equally in the rearrangement, modernization, enlargement or consolidation of existing yards and terminals and related facilities. Part 1, Generalities through Part 4, Specialized Freight Terminals include specific and detailed recommendations relative to the handling of freight, regardless of the type of commodity or merchandise, at the originating, intermediate and destination points. Part 5, Locomotive Facilities and Part 6, Passenger Facilities relate to locomotive and passenger facilities, respectively. -

Railcar Puzzle and Commodity Matching Game
NURail Project ID: NURail2014-UIUC-E09 Guidebook for Railway-themed K-12 STEM Outreach Activities By C. Tyler Dick, Ph.D., P.E. Lecturer and Principal Research Engineer Rail Transportation and Engineering Center (RailTEC) University of Illinois at Urbana-Champaign [email protected] Lee Evans Graduate Research Assistant Rail Transportation and Engineering Center (RailTEC) University of Illinois at Urbana-Champaign [email protected] 23-12-2020 Grant Number: DTRT13-G-UTC52 (Grant 2) Guidebook for Railway‐themed K‐12 STEM Outreach Activities Introduction Welcome to the Guidebook for Railway‐themed K‐12 STEM Outreach Activities! Inside, you will find descriptions of educational activities designed to introduce students to the railroad transportation mode through the lens of STEM (Science, Technology, Engineering, and Mathematics) concepts. Railroads have been a critical part of the global economy since the 1830s. Today, railroads haul more ton‐miles of intercity freight (one ton of freight moved one mile) than any other mode of transportation in the United States. While the railroad industry is the leader in long‐haul freight transportation, recruiting students to leadership roles in the industry is challenging. With many railroad employees approaching retirement age, the need to raise student awareness of railway industry career opportunities has never been greater. The activities in this guidebook cover a wide variety of railroad topics. The activities are intended to be hands‐on to provide students with knowledge through experiential learning that also increases their awareness of railway transportation technology. Although the following chapters provide a step‐by‐step guide to each activity, we encourage you to experiment with modifications to each activity and to create your own activities on other facets of the railroad industry and STEM topics.
