  • The Curious Case of U.S. Letters Patent No. 223,898
    CHAPTER 5 The Curious Case of U.S. Letters Patent No. 223,898 I have not failed. I’ve just found ten thousand ways that don’t work. —Thomas Edison ho invented the light bulb? This was the topic at hand. Technically, the litigation Wwas between the Edison Electric Light Company and the Mount Morris Electric Light Company, but everyone knew that these were subsidiaries and legal proxies for their parent companies. Even the attorneys litigating this $1 billion case called it simply Edison v. Westinghouse. The issue before them: U.S. Letters Patent No. 223,898, granted to Thomas Edison on January 27, 1880, which described the invention of an “incandescent electric lamp.” Quickly nicknamed the Light Bulb Patent by the press, it was without question the most valuable patent ever granted in the history of the United States. And George Westinghouse was accused of infringing on it. Yet, as Paul Cravath pointed out to his client George Westinghouse, even a problem so simply put might yet admit to many layers of unraveling. In fact, the question hinged on one’s precise definition of the terms involved—“who,” “in- vented,” “the,” and, most importantly, “light bulb.” The first electric lamps had actually been invented almost a cen- tury before, Paul had learned when he’d first begun to research the case. Sir Humphry Davy had publicly demonstrated early “arc lights” in 1809. By attaching a battery to two charcoal sticks, he’d caused a U-shaped thread of electricity to “arc” across the gap between the sticks. The explosion of light was blindingly bright; perfect for light- ing dark outdoor areas, if it could be tamed into safety and reliability.

It is a concept that is not commonly covered in university courses but has a significant impact on the success of a site. This project examines the concepts of landscape lighting and suggests ideas to improve design standards while maintaining energy efficiency. This project will discuss methods and ideas of landscape lighting to improve energy efficiency. Designers should know lighting techniques and their energy efficient alternatives. This project demonstrates how design does not have to be compromised for the sake of energy efficiency.

  • The Compact Fluorescent Lamps Compared to General Service
    The Compact Fluorescent Lamps Author: Vitiuk Alexandr Ling. cons.: M. Ababii This article presents information on the compact fluorescent lamp (CFL), also known as an energy saving light, or less commonly as a compact fluorescent tube (CFT). Compared to general service incandescent lamps giving the same amount of visible light, CFLs generally use less power; have a longer rated life, but a higher purchase price. In the United States, a CFL can save over US $30 in electricity costs over the lamp's life time compared to an incandescent lamp and saves 2,000 times its own weight in greenhouse gases [1]. Like all fluorescent lamps, CFLs contain mercury, which complicates their disposal. The parent to the modern fluorescent lamp was invented in the late 1890s by Peter Cooper Hewitt [2]. This type of lamps were used for photographic studios and industries [3]. Construction. The most important technical advance has been the replacement of electromagnetic ballasts with electronic ones; this has removed most of the flickering and slow starting traditionally associated with fluorescent lighting. There are two types of CFLs: integrated and non-integrated lamps. Parts. There are two main parts in a CFL: the gas-filled tube (also called bulb or burner) and the magnetic or electronic ballast. The electrical current from the ballast flows through the gas, causing it to emit ultraviolet light. The ultraviolet light then excites a phosphor coating on the inside part of the tube. This coating emits visible light. CFL power sources. CFLs are produced for both alternating current (AC) and direct current (DC) input.
