Transformers, the Unsung Technology

It so puts to shame all mechanical attempts at regulation, it handles with such ease, certainty, and economy vast loads of energy that are instantly given to or taken from it. It is so reliable, strong, and certain. In this mingled steel and copper, extraordinary forces are so nicely balanced as to be almost unsuspected.” The biggest modern incarnations of this enduring design have made it pos- sible to deliver electricity across great distances. In 1890, de Ferranti stepped up from 2.5 kilovolts to 10 kV, enough to bridge 11 kilometers in London. Now ABB, based in Zurich, is working on stepping up to a record-breaking 1,100 kV, to span more than 3,000 km in China. The sheer number of transformers has risen above anything Stanley could have imagined, thanks to the explosion of por- table electronic devices that have to be charged.

International Journal for Research in Engineering Application & Management (IJREAM) ISSN : 2454-9150 Vol-03, Issue-11, Feb 2018 Pedaling Energy Harvesting by Low Speed Gearless Generator 1Prof T. T. Bellundagi, 2Prof A. S. Jaibhai, 3Prof A. E. Shivdas 1,2,3Assistant Professor, 1, 2, 3Electrical Dept TSSM’S BSCOER Narhe Pune, India. [email protected], [email protected], [email protected] Abstract - In rural areas of India today also we use bicycle as main medium of transportation. The pedaling energy generated is wasted. It can be used for a better purpose by converting pedaling power in to electrical energy. The same concept of the energy generated due to pedaling can be obtained by gym cycles in urban areas. The energy generated can be stored and can be used for running electrical appliances [1]. These types of systems are already available in markets but they are less efficient, needs more rpm to generate power. This paper presents design of gym cycle which produces same output with less rpm. In this paper low speed generator is designed and modified the position of generator which eliminates gears and belt arrangement. In Low speed generator high power magnets are implemented and number of poles are increased also gauge of winding used is 23.The main intention of this paper is to build straight forward human powered low speed generator. It is clean way of generating energy efficiently. Keywords – Pedaling Energy, Gearless Generator, harvesting, low speed generator, electrical appliances. I. INTRODUCTION II.

An Abstract of “Keep Your Dirty Lights On:” Electrification and the Ideological Origins of Energy Exceptionalism in American Society by Daniel A. French Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Doctor of Philosophy Degree in History The University of Toledo December 2014 Electricity has been defined by American society as a modern and clean form of energy since it came into practical use at the end of the nineteenth century, yet no comprehensive study exists which examines the roots of these definitions. This dissertation considers the social meanings of electricity as an energy technology that became adopted between the mid- nineteenth and early decades of the twentieth centuries. Arguing that both technical and cultural factors played a role, this study shows how electricity became an abstracted form of energy in the minds of Americans. As technological advancements allowed for an increasing physical distance between power generation and power consumption, the commodity of electricity became consciously detached from the steam and coal that produced it. -

Historic Amusement Parks and Fairground Rides Introductions to Heritage Assets Summary
Historic Amusement Parks and Fairground Rides Introductions to Heritage Assets Summary Historic England’s Introductions to Heritage Assets (IHAs) are accessible, authoritative, illustrated summaries of what we know about specific types of archaeological site, building, landscape or marine asset. Typically they deal with subjects which lack such a summary. This can either be where the literature is dauntingly voluminous, or alternatively where little has been written. Most often it is the latter, and many IHAs bring understanding of site or building types which are neglected or little understood. Many of these are what might be thought of as ‘new heritage’, that is they date from after the Second World War. With origins that can be traced to annual fairs and 18th-century pleasure grounds, and much influenced by America’s Coney Island amusement park of the 1890s, England has one of the finest amusement park and fairground ride heritages in the world. A surprising amount survives today. The most notable site is Blackpool Pleasure Beach, in Lancashire, which has an unrivalled heritage of pre-1939 fairground rides. Other early survivals in England include scenic railways at Margate and Great Yarmouth, and water splash rides in parks at Kettering, Kingston-upon-Hull and Scarborough that date from the 1920s.

The History of Sir Hiram Maxim
The History of Sir Hiram Maxim On a small hill overlooking Dexter's Lake Wasookeag on a June day in 1890, a gathering of townspeople watched history in the making as bullets whizzed into the lake waters at a rate of 666 per minute. The small-town quiet was shattered as the gun swayed back and forth to show how a fast-moving army could be cut down in minutes. From that location, about 10 miles from his Sangerville home, Sir Hiram Maxim's gun entered the battlefields of the Russo- Japanese War and later World War I, World War II, and even the battlefields of Korea and Vietnam. As a boy, Hiram Maxim lived at Brockway Mills, located off Silvers Mills Road. Born on the fifth of February, 1840 in a less than modest home - on a small knoll overlooking a stream, he tended sheep throughout the summer months. Legend has it, as a young lad he and his brother Hudson stood atop a large boulder outside their home and with raised arms pledged to themselves that someday they would become famous. Both men achieved fame and garnered themselves a place in the history books. Hiram's only schooling was what he gleaned from five years of learning in a one-room Sangerville schoolhouse. At the age of 14, he was apprenticed to Daniel Sweat, an East Corinth carriage maker who had recently returned to Sangerville. Hiram went to work for Mr. Sweat in Abbott and it was there that he perfected his first invention - an automatic mousetrap that soon rid the Abbot grist mill of mice. -

To the producers of the official statistics of educational organization in Victorian England the term clearly did not apply to the myriad small, local and often informal places of learning attended by many working-class children. Official statistics in consequence do not take account of the educational reality of the industrial and urban working class. In this very important contribution to the history of English education, Phil Gardner demonstrates that historians of education generally- even those on the left- have reproduced a part of the official view of working-class schooling. -
American and German Machine Guns Used in WWI
John Frederick Andrews Novels of the Great War American and German Machine Guns Used in WWI The machine gun changed the face of warfare in WWI. The devastating effects of well-emplaced machine guns against infantry and cavalry became brutally evident in the 1st World War. It changed infantry tactics forever. The US Marines and Army had several machine guns available during the war. This brief will discuss crew-served machine guns only. Man-portable automatic rifles are discussed in another article. The Lewis gun is mentioned here for completeness. The Marine 1st Machine Gun Battalion, commanded by Maj. Edward Cole trained with the Lewis gun before shipping overseas. The gun had been used by the British with good effect. Cole’s men trained with at the Lewis facility in New York. At that point, the plan was for each company to have an eight-gun machine gun platoon. A critical shortage in the aviation community stripped the Marines of their Lewis guns before they shipped to France. The Lewis Gun weighed 28 pounds and was chambered in the .303 British, .30.06 Springfield, and 7.92x57 mm Mauser. They were fed by a top-mounted magazine that could hold 47 or 96 rounds. Rate of fire was 500-600 rounds per minute with a muzzle velocity of 2,440 feet per second and an effective range of 880 yards and a maximum of 3,500 yards. The infantry model is shown below.

George Westinghouse and the Business of Innovation During the Age of Edison
Steven W. Usselman From Novelty to Utility: George Westinghouse and the Business of Innovation during the Age of Edison This article argues that Thomas Edison and George West- inghouse, despite some shared characteristics in their approach to technical problems and a common interest in electric power, pursued distinct markets for innovation. Edison sold novelties to upper-class urbanites, whereas Westinghouse provided equipment to railroads and other industrial customers. As a consequence, the two entrepre- neurs consistently exhibited different attitudes toward the process of innovation and different inclinations as business- men. Westinghouse, more than Edison, foreshadowed the coming of corporate research and development. ince the late 1970s, few areas of inquiry in business history Shave proved as fruitful as the study of corporate research and development. Moving beyond an older, simpler image of R&D as science applied by industry to produce novelty, historians now interpret R&D programs as components of corporate strategies designed to address specific business conditions.1 Corporations typically created laboratories in hopes of attaining order and con- trol over established lines of business.2 In joining programs of technological development to their production and marketing STEVEN W. USSELMAN is associate professor of history at the University of North Carolina at Charlotte.
