Buffalo, New York
Buffalo is the second-largest city in the U.S. state of New York (behind only New York City) and the seat of Erie County. It is at the eastern end of Lake Erie, at the head of the Niagara River, and is across the Canadian border from Southern Ontario. With a population of 278,349 according to the 2020 census, Buffalo is the 78th-largest city in the United States. The city and nearby Niagara Falls together make up the two-county Buffalo–Niagara Falls Metropolitan Statistical Area (MSA), which had an estimated population of 1.1 million in 2020, making it the 49th largest MSA in the United States. Buffalo is in Western New York, which is the largest population and economic center between Boston and Cleveland. Before the 17th century, the region was inhabited by nomadic Paleo-Indians who were succeeded by the Neutral, Erie, and Iroquois nations. In the early 17th century, the French began to explore the region. In the 18th century, Iroquois land surrounding Buffalo Creek ...

Patented
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

North Tonawanda, New York
North Tonawanda is a city in Niagara County, New York, United States. The population was 31,568 at the 2010 census. It is part of the Buffalo–Niagara Falls Metropolitan Statistical Area. The city is named after Tonawanda Creek, its south border. Tonawanda in the Seneca tongue means "Swift Running Water". Tonawanda Creek, which flows into the Niagara River, once had large stretches of rapids (see Rapids, New York) until it was tamed with the construction of the Erie Canal. The city also calls itself "The Lumber City," due to its past primary industry and once was the largest port on the Great Lakes during the height of the Erie Canal. Along Goundry Street are mansions built for the lumber barons, including 208 Goundry Street, called "Kent Place", designed by Stanford White. Many of the local residents refer to it as "The Jewel of Niagara County" due to its geographical setting between the Niagara River and Erie Canal. It is also home to the 2009 Class AA NYS Football Champio ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

North Tonawanda Barrel Organ Factory
The North Tonawanda Barrel Organ Factory was a street organ manufacturing company and building, located in North Tonawanda, New York. Started by expatriate German Eugene de Kleist with backing from Allan Herschell, the company was later purchased by the Wurlitzer company. Foundations In 1892, the United States government imposed high import tariffs on both street and fairground organ importation. At this time only the French company of Gavioli had an office established in North America, but the move deterred other European organ manufacturers from doing the same. The result was that embryonic American fairground ride manufacturers were now starved of the highly quality instruments to attract fair goers, resulting in lower sales. In 1883, William Herschell, son of carousel builder Allan Herschell, traveled to London, England to meet former Limonaire Frères employee Eugene de Kleist. Backed by Herschell, in 1893 de Kleist set up band organ production in what was then part of Mar ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Wurlitzer
The Rudolph Wurlitzer Company, usually referred to as simply Wurlitzer, is an American company started in Cincinnati in 1853 by German immigrant (Franz) Rudolph Wurlitzer. The company initially imported stringed, woodwind and brass instruments from Germany for resale in the United States. Wurlitzer enjoyed initial success, largely due to defense contracts to provide musical instruments to the U.S. military. In 1880, the company began manufacturing pianos and eventually relocated to North Tonawanda, New York. It quickly expanded to make band organs, orchestrions, player pianos and pipe or theatre organs popular in theatres during the days of silent movies. Wurlitzer is most known for their production of entry level pianos. During the 1960s, they manufactured Spinet, Console, Studio and Grand Pianos. Over time, Wurlitzer acquired a number of other companies which made a variety of loosely related products, including kitchen appliances, carnival rides, player piano rolls and radi ...

Electrical Impedance
In electrical engineering, impedance is the opposition to alternating current presented by the combined effect of resistance and reactance in a circuit. Quantitatively, the impedance of a two-terminal circuit element is the ratio of the complex representation of the sinusoidal voltage between its terminals, to the complex representation of the current flowing through it. In general, it depends upon the frequency of the sinusoidal voltage. Impedance extends the concept of resistance to alternating current (AC) circuits, and possesses both magnitude and phase, unlike resistance, which has only magnitude. Impedance can be represented as a complex number, with the same units as resistance, for which the SI unit is the ohm (). Its symbol is usually , and it may be represented by writing its magnitude and phase in the polar form . However, Cartesian complex number representation is often more powerful for circuit analysis purposes. The notion of impedance is useful for perf ...

Voltage
Voltage, also known as electric pressure, electric tension, or (electric) potential difference, is the difference in electric potential between two points. In a static electric field, it corresponds to the work needed per unit of charge to move a test charge between the two points. In the International System of Units, the derived unit for voltage is named ''volt''. The voltage between points can be caused by the build-up of electric charge (e.g., a capacitor), and from an electromotive force (e.g., electromagnetic induction in generator, inductors, and transformers). On a macroscopic scale, a potential difference can be caused by electrochemical processes (e.g., cells and batteries), the pressure-induced piezoelectric effect, and the thermoelectric effect. A voltmeter can be used to measure the voltage between two points in a system. Often a common reference potential such as the ground of the system is used as one of the points. A voltage can represent either a source ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Electrochemical
Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential difference, as a measurable and quantitative phenomenon, and identifiable chemical change, with the potential difference as an outcome of a particular chemical change, or vice versa. These reactions involve electrons moving via an electronically-conducting phase (typically an external electrical circuit, but not necessarily, as in electroless plating) between electrodes separated by an ionically conducting and electronically insulating electrolyte (or ionic species in a solution). When a chemical reaction is driven by an electrical potential difference, as in electrolysis, or if a potential difference results from a chemical reaction as in an electric battery or fuel cell, it is called an ''electrochemical'' reaction. Unlike in other chemical reactions, in electrochemical reactions electrons are not transferred directly between atoms, ions, or molecules, but via the af ...

Catalyst Research Corporation
Catalysis () is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (). Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and temperature are important factors in reaction rate. Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process of regenerating the catalyst. Catalysis may be classified as either homogeneous, whose components are dispersed in the same phase (usually gaseous or liquid) as the reactant, or heterogeneous, whose components are not in the same phase. Enzymes and other biocatalysts are often considered as a third category. Catalysis is ubiquitous in chemical industry of all kinds. Estimates are that 90% of all commercially produced chemical products involve catalysts at some stag ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
