United States Federal republic in North America

The United States of America (USA), commonly known as the United States or America, is a country comprising 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is slightly smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U.S. is the third most populous country. The capital is Washington, D.C., and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico. The State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean. The U.S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The extremely diverse geography, climate, and wildlife of the United States make it one of the world's 17 megadiverse countries.

Mexico Country in the southern portion of North America

Mexico, officially the United Mexican States, is a country in the southern portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost 2,000,000 square kilometres (770,000 sq mi), the nation is the fifth largest country in the Americas by total area and the 13th largest independent state in the world. With an estimated population of over 120 million people, the country is the eleventh most populous state and the most populous Spanish-speaking state in the world, while being the second most populous nation in Latin America after Brazil. Mexico is a federation comprising 31 states and Mexico City, a special federal entity that is also the capital city and its most populous city. Other metropolises in the state include Guadalajara, Monterrey, Puebla, Toluca, Tijuana and León.

Europe Continent in the Northern Hemisphere and mostly in the Eastern Hemisphere

Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west and the Mediterranean Sea to the south. It comprises the westernmost part of Eurasia.



In 1922, Louis Desloge Sr. of the Desloge family founded Watlow in a rented corner space on the second floor of a machine shop in St. Louis, Missouri, and began manufacturing electric heating elements for the shoe industry. The name Watlow refers to the “low-watt” heaters that replaced stream heat. [2]

The Desloge family is a French American family centered mostly in Missouri and especially at St. Louis, that rose to wealth through international commerce, sugar refining, oil drilling, fur trading, mineral mining, saw milling, manufacturing, railroads, real estate, and riverboats. The family has funded hospitals and donated large tracts of land for public parks and conservation.

St. Louis Independent city in the United States

St. Louis is an independent city and inland port in the U.S. state of Missouri. It is situated along the western bank of the Mississippi River, which marks Missouri's border with Illinois. The Missouri River merges with the Mississippi River just north of the city. These two rivers combined form the fourth longest river system in the world. The city had an estimated 2017 population of 308,626 and is the cultural and economic center of the St. Louis metropolitan area, which is the largest metropolitan area in Missouri, the second-largest in Illinois, and the 22nd-largest in the United States.

Missouri State of the United States of America

Missouri is a state in the Midwestern United States. With over six million residents, it is the 18th-most populous state of the Union. The largest urban areas are St. Louis, Kansas City, Springfield, and Columbia; the capital is Jefferson City. The state is the 21st-most extensive in area. In the South are the Ozarks, a forested highland, providing timber, minerals, and recreation. The Missouri River, after which the state is named, flows through the center of the state into the Mississippi River, which makes up Missouri's eastern border.

During the 1930s and 1940s, Watlow began selling products outside the United States. Louis' sons Louis Jr. and George joined the company. A few years later, George invented the FIREROD cartridge heater. The first swaged cartridge heater, the patented device greatly increased heat transfer efficiency. [3] Together, the Desloges expanded Watlow’s headquarters and St. Louis manufacturing facility to 185,000 square feet. During the mid-1970s, the company introduced the industry's first thermocouple product. Shortly after this time, Watlow grew exponentially both globally and domestically, adding facilities in Kronau, Germany, and Columbia, Missouri; and acquiring the Claud S. Gordon Company of Richmond, Illinois, the nation’s leading manufacturer of temperature measurement devices. [4] In 1997, Watlow celebrated its 75th anniversary in the thermal products industry.

Swaging is a forging process in which the dimensions of an item are altered using dies into which the item is forced. Swaging is usually a cold working process, but also may be hot worked.

Thermocouple thermoelectric device

A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming electrical junctions at differing temperatures. A thermocouple produces a temperature-dependent voltage as a result of the thermoelectric effect, and this voltage can be interpreted to measure temperature. Thermocouples are a widely used type of temperature sensor.

Germany Federal parliamentary republic in central-western Europe

Germany, officially the Federal Republic of Germany, is a country in Central and Western Europe, lying between the Baltic and North Seas to the north, and the Alps, Lake Constance and the High Rhine to the south. It borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, France to the southwest, and Luxembourg, Belgium and the Netherlands to the west.

In 2000, Watlow Batavia Inc., then a subsidiary of Watlow, settled a lawsuit brought by the U.S. Equal Employment Opportunity Commission over the company's English-only policy. [5] The company had fired eight Spanish-speaking workers. The EEOC alleged that the firings amounted to unlawful discrimination based on national origin, and that Watlow Batavia Inc.'s workplace lacked the safety-related conditions that make an English-only policy permissible. Watlow Batavia Inc. paid $192,500, the largest settlement in the four years since the EEOC had started keeping track. Officials denied any company wrongdoing and said they were settling the suit only to avoid litigation. [6] [7] In 2010, the company sold Watlow Batavia to LV2 Equity Partners of Midland, Michigan. [8]

Equal Employment Opportunity Commission

The U.S. Equal Employment Opportunity Commission (EEOC) is a federal agency that administers and enforces civil rights laws against workplace discrimination. The EEOC investigates discrimination complaints based on an individual's race, children, national origin, religion, sex, age, disability, sexual orientation, gender identity, genetic information, and retaliation for reporting, participating in, and/or opposing a discriminatory practice.

[9] In 2015, Watlow launched their new F4T with INTUITION, a touch-screen controller that combines the functions of several devices into one process control. [10]

Microvision handheld game console

The Microvision is the first handheld game console that used interchangeable cartridges. It was released by the Milton Bradley Company in November 1979. The Microvision was designed by Jay Smith, the engineer who would later design the Vectrex gaming console. The Microvision's combination of portability and a cartridge-based system led to moderate success, with Smith Engineering grossing $15 million in the first year of the system's release. However, very few cartridges, a small screen, and a lack of support from established home video game companies led to its demise in 1981. According to Satoru Okada, the former head of Nintendo's R&D1 Department, the Microvision gave birth to the Game & Watch after Nintendo designed around Microvision's limitations.
