Charles Pollak (born Karol Pollak), the inventor of the first electrolytic capacitors, found out that the oxide layer on an aluminum anode remained stable in a neutral or alkaline electrolyte, even when the power was switched off. In 1896 he filed a patent for an "Electric liquid capacitor with aluminum electrodes." Solid electrolyte tantalum capacitors were invented by Bell Laboratories in the early 1950s as a miniaturized and more reliable low-voltage support capacitor to complement their newly invented transistor.

In 1902, the first modern electrical air conditioning unit was invented by Willis Carrier in Buffalo, New York. After graduating from Cornell University, Carrier found a job at the Buffalo Forge Company. While there, he began experimenting with air conditioning as a way to solve an application problem for the Sackett - Wilhelms Lithographing and Publishing Company in Brooklyn, New York. The first air conditioner, designed and built in Buffalo by Carrier, began working on 17 July 1902.

In March 1875, Bell and Pollok visited the famous scientist Joseph Henry, who was then director of the Smithsonian Institution, and asked Henry's advice on the electrical multi-reed apparatus that Bell hoped would transmit the human voice by telegraph. Henry replied that Bell had "the germ of a great invention". When Bell said that he did not have the necessary knowledge, Henry replied, "Get it!" That declaration greatly encouraged Bell to keep trying, even though he did not have the equipment needed to continue his experiments, nor the ability to create a working model of his ideas. However, a chance meeting in 1874 between Bell and Thomas A. Watson, an experienced electrical designer and mechanic at the electrical machine shop of Charles Williams, changed all that.

In the United Kingdom, William Howard Livens invented a small, non-electric dishwasher suitable for domestic use in 1924. It was the first dishwasher that incorporated most of the design elements that are featured in the models of today; it included a front door for loading, a wire rack to hold the dirty crockery and a rotating sprayer. Drying elements were even added to his design in 1940. It was the first machine suitable for domestic use, and it came at a time when permanent plumbing and running water in the house was becoming increasingly common.

The Atwood machine (or Atwood's machine) was invented in 1784 by the English mathematician George Atwood as a laboratory experiment to verify the mechanical laws of motion with constant acceleration. Atwood's machine is a common classroom demonstration used to illustrate principles of classical mechanics.

In 1886, Frank Julian Sprague invented the first practical DC motor, a non-sparking motor that maintained relatively constant speed under variable loads. Other Sprague electric inventions about this time greatly improved grid electric distribution (prior work done while employed by Thomas Edison), allowed power from electric motors to be returned to the electric grid, provided for electric distribution to trolleys via overhead wires and the trolley pole, and provided controls systems for electric operations. This allowed Sprague to use electric motors to invent the first electric trolley system in 1887–88 in Richmond VA, the electric elevator and control system in 1892, and the electric subway with independently powered centrally controlled cars, which were first installed in 1892 in Chicago by the South Side Elevated Railway where it became popularly known as the "L". Sprague's motor and related inventions led to an explosion of interest and use in electric motors for industry, while almost simultaneously another great inventor was developing its primary competitor, which would become much more widespread. The development of electric motors of acceptable efficiency was delayed for several decades by failure to recognize the extreme importance of a relatively small air gap between rotor and stator. Efficient designs have a comparatively small air gap. [a] The St. Louis motor, long used in classrooms to illustrate motor principles, is extremely inefficient for the same reason, as well as appearing nothing like a modern motor.

Wilhelm Emil Fein (born 16 January 1842 in Ludwigsburg; died 6 October 1898 in Stuttgart) was a German inventor. He invented the worldwide first portable electric drill.

A sewing machine is a machine used to stitch fabric and other materials together with thread. Sewing machines were invented during the first Industrial Revolution to decrease the amount of manual sewing work performed in clothing companies. Since the invention of the first working sewing machine, generally considered to have been the work of Englishman Thomas Saint in 1790, the sewing machine has greatly improved the efficiency and productivity of the clothing industry.

The first commutator DC electric motor capable of turning machinery was invented by the British scientist William Sturgeon in 1832. Following Sturgeon's work, a commutator-type direct-current electric motor made with the intention of commercial use was built by the American inventor Thomas Davenport, which he patented in 1837. The motors ran at up to 600 revolutions per minute, and powered machine tools and a printing press. Due to the high cost of primary battery power, the motors were commercially unsuccessful and Davenport went bankrupt. Several inventors followed Sturgeon in the development of DC motors but all encountered the same battery power cost issues. No electricity distribution had been developed at the time. Like Sturgeon's motor, there was no practical commercial market for these motors.

Between 1882 and 1886 Schuyler Wheeler invented a fan powered by electricity. It was commercially marketed by the American firm Crocker & Curtis electric motor company. In 1882, Philip Diehl developed the world's first electric ceiling fan. During this intense period of innovation, fans powered by alcohol, oil, or kerosene were common around the turn of the 20th century. In 1909, KDK of Japan pioneered the invention of mass - produced electric fans for home use. In the 1920s, industrial advances allowed steel fans to be mass - produced in different shapes, bringing fan prices down and allowing more homeowners to afford them. In the 1930s, the first art deco fan (the ``swan fan '') was designed. By the 1940s, Crompton Greaves of India became the world's largest manufacturer of electric ceiling fans mainly for sale in India, Asia and the Middle East. By the 1950s, table and stand fans were manufactured in colors that were bright and eye catching.

Electric washing machines were advertised and discussed in newspapers as early as 1904. Alva J. Fisher has been incorrectly credited with the invention of the electric washer. The US Patent Office shows at least one patent issued before Fisher's US patent number 966677 (e.g. Woodrow's US patent number 921195). The ``inventor ''of the electric washing machine remains unknown.

Richmond emerged a decade after the smoldering rubble of the Civil War to resume its position as an economic powerhouse, with iron front buildings and massive brick factories. Canal traffic peaked in the 1860s and slowly gave way to railroads, allowing Richmond to become a major railroad crossroads, eventually including the site of the world's first triple railroad crossing. Tobacco warehousing and processing continued to play a role, boosted by the world's first cigarette-rolling machine, invented by James Albert Bonsack of Roanoke in 1880/81. Contributing to Richmond's resurgence was the first successful electrically powered trolley system in the United States, the Richmond Union Passenger Railway. Designed by electric power pioneer Frank J. Sprague, the trolley system opened its first line in 1888, and electric streetcar lines rapidly spread to other cities across the country. Sprague's system used an overhead wire and trolley pole to collect current, with electric motors on the car's trucks. In Richmond, the transition from streetcars to buses began in May 1947 and was completed on November 25, 1949.

The Trump tariffs are a series of tariffs imposed during the presidency of Donald Trump. In January 2018, Trump imposed tariffs on solar panels and washing machines, and later the same year, he imposed tariffs on steel and aluminum. On June 1, 2018, the United States imposed a 25% tariff on imports of steel, and a 10% tariff on aluminum, on the European Union, Canada, and Mexico.

The first successful machine - gun designs were developed in the mid-19th century. The key characteristic of modern machine guns, their relatively high rate of fire and more importantly mechanical loading, first appeared in the Model 1862 Gatling gun, which was adopted by the United States Navy. These weapons were still powered by hand; however, this changed with Hiram Maxim's idea of harnessing recoil energy to power reloading in his Maxim machine gun. Dr. Gatling also experimented with electric - motor - powered models; this externally powered machine reloading has seen use in modern weapons as well.

Following diplomatic negotiations dating back to 1990 among the three nations, U.S. President George H.W. Bush, Canadian Prime Minister Brian Mulroney and Mexican President Carlos Salinas signed the agreement in their respective capitals on December 17, 1992. The signed agreement was then ratified by each nation's legislative or parliamentary branch.

Bendix Home Appliances, a subsidiary of Avco, an otherwise unrelated company, who licensed the name from Bendix Corporation, introduced the first domestic automatic washing machine in 1937, having applied for a patent in the same year. In appearance and mechanical detail, this first machine was not unlike the front loading automatic washers produced today. Although it included many of the today's basic features, the machine lacked any drum suspension and therefore had to be anchored to the floor to prevent ``walking ''. Because of the components required, the machine was also very expensive. For instance, the Bendix Home Laundry Service Manual (published November 1, 1946) shows that the drum speed change was facilitated by a 2 - speed gearbox built to a heavy duty standard (not unlike a car automatic gearbox, albeit at a smaller size). The timer was also probably fairly costly, because miniature electric motors were expensive to produce.

Singer consolidated enough patents in the field to enable him to engage in mass production, and by 1860, his company was the largest manufacturer of sewing machines in the world. In 1885, Singer produced its first ``vibrating shuttle ''sewing machine, an improvement over contemporary transverse shuttle designs; (see bobbin drivers). Singer began to market its machines internationally in 1855 and won first prize at the Paris World's Fair. The company demonstrated the first workable electric sewing machine at the Philadelphia electric exhibition in 1889 and began mass - producing domestic electric machines in 1910. Singer was also a marketing innovator and was a pioneer in promoting the use of installment payment plans.

John Hopkinson, FRS, (27 July 1849 – 27 August 1898) was a British physicist, electrical engineer, Fellow of the Royal Society and President of the IEE (now the IET) twice in 1890 and 1896. He invented the three-wire (three-phase) system for the distribution of electrical power, for which he was granted a patent in 1882. He also worked in many areas of electromagnetism and electrostatics, and in 1890 was appointed professor of electrical engineering at King's College London, where he was also director of the Siemens Laboratory.
