ClearSign Technologies. ClearSign Technologies Corporation (ClearSign) is a United States-based company that develops emission-control technology.

Products

ClearSign develops technology intended to increase energy efficiency and emissions standards of combustion systems, primarily industrial and commercial boilers and furnaces. Its products include Duplex Burner Architecture, which the company says reduces combustion burner flame length by more than 80-percent, in turn increasing thermal capacity and reducing operating costs. Duplex Burner Architecture won the "New Technology Development of the Year Award" at the 2014 West Coast Oil & Gas Awards. The company's other major product is Electrodynamic Combustion Control, which uses computer-controlled electric fields to control the flame shape in boilers, kilns, and furnaces,  preventing pollution from forming.

History

ClearSign was formed in Seattle, Washington in 2008. Its first chief executive officer was Richard Rutkowski, who also became chairman of the board of directors. Rutkowski was a co-founder of projection technology company Microvision and nanotechnology company Lumera.

In 2012 ClearSign held an initial public offering which, according to the company, raised $13.8 million. ClearSign chose to delay adopting accounting standards required of publicly traded companies under the Sarbanes-Oxley Act, taking advantage of exemptions in the JOBS Act designed to make it cheaper for development-stage companies to raise capital. It is believed ClearSign may have been the first company in the U.S. to do so.

In December 2014, Rutkowski resigned as CEO. He was replaced by board member Stephen Pirnat. The following September, the company was named "Technology Company of the Year" by Petroleum Economist.

On November 12, 2019, ClearSign Combustion Corporation (Nasdaq: CLIR) (“ClearSign” or the “Company”), announced that the Company has changed its name to ClearSign Technologies Corporation. The Company’s ticker “CLIR” will remain the same.

Lead-glazed earthenware. Lead-glazed earthenware is one of the traditional types of earthenware with a ceramic glaze, which coats the ceramic bisque body and renders it impervious to liquids, as terracotta itself is not. Plain lead glaze is shiny and transparent after firing. Coloured lead glazes are shiny and either translucent or opaque after firing. Three other traditional techniques are tin-glazed (in fact this is lead glaze with a small amount of tin added), which coats the ware with an opaque white glaze suited for overglaze brush-painted colored enamel designs; salt glaze pottery, also often stoneware; and the feldspathic glazes of Asian porcelain. Modern materials technology has invented new glazes that do not fall into these traditional categories.

In lead glazes, tints provided by impurities render greenish to brownish casts, with aesthetic possibilities that are not easily controlled in the kiln. The Romans used lead glazes for high-quality oil lamps and drinking cups. At the same time in China, green-glazed pottery dating back to the Han period (25–220 AD) gave rise eventually to the sancai ('three-color') Tang dynasty ceramics, where the white clay body was coated with coloured glazes and fired at a temperature of 800 degrees C. Lead oxide was the principal flux in the glaze. Polychrome effects (i.e. the colours) were obtained by using the oxides of copper (which turns green), iron (brownish yellow), and less often manganese (brown) and cobalt (blue). 

Much of Roman technology was lost in the West, but coarse lead-glazed earthenwares were universal in medieval Europe and in Colonial America. In England, lead-glazed Stamford ware was produced in Stamford, Lincolnshire as early as the ninth century. It was widely traded across Britain and the near continent. In Italy during the 15th century lead-glazed wares were improved by the incremental addition of tin oxides under the influence of Islamic wares imported through Sicily, giving rise to maiolica, which supplanted lead-glazed wares in all but the most rustic contexts. The French 16th-century Saint-Porchaire ware is lead-glazed earthenware; an early European attempt at rivalling Chinese porcelains, it does not properly qualify as faience, which is a refined tin-glazed earthenware. In 16th-century France Bernard Palissy refined lead-glazed earthenware to a high standard. Victorian majolica is predominantly lead-glazed 'majolica' earthenware, introduced by Mintons in the mid-19th century as a revival of "Palissy ware". Victorian majolica also include Minton's rare tin-glaze products.

Lead-glazed earthenwares in Britain include the Toby jugs, such as those made in the late 18th century by Ralph Wood the Younger at Burslem, Staffordshire.

Herbert Raab. Herbert Raab (born 24 January 1969 in Linz, Austria) is an Austrian software engineer, amateur astronomer and discoverer of astronomical objects.

Biography 
Raab finished his studies of computer science at the Johannes Kepler University of Linz in 1995 as a graduate engineer. In 2012, he received the Master of Science in Management for Engineers at the LIMAK business school in Linz, where he also graduated as Master of Business Administration in 2013. He works as a software engineer in the field of commercial software.

In 1983, he joined the Astronomical Society of Linz (), and has been president of the society from 1996 until 2017. Since 1990, he has been developing the widely used software Astrometrica, which is used for astrometric and photometric analysis of images of asteroids and comets. Raab's most important observations include precise astrometry of the comet Shoemaker–Levy 9, which he observed together with Erich Meyer and Erwin Obermair in 1993. These observations have significantly contributed to the subsequent prediction of the impact of this comet on the planet Jupiter.

On 10 August 1997, he discovered the asteroid 13682 Pressberger together with Erich Meyer at the private observatory Meyer/Obermair in Davidschlag (municipality Kirchschlag bei Linz, Austria). Furthermore, he was involved in three other discoveries of asteroids which were assigned as site discoveries to the observatory Davidschlag by the International Astronomical Union (see :Category:Discoveries by the Davidschlag Observatory). During the Occultation of the star HIP 76293 by the asteroid 1177 Gonnessia on 18 May 2007, Raab discovered that the star is a close double star, whose components have a separation of just 0.04".

In May 1996, asteroid 3184 Raab was named in his honor, following a proposal of Brian G. Marsden and Gareth V. Williams from the Minor Planet Center (). On 4 April 1997, Raab was presented the Gold Medal for Services to the Republic of Austria.

His wife Agnes Raab (born 1969) is also an amateur astronomer and long-time member of the Astronomical Society of Linz. In early 2004, asteroid 49109 Agnesraab, was .

Joseph H. Hoadley. Joseph H. Hoadley (July 1863 – ?) was an American financier charged with fraud on several occasions. He was president of International Power Co.

Biography
He was born in San Francisco, California in July 1863, to a family of New England descent with connections to mechanical engineering inventions He began his career in 15 as an apprentice in Union Brass & Iron Works machine shop, but before completing his apprenticeship he moved on to Pacific steam liner SS City of Tokio and worked his way over to one of her engineers.

After returning to complete his apprenticeship, Hoadley worked briefly as a locomotive engineer on the Southern Pacific. By age 21, he had become superintendent of the Calico mines in Southern California. He then established himself as a contractor for mining machinery, installing plants across several western states including California, Idaho, Washington, Montana, Oregon, and Alaska. Hoadley expanded his business to include contracts for power-house plants, street railroads, electric-lighting plants, and various industrial facilities, and by 1894 he had moved his headquarters to Chicago, linking his western operations with new ventures in the Midwest.

In 1902 he headed American Ordnance Company based in Bridgeport which manufactured Driggs-Schroeder and Hotchkiss naval guns and negotiated the acquisition of competing Driggs-Seabury. By 1906 he was a defendant before the New York Supreme Court in a trial with Elizabeth C. Prall.

In 1916 he was sentenced to Ludlow Street Jail, when the police came to detain him at his house, and suspect that he escaped through a secret tunnel.

In 1918 he lost a lawsuit and was ordered to pay $999,389 to the American & British Mfg. Co.

His wife died by suicide in 1919 by inhaling illuminating gas. The police investigated her death as a possible murder. He was then ordered out of his house for non payment of his mortgage. The house was sold, and he claimed to the court that he had an arrangement with the new owner where he was not required to pay rent.

In 1932 he was arrested and convicted of check fraud for $1,037, and sentenced to three months in a workhouse.

Issac Koga. was a Japanese inventor and scientist.

Early life and education 
He was the eldest of seven children born in Tashiro Village (now Tosu), Saga Prefecture. In July 1920, at the age of 20, he started to study at the Department of Electrical Engineering at Tokyo Imperial University (later renamed University of Tokyo). After graduation in August 1925, he moved to the new Tokyo City Electrical Institute, which was established to develop and promote radio broadcasting technology under the directorship of Kotaro Kujirai, a pioneer of the research and teaching of radio science.  

Initially an engineer, he became an assistant professor in 1929.  Under the guidance of Professor Kujirai, he studied crystal oscillators. This formed the basis of his PhD thesis, completed in April 1930, entitled "Characteristics of the Crystal Oscillator." This work included making the first quartz tuning forks in 1927. In 1929, he became an associate professor at the Tokyo Institute of Technology and a professor in 1939. In 1944, he worked as a concurrent professor at the University of Tokyo, later became a professor emeritus there, and reached emeritus status at Tokyo Institute of Technology in 1961.

Research works 
His research and education were in the areas of electronics and communications. Koga is an inventor of temperature insensitive quartz cut (R1-cut) of quartz plate quartz crystal: in April 1933, Issac Koga at Tokyo Institute of Technology reported R1-cut quartz crystal plates having a zero temperature-coefficient of frequency. He applied the R1-cut plate to wireless communications and quartz clocks; his achievement provided stable frequency of oscillator used in communications and clocks for time standard. This type of temperature-insensitive quartz crystal oscillator has been indispensable to all radio communication systems and much of information electronics.

Awards and recognitions 
He was awarded the Japan Academy Prize in 1948 (the citation reads for "Theoretical and Experimental Investigation upon the Fundamental Characteristics of Piezoelectric Oscillating Crystal and Quartz Crystal Oscillator Circuit and Their Applications to Wireless Communication and Crystal Clock"),
 the Order of Cultural Merit award in 1963 and  became a member of the Japanese Academy in 1971. He served as president of the International Union of Radio Science (URSI) between 1963 and 1968.

Koga died on September 2, 1982. In his honor, the International Union of Radio Science, URSI, named a young scientist award after him (the Issac Koga Gold Medal ) first awarded in 1984 and subsequently awarded every 3 years.

Lyman C. Craig. Lyman C. Craig (born 1906 in Palmyra Township, Warren County, Iowa; died 1974) was a chemical researcher who worked at The Rockefeller Institute for Medical Research from 1933 onward. In 1944 he published a seminal work on countercurrent distribution, which became an important separation technique. Craig continued to develop the theory, improve the apparatus and devise new applications of the countercurrent distribution into the 1970s. Countercurrent distribution not only proved to be a useful separation technique, it also inspired the development of the field of countercurrent chromatography. In 1950, Craig invented the rotary evaporator which is a necessary equipment in most chemical labs. He also invented the Craig tube, an apparatus used in small-scale chemistry, in particular for recrystallization. He received recognition from his peers and several honors for his scientific accomplishments. He was elected to the National Academy of Sciences in 1950. He was the recipient of the 1963 Albert Lasker Award for Basic Medical Research. He also was nominated for the Nobel Prize in Chemistry.
