Prior Art
Prior art (also known as state of the art or background art) is a concept in patent law used to determine the patentability of an invention, in particular whether an invention meets the novelty and the inventive step or non-obviousness criteria for patentability. In most systems of patent law, prior art is generally defined as anything that is made available, or disclosed, to the public that might be relevant to a patent's claim before the effective filing date of a patent application for an invention. However, notable differences exist in how prior art is specifically defined under different national, regional, and international patent systems. The prior art is evaluated by patent offices as part of the patent granting process in what is called “substantive examination” of a patent application in order to determine whether an invention claimed in the patent application meets the novelty and inventive step or non-obviousness criteria for patentability. It may also be consid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1952 Deaths
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Hjalmar Öhrvall
Hjalmar () and Ingeborg () were a legendary Swedish duo. The male protagonist Hjalmar and his duel for Ingeborg figures in the '' Hervarar saga'' and in '' Orvar-Odd's saga'', as well as in ''Gesta Danorum'', ''Lay of Hyndla'' and a number of Faroese ballads. Hjalmar never lost a battle until meeting a berserker wielding the cursed sword Tyrfing. A tale of two heroes Hjalmar was one of the mythical Swedish king Yngvi's housecarls at Uppsala. He and princess Ingeborg were in love, but the king said no to his requests for marriage, since he hoped for a suitor with a better pedigree. Hjalmar's reputation as a courageous and valiant warrior was great and it reached the most remote parts of Norway, where the Norwegian hero Orvar-Odd felt a desire to test his fighting skills with Hjalmar. Thus Orvar-Odd sailed to Sweden with five ships and met Hjalmar who had fifteen ships. Hjalmar could not accept such an uneven balance of strength and sent away ten of his own ships so that the force ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philip Drinker
Philip Drinker (December 12, 1894 – October 19, 1972) was an industrial hygienist. With Louis Agassiz Shaw, he invented the first widely used iron lung in 1928. Family and early life Drinker's father was railroad man and Lehigh University president Henry Sturgis Drinker; his siblings included lawyer and musicologist Henry Sandwith Drinker, Jr., pathologist Cecil Kent Drinker, businessman James Drinker, and biographer Catherine Drinker Bowen. After graduating from St. George's and Princeton in 1915, Philip Drinker trained as a chemical engineer at Lehigh for two years. Drinker was hired to teach industrial illumination and ventilation at Harvard Medical School and soon joined his brother Cecil and colleagues Alice Hamilton and David L. Edsall on the faculty of the nascent Harvard School of Public Health in 1921 or 1923.

John Haven Emerson
John Haven Emerson (February 5, 1906 – February 4, 1997) was an American inventor of biomedical devices, specializing in respiratory equipment. He is perhaps best remembered for his work in improving the iron lung. Early life Emerson was born in 1906 in New York City, the son of Dr. Haven Emerson, Health Commissioner of New York City, and Grace Parrish Emerson, the sister of Maxfield Parrish. He was named for his paternal grandfather (1840–1913), who was also a medical doctor. At the age of 22, he bought a rudimentary machine shop from the estate of a local inventor. He moved the equipment to a small warehouse in Harvard Square, in Cambridge, Massachusetts, where he built research apparatus for professors and researchers of Boston-area medical schools, and produced many inventions over the following years. In 1928, he designed a Barcroft-Warburg apparatus for tissue respiration studies. In 1930, he designed a new type of micromanipulator which was valuable in early physiology ...

Hans Krebs (biochemist)
Sir Hans Adolf Krebs, FRS (, ; 25 August 1900 – 22 November 1981) was a German-born British biologist, physician and biochemist. He was a pioneer scientist in the study of cellular respiration, a biochemical process in living cells that extracts energy from food and oxygen and makes it available to drive the processes of life. He is best known for his discoveries of two important sequences of chemical reactions that take place in the cells of humans and many other organisms, namely the citric acid cycle and the urea cycle. The former, often eponymously known as the "Krebs cycle", is the key sequence of metabolic reactions that provides energy in the cells of humans and other oxygen-respiring organisms; and its discovery earned Krebs a Nobel Prize in Physiology or Medicine in 1953. With Hans Kornberg, he also discovered the glyoxylate cycle, which is a slight variation of the citric acid cycle found in plants, bacteria, protists, and fungi. Krebs died in 1981 in Oxford, wh ...

Magnus Blix
Magnus Gustaf Blix (25 December 1849 – 14 February 1904) was a Swedish physiologist born in the parish Säbrå, presently located in Härnösand Municipality. He is the grandfather of UN weapons inspector Hans Blix. During his career he was a professor at the Universities of Uppsala and Lund. Blix was elected a member of the Royal Swedish Academy of Sciences in 1892. Blix is best known for his work in the 1880s involving somatic sensation. He discovered that electrical stimulation on different points on the surface of the skin caused distinct warm or cool sensations. Subsequently he built a "temperature stimulator" which showed that a decreased skin temperature produced cool sensations from localized spots at separate skin locations. He also discovered that increased temperature induced warm sensations from different cutaneous locations. In addition he performed tests that involved localized tactile sensitivity. In 1881–82 Blix published his findings in two important docu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
