Discoveries and Inventions
1904 - Patent for the first direct current, interpole, electric motor in the U.S. was issued to Mathias Pfatischer of Phildadelphia, Pennsylvania under the title "Variable Speed Motor" (No.775,310).
The improvement claimed in the patent was to "effect commutation without sparking, with a variable load as well as at variable speed and which is capable of rotation in either direction." The new design added auxiliary-field pole-pieces which were small as compared to the main pole-pieces.
1932 - , the first U.S. patent for a pump with computing facility was issued to the inventors, Robert J. Jauch, Ivan R. Farnham and Ross H. Arnold for their "Liquid Dispensing Apparatus" (No. 1,888,533). The pump with the computing facility metered and displayed the exact gallons of gasoline or other liquid dispensed, and also accurately computed and showed the price in dollars and cents of the quantity delivered.
1941, in the Federal Register, the U.S. Food and Drug Administration specified the first minimum daily requirements for dietary supplements - for vitamin A, vitamin C, vitamin D, thiamine, riboflavin, calcium, iron, iodine, and phosphorus.
1977 - First three nodes of the ARPAnet are connected, in what would eventually become the Internet.
1809 - Benedict Augustin Morel - Austrian-born French psychologist. He used the term dementia praecox to refer to a mental and emotional deterioration beginning at the time of puberty. The disorder was renamed schizophrenia in 1908 by the Swiss psychologist Eugen Bleuler. He authored 700-page book "Traité des dégenerescences physiques, intellectuelles et morales de l'espèce humaine" in 1857. In it he described many physical signs - various malformations - and various intellectual and moral deviations from the normal that are to be charatcertized as mental sickness.
1904 - Louis-Eugène-Félix Néel - French physicist who shared, (with the Swedish astrophysicist Hannes Alfvén) the Nobel Prize for Physics in 1970 for his pioneering studies of the magnetic properties of solids. His contributions to solid-state physics were used in the development of improved computer memory units.
1917 - Andrew Fielding Huxley - English physiologist - (with Sir Alan Hodgkin and Sir John Carew Eccles) the 1963 Nobel Prize for Physiology or Medicine - the chemical phenomena - the “sodium pump” mechanism - by which nerve impulses are transmitted.
