Gyrotheodolite This principle was adapted by Max Schuler in 1921 to build the first surveying gyro. In 1949, the gyro-theodolite-at that time called a meridian pointer or meridian indicator - was first used by the Clausthal Mining Academy underground. Several years later it was improved with the addition of autocollimation telescopes.

Bruno Abakanowicz Earlier he invented the integraph, a form of the integrator, which was patented in 1880, and was henceforth produced by the Swiss firm Coradi. Among his other patents were the parabolagraph, the spirograph, the electric bell used in trains, and an electric arc lamp of his own design. Abakanowicz published several works, including works on statistics, integrators and numerous popular scientific works, such as one describing his integraph.

- The history of the ballpoint pen Article added on October 17+18, 2002 The history of the ball-point pen In 1879 in Providence, Rhode Island, Alonzo T. Cross invented the stylographic fountain pen, a precursor of the ball-point pen. He engaged in competition with Duncan Mackinnon, the other stylographic pen inventor.he first to think of it was the German inventor Baum who patented a ball-point pen (Kugelschreiber) in 1910. However, the first man to actually develop and launch a ball-point pen was the Hungarian L szl Jozsef B r (1899-1985) from Budapest, who in 1938 invented a ball-point pen with a pressurized ink cartridge.

The History of EM This was, in retrospect, the moment of the invention of the electron microscope but the first prototype was actually built by Ruska in 1933 and was capable of resolving to 50 nm. Although it was primitive and not really fit for practical use, Ruska was recognised some 50 years later by the award of a Nobel Prize.

Tracking Innovation: Windshield Wipers Anderson was granted U.S. patent number 743,801 for her novel windshield wiper in November of 1903. By 1916, windshield wipers were standard equipment on all American cars. Although upgrades continue to be made to the windshield wiper, the basic principle and function that Anderson invented remains unchanged. Some notable enhancements include automatic wipers, which were patented in 1917 by Charlotte Bridgwood; intermittent wipers, which were patented by Robert W. Kearns in 1967; and heated windshield wiper blades.

Sensors power next-generation Structural Health Monitoring in civil engineering applications Such devices include: 1  Inclinometers – measure horizontal and vertical angular inclination to very high levels of precision, and output the data in analogue or digital form. In SHM applications, inclinometers are employed to monitor movement over time of bridges, buildings and other large structures.
