Flymo Flymo Flymo is a hover mower invented by Karl Dahlman. Dahlman invented the mower in 1964 after seeing Sir Christopher Cockerell's Hovercraft machine. "Flymo" is a brand name of the Swedish company Husqvarna AB, formerly a part of Electrolux. The mower is a variation of conventional petrol powered rotary push lawn mowers that uses a fan above the mower's spinning blades to allow the mower to "hover". Flymo mowers are powered rotary push lawn mowers that use a fan above the spinning blades to drive air downwards, thereby creating an air cushion that lifts the mower off the ground like
Karl Fischer titration Karl Fischer titration Karl Fischer titration is a classic titration method in analytical chemistry that uses coulometric or volumetric titration to determine trace amounts of water in a sample. It was invented in 1935 by the German chemist Karl Fischer. Today, the titration is done with an automated Karl Fischer titrator. The main compartment of the titration cell contains the anode solution plus the analyte. The anode solution consists of an alcohol (ROH), a base (B), SO and I. A typical alcohol that may be used is ethanol or diethylene glycol monoethyl ether, and a common base is imidazole. The
