Trolleybus - Wikipedia

HistoryVehicle DesignAdvantagesDisadvantagesOff-Wire Power DevelopmentsOther ConsiderationsWire SwitchesManufacturingTransition to Low-Floor DesignsDouble-Decker TrolleybusesThe trolleybus dates back to 29 April 1882, when Dr. Ernst Werner Siemens demonstrated his "Elektromote" in a Berlin suburb. This experiment continued until 13 June 1882, after which there were few developments in Europe, although separate experiments were conducted in the U.S. In 1899, another vehicle which could run either on or off rails was demonstrated in Berlin. The next development was when Louis Lombard-Gérin operated an experimental line at the Paris Exhibition of 1900 after four years of trials, with a circular route around Lake Daumesnil that carried passengers. Routes followed in six places including Eberswalde and Fontainebleau. Max Schiemann on 10 July 1901 opened the worldfourth passenger-carrying trolleybus system, which operated at Bielatal (Biela Valley, near Dresden), in Germany. Schiemann built and operated the Bielatal system, and is credited with developing the under-running trolley current collection system, with two horizontally parallel overhead wires and...Get price

IDA71 - Wikipedia

Operating ModesGalleryExternal LinksThe IDA-71 can be used as an oxygen rebreather, or with the addition of an external cylinder, as a nitrox rebreather, which converts between nitrox and oxygen automatically by a pressure activated valve on the nitrox attachment. It can run as an ordinary diving rebreather. Or it can be run with one of its two absorbent canisters filled with potassium superoxide, which gives off oxygen as it absorbs carbon dioxide: 4KO2 + 2CO2 = 2K2CO3 + 3O2; in this mode the oxygen cylinder is a bailout, or to fill and flush the circuit at the start of the dive. This mode gives the set more duration underwater, but is dangerous and not to be risked by civilians because of the explosively hot reaction that happens if water gets on the potassium superoxide; whereas ordinary modern diverrebreather absorbents have been designed to avoid producing a caustic solution (commonly called "cocktail") if they get wet.
