Title: Gasifcn. of solid fuels with steam - using heat from circulated molten iron heated by reaction with air in separate vessel
Inventor: NAKAMURA TAKEZO
IPC: C10J3/20
Filed: 1975-05-12
Abstract: Carbonaceous solid fuels are gasified by reaction with steam in an enclosed reactor in presence of molten iron, part of which is continuously circulated through a combustion furnace in which the carbon dissolved in the iron is burnt to raise the temp. The heat required for the endothermic gasifcn. reaction is supplied by combustion of the dissolved carbon, for which air can be used without diluting the product gas with nitrogen and without using pure oxygen. Ash from the fuel floats on the molten iron from which it is readily separated. Advantages of the known process using molten iron in a single reactor e.g. removal of sulphur by addn. of a little CaO to the fuel, and lower temps. than by use of molten slag, are retained.

Title: Correlator for contactless speed measurement - has one sensor perpendicular to pair in parallel for filterless harmonic suppression and band limiting
Inventor: MESCH FRANZ PROF DR ING
IPC: G01P3/80
Filed: 1975-10-03
Abstract: A correlator used in the contactless measurement of speed of moving objects using several measurement sensors is designed for elimination of frequency harmonics and band limiting to h.f. without the use of electronic filters. The basic method employs three sensors producing signals delayed w.r.t. each other according to the time taken for the object to traverse the distances between them. These signals are processed to produce correlation function signals which are combined to generate a signal whose frequency is proportional to the speed of the object. To achieve harmonic suppression and band limiting three pairs of sensors are used to produce three difference signals which are then processed.
