Data storage apparatus consisting of an array of RAM chips, with Hamming code checking for detecting double-bit errors. Address signals are fanned-out to the chips by way of driver circuits. Each driver circuit distributes an address bit to only two columns of chips (or in some case, just one column), so that is one of the driver circuits fails, no more than two chips in each row will be affected....

A hollow sphere ceramic flame spray powder is disclosed. The desired constituents are first formed into agglomerated particles in a spray drier. Then the agglomerated particles are introduced into a plasma flame which is adjusted so that the particles collected are substantially hollow. The hollow sphere ceramic particles are suitable for flame spraying a porous and abradable coating. The hollow p...

A substantially pure cordierite powder is applied by thermal spraying to components to provide a coating which protects the component against thermomechanical damage. The substantially pure cordierite powder is preferably made by fusing or premelting a cordierite forming mixture.

A high-temperature and thermal-shock-resistant thermal insulating coating based upon flame- or plasma-sprayed ceramic materials. The coating consists of several layer sequences essentially of the same materials. Each layer sequence contains at least one ceramic and one cermet layer, and/or one ceramic and one metal layer, and/or one cermet and one metal layer.

Process for the production of enhanced benzene, toiuene, xylene (BTX) yields from heavy hydrocarbon. A heavy hydrocarbon, such as kerosene or heavier hydrocarbon, is partially cracked in a conventional pyrolysis furnace. At the same time ethane is cracked at a high conversion in the same pyrolysis furnace. Upon partial cracking of the heavy hydrocarbon, the cracked effluent from the ethane is deli...
