Calculating unit having adder blocks, each having single adders, a carry input, a carry output, and a carry pass output, wherein a signal at the carry pass output is indicative of a carry passing through the adder block. In more particular embodiments, the backhaul link may use a DOCSIS link, the radio signal stream can be received using a Common Public Radio Interface, and the radio signal stream may include sub-streams transported through segmented channels over the backhaul link. Another aqueous titanium oxide-dispersed sol comprising brookite-type titanium oxide particles dispersed in water, said titanium oxide particles having an average particle size of not more than 0. Once the relatively smaller hydrocarbons pass through the flux cartridge membrane into the flux cartridge, the effluent can be routed to a second separator annulus. The supporting metal of the outer surface of the bit leg may also have an upper cylindrical section and a lower tapered section. The machine includes at least one fixing device for fixing of a toner image on the substrate, having at least one heater for melting the toner image, past which the substrate can be guided by a transport device which has one or more transport elements.
