    摘要: A data compression system and a method for compressing an alphanumeric message is disclosed in which a predetermined dictionary has entries represented by corresponding phrase codes, a phrase encoder encodes strings of at least one symbol in the alphanumeric message with phrase codes representing dictionary entries corresponding to the strings, and a statistical model encoder encodes at least a portion of the remaining symbols in the message using a statistical model based coding method.

    摘要: A liquid volumetric flow measuring apparatus is disclosed wherein a turbine or vane, flow straighteners therefor, and a rotating shaft mounted therewith, and a magnetic sender are all mounted as an integral unit in a U-shaped pipe trap, and a volumetric calculator is mounted in conjunction therewith. By a specific mounting of the turbine in the trap there is a dampening action causing the calculator to cease recording the flow immediately upon this stopping of the motion of the liquid through the trap. This construction provides a guard against any air which is pumped through the pipe being recorded as liquid in contradistinction to a gaseous fluid. The magnetic sender has a reed switch and a magnet which are specifically mounted so as to provide low angular momentum and reliability, at both high and low flow rates. The present invention is particularly useful in fuel delivery, wherein the liquid volumetric flowmeter is mounted within the system of the party to whom the fuel is delivered, and permits the party to accurately record the liquid fuel actually delivered, and to guard against being charged for air flow from the fuel supplier's pump.
