"It is my heart-warmed and world-embracing Christmas hope and aspiration that all of us, the high, the low, the rich, the poor, the admired, the despised, the loved, the hated, the civilized, the savage (every man and brother of us all throughout the whole earth), may eventually be gathered together in a heaven of everlasting rest and peace and bliss, except the inventor of the telephone. "

Mark Twain ; Christmas greetings, 1890

NumberTitleIssue Date
4541367Combustion and pollution control system
A controlled amount of a fluid (steam or water or a solution of water plus additives) is injected into an internal combustion engine to improve combustion, efficiency, and to reduce emissions. The amount of the fluid injected is controlled in response to ...

4131134Fluid flow regulator
A fluid flow regulator controls the amount of fluid flow or pressure of the fluid flowing through the regulator by producing an impedance to flow through the regulator which varies in relationship to the pressure differential across the regulator and whic...
12/26/1978
4112892Combustion control system for adding fluid above the butterfly valve
A combustion control system adds fluid to the air fuel mixture of the induction system of an internal combustion engine in response to the engine's need for the added fluid to improve combustion, to increase power, to improve efficiency, and to reduce emi...
