  • Interesting fact: Spirit of proof strength was the technical standard by which strength was measured until 1st January, 1980. Hundreds of years ago, spirit of this strength was proved when Whiskey and gunpowder were mixed and ignited. If the gunpowder flashed, then there was enough Whiskey in the mixture to permit ignition. Such Whiskey was held to have been proved - i.e. "tested". If the spirit was weaker than this, then ignition did not take place and the Whiskey failed the "test". The amount of black powder used was the same amount as was, and indeed still is, used to "proof" the barrels of smooth-bore fire-arms.

    • n ignition In internal-combustion motors, the setting fire to the mixture of air and hydrocarbon vapor in the cylinder, so that the air shall expand and increase its pressure and perform the work required. Ignition is mainly effected, in modern motors, by an electric spark which jumps across a gap between terminals and in so doing raises the temperature of the mixture to the igniting-point. Such electric ignition may be by the jump-spark system, or by the make-and-break system. In the jump-spark system, the terminals on the secondary circuit of a Ruhmkorff or induction-coil are used. The current is made and broken on the primary or battery circuit, and this sends a secondary current of high intensity through the secondary line, in which are the gap-terminals. The primary make-and-break effect may be either by mechanical or by electrical vibrators, timed at will by the revolution of the motor-shaft. The hammer-break or arc system ignites by causing a flowing primary current to be mechanically interrupted by the separation of two contacts in the circuit. The current arcs across the break until the gap becomes too wide and the arc sets fire to the mixture around it. The make-and-break gives a ‘fat’ or copious spark, but considerable battery-power is needed; the jump-spark gives a tenuous high-tension spark, with less battery-power. Magneto-electric machines or small dynamos are much used for electric ignitions. Ignition may also be effected by compressing the mixture and at the right time allowing it to enter a hot tube of refractory material heated to redness by an exterior flame; or simple compression within the hot walls of the containing-chamber will fire an easily ignited mixture.
