a fraction that may be reduced to the simple form if there is no leakage during the passage of the air, because in that cause p2 v2 = p1 v1. Lastly, if W1 is the net disposable force on the shaft of the compressed air motor, the efficiency of this engine will be, and the product of these three partial efficiencies is equal to W1/W, the general efficiency of the transmission.
It ran on seventy per cent hydrogen peroxide, first developed as a fuel back in the 1940s for the pumps of the V2 rockets that tried to win the Second World War for Germany. When hydrogen peroxide comes in contact with a catalyst, such as permanganate of potash, it breaks down into oxygen and water. But the water is in the form of high-pressure steam, which is used in engines.

The distributor box also contains on opposite sides shorter rails, u4, adapted to engage the lower ends of the matrices, to hold them in position as they are lifted. The lifting finger V is mounted on a horizontal pivot in one end of an elbow lever mounted on pivot v2 and actuated by a cam on the end of one of the carrier-screws, as shown in Figs. 2 and 15.
