Paste<br />

connected in parallel. Since only a very small fraction of the electric<br />

energy employed is then actuated in the primer bridges (the bulk of the<br />

energy is dissipated in the lead wires), parallel connections require<br />

special high-energy-supplying blasting machines.<br />

Paste<br />

Pulverrohmasse; galette<br />

A nitrocellulose-nitroglycerine mixture for the solvent-free manufacture<br />

of W Double Base Propellants. It is obtained by introducing nitroglycerine<br />

(or diglycol dinitrate or similar nitrate esters) into a stirred nitrocellulose<br />

suspension in water. The mixture is then centrifuged or<br />

filtered off; it contains about 35% water; its appearance resembles<br />

that of moist nitrocellulose. The paste, containing materials such as<br />

stabilizers and gelatinizers, is manufactured to the double base powder<br />

by hot rolling and pressing without application of solvents.<br />
