Abstract: An alternator assembly for use with munitions fired from rifled bores in which both the rotor and stator are juxtaposed along the axis of the munition member and do not exceed the bore-size diameter of the member. Electrical energy is thus generated as the member or round traverses the bore, which energy is used for powering a munition tracking system and/or arming a fuse contained therein.

Abstract: An improved process is provided for the preparation of polyhydroxybutadienes (hydroxy-containing butadiene homopolymers) which comprises injecting an aqueous solution of alkali metal sulfite or bisulfite into the polyhydroxybutadiene solvent recovery section to prevent fouling.

Abstract: This alternator includes a stator comprising an armature winding and a rotor comprising a permanent magnet field. A sleeve is located between the rotor and stator and comprises on its periphery alternating ferromagnetic and nonmagnetic segments. When the ferromagnetic segments are aligned with the poles of the stator, the flux linkage between the rotor and stator is maximum. When the nonmagnetic segments are aligned with the stator poles, the flux linkage is a minimum. The sleeve is shiftable through 90 electrical degrees by means of a motor. The output of the alternator may be regulated between maximum and minimum values by so shifting the sleeve.
