Abstract: A safety-arming device for use in a highly maneuverable missile is disclo which takes into account lateral acceleration of the missile and selects the proper point in the trajectory after which arming of the missile warhead may safely proceed. The safety-arming device uses a series of electrical, mechanical, and electromechanical interlocks to insure that premature arming of the missile warhead does not occur.

Abstract: An optical notch filter having a suspension of small absorbing particles which blocks a narrow band of frequencies. The small absorbent particles are suspended as a colloidal system which can have either a solid, liquid or gas as host material. The absorbing particles can be incorporated in a solid matrix as a transmission filter or used on the surface of a mirror as a reflection filter. The filter can be tuned by an externally applied electric field or by applying hydrostatic pressure.

Abstract: Cylotetramethylenetetranitramine (HMX) or cyclotrimethylenetrinitramine () and one or more additives are dissolved in a solvent and drops of the solution are dispersed into hot air whereupon the solvent evaporates and fine particles of the explosive with the additive(s) intimately associated are formed. Reactive groups from the additives may then be utilized to facilitate wetting of the explosive by a binder or to chemically attach the explosive to the binder.

Abstract: A method of winding pulse transformers with copper tape or foil and bring out the leads directly from the winding on strip transmission line. This technique minimizes distributed inductance and leakage inductance of the leads connecting the transformer to external circuitry. It is particularly useful in high step-up ratio pulse transformers and/or pulse transformers in which the output pulse must have a very short rise time and fall time.

Abstract: A garment providing an emergency source of breathing gas is disclosed which utilizes small diameter tubing to form a reservoir for storage of high-pressure gas. A mask and pressure regulator attached to the reservoir enable a user to tap the stored gas. The tubing reservoir may be incorporated in the fabric of the garment, or retained between layers of the garment. A lightweight shielding layer protects the user against injury caused by accidental rupture of the high-pressure reservoir.
