Abstract: A method of manufacturing an impact-resistant material is described. Embodiments of the method includes hydrating a reinforcing material, which can be, for example, a fabric comprised of para-aramid fiber, infusing the hydrated reinforcing material with a resin, and curing the infused reinforcing material. Certain embodiments include hydrating the reinforcing material by exposing the reinforcing material to humidity and infusing the material by with a prepolymer-based diisocynate, for example, methylene diphenyl 4, 4?diisocyanate.

Abstract: To make an identification card, an individual is placed in front of a retroreflective screen, and faces a camera which has a semi-transparent mirror disposed at an angle of 45.degree. in front of its principal objective lens. A card, bearing data identifying the individual, is placed in the camera in registry with a second objective lens whose axis is disposed at right angles to the axis of the principal lens and at 45.degree. to the mirror. When the shutter between the principal lens and the photosensitive material in the camera is tripped, flash mechanisms cause the image of the card to be transmitted by the mirror to the screen and back through the principal lens onto a frame of the photosensitive material, where it forms a homogeneous background, and simultaneously cause the image of the individual to be photographed through the principal lens onto the same frame of photosensitive material.
