Abstract: A clear, hollow cylindrical tube having an internal circuit board with LED lights provides a lighting and flashing illumination device. The LED lights may either all be illuminated at once, or have certain LEDs with constant illumination while other LEDs may be placed into a flashing mode. The power source for the lighting and flashing apparatus includes either standard or rechargeable batteries and a 12-volt external source. The 12-volt external source may also be used to recharge the rechargeable batteries. The cylinder has an upper collar with both magnetic and hook hanging mechanisms. The rechargeable LED lighting and flashing apparatus provides much more illumination than a flashlight using standard charging and lighting electrical parts.

Abstract: A neck seal for use in an emergency breathing apparatus has an interior and an exterior and is formed of an annular sheet of elastomeric material having a substantially central aperture for donning over a person's head. The substantially central aperture is sized appropriately for snug fitting around the person's neck so as to be sufficiently tight to prevent passage between the person's neck and the neck seal of fluid materials without choking the person. The neck seal is coated at least in part with parylene, to thereby prevent passage through the elastomeric material of NBC/CBR materials.

Abstract: Time delay apparatus for providing a firing action at the end of a predetermined time-delay period. It is used with a source of fluid under pressure, and defines a fluid-receiving chamber for accumulating the fluid when released from the source. A flow controller is connected between the source and the fluid-receiving chamber for providing fluid communication between the source and the fluid-receiving chamber. A triggering assembly initiates flow of fluid from the source through the flow controller and into the fluid-receiving chamber. A piston-form firing pin in the fluid-receiving chamber is actuated by shear pin release for movement to an actuating position for desired firing action when a predetermined pressure has accumulated in the fluid-receiving chamber at the end of the predetermined time-delay period.
