Abstract: The present invention is directed to a bar code symbol having stored thereon a data structure. The data structure includes a plurality of module elements. Each module element is configured as a bar symbol or a space symbol. The data structure includes a start character containing predetermined number of module elements. The predetermined number of module elements is configured in a predetermined pattern of bars and spaces. A data portion is configured to encode a single numerical value. The data portion has one termination data character and 0 to N Continuation characters, wherein N is an integer value. The data structure also includes a stop character.

Abstract: The present invention discloses a novel fuel structure for housing and delivering disparate cryogenic fuels to combustion zones in an aerospace vehicle. The tank comprises a plurality of containers having volumes that are separated by common wall bulkheads and which are arranged substantially side-by-side in conformance with the interior of the aerospace vehicle. A tank support structure positioned within the vehicle interior includes lengthwise supports as well as cross-wise supports, with the latter including openings within which the rear ends of the containers are supported. Fuel from the containers is delivered to the vehicle's combustion system via appropriate fuel lines carried by dome shaped end caps at the rear ends of the containers.

Abstract: A shock isolator having a spring members such as a belleville washer for supporting a static weight with the belleville washer toggleable between a support condition and a nonsupport condition with the belleville washer having a collapse force that is sufficiently high so that the belleville washer can support a static load without collapsing in order to normally maintain an elastomer damping material in a condition free or substantially free of static forces. When a dynamic force exceeds the collapse force of the belleville washer the belleville washer toggles to a collapsed condition leaving the elastomer to tensionally respond to both the static and the dynamic forces by expansion and contraction of the elastomer.
