<p>1,201,567. Crash restraint bags. EATON YALE & TOWNE Inc. 8 Nov., 1968 [8 Nov., 1967], No. 53128/68. Heading B7B. A crash restraint bag having an expanded volume V B at pressure P B is inflated from a reservoir of volume V R and an initial gas pressure P O , the gas flowing through a nozzle defining the minimum flow area and the product P o V R is equal to (1-Z<SP>2K/(1-K)</SP>)(2K-1/K)P B V B where K is the ratio of specific heats of the gas and where the quantity (1-Z <SP> 2K/(1+K)</SP>) is the ratio of the volume of the bag when inflated and the volume of the bag when t is infinity.</p> |
