Abstract: A method of making siloxane-based polyamides which includes at least one repeating unit represented by the formula ##STR1## wherein X is a linear or branched C.sub.1 -C.sub.30 alkylene chain; Y is a linear or branched C.sub.1 -C.sub.20 alkylene chain; DP is an integer having a value of 10-500; n is an integer having a value of 1-500. The method involves heating an intimate reaction mixture containing an olefinic acid and an organic diamine at a temperature greater than 100.degree. C. and forming an organic diamide; and thereafter reacting the organic diamide with a hydride-terminated polydimethylsiloxane in the presence of a hydrosilylation catalyst to form the siloxane-based polyamide.

Abstract: An improved vault door having a daylock and a relock mechanism is disclosed. The door is selectively locked and unlocked within a frame of the vault by operating a pair of combination locks mounted to the door front to slide a lock bar mounted to the rear of the door. The daylock mechanism includes a spring biased member which engages a cavity in a daylock extension attached to the lock. This engagement holds the lock bar in the unlocked position so the door may be swung within the frame without the lock bar impacting the frame. A keylock mounted in the front of the door may be turned to withdraw the member from the cavity so the lock bar can be slid to secure the door in the frame. The relock mechanism includes a pivotably mounted bar held in a horizontal position by a pin mounted to an attack plate that is displaceably mounted to a mounting plate on the rear of the door.
