Automatic inflating lifesaving buoy
First Claim
1. An automatic inflating lifesaving buoy comprising a gas generating device, an inflatable bag and an electric cell or battery, the gas generating device being provided with the electric cell or battery at the rearward end and the inflatable bag at the forward end, the gas generating device being a substantially hollow body in which an electric ignition device is arranged adjacent to the electric cell or battery and/is electrically connected with the electric cell or battery and surrounded with a gas generating composition, and a spacer provided in contact with and in the forward direction of the gas generating composition, a multi-perforated partition plate provided in contact with or integrated with the spacer, another multi-perforated partition plate provided in the forward direction of the first multi-perforated partition plate and at an appropriate distance to form a chamber wherein a cooling agent is charged, and an outlet for supplying generated gas to the inflatable bag through the second multi-perforated partition plate.

Abstract
An automatically inflating lifesaving buoy device having a gas generating device in which the gas generating composition is ignited by an electric ignition device powered by a water-activated electric cell or battery. The gas then generated is cooled as it flows into an inflatable bag to form the lifesaving buoy.
