摘要： The invention relates to a system for preventing collisions of an automobile with obstacles. Sensors mounted in the automobile detect the area surrounding the vehicle. The signals of said sensors are evaluated by a data processing device in order to calculate the available obstacle-free driving space. Other sensors additionally detect the position of all movable vehicle parts (e.g. a trailer) and the dynamic parameters of the current driving situation (e.g. speed, steering angle, etc.). Based on said data, the driving speed required during the following time intervals in order to continue driving is calculated in advance by the data processing device and compared with the actually available obstacle-free driving space that has been detected. Said comparison provides early forecast regarding a possible collision. The driver is warned of a possible collision danger by corresponding warning devices and can consequently react in time. In critical situations (e.g. high driving speed), direct interventions in the control of the vehicle by the data processing device can take place to assist the driver.

摘要： A method and means for obturating a stub case on the barrel wall of a firearm is disclosed having an annular bead located near the top of the stub case wall dimensioned so as to provide an annular gap between the bead and the barrel wall thereby throttling the streams of gas flowing back after detonation. The gas is thus permitted to expand and is deflected in a Y-shaped packing ring so that the radial pressure of the gas against the oblique arm of the packing ring provides a satisfactory obturating action.
