Abstract: The present invention relates to a method and an apparatus for producing rapid cross-ignition of preferably elongate powder or pyrotechnic charges, such as the propellant charges in impulse motors for correcting the trajectory of shells, rockets and missiles. The cross-ignition is produced by initiation of an elongate, extremely fast-burning or detonating primer charge with an extremely low explosive force which has been arranged in contact with at least part of the periphery of the propellant charge. The primer charge forms a tube whose cross-ignition effect is advantageously complemented by an inner, slower burning powder core which is combusted with deflagration.

Abstract: The invention relates to a method, and to an arrangement, for optimizing the operation of a door closer at different phases of opening and closing of the door. The door closer is provided with a force transmission shaft (1) turning in accordance with the movements of the door and with a spring element (2) operationally connected thereto. The opening of the door takes place against the force of the spring element (2). According to the invention, at the closing phase of the door the energy of the spring element (2), exceeding the return force of the spring element (2) needed to accomplish the desired closing movement of the door, is recovered through simultaneous braking of the closing movement of the door for the main part of the closing movement. When the door is only somewhat open any more, preferably under 5.degree., a final force securing the closing of the door is accomplished by making use of said recovered energy. For putting the method into practice, the door closer is provided with rotor (4), stator (5) and energy storing device (7), arranged to serve as an electric generator or as an electric motor as required.
Abstract translation: 本发明涉及一种用于在门的打开和关闭的不同阶段优化门关闭器的操作的方法和装置。 门关闭器具有根据门的移动和与其可操作地连接的弹簧元件（2）转动的力传递轴（1）。 门的开口抵抗弹簧元件（2）的力发生。 根据本发明，在门的关闭阶段，弹簧元件（2）的能量超过了实现门的所需闭合运动所需的弹簧元件（2）的返回力，通过同时制动 门关闭运动的主要部分关闭运动。 当门仅稍微打开时，优选在5度以下，通过利用所述恢复的能量来实现确保门关闭的最终力。 为了实施该方法，门关闭器设置有转子（4），定子（5）和储能装置（7），其被设置为用作发电机或根据需要的电动机。
