    • A multiple switch automatic reset timer in which the switches are located in the back of the timer and have operators angularly spaced about a main bearing axis. A clutch operator is also angularly spaced from the switch operators. A spring return timing gear on the main bearing axis drives a spring tensioner also carried on the main bearing axis. This stores power in the spring which is released at the timed-out point for driving a cam wheel carried on the main bearing axis. This actuates the switch operators and also releases the clutch allowing the timing gear to reset. The cam wheel is maintained in the timed-out position by a latch engaging the spring tensioner. This latch is released by a solenoid operated wheel carried on the main bearing axis. This wheel may also operate the clutch and one or all of the switches. The wheel configuration determines the type of action given by the timer. Provision is made for on delay, off delay, interval, instantaneous switch operation and many other combinations.

    • A mechanical thruster for positively separating two releasably joined components under a controlled time delay. The thruster is particularly useful for mechanically opening canisters containing survival kits as they are being dropped from an airplane to a target. The thruster comprises an adjustable mechanical timing means which is actuated when a pin is pulled from it. After a predetermined time delay, the timing means actuates a plunger mechanically associated with it, which plunger dislodges a locking piston. This locking piston in locking position mechanically holds a thruster body about a barrel of the device. Once the locking piston is displaced, the thruster body is propelled away from the barrel. When the mechanical thruster is secure to the main body of a container, and the thruster body is attached to the container lid, separation of the thruster body from the rest of the thruster causes the container lid to separate from the container, making it possible for the container contents to be removed from the container. The device according to the present invention can be used in place of known, pyrotechnic thruster devices.
    • 一种机械推进器,用于在受控的时间延迟下正向分离两个可释放地连接的部件。 推进器特别适用于机械打开包含生存套件的罐,因为它们从飞机上落下到目标。 推进器包括可调节的机械定时装置,当销从其被拉动时被致动。 在预定的时间延迟之后,定时装置启动与其机械相关联的柱塞,该柱塞移动锁定活塞。 锁定位置的锁定活塞将推进器主体机械地保持在装置的桶周围。 一旦锁定活塞移动,推进器主体被推离远离枪管。 当机械推进器固定在容器的主体上并且推进器主体附接到容器盖上时,推进器主体与推进器的其余部分的分离使得容器盖与容器分离,使得可以 从容器中取出的容器内容物。 根据本发明的装置可以用于代替已知的烟火推进器装置。
