Abstract: A remotely operated mechanism is used to mount an engine in a compartment ere connections between the engine and compartment are difficult to access or see. The mechanism comprises a mounting adapter which is fit to the engine and which mates to a mounting block connected to the floor of the compartment. The adapter has a ridge, an adapter bore through the ridge, and a facial flat on either side of the ridge. The mounting block has a channel whose sides closely receive the ridge, and has two block bores along a common axis. Mounting flats on the block interface with the adapter's flats when the block and adapter are fully engaged. To fasten the adapter to the mounting block, a plunger is biased to translate in one of the block bores until a keeper of the plunger fits closely both in the ridge bore and the other block bore. The plunger position is controlled by a cable connected thereto, and a locking device on the cable releasably fixes the cable in a selected position.

Abstract: A military tank is equipped with an armored box structure in the space nolly occupied by the gun turret. A lid on the box structure is raisable to an inclined position suitable for the firing of a missile carried on the lid undersurface. As the missile is fired an explosive-charged line attached to the missile rear end is drawn out of the box structure onto the terrain (along the missile line-of-flight). By exploding the line charges it is possible to detonate enemy land mines in the vicinity of the charged line.
