摘要： The invention is a unibody key with lateral grooves on one side or both sides of the shank of the key. The lateral grooves are of an irregular pattern and are cut at a depth such that the key can be snapped off along the lateral groove. The snapped-off portion ofthe key can be inserted in a lock. By inserting the snapped-off portion in the lock, only a key which will mate with the irregular pattern of the snapped-off portion will give proper alignment for a key to open such lock. By such operation, the key necessary to open the lock is easily, quickly and effectively changed.
摘要翻译：本发明是在钥匙的柄的一侧或两侧具有横向槽的单体键。横向槽是不规则图案，并且被切割成一个深度，使得钥匙可以沿着横向槽被卡扣。钥匙的卡扣部分可以插入锁中。通过将锁扣部分插入锁中，只有与卡扣部分的不规则图案配合的钥匙才能正确对准钥匙以打开这种锁定。通过这种操作，打开锁的必要键很容易，快速有效地改变。

摘要： A programmed steering and cutting blade control apparatus for self-contained lawn mowers with a nylon tape having rectangular members disposed on the upper and lower surfaces of the nylon tape which extends between two reels where the rectangular members actuate micro switches disposed below the nylon tape and actuate micro switches disposed above the nylon tape where such upper micro switches are connected to a plate which is reversible so as in one instance to reverse the plate and the micro switches are disposed away from the nylon tape and not actuated. Two lower micro switches actuate a turning wheel motor and a third micro switch actuates a brake. The upper micro switch actuates the cutting blades. The movement of the programmed nylon tape is synchronized with the movement of the drive wheels to ensure the self-contained lawn mower moves along the preplanned route.
摘要翻译：一种用于独立式割草机的编程转向和切割刀片控制装置，其具有设置在尼龙带的上表面和下表面上的矩形构件的尼龙带，其延伸在两个卷轴之间，其中矩形构件致动设置在尼龙带下方的微型开关，启动设置在尼龙带上方的微型开关，其中这种上部微型开关连接到可逆的板，因为在一种情况下可逆转板，并且微型开关远离尼龙带设置并且未致动。两个下部微动开关致动转轮马达，第三个微动开关致动制动器。上部微动开关致动切割刀片。编程尼龙带的移动与驱动轮的移动同步，以确保独立的割草机沿着预先计划的路线移动。
