    Abstract: An elective lock in the form of a set of pushbuttons which each have an alternately closing and opening contact. The contacts are connected in parallel with one another, so that switching off the lock is possible only by pushing solely the same buttons as are pushed in locking the device.

    Abstract translation: 一组按钮的形式的选择性锁，每个按钮具有交替的闭合和开放接触。 触点彼此并联连接，因此只能通过按下与锁定设备时相同的按钮来关闭锁定。

    Abstract: A motion sensitive alarm system having a sensing mechanism for actuating an alarm device in response to rotational motion, i.e., being tilted, as well as in response to linear motion. The alarm system includes a generally V-shaped conductive cage, a flexible rod having one end portion fixedly mounted, and an elongated cylindrical weighted member carried by the other end portion of the flexible rod. The cylindrical weighted member is disposed in a direction generally perpendicular to the direction of the elongated flexible rod. Accordingly, the weighted member begins oscillating in response to either rotational or linear acceleration. When the weighted member begins oscillating, it contacts the V-shaped conductive cage to thereby actuate the alarm device. The alarm device remains energized for a predetermined period of time and is then de-energized by a timedelay thermal relay.

    Abstract translation: 一种运动敏感报警系统，其具有用于响应于旋转运动（即，倾斜）以及响应于线性运动来致动报警装置的感测机构。 警报系统包括大致V形的导电保持架，具有固定安装的一个端部的柔性杆和由柔性杆的另一端部承载的细长的圆柱形加重构件。 圆筒形加重构件沿大致垂直于细长柔性杆的方向的方向设置。 因此，加权构件响应于旋转或线性加速度开始振荡。 当加权构件开始振荡时，它接触V形导电笼，从而致动报警装置。 报警装置保持通电预定时间段，然后由延时热继电器断电。

    Abstract: A warning device involving a rigid section of ladder is pivotally suspended from a tank, tower, building or the like and adapted to move slightly upon an intruder placing weight upon the section of ladder. Means are provided for biasing the ladder section in one direction, with the arrangement being such that upon an intruder placing weight upon the ladder, it overcomes this bias and actuates a warning device. The warning device may take the form of a switch which, when actuated, operates an alarm at a remote location, thus alerting a guard or the police of the trespass by the intruder. Significantly, all aspects of this device are inconspicuous, the motion of the ladder is slight, and the intruder in almost all instances will be unaware of the fact that his presence has been detected. Also, the arrangement resets itself automatically, and cannot be actuated by an accumulation of snow and ice.

    Abstract translation: 包括梯子的刚性部分的警告装置从罐，塔，建筑物等枢转地悬挂，并且适于在入座者将重物放置在梯子的部分上时稍微移动。 提供了用于在一个方向上偏压梯形部分的装置，其布置使得当入侵者将重量放在梯子上时，它克服了该偏压并致动了警告装置。 警告装置可以采取开关的形式，当被致动时，在远程位置操作警报器，从而警惕警卫或警察对入侵者的侵入。 重要的是，这个装置的各个方面都不明显，梯子的运动很小，几乎所有情况下的入侵者都不会察觉到他的存在已被检测到。 此外，该装置自动重置，并且不能由积雪积雪而起动。
