摘要： A typewriter comprising a shiftable carrier supporting a rotatable type drum having a plurality of circumferentially extending rows of type characters thereon. Typing keys, when depressed, condition actuators and cause engagement of a power driven cyclic action clutch which drives a power bail to operate a conditioned actuator to rotate the type drum from any position it may be in to a new position to align a type character corresponding to the key depressed with the printing point. Certain of the keys, when depressed, position stops to limit axial movement of the type drum by the action clutch to align an appropriate one of the rows of type characters with the printing point. The action clutch also actuates a centralizer to accurately align the type drum prior to printing and, in addition, causes printing. A cyclic carrier shift clutch is engageable by the action clutch and by certain carrier shift control keys.

摘要： A type drum comprising a shell formed as an open network of rows and columns with type characters being formed at the intersections thereof, the shell being attached at one end by struts to a hub located within the shell and spaced therefrom and a combination of the type drum and structure for releasably mounting the drum onto a support such that the drum may rotate relative to its support.

摘要： A normally closed wafer thin switch, particularly intended for pilferage type burglar alarms, comprising a flat base plate of insulating material having an opening therein and a pair of leaf spring contacts attached to one peripheral portion of the plate and extending over the opening. Free ends of the contacts normally engage each other to complete a circuit. A raised tab on a first of the contacts overlies an opposite peripheral portion of the plate whereby, when an object is placed on or against the switch, the tab is depressed against the plate, causing opening of the switch.
摘要翻译：一种常闭晶片薄型开关，特别是用于盗窃型防盗报警装置，包括一个具有开口的绝缘材料的平板基板和一对连接在该板的一个周边部分上且在该开口上延伸的板簧触头。触点的自由端通常彼此接合以完成电路。在第一触头上的凸起突片覆盖在板的相对的周边部分上，由此当物体被放置在开关上或靠近开关时，突片被压靠在板上，导致开关的打开。

摘要： A power driven typewriter comprising a shiftable carrier supporting a rotatable and axially movable flexible type drum having a plurality of circumferentially extending rows of type characters thereon. Type keys, when depressed, each condition one each of two groups of actuators and cause operation of a power driven cyclically operable clutch which drives a power bail to operate the two conditioned actuators, one of which is effective to rotate the type drum from any position it may be in to a new position and the other actuator being effective to raise or lower the type drum from any position it may be in to a new position to thus align a type character corresponding to the key depressed at the printing position. Upon alignment of a selected type character, the type drum is flexed radially to cause an imprint. Means are provided to dampen torsional oscillation, wobble, etc. of the drum prior to imprinting.
摘要翻译：一种动力驱动打字机，包括支撑可旋转和可轴向移动的柔性滚筒的可移动托架，所述可旋转和可轴向移动的柔性滚筒在其上具有多个周向延伸的类型字符行。当按下压力时，键入键，每个状态分别是两组致动器中的每一个，并且使得动力驱动的可循环操作的离合器的操作，其驱动动力吊环以操作两个调节的致动器，其中一个致动器有效地从任何位置它可能处于新的位置，另一个致动器有效地将型式鼓从可能处于新位置的任何位置升高或降低，从而使对应于在打印位置处按下的键的类型字符对齐。在选定的类型字符对准时，类型鼓径向弯曲以产生印记。提供装置以在压印之前抑制滚筒的扭转振动，摆动等。
