Abstract: Apparatus for effecting differential pressure sensitivity of a pressure measuring device. A pressure sealed housing having a relatively high pressure inlet connection contains an expansion bellows having a relatively low pressure inlet connection. The bellows'' free end moves in proportion to the pressure differential between the high and low pressure supply. A lever connected to the free bellows end to outward of the housing, transmits the bellows output force to an external pressure measuring apparatus.

Abstract: A transducer for converting motion displacement into a digital electrical signal. A radiation impervious vane or shield member secured to a motion producing device moves conjointly therewith in a motion path extending intermediate a predetermined radiation sensitive or emitting array pattern and a radiation source or sensor. Movement of the vane acts to interrupt the light beam between the source and sensor and the extent to which the beam is interrupted is a measured function of vane displacement. Continual updated logic count analysis of the array units interrupted by vane position produces an electrical digital output signal for remote utilization in correspondence to the logic count.

Abstract: A motion responsive electrical control apparatus for emitting an electrical control signal incrementally variable in desired correlation to a path of given mechanical motion. The apparatus includes a rotatably regulated electrical controller for emitting signals correlated to the angular position setting of the controller regulator. A cam member pivotally mounted onto the regulator of the controller is arcuately biased into overlying engagement with a movable follower defining a motion path to which the apparatus is to respond. Presettably adjustable pitch members incrementally spaced along the path of follower motion effect desired incremental changes in cam pitch thereat affording corresponding change to the controller position setting.
Abstract translation: 一种运动响应电控制装置，用于发出与所给定的机械运动的路径有期望的相关性递增地变化的电控制信号。 该装置包括可旋转调节的电控制器，用于发射与控制器调节器的角位置设置相关的信号。 枢转地安装到控制器的调节器上的凸轮部件被弧形地偏置成与限定设备要响应的运动路径的可动从动件的上部接合。 可调节的节距构件沿跟随器运动的路径递增地间隔，影响凸轮节距的所需增量变化，从而提供对控制器位置设置的相应变化。
