    Abstract: A TAPE COMPRISING STRIPS OF BERYLLIUM COPPER SANDWICHED BETWEEN LAYERS OF MYLAR AND CONNECTED IN TANDEM TO SPACED SCANNING ASSEMBLIES OF A FACSIMILE TRANSCEIVER FOR MOVEMENT PAST AN OBJECT TO BE SCANNED. ONE END OF THE TAPE TERMINATES AT ONE OF THE SCANNING ASSEMBLIES AND THE OTHER END OF THE TAPE TERMINATES AT A ROTOR ASSEMBLY ABOUT WHICH THE TAPE AND SCANNING ASESMBLIES ROTATE IN AN ECCENTRIC PATH.

    Abstract: A facsimile transceiver including three optical scanners each of which carries its own light source for illuminating the copy as it is scanned. Also included are means for adjusting the optical axes of the scanners with respect to each other and printer contact means mounted on each scanner for marking recording paper when operating in the receiver mode.

    Abstract: The following specification describes a tracing scanning head having a photocell for sensing the presence of a pattern. The cell is supported on one shaft of a pair of coaxial shafts for movement transverse to the shaft axes. A pinion carried by the other shaft engages a rack carried by the one shaft for moving the photocell in response to rotation of the other shaft to compensate for the kerf or tool cutting width. A servo motor armature is fixed to the one shaft and rotates the one shaft and photocell to maintain the photocell angularly aligned with the line. A pair of easily readable knobs are provided at the upper end of the shafts to permit the offset to be easily determined. A preamplifier is carried by the one shaft to amplify low level photocell signals before they are transmitted over slip rings and brushes, and a neon bulb shielded by a metal ring casting lights the drawing pattern. A transparent shield depending from the casting protects the photocell lens. A pair of lamps cast indicia on the paper to enable the direction of scanning head travel to be easily ascertained.

    Abstract translation: 以下说明书描述了具有用于感测图案的存在的光电管的跟踪扫描头。 电池支撑在一对同轴轴的一个轴上，用于横向于轴的轴线运动。 由另一轴携带的小齿轮接合由一个轴携带的齿条，用于响应于另一轴的旋转而移动光电池，以补偿切口或刀具切割宽度。 伺服电动机电枢固定在一个轴上，并使一个轴和光电池旋转，以保持光电管与线路成角度对准。 在轴的上端设置有一对容易读取的旋钮，以允许偏移容易地确定。 前置放大器由单轴承载​​，以便在通过滑环和刷子传输之前放大低电平光电信号，并且由金属环铸造屏蔽的氖灯照亮绘图图案。 透明屏蔽由铸件保护，保护光电池透镜。 一对灯在纸上投射标记，以便能够容易地确定扫描头行程的方向。

    Abstract: A timing belt assembly trained about drive and idler pulley assemblies for supporting optical scanner units and moving the same in a continuous closed path upon rotation of the drive pulley assembly. The effective circumference of the drive pulley assembly is slightly greater than one-third the effective circumference of the timing belt assembly; the effective circumference of the idler pulley assembly is slightly less than one-third the effective circumference of the timing belt assembly; biasing means impose a lateral force on the timing belt assembly for maintaining the latter under substantially constant tension; and the cylindrical face means of the idler pulley assembly, about which the timing belt assembly, comprised of endless flexible tape means, is trained, has an axial extent at least equal to the width of the tape means.
