    • A copying machine for making large numbers of xerographic copies by first forming an electrostatic image of the subject matter to be copied on a first carrier unit, and then making a series of electrostatic images from that first image on a second unit, and printing a series of copies of the subject matter on successive copy sheets by the second unit. Retention of the initial image on the first electrostatically chargeable unit enables removal of the original sheet to be copied from the machine while the reproductions thereof are still being produced. A mechanism is also provided to maintain constant the optical path length of a tilting mirror photoreproduction device with flat platten during the tilting of the mirror.
    • 一种复印机,用于通过首先在第一载体单元上形成要复制的主题的静电图像,然后在第二单元上制作来自该第一图像的一系列静电图像,并打印一系列静电复印品 第二单位在连续复印件上的主题副本。 在第一静电充电单元上保持初始图像能够在仍在生产复制品的同时从机器中移除待复印的原稿。 还提供了一种机构,用于在反射镜倾斜期间保持具有平板的倾斜镜光复制装置的光路长度恒定。

    • A safety valve structure for use in the pneumatic supply line between an air compressor and an pneumatic tool operated thereby to sharply reduce the flow of air through the supply line in response to an abnormal decrease in pressure adjacent the tool below a predetermined value such as will occur upon breakage of the supply line. The safety valve structure includes a casing defining an axially extending cylinder having a piston reciprocable therein. A flow passage intersects and traverses the cylinder, and a valve element carried by the piston so as to be movable therewith is adapted to open and close the flow passage so as to control the movement of air therethrough. The piston is spring biased toward an inactive position in which the valve element is in its closed position; and a channel provided by the valve element permits a controlled minimum-flow of air therepast to the downstream side of the flow passage whenever the valve element is closed. A passageway interconnecting the downstream end portion of the flow passage and an end portion of the cylinder is adapted to permit the development of a pressure within the cylinder space effective to displace the piston against the biasing force of the spring into its active position in which the valve element is opened. Any sharp reduction in pressure in the downstream end portion of the flow passage enables the spring to return the piston and valve element to their inactive and closed positions, respectively.
    • 一种用于空气压缩机和由此操作的气动工具之间的气动供给管线中的气动供应管线的安全阀结构,其响应于工具附近的压力的异常降低而急剧减小通过供应管线的空气流动,低于预定值,例如 在供应线路断裂时发生。 安全阀结构包括限定具有可在其中往复运动的活塞的轴向延伸的气缸的壳体。 流路相交并穿过圆筒,并且由活塞承载以便可移动的阀元件适于打开和关闭流动通道,以便控制空气的流动。 活塞被弹簧偏压到阀元件处于其关闭位置的非活动位置; 并且当阀元件关闭时,由阀元件提供的通道允许在流动通道的下游侧将受控的最小空气流量限制到流动通道的下游侧。 将流路的下游端部和气缸的端部相互连接的通道适于允许在气缸空间内形成压力,以有效地使活塞克服弹簧的偏置力移动到其活动位置, 阀元件打开。 在流动通道的下游端部的压力的任何急剧下降使得弹簧能够将活​​塞和阀元件分别返回到它们的非活动和关闭位置。

    • A fuel tank inlet pipe including an inlet end and an outlet end opening downwardly into an associated tank. The inlet end of the pipe includes structure by which the outlet nozzle of a fuel discharge line may be coupled to the inlet pipe in fluid-tight sealed engagement therewith and also a fuel flow control valve for controlling the flow of fuel into the inlet pipe and operable, upon actuation of the valve, to move a valve member into closed position with a force generated by the pressure of the fuel delivered to the discharge nozzle. The valve includes a bleed port rendering the pressure of fuel delivered to the nozzle inoperative to move the valve member to the closed position and the bleed port itself has a valve member operatively associated therewith for closing the bleed port and rendering the line pressure of fuel delivered to the nozzle capable of moving the valve member of the control valve to its closed position in response to the tank and/or the inlet pipe being filled.
