摘要： An electro-hydraulic system capable of high speed and precision timing, is disclosed, particularly adapted to the opening and closing of the intake and exhaust valves of an internal combustion engine under computer control. The actuator is powered by pressurized crankcase oil which is discharged on the engine valve stems for lubrication. The system employs hydraulic cushioning to reduce engine valve seating velocity, and recovers energy on the return stroke of the valve to improve efficiency. High speed is achieved by rapid de-energization of electromagnets which hold the fluid control valves closed against the force of the pressure of the hydraulic supply. These electromagnets latch the valves in their most power-efficient mode, that is, with the magnetic circuit gap at or near zero.

摘要： A safety guard for the cutting edge of a razor has a multiplicity of closely spaced apart relatively thin metal filament guard members fitted over the cutting edge of the razor or razor blade. The ends of the guard members on each side of the razor cutting edge are interconnected in close proximity to the cutting edge either by securing the ends to each other or by securing them to a respective elongated mounting strip. The safety guard is either permanently or removably secured to the razor.

摘要： A drive roller and a driven, braked, retard roller are juxtaposedly positioned along the path of documents being transported beyond a document feeding mechanism to provide passage of only one document at a time. The retard roller is carried on an arm which is swingable on a pivot and lightly spring loaded against the drive roller, such arm being placed and positioned at a certain angle rearward of a line extending perpendicular from the document, this angle being larger than the friction angle of document against document, but smaller than the friction angle of document against roller. A single document will pass between the rollers with both rollers rolling at the same speed, whereas when two documents attempt to pass between the rollers at the same time the second document will be retarded by the retard (braked) roller. When both the retard roller and the second document have come approximately to a near stop or standstill, such attitude is sensed at the retard roller, and the retard roller is lifted off or swung away from the documents to give the first document a head start, whereupon the retard roller is re-engaged after a certain short period of time to start the second document on its journey.
摘要翻译：驱动辊和被驱动的制动缓冲辊沿着被传送超过文件进给机构的文件的路径并置定位，以便一次仅提供一个文件的通过。延迟辊承载在可枢转的臂上，并且轻轻地弹簧装载在驱动辊上，该臂被放置并定位在垂直于文件延伸的线的后方的一定角度处，该角度大于摩擦文件对文件的角度，但小于文件对辊的摩擦角度。单个文件将在辊之间通过，两个辊以相同的速度滚动，而当两个文件同时尝试在辊之间通过时，第二个文件将被延迟（制动）辊延迟。当延迟辊和第二文件两者都大致接近停止或停止时，在延迟辊处感测到这种姿态，并且延迟辊被提升离开文件或从文档摆脱以给予第一文档的头开始，于是延迟辊在一段短时间之后被再次啮合，以便在行程上启动第二个文档。

摘要： A plurality of drive rollers, flexibly supported, are positioned along the inside track of a document transport passageway to drive the documents therealong, and a plurality of idler rollers, in opposed relationship to the drive rollers, are positioned along the outside track of the passageway. Each of the drive rollers and the idler rollers is supported from a pivot pin offset from the center of the roller to permit the roller to be canted by reason of gravity and elastic force, and thereby drive the documents in a forwardly and downwardly direction against a fixed edge guide to insure straight and longitudinal travel of the documents at a predetermined level along the passageway.

摘要： A light valve has a pair of rotating vanes for controlling the cross section of a light beam passing between the vanes. The vanes rotate on corresponding shafts, each controlled by its own integral motor. Separate feedback control systems produce electrical control signals to each motor for rotating each shaft independently of the other to control the desired phase angles of the vanes. In one embodiment, both motors are permanent magnet direct current servo motors in which the wound armature is an integral part of each shaft. A stationary magnetic field generated by permanent magnets is common to both motors. Power is supplied to each armature by a pair of thin, parallel, flexible, electrically conductive strips extending from an end of each shaft. The conductive strips reduce the torque on the shaft when twisted during operation. In one embodiment, the control system produces a calibrated digital control signal from a PROM representing the desired phase angles of the rotating blades. The digital signal is converted to analog control signals compared with position feedback signals from the rotating blades and damping signals produced by blade velocity feedback signals. Error signals fed to variable gain amplifiers control the positions of the vanes. Whenever new commands are input to the variable gain amplifiers, amplifier gain is temporarily switched to a high gain mode, and after the phase angle of the shaft has stabilized, the amplifier gain is switched back to a low gain mode. The separate motors and their servo systems speed up response time and substantially reduce any tendency toward oscillations.
摘要翻译：光阀具有一对旋转叶片，用于控制通过叶片之间的光束的横截面。叶片在相应的轴上旋转，每个叶片由其自身的积分马达控制。单独的反馈控制系统向每个电动机产生电控制信号，用于独立于另一个转动每个轴以控制叶片的期望的相位角。在一个实施例中，两个电动机都是永磁直流伺服电动机，其中绕线电枢是每个轴的一体部分。由永磁体产生的固定磁场对于两个电动机是共同的。通过从每个轴的端部延伸的一对薄的，平行的，柔性的，导电的条带向每个电枢供电。导电条在操作过程中扭曲时减小轴上的扭矩。在一个实施例中，控制系统从表示旋转叶片的期望相位角的PROM产生校准数字控制信号。与来自旋转叶片的位置反馈信号和由叶片速度反馈信号产生的阻尼信号相比，数字信号被转换为模拟控制信号。馈送到可变增益放大器的误差信号控制叶片的位置。无论何时向可变增益放大器输入新的命令，放大器增益暂时切换到高增益模式，并且在轴的相位角稳定后，放大器增益将切换回低增益模式。单独的电机及其伺服系统可加快响应时间，并大大减少任何振荡的趋势。

摘要： A header member containing an air chamber is positioned above each pocket of a document sorter, the air chamber having an upwardly directed inlet port and a plurality of downwardly directed outlet ports downstream of the inlet port. An air supply nozzle is positioned below the inlet port to blow air into the air chamber, the air then flowing out of the chamber through the outlet ports. The supply of air into the chamber is interrupted when a document passes between the inlet port and the supply nozzle, and the air flow is resumed when the document passes the inlet port, the air flowing from the outlet ports blowing the document downwardly, out of the path of the succeeding document, and into the pocket of the document sorter.
