    • A closed circuit hydraulic system includes a fluid reservoir, a hydraulic cylinder having a cylinder rod, a bidirectional variable displacement hydraulic pump that pumps fluid to either extend or retract the cylinder rod on demand, a flow control valve for relieving pressure between the variable displacement hydraulic pump and the cylinder, and a low pressure check valve between the variable displacement hydraulic pump and the fluid reservoir. Also included is a charge pump for charging the variable displacement hydraulic pump and an accumulator for saving extra energy and fluid from the hydraulic cylinder during the retraction of an extended cylinder rod and using that fluid and energy during the extension of the hydraulic cylinder to reduce a load on the charge pump. The flow control valve opens on demand to allow floating. The low pressure check valve opens when pressure at an inlet of the variable displacement hydraulic pump is low to provide additional fluid and pressure so as to avoid cavitation. A method for using the closed circuit hydraulic system is also provided.
    • 闭路液压系统包括流体储存器,具有气缸杆的液压缸,用于泵送流体以根据需要延伸或缩回气缸杆的双向可变排量液压泵,用于释放可变排量液压 泵和气缸,以及可变排量液压泵和流体储存器之间的低压止回阀。 还包括一个用于对可变排量液压泵进行充电的电荷泵和用于在延伸的气缸杆缩回期间从液压缸节省额外能量和流体的蓄能器,并且在液压缸延伸期间使用该流体和能量来减少 负载在电荷泵上。 流量控制阀按要求打开以允许浮动。 当可变排量液压泵的入口处的压力低时,低压止回阀打开,以提供额外的流体和压力,以避免气蚀。 还提供了一种使用闭路液压系统的方法。

    • A product delivery system and method are provided including an electromechanical vibratory conveyor which has a product conveying member, a vibrator for vibrating the product conveyor and a control system for controlling electronically the vibration of the product conveying member both statically and dynamically to optimize performance both with and without product on the product conveying member. The vibration of the product conveying member is tuned both statically and dynamically with a coarse tuning followed by a fine tuning. An improved pulse width modulation drive circuit for the vibrator includes vibrating frequency and amplitude varying devices for adjusting the frequency and amplitude of the vibrator for increased efficiency, optimized performance and reduction in energy consumption. Several redundant safety devices to safeguard the switching devices and the vibrator are also provided.

    • Packaging apparatus for packaging units in flexible sheet material with the units spaced longitudinally in a tube formed of a web of the material and with the tube sealed together between successive units. The apparatus includes a rotary sealing wheel carrying a series of sealing assemblies for sealing the tube, the sealing assemblies being uncoupled from the wheel and held at a hold position for again being released in timed relation to movement of the tube for sealing the tube between successive units. The apparatus also includes an electronic pulse counter or encoder driven at a speed proportional to the speed of the wheel to effect the release of a sealing unit in the event the passage of a unit to be packaged is not sensed by a photoelectric sensor when packaging the units in unprinted sheet material, or to control the placement of units to be packaged on a web of the material having registration marks preprinted thereon.
