    • A box, or carton, for carry-out restaurant foods, includes a collapsible box body formed out of cardboard. Upper and lower straps are anchored to the box side walls and the box end walls to span the box corners. These straps can be pulled away from the box walls to form loops for retaining or stabilizing beverage containers located in corner areas of the box. The straps engage the cups near the upper and lower edges of the cups, so that the cup is effectively restrained against tipping or sliding. The box is provided with a cardboard carrying handle that can be folded into the box when it is desired to fold the box walls into a flat package suitable for storage or shipment.
    • 用于进行餐厅食品的盒子或纸盒包括由纸板形成的可折叠盒体。 上下绑带固定在盒侧壁和箱体端壁上,以跨越箱角。 这些带可以从箱壁拉出以形成用于保持或稳定位于箱的拐角区域中的饮料容器的环。 带子接合杯子的上边缘和下边缘附近的杯子,使得杯子被有效地限制在倾翻或滑动中。 箱子上装有纸板托盘,当需要将箱壁折叠成适合于储存或运输的扁平包装时,该手提箱可以折叠成箱子。

    • A solid state tripping circuit for sensing overcurrent conditions in a circuit connecting a power source to a load circuit and for controlling the operation of a circuit breaker in series in the circuit. The tripping circuit is responsive to different levels of current flow in the protected circuit to actuate the circuit breaker to the open condition after a variable time delay. The duration of the delay time is a function of the ratio of the overcurrent sensed to the rated circuit current. Energy for operation of the tripping circuit is supplied directly by the sensing circuit to eliminate a separate power supply.
    • 一种固态跳闸电路,用于感测将电源连接到负载电路的电路中的过电流状况,并用于控制电路中串联的断路器的操作。 跳闸电路响应于受保护电路中不同电流的电流,以在可变时间延迟之后将断路器致动到断开状态。 延迟时间的持续时间是感测到的过电流与额定电路电流的比率的函数。 跳闸电路的工作能量由感应电路直接提供,以消除单独的电源。
