    • A circuit interruption apparatus for a power circuit having a power source and a load includes a termination mechanism for interconnection with the power source and the load; a circuit interrupter having a line terminal and a load terminal for interrupting the power circuit between the power source and the load; and a pivot mechanism for pivoting the circuit interrupter between a first position wherein the line terminal and the load terminal are interconnected with the termination mechanism, and a second position wherein one of the line terminal and the load terminal is disconnected from the termination mechanism. Alternatively, a circuit interruption apparatus for the power circuit may include a line termination mechanism for interconnection with the power source; a circuit interrupter having a line terminal and a load termination mechanism for interconnection with the load; and a pivot mechanism for pivoting the circuit interrupter between the first position and the second position. Alternatively, a circuit interruption apparatus for a power circuit may include a circuit interrupter having a trip lever mechanism for tripping open the power circuit and for interrupting the power circuit between the power source and the load; and a fuse in series with the circuit interrupter between the power source and the load for interrupting the power circuit therebetween and having a striker pin for engaging the trip lever mechanism and tripping open the power circuit whenever the fuse interrupts the power circuit.

    • An apparatus for moving a longitudinal film strip carrying positive or negative images and having spaced perforations along parallel longitudinal edges of the strip in a longitudinal pocket, and comprising a longitudinal planar member having first and second parallel longitudinal edges and a plurality of spaced, flexible gripping members extending out of the plane of the longitudinal member. The gripping members engage in the spaced perforations along parallel edges of the film strip when the planar member is positioned adjacent the strip in an overlying manner within a longitudinal pocket holding the strip. In a preferred embodiment, the gripping members are triangular and are arranged in spaced parallel row adjacent the first and second edges.
    • 一种用于移动纵向胶片带的装置,其带有正或负图像并且在纵向凹槽中沿着条的平行纵向边缘具有间隔开的穿孔,并且包括具有第一和第二平行纵向边缘的纵向平面构件和多个间隔开的柔性夹持 构件延伸出纵向构件的平面。 当平面构件在保持条带的纵向口袋内以覆盖的方式邻近条带定位时,抓握构件沿着胶片条的平行边缘接合间隔的穿孔。 在优选实施例中,夹持构件是三角形的并且以与第一和第二边缘相邻的间隔开的平行排列布置。
