    • The present invention provides a heat sink for cooling a component. The component may be one of several components on a circuit board. The heat sink includes a tubular body and a plurality of internal fins. The tubular body has an interior surface and an exterior surface. At least a portion of the exterior surface being substantially flat. The plurality of internal fins extend from the internal surface and are generally symmetric around a center line of the tubular body. The substantially flat portion of the tubular body contacts the component to remove heat from the component. The heat sink may further include a plurality of exterior fins extending from the exterior surface of the tubular body.

    • The feed control device particularly suited for mounting on a hand held, power driven drain cleaning apparatus having an elongate rotatable snake (24) comprises a tubular housing (12) having a transverse wall (20) therein provided with a passage (22) for the snake (24), a pair of driving rolls (28, 30) mounted on the wall (20) for rotation about axes skewed relative to the housing axis (14) and a drive actuating roll (50) mounted on the housing (12) for radial displacement to engage the rotating snake (24) against the driving rolls (28, 30). The drive actuating roll (50) provides the inner end of an actuating drive unit (42) having an outer end engaged by a pivotal lever (74) on the housing (12) for displacing the actuating drive roll (50) against the snake (24). The actuating drive unit (42) is adjustable in length between the inner and outer ends thereof and is removably supported on the housing (12) and the lever (74) and outer end of the drive actuating unit (42) interengage to retain the parts of the actuating drive unit (42) in an adjusted position and to releasably hold the drive actuating unit (42) on the housing (12).
    • 特别适用于安装在具有细长旋转蛇(24)的手持式动力驱动排水清洁装置上的进给控制装置包括:管状壳体(12),其具有横向壁(20),该横向壁(20)设有通道(22),用于 蛇(24),安装在所述壁(20)上的一对驱动辊(28,30),用于相对于所述壳体轴线(14)倾斜的轴线旋转;以及安装在所述壳体(12)上的驱动致动辊(50) 用于径向位移以将旋转的蛇(24)接合在驱动辊(28,30)上。 驱动致动辊(50)提供致动驱动单元(42)的内端,其具有由壳体(12)上的枢转杆(74)接合的外端,用于使致动驱动辊(50)抵靠蛇 24)。 所述致动驱动单元(42)在其内端和外端之间的长度可调节,并且可移除地支撑在所述壳体(12)上,并且所述杆(74)和所述驱动致动单元(42)的外端相互接合以保持所述部件 所述致动驱动单元(42)处于调节位置并且将所述驱动致动单元(42)可释放地保持在所述壳体(12)上。
