    • Methods and apparatus for stretching a plastic tape before the tape is joined in proper registration to a web of material in a machine. The apparatus comprises: means for advancing a leading portion of a flexible tape along a tape pathway; a guide that guides a lagging portion of the tape; a brake mounted to the guide and activatable to clamp a portion of the lagging portion of the tape at a first location; a sensor mounted to the guide and arranged to output a characteristic signal whenever the passage of a boundary of a structural feature of a particular type, repeatedly formed on or attached to the tape, is detected at a second location upstream of the first location; and a controller for causing the leading portion of the tape to be advanced a predetermined distance at regular spaced intervals of time and for causing the brake to clamp the lagging portion in response to the output of the characteristic signal by the sensor. The second location is selected such that the brake clamps the lagging portion while the leading portion is still being advanced, whereby a portion of the tape disposed downstream from the brake is stretched.
    • 在将胶带与机器中的材料卷正确对准之前,将胶带拉伸的方法和装置。 该装置包括:用于沿着带通道推进柔性带的引导部分的装置; 引导磁带的滞后部分的引导件; 制动器,其安装到所述引导件并且可激活以在所述第一位置处夹持所述带的所述滞后部分的一部分; 传感器,其安装到所述引导件,并且每当在所述第一位置的上游的第二位置处检测到重复地形成在所述带上或附着到所述带上的特定类型的结构特征的边界的通过时,输出特征信号; 以及控制器,用于使带的前端部分以规则间隔的间隔前进预定距离,并且用于使制动器响应于传感器的特征信号的输出而夹紧滞后部分。 选择第二位置,使得制动器在引导部分仍在前进时夹持滞后部分,由此布置在制动器下游的一部分带被拉伸。

    • An orbital shaker apparatus is provided, including a first shaft connected to a first bearing assembly at a first end and a mounting portion at the other. The first shaft is rotatable about a first shaft axis, and is connected to a motor. The second shaft has a bearing assembly on the mounting portion at one end and a platform at the other, and is aligned parallel to and offset from the first shaft by a distance. A counterweight rotor assembly is coupled to the mounting portion, and rotated by a belt driven by a pulley connected to the rotating shaft of a counterweight motor. The counterweight assembly includes two counterweight bearings, each having a counterweight wedge. The platform also includes supports for objects to be secured thereto. In use, as the counterweight rotor rotates, the second shaft, second bearing assembly, and platform describes a circular orbit with diameter 2R.

    • A wireless podium microphone (1) incorporates a body pack transmitter (26). The microphone (1) includes a microphone element (6) that is interconnected to a weighted base (2) by a deformable neck (3). The base (2) includes a first cavity (10) for housing electrical components associated with the operation of the microphone element (6) and a second cavity (21) in which the transmitter (25) may be securely mounted. A keyway (31) receives and constrains a button (30) that is affixed to the transmitter housing (27). Parallel guides (36, 37) are formed within the second cavity (21) and prevent lateral movement of the transmitter (26). An antenna guide (43) is mounted to the base (2) and permits the transmitter antenna (28) to be oriented to the desired antenna polarization.
