    Abstract: A chip breaker drill bushing assembly (11) for a fluted drill bit (37) is disclosed. The assembly comprises a drill bushing housing (13) and a sleeve (15). The drill busing housing (13) includes a body (17) and an outwardly protruding guide shaft (19). The guide shaft has a smooth end (31) for tightly contacting the surface of a work piece (63) to be drilled. The sleeve (15) is located in the body (17) of the housing (13), in alignment with the guide shaft. The end of the sleeve (15) facing the tip (29) of the guide shaft (19) includes a chip breaker (41). The chip breaker (41) includes two spaced-apart teeth (46a, 46b) that are defined by two helical troughs (47a, 47b) that protrude into the sleeve (15). The two helical troughs (47a, 47b) are aligned with two longitudinal apertures (33) in the outwardly protruding guide shaft (19).

    Abstract: This invention relates to an improved solenoid operated fluid control valve particularly adapted for use as a vacuum control switch in a motor vehicle. One aspect of this invention is the provision of a coil assembly adapted to be wound and terminated using completely automated processes. This feature is provided through the use of a bobbin structure having protruding coil winding posts which position the start and finish ends of the coil wire. Terminal members are installed onto the bobbin and have terminal contact portions which can be folded onto the wire. Another feature of this invention involves means for reducing noise generated from actuation of the valve device. In conventional solenoid employing a "C" frame member, direct mechanical contact exists between the "C" frame member and another component of the magnetic circuit of the solenoid. In accordance with this invention, a thin annular layer of encapsulation material is provided between bores of the "C" frame member and the associated components of the magnetic circuit. This layer of encapsulation material prevents direct mechanical coupling with the "C" frame component, thus reducing noise generation. Means for calibrating the valve assembly according to this invention are also provided comprising driving a pole piece member into the coil bobbin bore as electrical and fluid control signals are applied. The pole piece motion is stopped once a change in state of the valve is observed, whereupon the desired physical parameters of the valve are provided.

    Abstract translation: 本发明涉及一种改进的电磁操作流体控制阀，特别适用于机动车辆中的真空控制开关。 本发明的一个方面是提供一种线圈组件，其适于使用完全自动化的工艺来卷绕和终止。 该特征通过使用具有定位线圈线的起始端和终端的具有突出线圈绕组柱的线轴结构来提供。 端子构件安装在线轴上，并具有能够折叠到导线上的端子接触部分。 本发明的另一特征涉及用于减少由阀装置致动所产生的噪音的装置。 在采用“C”框架构件的常规螺线管中，在“C”框架构件和螺线管的磁路的另一个部件之间存在直接机械接触。 根据本发明，在“C”框架构件的孔和磁路的相关组件之间提供薄的环状密封材料层。 这种封装材料层防止与“C”框架部件的直接机械耦合，从而减少产生噪音。 还提供了用于校准根据本发明的阀组件的装置，包括以电和流体控制信号施加的方式将极片构件驱动到线圈骨架孔中。 一旦观察到阀的状态改变，极片运动停止，由此提供所需的阀的物理参数。

    Abstract: A system for selectively positioning one end of a treadmill running machine at one of the plurality of locked positions in order to provide an inclined running surface. A support assembly having a ground engaging roller disposed between a pair of arms is pivotally connected to the frame of the treadmill for swinging movement between a retracted position adjacent the frame and one of a plurality of downward, extended positions. So that the treadmill may be easily raised and lowered to a desired operating position, a gas spring is provided for each of the arms of the support assembly. The upper end of each gas spring is securely connected to the frame, while the lower end is pivotally attached to its respective arm. To maintain the support assembly in one of its extended positions, a slide-tube assembly having a releasable clamping sleeve is associated with each of the arms and pivotally connected to the frame and arm to accommodate the swinging movement of the support assembly.
