摘要： A preferred embodiment of a rotary tool reciprocating motion conversion attachment for a rotary power hand tool is described which is configured to be attached to a nose portion of the hand tool housing. The attachment has a rotary drive train in a housing that is connectable to the output shaft of the hand tool, the drive train driving a barrel cam having an exterior cam groove. A cam follower rides in the cam groove and produces reciprocating motion, with the cam follower being part of a cam follower assembly to which an implement holder is attached. The preferred embodiment has a cam groove configuration which causes the implement holder to move slower during a cutting stroke and faster during a return stroke, thereby tending to optimize the operation of the cutting implement. The preferred embodiment also includes a planetary gear set for reducing the rotational speed of the hand tool output shaft to reduce the speed of reciprocation of the attachment.
摘要翻译：描述了用于旋转动力手动工具的旋转工具往复运动转换附件的优选实施例，其构造成附接到手动工具壳体的鼻部。附件在壳体中具有可连接到手动工具的输出轴的旋转传动系，驱动系驱动具有外部凸轮槽的筒形凸轮。凸轮从动件骑在凸轮槽中并产生往复运动，凸轮从动件是凸轮从动件组件的一部分，工具保持器附接到凸轮随动组件。优选实施例具有凸轮槽构造，其使得工具保持件在切削冲程期间移动较慢并且在返回冲程期间更快地移动，从而趋向于优化切割工具的操作。优选实施例还包括行星齿轮组，用于降低手动工具输出轴的转速，以降低附件的往复运动速度。

摘要： A transportable pressurized coffee maker adapted to be used in and mounted to an automobile includes a coffee cup to receive brew which can be secured in tandem with the brewing chamber to prevent spills while driving. Safety features include temperature regulation, pressure release, interlocking safety cap, non-pressurized brewing chamber and a cool-to-touch outer shell. This coffee making apparatus also provides a high heat transfer immersion heating element compatible with the nominal 12 volt d.c. electrical system of most automobiles. This coffee making apparatus provides a sealable unit which can be operated while the automobile is in motion.
摘要翻译：适用于和安装在汽车上的可移动加压咖啡机包括一个咖啡杯，以接收冲泡，咖啡杯可以与冲泡室串联固定，以防止驾驶时溢出。安全功能包括温度调节，压力释放，互锁安全帽，非加压冲泡室和冷却触摸外壳。该咖啡制造装置还提供与标称12伏特直流电容兼容的高传热浸入式加热元件。大多数汽车的电气系统。该咖啡制造装置提供可在汽车运动时操作的可密封单元。
