摘要： A control system for a vacuum milking system, and a method of controlling vacuum in such milking system. The system comprises an electric vacuum pump motor, a vacuum transducer for providing an output signal that varies as a function of changes in vacuum in the milking line and a variable frequency drive (VFD) connected to the vacuum pump motor and the transducer for controlling the speed of the motor. The VFD varies the frequency of the power signal it provides to the motor as a function of deviation between the output signal from the transducer, which the VFD is programmed to recognize as representative of vacuum, and a setpoint representative of vacuum.

摘要： A method for coating the internal threads of a fastener includes a rotatable base for holding the fastener, and an applicator having a discharge orifice extending through its side wall which contacts the internal threads at a single point of tangency, the axis of the applicator being offset from the rotational axis of the base. Thus, an induced side load force is created at the point of tangency for effecting the pressing of discharged sealant into the roots of the threads. Differently sized internally threaded elements can be coated in accordance with the invention while using the same sealant applicator.

摘要： A punch, apparatus and method for forming opposing holes in a hollow part, and a part formed therefrom. The punch includes an end portion adapted to pierce an entry hole and bend material around the entry hole to form a retained slug along an inner edge of the entry hole. The punch also includes an enlarging portion adapted to enter the entry hole after the end portion to enlarge the entry hole by bending the slug and additional material towards the interior of the part. The punch has a length greater than a cross-section of the part such that further advancement of the punch through the part punches an exit hole in the part opposite the entry hole.
摘要翻译：一种用于在中空部分中形成相对孔的冲头，设备和方法，以及由其形成的部分。冲头包括适于刺入进入孔并围绕入口弯曲材料的端部，以沿着入口孔的内边缘形成保持的塞子。冲头还包括适于在端部之后进入入口的扩大部分，以通过将块塞和附加材料朝向部件的内部弯曲来扩大入口孔。该冲头的长度大于部件的横截面，使得冲头穿过部件的进一步前进冲击与入口孔相对的部分中的出口孔。
