摘要： A continuous process for electropolishing surgical needles. Surgical needles are mounted to an electrically conductive carrier strip. The carrier strip and needles are then moved continuously through an electropolishing bath and the needles are maintained in the bath for a sufficient period of time to effectively polish the needles.

摘要： A constant current annealing device for annealing a wire or surgical needle is disclosed. The device includes amplitude and time setting devices, such as thumb-wheel switches. A constant current source is connected to the current setting device. The constant current source is switchable, through a switch for example, in response to a timing signal to provide a constant current for a predetermined duration. A pair of spaced apart electrodes are clamped on the needle and a switching device is connected between the constant current source and the pair of electrodes. The voltage drop across the switching device varies to compensate for load variations, thus keeping the anneal current constant in the anneal ON mode. In the anneal OFF mode, where current is not provided to the needle, the switching device shunts a residual current away from the electrodes. The time setting device include a programmable logic controller (PLC) and a solid state relay to provide an accurate timing signal. A current measuring and monitoring device is connected to another PLC, which shuts down the annealing device after a predetermine number of alarms or after the constant current amplitude deviates by a predetermined amount.

摘要翻译：公开了一种用于退火线或外科用针的恒流退火装置。该装置包括振幅和时间设置装置，如拇指轮开关。恒定电流源连接到当前设置设备。恒定电流源可以通过开关例如响应于定时信号而切换，以在预定持续时间内提供恒定电流。一对间隔开的电极夹在针上，开关装置连接在恒流源和一对电极之间。开关器件上的电压降变化以补偿负载变化，因此在退火导通模式下保持退火电流恒定。在不向针提供电流的退火断开模式中，开关装置将剩余电流分流离开电极。时间设置装置包括可编程逻辑控制器（PLC）和固态继电器，以提供准确的定时信号。当前的测量和监测装置连接到另一个PLC，该PLC在预定数量的警报之后或在恒定电流振幅偏移预定量之后关闭退火装置。
