摘要： 1347292 Treatment of waste pickle liquor WIRE SALES CO 25 May 1971 [24 Nov 1970] 16902/71 Heading C1A Waste pickle liquor is cooled to precipitate the ferrous salts contained therein after which said salts are filtered off and dissolved in water and the solution is then treated with sodium hypochlorite to precipitate ferric hydroxide which on heating is converted to Fe 3 O 4 . In the example waste liquor is cooled to 0‹C. in vessel 2 and filtered using, e.g. active charcoal, the recovered acid being recycled and the solids being dissolved in water and after a further filtration passed to vessel 6. In reactor 6 the ferrous salt solution, e.g. FeSO 4 , is treated with NaOCl to precipitate the iron content as ferric hydroxide which is filtered off and passed to an oven, or evaporator, (not illustrated) where it is converted to Fe 3 O 4 . The liquor from reactor 6, after separation of precipitated solids is passed via line 10 to evaporator 11 for recovery of the sodium salt, e.g. Na 2 SO 4 , produced as byproduct. Chlorine evolved in reactor 6 is either stored, or is passed into NaOH in vessel 9 to form NaOCI which is then used in precipitation of ferric hydroxide.

摘要： An electrical testing device has an electrically insulating housing with one projecting electrode and another insulated wire containing a second projecting electrode. A neon tube is included within the housing and gives a visual indication of voltage. The exposed electrodes are generally spade-shaped to permit introducing the same into the slots of a conventional receptacle to determine if the receptacle electrodes are live. In addition, the testing device also has an auxiliary electrode within a slotted portion of the housing.

摘要： A fence charging system includes a sensing circuit connected to a fence to be charged. The sensing circuit applies a harmless low voltage which normally maintains a fence charger below operating level so long as the fence is ''''unloaded'''' (has a high resistance in the absence of at least one animal grounding the fence). When the fence becomes ''''loaded,'''' the current drawn by the fence sensing system changes potential distribution in the fence charging system and permits the charger to operate normally, the fence charging system under such conditions impressing high voltage pulses on the fence at predetermined intervals so long as the fence remains ''''loaded.
摘要翻译：栅栏充电系统包括连接到要充电的栅栏的感测电路。传感电路应用无害的低电压，只要栅栏“卸载”（在没有至少一个动物接地栅栏的情况下具有高电阻），通常将栅栏充电器保持在操作水平以下。当围栏变得“装载”时，由栅栏感应系统抽出的电流改变栅栏充电系统中的电位分布，并允许充电器正常工作，栅栏充电系统在这种条件下以预定间隔在栅栏上施加高电压脉冲，从而只要栅栏保持“装载”。
