摘要： An electric fence controller (20) interconnected to electric fence terminals (136, 138) by a three terminal spark gap arrangement (140) one terminal (142) being interconnected to the fence hot terminal (136), a second terminal (144) being interconnected to the fence ground terminal (138) and a third terminal (146) being interconnected to utility ground (48). High voltage surges on the electric fence will thus be diverted either to the local fence ground terminal (138) or to the utility ground (48) whichever ground has the least resistance to ground thereby assuring an effective ground so as to prevent damage due to lightning strikes.
摘要翻译：一个电气围栏控制器（20），其通过三端火花塞装置（140）与电气围栏端子（136,138）互连，一个端子（142）互连到栅栏热端子（136），第二端子（144）互连到栅栏接地端子（138）和与公用地面（48）互连的第三端子（146）。因此，电篱笆上的高压浪涌将被转移到本地篱笆接地端子（138）或公用地面（48），无论地面抵抗地面最小，因此确保有效接地，以防止由于闪电造成的损坏罢工。

摘要： An arrow and method of making it. The arrow has a hollow arrow shaft, a single piece adaptor having one end with an outer diameter and a cylindrical bore with an inner surface adhesively engageable about a first end of the shaft and an externally threaded opposite end. An inclined surface surrounds the externally threaded end and tapers inwardly from the outer diameter of the one end towards the bore. The inclined surface has a diameter greater than that of the external threads. The external threads and inclined surface receive and retain an arrow point with internal threads and inclined surface so that impact forces are not transmitted to the inner surface of the shaft. A balance pin has a shaft portion received in the arrow shaft, and a head portion interconnected to one end of the balance pin shaft portion. The head portion has a diameter greater than the shaft portion outer diameter and smaller than the inner diameter of the cylindrical bore. The method comprises the steps of: providing the end adapter and balance pin, inserting the balance pin shaft portion in the shaft opening until the balance pin head portion abuts the arrow shaft, adhesively engaging a portion of the inner surface of the adaptor bore with the outer surface of the shaft, threading an arrow point with an inclined surface on the externally threaded end of the adaptor, and contacting the inclined surface of the outer surface of the inclined point with the inclined surface of the adaptor.
摘要翻译：一个箭头和制作方法。箭头具有中空的箭头轴，具有一端具有外径的单件适配器和具有内表面的圆柱形孔，该内表面可围绕轴的第一端粘合地接合，并具有外螺纹的相对端。倾斜表面围绕外螺纹端并从一端的外径朝向孔向内逐渐变细。倾斜表面的直径大于外螺纹的直径。外螺纹和倾斜表面接收并保持具有内螺纹和倾斜表面的箭头点，使得冲击力不会传递到轴的内表面。平衡销具有容纳在箭头轴中的轴部分和与平衡销轴部分的一端互连的头部。头部具有大于轴部外径的直径，并且小于圆柱形孔的内径。该方法包括以下步骤：提供端部适配器和平衡销，将平衡销轴部分插入轴开口中，直到平衡销头部分抵靠箭头轴，将适配器孔的内表面的一部分与轴的外表面，在适配器的外螺纹端部上带有倾斜表面的箭头点，并将倾斜点的外表面的倾斜表面与适配器的倾斜表面接触。

摘要： An arrow end adaptor and a balance pin for an arrow and a method for making the same. The arrow comprising a ferrule having a large enough inner diameter to be placed over the arrow shaft, and further having an exterior threaded end whose diameter is smaller than the diameter of the arrow shaft. The point cap is designed such that an arrow point having interior threads may be attached to the exterior threaded end of the point cap. The balance pin is designed to have a head at one end that may be affixed to either a target point or a point cap and a shaft end that may be inserted into the arrow shaft.

摘要： Disclosed is a rail-type fence using electricity which includes a plurality of support posts between which are extended continuous electrical wires. The electrical wire is enclosed within and supports a conductive tubular rail. The wire is held against the inner wall of the tubular rail by end plugs and splices. An alternate embodiment of the rail-type fence includes a plurality of electrified wires positioned within the outer surface of the walls of a nonconductive tubular rail. In this embodiment, a conductive end plug transfers electricity from the electrical wire within the tubular rail to the electrified wires embedded in the rail's walls.
