    • In an overvoltage arrester with an enclosed spark gap assembly of electrode disks and intermediate spacers of annular shape, at least one electrode of a pair has an excentrically located projection directed towards the other electrode of the pair and thereby defines in the ring space of the annular spacer a spot of initial response. The annular spacer has a lateral opening at a peripheral locality substantially opposite the excentric projection. The opening extends from the inner periphery through the spacer to the outer periphery thereof and has a small width in the peripheral direction as compared with the total extent of the periphery.
    • 在具有环形形状的电极盘和中间间隔物的封闭火花隙组件的过电压避雷器中,一对电极的至少一个电极具有朝向该对的另一电极的偏心定位的突出部,从而限定在环形空间中的环形空间中 间隔一个初始响应点。 环形间隔件在外围位置处具有基本上与偏心突起相对的侧向开口。 开口从内周延伸通过间隔件到其外周,并且与周边的总面积相比在周向方向上具有小的宽度。

    • A torch suitable for use in recreational applications, such as with patios or decks, includes a gas cylinder, a holder for the cylinder, a pole to support the holder and a burner for producing a stable, visible flame. The burner includes one or more holes for injecting primary air near a flow-controlled gas orifice and a burn tip spaced from the orifice. A bowl is mounted about the burn tip and is preferably shaped for providing wind resistance and admitting secondary air at its exit to produce a stable, visible flame. In the preferred embodiment, the enclosure is made from plastic, and has a socket for receiving the pole. An oil, such as citronella oil, may be mixed with the propane or other gas in the cylinder to scent the area in which the torch is used.
