    Abstract: A picture frame gasket channel and cooperating resilient picture frame gasket member where the picture frame gasket channel is welded onto the cover of an enclosure for electrical equipment. The equipment is contained within a suitable container having an edge which contacts a flat portion on the picture frame gasket member to compress the gasket against the inner surface of the channel to thus provide a fluid tight enclosure for electrical equipment.

    Abstract: An isolating switch comprising spaced, cylindrical hollow conductors capable of carrying high electrical currents mounted within gas filled, sealed concentric cylindrical enclosures. The isolating switch when opened, has a large insulating gap for withstanding high voltages. The switch includes a bridging member which retracts inside of one of the associated hollow poles or conductors when the switch is open, and extends to bridge the gap between the two cylindrical poles when the switch is closed, thus, providing a continuous electrical path from one pole or conductor to the other. The bridging member is actuated by a suitable driving mechanism or means. The means for establishing an electrically conducting path between two conductors is independent from the means for establishing a mechanical connection between said conductors. The bridging member includes electrical contacts which are of the loop type, that is generally U-shaped conductors which may be secured to a movable, electrically conducting drum to engage the inner periphery of both of the associated conductors.

    Abstract translation: 隔离开关包括间隔开的圆柱形空心导体，其能够承载安装在填充气体的密封同心圆柱形外壳内的高电流。 隔离开关打开时，绝缘间隙大，可承受高压。 开关包括桥接构件，当开关打开时，桥接构件缩回到相关联的空心极或导体之一的内部，并且当开关闭合时，桥接构件延伸以桥接两个圆柱形极之间的间隙，从而提供来自一个的连续电路 杆或导体到另一个。 桥接构件由合适的驱动机构或装置致动。 用于在两个导体之间建立导电路径的装置独立于用于在所述导体之间建立机械连接的装置。 桥接构件包括环形类型的电触头，其通常为U形导体，其可固定到可移动的导电鼓以接合两个相关导体的内周。

    Abstract: A high-voltage electric switch comprising a plurality of spaced insulator stacks having a switch blade movably supported thereon and a contact jaw supported on one of the other insulator stacks and disposed in the path of movement of the switch blade. The insulator stacks are mounted on a common supporting base which includes a pair of generally parallel channel members and a pair of reinforcing members disposed between said channel members and spaced from the ends of said channel members.
