摘要:
A bushing is provided for a wire. The bushing includes a polymeric body that extends a length from an end to an opposite end. The body includes a pre-coiled shape wherein the body includes at least one coil defined between the ends. The body is biased to the pre-coiled shape and is flexible such that the body is configured to be at least partially unwound from the pre-coiled shape, against the bias, for wrapping the body around the wire. The body is resiliently unwindable from the pre-coiled shape such that the body is configured to at least partially return to the pre-coiled shape as the body is wrapped around the wire.

A connector system includes a plurality of conductor piercing units supported by a frame for vertical displacement between upper disconnected and lower connected positions relative to a plurality of parallel spaced insulated conductors supported in a horizontal plane by a base plate. The piercing units are displaced between said upper and lower positions by operating disks eccentrically mounted for rotation on a horizontal support shaft that extends between an opposed pair of side walls of the frame. The base plate, frame and piercing unit assembly are arranged in an open-topped support housing that is closed by a cover member or lid. Electrical components may by mounted on the lid for connection with the piercing unit assembly.

A connector arrangement for tapping off current from a plurality of insulated input conductors includes a rectangular base member having a horizontal planar upper surface provided with a plurality of parallel seats receiving the insulated conductors, a frame mounted on the base member for supporting a plurality of terminal blocks for vertical displacement over the seats, each terminal block including an insulation piercing contact extending downwardly therefrom, and an eccentric disk arrangement for displacing each terminal block relative to the frame member between an elevated position spaced above the associated conductor seat and a lowered position in which the contact penetrates the insulation layer and engages the conductor, thereby to transmit current to an output conductor via the insulation-piercing conductor, a bus bar, and a tap-off terminal.

A blower burner is provided for a boiler heated with fluid fuels with a blower casing, which incorporates on one side the blower with the attached drive motor and where the fire tube of the burner comes out on the other side. The motor and the fire tube form protruding parts on opposite sides of the blower housing. The rear side of the fire tube protrudes beyond the side of the casing disposed toward the drive motor and the rear side of the fire tube protrudes into a cover extension attachment of the blower casing. The burner is provided with a pressure controller, where the air pressure inside of the fire tube element is measured by the input sensor signal and where the blower speed is the variable controlled by the pressure controller. Furthermore, a sound absorbing means is provided for the blower burner.
