Abstract: A powered pump unit is adapted to operate with a vacuum cup device having a pump cylinder for a manually operated vacuum pump. The powered pump unit includes a pump unit housing, a power source receiver, a vacuum pump, a pump drive, and a sealing arrangement. The pump unit housing is adapted to be received in the pump cylinder in an operating position after the piston is removed from the pump cylinder. The power source receiver, vacuum pump, and pump drive are each mounted on the pump unit housing and at least one of them is at least partially located in the pump cylinder when the pump unit housing is in the operating position. The pump drive is operatively connected to drive the vacuum pump to produce a vacuum that is applied to the vacuum cup of the vacuum cup device.

Abstract: A cutting wire placement tool includes an elongated tool body, a pulling element carrier structure, and an elongated pulling element. The elongated tool body has a handle end and a sealant piercing end opposite the handle end, and the pulling element carrier structure is located at the sealant piercing end of the elongated tool body. The pulling element carrier structure includes a recess and at least one piercing element having a configuration to pierce a sealant material as a sealant piercing force is applied to the elongated tool body. The elongated pulling element is connected to the elongated tool body at a location spaced apart from the sealant piercing end of the elongated tool body and has a pulling loop which is adapted to be movable between an insertion position and a pulling position relative to the recess of the pulling element carrier structure.
