CABLE INSTALLATION USING INDUCTION
First Claim
1. A device for use with a conduit having a first conduit end and a conduit second end, into which conduit a cable can be installed using a flow of air into the first conduit end, the device being suitable for confirming that the air is flowing out from the second conduit end, the device comprisinga housing,means to enable connection of the device to the second conduit end,a detector arranged to detect an electrical property change, andan actuator for causing an electrical property change detectable by the detector,wherein in use, the air flowing into the device causes the detector and the actuator to move relative to each other, causing an electrical property change detectable by the detector.

Abstract
A device for use with a conduit having a first conduit end and a conduit second end, into which conduit a cable can be installed using a flow of air into the first conduit end, the device being suitable for confirming that the air is flowing out from the second conduit end. In an embodiment, the device includes a housing, means to enable connection of the device to the second conduit end, a detector arranged to detect an electrical property change, and an actuator for causing an electrical property change detectable by the detector, wherein in use, the air flowing into the device causes the detector and the actuator to move relative to each other, causing an electrical property change detectable by the detector.

13. A device for use with a conduit having a first conduit end and a conduit second end, into which conduit a cable can be installed using a flow of air into the first conduit end, the device being suitable for confirming that the air is flowing out from the second conduit end, the device comprising
a housing, means to enable connection of the device to the second conduit end, a piston moveably located within the housing, and a detector for detecting a change in a position of the piston, wherein in use, the air flowing into the device causes a change in the position of the piston within the housing, which is detected by the detector.
