Abstract: A non-contacting position sensor (20) for sensing and determining the position between two relatively-movable members (23, 31) includes a pair of flux-conductive converging polepieces (21, 22) mounted on one of the members (23); a magnetic sensor (29) mounted on the one member and positioned proximate the convergent polepiece ends, this magnetic sensor being adapted to produce an output signal as a function of the magnetic flux density therein; and a magnet (30) mounted on the other member (31) for movement toward and away from the magnetic sensor, this magnet being positioned between the polepieces to define the first air gap between the magnet and one polepiece and a second air gap between the magnet and the other polepiece, the reluctances (RV1, RV2) of the first and second air gaps (32, 33, respectively) varying as a function of the position of the magnet relative to the magnetic sensor such that the sensor output signal will be a function of the position of the magnet from the magnetic sensor.

Abstract: A method and apparatus for joining panels, which panels have bevelled trailing and leading edge faces, the apparatus and method abut the trailing and leading edge faces of adjacent panels and secure them together by means of an adhesive and the application of a force to the scarf joint.
