Abstract: A current collector wire (1) is over-moulded with a seal (2) made from a thermoplastic elastomer (Santoprene 64) having a (64) Shore A hardness rating. In a three electrode carbon monoxide sensor three current collector wire (1a, 1b, 1c) and seal (2a, 2b, 2c) combinations are inserted into the body (3) through receiving apertures (12a, 12b, 12c) in a side wall of the body, so that the current collectors protrude through connection apertures (12a, 12b and 12c). The outside diameters of the seals and the bores of the apertures are dimensioned to provide an interference fit of the one in the other. The seals are pressed home into receiving apertures in the body (3) to provide compression of the seals against both current collectors and the aperture bores resultant from the interference. Gold-plated phosphor bronze clips (8) are attached which locate on and are retained by barbs on the housing, thereby trapping the current collector wires and providing electrical contact to external circuitry.

Abstract: Apparatus for attaching a disk to a spindle of a spinstand includes a spindle having a fluid pressure port therethrough for delivery of fluid pressure. A spindle adapter is adapted to be attached to the spindle and for holding a disk. The spindle adapter has a piston movable therein to clamp a disk between the piston and an opposing surface in response to fluid pressure applied through the spindle fluid pressure port. A disk can be attached to the spindle by offering the disk up to the spindle adapter, and applying fluid pressure to the spindle fluid pressure port to cause the piston to clamp the disk against the opposing surface. The disk can then be spun up on the spindle.

Abstract: Apparatus for loading a read/write head to a spinstand has a load area for receiving at least one head to be tested. The apparatus further has a first station having a coarse precisor arranged to provide a coarse positioning of the head. A first automation device is arranged to pick a head from the load area and to deliver it to the coarse precisor. The apparatus has a deck having a test station at which a head can be tested.
