Title: Cooling tower with tubular heat exchanger - has conically shaped ionising electrodes to improve heat transfer
Inventor: RIEGER ALOIS DIPL ING
IPC: F28F13/16
Filed: 1973-10-02
Abstract: Air flow is induced through a vertical tapered cooling tower. The water to be cooled passes through tubes arranged at the base of the tower so that the induced air stream flows over them. The avoidance of direct contact between air and water prevents evaporative loss of water. Electrodes are placed upstream of the air flow over rows of tubes and are supplied with high tension from a source. They produce an ionised layer of air on the surface of the tubes which improves heat transfer. The ionisation and heat transfer is further improved by the conical shape of the electrodes, with the tip of the cone facing the tubes downstream of the electrodes.

Title: Automatic winding and clamping of dynamo windings - with winding machine with an automated tool for leading the windings through the correct commutator clamp slots
Inventor: WILDING GERARD EDWARD
IPC: H02K15/09
Filed: 1974-04-18
Abstract: The device is for winding and clamping dynamo armature windings automatically and guiding them tightly through the correct commutator clamping slots. The system is more rapid and therefore cheaper than the traditional method of guiding and clamping the armature windings. The winding machine guides the two wires from spools by a complex mechanism through the armature slots. At the end of each slot each wire is guided into the appropriate commutator clamp slot, along the commutator, round the shaft of the dynamo, back along the commutator and into the next armature slot. This is achieved by a cup shaped mechanism with two longitudinal slots and shaped guides which fit over the commutator. The wire is passed through the slits in this device and guided along the correct path by separated clockwise and counter clockwise movements of the arrangement.
