Abstract: The fire prevention and cooling system for cables and trunks in workshops etc. consists of a channel shaped to follow the path of the cables and to collect cooling water sprayed from nozzles above the cable. The cooling water is directed onto the cables and is collected by the channel which lies beneath the cable. The channel is in the form of ducting with dam walls across it at places, where it drops down to another level. The dam walls have holes at the bottom to allow water to flow from a higher to a lower level. The side walls of the ducting have overflow holes towards their top edges. The system can be adapted to vertical cables and to stacked horizontal cables.

Abstract: Electrochemical cell has impervious electrode plates mounted in a symmetrical circular fashion forming a closely packed bundle of plates close to or on top of one another. These are spaced by spacers which form an electrolyte space between them, the spacing being 10 mm. The plates are arranged around a hollow rotatable shaft, the hollow space being connected to the electrolyte space and, being attached rigidly to the shaft, rotate with it when it rotates. The bundle can rotate as a whole, or all but the outer now of plates can rotate. Alternatively the plates can alternately rotate and stop. The electrical efficiency is much improved by close packing of the plates. However it can lead to high local current densities with consequent local corrosion of the plates. The centrifugal bundle gives the advantage of close packing but avoids the local corrosion.
