STEAM ACCUMULATION.
The call for efficiency in industrial production is causing increasing attention to be given to the methods of economizing power supply, among which steam accumulation has been developed very much in the last few years. By this principle, as carried out in the " Kiesselbach " system, a varying demand for power from steam boilers can be met by a constant rate of firing, thereby enabling boilers to he fired at the most economical rate, and also a constant boiler pressure is maintained. The British and American patent rights of the system are held by Kiesselbach Steam Accuinulators, Ltd., which has an issued capital of £168,000 divided into 158,000 " A" Ordinary shares of £1 each, and 10,000 B " Ordinary shares of £1 each. Permission has been granted to deal in the " A " Ordinary shares in the Stock Exchange. The " A " Ordinary shares are entitled to 90 per cent. of the net profits, and the B " shares to the remaining 10 per cent. Manufacture has hitherto been confined to Germany, where a number of plants have been in successful operation for some time.
