W hat a fitting comparison with BIRCH RESISTANCES, Arms of the Ohm's Law. Backed by many years of practical experience in which their reliability has been tested under all conditions, BIRCH RESISTANCES, in their various applications, stand up to their job and can always be depended upon to provide specified service because of their first-class workmanship. Please call upon us to help you solve any Resis t a n c e Resistances ^ ****** May we quote you for of •ny of the following :— DIMMERS — REGU LA TO RS (Field, Shunt, Voltage) — RESISTANCES (Arc Lamp, Chargin», Regulating, Sliding) — RHEOSTATS — ELEM EN TS and SPIRALS. ___________________________ ASBESTOS WOVEN RESISTANCE NETS AND GRIDS H.

To-day — all the world “ rides on air’’ thanks to Mr. Dunlop’s pioneer idea. * * * More recently, Heatrae decided—after lengthy ex periment—that Monel was the ideal metal for Electric Water Heater Construc tion.

We realised, in advance, that our products would, of necessity, receive the harshest possible treatment and, that they must not fail. BRyanising survived all tests. War with its exacting demands has proved beyond all doubt that BRyanising does satisfy the claims made for it. BRyanising means better Galvanizing, for it provides the strongest possible resistance to corrosion.

Because it is Extensible it çan be driven, in 4 ft. lengths, to great depths to take advantage of deep strata of low resistivity — inaccessible economically by other means. When sunk below ground level and fitted with an “ Easy-Access ” Inspection Cover, the bonding and conductor are protected from mechanical damage and undesirable sur face potential gradients are minimised.
