See These Latest I GRANIC Devices AT STAND No. 7 (Radio and Electrical Exhibition) IGRANIC L.F. TRANSFORMER TYPE "J" The Igranic L.F. Transformer 'type 'T has been developed to meet the it 10 demand for a Low Frequency Transformer which, while being of small dimensions and comparatively light in weight, will give amplification of a standard comparing favourably with heavier and more expensive types of instruments at present on the market. The Igranic L.F. Transformer Type -.E meets all these requirements admirably.Itis a remarkably efficient instrument, measuring only 3I -Bin. long by I 7.8in. wide by 2in. high, and weighing approximately 10o.s. Its light weight and small dimensions constitute features which render the instrument particularly suitable for incorporation in portable receivers. We can assert with confidence that the performance of this transformer is definitelybetter than any other transformer ofimilar size and price, and including many instruments sellingat considerably higher prices. Price 27/6 Supplied in 2 ratios of 3.1 and 6.1. IGRANIC SCREENED CONDENSER The Igranic Screened Condenser will be found suitable for use in all circuits employing reaction on the Reinert. principle. Itisof the straight-line capacity type, and is provided with spindle of insulating material, which. in conjunction with the screening case, enables the condenser to be used in any position without experiencing trouble due to hand capacity effects. The metal screening case also acts as an effective electrostatic screen, which is of particular importance in neutralised and short wave circuits.The vanes are of stout sheet brass, maintained rigidly in position by the same method of assembly which isa feature of the Igranic "Lokvane** Condenser. Maximum capacity is .00015 mfd. Price 14/3 IGRANIC VERNIER DRUM CONTROL Here is the very latest aid to rapid tuning -in.Just a few quick turns of the Drum Control, a slight adjustment, and you bring in the transmission at full strength. The Vernier Drum Control comprises a largediametermoulded drivingdisc. serrated for "thumb" control in coarse tuning -in and so arranged as to engage with a worm drive, which may be thrown into mesh for the purpose of providing fine Vernier Control by means of a small control knob. This makes it possible to make rapid search for any desired station. The main driving disc carries two sectors of white ivorine, one engraved with indicating scale, and the other plain, on which may be pencilled records of stations received. The sectors are translucent and a small electric lamp mounted on the bracket illuminates the scale readings-a great aid to making accurate tuning adjustments at any time. Current for this lamp may be derived from the L.T.Battery, and a separate switch may be provided to allow for switching off the lamp when not required. A beautiful escutcheon plate moulded in best quality Bake- lite imparts to the receivers a most artistic appearance, worthy of the best surroundings. 37/6 These Igranic devices aretobe seen atthe Radio and ElectricalExhibition, Sydney Town Hall, where every information will be gladly given at STAND No. 7 NOYES BROS.

..... , - "CLIMAX" The Battery Scientifically Produced by a New and Better Process ! S CIENTIFIC research has revealed the important fact that acids and Sal - ammoniac (largely used in ordinary High Tension Radio Batteries) de- compose the Zinc Electrodes, causing moat of the battery trouble the user has to contend with. The "Climax" formula does not include either of these chemicals. "Climax" is made by an entirely new method, which ensures perfect operation over every period of a long and usefullife. Noise and unsteady operation need never be reckoned with if your set is "Climax" equipped! Undoubtedly, the "Climax" in battery making has been reached in this new -process -product, so aptly named. CLIMAX "B" BATTERIES 30 Volts, 8/-; 45 Volts, 12/-; 60 Volts, 16/-; 90 Volts, 24/-. CLIMAX "C" BATTERIES 9 Volts, 4/.; 15 Volts, 6/.. Equip Your Set with "Climax" To -day and get Maximum Results!

CLIMAX BATTERIES FOR YOUR TORCH The next time you order torch batteries, a ee they are "CLIMAX." You will be re- warded with a steadier, brighter, and never -failing light, plus longer life and service, than you have ever had before.
