Meter Presentation.

Bearings are presented at the site; at the control, and on small repeaters, on 2" meters.

The use of meter presentation considerably reduces both initial and maintenance costs for the life of a meter is almost unlimited; a meter also eliminates intricate time-base circuits which are a cathode-ray necessary part ed presentation equipment.

Another outstanding feature of this Marconi equipment is that it is the smallest VHF D/F equip nent yet produced which incor-- porates all the foregoing features. Bolk, the site and the

Automatic Steam Generator Now Marked For Export

A

new steam-generating unit which operates automatically with light oil, heavy oil gas, has been developed by Orr & Sembower, Inc., Reading, Pa., U.S.A. and is now being made available to the export trade.

sote

Known as the "Powermaster," this steam generator is complete in itself and is entirely factory- finished. Boiler, automatic burner, conden- return system, control panel, and, all accessories are shipped as a single unit. Units .can be ordered for burning light all, heavy

oil or gas, or any combination of these three. fuels.

The operation of the Power- master boller offers the following advantages to the user:
