A laboratory technician writing notes of his observations at the bench of the Ultra-Violet Emission Spectrograph. The emission spectrograph is being used to determine the concentration of additive metals and wear products in lubricating oil. Only a few drops of the oil sample are required in the spectrograph equipment and the test is completed in about ten minutes. The sample is Excited by heating in an electric arc or spark. The light emitted contains a range of wavelengths which are. characteristic of the elements present. The instrument separates the light according to the wavelength and measures the intensity of those wavelengths of interest.

It Supplants The Oboe -- The British Broadcasting Corporation has devised a generator which supplants the oboe as the source of standard musical pitch for orchestra about to broadcast. The generator is shown in the photograph without its cover.The note emitted by the generator has a frequency of 440 cycles per second - the internationally agreed standard of pitch for A in the treble stave - and is rich in harmonics. Its frequency is maintained to within ± 1 part in 2000 of its nominal value. The generator consists of a valve oscillator and a loudspeaker, and is mains-operated. Being light and compact it can readily be taken from studio to studio. November 14, 1951. (Photo by BBC Photograph).
