1909 The Physical Society's Exhibition of Scientific Apparatus: 'Messrs. Everett, Edgcumbe, and Co., Limited, of 87, Victoria-street, S.W., showed, in addition to their well-known dynamometers, voltmeters, &c., a portable direct-reading potentiometer, a rotary synchroniser without sliding contacts, in which only the pivoted armature rotates, and a new photometer bench, a 10-ft. metal bench, provided with Everett-Edgcumbe direct-reading screen photometer-head to be used either as a flicker or as a comparison photometer. Their resonance frequency indicator has a range from 300 up to 400 cycles per second, and the reeds are set in a circle. The accelerometer which Mr. A. P. Trotter devised in 1904 resembles a glass-tube water-level enclosing an air-bubble; the tube is of a peculiar curvature, and marked with two scales, for rest or steady motion (when the gradient is indicated), and for acceleration.'[2]
1910 Exhibited at the Physical Society's Exhibition - the Trotter portable photometer, a trolley standard leakage detector for use by tramways, an accelerometer, a rotary synchroniser for paralleling of alternators[3]
