RADIO AND ELECTRICAL EQUIPMENT 2nd November, 1938. Dear Sir, For attention of the Chief engineer. The booklet accompanying this letter is probably the most interesting piece of engineering literature to reach you this year. It opens out new fields for production testing and is particularly applicable to your products. In the United States these Vibration Pickups are used by the leading motor car manufacturers, aeroplane engine manufacturers, machine tool, ball bearing and dynamo manufacturers, to say nothing of manufacturers of vacuum cleaners, air compressors, etc. etc. The Vibration pickups and associated apparatus, are inexpensive and easy to use. Their use enables you to solve many of your testings problems and enables you to make these tests much more quickly than with any other form of apparatus. Our engineers will be glad to assist you in designing special applications for your particular requirements. May we have the pleasure of hearing from you? Yours very truly, R.A. ROTHERMEL LIMITED, R.A. Rothermel, Director. RAR/MB | ||
