With over 100 colour photographs, "Folk Furniture of Canada's Doukhobors, Hutterites, Mennonites and Ukrainians "offers a stunning visual record of the culture and values of these four ethno-cultural groups.

Excerpt from Electrical Laboratory Notes and FormsAt every point. In the neighbourhood of a magnet or conductor carrying a current there is a magnetic force, and the region within which this force manifests itself is called a magnetic field. At each point in a magnetic field the magnetic force has a certain direction and magnitude. F a. Very long magnetic needle is held with one pole at any point in a magnetic field and the other pole removed ...

Excerpt from Hertzian Wave Wireless TelegraphyWe shall, in the first place, consider the transmitting arrangements and, incidentally, the nature of the effect or wave transmitted, in the second place, the receiving appliances, and, finally, discuss the problem of the isolation or secrecy of the intelligence conveyed between any two places.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from An Elementary Manual of Radiotelegraphy and Radiotelephony: For Students and Operators It is assumed, however, that any user of this Manual has a general acquaintance with the elementary facts of electrical science. It has not been considered necessary to encumber the pages with many references to original papers or patent specifications. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic b...

Excerpt from A Handbook for the Electrical Laboratory and Testing Room, Vol. 1 The only excuse that can be offered for adding another book to the already full catalogue of Electrical literature, especially under the heading of Electrical Measurements, is that, in spite of the numerous excellent works on this subject, there seemed room for one dealing more particularly with the requirements of electrical engineers as distinguished from electri...

Excerpt from Magnets and Electric Currents, an Elementary Treatise for the Use of Electrical Artisans and Science TeachersLet the idea now conveyed by the term magneto motive force be expressed, as Mr. Heaviside and other writers have already done, by the word gaussage (pro nounce and let the gaussage between any two points or around any magnetic Circuits be measured in a unit termed a gauss, such that 80 ampere-turns are equal to one microgau...

Excerpt from The Principles of Electric Wave Telegraph During the last few years the Author has been honoured on several occasions with the request to deliver Courses of Cantor Lectures at the Society of Arts, London, in connection with this subject, and the present treatise is based to a large extent upon the subject-matter of the lectures so delivered, bearing the titles.

Excerpt from The Wireless Telegraphist's Pocket Book of Notes, Formulae, and Calculations For information on the purely engineering side of radio-telegraphy connected with boilers, engines, steam piping, foundations, and building work, the existing engineering pocket books provide, but there seemed to be an opening for a small reference book of radiotelegraphic formulæ which the author has endeavoured to fill. About the Publisher Forgotten ...

Excerpt from Electric Lamps and Electric Lighting: A Course Delivered at Lectures on Electric Illumination Delivered at the Royal Institution of Great Britain The following pages are a transcript, with some additions, of a course of Four Lectures on "Electric Illumination, " delivered by the Author to afternoon audiences at the Royal Institution, London. They are, however, in no sense presented as an adequate treatment of a subject which has ...

Excerpt from The Alternate Current Transformer, Vol. 1 Copenhagen famous as the birthplace of the discovery that an electric current passing through a metallic wire magnetises it circularly and creates round it a magnetic field, the direction of the lines of magnetic force being closed curves surrounding the axis of the wire. Faraday placed these two phenomena side by side before his mental vision, and he asked himself whether it was possible...
