How it Works Dealing in simple language with steam, electricity, light, heat, sound, hydraulics, optics, etc., and with their applications to apparatus in common use The weight of that horse was supported by an armature of iron, and upon it was the statue of the Emperor, armed in the ancient fashion, with a sword in his hand. Lives of the most Eminent Painters Sculptors and Architects Vol. 06 (of 10) Fra Giocondo to Niccolo Soggi The line apparatus comprises one relay, having a single winding, and two pairs of contacts operated by its armature. Cyclopedia of Telephony and Telegraphy, Vol. 2 A General Reference Work on Telephony, etc. etc. Some cutouts have a spiral spring attached to the cutout armature. The Automobile Storage Battery Its Care And Repair There are three contact-rings a b e and three brushes c d f, which connect the armature circuits with the external circuit. The inventions, researches and writings of Nikola Tesla With special reference to his work in polyphase currents and high potential lighting 2012-03-28T02:00:22.660Z Holmes continuous current dynamo: A, armature; C, commutator; M, field magnets. How it Works Dealing in simple language with steam, electricity, light, heat, sound, hydraulics, optics, etc., and with their applications to apparatus in common use With it are furnished three nickel-plated connecting-straps, which are to be used for connecting the field and armature in "series" or "shunt." How Two Boys Made Their Own Electrical Apparatus Containing Complete Directions for Making All Kinds of Simple Apparatus for the Study of Elementary Electricity In addition to this the charging machines should be in duplicate, so that a burnt-out armature or other damage to one of the charging units will not disable the plant. Cyclopedia of Telephony and Telegraphy, Vol. 2 A General Reference Work on Telephony, etc. etc. This may be remedied by increasing the spring tension of the cutout, or removing any trouble which causes the cutout armature to bind. The Automobile Storage Battery Its Care And Repair The armature also exhibits two poles at right angles to the coils F F, like poles to those in the pole-pieces being on the same side of the coils. The inventions, researches and writings of Nikola Tesla With special reference to his work in polyphase currents and high potential lighting 2012-03-28T02:00:22.660Z The armature coils cut this and pass a current through the circuit. How it Works Dealing in simple language with steam, electricity, light, heat, sound, hydraulics, optics, etc., and with their applications to apparatus in common use These should be placed very near the back, A, so that the armature will be over them. How Two Boys Made Their Own Electrical Apparatus Containing Complete Directions for Making All Kinds of Simple Apparatus for the Study of Elementary Electricity This gives the rotary relay armature one impulse and this in turn closes the circuit of the private magnet once. Cyclopedia of Telephony and Telegraphy, Vol. 2 A General Reference Work on Telephony, etc. etc. The remedy for this trouble is to keep the mica under-cut, and to be very careful to center the armature in the lathe when taking a cut from the armature. The Automobile Storage Battery Its Care And Repair This effect is continued by the reversal of current, the polarities of field and armature being simply reversed. The inventions, researches and writings of Nikola Tesla With special reference to his work in polyphase currents and high potential lighting 2012-03-28T02:00:22.660Z The armature, as the revolving coil is called, is mounted between the poles of a magnet, where the lines of force are thickest. How it Works Dealing in simple language with steam, electricity, light, heat, sound, hydraulics, optics, etc., and with their applications to apparatus in common use If you have the right spring to the part F, of the armature, you will have no trouble. How Two Boys Made Their Own Electrical Apparatus Containing Complete Directions for Making All Kinds of Simple Apparatus for the Study of Elementary Electricity The single movement of the private magnet armature allows the escapement finger on the arm 5 to move one step and this brings the side switch contacts into the second position. Cyclopedia of Telephony and Telegraphy, Vol. 2 A General Reference Work on Telephony, etc. etc. On most cutouts there is a stop which the cutout armature strikes when the cutout opens. The Automobile Storage Battery Its Care And Repair The armature core is shown as thus wound. The inventions, researches and writings of Nikola Tesla With special reference to his work in polyphase currents and high potential lighting 2012-03-28T02:00:22.660Z A magnet, whirled outside the bell-glass, draws round the iron armature on the pivoted table, and consequently revolves the record, on the surface of which a very thin coating of gold is deposited. How it Works Dealing in simple language with steam, electricity, light, heat, sound, hydraulics, optics, etc., and with their applications to apparatus in common use The armature is fastened to F by a screw, S. A copper bur is put under the head of S to aid in keeping A from rocking sidewise. How Two Boys Made Their Own Electrical Apparatus Containing Complete Directions for Making All Kinds of Simple Apparatus for the Study of Elementary Electricity The private magnet armature will, therefore, be operated by the finger of the rotary magnet armature on the first rotary step. Cyclopedia of Telephony and Telegraphy, Vol. 2 A General Reference Work on Telephony, etc. etc. Shift the brushes until the armature does not tend to rotate in either direction. The Automobile Storage Battery Its Care And Repair This may be done by constructing a motor with two independent sets of fields, and with either one or two armatures electrically connected, or by using two armatures and one field. The inventions, researches and writings of Nikola Tesla With special reference to his work in polyphase currents and high potential lighting 2012-03-28T02:00:22.660Z Nothing, however, so impresses the observer as the formidable character of the offensive weapons with which they were furnished, and the amazing strength of their defensive armature. The Testimony of the Rocks or, Geology in Its Bearings on the Two Theologies, Natural and Revealed It has four binding-posts,—making it possible to energize the field or armature separately,—and so it can be used in circuits with reversers and rheostats for experiments.
