The coils of the electromagnets are differentially wound with silk-covered wire, 4 mils (= 004 inch) in diameter, to a total resistance of 400 ohms. This differential winding enables the instrument to be used for " duplex " working, but the connexions of the wires to the terminal screws are such that the relay can be used for ordinary single working.
In the ordinary methods, a differentially wound receiving instrument was used, one coil being connected with the cable Company and the various Atlantic cables, are worked duplex on method of duplexing a cable was described by Lord Muirhead's plan.
This arrangement can be duplexed in the way already explained, by providing differential relays and arranging for the outgoing currents to divide differentially through the two relays at each end.
Since 1890 further and more rigorous application of the telegraphic method of determining longitudes differentially with Greenwich has resulted in a slight correction (amounting to about 2" of arc) to the previous determination by the same method through Suez.
In any case it is clear that we have in these muscles an apparatus'for causing the blood to flow differentially in increased volume into either the pericardium, through the veins leading from the respiratory organs, or from the body generally into the great sinuses which bring the blood to the respiratory organs.
Nothing further was done in Natal up to the establishment of the Union of South Africa, when all questions specially or differentially affecting Asiatics were withdrawn from the competence of the provincial authorities.
The establishment of the Union of South Africa removed from the competence of the Transvaal provincial council all legislation specially or differentially affecting Asiatics.
The certainty with which tissues can now be fixed in the state they were in when living, and the delicacy with which they can be stained differentially, have been the means of opening up a new world of exploration.
The blood of most species behaves differentially towards precipitants, and it is therefore conceivable that when blood is used as food and is elaborated into special compounds for the nutrition of the reproductive organs of a parasite, these specific or larger differences in the blood of animal hosts may prevent the ripening of the gonads of a widely diffused parasite and only one particular kind of blood prove suitable.
The control and administration of native affairs (which before the Union was, except at the Cape, largely in the hands of the colonial governors personally) is vested exclusively in the governor in council and to the same authority is entrusted all matters specially or differentially affecting Asiatics throughout the Union.
The imperial government made but one alteration of consequence - that explicitly placing the control and administration of matters " specially or differentially affecting Asiatics "in the sole control of the union parliament.
24), instead of sending the currents through the two coils of a differentially wound relay or receiving a and b are inserted, and the receiving instrument is.
The longitude of the Tashkent observatory has been determined by telegraph differentially with Pulkova as follows: H.
