What is wanted is sufficiently good workmanship to prevent contact ever being made between the distributing mains and the service wires, and this there should be no difficulty in obtaining.
Both these causes may be expected to decrease rapidly in the future, particularly if the municipalities insist on the mains being placed underground, instead of being strung on poles in the streets.
These pipes were of two classes: trunk mains and service mains.
There were no large water mains to be cared for, in fact, those in the streets were too small for ample fire protection, being only 6 in.
No changes were necessary in the mains in the avenues, but, before approving the rearrangement for the streets, the Department of Water Supply, Gas and Electricity added a 48-in.
Fortunately, there were but two trunk mains in the three streets, one a 20-in.
The service mains in 32d Street were no longer required, and were taken up and not replaced.
When a shaft leading down to the electric light mains is opened, one of those canvas shelters is put over the top.
Gas and electric light mains in this street are all led along a special conduit reached by manholes every eighty yards," said Champion.
And then he added, sharply-- "And do ye think I would let Denny-mains pass into the hands of a fool?
But our good friend of Denny-mains was far too deeply shocked and astounded to reply.
The Laird had no immediate relative to inherit Denny-mains and his very substantial fortune.
It was a merry enough dinner-party: perhaps it was the consciousness that the White Dove was still bowling along that brightened up our spirits, and made the Laird of Denny-mains more particularly loquacious.
But at dinner the Laird got on very well with our new guest; for the latter listened most respectfully when Denny-mains was demonstrating the exceeding purity, and strength, and fitness of the speech used in the south of Scotland.
The innocent eyes express such profound interest that the Laird of Denny-mains almost forgets about the coming steamer, so anxious is he to crush us with a display of his erudition.
When I left Denny-mains I told my brother Commissioners that what I could do when I was away to further the business of the Burgh I would do; and I have entered most minutely into several matters of great importance.
Denny-mains is having his whisky and hot water brought in?
It was now abundantly clear to us that Denny-mains could no longer suspect of anything heterodox and destructive this young man who was sound on drainage, pure air, and a constant supply of water to the tanks.
But I hope to see Denny-mains for myself, sir," said she, with some surprise.
There is not a square yard of Denny-mains with a farthing of mortgage on it.
Had the earthquake spared the mains they would merely have been spectacular.
The method of connecting ordinary distributing transformers to constant pressure mainsis shown by the elementary diagram, fig.
If the mains leading to a direct current motor be reversed, the direction or rotation remains the same, because the currents through both the field magnets and armature are reversed.
When the load on the secondary is reduced, for example by turning off lamps, the power taken from the supplymains by the primary coil is automatically reduced in proportion to the decrease in the load.
In addition to this, there is a magnetizing coil along the same axis, which is connected across the mains and so produces the same flux as the primary coil in a shunt induction machine.
The voltage between the mains should be used in calculating the size of wires, and the size of the neutral wire should be made in proportion to each of the main conductors that the lighting load is to the total load.
The magnetizing current of a transformer is sometimes spoken of as that current which the primary winding takes from the mains when working at normal pressure.
When the load on a transformer is increased, the primary of the transformer automatically takes additional current and power from the supply mains in direct proportion to the load on the secondary.
The plant and equipment used to purify water for drinking and other purposes, and to supply it to the mains of a town.
Neurotic as a class include all those poisons whosemains action is upon the brain and spinal cord.
A discharge pipe with a valve and spout at which water may be drawn from the mains of waterworks; a water plug.
The Horses mains to be plaited this evening, the men are to have their hair firmly pasted well plaited at the Review and to be tyed with a ribbon the end of which is to hang down.
The Horse Mains and Tails are to be Clean Washed & their Mains Plaited, which if opened out are to be again Plaited up till the Morning of the Revieu.
By means of compound motors the starting at a distance with only two mains may be effected, just as in the case of the series motor.
