Fidelity Title Trust Company v. Dubois Electric Company/Opinion of the Court > 자유게시판

Flags were flying from the little church and the telegraph station on shore. The wire glides so easily to the bottom that 'flying soundings' can be taken while the ship is going at full speed. But even this is sometimes difficult since pulling big sized buckets full of water from the great depth of the well is also a problematic and effort-giving task. It was too late to try again that year, but the following summer the Agamemnon and Niagara, after an experimental trip to the Bay of Biscay, sailed from Plymouth on June 10 with a full supply of cable, better gear than before, and a riper experience of the work. When we consider that every word is, on the average, composed of fifteen separate waves, we may better appreciate the rapidity with which the siphon can move. The Meyer-Baudot and the Quadruple receive four messages at once and record them separately; while the harmonic telegraph of Elisha Gray can receive as many as eight simultaneously, by means of notes excited by the current in eight separate tuning forks. At 9 a.m. a message from England cited these words from a leading article in the current Times: 'It is a great work, a glory to our age and nation, and the men who have achieved it deserve to be honoured among the benefactors of their race.' 'Treaty of peace signed between Prussia and Austria.' The shore end was landed during the day by the Medway; and Captain Anderson, with the officers of the telegraph fleet, went in a body to the church to return thanks for the success of the expedition.

In the Morse code the letters of the alphabet are represented by combinations of two distinct elementary signals, technically called 'dots' and 'dashes,' from the fact that the Morse recorder actually marks the message in long and short lines, or dots and dashes. Ribbon cable - Useful when many wires are required. Coaxial Cable:- It is also called coax cable. However, stranded or braided wires offer superior flexibility and more resistance to fatigue cracking over time.Wires are manufactured in specific diameters, called gauges. The needle is thus prevented from idly swinging about at each deflection, and the separate signals are rendered abrupt and 'dead beat,' as it is called. Generally, electrical cables & wires are considered as same but they are somewhat different. It follows, that with a receiving instrument set to indicate a particular strength of current, the rate of signalling would be very slow on long cables compared to land lines; and that a different form of instrument is required for cable work. This is owing to the phenomenon of induction, very important in submarine cables, but almost entirely absent in land lines. In submarine cables, as is well known, the copper wire which conveys the current is insulated from the sea-water by an envelope, usually of gutta-percha.

Longer distances are theoretically conceivable, but they may introduce additional issues, making copper an unreliable transmission medium over longer distances. Foot soldiers in our modern Army now are "walking computers." Night visiongoggles, GPS receivers, computers and radios are becoming commonplace. Another very modern design is a Kundalini lamp which is a very slim plexiglass tube in a choice of four colours and providing both a reading light and ambient light that can be dimmed. The cable core contains a single solid or stranded central strength element that is surrounded by optical fibres; these are either arranged loosely in a rigid core tube or packed tightly into a cushioned, flexible outer jacket. In the siphon recorder script dots and dashes are represented by curves of opposite flexure. The recorder was first used experimentally at St. Pierre, on the French Atlantic cable, in 1869. This was numbered 0, as we were told by Mr. White of Glasgow, the maker, whose skill has contributed not a little to the success of the recorder. The air in the little chamber surrounding the mirror is compressed at will, so as to act like a cushion, and 'deaden' the movements of the mirror. This unique and interesting little motor owes its somewhat epigrammatic title to the resemblance of the drum to one of those sparred wheels turned by white mice, and to the amusing fact of its capacity for performing work having been originally computed in terms of a 'mouse-power.' The mill is turned by a stream of electricity flowing from the battery above described, and is, in fact, an electro-magnetic engine worked by the current.

The practical advantage of this extreme delicacy is, that the signal waves of the current may follow each other so closely as almost entirely to coalesce, leaving only a very slight rise and fall of their crests, like ripples on the surface of a flowing stream, and yet the light spot will respond to each. The merit of this receiving instrument is, that it indicates with extreme sensibility all the variations of the current in the cable, so that, instead of having to wait until each signal wave sent into the cable has travelled to the receiving end before sending another, a series of waves may be sent after each other in rapid succession. Instead of using kerosene, diesel or propane, the Heat Wave heater offers the convenience of clean electric heat on the job site. Electric devices that use heating elements, like a hair dryer or curling iron, require a converter. It protects electrical appliances and electronics from dangerously high levels of electric current. They require a certain definite strength of current to work them, whatever it may be, and in general it is very considerable. Bright died suddenly of heart disease on 3 May 1888, at his brother's residence at Abbey Wood, Kent, and was buried in Chiswick churchyard.
