German scientists Eilhard Wiedemann, Heinrich Hertz and Goldstein believed they were " aether waves ", some new form of electromagnetic radiation, and were separate from what carried the electric current through the tube.

In an RCA ( Radio Corporation of America ) advertisement in Popular Science Magazine describing a new " memory " vacuum tube it had developed, RCA stated:

In 1907, Ernest Rutherford and Thomas Royds demonstrated that alpha particles are helium nuclei by allowing the particles to penetrate the thin glass wall of an evacuated tube, then creating a discharge in the tube to study the spectra of the new gas inside.

The inauguration of the new Holborn Station on 10 October 1865 was marked by having the Duke of Buckingham, the chairman, and some of the directors of the company blown through the tube to Euston ( a five minute trip ).

Congreve prepared a new propellant mixture, and developed a rocket motor with a strong iron tube with conical nose.

In about the middle of the 2nd millennium BC a new category of decorative tube was introduced which imitated a line of granules.

Lieutenant-Colonel Boxer adapted his design in 1864 to produce shrapnel shells for the new rifled muzzle-loader ( RML ) guns: the walls were of thick cast iron, but the gunpowder charge was now in the shell base with a tube running through the centre of the shell to convey the ignition flash from the time fuze in the nose to the gunpowder charge in the base.

The caseless rounds needed air vents to clear the gun tube and breech prior to loading another round, while the M48 breech block opened as the used shell was ejected and closed as the new shell was shoved in.

The missile body consisted of a long tube with fold-out fins at the extreme rear, which was propelled from the new M81 gun with a small charge strapped on the rear.

His first new design for the Germans to be produced in any numbers was the Fokker M. 5, which was little more than a copy of the Morane-Saulnier G, built with steel tube instead of wood for the fuselage, and with minor alterations to the outline of the rudder and undercarriage and a new aerofoil section.

After a conservative procedure that attempts to preserve the affected fallopian tube such as a salpingotomy, in about 15-20 % the major portion of the ectopic growth may have been removed, but some trophoblastic tissue, perhaps deeply embedded, has escaped removal and continues to grow, generating a new rise in hCG levels.

The development of radar before and during World War II was a great stimulus to the evolution of high frequency transmitters in the UHF and microwave ranges, using new devices such as the magnetron and traveling wave tube.

It is remarkable that the demands of the Second World War did not delay new rolling stock until after the war – virtually every other tube project was either delayed or cancelled-but, having been ordered in 1938, construction would have been well advanced when war broke out.

The line was converted to four-rail operation in common with other tube lines: the original steel positive rail was retained, with the new negative rail made from aluminium.

The new car, launched in 1923 featured a rigid backbone tube with swinging semi-axles at the rear giving independent suspension.

On the other hand, according to the conservative theory, we should obtain one original DNA strand and a completely new one i. e. two fine lines in the test tube placed separately one from the other.

The disadvantage of quenching is that for a short time after a discharge pulse has occurred ( the so-called dead time, which is typically 50-100 microseconds ), the tube is rendered insensitive and is thus temporarily unable to detect the arrival of any new ionising particle.

She used a new fine focus X-ray tube and microcamera ordered by Wilkins, but which she refined, adjusted and focused carefully.

Wooden carriages were originally hauled by steam locomotives, and at the start of the 20th century the District and Metropolitan were seeing increased competition in central London from the new Underground Electric Railways of London ( UERL ) tube lines and the use of buses.

At first the Metropolitan had advocated a new underground line roughly following the line of the Edgware Road between the tube station and a point near Willesden Green.

The tube extension opened in 1926, with seven new stations, all designed by Charles Holden in a modern style.

Further progress was disrupted by the start of the war, though enough had been made to complete the electrification of the High Barnet branch onwards from East Finchley over which tube services started on 14 April 1940 ; the new ( deep-level ) Highgate station finally opened on 19 January 1941.

His advice, his voice saying his poems, the fact that he had not so much as touched her -- on the contrary, he had put his head back and she had stroked his hair -- this was all new.

and Robinson Roy, who had gone down this line ten minutes before to set a new depth record for the free dive, was already back on the surface.

School began in August, the hottest part of the year, and for the first few days Miss Langford was very lenient with the children, letting them play a lot and the new ones sort of get acquainted with one another.

Satisfied at last, and after a few amorous gambits on her part which convinced Delphine that Dandy was capable of learning new arts, she opened the window and called to her liveried driver.

So Dandy Brandon trustingly entered the house with Delphine Lalaurie and trudged up the rear steps to the attic room which was to be his new home.

It was a brilliant debut, so much so indeed that it aroused a new vitality in the younger poets, as did Byron's Childe Harold.

At first glance this appears strange: of all people, was not America founded by rugged individualists who established a new way of life still inspiring `` undeveloped '' societies abroad??

The portrait that had developed, fragmentarily but consistently, was the portrait of a man to whom serious thinking is alien enough that the making of a decision inhibits, when it does not forestall, any ability to review the decision in the light of new evidence.

His nationalism was not a new characteristic, but its self-consciousness, even its self-satisfaction, is more obvious in a book that stretches over the long reach of English history.

As always, the ranks worked out new and better tactics, but there was brilliance in the way the field commands adopted these methods and in the way the army commanders incorporated them into their military thinking.

It is difficult to say what Thompson expected would come of their relationship, which had begun so soon after his emotions had been stirred by Maggie Brien, but when Katie wrote on April 11, 1900, to tell him that she was to be married to the Rev. Godfrey Burr, the vicar of Rushall in Staffordshire, the news evidently helped to deepen his discouragement over the failure of his hopes for a new volume of verse.

The charge was so farfetched that Woodruff paid little attention to it, and answered Pike in a rather bored way, wearily declaring that a `` new hand '' was pumping the bellows of the Crittenden organ, and concluding: `` In a controversy with an adversary so utterly destitute of moral principles, even a triumph would entitle the victor to no laurels.
