Representative of Germany's industry was the steel giant Krupp, whose first factory was built in Essen.

Steel is often cited as the first of several new areas for industrial mass-production, which are said to characterise a " Second Industrial Revolution ", beginning around 1850, although a method for mass manufacture of steel was not invented until the 1860s, when Sir Henry Bessemer invented a new furnace which could convert wrought iron into steel in large quantities.

At the center of the courtyard he designed a glass and steel pyramid, first proposed with the Kennedy Library, to serve as entrance and anteroom skylight.

In 1847 Krupp made his first cannon of cast steel.

After he became regent in 1859, Prussia bought its first 312 steel cannon from Krupp, which became the main arms manufacturer for the Prussian military.

Higher-quality armour of steel would have given considerably greater protection, which accords well with the experience of Oxford's men against the elite French vanguard at Poitiers in 1356, and des Ursin's statement that the French knights of the first ranks at Agincourt, which included some of the most important ( and thus best-equipped ) nobles, remained comparatively unhurt by the English arrows.

* 1976 – The rollercoaster Revolution, the first steel coaster with a vertical loop, opens at Six Flags Magic Mountain.

The AKM (-Automatic Kalashnikov Modernized ) first appeared in 1963, which was lighter and cheaper to manufacture due to the use of a stamped steel receiver ( in place of the AK47's milled steel receiver ), and contained detail improvements such as a re-shaped stock and muzzle compensator.

Opel also produced the first mass-production vehicle with a self-supporting all steel body.

In 1837 John Deere introduced the first steel plough ; it was so much stronger than iron designs that it was able to work the soil in areas of the US that had previously been considered unsuitable for farming.

That on the western side was erected first, in direct response to the ban on sales of Western newspapers in East Berlin, and comprised an illuminated display board 30 m wide and 1. 5 m deep, facing east, supported on three steel lattice towers 25 m high and topped by the words DIE FREIE BERLINER PRESSE MELDET ( The Free Berlin Press Announces ).

Now unsolder and disassemble the frame except for the two 12'' '' and the first two 3-3/4'' '' bars ( `` A '' and `` B '' pieces ), which are soldered together.

The transom frame is made first with the joints lapped, glued and fastened with one-inch, No. 12 Stronghold nails.

Some people even believe that this was the biblical event of Noah's flood, but despite their historical significance, the first spectacular images of these submarine channels were obtained in 1999 ( Di Iorio, et al., 1999 ) in the frame of a NATO SACLANT Undersea Research project using jointly the NATO RV Alliance, and the Turkish Navy survey ship Çubuklu.

The great majority of today's bicycles have a frame with upright seating which looks much like the first chain-driven bike.

This was the tallest building in Hong Kong and Asia from 1990 to 1992, the first building outside the United States to break the 305 m ( 1, 000 ft ) mark, and the first composite space frame high-rise building.

The first time derivative evaluated within a reference frame with a coincident origin at but rotating with the absolute angular velocity is:

The first half contains only the odd-numbered lines of a full frame.

Linnaeus was the first to frame the balance of nature as a testable hypothesis.

Next, inside this first flashback, the Lady of the title narrates another story, presented in flashback form, but with cutaways inside it back to events occurring in the time frame in which she is doing her narrating.

Hundreds of fables were composed in ancient India during the first millennium BC, often as stories within frame stories.

The actual frame in which a protein sequence is translated is defined by a start codon, usually the first AUG codon in the mRNA sequence.

Displays that do not support animated GIFs show only the first frame.

Older decoders will simply render the first frame of the animation.

In an inertial frame, Newton's first law ( the law of inertia ) is satisfied: Any free motion has a constant magnitude and direction.

According to the first postulate of special relativity, all physical laws take their simplest form in an inertial frame, and there exist multiple inertial frames interrelated by uniform translation:

Within the realm of Newtonian mechanics, an inertial frame of reference, or inertial reference frame, is one in which Newton's first law of motion is valid.

However, the principle of special relativity generalizes the notion of inertial frame to include all physical laws, not simply Newton's first law.

Newton viewed the first law as valid in any reference frame that is in uniform motion relative to the fixed stars ; that is, neither rotating nor accelerating relative to the stars.

Hence, with respect to an inertial frame, an object or body accelerates only when a physical force is applied, and ( following Newton's first law of motion ), in the absence of a net force, a body at rest will remain at rest and a body in motion will continue to move uniformly — that is, in a straight line and at constant speed.

* relativity of simultaneity ( simultaneous events in one reference frame are not simultaneous in almost all frames moving relative to the first ).

In 1764, James Hargreaves invented the spinning jenny, the first practical spinning frame with multiple spindles, in the village of Stanhill, Lancashire.

The format of a PDU frame is identified by the lower two bits of the first byte of the control field.

One of the first applications of key frame animation was the award-wining 1974 animated short film, Hunger.
