"The very nations that have made greatest progress in their development during last century are justly those three countries which have rewarded their inventors for inventions done". Evans, J. Chicago Steel Foundry Co. v. Burnside Steel Foundry Co., 132F. 2d 812, 816; 56 U.S.P.Q., 283,287 (7 th Cir. 1943)

I have a lot of secrets in field of chromatography!

One of them is attainment of maximum possible efficiency of chromatographic column (Hayrapetyan's Effect).

For this purpose new basic technology chromatography - Chromabarography is offered. (Russia patent Chromatograph of A. S. Hayrapetyan). The essence of new basic technology of chromatography - Chromabarography - is provision of optional conditions of analysis by keeping unchanged linear rate of an imaginary point - zone of sample moved in time by carrier-gas from inlet to outlet of chromatographic column, ∆ p being kept constant at its ends during whole cycle of analysis, by which a maximum column efficiency (Hayrapetyan's Effect) is attained. From practice of international trade of licenses it is known that expenses for acquisition of a new technology, know-how and engineering at their mean sizes constitute a legible part of income main factors taken into account in adoption of a decision and activity planning by a firm are: ◊ innovation; ◊ in-time outstripping of competitors; ◊ technical superiority of items. Companies usually tend to penetrate into new markets as early as possible (though not necessarily first) with a product of a quality as high as possible, and then accommodate their items to market demands ("Perkin Elmer").

To copy, means always to catch up. To buy a license means to get to level of latest achievements of world science and practice in shortest time and with least expenditure of forces and means. An example of this may serve Germany, Netherlands and Japan, burst ahead in some fields of science, technique and industrial production, mainly on account of acquisition of licenses for right to use foreign patents and know-hows.

The essence of other patentable technical solutions - inventions, developing basic technology, is not described as they are not patented. Their patenting only in Armenia is not expedient for following reasons:

Coin in – spin – hold your breath......Watch those symbols.....Will it or won’t it? Heart racing ..... dials slow down and IT’S A WINNER!!!! Three bells in a row! But wait – there’s more to come – The screen is flashing, bells are ringing, and yes, it finally happened – YOU WON THE JACKPOT!!

To play slots, you click “coin” icon to specify value of credits you want to play with. The payout scale for slots is shown at top of slot machine. This is heart-stopping moment that makes slot machines irresistible; this is adrenalin-pumping experience that makes it impossible for slot machines to go out of fashion.

Slot Machine History begins in San Francisco USA, when a 29 year old mechanic by name of Charles Fey built first slot machine in history in 1887: Liberty Bell, and hit public’s imagination when they were installed in Flaming Hilton hotel in Las Vegas.

The invention, hand made, in a small machine shop, has paved road to gambling industries as we know them today. Charles Fey was not only inventor, but also first slot machine owner and operator, as he placed his work in pubs. The history of slot machines has only then begun.

An American invention, slot machines have since become very popular all around world. The most notable places include Europe, Africa, South America, Asia, and Caribbean.

Often referred to as ‘one-armed bandits’, their magnetic appeal is hard to define. Is it hypnotic effect of spinning symbols? Or incredible excitement of bells and flashing lights which herald big win? Or just fact that they work purely on gambler’s best friend – pure chance? Whatever it is, slot machines are essence of gambler’s dream – dream of that one big life-changing win.
