Drilling rigs

-

Drilling rigs (hydraulic impact drilling machine, hydraulic ram, Wolski taran) - a drilling rig using a water hammer to increase the impact force of the bit in the borehole. Constructed in 1902 and patented by Waclaw Wolski. History

Taran Wolski used a drilling rig located in the borehole. After a rapid stop of the flow of the scrubber (due to the sudden closure of the valve), its kinetic energy was transmitted to the drill which hit the bottom of the drill hole.

Taran Wolski has been practically used in Polish oil mining for several years. In 1903 a well was drilled in Pogwizdow, and in the years 1905-1908 several deep wells in Boryslaw (eg Vilnius). The device was also used outside Poland, among others. in Groznyn, Beckum and Haren.

In the later years, the barbed was discarded because all patents related to it were bought out for 600 thousand. By the leading drilling companies: Internationale Tiefbohrgesellschaft Raky of Erkelenz and Deutsche Tiefbohrgesellschaft of Nordhausen, which, in the face of the loss of the European market, blocked the Wolski invention.

He led to the murder of Rafael Trujillo on May 30, 1961, but he could not use this to overthrow his followers. He failed to arrest them along with Trujillo's sons such as Ramfis. Ultimately, the conspiracy ended with the conspirators' defeat when Zacarias - chauffeur Trujillo - survived the presidential bombardment and handed over the drafts of the bombers and Arturo Espaillat informed Roman about the death of the commander - at the sight of Arturo Espaillata Roman revealed ...

Myrmex Indikos

Myrmex Indikos, pol. Indian ant - an alleged species of gigantic ants (according to Herodot's description, larger than foxes, but smaller than dogs). The earliest mention of these creatures is dated to the fifth century BC, and its author is Herodotus. According to her, these ants inhabited the deserts of Persia and India and extracted gold from their sands. Several such creatures were kept in the residence of the King of Persia. Gold was to be obtained by caravans made up of several camels in the heat of the day, when the ants were protected underground. You had to do it quickly, because the ants sensed the smell of people and went on the pursuit, and they were deadly dangerous. This story is confirmed by the next accounts: Nearchos, one of the army officers of Alexander Macedoński, and Megastenes - a historian and traveler. The fragment of the Megasthenes (IV-III century BC) preserved in fragments can be seen in the underground mines at the foot of the mountains on the easte...

Names of streets and squares

The names of the streets and squares were originally of a topographical nature, that is, they informed about: Researchers propose two names for these toponyms - urban or plateonimy. S. Urbańczyk points out that the older names were spontaneously formed and sprouted in the daily lives of the inhabitants of the place. The information contained herein was related to the characteristics of the place (eg appearance), important road directions (geographic orientation) or values, functions and economic meanings called places / objects in the settlement for the inhabitants' lives. Former names are protected by law, but are often not respected by managers of the municipality, county or province.
