Aliens



Aliens
We are alone in this world? This is a simple question that all the people do. I will explain it in this essay. I was researching in several pages in internet and I found you arguments that whether or not aliens? Some people said that they saw flying saucers but that they really saw airplane or a balloon.
Years ago in a newspaper public that has an alien in New Mexico who fell and the organization of men in black go to that place to collect the rest of the evidence of the accident and to talk with the persons that saw the death aliens. There are photographs of the autopsy of two aliens and one of them was black and white, slender bodies, four fingers, heads and their large eyes, small nose holes and had a hairline by mouth. The NASA have occult the bodies of this visitors in a special room that they have in there’s quarters (1). Other thing that I research is that a man called James Noce who has an age of 72 year say all about the area 51, he said that in that place they not work with any alien and they have that area to prove an airplanes but as we know if maybe they erased the memory of him? (2)


On July 8 of 1947, an alien striking in New Mexico but this time it striking on the farm of Mark Brazel. Because of this, all the newspaper wheresaying that we have a visitor of an other planet. Additionally, the militias confirm what the newspaper said (3). Although, it can be real or a fraud? Well the case of Roswell not will be the only exception of what ever hypothesis unbolts doubt. This will be a complot of the government to make the tourist go to that place and increase they economic (4).
However, in Brasilia they saw flying saucers, too. Some take photos of it but can´t see well because is in the night. All only saw mysterious light that are in the sky. Also, they saw some signals of the visitors (5). I think that this are good reason to think that are someone or something out there but others people think that there are not aliens in the galaxy, they think that nothing is there but they never ask themselves : We are alone………?

Material Handling in Mining – A Case Study

Technical Seminar 1999

Great effort was made to develop a suitable mechanical brake system. The temperatures generated by the mechanical brakes during an emergency stop create a challenge regarding the selection of the brake lining material and the brake disc Conveyor Belt ST-7800 design. Also, in the interest of safety, almost all brake control components are fully redundant. Conveyor Belt

Brake Caliper Assembly

Conveyors CV-005 and CV-006 are equipped with steel cable belting rated at ST-7800. This marks a new world record for conveyor belting, assuming the distinctions of the world’s strongest conveyor belt from the Prosper-Haniel mine in Germany, which carried the record for the last 14 years. Belt forces will reach 250 tons during running, and can peak at 320 tons during emergency braking. Special attention was given to the splice as the weakest link of the belt. Testing performed at the University of Hanover, Germany showed that the fatigue strength of the splice exceeds 50% of the ultimate brakingstrength of the belt. As a safeguard, a splice failure detection system has been provided for the first time. This system is designed to detect splice elongation resulting from impending splice failure, and to safely stop the conveyor before the damage occurs. Reducers The 2500 kW two-stage helical bevel reducers are the largest reducers ever employed for conveyor drives. At a unit weight of 26 tons, the reducers are fully self-cooling and do not rely on auxiliary devices for temperature regulation. Several studies were made by Universities and scientific institutes to validate the reducer design, such as a heat dissipation study, a finite element analysis of the housing, and a bearing smear study.

Pulleys As another new record, the drive pulleys supplied for the Los Pelambres overland conveyors are the largest conveyor pulleys built to date. The pulleys have a shell diameter of 2,500 mm. The pulley shaft measures 630 mm in diameter. The bearings have an inside diameter of 560 mm. The total assembly weight is 37 tons per pulley. Conclusion The Los Pelambres overland conveyor system sets a new standard for many aspects of belt conveyor design. While it is technically possible to build yet larger systems, it can be assumed that the limits of practicality and economy will not allow pushing the envelope much further.
