ACTION OF HIGH-ENERGY ELECTROIMPULSES ON METAL MELTS
Action of superhigh-energy electroimpulses on crystallization melts various steels and alloys for the first time was comprehensively explored by academician D.I.Korneev at making of new methods of electro slag welding [1-3]. During a series manifold physics of metals experiments by him, the new effects varying structure and properties recrystallization of metals were unclosed. Among the data crystal physics phenomena’s are oozed, on the practical value, mechanics and corrosion effects. Thus successfully solved a problem of technological overlapping of two various physical processes - electro slag welding and temperature cycling of annealing. Scientific - applied aspects of the phenomenon of electro current pulsing processing /ECPP/ metal melts in modes of ultrahigh energies consist in opening the key opportunity of re-structuring metal matrix with giving of necessary service performances. In too time ECPP solves also a series of special problems, allowing gaining welded joints with high stability of metal of a seam mechanical and corrosion fractures without the subsequent thermal processing.

ON THE PROBLEM OF CRYSTAL METALLIC LATTICE IN THE DENSEST PACKINGS OF CHEMICAL ELEMENTS
The literature generally describes a metallic bond as the one formed by means of mutual bonds between atoms' exterior electrons and not possessing the directional properties. However, attempts have been made to explain directional metallic bonds, as a specific crystal metallic lattice. This paper demonstrates that the metallic bond in the densest packings (volume-centered and face-centered) between the centrally elected atom and its neighbours in general is, probably, effected by 9 (nine) directional bonds, as opposed to the number of neighbours which equals 12 (twelve) (coordination number). Probably, 3 (three) "foreign" atoms are present in the coordination number 12 stereometrically, and not for the reason of bond. This problem is to be solved experimentally.

PLASMA-JET ENGINE WITH CLOSED-CIRCUIT ELECTRON DRIFT
SUBSTANCE: engine has at least one compensating cathode with outlet aperture positioned towards accelerated plasma flow and anode unit incorporating annular discharge chamber with ionization and acceleration zones formed by internal and external annular walls, and magnetic system with internal and external magnetic poles; output aperture of compensating cathode is disposed in zone confined on one end with external magnetic pole plane and on other end, with conical surface crossing the line intersecting interface ionization-to- acceleration zone and external annular wall; angle of maximum 30 deg. is formed here between this conical surface and external magnetic pole surface. External pole has annular projection on side of accelerated plasma flow whose end surface is made in the form of cone.

USB photo scanner
Photographs are, for some of us, our most prized possessions allowing memories to be taken in a snapshot, saved and shared. With the digital age now upon us, storing images and pictures onto digital media is much preferred to preserve photographs and memories, ensuring that you have a backup and cannot be damaged by lying around in a box. Transforming normal photographs into their digital equivalents is no easy task, but it has now been made easy thanks to the USB Photo Scanner. Armed with a 5 Mega-pixel CMOS sensor, scanning a photo takes a few minutes, much faster than most modern scanners. As you filter each photograph into the tray and slide them into the converter, you press...
lightest phone
Mobile phones used to be assessed on how small they were, with phone companies competing against each other to create the smallest handset on the market. Mobile phone features used to take less precedence over the size of the phone, but as consumer needs evolved the phones evolved in parallel. Phones were now being crammed with as many features as possible, pushing both the size and weight of handsets back to a similar level when mobile phones first emerged onto the market. In the modern world, achieving the correct balance of size and features is critical. Sizes and features are constantly being designed and re-thought and Modu have now released the world's lightest ever mobile
spinning wall
Conserving space is very much a must for those living in small apartments or flats, where space is few and far between. Therefore it is imperative to take advantage of the space you do have, and create an illusion of having more space than you actually do. Many use subtle colours on their walls, or mirror effects to achieve this illusion, but a practical solution has only entered the scene recently, in the form of the TurnOn Multi-Functional Spinning Wall. The Wall is essentially a room which makes use of the ceiling also - allowing for additional space and room. In order to feel the new dimension of space you climb into the hamster-like wheel and then roll it you’re your desired...
Air compressed driven watch
Watches are typically battery driven meaning that you have to change batteries often during your watch's lifetime. There have been few innovations on the mechanics of watches in recent years, but there is now - and it comes courtesy of the Urwerk 202. The 202 holds no battery, but functions by making use of compressed air. The internals of the watch are waterproof, allowing the built-in turbines to rotate based on temperature changes. In an effort to increase the lifespan of the watch, there is a switch on the back which can be set at one of three positions - each controlling the turbine speeds to a different degree. "In addition, the reading manner is fairly innovative.
TELIVISION
The televison set was invented by not one person but a group of numerous personnel. The principal idea was based on photoconductivity of the element selenium, founded by Willoughby Smith in 1873. All televisions make use of an image which is scanned to produce a representation time signal, which is then reversed and decoded by the human eye. On 26 January... read more
So what exactly is a patent? A patent is a legal right which offers the patentee a monopoly to manufacture, utilise or sell their own invention, legally, over a specific amount of time. A patent is accepted and issued in exchange for the invention specifics.
Patents are not mandatory; however it is important to stress the importance of engaging in the patent process. Once details enter the public domain regarding the invention, application for a patent becomes invalid. This can, in some cases, allow another person to steal your idea and make profit upon it whilst suffering no legal implications.
