This article discusses the possibility of transmission of electrical energy and / or information to an isolated from the Earth or from another conductive body object on one conductor, and a brief history of this issue
The author of this project hope to demonstrate, that it’s will be possible to use fuller and more comfortable such suppliers of ecologically clean electric energy as wind and waves, and results of human activities, for example, vibration and shaking of means of transport and traffic-bearing surface, when we shall use along with electrical generators, which work from rotation, another type of generators, which work from forward movements – linear generators. In the project, except the description of already known things that it was necessary to make fortunes of this direction of equipment for representation to the reader, it is possible to find also some innovations. So for the first time it is offered to use trees (swing of their branches from a wind) for power generation, a design of a sea raft where the generator isn't shipped in water, balloons as pushers of generators, columns, billboards, and many other things. In some situations the author proposes to use effective, in his opinion, ways of transformation of linear movements to the rotation for use with usual dynamos.
This refers to a can of tear gas. The space in the conventional knife handle is not used. So why not make a hollow handle and insert the cartridge into it. This will enable the reflection of criminal attacks / elements, try not to go to the bloodshed and neutralize it / them with tear gas. If this does not work, then, will remain another strong argument - the knife blade
Usual fastening of two halves of the handle of such knife very inconveniently (watch Pict.7a), and it is possible to lose some precious seconds if it is about self-defense, bringing a knife into a fighting state. After all it is necessary to press to each other halves (1) and to turn the buckle (5), then, after opening of an edge, again to press halves and to turn the buckle. Magnetic fastening is offered (watch Pict.7b). At such fastening, it is possible to open and fix in the fighting provision of a half of the handle much quicker.
There are many options of sets of the knives, spoons, forks and corkscrews combined in one handle or a box. Such things are demanded by the tourists, new settlers and people who are going to present a gift. This product applies for being compact, convenient and simple in use, and to be pleasing to the eye the graceful constructive decision.
Sometimes you need to ensure proper connection elements in electrical and electrical performance. In this case, do not just make soldering or other long-term connection of the wires. Magnetic plugs which conveniently can solve this problem are offered.
Many men wear neckties difficult due to the fact that the tape under the shirt collar create trouble squeezing the neck, down to the feeling of "strangulation" and dizziness. Magnetic attachment can dispense shorter strips extending only to the neck of the semicircle and thus alleviate the problem. Furthermore, such mounting collar decorate beautiful plates. On the principle of magnetic mounting can be done "tie clip" securing the tie to a shirt in the chest-abdomen. Also arranged and magnetic buttons, which can be sewn to the shirt, but you can not sew, but also use them as a temporary support such as "safety pin". The advantages of these fixtures is that they are easy to use.
Researches on sports medicine show that walking and run by a back – forward have some advantages before the usual. Burn more calories, better working muscles and joints. Softer influence from pushes at a landing. Also included in the work and still other muscles (fighting stoop) that walking and running face-forward are not involved. But there is a question how not to be traumatized, having stumbled/having come across something or having got a foot to a hole at such sport, after all not all have eyes on a nape?! This invention is urged to give the worthy answer to this call. Besides, there is an opinion that unusual work for a brain which creates use of the device, can promote its some rest, training and development.
