It is known that in the process of operation of car batteries is required from time to time to do preventive charge-discharge cycles to prevent sulfation of the plates and thereby increase their service life. There are lots of devices, including homemade (see the journal “modelist-Konstruktor” No. 9— 11 ’01), through which the battery is initially discharged to 10.5 V with a current of 1/20 of its capacity and then the voltage on the terminals is communicated during the charge-discharge cycle to 14.2 to 14.5 V. And the ratio of the charge-discharge current components are in the majority supported almost perfect — 10:1, and the pulse durations of the charge-discharge — as 3:1, but…

Oddly enough, but until 1963, the famous Creator of the most prestigious racing cars, Lamborghini Ferruccio engaged in production… tractors. The reason for such a radical change it was a youthful fascination with the designer — in the distant postwar years he was engaged in the conversion of the serial “Fiats” in sports cars.

Busy with household chores or interesting conversation, we forget, for example, on a boiling kettle. Time to remind him maybe a simple buzzer. However, the oscillators sound frequency (e.g. multivibrators) based on transistor logic or integrated circuits do not always meet their creators. The simplest devices give a smooth tone, barely visible against the background of everyday noise, and sudden and loud “beep-beep” of a more complex designs can scare.
Firm history John North Willis began with the acquisition in 1908 of a small automobile company Overland, which became known as Willys-Overland. The new firm first specialized in the production sports cars with 4-cylinder engines and planetary transmissions, however, soon created cars with a 45-horsepower motors and WILLYS OVERLAND SIX SIX. In 1913 the company sold about 35 thousand cars entered if the number of the leading automobile companies of America.
How to start a designer? In Latin the word “design” (constructio) means the preparation, construction. In technical language it includes concepts such as diagram of the device and operation of a machine, structure or site. Designs also referred to as the machines, structures or individual components and their details. In addition, the concept of “design” leads to and provides a very specific arrangement of parts and elements of the machine, method of connection, forms of interaction and, of course, the material from which the individual parts (elements) of the structure needs to be manufactured.
For transportation of large cargo by land over distances of hundreds and thousands of miles of not-yet-invented method than the railway. It accounts for in the country about two thirds of total turnover. In the ninth five-year plan to build new roads, increased capacity and capacity podvesnoy composition.
Strategic bomber b-47 STRATOGET. Work in the field of creation of jet engines suitable for use on aircraft, began in the USA in 1941. The design of new power plants engaged in the company “Allis-Chalmers”, “Westinghouse” and “General electric”, which was part of the so-called Committee of Durand. The first two working under orders of the Navy, and the third was designed turboprop engine for the air force. All three firms had a very vague idea about gas turbine engines for aircraft, their main activity was the production of industrial turbines. Therefore, the work progressed slowly, which naturally did not suit the military.
…There is a truth familiar to everyone since childhood. To get a good harvest, the plants during their growth it is necessary to give enough moisture. And if in the Central latitudes of the European part of our country plants can quench their thirst with rain water, in Kazakhstan, in Central Asia the picture is different. There is a lot of sun, you can obtain and get! incredible yields, but at the same time, there is not enough water.
This prestigious car developed by specialists of the Japanese company Toyota Motor Co. Ltd. was first shown to the public at the motor show in Tokyo in 1999 as a promising concept car. The history of the brand LEXUS, used Toyota firm for the most prestigious cars began more than a decade ago when this Japanese firm began to produce a purely export model badged LEXUS. The first such machine — LS400 — appeared on the automotive market of the United States in 1988. In 1997 Тоyota LEXUS released the second generation with a more powerful engine.
