AIRBORNE PARAGLIDING

AIRBORNE GLIDERDesign truck for paraglider was preceded by just the fascination of paragliding, which did not come at once. First flew airplanes (and flight certificate), gliders. But one day, fly a paraglider, got into it seriously. I think it is comparable to swimming to sailing. Only even better.

First, like most parable-Aristov, used for takeoff and landing conventional three-wheeled cart. Not going to say much about all her faults (they are known to the pilots para-glider). But the most unpleasant of them tipping forward and sideways with insufficient management skills dome on takeoff and landing. But for experienced paraglider on a truck is not immune from stalling—for example, when a side gust of wind. And this is very dangerous because the rollover more likely, the higher the speed, i.e. during takeoff and especially during landing.

A BELT OF ANTIMATTER

BELT OF ANTIMATTERAround the Earth discovered belt of antimatter.

Likely that You can Wake up and not wonder what happens to the protons that are born as a result of a collision of powerful streams of cosmic radiation with the upper layers of Earth’s atmosphere.

But on Earth there are people, though few, are in search of an answer to this question lose appetite and sleep. Now their house is the holiday, astrophysicists caught in the magnetic trap of the spacecraft PAMELA a particle of antimatter that forms around our planet belt, consisting of a small number of antiprotons.

E-BIKES WITH AUTOMATIC TRANSMISSION

E-BIKES WITH AUTOMATIC TRANSMISSIONFor this development the company JD Europe Components GmbH received the gold medal of the Eurobike Award 2011

Automatic transmission is called Automatic Gear Transmission (AGT). New bike system is essentially a computer that continuously receives information from multiple sensors, learning speed, torque, number of revolutions per minute.

Based on these data, the system constantly calculates the optimal gear ratio and smoothly poltical suitable gear. There is a semi-automatic mode, when the rider shifts gears by pushing the “plus” and “minus”.

FABRICATION OF NANOFIBERS

PRODUCTION OF NANOFIBERSFound technological method of producing nanofibers.

Engineers from the University of North Carolina have modified a known method of manufacture of nanofibers, significantly increasing the speed of their output.

The process of forming fibers with a diameter of ~100-1 000 nm of polymer solutions is called elektrodrazenie. In the design of a typical setup for “spinning” stand out a pump that provides a continuous flow of liquid to a conducting needle, collecting plate and the high voltage source, generating a field between the needle tip and the plate. The solution is in contact with a metal needle, charged, and put into it the charges are accelerated by the electric field and involve in the movement of the surrounding substance, whereby the fluid is accelerated uniformly in the sky, in a thin stream. In the interelectrode gap, the solvent partially evaporates, and the stream turns into fiber, which is deposited on the plate and creates a porous layer.

FLUORESCENT LAMPS

FLUORESCENT LAMPFluorescent lamp — gas discharge light source in which visible light is emitted mainly by the phosphor, which, in turn, glows under the ultraviolet radiation of the discharge; the discharge also emits visible light, but to a much lesser extent. Luminous efficacy of a fluorescent lamp is several times greater than incandescent lamps of similar power. The lifetime of fluorescent lamps can exceed 20 times the life of incandescent lamps while ensuring sufficient quality of power supply, ballast, and compliance with restrictions on the number of on / off.

MIKROAVTO FOR TWO

MIKROAVTO FOR TWOFrame double machine, dubbed “mouse”, welded from thin steel tubes. Front axle (Fig. 3) assembled from beams, two eyes and swing units of the front wheels. Axle are the axle adapted to pivot the sleeve at an angle of 98 ° and welded to it. Pivot arm has a bend of sheet steel with thickness 1.5 mm; pivot bushing it is attached by welding at an angle of 110°. Ring tail joints at the ends of the swivel levers are cut from steel pipe ø 12 mm.

The pivot bushing is provided with bronze bearing liners, through which is passed a pin pivotally connecting the sleeve with the lug of the front axle.

Wheel — steel, turned. In each are placed on two bearings (202 and 201), closed Salnikova washers.

The hub is fixed on the axis of the axle nut. Between the bearings inserted spacer.
