ELLIPSE VS CIRCLE

ELLIPSE VS CIRCLETo use a bike instead of round sprocket Ellipso suggested in 1892 Professor V. Prusakov. He decided to put the rods along the minor axis of the ellipse that has allowed more efficient use of the power of the cyclist. Experiments have shown that even an inexperienced rider on a machine with the elliptical sprocket expends energy approximately 30% lower than on moving with the same speed filemashine with a round sprocket. And according to the American engineers, the use of oval zubchatki increases the average speed of a cyclist by about 14%.

FROM THE IDEA TO “BOUZOUKI”

FROM IDEA TO Typically to achieve the necessary alignment of heavy fighting model of the micro retracts in the cutout of the front edge of the wing. This leads to some loss of strength and complication of manufacturing technology, and access to the engine for maintenance is much more complicated. So I had the idea to implement the idea of forward-swept wing is given in the “M-K” № 7 for 1988. Front and rear edge of the wing of the new models are made by gluing pine veneer (thickness of 2-1. 5 mm) on the mandrel with the subsequent cutting on a lathe to the required edge thickness. The bonding is conducted on the PVA. Mandrel is more practical to manufacture of chipboard, and in the mounting position and clamp the veneer pack to apply a lacquer coating to facilitate removal of the part after drying.

CUTTER FOR PAPER

CUTTER FOR PHOTO PAPERProcess modifications and finishing of the photograph necessarily involves pruning. It is also necessary when a label image on a piece of cardboard for participation in exhibitions. The operation itself is simple. But if it is executed carelessly, it may decrease the impression of a photograph, despite its artistic merit. Truly “a spoon of tar spoils a barrel of honey”!

HOME TRAVELLER

HOME TRAVELLERWhat tents are not released industry! Single and multi, winter and summer, canvas and nylon… nevertheless, tourists continue to actively develop and produce their own versions. And this is understandable: after all, a good, comfortable tent will not only protect from the weather, but also allow you to fully relax, to rejuvenate after a hard day transition.

BIKE

Exercise BIKEMorning gymnastics, running, lignite winter and summer Hiking trips, Cycling is an effective means of health promotion.
However, the bike largely depends on St of road traffic, the vagaries of the weather. In such cases, an exercise bike, a simple design of which want to offer. It is simple and affordable to manufacture, easy to operate, has a small weight (within 10 kg), it will be a great addition to any apartment,because it takes up little space {300X1300 mm). The Assembly will not require much time or scarce materials. And that is important — the bulk of it is… the bike itself, and any available home. Turning it into a simulator takes literally two to three minutes and is reduced to the removal of the front wheel and securing the fork ka stand simulator.
