GLASS CARE

GLASS CARERemember: it was not cold in your house last winter? Do not rush to blame the heating system, even if it furnace: victoriat room can and Windows. Check to see if the putty on the frames and I wanna see if she cracks through the thin slit between the glass and the wood heat is rapidly going out of the house and cold air is not less noticeable comes inside. The measurements indicate, through window and door openings can dissipate up to 2/3 of the generated heat-generating appliances heat. That’s why remaining before the real cold days are useful to restore the integrity of window glazing. As describe in detail. Our tips will be useful for individual developers, and those who want to make a greenhouse or glasshouse.

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.
