Connection of impost with main supporting profile Connection of an impost with the main supporting profile comprises an impost holder attached to the impost. The main supporting profile has through holes, through which self-tapping fasteners are pulled so that protruding parts of each self-tapping fastener are arranged between the plane of the inner surface of the impost and the plane of the outer surface of the impost holder inserted into the impost. This provides for simultaneous fixation of the impost holder to the impost and the impost with the impost holder to the main supporting profile. The impost holder has appropriate longitudinal grooves for each self-tapping fastener. The impost holder additionally comprises a base arranged between the main support profile and the impost, having vertical boards that cover the impost from outside. |

Method of mounting door at car body Invention relates to automotive industry. Proposed method comprises mounting door holding fixture, fitting side door thereat, welding side door top and bottom hinge fixed links to car body, removing said fixture and upsetting side door relative to car body. Side door upsetting us performed after welding side door bottom hinge fixed link welding. Upsetting is executed by force directed opposite the door gravity force direction but prior to welding side door top hinge fixed link. Upsetting force is selected from expression: P×L/L1<P1<1.2P×L/L1, where P is door weight acting at door center of gravity, P1 is door upsetting force, L is distance from door center of gravity to point "K" of car side door bottom hinge, L1 is distance from point "K" of car side door bottom hinge to upsetting force application point. |

Window spacer comprises the first extended strip with the first edge stretching along the first side of the spacer and with the second edge stretching along the second side of the spacer, the second extended strip with the first edge stretching along the first side of the spacer and with the second edge stretching along the second side of the spacer, the first extruded side wall stretching from the first extended strip to the second extended strip. The first wall is located closer to the first side of the spacer than to the second side of the spacer. The first wall is displaced from the first edge of the first extended strip and from the first edge of the second extended strip by the displacement distance. The spacer is made with the second extruded side wall stretching from the first extended strip to the second extended strip. The second wall is located closer to the second side of the spacer than to the first side of the spacer. The second wall is displaced from the second edge of the first extended strip and from the second edge of the second extended strip by the displacement distance. |

Wear-resistant translucent panel Wear-resistant translucent panel 1 comprises the left 2 and right 3 sheets from a translucent material of higher strength and operational reliability. A tight profile is installed between sheets along their perimetre. Along the inner circuit of which there is a boxy profile 5 arranged with a cavity 6 filled with a moisture-absorbing composition 7. Translucent sheets are joined to each other by means of screws 9, which fix the sheets together on the tight profile 4. A wear-resistant high-module polymer film 10, 11 is applied onto outer and inner surfaces of translucent sheets 2 and 3. The translucent panel is fixed into a standard profile from PVC, forming a window frame. Besides, a low-emission coating is applied on the film on the inner surface of light-transparent sheets. |

Device to retain and rotate winding pipe and plant used at home and comprising such device Device to retain and rotate a winding pipe of a movable screen comprises a driving mechanism equipped with an output shaft. The driving mechanism is inserted into the winding pipe via the first end of the pipe as capable of rotation of the pipe by means of the output shaft. The device is arranged with a tip forming a support for the pipe. At least the covering part of the tip stretches in axial direction from the second end of the shaft and in direction of its first end to the level of arrangement of at least a part of the output shaft. |

Mechanical lifting-rotary gates Gates comprise a support box, an overlapping monolithic plate, lever mechanisms, connection hinged joints and a drive. Two sides of the plate in its lower part are connected by hinged joints with two connecting rods of the drive. On the upper parts of these sides there are two sliders fixed rigidly and having a circle shape with parallel cut segments. On side walls in the upper part of the box there are two guides fixed with slots in each of them, in which sliders of the monolithic plate are placed. The upper part of each slot of the guide ends with a cylindrical surface, the inner diameter of which equals the diameter of the slider circle. The width of the slots is equal to the remaining part of the sliders' circle. The lower part of side walls of the box is equipped with two fixed stops. |
