摘要:
A closure, particularly for closing construction and technological apertures, the principle of which consists in that on the bottom side of the cover of the closing hole a rocker arm is pivotally mounted, the functional part of which in the closed position of the cover rests on the opposite element, which is anchored in the closing hole. The rocker arm is pivotally attached on a pin that is anchored by means of brackets to the bottom part of the cover. The axis of the pin, on which the rocker arm is mounted, may be either parallel to the longitudinal axis of the closing hole or perpendicular to it. The rocker arm and the rocker lug are balanced relative to the pin so that the closure is maintained in a closed position.

The essence of the storage system lies in the fact that it is provided with at least one rack structure (6), which is provided with at least one vertical shaft (15), in which vertical toothed rack (25) or riser chains (32) are fixed, and at least one rack an aisle (11) in which the horizontal longitudinal rails (21) are fixed, as well as at least one truck (12) with a main bogie (1) for horizontal movement and a second bogie (2) with gears (24) for vertical movement of the truck (12). ). The essence of the truck for the storage system is that it is provided with a storage surface which is provided with at least one gripping mechanism, a main bogie (1) for horizontal movement of the truck and a second bogie (2) for vertical movement of the truck, where the second bogie (2) is provided with gears (24), the mutually independent bogies (1,2) being provided with a first drive (13) and a second drive (17), and the truck being equipped with control electronics (20), a power supply system and a communication module (31). The truck for the storage system can be provided with a second bogie (2) for lateral movement of the truck (12). The essence of the rack construction of the storage system lies in the fact that it consists of interconnected rack webs (34) and rack shelves (35), while in at least one vertical shaft (15) are fixed toothed racks (25) or riser chains (32), which pass through gaps (29) in horizontal longitudinal rails (21) which are accommodated in at least one rack aisle (11).
摘要:
The essence of the invention in that it contains an infrared thermographic camera and at least one safety reflective element, located on an object whose visibility is ensured, while the functional optical surface of the safety reflective element is located in the field of view of the infrared thermographic camera and the infrared thermographic camera is located in the field of reflection of the sky from the functional optical surface of the safety reflective element. The subject of the invention is also an infrared safety reflective element, the essence of which is that the functional optical surface of the safety reflective element has a spectral reflectance in the band 1 to 15 µm higher than 0.5, while the area of the functional optical surface is greater than 25 mm2.
摘要:
Parachute rescue system, destined for aircrafts with a rotating blade, as are especially helicopters or gyroplanes, consists at least from one rescue parachute (1), located before the activation of the system in a mounting box (2) and is furnished by a rocket engine (3) or by another driving mechanism connected by an activating wiring (5) with an activating handle (6) installed within the pilots reach. One or more single rescue parachutes (1) are fastened through for example a ring swivel-type head (80) round the rotor (16) of the aircraft with a rotating blade (14) under its revolving blades (17) by at least one derrick guy (12), rising after the system activation through these revolving blades (17) upwards. The derrick guy (12) is concurrently furnished by a rope swivel-type head (8) in order to eliminate the transfer of rotor revolutions (16) to the parachute ropes.
