Abstract: A device for the safe descent of people or cargo along the cable, for example, for the salvation of people in case of fire in high-rise building. To provide the salvation of a few people during the same rescue operation, the device ensures movement along the cable in both directions, downwards and upwards. There is no need for any extensive preparation before using the device. The cable, with or without a handing device, is fixed in the point of lowering, dropped downwards with the weight and then is reeled three times upon the contact disk. Such connection ensures moving the contact disk along the cable without sliding.

Abstract: A rescue device for a victim buried in snow because of snow avalanches, providing connection the victim with outside fresh air for breath, withdrawal and neutralization of exhale air and signaling position of the victim under the snow. The device includes an air canal—telescoping flat-spring structure that drills a hole in snow and connects the victim with open air above the avalanche. The canal includes immobile and moveable housings having hinge connections to outside and inside spires of the spring, accordingly. A blade removing the snow, when the canal is being created, and intensifying movement of the air inside the canal, is attached to a shaft of the electric motor, which in turn is attached to the moveable housing. The blade has a cover avoiding penetration of the snow inside the canal.

Abstract: The system for safe descent of people or cargoes, for example for rescuing people in case fire in high-rise buildings consists of a device for control movement along the cable, the cable itself and a connection between them. There is no need for any serious preparation before using the system: the cable by means of hanging device or without them is dropped downwards or the cable is discharged from the cross bow to the lower object where the harpoon fixes itself. The control over the speed of the descent is performed automatically by means of electric frictional brake. Required energy is used from energy weight of descending object. The rotor of a generator of direct current and the axis of the movable disk of the brake is connected with the axis of the contact disk through the reducer. Three revolutions of the cable are reeled upon this contact disk.
