Abstract: A magnetic descent control device is disclosed. The device comprises an input shaft affixed to a rotating driven sheave acting as a drive assembly, which grips a cable guiding the descent path of a body carrying cage. The input shaft has a shoulder upon which rests a rotor. The rotor is encased within a front and back enclosure of conductive material. Disposed along at least one surface of the rotor and/or at least one of the conductors, is a series of magnets such that rotation of the rotor relative to the conductors creates relative motion between the magnets' magnetic field and the conductor inducing eddy currents in the conductor that oppose the magnetic field creating a rotational braking force. As a result, very precise and/or controllable descent may be obtained over a broad range of descent angles and/or distances with little or no mechanical wear or risk of overheating. Preferably, the sheave gripping the cable may have a circumferential groove to better improve traction and grip of the cable.

Abstract: This specification describes a portable manually operated rescue and lowering device. It consists of a coaster-brake bicycle hub with its flanges extended enough to form a drum to accommodate about 40 meters of fine aircraft cable. To permit hand operation a novel brake securing and releasing lever replaces the standard bicycle sprocket. This modified assembly is mounted into a rigid frame so that the free end of the cable proceeds up away from the hub to be secured to a building part or object within the building. A fastener for hooking onto a sling is hung from the frame by means of a cable--the length of which is correct for holding a user within easy reach of the brake securing and releasing lever. With this lever, the operator can cause the cable to unwind quickly or slowly or to brake to a complete halt. To prevent the cable from accidentally unwinding constant counterclockwise tension is provided to the lever by two springs.

Abstract: A lightweight apparatus for lowering a load at a controlled rate utilizes an elongated load-carrying strand and a slider assembly mounted on the strand to support a load for controlled downward sliding movement along the strand. The slider assembly includes a brake which is manually operable to control movement of the slider from a complete stop to substantially free fall conditions. In a preferred embodiment, the brake is spring-loaded to an intermediate position to permit a load to be lowered at a safe, relatively slow rate without actuation of the brake. When such preferred embodiment is used by a person to lower himself, a brake control lever may be manually displaced from the intermediate position to increase or decrease the rate of descent.
