Abstract
Abstract An arresting device for the braking of aircraft or other vehicles by means of an arrester device embodying a cable, net etc., connected to braking means, and which means includes a brake that has a brake drum that is caused to rotate before and during contact of the cable or net with the airplane, the rotation means for the brake drum being power means such as one or more electric motors, the speed of the power means and hence the rotative speed of the drum being controlled to cause it to correspond to the approach speed of a plane to be arrested so that the jerk on the cable during the arresting operation will be minimized.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
161 words
A device for the braking of vehicles such as airplanes, by means of an arrester such as a net, hook, cable, or the like connected to arrester cables which during braking are arranged to unwind from brake drums connected to brakes, the device including a brake drum that is caused to rotate before and during contact of the net, cable etc. with the airplane, power means for rotating the brake drum at a speed corresponding to the approach speed of the airplane so that the least possible jerk is applied to the arrester device, a cable of rectangular cross section being wound around the brake drum that is connected to the arrester device by means of a coupling, such coupling being coaxial with and located at one end of the drum and consisting of a component which is connected to a cable and is rotatably mounted in and axially fixed to a stationary component that is fixed to the arrester device.
Claim 2
Independent Claim
161 words
A device for the braking of vehicles such as airplanes, by means of an arrester such as a net, hook, cable, or the like connected to arrester cables which during braking are arranged to unwind from brake drums connected to brakes, the device including a brake drum that is caused to rotate before and during contact of the net, cable etc. with the airplane, power means for rotating the brake drum at a speed corresponding to the approach speed of the airplane so that the least possible jerk is applied to the arrester device, a cable of rectangular cross section being wound around the brake drum that is connected to the arrester device by means of a coupling, such coupling being coaxial with and located at one end of the drum and consisting of a component which is connected to a cable and is rotatably mounted in and axially fixed to a stationary component that is fixed to the arrester device.
Claim 3
Dependent Claim
25 words
A device according to claim 1, characterized in that the coupling is located axially outside and some distance away from the adjacent coil of cable.
Claim 4
Independent Claim
97 words
A device for the braking of vehicles preferably airplanes by an arresting device such as a net, hook, cable or the like which are adapted to unwind from brake drums, characterized by a cable which is wound around a brake drum and which cable is flat and is connected to an arrester cable, the brake drum before and upon contact between the aircraft and the arresting cable being arranged to rotate by means of a motor with a speed adjusted to the landing speed of the aircraft in order to reduce the shock on the arresting cable.
Claim 5
Independent Claim
97 words
A device for the braking of vehicles preferably airplanes by an arresting device such as a net, hook, cable or the like which are adapted to unwind from brake drums, characterized by a cable which is wound around a brake drum and which cable is flat and is connected to an arrester cable, the brake drum before and upon contact between the aircraft and the arresting cable being arranged to rotate by means of a motor with a speed adjusted to the landing speed of the aircraft in order to reduce the shock on the arresting cable.
