Title: Rotating cylinder lock with core actuated by magnetic key - has rotating longitudinally arranged magnets acting as tumbler elements
Inventor: BOEVING EGON
IPC: E05B47/00
Filed: 1973-10-25
Abstract: The lock has three rotating magnets which are connected to the locking member which projects along the length of the locking cylinder. This locking member projects into the radial groove in the cylindrical bore of the lock housing. The key is pushed into the key channel and this channel has a groove for preventing the key being inserted in the wrong attitude. Permanent magnets are held in pockets in the key. These magnets are arranged opposite the magnet in the lock. Permanent magnets in the key displace the magnets in the lock which bring the openings into alignment with the projections of the locking member. The locking element is released when the key is rotated. This lock cannot be opened by attempting to sense the positions of the tumberls by special tools. Even if one magnetic tumbler is aligned the remaining rotating magnets are clamped and cannot be rotated.

Title: Grabbing crane control system - uses comparison between winch speeds to adjust speeds of driving motors
Inventor: ROEHL KARL-HEINZ
IPC: B66C13/38
Filed: 1975-01-07
Abstract: The system is for cranes having clutchless two-motor winches for use with grabs or C-type hooks. An automatic control system regulates thespeed of the holding and closing ropes, reacting to measurements depending on the speeds of winch (7a, 8a) or motor (9, 10) shafts. This compares the two speeds, and uses the resultant signal to vary the speed of one or both of the winch motors (1, 2). The system is switched on and off as desired. The motor shafts can be coupled to a differential unit, and a compensation switch is coupled to the differential shaft via a clutch acting as a selector. The switch keeps both motors running at the same speed, dependent on the direction of rotation of the differential shaft, returning to the neutral position on de-clutching.
