Patent DE-2460306-A1 (DE)
Title: Transformer in two sections on separable mechanical mountings - forming part of a security alarm system
Inventor: WUERFEL WOLFGANG
IPC: H01F38/14
Filed: 1974-12-20
Abstract: The application is principally to security systems for doors and windows, and is intended to improve upon the electromechanical contacts hitherto employed for such duties. The transformers comprises two separate core sections with windings mounted on mutually movable parts of the mechanical structure to be supervised, for example on the window and its stationary frame. As the transformer sections can be be completely encapsulated they can also be used where otherwise weather conditions would make for unreliable operation. By removing mechanical contacts the malfunctions caused by contamination of the contacts are eliminated. The mounting of the components is also made easier by reducing the need for accuracy.

Title: Permanently magnetised keys for magnetic lock - have diminutive dipoles, 2 to 3 mm, under solid material surface to align lock elements
Inventor: PERKUT BRANKO R
IPC: H01F13/00
Filed: 1975-12-30
Abstract: The main patent described a method of forming diminutive magnetic dipoles (as short as 2 mm) in separate locations under the surface of solid material. The effect of each dipole is exclusively local, and they do not interact. Keys permanently magnetised with such sets of dipoles can be used to operate magnetic locks. Two locks are presently described. In one, the lock (14) is controlled by pairs (24) of small balls, each pair in its own chamber (20). When the magnetic key is inserted, each pair of balls aligns with a dipole. Thus positioned, the balls are opposite cavities (26) in the moving part of the lock, which is thus released. In the second lock, the dipoles are used to orient permanently magnetised elements on their pivots.
