Title: Signalling centre for armoured vault - has a jamming system which is activated by the emergency signal centre
Inventor: STOHR HEINZ DIPL-ING
IPC: E05G1/10
Filed: 1973-07-14
Abstract: The blocking lock for the armoured vault is arranged separately and an arrangement enables activation of a safety system to be carried out without additional activation of the switching elements from the vault door. A concealed switching process is used for closing a vault door by means of a necessary and conventional handle. A greater degree of concealment is achieved not only by the use of an emergency signal and auxiliary signalling centre but also due to the elimination of the blocking lock key. The vault is enclosed by the walls of the vault door. The protected vault contains the emergency call and auxiliary signal centre to which are connected sensors for monitoring the critical positions. All signalling circuits are activated before the closing process and the central arrangement is switched on. The final closing which completely activates the central unit can be carried out without obstructions.

Title: Safety cut-out for continuous flow heater - has block shaped insulating channel body with bare heating elements
Inventor: RICHTER HANS HERBERT
IPC: H02H5/08
Filed: 1973-12-03
Abstract: In normal operation the heaters are switched by a water switch responding to a pressure difference, and are switched off in case of an emergency by a safety cut-out responding to an excessive pressure. A further safety device consists of a solenoid coil in parallel with a heating element, which when voltage across it rises in case of a heating element breakdown, trips a switch in the heating circuit. This coil is in parallel with the last heating element, seen from the water flow direction; or a solenoid coil is in parallel with each of the two last heating elements. Their magnetic fields counteract each other, so that they are magnetically balanced. When this balance is upset by one of the coils, the safety switch is tripped.
