Title: Balcony door safety fittings - use identical securing devices for two position door operating handle
Inventor: GROSCHKE KLAUS-DIETER
IPC: E05F7/02
Filed: 1976-04-14
Abstract: The securing device for balcony doors uses identical parts for fixing the operating handle in the locked, as well as in the open position. The operating handle is used for lifting the door leaf from its closed position slightly, before the door can be opened. For this purpose the handle is swung from its closed position downwards into an open position. In both positions the handle can be fixed by securing device working in conjunction with angle on the free leg of which the securing device is fitted rotatingly on a spindle and is resting against stop surface due to spring force. This prevents the handle snapping back into closed position, while the door is only closed while some one is outside the door on the balcony. When the door is shut and the handle in closed position, the securing device defeats any attempt to force the handle from the closed, into the open position from the outside.

Title: Concentrating solns. by cooling and crystallisation - by varying vibration frequency of cooling surfaces to suit changing concn.
Inventor: BALDUS WOLFGANG DIPL PHYS DR
IPC: B01D9/04
Filed: 1976-06-04
Abstract: The method consists of using a heat exchanger to freeze out the crystallisable constituents, the heat exchange surfaces being vibrated relative to the soln. in order to prevent the resultant "ice" from adhering to the surfaces.
