Title: Key and rotary locking cylinder for a safety lock
Inventor: KELLER ERNST
IPC: E05B27/04
Filed: 1994-03-02
Abstract: A key and rotary cylinder for a safety lock are disclosed. The key has in its shank a continuous bore hole in which two opposite control elements are supported. These control elements are movable inwardly against the restoring force of a pressure spring arranged in the bore hole. An additional tumbler is lifted by a control element when the key is inserted into a key slot of the rotary locking cylinder. This additional tumbler engages in a recess of the stator When using a key without a control element, the rotor is blocked by means of the tumbler. When using a key according to the invention, the rotor can be turned and the tumbler is lifted out of the recess and the control element is moved inward radially. After turning by 90°, for example, a counterpin of the stator is brought into line by the tumbler. In the absence of a control element, the rotor is blocked by the counterpin in this case as well.

Title: Foundry sand regenerating process and device
Inventor: BOENISCH DIETMAR
IPC: B22C5/10
Filed: 1993-02-17
Abstract: (57) Abstract A regeneration process for foundry sand, in particular active bentonite-containing used sand, dispenses with preliminary thermal treatments and al-lows most valuable substances contained in the used sand to be recovered. The sand is partially fluidized with air in a grinder, by means of which valuable sub-stances and dust are continuously carried out and separately collected. The con-siderably increased grinding and dedusting performance requirements caused by the suppression of preliminary thermal treatments are met by a composite system of separate grinding and dedusting areas through which the sand contin-uously circulates in a vertical circuit.

Patent CA-2134033-A1 (CA)
Title: Device for opening and closing a window, a door, or the like
Inventor: EIKMEIER WERNER
IPC: E05F11/16
Filed: 1994-10-21
Abstract: In a device for opening and closing a window, a casement is moved between a closed and open position with respect to a stationary frame. This is done by means of a longitudinally displaceable toothed rack, which transfers the longitudinal movement into a movement of the casement by means of a hinge rod. In order to obtain a device which is easy to operate, it is proposed that in addition to the first toothed rack co-operating with the casement, a second toothed rack is provided in the frame which changes closing elements located on the frame between a latched position holding the casement and an unlatched position releasing the casement, by means of a closing rod. Although both toothed racks are longitudinally displaced by the same actuating means, as a rule only one of the two toothed racks is coupled to the actuating means while the other is uncoupled and stationary. The currently coupled toothed rack uncouples itself automatically after a specific distance of travel and the final phase of its longitudinal displacement is used to couple the othertoothed rack to the actuating means.
