Abstract: A temperature-controlled device for switching off a heating device at a limit temperature has a thermo-mechanical temperature sensor device, a switch-off device, and manual reactivation means. The switch-off device has switching means which are activated by a trigger for switching off the heating device. The manual reactivation means have a movable handle and transmission means for transmitting a force of an operator for reactivating the switching means after switching off the heating device by the trigger. The transmission means have a click spring which at the beginning is in a basic position and, when an operating force acting on said click spring exceeds a certain limit force, clicks to a deflected position. Said click spring in the basic position enables reactivating or re-switching on, respectively, of the switching means.

Abstract: Techniques related to group determination based on multi-table dictionary codes are disclosed. In some embodiments, one or more non-transitory storage media store a sequence of instructions which, when executed by one or more computing devices, cause performance of a method. The method comprises storing a fact table and a dimension table that share a domain dictionary. The fact table and the dimension table each have a column of encoded join keys that is decodable using the shared domain dictionary. A query may specify one or more row groups for the dimension table. To efficiently process the query, one or more group identifiers are assigned to the one or more row groups. Each row group corresponds to a different group identifier. This enables a code-to-group-identifier mapping to be generated. The code-to-group-identifier mapping correlates the encoded join keys to the one or more group identifiers.
