Abstract: The invention relates to a collapsible smoking box for smoking meat and fish in particular. The physical size of known smoking boxes is fixed and, accordingly, does not depend on the quantity of the products contained in the box to be smoked therein. Quite a large empty space of no use may be thus formed in the smoking space. In order to solve this problem, the smoking box according to the invention is formed by a plurality of separate modules to be piled up on upon another, which modules are equal in structure with the exception of the bottom of the lowest module.

Abstract: The present invention concerns a control and measuring system for flat-individual heating/cooling, meant to serve the purposes of charging for the total heating/cooling energy consumption individually per flat, said system comprising as components known in themselves in prior art: room thermostats, which govern the valves of heating radiators or cooling evaporators, the thermostats and valves presenting an on/off design, and measuring pick-ups for the heating/cooling fluid temperature on the outgoing and return sides, and a connecting unit for transfer of the measurement data to a central unit, which is responsible for data processing and output.
