Abstract: A general analysis system for performing an analysis used in the control of an industrial process. The general analysis system comprises a general analysis program for performing at least one analysis on a set of data and an analysis control data for controlling the analysis of the data set. According to the present invention, the general analysis program comprises a plurality of analysis primitives and the analysis control data comprises a plurality of analysis modules. An analysis may be constructed from a set of analysis modules and performed by interpreting this set using at least one of the analysis primitives.

Abstract: A building module for a ceiling having heating elements incorporated therein. The module has the form of a closed unit which can be individually mounted and removed and which comprises a frame and plates arranged on two opposite sides thereof. Heat-emitting elements are protectively arranged in the space defined by said frame and said plates and element connecting means are accessible from outside the unit and are arranged, when a unit is mounted together with other similar units to permit the elements to be connected to the intended supply source via other units located between the source and said one unit. The unit is so constructed that when mounting the same in position adjacent a similar unit there is formed a downwardly open channel between the units which channel is intended to be closed by means of a separate cover member.
