Abstract: The present invention relates to a control system for controlling, accelerating and distributing of competence development. The system comprises at least one first memory device operable to store assessments and self-assessments for validation and education material. The control system also comprises a coach module operable to administrate course packages, learning pieces, assessments and study plans. The control system further comprises an individual module for each individual, wherein each individual module is operable to store individual-adapted course plans. The control system also comprises an individual validation module for each individual, wherein each individual validation module is operable to store results of the individual competence development. An archive module is operable to create and deliver statistics. The control system further comprises at least one control means operable to control who should have access to the content of the first memory device, the coach module, and the archive module.

Abstract: The present invention relates to a control system (10) for achieving quality ensured competence development. The control system (10) is connected to a distributed computer network (12). The control system (10) includes a first memory device (14) which is connected to the distributed computer network (12) and which is operable in storing all course sections for different courses and an ideal time for each course section. The control system (10) also includes a second memory device (16) which is connected to the distributed computer network (12) and which is operable in storing all study material affiliated with said course sections. The control system (10) also includes a third memory device (18) which is connected to the distributor computer network (12) and operable in storing individual-adapted course plans.

Abstract: An air conditioning unit comprises a housing (1) which consists of a bottom (2), a roof (3), two side walls (4, 4'), a rear wall (5), and a front wall (6) having an opening (8) which is closeable by means of at least one door (7, 7') and which permits access to the interior of the housing; means for introducing supply air into the housing; and means for evacuating exhaust air therefrom. Two vertical air ducts (13, 13') provided adjacent to the front wall (6) have a large number of small holes (14) through which supply air can be introduced into the housing in the form of partial currents which are directed away from the front wall (6) towards the rear wall (5), both when the door (7, 7') is closed and when it is open.

Abstract: An arrangement for mounting a tube (4) provided with a flange in a hole (3) formed in a wall (2) comprises a locking ring (8) with at least three peripherally spaced apart seats (10) adapted to cooperate with a corresponding number of pins (9) which are fixed to the wall and which each have an oblique surface against which a cam surface (13) provided adjacent to the seat (10) on the periphery of the locking ring is arranged to be applied so that, when the locking ring is turned, the locking ring is urged against the wall in order to compress an elastic sealing ring (7) provided between the locking ring and the wall.

Abstract: A filter comprises a filtering wall (2) which has a front face and a rear face and which is normally permeated by a medium in a direction from the front face towards the rear face such that the pollutants entrained by the medium are separated at the front face of the filtering wall and the purified medium is allowed to pass through the wall and into a space behind the filtering wall, the flow of medium through said wall being reversible, if so desired, in order to remove said separated pollutants from the front face of the filtering wall so as to clean said wall. According to the invention, the front face of the filtering wall is provided with one or more elastic cover elements (9) which are movable relative to the filtering wall and adapted upon reversal of the flow of medium, by elastic deformation under the action of said flow, to be removed wholly or partly from the wall while working said separated, adhering pollutants in order to facilitate the removal thereof.

Abstract: A filter device for purifying air or gas comprises at least one filter layer (2) which is hit and permeated by a gas flow passing through the filter device, so as to separate contaminated constituents from said gas flow. In the immediate vicinity of the front surface of the filter layer (2) that is initially hit by the advancing gas, there are mounted a plurality of flexible strips (8) of a fibrous or non-woven material which are movable with respect to said surface and adapted automatically to be set in motion by the advancing gas in order to whip or otherwise mechanically work said filter layer (2) to counteract premature clogging thereof, and adapted themselves to intercept and separate contaminated constituents from the gas flow so as to prefilter the gas flow before it reaches the filter layer (2).

Abstract: A dust collector including two tubes which communicate through an interconnecting conduit. A first tube operates as a cyclone which separates a great fraction of dust or solid components from the incoming air and collects the same in a bag at the bottom of the tube. The second tube includes a filter unit composed of a coarser filter as well as a surrounding fine filter, the filter unit receiving the pre-purified air from the cyclone tube through the interconnecting conduit and separating the remaining dust particles therefrom.
