Abstract: Flooring panel or wall panel and a use thereof in a wet room. The panel is provided with a locking means in the form of groove (6) and tongue (7) forming a tongue/groove joint for assembling of the panels. The groove (6) and the tongue (7) are made of water tight material and formed with a snap-together joint.

Abstract: A building panel, such as a flooring panel or wall panel and a method of assembling the same into a floor, wall cladding, etc. The panel is provided with a locking means in the form of groove (6) and tongue (7) forming a tongue/groove joint for assembling of the panels. In a preferred embodiment, the groove (6) and the tongue (7) are made of water resistant material and formed with a snap-together joint.

Abstract: Method of machining a thermosetting laminate (13) by means of an apparatus comprising at least one high-frequency or ultrasonic oscillation generator (1) and at least one dimension changing or adjusting unit (4) having at least one piezoelectric crystal (8) performing a linear vibration when charged with an alternating current. The linear vibration is propagated through at least one mechanical or electronic amplitude transforming unit (5), whereby generated high-frequency or ultra-sound amplitude is transformed into a linear vibration. The linear vibration is during machining propagated via at least one tiller or tool holder (7), being connected to the amplitude changing unit (5), to at least one tool (2) attached to the tiller or tool holder (7) and consisting of a least one diamond (3), whereby at least said tool (2) performs a linear vibrating movement (16) and whereby said tool (2) executes said machining.

Abstract: A device for heating boilers (1) in heating plants comprises a means (2) for heating a heat carrying medium present in the boiler and circulating out thereof in the heating plant as well as a means (11) adapted to detect the temperature of the heat carrying medium present in the boiler and send signals to the heating means (2) to start and stop the heating of the medium when a first lower temperature level is underpassed and a second higher temperature level is exceeded, respectively, by the medium in the heating boiler (1). The device comprises further means (12) adapted to delay the start of the heating means (2) when the first temperature level is reached by the medium and this is detected by the detecting means (11).
