Patent SE-508762-C2 (SE)
Inventor: JENSEN OVE OESTERGAARD
IPC: E04F19/04
Filed: 1993-03-31
Abstract: In building rooms it is quite customary that in the transition between the walls and the ceiling there are mounted so-called ceiling lists, which are normally spiked to the walls or to the ceiling. When later on a painting or wallpapering work is made it is difficult to remove and remount these ceiling lists, such that the painter or paperhanger will have to carry out a minute stop of the working towards the ceiling list, which accounts for a really considerable increase of the costs of the artisan's work. In connection with the invention it is realized that the ceiling lists, just as certain already known foot lists, may well be designed with a narrow, rigidly mounted support portion, preferably constituted by mutually separated mounting profile elements, adapted to lockingly receive a removable, clipped-on and broader cover list element. Thus, the latter list element will be easy to both remove and remount, and it will then be unimportant whether the painting or wallpaper hanging is not terminated particularly accurately along the ceiling corner. In connection with the invention it is also recognized that the ceiling list, when made hollow, is advantageously usable for a concealed trunking of conductors for highly placed sensors e.g. fire detectors or remote control units.

Abstract: A method for extracting from gases of combustion and flue gases which have boiling points beneath -160 DEG C at least one contaminating other gas which has a boiling point within the range -140 to 25 DEG C. The combustion gas and the flue gas are cooled with the aid of at least one gas stream in a cryogenerator which functions in accordance with an expansion process. The gas stream has a temperature which is sufficiently low to condense the contaminating gas. The contaminating gas is then collected for possible further treatment. An arrangement for carrying out the method includes an air-seperation apparatus and at least one heat-exchanger (160A or 160B) for cooling the combustion gas and the flue gas in the apparatus with the aid of cold gas flows. The arrangement also includes a conduit (165) for delivering combustion gas and flue gas to the heat-exchanger or exchangers (160A, 160B), cooling gas delivery conductors (140, 170), a conductor (180) for discharging purified gas, and a conductor (185) for discharging condensed contaminated gases.

Title: Water purificn. plant for removing iron and manganese
Inventor: NILSSON BROR
IPC: E03B1/04
Filed: 1996-06-26
Abstract: A water treatment plant comprises a treatment tank (1) at atmospheric pressure to which raw water is supplied by a first pump (7). A mixture of air and the raw water is fed to the upper part of the tank to flow downwards through a filter (13) into a collecting magazine (15). A pressure tank (17) is connected to the magazine (15), and the appts. also includes a filter-washing mechanism (22,23,30,31). A second pressure-controlled pump (18) feeds filtered water from the magazine (15) to the pressure tank. The filter-washing mechanism includes an evacuating device above the filter. It consists of a syphon (30) whose suction end is placed between a lowest level in the tank for activating the first pump, and a highest level in the tank for deactivating the pump. It also includes an overflow (31) whose opening is above the highest level in the tank. A control system (24) keeps the second pump deactivated for long intervals or for short periods when a connecting line (22) between the pressure tank (17) and magazine (15) is opened. Clean water is fed from the tank (17) and the magazine (15) up through the filter (13) to raise the level in the tank to the overflow. This enables precipitates in the tank to be discharged through the syphon and overflow.

Abstract: The combined tyre and wheel system has a rim(2) with a rounded lip(6) on both sides and each rim lip has a tubular hollow chamber(12) with a rectangular or square cross-section and an annular opening(8) into which the bead area of a special tyre is inserted. Remaining space(16) in the tubular hollow chamber(12) is filled with a liquid fluid material. In a design variation the tyre has a hollow bead area into which, after location of the tyre bead in the tubular chamber of the rim, a curable liquid material is injected to expand the bead until it fills the chamber. Assembly of the tyre and rim involves rotating the tyre bead(14) in the longitudinal direction and inserting through the annular opening(8) into the hollow chamber(12) where, due to the elasticity, it recovers to its original position. Any remaining space(16) in the hollow chamber(12) is then filled with a curable liquid material either via a hole(20) or through the annular joint(8). The bead(14) position is then adjusted to optimise roundness before the liquid sets. A bead area with an internal hollow chamber can be expanded with a curable fluid until the bead completely fills the tubular chamber(12).
