Granted: 1988-06-27
Abstract: An arrangement for fastening uprights 3 on building structures has a base plate 1 which, with the interposition of a sealing plate 11, butts against the outside of the building structure. The base plate 1 is fastened via fastening bolts 10, which pass through holes 6 in the base plate and holes 12 in the sealing plate and can be fixed in tubes 14 of an insert part 13 anchored in the building structure. Disc-like filler elements 7 with a longitudinal slot 8 are inserted in the holes 6 of the base plate 1, with the result that, by virtue of these filler elements being rotated, it is possible to change the position of the base plate 1 in relation to the position of the tubes 14 anchored in the building structure. The base plate 1 is connected to a guide part 2 which encloses the upright 3. The upright 3 is secured in the guide part via fastening bolts 22, which are fixed in a square sleeve inserted into a square hole 20 in the upright 3. The fastening bolts 22 pass through a slot 23 in a wall of the guide part 2, which makes it possible to establish the position of the upright 3. <IMAGE>

Abstract: A push-in easy opening closure for a can end (1) or similar container member formed with a resealable pressure releasing tab (4) closing an opening (5) in the can end (1) and integrally connected to the can end (1) at integral connection (6). The tab (4) is adapted to be bent about the integral connection (6) during the opening operation, and to avoid sheet metal fracture at the integral connection (6), the radius about which the tab (4) will bend in the region of the connection (6) is artificially increased by some convenient means. In a first embodiment (FIGS. 1 to 3), a raised dimple (7) is formed centrally of the integral connection (6). In another embodiment (FIG. 4), an elongate raised bead (8) is formed longitudinally of the anticipated line of bending of the connection (6). In a still further embodiment (FIGS. 5 to 7), an elongate raised bead (9) extends transversely of the anticipated line of bending of the connection (6) and to either side of said line. In a still further embodiment (FIG. 9), an abutment (11) is secured or formed on the inner face of the can end (1) adjacent to the anticipated line of bending about the connection (6). In each of the embodiments, the bending radius of the tab (4) about the connection (6) is substantially increased to effectively prevent fracture of the tab (4) occurring.

Abstract: Green coffee is decaffeinated in at least three extraction sections in continuous or semi-continuous countercurrency to an extraction liquid containing water and methyl ethyl ketone or methyl acetate, at a temperature approximately equal to the boiling temperature of the solvent. The coffee is supplied to the first extraction section section with approximately its natural water content, and the organic solvent is supplied to the last extraction section with a water content of 5 - 10 % by volume. Water is added to the first extraction section in at most such a quantity that no segregation occurs, and the solvent enriched with caffeine, withdrawn from the first section, contains 5 - 10 % by volume of water. The residence times of the coffee and the extraction liquid in the extraction apparatus, the phase ration between the extracted coffee and the extraction liquid and the number of extraction sections are attuned to each other in such a manner that the caffeine content of the extracted coffee is less than a pe-determined percentage, preferably less than 0.1 %, calculated on its dry content.

Filed: 1986-08-14
Abstract: The device consists of an inlet section (2), a centre section (3) and an outlet section (4) each with internal apertures (5, 9, 13), which together form a passage for a fish net (23). The inlet section (2) has a cone-shaped surface (6), which draws the net (23) together and the inlet section is separated from the centre section (3), thereby forming an outlet opening (8) for water. One end of the aperture (9) adjoins a cone-shaped surface (10) and the other a cone- shaped surface (11). In the outlet section (4) two sets of opposing nozzles (18) are arranged in planes at right angles to one another with their jets aimed in the direction of the aperture (9) in such a way that the combined jet can flow freely past the surface (11), through the fish net (13) in the aperture (9), past the surface (10) and out through the opening (8). The net is compressed by the jets of water and held suspended so that the through-flow resistance is minimal. This results in intensive mixing of water and air with maximum cleaning effect. <IMAGE>

Abstract: Method for leak detection in a pipeline system, more particularly in a water supply and sewer system. The purpose of the invention is to efficiently and with great accuracy determine the scope and location of damages in the line system. For this purpose leakage indicating means are employed that comprise tracers, which are supplied to the water running through the pipes, each pipe being supplied a special tracer. Samples are taken at certain points downstream in the system. These samples are analysed and the concentration of tracers is determined. Using the concentration figures, the inflow of tracers from adjacent pipes can be established, in respective pipes. Thus, an estimation of the leakage from and to each pipe can be made.

Abstract: The disclosure concerns self-supporting ceramic structures, including ceramic composite structures embedding a filler, and methods of making them. The ceramic structures comprise a polycrystlline material made by oxidation of a body of molten parent metal with an oxidant. The polycrystalline material has a first region substrate surmounted by a terminal region stratum which is integral with the first region. The terminal region stratum which is harder and of denser, finer crystalline structure than the first region substrate and is formed in a reaction stage subsequent to the reaction stage in which the first region of polycrystalline material is formed. Growth of the first stage is attained by by attenuating or interrupting the transport of molten parent metal to the first region under conditions which nonetheless leave or maintain therein enough oxidizable molten parent metal to form the polycrystalline material of the terminal region.
