Granted: 1990-01-17
Abstract: The flange-like lid rim of a packaging container, including the outwardly projecting gripping part shaped thereon, is laterally enclosed by an all-round rim portion, so that it is not accessible for opening the packaging container. The actuation of the gripping part leads to the separation of a rim extension of the container body engaging below the gripping part and to which the latter is non-detachably connected by a pushbutton connection. The sealing fixing of the lid to the container body takes place by interlocking engagement beads. The packaging container avoids any hot sealing joint as a guarantee seal and is made from completely burnable plastic.

IPC: B23K35/28
Filed: 1987-09-24
Granted: 1992-01-22
Abstract: Problems are caused by stress corrosion cracking and exfoliation cracking in the heat-affected zones adjacent welds in structure of welded components formed of Al alloys, particularly of the 7000 series but also of the 5000 series. The invention seeks to overcome these by the use of Al-Mg welding wire containing 0.01-0.5% Ga and/or In and/or Sn, the composition being chosen such that the weld bead has a potential at least as electronegative as the components and preferably in the range -1200 to -1300 mV with reference to a standard calomel electrode. To prevent diffusion of Ga/In/Sn, the components may be pre-coated eg by using a double-pass welding technique.

Granted: 1996-03-06
Abstract: A method is provided for multiplying the number of copies of a target polynucleotide sequence comprising a series of primer hybridization, extending, and denaturing steps to provide an intermediate double-stranded DNA molecule containing a promoter sequence (through the use of a promoter-sequence-containing primer) incorporated upstream from the target sequence. The double-stranded DNA intermediate is then used to grow multiple RNA copies of the target sequence. The resulting RNA copies can be used as target sequences to produce further copies. Multiple cycles of this sort can thereby exponentially increase the number of target sequence copies.

Abstract: A method of burning solid fuel having low melting point alkaline compositions, such as alkali metal salts, particularly lignite and salty brown coal. The fuel is introduced into the reaction chamber of a circulating fluidized bed reactor, and is mixed prior to introduction to the reaction chamber with a reactant material capable of reacting with the low melting point alkaline compositions of the fuel to produce high melting point alkali metal compounds during combustion. The temperature in the reaction chamber is kept below the melting point of the formed alkali metal compounds. The reactant material comprises silica oxide or a metal oxide, or hydroxide, of the group consisting of aluminum, calcium, magnesium, iron, titanium, and mixtures of two or more thereof. Kaolin is particularly effective, especially when the molar ratio of Al/(Na and K) is at least 1.0.

Abstract: A device is disclosed for scanning a record carrier (1) provided with substantially parallel tracks, which device comprises a closed-loop position control system with position and velocity feedback for controlling the scanning point (P) towards the centre of a specific track. For this purpose the position control system comprises a positioning system (15) for moving the scanning point in a direction transverse to the tracks, a measuring system (4, 6, 9, 10, 11, 12, 13) for generating a velocity signal (RS) which is indicative of the velocity with which the scanning point (P) is moved across the tracks, and for generating a first error signal (RE) whose magnitude, within a predetermined limited range to either side of said specific track, is proportional to the deviation between track centre and the scanning point (P). The position control system further comprises a control circuit (3) for controlling the positioning system depending on the first error signal (RE) and the velocity signal (RS). The control circuit (3) comprises means for generating at least one substitute error signal (PE min , UC min ) which within a second range, outside the first range, has a sign which is indicative of the direction of the deviation, the control circuit (3) being adapted to control the positioning system (15) in response to the first error signal (RE) or a substitute error signal (UC min , PE min ) depending on whether the deviation is situated in the first range or the second range respectively, in such a way that the error signal employed for position feedback depends on the magnitude of the deviation, and the velocity signal (RS) used for velocity feedback is independent of the magnitude of the deviation.
