Abstract: There is disclosed a method of producing a Factor VIII (AHF) containing fraction having a specific activity of at least 2.5 units of Factor VIII/mg protein as well as a portion of immunoglobulin G (IgG) of 10 mg/1000 units of Factor VIII at the most. Its risk of transmission of viral or bacterial infections is to be avoided or largely reduced. The method consists in that undesired proteins are at first precipitated from a Factor VIII (AHF) containing plasma fraction in the presence of SPS. The purified Factor VIII containing solution is treated with suitable salts or salt mixtures in order to obtain a Factor VIII containing precipitate. This precipitate is dissolved, lyophilized and finally heat-treated.

Said material strip is preferably made integrally with the bottom tab (72), which is attached to the front peripheral wall (4), of the bottom, which is constructed as a foldable bonded bottom, and is connected to said bottom tab via a tear-off edge (78). The material strip (38) is then folded, together with the bottom tab (72), in an automatic folding stage onto the inside of the blank and bonded in its position. When the dispenser box is set up from the flat-folded state into the box shape, the bottom tab (72) lifts up from the peripheral wall (4), thus tearing off the tear-off edge (78). <IMAGE>

Abstract: In addition to the fire characteristic of smoke density (MWR), the environmental characteristic of relative air humidity (F) is measured in the scattered-light detector using a humidity sensor (FS) arranged in the measuring chamber (MK). A humidity measured value (MWF) is determined from the measured relative air humidity (F) by means of a measured value linearisation device, the smoke density measured value (MWR) being compensated by the humidity measured value (MWF) above a specific measured value for the relative air humidity (F). The compensated smoke density measured value (KMWR) is processed further in order to form alarm criteria. In this case, the compensation can be performed in the scattered-light detector (SM) or in the control centre (Z), the compensated smoke density measured values (KMWR) or the smoke density measured values (MWR) and the humidity measured values (MWF) being transmitted periodically to the control centre (Z). <IMAGE>

This polymer may be a homopolymer, a mixture of homopolymers, a copolymer of alkyl vinyl ethers of different alkyl chain length, a copolymer of one or more alkyl vinyl ethers with one or more copolymerisable monomers or a mixture of such copolymers. Typical copolymers are copolymers of alkyl vinyl ethers with alkyl acrylates, alkyl methacrylates, olefins, dialkyl fumarates or maleates, eg copolymers of n-butyl vinyl ether with di(n-tetradecyl) fumarate. Other polymers are copolymers of an alkyl vinyl ether with an ethylenically unsaturated carboxylic acid or anhydride, subsequently reacted with an alcohol or an amine or both, eg a copolymer of methyl vinyl ether and maleic anhydride reacted with n-tetradecanol, n-hexadecanol or a mixture of these alcohols.

Abstract: A method and apparatus are disclosed for aligning a plurality of multi-processors (10). The apparatus preferably comprises an alignment unit (20) associated with each processor and a logic network (30) for combining the output of the alignment unit and for broadcasting information to these units. Alignment is achieved by inserting in the instruction stream of each processor that is to be aligned a request for alignment, by testing for prior completion of any instructions that must be completed and by causing all processors to wait until they have all made the request for alignment and completed necessary prior instructions. The alignment unit associated with each processor monitors the instruction stream to detect a request for alignment. When all the units have made such a request, the logic network informs the alignment units; and the alignment units inform the processors.
