Abstract: A method and apparatus is disclosed which corrects for errors produced in data acquisition systems. Disclosed is a method and circuit for correcting errors, such as mismatch between binary weighted capacitors and offset, in a charge redistribution, weighted capacitor array analog-to-digital converter 10. A self-calibrating, self-correcting circuit 70 is comprised of a second binary array 72 of capacitors 74-84 which adds to the regular charge redistribution capacitor array 12 an error correcting signal to compensate for the mismatch. This error correcting signal is then stored and the other error correcting signals for other capacitors 50-66 in the regular capacitor array 12 are determined and subsequently stored for later correction of other capacitance mismatch.

Abstract: The extraction of Factor VIII, the antihaemophilic factor in blood, is difficult due to its instability and the presence of impurities. An initial Factor VIII containing aqueous solution such as blood plasma is purified by subjecting a FactorVIII containing aqueous migrant solution to continuous flow electrophoresis wherein flow takes place in an annular separation chamber and is stabilised by means of an angular velocity gradient; and collecting a separated Factor VIII component. 
     In order to separate the Factor VIII from albumin and fibrinogen, whilst obtaining good recoveries of FactorVIII (e.g. -60%), the migrant solution is prepared by precipitating FactorVIII from the initial solution using an organic liquid such as ethanol, and removing and redissolving the precipitate in an aqueous medium and adjusting the pH to be within the range of 7.5 to 8.6, preferably 8.3 to 8.6.

IPC: F24F13/15

Abstract: The invention relates to a ventilation blind with a number of slats which are in each case at the front end mounted in a common frame and can be operated jointly so that they are movable between an opening position and a closing position, overlapping in the closed position. If it is to lead to sealing, the overlapping must be a contact overlapping so that, on closing and when the closed blind surface is subject to wind stresses, considerable disturbing noises occur, which in view of the sheet construction are particularly irritating. Moreover, as a result of the movement play, it is not possible even in the closed position to achieve complete sealing in relation to the penetration of precipitation on the one hand and in relation to heat loss from the inside to the outside on the other hand. In order to eliminate these abovementioned disadvantages, the invention envisages that the slats are provided with sheet sections which project at the front end, on which sections a common operating rod is articulated, and that furthermore the slats are in the front region pivotable about shafts (21) which are inserted in a common bearing strip connected to the frame. The operating rod then bears a sealing rod (10) which extends in its longitudinal direction and consists in particular of rubber and which in the closed position is in contact, preferably under tension, with the bearing strip, with a leg (15) of the angled profile of the operating rod and with a cranked surface (12) of the front-side slat sheet. In cross-section, a three- point bearing for the sealing rod (10) is thus arrived at, which rod, as a result of a limited inclination and in particular of its elastic properties, ensures a completely impermeable sealing in the edge region of the slats, and, as a result of an existing closing tension, compensates the bearing clearance.

Abstract: @ Pure-green light emitting diodes comprise an n-type GaP layer (2) formed on an n-type GaP substrate (1) and a p-type GaP layer (3) formed by using a liquid phase epitaxial method, the average donor concentration of the p-type GaP layer being less than or equal to 5 x 10 16  cm -3 . Liquid phase crystal growth of the above p-type GaP layer (3) is realized by applying a method of keeping the melt used for the liquid phase crystal growth of the n-type GaP layer at a constant temperature and the ambient atmosphere at a reduced pressure for a prescribed period of time thereby to volatilize donor impurities from the melt and to compensate the donor impurities. 
     Pure-green light emitting diodes easily distinguishable from yellow-green and having high brightness can be manufactured by applying the over-compensation method which is suitable for mass production.
