Patent DE-3261774-D1 (DE)
Title: Process for making allylic esters of tetrabromophthalic acid
Inventor: FINLEY JOSEPH HOWARD
IPC: C07C69/83
Filed: 1982-09-17
Granted: 1985-02-14
Abstract: Allylic esters of tetrabromophthalic acid are formed using allylic alcohol both as a reactant and a solvent. In the first step, the alcohol and a base are reacted with tetrabromophthalic anhydride to form the half-ester sodium salt. In the second step, the half-ester sodium salt is reacted with allylic halide to form the diester which crystallizes from solution. The excess solvent may be treated to recover the raw materials or recycled.

Title: Blood fractionation improvement
Inventor: MATTOCK PATRICK
IPC: B01D57/02
Filed: 1982-03-25
Granted: 1989-01-26
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.

Abstract: An inclination sensor is disclosed which includes a capsule 15 containing a conductive liquid 17 which forms a liquid pendulum and having first and second resistive tracks 11, 13. In a first measuring configuration the terminals A, B of track 11 are connected to positive and negative voltages respectively and the terminals C, D of resistive track 13 are connected together, to form a sensing electrode. The voltage at terminal B is then adjusted so that the voltage at common electrode C, D, sensed through the conductive liquid 17 is adjusted to be zero. The ratio of voltages at terminals A and B is then related to the position of the conductive liquid 17 relative to the resistive track 11 and thus of the inclination of the capsule relative to horizontal. In an alternative measuring configuration, the roles of the resistive tracks 11, 13 are reversed, to allow the sensor to measure angles in a different angular range.
