Patent EP-0467165-A1 (EP)
Inventor: SCHUSTER GEORG DIPL-ING FH
IPC: C09K23/52
Filed: 1991-07-04
Abstract: The invention relates to aqueous solids suspensions which are stable to sedimentation and in particular milk of lime based on aqueous suspensions of calcium hydroxide Ca(OH)2, which contain, as sedimentation stabiliser, waterglass, preferably in an amount of 0.5 to 8% by weight, calculated as solid waterglass containing 17 to 20% by weight of water and based on the mass of the solid in the suspension, and processes for their preparation and their use and dry solids mixtures containing added stabilisers. In the case of the preparation of milk of lime, the waterglass may be added both before or during slaking of calcined lime and before or after calcium hydroxide is mixed into the preparation water. Suspensions stabilised according to the invention, such as milk of lime, are stable to sedimentation over a storage time of at least 5 weeks, even at low temperatures, not more than 5% of serum being formed. Even after a longer storage time without mechanical mixing, a corresponding milk of lime can be stirred up simply and rapidly for use. The invention accordingly has exceptional advantages in terms of process engineering and economics, since the investment costs for stirring or mixing apparatuses and mechanical mixing for stirring up are not required during the entire storage time. The invention leads in particular to high energy savings.

The two selective mirrors are illuminated by the primary beam and produce two secondary beams (F1, F2) of different wavelengths. In accordance with the invention, on the one hand the two selective mirrors (M1, M2) are disposed side by side and intercept different portions of the cross-section of the primary beam (FP). On the other hand, a rear face (15), which is at least partially reflecting, is disposed on the opposite side from the source (2) with respect to the selective mirrors (M1, M2).

Abstract: Procédé destiné à sauver, de manière ciblée, des cellules contre l'effet d'une cytotoxine chimiothérapique. Une cytotoxine dirigée contre des cellules malades est administrée en même temps qu'un conjugué d'antagoniste ayant pour cible des cellules normales. Le conjugué d'antagoniste est composé d'un antagoniste de la cytotoxine associée à un agent de liaison spécifique à certaines cellules qui se fixe spécifiquement sur un élément de surface cellulaire présent sur les cellules normales, mais non sur les cellules malades. L'élément de surface cellulaire est typiquement un récepteur de surface de la cellule qui participe à l'endocytose. Le conjugué d'antagoniste est spécifiquement absorbé par les cellules normales de manière à fournir une protection contre les effets toxiques de la cytotoxine. Les cellules malades qui sont exemptes du récepteur de surface n'absorbent pas des quantités efficaces d'antagoniste et sont donc sans protection.

Abstract: A toothed wheel (3) to control the gripper straps in shuttleless looms is obtained by injection molding of thermoplastic material. To increase wear resistance of the wheel toothing (1), a strip (2) of thermosetting material - reinforced with carbon or cotton fibres - is introduced into the mold during the molding operation, said strip (2) having a fretted section reproducing the final profile of said toothing (1). The strip (2) is pre-manufactured in a flat position and of length sufficient to cover the full circumference of the toothed wheel (3). It then remains firmly positioned into the mold, once it has been elastically deformed into a circle to be introduced therein. This also allows to considerably accelerate the toothed wheel manufacturing process.

Abstract: A doughnut making machine and apparatus has a hopper for the dough of a type which exudes gluten or other sticky substances when compressed, the hopper terminates in a lower cylinder which co-acts with the cutting surfaces on a lower cutting piston. An extruding piston pushes the dough out between the cutting edge of the cylinder and the cutting piston and, thereafter, with retraction of the cutting piston, the dough is severed into a conventional toroidal shape. Edible release oil is distributed onto the cutting edges of the piston and the cutting edge of the cylinder by various distribution techniques. The method by which doughnuts are extruded in a generally toroidal shape while distributing a film of edible release oil onto the dough cutting surfaces and then severing the formed toroidal shaped doughnut from the cutting surfaces whereby the doughnut contacts the release oil on the dough cutting surface and freely releases from the cylinder's cutting edge.

Abstract: A method and system (10) for detecting blood pressure pulses and screening out artifact-induced pulses when an automatic blood pressure monitor is provided. In preferred embodiments, the system detects the occurrence of an oscillometric pulse, determines the amplitude and rise time of the pulse, determines whether the amplitude and rise-times are within patient-specific screening limits and disregards pulses not within the limits, determines whether a pulse matches other pulses and saves the matching pulse data, determines the diastolic and systolic pressure based on the saved matched pulse data, and updates the patient-specific screening limits. In a preferred embodiment, pulses are matched based on similar amplitude and rise time characteristics. The amplitude and rise time screening limits are updated based on average values of prior blood pressure measurements for the patient.

Abstract: 2.1. The chemical synthesis of amino acids produces a racemic mixture which can usually be fractionated by enzymatic cleavage. The remaining unwanted enantiomer is subsequently racemised anew and subjected again to racemate resolution. In the case of amino acids, this racemisation can easily be achieved in a temperature/time programme, but in the case of hydantoins the racemisation takes place in an acceptable time only for 5-arylhydantoins. The intention is therefore to provide a racemisation process for hydantoins which should be possible to carry out as simply as possible, i.e. without problematic foreign ions such as copper or additional compounds. 2.2. In the novel racemisation process, the enantiomer of a hydantoin which is monosubstituted in the 5 position is reacted in the presence of an ion exchanger. Anion exchangers are preferred, at a pH between 6.0 and 13.5. 2.3. Preparation of enantiomeric pure amino acids by enzymatic hydrolysis from 5-monosubstituted hydantoins.

Abstract: A fully supported membrane assembly (40) for an electrochemical fuel cell is provided. A first and second layer of porous electrically conductive sheet material (44,50), such as carbon fiber paper, has a solid polymer ion exchange membrane (43) interposed therebetween. The layers of sheet material cover and support the membrane over substantially its entire surface area. The layers of sheet material are coated with a catalyst (54) to tender them electrochemically active. The layers of sheet material and the membrane are bonded together to form a consolidated assembly. Openings (112,111,113) are formed in the layers of sheet material and the membrane to accommodate the passage of fluids through the assembly. Seals are formed by impregnating the layers of sheet material with a sealant material which generally circumscribes the fluid passage openings and the electrochemically active portion of the assembly. Alternatively, grooves are formed in the surfaces of the electrodes facing away from the membrane, and sealant material is deposited into the grooves. The grooves generally circumscribe the fluid passage openings and the electrochemically active portion of the assembly.
