Abstract: A system for producing impact copolymer polypropylene (such as propylene-ethylene copolymer) from propylene and other alpha-olefins (such as ethylene) provides two or more reactors in series wherein at least one downstream reactor includes a system for controlling the composition of the copolymer produced and a system for controlling the fraction of the total product which is produced in the downstream reaction system. The composition of the copolymer produced in the downstream reaction system and the proportion of the total polymer produced in that reaction system are calculated. The calculated values are compared to target set points. Adjustments to the alpha-olefin partial pressures are made when the calculated values do not match the target values. An adjustment scheme, preferably under computer control, is provided for decoupling the interaction of the partial pressures on copolymer composition and production rate.

Abstract: Methods for depositing films comprising a mixture of rare earth, alkaline earth and copper oxides on a substrate comprise forming a metallo-organic complex of each of a rare earth metal, an alkaline earth metal and copper. Each of the metallo-organic complexes has a vaporization temperature below the temperatures at which the metallo-organic complexes rapidly thermally decompose, oxidize or hydrolyze. A vaporized mixture of the metallo-organic complexes is formed and the vapors are contacted with the substrate. Deposition of the film is then induced from the vapors onto the substrate.

Abstract: The transport apparatus comprises an endless guide device extending in a closed path and at which there are guided a number of entrainment elements. These entrainment elements are interconnected by a toothed belt deformed into a substantially wave-shaped configuration by attachment elements secured at the entrainment elements. At each of the starting region and terminal region of the conveying-active path of the transport apparatus, there are rotatably mounted two parallel cam discs rotatable in a predetermined direction of rotation by related drives. Recesses in the cam discs act upon the entrainment elements such that the latter are driven at the starting region and terminal region of the conveying-active path and are dispositioned in a predetermined mutual position. The spacing between the entrainment elements at the conveying-active path and at the non-conveying active path is compensated by the resilient action of the wave-shaped deformed toothed belt. Differences in the operating cadence or in the phase position between printed products delivered to the transport apparatus and outfed away therefrom are compensated by increasing or reducing the spacing between the entrainment elements.

Abstract: The circuit uses a switch (2) inserted in series with the motor (1) allowing the latter to be supplied with a succession of current pulses. The back EMF during interruption of the motor current is detected for comparison with a reference value representing the required motor rotation and an output signal is supplied to a motor control stage. The motor current and voltage are controlled independently via a pair of pulse width modulators (13,14). The first modulator (13) ensures pulse pauses sufficient for measurement of the back EMF and the second modulator (14) exhibits a frequency above the audible frequency range, with the pulse pauses sufficiently short to prevent the motor current dropping below the network value.

Abstract: Apparatus for investigating e.g. primary hemostasis comprises a feed chamber (2) and a reaction chamber (39) with a flow channel, where blood is fed through the channel by a piston and cylinder unit (1) and a pressure sensor (9) measures variations in pressure in a blood-free pressure measuring chamber (3), which are dependent on the reactions taking place in the reaction chamber. Apparatus for investigating global, especially primary hemostasis in whole blood or platelet-enriched plasma comprises a feed chamber (2) and a reaction chamber (39) with a flow channel for the blood. The blood is fed through this by a piston and cylinder unit (1). A pressure sensor (9) measures variations in pressure in a blood-free pressure measuring chamber (3), which are dependent on the reactions taking place in the reaction chamber. Blood which has passed through the reaction chamber is then fed to a collecting vessel. The pressure measuring chamber is positioned below the feed chamber and above the surface of the blood passing through the reaction chamber into the collecting vessel. An independent claim is also included for a method for investigating global, especially primary hemostasis in whole blood or platelet-enriched plasma in which blood is fed from a feed chamber through an orifice into a reaction chamber under predetermined shear or flow conditions. It is then fed on to a reaction surface where coagulation takes place (e.g. clot formation under the influence of thrombin), forming a structure composed of polymerized fibrin and cellular components (thrombocytes, erythrocytes and leukocytes) or a force is developed which is exerted by activated thrombocytes on the fibrin network in the reaction orifice. The alteration in pressure due to this is then measured. The shear rate, shear force or flow rate is then adjusted, depending on the measured pressure or blood viscosity calculated from it, to conform to a predetermined value.

Abstract: Optically active tetrahydrofuran-2-carboxylic acid esters containing a mesogenic molecular building block are suitable as dopes in liquid-crystal mixtures. They result in liquid-crystalline ferroelectric phases having short switching times and in electroclinic phases having high electroclinic coefficients. A further advantage is that they induce a helix of very low pitch, so they are also suitable for helix compensation in LC mixtures. The compounds are symbolised by the general formula <IMAGE> in which the symbols and indices essentially have the following meanings: R<1> = alkyl/alkenyl or tetrahydrofurancarbonyloxy or -thio; j, l and n = zero, 1 or 2; k and m = zero or 1; -A<1>, -A<2> and -A<3> = phenylene, cycloalkylene or corresponding N-, O- or S-containing heterocycles; -M<1> and -M<2> = bridges, such as -CO-O-, -OCH2- or -CH=CH-; and X = O or S.
