    摘要: This disclosure is concerned with flame retarded polyethylene terephthalate compositions which have enhanced drip suppression due to the incorporation of a two-phase polyacrylate comprised of a cross-linked elastomeric first phase to which a rigid thermoplastic second phase has been grafted. These compositions have enhanced crystallization velocities and therefore may be molded into colder molds and with shorter mold cycles than has been conventional for polyethylene terephthalate compositions.

    摘要: Polyalkylene terephthalates containing 0.5-30% by weight of oligomeric carboxylic acid polyesters have a higher crystallization speed and thus allow lower mold temperatures and shorter injection cycles. The polyalkylene terephthalates generally have intrinsic viscosities in excess of about 0.4 dl/g in 1:1 phenol tetrachloroethane at 25.degree. C. and are at least about 90 mol % terephthalic acid based. The oligomer additive is based on carboxylic acids, with sebacic and adipic being preferred, and aliphatic, cycloaliphatic or araliphatic dihydric alcohols. This additive has a minimum polymerization degree of 2 and a maximum number-average molecular weight of about 6000.Faster crystallization rates can be imparted to polyalkylene terephthalates by mixing them with the ester additive and melt homogenizing the mixture.

    摘要: The present invention is concerned with polyalkylene terephthalate molding compositions which have improved crystallization behavior as a result of blending with selected sulphonic acid esters. The addition of an effective amount of these esters, generally between about 0.5 to 30 wt. %, improves the rate of crystallization of polyalkylene terephthalates such as polyethylene terephthalate thus permitting the use of shorter mold residence and lower mold temperatures in injection molding.The invention is also concerned with a process for improving the crystallization behavior of polyalkylene terephthalates by melt blending them with selected sulphonic acid esters.

    摘要: An arrangement for motorized assistance in movement of manually movable components of medical apparatuses is provided. The arrangement includes at least one torque sensor that is arranged in a drivetrain of a movable component of a medical apparatus. The at least one torque sensor detects the moments occurring in the drivetrain in a stationary state and in motion. Using an evaluation unit, the torque detected by the at least one torque sensor may be compared against a predefinable first threshold value. The first threshold value is predefined according to a possible position of the movable component. The arrangement includes a drive unit, by which the drive of the drivetrain may be provided with motorized assistance when the first threshold value is exceeded.
