Abstract: The pyrrolidinium sulphobetaines, which have a carboxamide group as additional polar structural element and the formula I <IMAGE> in which R1 to R4 are hydrogen or alkyl radicals and n is 0 to 3 are prepared by reacting alkyldiallylamines, halocarboxylic esters, amines and bisulphites in various orders. The intermediates do not need to be isolated. The reactions are technically simple to carry out and give high yields. Sulphobetaines containing carboxamide groups can be used as conductive coating materials. Representatives of this class of compounds substituted by long chains have valuable surfactant properties which enable them to be used as components in detergents and cleansers, as flotation agents or as emulsifiers.

Abstract: A racket for playing a game using a ball of limited resiliency such as a tennis racket comprises a racket head frame portion provided with stringing, a handle, and a shaft arrangement connecting the racket head frame portion and the handle. The resonance frequency of the racket head frame portion at least approximately corresponds to the period of time for which a ball is in contact with the strings of the racket when struck thereby, and the natural frequency of the racket substantially corresponds to the excitation frequency of the ball. The thickness of the racket frame as measured in a direction normal to the plane of the stringing is greater than the thickness of the handle as measured in a corresponding direction.

Abstract: Disclosed are novel polypeptides possessing part or all of the primary structural conformation and one or more of the biological properties of a mammalian (e.g., human) pluripotent granulocyte colony-stimulating factor ("hpG-CSF") which are characterized in preferred forms by being the product of procaryotic or eucaryotic host expression of an exogenous DNA sequence. Sequences coding for part or all of the sequence of amino acid residues of hpG-CSF or for analogs thereof may be incorporated into autonomously replicating plasmid or viral vectors employed to transform or transfect suitable procaryotic or eucaryotic host cells such as bacteria, yeast or vertebrate cells in culture. Products of expression of the DNA sequences display, e.g., the physical and immunological properties and in vitro biological activities of isolates of hpG-CSF derived from natural sources. Disclosed also are chemically synthesized polypeptides sharing the biochemical and immunological properties of hpG-CSF.

Abstract: A polymer lactide is prepared by the polymerization of meso-3,6-dimethyl-1,4-dioxane-2,5-dione or mesodilactide and, if desired, other monomers. The mesolactide monomer has preferably a free acid content of less than 1 meq/kg dilactide and is then polymerized in a manner known per se. The compositions containing polymesolactide obtained according to this process do not posses the typical characteristics of poly-DL-lactide, poly-D-lactide or poly-L-lactide. A shorter degradation time of a substrate based on the present polymer is unofficial for several purposes. The present polymers have a good biocompatibility and are thus suited for bone plates, clamps and sutures and controlled release of biologically active compounds. The present polylactides and/or copolymers thereof have the benefit of a good biodegradability, biocompatibility, non-toxicity and non-mutagenicity.

Abstract: A method is disclosed for using quasielastic light scattering to determine the degree of cataractogenesis of a lens in vivo. By collecting and analyzing light (18) scattered from the lens, it is possible, using the autocorrelation function or the power spectrum (160), to separate the fluctuations into two components: one caused by fast diffusing proteins and one caused by slow diffusing protein aggregates. This data may be applied to an experimentally determined and theoretically deduced universal curve in order to determine quantitatively (170) the degree of cataractogenesis at that particular location in the lens.

Abstract: The invention relates to a method and device for changing troughs of dumpers with interchangeable troughs. In underground mining it is problematical to carry out a trough change because of the laterally restricted conditions since the troughs cannot be put down next to each other. According to the invention, the empty trough (2) is therefore initially raised from the transport vehicle (1) to such an extent that a full trough (3) can be pulled onto the transport vehicle in place of the empty trough. Subsequently, the empty trough is let down and put in place of the full trough. While the full trough is transported away, the empty trough left at the site can be loaded so that a quasi-continuous transport is obtained. <IMAGE>
