Abstract: This invention relates to a jointing compound of an acrylate/acrylonitrile copolymer containing 2 to 8 carbon atoms in the alcohol component as binder and fatty compounds as plasticizer and also fillers and auxiliaries. Epoxystearic acid methyl ester in particular may be used as the fatty compound while a butyl acrylate/acrylonitrile copolymer in particular may be used as the acrylate/acrylonitrile copolymer. The combination of the two substances results in jointing compounds characterized by a dramatic improvement in elasticity (resilience). Accordingly, they are particularly suitable for substrates with different coefficients of thermal expansion.

Abstract: A device for dispensing solid material from a tube having a longitudinally displaceable internal piston moved by an externally operated spindle threading through the piston. At its base the spindle has a narrowed, non-threaded region, such that when the piston is fully withdrawn into the tube, the threads of the spindle and piston slip if the spindle continues to be rotated. To prevent the piston threads from completely disengaging the spindle threads, the spindle's non-threaded region is shorter than the piston's internal threads. In this way, the spindle will not break even if it continues to be rotated after the piston is fully withdrawn into the tube, yet it readily engages the piston threads when turned in the opposite direction to displace the piston towards the dispensing end of the tube. Thus the device as a whole remains reliably usable.

Abstract: An encapsulated active substance for a manual detergent for hard surfaces comprises an essentially anhydrous active substance with at least one surfactant and at least one liquid polymer carrier encapsulated in a water-soluble or water-dispersible capsule, the active substance containing: less than 25 wt. % of carrier; at least one unbranched or branched, acryclic or cyclic, saturated or unsaturated alcohol with 1 to 10 carbon atoms and one or two primary, secondary or tertiary hydroxy groups and a carbon chain optionally having one or more —O— groups; or being free of glycerol. The encapsulated active substance can be used as a manual detergent for hard surfaces.

Abstract: The invention relates to a low-viscosity hotmelt adhesive containing A) at least one hydrocarbon resin solid at 20° C. with a softening temperature of 70 to 140° C., B) at least one oil with an average molecular weight of >500 and preferably C) a styrene block copolymer. The new hotmelt adhesive is distinguished by a melt viscosity of essentially only 500 to 3200 mPas at 150° C. for a softening temperature of 60 to 115° C. It is preferably used in the field of hygiene for bonding films, nonwovens and/or shaped articles of cellulose derivatives, being distinguished by particular resistance to dermatologically compatible coatings.

Abstract: A process for coating laundry detergent or cleaning product tablets that contain builder(s) and also, if desired, further laundry detergent and cleaning product ingredients, by transporting the tablets on a conveyor belt provided with a multiplicity of apertures and forcing coating material through the conveyor belt apertures from below with a force such that the coating material forced over the conveying plane forms a surge through which the tablets are transported.

Abstract: The toothbrush consists of a brush head with bunches of bristles (2, 3, 4) arranged in a longitudinal bristle bed (1) and a handle (6), which is connected to the bristle bed (1) by a connecting part (5). The length of the bunches of bristles (3, 4) varies in the longitudinal direction of the bristle bed (1) in a wave shape. The first bunches of bristles (2) are situated at the two outer sides of the bristle bed (1), have split bristle ends and are of essentially the same length. The second bunches of bristles (3, 4), whose length varies in the longitudinal direction of the bristle bed (1), are situated between the two outer sides of the bristle bed (1). The inventive toothbrush has an improved cleaning action, especially for interdental spaces but also for the gingival line.

Abstract: An aqueous polymer adhesive is provided containing styrene polymers or styrene copolymers with alkyl acrylate acid/or alkyl methacrylates and a thickener system containing an inorganic thickener and an aqueous dispersion of an acrylic acid/acrylamide copolymer which can be partially replaced by a dispersion of a (co)polymer containing acrylate residues, a dispersion of a (co)polymer containing acrylic acid residues and methacrylic acid residues and polyarethanes. The adhesive has a high initial strength and can be in layers up to 30 mm thick.

Abstract: An apparatus and method for the spray drying of solvent-containing compositions. A liquid or paste-form solvent-containing composition is heated to a temperature above the boiling point of the solvent, transported under excess pressure and at a temperature above the boiling point of the solvent to a relaxation space where it is sprayed to evaporate the solvent. The relaxation space is not under excess pressure and is at a temperature that is above the boiling point of the solvent.
