摘要:
The invention relates to an electric heating device for heating fluids, comprising at least one heating rod, which has at least one heating element, a housing, which encloses the heating rod and has an inlet opening and an outlet opening, wherein the inlet opening and the outlet opening are interconnected by a winding flow channel. According to the invention, the flow channel forms a helix that has a longitudinal axis, wherein the heating rod is disposed next to the longitudinal axis of the helix and extends through a helically winding wall of the flow channel at a plurality of points.
摘要:
The invention relates to aqueous dispersions of alkaline earth metal soaps and/or alkaline earth metal resin soaps for deinking printed wastepaper in which the dispersions containA. alkaline earth metal salts of C.sub.6-22 carboxylic acids and/or resinic acids andB. C.sub.6.22 oxoalcohols alkoxylated with 2 to less than 6 mol C.sub.2-4 alkylene oxides and alkali metal and/or alkaline earth metal alumimo silicates corresponding to general formula I 0.7-1.5 cat.sub.2/n O.Al.sub.2 O.sub.3.0.8-6 SiO.sub.2in which cat represents alkali metal and/or alkaline earth metal cations and n is the valency of the alkali metal and/or alkaline earth metal cations.
摘要:
A water insoluble lipophilic emulsifier having a hydrophile-lipophile balance (HLB) of 3.5 to 7, added to an aqueous dispersion containing a polymer comprising acrylic acid, methacrylic acid, their alkyl esters, and/or their alkylaminoalkyl esters, acts as a lubricant and parting agent when the resulting mixture is used for coating pharmaceutical dosage forms and prevents the pharmaceutical dosage forms being coated from sticking to one another and to the walls of the coating apparatus used.
摘要:
A conversion product of polysuccinimide useful as coating material for medicinal preparations and foodstuffs having the structure: ##STR1## wherein A is hydrogen or a straight or branched alkyl or alkylene group of 1 to 8 carbon atoms, optionally substituted by cycloaliphatic or aromatic groups, wherein the cyclic substituent can also contain heteroatoms, or by R--O--, ##STR2## or R.sub.3 R.sub.4 N groups, wherein R, R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are hydrogen or branched alkyl or cycloalkyl groups each of which may contain oxygen and nitrogen atoms in the chain or in the ring of 1 to 10 carbon atoms;B is hydrogen or straight or branched chain alkyl or alkenyl, and is the same or different from A;D is hydrogen, NH.sub.4, ##STR3## wherein A and B have the aforementioned meanings, or an alkali metal ion; anda is 0.2 to 1 and b is 0.8 to 0.
摘要:
Process for deinking printed waste paper by treatment of the paper pulp in a pulper at alkaline pH values using alkali silicate, oxidative bleaches, higher fatty and/or resinic acids and dispersants and separation of the detached printing ink particles from the fiber suspension by flotation, the fatty and/or resinic acids being used in the form of their alkaline earth metal salts in fine distribution together with dispersants in an oil-in-water dispersion which is liquid at normal temperature.
摘要:
Aqueous dispersions of a water-swellable but water-insoluble polymer formed between a quaternary ammonium monomer and a nonionic monomer; methods for making such dispersions by dispersing said copolymers, in the form of a powder, in water; methods for coating pharmaceutical cores, powders, or granules with such dispersions; and coated pharmaceutical products made by such methods.
摘要:
Roof cladding which may be used in different ways as a building element to allow heat exchange with the environment. Each element has hollow chambers and is extrudable in a plurality of layers with a transparent upper layer (1). The hollow ends of the elements are connected in two collection channel systems (15,17) which may be operated in series or parallel according to the desired operating mode.
摘要:
A dermal therapeutic system which exhibits a prolonged release of a drug comprising at least one pharmaceutical agent combined with poly(meth)acrylates in the form of at least one layer of the therapeutic system, the poly(meth)acrylates being a mixture, which is produced from a melt, comprising (1) at least one (meth)acrylic polymer containing functional groups and (2) at least one (meth)acrylic polymer which regulates the flow behavior of the poly(meth)acrylate mixture and which contains no functional groups or only insignificant amounts of functional groups.
摘要:
Thermoplastic materials which comprise a copolymer of (A) 16 to 40 wt % of acrylic and/or methacrylic acid; (B) 30 to 80 wt % of methyl acrylate; and (C) 0 to 40 wt % of another alkyl ester of acrylic and/or methacrylic acid and perhaps conventional auxiliaries for drug coatings are suitable for the production of drug coatings which are soluble in intestinal juices, such as tablet coatings, dies, films, capsules, or multipart dosage units.
