Abstract: Liquid fuels such as a diesel engine fuel mixture or a light heating oil have as a main component, a fossil diesel engine fuel and/or a biodiesel and/or a vegetable oil and additives. The object is to provide an alternative mixture component for diesel engine fuels or light heating oil which is suitable not only for fossil diesel engine fuels but also biodiesel or vegetable oil, which may be produced inexpensively and which meets the requirements as a pure bio propellant. It is proposed that diesel engine fuel mixture or light heating oil contains, as a mixture component, diethyl oxalate. The heating oil can be made of a mixture which originates from the refining of crude oil and is admixed with up to 25% by volume diethyl oxalate. In addition, for the heating oil, use can be made of a mixture which consists of vegetable oils and up to 50% by volume diethyl oxalate.

Abstract: A method of preparing hot tea for immediate use uses green or black tea leaves or mixtures of the leaves and untreated water that originates from the local supply network as the brewing water. The novel method aims to prevent clouding and the formation of a skin after the brewing process with little effort, cost-effectively and without influencing the flavor or hygienic properties of the tea. Prior to or during the heating of the brewing water, or during the brewing process, potassium-, sodium- or ammonium citrate are added individually or as a mixture, to produce a pH value of between 5 and 7 in a purely aqueous solution. As a result of the addition, the brewed tea is translucent and devoid of the usual clouding and formation of a shimmering skin on the surface.

Abstract: The invention relates to a fast-acting composition for preparing cold and hot drinks from drinking water, in particular coffee or tea. Starting from the disadvantages of the known prior art, it is an object of the invention to provide a fast-acting composition for preparing cold and hot drinks from drinking water which is simple to handle, has a uniformly constant action, excludes the risk of microbe formation and, after a relatively short treatment time of the drinking water, leads to a noticeable improvement in taste of the drink. For this, as a solution a composition is proposed which consists of cellulose fibers which are modified by chemical reaction with formation of phosphate ester groups and have an ion-exchange capacity of at least 50 mg of copper/g of dried fiber, this composition being contacted by immersion with the drinking water or brewing water at least briefly, for a period of a plurality of minutes.

Abstract: The invention relates to a method of joining two bevelled rod ends composed of plastics material reinforced with long fibres, using a shrinkable tube.

Abstract: A mixture comprising 1. from 70 to 99% by weight of a predominantly aromatic polycarbonate; and 2. from 30 to 1% by weight of a polyolefin graft polymer of (a) 70 to 95% by weight of a graft base consisting of a homopolymer of aliphatic and/or aromatic monoolefins or of a copolymer of these olefins, and up to 50% by weight of other monoolefinically unsaturated, radially polymerizable compounds and/or up to 5% by weight of diolefins, and (b) 5 to 30% by weight of at least one graft-polymerizable vinyl compound, the olefin graft polymers having been obtained by contacting a melt of the graft base (a) with oxygen or an oxygen-containing gas for at most 10 min. with intensive mixing under a pressure of from 1 to 150 bars and at a temperature of from 80.degree. C. to 300.degree. C., adding the vinyl compounds (b) to be grafted on immediately afterwards with intensive mixing in the absence of oxygen or oxygen-containing gas and removing the residual monomers after the graft polymerization reaction.

Abstract: Polymer blends consisting of from 60-99 % by weight of polyamide and of from 1-40 % by weight of a graft product of polyethylene or copolymers of ethylene with grafted units of (meth)acrylic acid and/or (meth)acrylic acid derivatives and/or maleic acid which graft products have been prepared by a special grafting process.

Abstract: High impact resistant polymer blends comprising 70-99% by weight of a polyamide and 1-30% by weight of a polyethylene having been oxidized by a special process.

Abstract: The toughness of thermoplastic polyesters can essentially be improved by addition of a new type of graft polymers which contain one grafting site for about 400 to 2000 carbon atoms, the average molecular weight M.sub.w of the graft branches being from 2000 to 40,000.

Abstract: Molding compositions comprising a "terminally unsaturated"polyurethane, a copolymerizable vinyl or vinylidene compound and a rubbery-elastic polymer having a glass transition temperature of between -90.degree. and +10.degree. C. can be used for the preparation of molded articles having a considerably increased impact strength and a good heat distortion temperature, strength and rigidity.

Abstract: A continuous process for the production of graft polymers of oxidizable polymers as backbone and radically polymerizable monomers for forming the side chains, characterized in that an intensively stirred melt of the backbone polymer is brought into contact for at most 10 minutes with oxygen or oxygen-containing gases under a pressure of from 1 to 150 bars and at a temperature of from 100.degree. to 300.degree. C., immediately after which one or more radically polymerizable monomers is/are added with intensive stirring in the absence of oxygen and oxygen-containing gas, and after their polymerization the graft polymer formed is isolated.
