DNA sequences of the EBV genome coding for EBV-related antigens as well as the EBV-related antigens, fusion proteins containing the EBV-related antigens, recombinant DNA molecules containing the DNA sequences, cells containing the recombinant DNA molecules, processes for producing EBV-related antigens, and diagnostic and pharmaceutical compositions are disclosed.

In a tape cassette, a rotary movement of a reel or hub can be visualized in a technical and aesthetic manner by means of a completely or partly transparent cover above and/or below the reel or the hub. Advantageously, the cover contains at least one space and the reel or the hub at least one contrasting pattern, for example with respect to the shape and color of the cover. The pattern/cover combination can be used for all cassettes containing recording media, in which a movement of the recording medium, in particular of a magnetic tape, of a magnetic disk, of a film, of an optical disk, etc., takes place.

Means for visualization of rotary movement in tape cassettes

Magnetic tape cassette

Packaging for data or recording media, for example for magnetic tape cassettes or compact disks, consists of snapped together lower and upper parts and a support frame, in the end areas of which spring elements are formed which press the lower part and upper part apart. The spring elements are formed in the shape of legs at the end of the support frame, which is in the shape of a crosspiece, into which a resilient clasp can be inserted, the end sections of which press on the insides of the lower part and upper part. Tongues formed on the crosspiece and connected with the legs assure the mechanic stability and torsion stiffness of the support frame along with the most economical use of the material and form receptacles for the secure holding and positioning of the recording medium.

A container for a recording medium, such as a magnetic tape cassette, consists of a receptacle, which receives the recording medium in a partially pocket-like manner, and of a cover pivotably connected with it. The faces and side walls of the container are distributed between the receptacle and the cover in such a way that the receptacle constitutes a face of the container as well as at least a portion of the side walls adjoining this face, while the opposite face of the container is formed by the cover, so that a removal opening for the lateral insertion or lateral removal of the recording medium is formed. If the face formed by the cover directly adjoins a portion of the side wall of the container, also formed by the cover, a manipulation surface is created by means of which the container can be opened, similar to a pocket lighter, by a simple movement of the thumb, while the hand of the user firmly grips the receptacle. By means of this a simple, one-handed manipulation for removal is achieved, while the recording medium is prevented from falling out of the container in an uncontrolled manner.

Coating materials containing aliphatic .alpha.-hydroxyketones of the general formula ##STR1## where R and R.sup.1 are each hydrogen or a hydrocarbon radical of 1 to 4 carbon atoms, as antiskimming agents. These .alpha.-hydroxyketones are particularly useful in paints and finishes based on oxidatively drying alkyd resins.

A process for the preparation of copolymer dispersions having a narrow particle size distribution, and exhibiting dilatant flow over a broad range of concentrations, by emulsion copolymerization of from 1 to 10% by weight, based on total monomers, of .alpha.,.beta.-monoolefinically unsaturated monocarboxylic acids and/or dicarboxylic acids with other monoolefinically unsaturated monomers and with from 0 to 5% by weight of polyolefinically unsaturated monomers in the presence of conventional emulsifiers, dispersants and polymerization initiators, and in the presence or absence of regulators, wherein the monomers are copolymerized in aqueous emulsion, with simultaneous agglomeration but only partial fusion of the initially formed polymer particles, at a temperature near the glass transition temperature of the copolymer formed, and thereafter

Preparation of copolymer dispersions having a narrow particle size

Fabrics of which the warp is sized with water-soluble polymers of acrylic acid and/or their alkali metal salts or ammonium salts, are desized by treating the sized fabric with from 30 to 300 percent by weight of water, based on the dry weight of the fabric, and separating the resulting size solution from the fabric. The recovered size solution can be directly re-used for sizing.

Recovery of sizes

Polyester fibers and cellulose fibers, and blends of these fibers, are dyed continuously with disperse dyes, or dispersed dyes, by continuous application of an aqueous dye liquor which contains, as the essential dyeing assistant, a polyoxyalkylated amine, a polyoxyalkylated amine-oxide and/or a quaternized polyoxyalkylated amine which in 1% strength aqueous solution has a cloud point of not less than 18.degree. C and which is derived from amines which contain at least 2 nitrogen atoms and at least one group which can be oxyalkylated, followed by drying and fixing.

Continuous dyeing of polyester fibers and cellulose fibers

A process for dyeing cellulose fibers and mixtures of the same with synthetic fibers in an aqueous liquor by the exhaustion method in the presence of a water-soluble polymer of acrylic acid or an alkali metal salt or ammonium salt thereof, an alkali metal or ammonium salt of a copolymer of maleic acid and styrene, maleic acid and a vinyl ester or maleic acid and a vinyl ether as a dyeing assistant in an amount of from 0.05 to 2% by weight based on the material being dyed. Level dyeings are obtained and mixtures of fibers can be dyed in a single liquor.
