Preferably the coating for the adhesive substance contains one or more film-forming substances selected from the group consisting of ethyl cellulose, saccharose monostearate, gum arabic, cellulose acetate phthalate, acrylate polymers, methacrylate polymers, shellac or other film providing substances.

Abstract: A method for preparing a substrate capable of undergoing catalytic-induced hydrolysis of the phosphate ester at the 3' position, to yield a species capable of being monitored spectrophotometrically or fluorometrically, comprises(a) forming a mononucleotide 20', 3' cyclic phosphate of the formula: ##STR1## wherein B is a nucleotide base, and wherein the CH.sub.

Abstract: p-Nitrophenylester of succinoylaminopropyl silica gel is useful as an affinity matrix for reacting with ligand for use in affinity chromatography. The affinity matrix, upon reaction with a ligand, releases one molecule of p-nitrophenolate ion for every molecule of ligand that reacts and the solution turns yellow as the reaction occurs.

Abstract: Improved diazonium affinity matrixes are provided which are storable stable and may be stored for extended periods for future use. The improved affinity matrixes are diazonium silica gel affinity matrixes containing an amine linkage and especially the fluoborate salts thereof.

Abstract: Monohydroxy-benzoyl peroxide of the formula ##STR1## possesses both antibacterial and comedolytic activity and is useful in compositions for the treatment of acne.

Abstract: A pharmaceutical preparation for the topical treatment of acne is disclosed comprising a combination of Imazilil and Hexamidine as essential active substances. This combination shows antimicrobial activity higher than that of the individual substances.

Abstract: A pellicle for use in projection printing comprises a pellicle in which the transparent film is formed from a polyvinyl butyral resin or from a casting composition which is a mixture of a polyvinyl butyral resin and a dispersion of colloidal silica and a silicone resin which is a lower aliphatic alcohol-water solution of the partial condensate of a silanol. A pellicle employing such films are useful in the near, mid and deep UV regions.

Abstract: A liquid dispenser for attachment to or forming part of a liquid container including a bore and a plug portion of substantially the same cross-section as the bore mounted in and across the bore so that the outer surface of the plug and the inner surface of the bore are in sealing contact, the outer surface of the plug portion or the inner surface of said bore including a protrusion whereby the plug or brush holder are distorted to provide a liquid channel for control of the flow of the liquid between the outer surface of the plug and the inner surface of the bore.

Abstract: A pellicle for use in projection printing comprises a pellicle in which the transparent film is formed from the novel film forming reaction product of a polyvinyl butyral resin with a silane. Pellicles employing such films are useful in the near, mid and deep UV regions.

Abstract: The present invention provides method and apparatus for forming a collapsible trap for trapping flying insects, particularly Gypsy moths. The trap includes a housing or enclosure with at least one entrance port into said housing for enabling insects to enter, and an overhead shade above this port to guide the insect into the port and to block from the port sunlight, which might otherwise attract the insect away from the trap. A sex lure and a volatile insecticide are provided within the housing to attract insects inside and then to exterminate them. The housing is formed from a single integral sheet of stiffly flexible material, such as water-resistant coated cardboard or plastic, having multiple panels joined together along crease lines acting as hinges. The trap can be folded along two of its crease lines into a flat configuration for advantageously facilitating transport, handling, and storage of the trap in its collapsed state.

Abstract: Stripping compositions for removing resist materials from substrates comprise compositions of a 2-pyrrolidinone compound and a diethylene glycol monoalkyl ether compound. Polyethylene glycol may be added to provide even more effective stripping compositions.

Abstract: Compositions employing titanium dioxide as an opacifying agent and which are thixotropic gels easily convertible to pourable liquids with moderate shaking are provided by employing Avicel.RTM. RC-591 as the suspending agent for the composition.

Abstract: Filling with water-containing raw materials for nutrient bars with covering sheets made of waffles or the like with vegetable fibrous material especially wheat bran added to the water-containing raw materials and the moisture content of the filling amounts to 5 to 20 percent by weight. The addition of non-water-containing raw materials like oil seed products, such as hazel nut marrow, is possible.

Abstract: An improved sanitizing formulation contains a peroxy hydrate compound, a non-phosphate water softener, a source of magnesium ion as a partial hydrogen peroxide stabilizer, a chelating agent for transition metals and a nonionic surfactant.

Abstract: Stripping compositions for removing resist materials from substrates comprise compositions of dimethylacetamide or dimethylformamide or a mixture thereof and a tetrahydrothiophene 1,1-dioxide compound.

Abstract: The present invention provides a trapping method and trap apparatus for flying insects exhibiting phototropic behavior, particularly gypsy moths. The trap is designed to utilize the insect's phototropic reaction both (a) to aid in inducing it to enter into an enclosure or trap and (b) to keep it inside away from the opening or openings for a sufficient time for a volatile insecticide within the trap to kill the insect. The trap includes a housing formed, in an upper part, from light-transmissive material with at least one opening defined in the housing below its light-transmissive portion. An insect is lured into the housing through the opening primarily by a female sex attractant, and also is lured by the illumination entering through the light-transmissive top, and once inside, is attracted upwardly towards the top of the housing and away from the opening by light entering through the light-transmissive top of the housing.

Abstract: Stripping compositions for removing resist materials from substrates comprise compositions of a 2-pyrrolidinone compound and tetrahydrofuran compound. Either or both of polyethylene glycol and a diethylene glycol monoalkyl ether may be added to provide even more effective stripping compositions.
