Abstract: An aqueous resin solution S that comprises an alkali or earth alkali, preferably lithium, sulphamate, hydrogen sulphite, or sulphite, at least one aminoplast resin A, and a curing agent C for the latter, wherein the sulphamate, hydrogen sulphite, or sulphite is present in at least one form of admixed to, and cocondensed within, the at least one aminoplast resin, a method of use thereof to reduce the surface resistance of laminates comprising impregnating at least one layer which is laminated to the surface of the board facing the use side of the said laminates, and laminates obtained by this process

Abstract: The invention is based on a circuit arrangement for the detection of a leakage current or defect current, by means of which the power supply of an electronic circuit can be switched off. It is suggested that a track conductor connected with a signal line or an insulation-layer-free conductor connected with a signal line or an insulation-layer-free part of the signal line itself is arranged such that it crosses a potential leakage or defect current connection path of a short circuit between the power supply lines.

Abstract: Aqueous amino resin compositions comprising amino resins A, formaldehyde-binding additives (auxiliaries) B, which may include hydroxyl-containing polyurethanes B13, acrylic resins C, if desired, in the form of aqueous dispersions, and water, and their use as impregnating compositions for paper for the purpose of producing finished foils and edgings.

Abstract: Impregnating and bonding agent for textiles, comprising a mixture of a resorcinol-formaldehyde precondensate A, a rubber latex B and a melamine-formaldehyde resin C, impregnating process and reinforced rubber articles produced using the impregnates.

Abstract: An aqueous amino resin blend comprises aliphatic linear, branched or cyclic amines A containing at least one primary, secondary or tertiary amino group, at least one hydroxyl group and 2 to 20 carbon atoms, and amino resins B, and is used as an impregnating resin in the production of finished foils and edgings.

Abstract: A process for reducing the heat evolution on dynamic stressing of vulcanised rubber products, using for this purpose, in vulcanizable rubber mixtures, mixtures made from non-selfcuring novolaks A and from unetherified or partially etherified triazine resins B, as a combination of reinforcing resin and curing agent.

Abstract: Water-dilutable etherified melamine-formaldehyde resins obtained by reacting melamine, formaldehyde, a compound having anionic groups and an etherification alcohol in a mixing ratio of melamine:formaldehyde:compound having anionic group:etherification alcohol of 1:(1.7 to 7.0):(0.01 to 0.4):(10 to 30) in the reaction mixture, are prepared in a multistage process and are used for preparing impregnates, especially glass fiber fleece and in paper coating.

Abstract: Amino resin mixture for producing foils and edgings with reduced formaldehyde elimination Aqueous amino resin compositions comprising amino resins A, formaldehyde-binding additives (auxiliaries) B, which may include hydroxyl-containing polyurethanes B13, acrylic resins C, if desired, in the form of aqueous dispersions, and water, and their use as impregnating compositions for paper for the purpose of producing finished foils and edgings.

Abstract: A control system for a vehicle, in particular for a truck trailer, has a control device which switches off the control system upon the occurrence of a fault. The control system of the vehicle includes a bistable mechanical display which can be controlled via a coil arrangement into, in each case, one of its stable positions and then displays either a fault condition or no fault condition. Upon switching off the control device because of a fault which has occured, the display is controlled into the “fault” position, and it remains there even without a power supply. Consequently, a faulty system can be detected at any time even without a power supply switched on.

Abstract: The present invention relates to a composite material that contains 5 to 97%-vol aerogel particles and at least one adhesive and that is characterised in that the diameter of the aerogel particles is smaller than 0.5 mm, a process for manufacturing this, and the use thereof.

Abstract: The present invention relates to melamine-formaldehyde resins comprising a guanamine, to processes for their preparation and to their use for the production of melamine resin films and edgings.
