Abstract: The invention relates to the monitoring of products by means of active radio tags. According to the invention, packagings of products are provided with an active radio tag that detects at least one environmental condition and/or at least one packaging state, and which emits a signal at time intervals, which provides information about a unique identifier and at least one state in which the respective product is found. The signal is picked up by a receiver that extracts the unique identifier and the state information and transmits same together with location information to an external server.

Abstract: The present invention pertains to an adjustable canister purge valve (9) and method having a first connection (10) for an intake pipe (11) of an engine and a second connection (14) for an activated carbon filter (5). The first (10) and second connection (14) are interconnected by means of a first adjustable valve (16) enabling the flow of a regenerating mixture (8) of air and fuel-vapor. A second valve having a larger flow cross-section (22) is connected in parallel with the first valve (16) and allows a large regeneration air flow, even with a low suction vacuum, and thus improved purge.

Abstract: In the method, following an operating point determination of the quartz resonator circuit, a substitution of the equivalent circuit diagram of the quartz resonator by an independent current source is implemented with the initial, previously determined amplitude of the current of the dynamic arm of the quartz resonator. The dynamic equilibrium state is determined for this circuit arrangement with firing methods or methods of harmonic balance. After a resubstitution of the current source by the equivalent circuit diagram of the quartz resonator, a transient analysis is implemented for the dynamic equilibrium state. This method is iteratively implemented as long as the identified growth rate lies above a prescribable barrier.

Abstract: Aqueous aminoresin solutions for low-formaldehyde surface bonding, based on condensates of melamine, urea, phenol and formaldehyde having a molar ratio of from 1.4 to 1.8 moles of formaldehyde, from 0.04 mole to 0.1 mole of melamine and from 0.015 to 0.04 mole of phenol per mole of urea, relative to the total amount of the aminoresin, are obtainable by mixing(A) from 20 to 40% by weight of melamine/urea/phenol/formaldehyde consensate with(B) from 60 to 80% by weight of a urea/formaldehyde condensate.

Abstract: Woodworking materials having a lower subsequent formaldehyde emission can be prepared in an advantageous manner and with good resin reactivity and good strengths and swelling properties by mixing lignocellulose-containing particles, for example wood particles, with a curable binder based on curable aminoplast condensates and then pressing the mixture under the action of heat, a mixture A containing a water-compatible agent for binding formaldehyde being applied to or mixed with the particles before the latter are mixed with the curable binder, if the mixture A is an aqueous solution which has a pH of from 3.0 to 6.5 and contains(a) organic acids which attack wood only insignificantly, if at all, in an amount of more than 15% by weight, based on the solids content of the solution, preferably a mixture of aliphatic carboxylic acids of 4 to 10 carbon atoms, and(b) a formaldehyde-binding, nitrogen-containing compound, in particular urea.

Abstract: A regular thread spool has at least one of its end flange disks provided with a sectionalized groove, the sections being axially offset to provide thread retention baffles.

Abstract: Improvement of the cold adhesion of glue resins, particularly phenoplast and aminoplast wood glues, by the addition of small amounts of a ligninsulfonate.
