Abstract: Provided herein are lignocellulosic composite articles and methods for forming the same. In an aspect, the lignocellulosic composite articles comprise a plurality of lignocellulosic pieces derived from wood; together with an adhesive system disposed on the plurality of lignocellulosic pieces for bonding the plurality of lignocellulosic pieces. In an aspect, the adhesive system comprises a binder component comprising diphenylmethane diisocyanates (MDIs) and/or polymeric diphenylmethane diisocyanates (pMDIs), and a catalyst component comprising imidazole in a water solution.

Abstract: A lignocellulosic composite article includes a plurality of lignocellulosic pieces and an adhesive system disposed on the plurality of lignocellulosic pieces for bonding the plurality of lignocellulosic pieces. The adhesive system comprises a binder component and an additive component. The binder component comprises a diphenylmethane diisocyanate (MDI), a polymeric diphenylmethane diisocyanate (pMDI), and combinations thereof. The additive component comprises an amine compound and water. The amine compound can be imidazole. The additive component is useful for reducing the amount of press time required during manufacture of the composite article.

Abstract: The present invention relates to an optically transparent glass foam or glass-ceramic foam as well as to a method for the production of an optically transparent glass foam or glass-ceramic foam. A method is described for the production of optically transparent foams, wherein the following steps are conducted: a) Mixing of pre-ceramic Si polymer, glass powder and glass converter; b) Heating of the mixture to a temperature below the decomposition temperature of the pre-ceramic Si polymer with the formation of a foam; c) Heating the obtained foam to a temperature above the decomposition temperature of the pre-ceramic Si polymer; d) Heating the obtained product to a temperature between 700° C. and 1400° C. with the formation of glass; and e) Cooling the thus-obtained product to ambient temperature.

Abstract: Methods for crosslinking polysiloxane compounds, crosslinked polysiloxane compounds, methods for making ceramic products from the crosslinked polysiloxane compounds, and ceramic products made from the crosslinked polysiloxane compounds.

Abstract: An electromagnetic relay especially such a relay with a spring jack, that serves for holding the magnet coil and the contact spring jump. In the simplest form of the relay, it includes the feature that the individual contact springs of the contact spring jump are provided with one piece fitted flat plugs, which are positioned in grooves in the ground wall of the spring jack, and in such position are securely fixed from the standpoint of strength and form.
