Abstract: Provided is an electrode-connector protecting cap for ambulatory physiological signal measurement comprising a hemisphere cap, a wing positioned at a periphery of the hemisphere cap and having a contact surface connected to the electrode-connector; and an opening for a wire to be passed through and formed in the hemisphere cap, and an electrode-connector including the same, whereby a connection between the electrode and the connector can be protected and the noise occurrence can be prevented.

Abstract: Process for recovering caprolactam from a solution comprising caprolactam dissolved in an organic solvent, said process comprising: a) washing the solution with water or an aqueous alkaline solution, resulting in a washed solution comprising caprolactam and organic solvent and in a washing residue, b) evaporating organic solvent from the washed solution, resulting in caprolactam product, c) optionally, hydrogenating the caprolactam product, d) optionally, evaporating water from the caprolactam product, e) distilling the caprolactam product to recover caprolactam and a distillation residue, f) extracting the distillation residue with an organic solvent in the presence of water to obtain (i) an extract comprising caprolactam dissolved in organic solvent and (ii) an aqueous effluent, and g) recycling the extract to step a) or b).

Abstract: The present invention relates to a process for separating from an aqueous mixture one or more organic substances containing at least one positively charged and/or chargeable nitrogenous group by means of extraction via at least one porous membrane, wherein use is made of an extraction agent which contains at least partially relatively long-chain organic compounds and at least one liquid cation exchanger, and of a membrane that is wettable by either the aqueous mixture or by the extraction agent.

Abstract: A deep embossed high pressure decorative laminate having a plurality of integral tiles with various surface textures bordered by deep embossed portions. Each tile of the laminate has a peripheral thickness greater than the thickness of the non-peripheral portions of the tile. Preferably, each tile has a concave profile along its upper surface when viewed in cross section. A method of producing artwork necessary for the deep embossed high pressure decorative laminate of the present invention comprises assembling a first layer of fibrous sheets impregnated with a thermosetting resin, a second layer comprising a plurality of adjacent tiles comprising a plurality of fibrous sheets impregnated with a thermosetting resin, wherein the tiles were previously pressed and heated, and a third layer comprising a plurality of shims.
