Abstract: The invention relates to laminated parts comprising outer layers and polyurethane sandwich materials, and to a method of producing these laminated parts and to their use in the automotive industry.

Abstract: Activators with reduced volatility that are liquid at room temperature are obtained as the reaction product of (A) a secondary amine or primary alcohol having at least one tertiary amine group, (B) a polyisocyanate of the diphenylmethane series having a functionality of from 2.5 to 4.0 and an OH-functional reactive component capable of addition to isocyanate. These activators are useful for the production of polyurethane foams having improved emission behavior.

Abstract: The present invention relates to polyol dispersions with long-term stability, to cellular polyurethane moldings produced therewith, to processes for their preparation and to their use.

Abstract: The present invention is directed to cellular amine-crosslinked polyurethane elastomers, a process for preparing these elastomers and to the production of various parts of shoes and soles of shoes from these elastomers.

Abstract: Multi-ply laminated materials based on wood veneer are produced by pressing veneer woods glued with a specified binder which enhances the cold bond strength of the laminate.

Abstract: Polyurethane elastomers are produced by reacting a polyether and/or polyester polyol having a starter functionality of at least 2 with an NCO-terminated prepolymer produced with a polyether and/or polyester polyol having a starter functionality of at least 4. These polyurethane elastomers exhibit improved processing characteristics combined with a high heat distortion temperature.

Abstract: A drive system has a load, a driven surface which is spaced from the load, and a mechanical connection which connects the driven surface with the load and is operative for oscillating the driven surface and the load relative to one another, so that the mechanical connection displaces the driven surface with respect to the load with a force selected such that the driven surface obtains a velocity which is at least equal to a local sonic velocity and therefore a sonic shock is created and opposes the displacement of the driven surface away from the load, and thereafter the mechanical connection displaces the load away from its initial location.

Abstract: Composite materials are made by press molding a lignocellulose-containing materials glued with a specified type of binder in which the cold bonding strength of the molded lignocellulose-containing material is increased.

Abstract: The present invention relates to improved internal mould release agents based on particular ammonium or metal salts of phosphoric acid esters, ammonium salts of carboxylic acids and/or ammonium or metal salts of sulfonic acids for producing cellular or compact, optionally glass fiber- and/or natural fiber-reinforced polyurethane mouldings. The polyurethane mouldings produced according to the invention may be laminated or coated with other materials.

Abstract: A seat belt buckle having a release button for a latch slidably mounted on a frame, an ejector for an insert tongue and at least one connecting element. The connecting element is shiftable between a working position, in which it makes a connection between the ejector and the release button, and a resting position in which it breaks the connection between the ejector and release button. A dislocator is provided on the frame, which dislocates the connecting element from the resting position into the working position when the ejector is shifted out of place.

Abstract: The invention provides a process for preparing flexible to semi-rigid polyurethane moulded items with compacted edge zones with given hardness and a much more flexible cellular core, so-called integral foams, in which physical blowing agents from the set comprising C6 hydrocarbons are used.

Abstract: A problem in pulse oximetry is discriminating between arterial and non-arterial oxygen. Non-arterial oxygen can become detectable by an oximeter when a patient moves, obscuring the oximeter's measurement of arterial oxygen at critical times. Recent advances in pulse oximetry have made it possible to make the discrimination between arterial and non-arterial blood oxygen values. To allow manufacturers, hospitals, and medical researchers to evaluate the new oximetry technology, and evaluate oximeters which use it, new simulation technology is presented which can simulate simultaneous arterial and non-arterial blood oxygen on demand, with precision as to oxygen value, waveform amplitude, and waveform frequency. This invention provides the required simulation by double amplitude modulating the red and infra-red oximeter pulses.
