摘要： A process for producing polyurethane foam articles is described, in which the article is produced in the conventional manner by foaming in a mould and a release agent is applied to the mould surface prior to filling with the foam-producing components. According to the invention, a solvent-free, aqueous release agent is used in combination with one or more alkali metal and/or ammonium salts of higher fatty acids and one or more higher alcohols and the combination is applied in the hot state, preferably at a temperature of at least 75.degree. C. to the mould surface. In addition, an additive is described, which is suitable for performing the process according to the invention and contains one or more alkali metal and/or ammonium salts of higher fatty acids, one or more higher alcohols and otherwise water. The process according to the invention has the advantage that it not only avoids the use of environmentally prejudicial organic solvents, but also leads to excellent release agent films, from which the water is very largely evaporated within a very short time and namely within the very short cycle times of modern foam plants.

摘要： A novel aqueous release agent is described, which contains as release-active subtances oil and/or wax emulsified in water as the carrier and which also contains as a further release-active substance one or more aliphatic primary, secondary and/or tertiary amines with at least one C.sub.12 -C.sub.24 alkyl radical and one or more ammonium salts as the emulsifier for the amine or amines. The invention is based on the surprising finding that hydrophobic amines (so-called fatty amines) are release-active substances. It has also surprisingly been found according to the invention that when using ammonium salts as the emulsifier, mould removal characteristics are not only impaired, but often even improved, which is not the case with conventional emulsifiers. The release agent according to the invention is particularly suitable in processes for producing polyurethane foam articles.

摘要： A water- and solvent-free release agent for use in the production of articles of polyurethane foam contains one or more polyenes as the main constituent and also in addition if required a consistency adjuster, an antioxidant, accelerators and/or stabilizers. To apply water- and solvent-free release agents to the surfaces of polyurethane-foam moulding dies the misting or atomization of the release agent is effected with a device with an electrostatic charge, by which the release agent particles are given an electrostatic charge when passing through the exit nozzle.

摘要： A release agent is described, which is suitable for the production of polyurethane foam articles in molds. It is an aqueous emulsion or dispersion of per se known release-effective substances as well as optionally conventional additives, having a water content of at least 60% by weight and preferably 85 to 96% by weight, the water being masked through the effect of lyotropic mesomorphism. Masking and immobilizing the water molecules avoids that the water molecules have a prejudicial effect of the polyol/isocyanate reaction, and is preferably achieved by the combined use of release-effective substances and suitable masking aids. As suitable masking aids especially fatty alcohol polyglycol ethers and ethoxylated fatty alcohols are proposed. The polyurethane articles obtained while using the above described release agent fulfil the standard quality requirements without any of the disadvantageous effects on the environment such as occur with conventional release agents.

摘要： The present invention relates to novel polymer compositions and the novel method of their synthesis. The novel polymer compositions are synthesized by forming a tetrahydrofuran solution of a polymer selected from the group consisting of polyvinylchloride, polystyrene, and silicone; adding an anhydrous manganese salt of the formula:MnX.sub.2wherein X is a species capable of forming an anion, preferably a halogen or a thiocyanate, then adding to the solution of polymer and manganese salt, a phosphine of the formula:PR.sup.1 R.sup.2 R.sup.3wherein R.sup.1, R.sup.2, and R.sup.3 may be the same or different, and each is selected from the group consisting of substituted or unsubstituted alkyl, cycloalkyl or aryl groups or hydrogen, provided that no more than two of the groups R.sup.1, R.sup.2, and R.sup.3 are substituted or unsubstituted aryl groups and that at least one of the groups R.sup.1, R.sup.2, and R.sup.3 is a substituted or unsubstituted alkyl, cycloalkyl or aryl group. Films formed from the novel polymer composition have particular utility in reversibly complexing with gases such as oxygen, hydrogen, sulfur dioxide, alkenes, carbon monoxide and the like.

摘要： A nuclear radiation detection system for remote monitoring of movement of nuclear material over a road or highway. Nuclear fiber sensors, which may be several meters long, are covertly positioned in at least two monitoring points, such as buried shallowly under the roadway or hung from a tunnel wall, along the path which a nuclear source may be clandestinely moved. These fiber sensors are individually connected, by an epoxy glue, to individual transmitting optical fibers. Movement of a nuclear radiation source in close proximity to the fiber sensors at the two or more monitoring points produces an optical signal which exceeds a preestablished threshold. These optical signals travel through the transmitting optical fibers, which may be about 1 kilometers long, to a electronic system comprised of a microprocessor controlled signal detecting, signal processing and even data storage means. The optical fibers and electronic system are also selectively hidden from view for security reasons. Any movement of a nuclear source is detected by strength and duration radiation signal data which is stored in the microprocessor memory. This data may be removed from the processor and read out by a data key means.

摘要： The present invention relates to a novel method and apparatus which can provide continuous monitoring of the oxygen content of a gas over an indefinite period of time and at a minimal cost.In the novel apparatus of the present invention, a light source and a light sensitive detector are disposed within the atmosphere to be measured, and a polymeric film formed from a manganese tertiary phosphine polymer complex is deposited between the light source and the detector. As oxygen pressure increases or decreases a change in color intensity of the film takes place which controls passage of light from the light source to the detector. The detector in turn is suitably connected to an audio and/or visual warning device and/or a recorder which will provide the desired form of warning.

摘要： Method and apparatus which can provide continuous monitoring of the partial pressure of one or more gases in an atmosphere or feed stream, over an indefinite period of time and at a minimal cost. The method and apparatus of the present invention operates by monitoring the change in frequency of a piezoelectric element which has been coated with a film formed from manganese tertiary phosphine polymer complex. As the polymer absorbs or releases gas the frequency of the piezoelectric device will be altered.
