Abstract: A visually verifiable and machine-readable security thread having at least two security detection means located thereon, where a first security detection means comprises a machine-readable repeating pattern and where a second security detection means comprises visually verifiable metal-formed indicia. Such security threads are suitable for use with security documents, such as banknotes and the like, labels and any other documents or means of identification used for purposes which make the verification of the authenticity of each specimen desirable at least once in its lifetime.

Abstract: A method of producing an externally non-conductive hose assembly is provided which is made up of a hollow cylindrical member novelly connected to coupling means, where the connection prevents the dissipation of electrical charges therethrough and has sufficient strength to withstand severe torsional stresses and provides a seal to substantially preclude the undesired and gradual escape of fluids over the lifetime of the assembly.

Abstract: The production of high purity oxygen and hydrogen gases can be accomplished utilizing an electrolysis assembly comprising an anode, a cathode, an ion exchange membrane disposed therebetween, an anode chamber, and a cathode chamber. This ion exchange membrane has been multiply impregnated with catalyst and therefore contains internal catalyst sites where hydrogen gas, which diffuses through the ion exchange membrane from the cathode chamber, and oxygen gas, which diffuses through the ion exchange membrane from the anode chamber, react to form water. Reacting the hydrogen and oxygen gases within the ion exchange membrane prevents these gases from contaminating the oxygen stream in the anode chamber and the hydrogen stream in the cathode chamber, respectively.

Abstract: Water based silicone coating compositions are provided offer superior coating properties, durability and resistance to high temperatures and to the effects of corrosive environments. These coating compositions are especially useful for coating the external and intricate internal surfaces of high temperature aluminum heat exchangers.

Abstract: A high performance ionomer assisted electrolytic cell electrode structure is provided. Such structures operate effectively at catalyst loadings as low as 0.10 mg/cm.sup.2 and demonstrate increased structural integrity without ionomer degradation. The inventive structure comprises a hydrated ion exchange membrane having a first surface and a second surface and at least one catalyst ionomer layer bonded to the first and/or second surface of the membrane that comprises hydrated and swollen ionomer solids bonded to discrete catalyst particles.

Abstract: A sensor head (1) is described, which has a spacer (5b) between a carrier element (2) and the spring arm (7), which, perhaps carries a sensor tip (9) at the free end; the spacer defines the distance d between the spring arm (7) and the carrier element (2). In a preferred embodiment, the spacer (5b) comprises a sacrificial layer (5a), which is etched out, except for the spacer (5b), after the formation of a corresponding layer system between the spring arm (7) and the carrier element (2). The carrier element (2) and the spring arm (7) are each provided with a reflecting layer (4 and 6). In accordance with another specific embodiment, plasmonactive layers can also be provided.

Abstract: A catalyst for oxidizing aqueous organic contaminants includes about 5 wt % to about 20 wt % noble metal crystallites selected from the group consisting of platinum, palladium, ruthenium, iridium, and combinations thereof deposited on a high surface area catalyst support. The crystallites are about 100 .ANG. or smaller. A system for catalytically oxidizing aqueous organic contaminants has a catalyst bed containing such a catalyst, means for heating a reactor feed stream to a desired reaction temperature, means oxygenating the feed stream, and a phase separator for separating gaseous reaction products from a reactor effluent stream.
