Abstract: Copper powder has a coating made of copper phosphate at the outer surface thereof. The coating is formed by chemically reacting the outer surface of the copper powder and covers the entire surface of the copper powder uniformly, thereby obtaining excellent anti-oxidizing properties. It is preferable to set the copper phosphate ratio in term of phosphorus with respect to the total weight of the copper powder within the range of about 0.05 to 0.5 wt %.

Abstract: Flexible graphite sheet is made by compressing a mixture of fine particle of intercalated, exfoliated, expanded natural graphite with fine particles of intercalated, unexpanded, expandable particles of natural graphite admixed with small amounts of a phosphorous bearing compound, the unexpanded particles being more finely sized than the expanded particles. The resulting sheet of flexible graphite exhibits improved fire retardant and sealability properties and additionally resistance to oxidation and corrosion.

Abstract: The invention relates to a process for manufacturing an article of a high-density carbon. To produce an un-fired compact, binderless, self-sintering, fine-grained carbon powder, particularly carbon mesophases, with a powder density of more than 1 g/cm.sup.3, particularly more than 1.4 m/cm.sup.3, and an average grain size of between 5 and 20 .mu.m, is precompacted at a low pressure and is pressed in a mold to at a pressure of between 50 and 150 MPa, particularly at approximately 100 MPa. After pressing, the contact pressure is slowly lowered. Then, the un-fired compact is carbonized in a temperature gradient of maximally 20 K/min. The temperature is held constant at a holding temperature of between 500 and 700.degree. C. for a defined holding time and is subsequently raised to a maximal temperature of between 800 and 1,200.degree. C., particularly approximately 1,000.degree. C. Finally, the carbonized compact is graphitized at an end temperature of between 2,500-3,000.degree. C.

Abstract: The invention provides molded, extruded or formed phosphorescent plastic articles having laser marked indicia and methods for preparing the articles. The indicia may be seen as a contrast against a phosphorescent background or, alternatively, the indicia may themselves be phosphorescent. An article of the invention has a composition comprising about 50% to about 99% by weight of a thermoplastic or thermosetting resin, about 1% to about 50% by weight of a phosphorescent phosphor pigment and about 0.001% to about 1% by weight of a laser energy absorbing additive. Resin compositions which themselves are laser energy absorbing do not require the additive; however, the addition of small quantities of the laser energy additive enhances the quality and contrast of the laser mark.

Abstract: The invention relates to a coating comprising a photochromic material, its production and its use. The photochromic material of the coating has an optically reversible photochromic effect, wherein the switching threshold is disposed outside of or in the boundary region of the visible range of the spectrum. According to the invention, the photochromic material is coated with an influencing material, so that the switching threshold of the coated photochromic material is shifted towards wavelengths longer than the switching threshold of the uncoated photochromic material.

Abstract: A multilayer material is described, whose overlay exhibits improved hardness and improved wear-resistance. The multilayer material includes an overlay, which contains 8-18.5 wt. % tin and 2-16 wt. % copper, the balance being lead, wherein the tin is present as a finely crystalline deposit completely homogeneously distributed in the lead. A process for producing sliding elements in which the overlay of lead-tin-copper is applied to the prefabricated semi-finished product by electroplating provides that a ternary, fluoroborate-free electroplating bath is used without brighteners and with the addition of fatty acid polyglycol ester and a grain refining agent including a carboxylic acid.

Abstract: A polyurethane elastomer actuator comprising a polyurethane elastomer 1 capable of deforming due to the orientation by an electric field, wherein the shrinkage displacement occurring at the time of the application of an electric field is transformed into other displacement. This polyurethane elastomer actuator does not require electrolyte and high voltage. Since it is not accompanied by chemical reactions and heat generation, its durability hardly deteriorates. This actuator deforms largely during driving.

Abstract: A method of forming a camouflage pattern, a method of manufacturing a camouflage material in accordance with the pattern, and a camouflage material so manufactured. The method is performed by the taking of a series of photographs in a setting in the environment in which the camouflage configuration is intended to be used. One typical environment might include oak, poplar and birch trees. The individual images of the photographs are then entered graphically into a computer. The computer images are then overlain, one upon another, to form a composite print. Using the computer, the colors in the composite print are separated into a plurality of color prints portraying the predominant colors in the composite print. The colors are identified, and a corresponding plurality of layer screens based upon the individual color prints are made. The layer screens are then employed to screen the identified colors onto a sheet of material.

Abstract: Upper and lower shell members of aluminum-plated steel panels have respective flanges overlapping each other and welded to each other by a laser beam, thereby forming a fuel tank. One of the flanges has a stepped region spaced from the other of the flanges, thereby defining a gap between the stepped region and the other flange. The laser beam is applied to the flanges closely to the gap for discharging unwanted components such as aluminum from a welded area of the flanges into the gap. Therefore, the amount of aluminum contained in the welded area is reduced to increase the bonding strength of the welded area.

Abstract: A laminate for forming carton blanks wherein a desired aesthetic holographic appearance is sandwiched between a reversed printed transparent plastic film and a relatively rigid paperboard material. In another embodiment, printed matter and a clear lacquer are imposed on spaced portions of holographic etchings on a transparent film to eliminate the holographic etchings in those areas leaving a remaining portion of the holographic etchings. A metallized substrate covers the printed matter, the clear lacquer and the remaining holographic etchings which can then be laminated to a relatively rigid paperboard.
