Abstract: A steel cord (10) adapted for the reinforcement of elastomers, comprises individual steel filaments (12, 14). Some of these steel filaments (12) have a difference in torsion saturation level in comparison with other steel filaments (14). All of the individual steel filaments have a predetermined number of residual torsions and are preferably free of residual torsions. Such a steel cord is manufactured by making use of two false twisters.

Abstract: A lead frame material comprises a base plate consisting of copper or copper alloys, and a protective coating formed on the upper or the both surface of the base plate. The protective coating is composed of at least one metal selected from the group consisting of gold, gold alloy, silver, silver alloy, palladium and palladium alloy, and has a thickness of 10-500 angstrom. The protective coating is formed by means of vapor deposition. It is possible to form an intermediate coating of nickel or nickel alloys between the surface of the base plate and the protective coating, by means of vapor deposition or wet plating. The suitable thickness of the intermediate coating is within the range of 50-20000 angstrom.

Abstract: A method of making a strip product having a surface that is both bright and clean after being rolled by work rolls in a roll stand. The work rolls are polished to remove grind lines from the roll surfaces, and the roll surfaces are provided with minute, ovoid depressions having relatively shallow slopes extending in the direction of rolling, followed by steeper slopes at the opposite ends of the depressions. The depressions are created by a laser beam directed against the roll surfaces at oblique incidence to the roll surface normal during relative movement of the beam and roll surfaces. The roll surfaces are then polished to remove any roll material that is raised above the nominal surface of the rolls, the raised material being the result of melting of the roll surfaces and the deposition of roll material vaporized by the laser beam.

Abstract: A long-life, inexpensive rotary anode for use in an X-ray tube having an X-ray generating layer formed by CVD on a graphite substrate and capable of producing high-power X-rays without the possibility of thermal cracks or delamination. When forming the X-ray generating layer of a tungsten-rhenium alloy on the graphite substrate through a rhenium intermediate layer by CVD, material gases are supplied intermittently so that the entire part or only the surface area of the X-ray generating layer will be formed of laminated structure of ultra-thin films each 0.1-5.0 microns thick. The content of rhenium in the tungsten-rhenium alloy forming the X-ray generating layer has a gradient form, i.e. increases from the interface with the rhenium intermediate layer toward the surface, so that the total amount of rhenium added can be reduced.

Abstract: The article is constituted from a plate produced from a relatively soft first metal (1). It has, on one of its faces, a metallic element (2) in the form of a perforated sheet or a grid produced from a second metal or alloy harder than that of the plate (1). The metallic element (2) is fixed to the plate by drop-forging or stamping in order to embed it, at least partially, in this plate. The article is especially useful as a cooking vessel.

Abstract: A slide surface construction which is an inorganic skin film formed of an aggregate of Fe crystals having a body-centered cubic structure. The aggregate includes a large number of {222} oriented Fe crystals with their {222} planes (by Miller indices) oriented toward a slide surface. At least some of these {222} oriented Fe crystals are hexangular pyramid-shaped Fe crystals having six ridge lines. These Fe crystals having six ridge lines ensure that the oil retention of the slide surface construction can be improved, and a slide load acting on the slide surface can be finely divided.

Abstract: The invention relates to a material in the form of a strip having a stiffening corrugation thereon. The corrugation consists of ridges and valleys therebetween which form arcs over the breadth of the corrugation zone. The corrugations form a wave pattern propagating in the longitudinal direction of the strip. The waves have no straight sections, and the relationship between the thickness of the strip T and the corrugation depth A is 0.5T<A<2T. In addition, the height of the arcs is at least as large as the wave length of the waves propagating in the Y-direction and alternating in the Z-direction.

Abstract: A vacuum insulated panel having high thermal insulating value and long vacuum life, and a method of making such a panel are disclosed. The panel is formed of peripherally welded metal wall members which define a cavity within which, in one embodiment, a compressed block of particulate material is disposed. The particulate material, in this embodiment, serves as a barrier to radiant thermal transmission through the panel, acts as a getter to maintain the vacuum in the panel, and supports the walls of the panel against collapse when the cavity is evacuated. The vacuum insulated panel can be covered with a polyurethane foam insulating material. According to a further embodiment of the invention, the filler within the cavity is a sandwich comprising a compressed layer of particulate material suspended between two layers of fiberglass.

The result is a surface quality which can be separately influenced by the composition of the alloy of the glass-metal film (1). The object may be formed either as a parting tool or as a structural part with special wear and/or sliding properties.
