The present invention relates to agglomerated zeolitic adsorbents based on zeolite X with an Si/Al ratio such that 1.15<Si/AL<1.5, consisting of crystals with a mean diameter of 1.7 mm or less and of an inert binder, at least 90% of the exchangeable cationic sites of the zeolite X being occupied by barium ions. They may be obtained by agglomerating a zeolite X powder having a mean diameter of 1.7 mm or less with a binder, followed by zeolitization of the binder, exchange of the zeolite ions with barium (and potassium) ions and activation of the adsorbents thus exchanged. These adsorbents exhibit, simultaneously, excellent selectivity, reduced mass transfer resistance and excellent mechanical strength and are particularly suitable for the adsorption of the paraxylene contained in C8 aromatic hydrocarbon fractions in liquid phase in processes of the simulated moving bed type and especially for the separation of paraxylene of C8 aromatic hydrocarbon fractions by adsorption, but also for the separation of sugars, polyhydric alcohols, cresols, and substituted toluene isomers.

We have discovered that the formation of particulate inclusions at the surface of an aluminum alloy article, which inclusions interfere with a smooth transition from the alloy surface to an overlying aluminum oxide protective film can be controlled by maintaining the content of mobile impurities within a specific range and controlling the particulate size and distribution of the mobile impurities and compounds thereof; by heat-treating the aluminum alloy at a temperature less than about 330° C.; and by creating the aluminum oxide protective film by employing a particular electrolytic process. When these factors are taken into consideration, an improved aluminum oxide protective film is obtained.

A continuous electroforming process to form a strip for battery electrodes, comprising the steps of providing a mandrel having on its surface a reusable pattern subdivided into conductive and non-conductive areas; moving said mandrel through an electroforming bath to deposit a metal layer on said mandrel while it moves through the electroforming bath until the metal layer has assumed the shape of the conductive pattern and a thickness at least sufficient to provide strength for the layer to be removed from said mandrel; and separating said layer from said mandrel; is characterised by moving said strip through at least one subsequent bath in which electrodeposition of metal takes place on both sides of said strip while it is moved through said subsequent bath, applying a current density of at least 10 A/dm2 and up to 300 A/dm2 to the conductive surface of the moving mandrel and to the metal surface of the strip in each of the subsequent baths; and directing a forced flow of electrolyte onto the surface of the layer and said strip, wherein the reusable conductive pattern of the surface of the mandrel takes the form of at least one battery electrode and the electrolyte contains additives providing increased hardness, increased corrosion resistance and being suited specifically to permit combining a high rate of deposition with controlled surface roughness and controlled composition of the deposit.

A bonded wafer structure having a handle wafer, a device wafer, and an interface region with an abrupt transition between the conductivity profile of the device wafer and the handle wafer is used for making semiconductor devices. The improved doping profile of the bonded wafer structure is well suited for use in the manufacture of integrated circuits. The bonded wafer structure is especially suited for making radiation-hardened integrated circuits.

The invention discloses a method for producing high-salinity maritime work cement through mineral waste residue waste materials. The high-salinity maritime work cement is prepared from, by weight, 30-40 parts of mineral waste residues, 40-50 parts of sulphate aluminum cement clinker, 0.03-0.05 part of composite activating agents, 2-4 parts of early strength agents, 0.3-0.5 part of water reducing agents, 0.005-0.007 part of air entraining agents and 0.3-0.5 part of retarder. The method for producing the high-salinity maritime work cement comprises the steps that the mineral waste residue waste materials, the sulphate aluminum clinker, the composite activating agents and the early strength agents are smashed, ground into powder and homogenized respectively and then dosed, mixed and homogenized according to proportions, then the water reducing agents, the air entraining agents and the retarder are added, mixed and homogenized, and the product is obtained. The high-salinity maritime work cement has the performance of common cement, further has the excellent characters of early-stage hardness resisting, long-term corrosion resistance, retardation progressive increasing and the like, and is especially suitable for ports, wharfs and other engineering which are corroded by corrosive media.

A workpiece is irradiated by a laser beam scanned in an oscillating track as the workpiece is advanced along a feed path in a hardening process. Sinusoidal variations in scan velocity are offset by decreasing the laser beam power level at phases in the scanning cycles corresponding to high and low scan displacement peaks, where the scan velocity is least. The beam power is increased near the scanning center line where the scan velocity is highest. The beam energy applied per unit of area is thus equalized over the scanning cycle. The workpiece temperature can be sampled at regular phases by a non-contact temperature sensor in the optical path, and used to control beam power versus phase in a subsequent scanning cycle. Alternatively or in addition, a sinusoidal beam power pattern can be stored and used to offset scan velocity variations as a function of phase.
