Abstract: A binder composition for producing articles of bonded particulate material such as foundry moulds or cores comprises an alkaline aqueous solution of a resol phenol-aldehyde resin and an oxyanion capable of forming a stable complex with the resin the amount of alkali present in the solution being sufficient to sub­stantially prevent stable complex formation. Bonded articles are produced from mixtures of particulate material and the binder composition by passing carbon dioxide gas through the formed articles whereby the oxyanion forms a stable complex with the resin and the resin is cured. The oxyanion may be for example borate, stannate or aluminate.

Abstract: To date, highly porous ceramic materials have been infiltrated with a metal melt so that the product produced therefrom has a predominantly metallic structure. This ceramic-metal composite (CMC) is substantially metal-like in its properties, so that the requirements with regard to hardness, heat stability and wear are well below the values of the purely ceramic materials. The properties of the ceramic materials with regard to flexural strength, toughness, modulus of elasticity, hardness and resistance to wear are to be improved while retaining or increasing the properties such as hardness, temperature behaviour and resistance to wear, which are superior compared with metallic materials. The metal-ceramic composite is characterised in that the ceramic is composed of several layers, the layer thickness being between 10 and 150  mu m and the mean pore radius between 100 and 1000 nm with a final open porosity of 5-14% and a total porosity of 5-30%, and the metal fills the pore volume except for a residual pore volume of 0.1 to 10%, based on the initial porosity. The ceramic-metal composite is preferably used for binding to metal structures, such as welded or soldered ceramic/metal constructions.

Abstract: A method of forming a composite surface which is comprised of a base or primary surface and a number of features, and which satisfies certain functional objections. Implemented in a CAD system employed to assist in the design of automobile inner panels, the method accepts as input feature-based information which describes the geometry of a particular inner panel, and produces as an output a composite surface with a user-specified degree of smoothness. The method permits interactive design and modification of complex inner panel surfaces, and which significantly simplify attendant aspects of the panel design process such as NC-machining.

Abstract: Methods and apparatus are described for determining the curvature of a surface by use of multiple discrete triangulation sensors are described. Robustness in the face of an extreme manufacturing environment is achieved by placing a triangulation light source (26; 78) and a detector (30; 82) at a remote, environmentally controlled location. Light is relayed from the remote source to each sensor head (28; 70, 72, 74) by a single mode optical fiber (36; 76), which then projects a spot (L onto the surface (S under consideration. An image of the spot is formed in each sensor head, and is relayed back to the remote detector by a coherent bundle of fibers (50; 62; 80). Range to the surface at each sensor head is inferred by the position of each image as relayed by the coherent bundles, while curvature of the surface is determined by comparing ranges as measured at each sensor head. The optics contained in each sensor head are adapted to work well with specular, diffuse, opaque or transparent surfaces.

Abstract: A method of shimming a magnet having correction (shim) coils (3) is provided. The field strength in the bore of the magnet is measured at a predetermined number of points (13). The field inhomogeneity is determined from the measured field strengths. The field created by a fixed current in each shim coil operating alone, at each of the predetermined points, is determined. The shim correction coil currents are determined using a linear programming solver to minimize the field inhomogeneity and the correction coil currents. The correction coil currents are determined based on the measured field in the bore of the magnet and the field created by each of the shim coils when carrying a fixed current, with the correction coil currents each constrained to a maximum value which is adjusted for the current in the correction coils when the field strength was measured. The correction coils are adjusted to the determined values and the field strength of the magnet is again measured at the predetermined points. The inhomogeneity is again determined and compared to a desired value of inhomogeneity. If the inhomogeneity is greater than desired, then shim correction coil currents are again determined, the determined shim coil currents set, and the field measured until the desired inhomogeneity is achieved.

Abstract: A system (70) and a method for removing sludge and debris from the interior of the secondary side (5) of a nuclear steam generator (1). The method comprises the steps of introducing a sufficient amount of water in the secondary side (5) to submerge at least the tubesheet (7), generating a succession of shock waves in the water by means of pulses of pressurized gas to create shock waves that loosen the sludge and debris, and vertically flushing the interior of the secondary side (5) by suctioning water off from the bottom portion of the steam generator (1) while simultaneously forcefully spraying water from the top portion of the generator (1) over the bundle (20) of heat exchanger tubes (22) in order to remove the sludge and debris loosened by the shock waves. To conserve the water used in the flushing operation, the water that is suctioned off from the bottom portion of the steam generator (1) is filtered and deionized and reintroduced through hoses (128a, 128b) at the top portion of the generator (1) which forcefully directs water downwardly through the bundle (20) of heat exchanger tubes (22) and against the tubesheet (7). The invention greatly enhances the effectiveness of pressure pulse, water slap and water cannon cleaning methods in the secondary sides (5) of nuclear steam generators (1).

Abstract: A metal surface is now described having enhanced adhesion of subsequently applied coatings. The substrate metal of the article, such as a valve metal as represented by titanium, is provided with a highly desirable surface characteristic for subsequent coating application. This can be initiated by selection of a metal of desirable metallurgy and heat history, including prior heat treatment to provide surface grain boundaries which may be most readily etched. In subsequent etching operation, the surface is made to exhibit well defined, three dimensional grains with deep grain boundaries. Subsequently applied coatings, by penetrating into the etched intergranular valleys, are desirably locked onto the metal substrate surface and provide enhanced lifetime even in rugged commercial environments.
