Abstract: Complex metal structures are formed in microminiature dimensions utilizing multiple mask exposures which are capable of producing substantially arbitrary three-dimensional shapes. A first layer of a primary metal is electroplated onto an exposed plating base to fill a void in a photoresist, the photoresist is removed, and a secondary metal, which can constitute a sacrificial metal, is electroplated over the first layer and the plating base. The exposed surface of the deposited secondary metal is then machined down to a height which exposes the first metal to produce a substantially flat, uniform surface extending across both the primary and secondary metals. The secondary metal facilitates machining of the primary and secondary metals because of these mechanical stability provided by the secondary metal to the primary metal. After the first layers of the primary and secondary metals have been machined, another photoresist layer can be applied over the primary and secondary metals, and a second layer of primary metal is electroplated. A further layer of secondary metal can be also electroplated if desired. The process of machining and electroplating can be repeated until the desired structure is formed. Secondary metal is removed by an etchant which does not etch the primary metal.

Abstract: The invention relates to a process for separating HF contained in liquid mixtures comprising HCFC 123 and/or 124. The mixtures, enriched in C2Cl4 up to a content of such compound of 20-75% by weight, is subjected to a treatment for separating liquid phases, thereby obtaining an acid phase very rich in Hf and an organic phase impoverished in HF, which is subjected to a flash, so obtaining a liquid phase containing 123, 124 and C2Cl4, having a very low HF content, and a gas phase enriched in HF. As an alternative to flash, a separation in a distillation column can be carried out.

Abstract: This invention provides a urethane polymer finish for textile fabrics utilized in window coverings such as pleated shades and vertical blinds. This finish for window coverings such as pleated shades and/or vertical blinds includes a urethane polymer made from a diisocyanate and either a polyester or a polyether soft segment. The diisocyanate may be either aromatic or aliphatic with an aliphatic diisocyanate preferred to prevent yellowing. The combination of these ingredients are is either carboxylated or emulsified and then neutralized. This urethane polymer may optionally include a halogenated moiety and such as a brominated monomer. Although a one hundred percent urethane polymer finish is preferred, the actual percentage of urethane polymer in the dried finish on the textile fabric may be as low as forty-five percent and still achieve some of the significant qualities of this urethane polymer finish. Some of the these significant qualities of this urethane polymer finish include shape retention, high softening point, flame retardancy, non-blocking, stiffness, non-yellowing and light fastness. <IMAGE>

Abstract: The present invention provides compositions and methods for isolating nucleic acids with lengths greater than about 50 bases, from cells, gels, solutions and other media, in which nucleic acids occur in vivo or in vitro. The compositions of the invention are mixtures of the silica materials silica gel and glass particles, particularly glass microfibers; such mixtures combined with chaotropic salts, such as guanidinium chloride or guanidinium thiocyanate; and suspensions of such mixtures in aqueous solutions of chaotropic salts. In the methods of the invention, an aqueous solution comprising nucleic acid is mixed with an aqueous solution of chaotropic salts and the resulting solution is contacted with a mixture of the silica materials, whereupon the nucleic acid in the solution binds to the silica materials. The chaotropic salts and components, other than the nucleic acid adsorbed to the silica materials, from the aqueous solution treated by the method of the invention are washed from the silica materials. Finally, the nucleic acid can be obtained by elution from the silica materials. The methods provide nucleic acid in water or buffer, such as TE buffer, free of contamination by any salt or macromolecule that would interfere with further processing or analysis.

Abstract: Lithographic printing constructions and methods of imaging them[ are disclosed]. The constructions include a grained-metal substrate, a protective layer that' can also serve as an adhesion-promoting primer, and an ablatable oleophilic surface layer. In operation, imagewise pulses from an imaging laser interact with the surface layer, causing ablation thereof and, probably, inflicting some damage to the underlying protective layer as well. The imaged plate may then be subjected to a solvent that eliminates the exposed protective layer, but which does no damage either to the surface layer or to the unexposed protective layer lying thereunder. <IMAGE>
