IPC: B01J45/00
Filed: 1979-02-08
Abstract: Ion exchangers based on polyamines, for example aminopolystyrene containing anchor groups of aminocarboxylic acids bonded directly to the polystyrene, have only low selectivity. Ion exchangers based on polyamines of the formula P-N-=N-R in which P is the radical of a polyamine and R is a polydentate group which forms chelate complexes with metal ions or anions, have high selectivity. They can be prepared by a process in which the polyamines are diazotised and reacted with couplable compounds which form, with metal ions or anions, chelate complexes which have high stability and rapidly come to exchange equilibrium. The preferred couplable compound is a polydentate chelating organic reagent, and the preferred polyamine is macroporous aminopolystyrene; the formation of phenolic hydroxyl groups during the coupling reaction is preferably suppressed by adding reducing agents. The ion exchangers according to the invention can be used to selectively remove certain metal ions or anions from aqueous or organic solutions, in particular for selective removal of trace elements present in seawater.

Abstract: A multiple vessel cascade gas enrichment adsorber is provided herein. A first stage adsorption vessel (13) is provided with a primary gas inflow means (12), a primary gas outflow means (32), and a mass of a suitable adsorbent material (36) in the vessel disposed between the primary gas inflow means (12) and the primary gas outflow means (32). At least one subsequent stage adsorption vessel (14) is provided in cascading interconnection with the first stage adsorption vessel (13) through an associated interstage loop line (15), each such subsequent stage adsorption vessel (14) being provided with a first gas inlet means (34), a first gas outlet means (30) and a mass of a suitable adso adsorption material (36) disposed between the first inlet means (34) and the first outlet means (30). The first outlet means (30) which is associated with the subsequent stage adsorption vessel (14) farthest downstream from the first stage adsorption vessel (13) is provided with an outlet back pressure regulator and non-return valve (24). Each such associated interstage loop line (15) includes a back pressure regulator and valve (23) therein. Secondary gas outlet means (18,19) lead to second secondary gas outlet lines (20) from each of the first stage adsorption vessel (13) and the subseqeunt stage adsorption vessel (14), each such secondary gas outlet means (18,19) including a plurality of vertically spaced-apart, horizontally extending collector means disposed within each such first stage adsorption vessel (13) and such subsequent stage adsorption vessel (14). Each such collector means is provided with a plurality of dispersed gas inlet ports. Diaphragm valves (21) are associated with each such collector means. Means actuate the diaphragm valves for alternate cyclical operation for a production period, defined as the period wherein the diaphragm valves are closed (to provide a long adsorption path from the primary inflow means to the first outlet means), and an evacuation period, defined as the period wherein the diaphragm valves are opened (to provide a short desorption path through the secondary outlet means). The individual volumetric size of the subsequent stage vessel or vessels must be smaller than the volumetric size of the first stage vessel. The cascading of the adsorbers significantly decreases the time required for regeneration by increasing the tolerance for residual adsorbate on the major portion of the adsorbent. Despite the cyclic nature of the process, the flow of product, e.g., oxygen is continuous.

Abstract: Die Erfindung betrifft eine Maske zur Abbildung eines Musters auf einer Photoresistschicht mit mindestens einer Justiermarke, einem Verfahren zur Herstellung einer solchen Maske und Verwendung dieser Masken zur Herstellung von Halbleiterbauelementen. Die Masken gemäß der Erfindung werden in der Weise erhalten, daß bei ihrer Herstellung die Muster benachbarter Chipfelder so abgebildet werden, daß sie sich in ihren Randbereichen, in denen die Justiermarken vorgesehen sind, überlappen. Bei dem Verfahren werden Justiermarken erhalten, die das Mittel aus mindestens zwei Justiermarken benachbarter Chipfelder darstellen. Mit dem genannten Herstellungsverfahren können die optisch mechanischen Abbildungsfehler, die während der Maskenherstellung auftreten, weitgehend eliminiert werden. Die erfindungsgemäßen Masken lassen sich bei ihrer Verwendung in Halbleiterprozessen genauer justieren als bisher bekannte Masken. In Fig. 3B stellt die eingezeichnete Trennlinie die Schnittfuge zwischen den zwei benachbarten Chipfeldern F2 und F3 dar. Bei idealen Verhältnissen liegt der Schwerpunkt der Justiermarke M, die durch Überlagerung der Justiermarken der Felder F2 und F3 zustandekommt, genau auf dem Schnittpunkt der Mitteltinie der Chipfelder mit der Schnittfuge oder Trennlinie. Das schraffierte Feld, das mit M F2, 3 bezeichnet ist und durch Überlagerung der entsprechenden Bereiche der Justiermarkenfelder M F2 und M F3 gebildet wird, ist die Justiermarke, die dem Operator später zur Justierung der Maske auf den Halbleiterwafer zur Verfügung steht.

Abstract: A process for preparing a feedstock capable of being converted into a deformable pitch containing an optically anisotropic phase employs an isotropic pitch or pitch-containing petroleum residuum. The aromatic oils content of the pitch is reduced by more than 40% by treatment under reduced pressure and/or stripping. A heat-soaking accompanies or follows the oils-removal. Heat-soaking is preferably at 350°C to 450°C for from 5 minutes to 10 hours. Preferably, thereafter, the product is treated with a solvent, or solvent mixture, having a solubility parameter at 25°C between 8.0 and 9.5. A solvent-insoluble fraction precipitates, which is thermally convertible into a deformable pitch containing over 75%of an optically anisotropic phase. The product is suitable for use in the manufacture of carbon artifacts, such as fibres, filaments and films.
