Title: Procede utilisant une membrane pour eliminer la vapeur d'eau contenue dans des gaz
Inventor: OVERMANN DANA C III
IPC: B01D53/26
Filed: 1990-11-30
Abstract: Le procédé permettant d'éliminer la vapeur d'eau contenue dans des gaz consiste à mettre en contact un mélange de gaz d'alimentation contenant de la vapeur d'eau avec une face (22) d'une membrane semi-perméable (20) sélectif pour le passage de la vapeur d'eau. Un différentiel de pression partielle de la vapeur d'eau est maintenue sur une membrane (20) dans des conditions telles que la vapeur d'eau passe à travers la membrane (20) du côté haute pression (22) vers le côté basse pression (24) de la membrane (20). Le côté opposé basse pression (24) est en contact avec un gaz de balayage sec et condensable dont l'alimentation se fait par un conduit (14), et qui est récupéré et condensé, provoquant ainsi la séparation du gaz de balayage contenant l'eau de perméation en une phase liquide organique et en une phase liquide aqueuse.

Title: Procede d'application d'un marquage indiquant l'orientation du reseau cristallin d'une tranche cristalline
Inventor: STECKENBORN ARNO
IPC: H01L23/544
Filed: 1991-06-04
Abstract: Pour la fabrication de structures tridimensionnelles en matériau semi-conducteur monocristallin, il est nécessaire de connaître l'orientation du réseau cristallin. On utilise à cet effet des marquages sur des tranches cristallines, qui sont constitués jusqu'à présent par un à-plat. Pour créer un marquage qui indique avec une très grande précision l'orientation du réseau cristallin d'une tranche cristalline, la tranche cristalline (3) est exposée à un rayonnement X (30) dans le sens vertical ou, au niveau d'un emplacement rugueux (10) de faibles dimensions, au rayonnement (6) dans le sens vertical d'un laser d'orientation (5). Le rayonnement réfléchi (7) est détecté par une caméra vidéo (9) et des signaux électriques de la caméra vidéo (9) correspondant au rayonnement réfléchi (7) sont analysés dans un ordinateur (12) avec détermination de l'orientation du réseau cristallin. En fonction de l'orientation du réseau cristallin ainsi déterminée, on procède à un alignement des tranches cristallines (3) et d'une installation de marquage (15...20) et le marquage est appliqué sur la tranche cristalline (3) en position alignée. L'invention s'applique à la fabrication de composants pour la micromécanique.

Title: METHOD OF ISOLATING RESTRICTION FRAGMENT DELETIONS IN -i(VIBRIO CHOLERAE), AND PRODUCTS THEREOF.
Inventor: KAPER JAMES B
IPC: C12N1/21
Filed: 1991-06-05
Abstract: This invention relates to methods of isolating deletion mutants of Vibrio cholerae. In one method, the deletion is predetermined by digestion with restriction endonucleases of known specificity. The deletions are inserted into the Vibrio cholerae chromosome by in vivo recombination between a plasmid carrying the desired deletion, with adjacent flanking sequences, and the Vibrio cholerae chromosome. In another method, an initial in vivo recombination event of homologous sequences from the recombinant plasmid into the chromosome provides a selectable marker at this site. A second in vivo recombination event between homologous flanking sequences results in excision of proficient genes from the chromosome with the end product being a deletion mutation. The invention includes the isolation and characterization of a new Vibrio cholerae strain having a deletion in the ctx gene, as defined by Acc I, Xba I, Cla I and/or restriction endonuclease sites and further having a deletion in the gene encoding zonula occludens toxin.

Title: Engineered cementitious contaminant barriers and their methods of manufacture.
Inventor: JENNINGS HAMLIN M
IPC: G21F9/34
Filed: 1991-07-19
Abstract: Novel engineered cementitious contaminant barriers and containers for storage of hazardous waste are formed by positioning a hydraulic cement composition into a predetermined configuration and then hydrating the cement composition. One or more liquid, ion, or gas getters capable of binding with or absorbing liquids, ions, or gases which may penetrate the barrier may be positioned into the configuration before hydrating. The contaminant barriers of the present invention may be engineered to include mixtures of different getters, single and multiple layers of different getters, multiple layers of cement and getters, and a host of different getter, cement, mixture, and layer combinations. Novel waste containers are also advantageously prepared utilizing contaminant barriers within the scope of the present invention. The waste containers may be prepared by surrounding waste material with at least one getter and with a powdered hydraulic cement composition and then compressing the cement and getter around the waste material. Preformed waste containers may also be prepared within the scope of the present invention. Use of reinforcing fibers and aggregates to improve the mechanical properties of the hazardous waste container is disclosed.

Abstract: A noise protection wall (1) with a relatively narrow base but sufficient height and advantageous stability consists of individual rectangular wire-mesh baskets which are in turn assembled from longitudinal and transverse walls which are interconnected in an articulated manner. The transverse walls are in this case provided with hooks assigned to the horizontal bars and have vertical bars projecting beyond the lowest horizontal bar so that they can be pushed onto one another or into one another or pushed onto corresponding support elements. The longitudinal walls (3, 4), which after suspension in the transverse walls form an outwardly directed bulge or curve, are then connected, by bending over the hooks, to the transverse walls which are themselves already erected and stabilised. For stabilising, use is in this case made of a reinforcing element, usually in the form of an L-shaped profile, which in each case connects two transverse walls and which is arranged with the angle upwards so that earth cannot collect. This individual stable wire-mesh basket is connected to corresponding further wire-mesh baskets, the transverse walls in each case being placed or pushed onto one another so that a very stable overall construction is produced, into which the earth can subsequently be filled. Compaction is as a rule not necessary so that such an earth wall or because a corresponding noise protection wall can be erected with relatively low outlay. <IMAGE>

Abstract: Routing system for, for example, items of mail. At the beginning of the routing system (RS), the address (a) is converted into an electronic code signal (c1). Said code signal can be changed and/or supplemented from the outside by means of parameter signals (p), resulting in a converted code signal (c2). The system achieves the result that the delivery of items of mail can be influenced 'on line', i.e. the address, ('follow me' mail), the time or the form or manner of delivery. On-line information (i) can also be obtained on items of mail (for example their status).
