Title: Industrial filtration apparatus and method for the separation of solids from a fluid stream.
Inventor: CLOUGH GEORGE FRANCIS GILBERT
IPC: B01D33/01
Filed: 1991-08-21
Abstract: Industrial filtration apparatus for the separation of solids entrained in a fluid stream comprises: a flexible perforate filtering sleeve closed at one end such that fluid can pass through perforations in the sleeve but entrained solids of a predetermined size are retained within the closed end of the sleeve. The apparatus has a structure for holding the sleeve about a discharge pipe for the fluid at a point between the closed and open ends of the sleeve, and for restraining movement of the sleeve away from the pipe; the apparatus is adapted such that in response to a predetermined fluid (e.g. hydraulic) pressure within the sleeve between its closed end and the discharge pipe, the closed end is allowed to be displaced away from the discharge pipe, thereby drawing a portion of the sleeve nearer its open end into a position forward of the pipe to expose said portion to the fluid stream.

Abstract: L'invention concerne les lasers, et tout particulièrement les lasers à l'état solide tels que les lasers au néodyme sur cristal de niobate de lithium. L'invention propose une structure à plusieurs guides optiques juxtaposés (12), suffisamment proches latéralement les uns des autres pour être couplés latéralement. Pour tenir compte des risques d'inhomogénéité d'indices de réfraction, ou imprécisions de dimensions qui altéreraient la répartition du champ électromagnétique du supermode de propagation de la structure couplée, on propose d'agir par une commande individuelle (en principe électrique) de la valeur de l'indice de propagation dans chaque guide. De la variation d'indice, commandée individuellement, il résulte des déphasages de l'onde laser entre les différents guides, et ces déphasages réagissent sur la composition de champs électromagnétiques définissant le supermode. On peut aller jusqu'à modifier la directivité du faisceau laser par cette commande électrique. La commande est faite de préférence par des électrodes (14) placées au voisinage de chaque guide. Les guides sont en matériau électro-optique tels que le niobate de lithium et le dopage au néodyme par exemple permet l'apparition de l'effet laser à l'intérieur même des guides.

Abstract: L'invention concerne un procédé de production d'un anticorps chimérique, dans lequel la région de détermination complémentaire (en anglais CDR) d'un premier anticorps est épissé entre les régions cadre d'un second anticorps. Ce procédé est réalisé au moyen d'une matrice comprenant deux régions cadre, AB et CD, et entre les deux le CDR qui sera remplacé par un CDR de donneur. Les amorces A et B sont utilisées pour amplifier la région cadre AB, tandis que les amorces C et D sont utilisées pour amplifier la région cadre CD. Cependant, les amorces B et C contiennent à leurs extrémités 5' une séquence additionnelle correspondant à tout ou du moins partie de la séquence de CDR du donneur. Les amorces B et C se chevauchent d'une longueur suffisante pour permettre la liaison de leurs extrémités 5' respectives dans des conditions permettant à une réaction en chaîne de polymérase (en anglais PCR) de se produire, de manière à incorporer l'ensemble de la séquence de CDR de donneur. Les régions amplifiées AB et CD peuvent être soumises à un allongement du chevauchement d'épissage pour produire en une seule réaction le produit chimérique.

Abstract: A dewatering device for the web-forming or wet section of a papermaking machine comprises foils arranged transverse to a forming wire, that is to say, extend in the cross-machine direction. Force or powering elements act upon the foils so as to exert a force or pressure upon the forming wire, and thus, bring about dewatering and sheet formation of a layer of fiber stock suspension reposing upon the forming wire. The force elements are constructed and positioned such that additional moments are generated which counteract tilting moments produced by the frictional force present between the foils and the forming wire. In certain arrangements, the force elements also can be interconnected with one another.

Abstract: In order to achieve, in a simple manner by galvanic precipitation of metal, a filter material having very small filter openings and a relatively large open surface area, the invention provides that an adhesive layer (2) is applied to a substrate (1), which layer is penetrated by an electrically conducting structure (2) (3). In the adhesive layer, electrically insulating and fibrous flock rods (4) are anchored by flocculation, after which metal is galvanically precipitated onto the flock-coated substrate, using the electrically conducting structure as a cathode. The metal coating (5) thus produced is then peeled off from the substrate, after which the adhesive layer and the flock rods are washed out with the aid of a solvent. The filter material thus obtained has a multiplicity of microchannels almost identical in diameter and can have a thickness which exceeds the nominal width of the microchannels by at least one order of magnitude.

Abstract: A 4-(1,1-dialkoxycarbonylalkyl)azetidin-2-one derivative is of the formula:
       
where R 1  and R 2  each represents alkyl, alkenyl or aralkyl (preferably both are 2-alkenyl), R 3  represents CI-4 alkyl, R 4  represents hydrogen or a hydroxyl-protective group, e.g., tri-substituted silyl, acyl or aralkyl, and R 5  represents a hydrogen atom or an amino-protective group e.g., tri-substituted silyl, aralkyl or alkoxyalkyl. Synthesis when R 5  is H is from a malonic acid derivative R 3- COOR I .COOR 2  and a 4-acetoxyazetidin-2-one derivative; and when R 5  is a protective group the thus produced compound is reacted,e.g. with a tri-substituted silyl chloride so as to incorporate such groups. 
     For synthesis of a 4-(1-carboxyalkyl)azetidin-2-one derivative (II)
       
where R 3  represents a CI-4 alkyl and R 4  represents hydrogen or a hydroxyl-protective group, the compound (I) is de-esterified and decarboxylated (I), and when an amino-protective group is present in (I), this group is then eliminated. 
     The products (II), especially those having a β-configuration alkyl group, are useful as an intermediate for 1β-alkylcarbapenem-type antibacterials and can thus be produced efficiently on an industrial scale.
