Abstract: "PROCESS FOR CLEANING A PACKED COLUMN"                 Abstract of the Disclosure A process is disclosed for the cleaning of a clogged packed column.  The packed column is utilized for gas cleaning in a scrubbing operation carried out with a scrubbing medium, and becomes plugged by deposits which form during operation.  In order to be able to effectively and economically break up these deposits, the packed column is flooded, e.g., with a scrubbing medium, wherein the flooding fluid has a specific gravity greater than that of particles of packing material.  During the flooding of the packing, the deposits are broken up by flotation of the packing material.  Preferably, the packed column can thus be utilized in scrubbing out H2S in an oxidative scrubbing process in which sulfur deposits form.

Abstract: Human interferon-beta2A and interferon-beta2B are produced in purified form by recombinant DNA techniques. Two separate human genes have been identified which code for the production of IFN-.beta.2A and IFN-.beta.2B, respectively. The sequence of IFN-.beta.2A cDNA is established. These genes and cDNA have been cloned into mammlian cells with an SV40 early promoter sequence and such genomic clones are capable of pro-ducing IFN-.beta.2A and IFN-.beta.2B. The antaviral activity of such recombinant IFN-.beta.2A and IFN-.beta.2B is demonstrated as well as other biological activity identifying them as human interferons. It has been shown that IFN-.beta.2 secretion is induced in human cells by growth-stimulatory cytokines.

Title: Micro-capsules
Inventor: EKMAN BO M
IPC: B01J13/02
Filed: 1986-10-15
Granted: 1991-07-30
Abstract: ABSTRACT OF THE DISCLOSURE      The invention relates to a completely novel type of micro-capsules, viz. such capsules where an encapsulated hydrophobic or lipophilic substance is surrounded by polar solid crystals of polar lipids which expose their hydrophilic face outwards and their hydrophobic face turned inwards to-wards the hydrophobic or lipophilic substance. These micro--capsules can be utilized to encapsulate for instance tacky substances or substances to be protected against oxidation or influence from light. Moreover, an especially interesting use according to the invention is the use of said micro-capsules in an ointment base, where the active ingredient is well pro-tected within said capsules up to the use but which at the application on the skin directly comes into contact with the skin surface as a consequence of the crystalline structure of the shell. Furthermore, the invention relates to a special micro-capsule composition in the form of a dispersion of said micro-capsules in water or a polar liquid, where the crystals constitute 5-50 percent by weight and water or the polar li-quid 50-95 percent by weight. Moreover, the invention relates to a process for the preparation of said micro-capsules, wherein a mixture of said polar lipid with water or polar liquid is formed, the mixture is heated above the transition temperature of the lipid and the mixture is then cooled to the desired temperature so as to obtain crystallization, the hydrophobic or lipophilic substance being added before or during the liposomic phase. Finally, the invention relates to a crystal dispersion of the polar lipid in a polar liquid, such as glycerol, ethylene- or propylene glycol.

Abstract: ABSTRACT OF THE DISCLOSURE        An expert information system with which a decision maker in the construction, or a related industry, can generate a decision record and related control instructions in a facile manner without significant omissions while ensuring that substantially all of the options available for making the decisions have been considered.  The expert system includes a microcomputer which executes a system control program to select information units from the expertise of a data base and to concentrate individual information units until an entire decision record has been generated.  The process is enhanced by a multiwindowed display which displays possible selections from the expert data base while contrasting that data with data in another window having a list of data indicating the decisions or selections already made.  A display pointer with a controllable position is employed to select lines and phrases of the expert information from that portion of the data base displayed in the selection window.  The selection of such information causes the line or phrase from the data base, an information unit, to be transferred to the decision record and to the display of the selected decisions window.

Abstract: Abstract of the Disclosure Fragments of a biopsy sample on the order of about 50 to 5000 cells are preferred for establishing viable tumor cell cultures for purposes such as establishing cell lines, chemotherapeutic assays and the like.  Such fragments retain the three-dimensional cellular structure or organization of the original tumor and, therefore, can be cultured more readily.  To obtain such fragments suitable for culturing, the biopsy sample can be enzymatically digested in a proteolytic or nucleolytic enzyme, such as collagenase, or by mechanical dissociation, or both where necessary.  The fragments can then be suspended in an aqueous medium so that non-aggregated cells (e.g., red blood cells, lymphocytes, macrophages) and cellular debris will form a supernatant while the remaining fragments containing aggregated tumor cells are deposited in a sediment layer.  Preferably, the medium is an isotonic tissue culture medium and decantation is conducted at least twice; first in a serum-containing medium and then, secondly, in a serum-free medium.  Fragments containing living tumor cells can be selected by fluorochsomasia, that is, by contacting the sedimented layer with a fluorogenic substrate such that viable tumor cells take up and hydrolyse the substrate, and then exhibit fluorescence.          Cytotoxicity assay protocols employing tumor cell aggregates prepared by the present techniques are also disclosed.
