摘要:
An apparatus on a carding machine for processing textile fibres, with a cylinder, has, in the preliminary carding zone, after carding zone and/or underneath carding zone, covering elements which lie opposite the cylinder clothing. A fixed carding element is associated with at least one cover element. The spacing of the cylinder clothing from the clothing of the fixed carding element is smaller than the spacing from the cover element. In order to reduce nep formation, to allow improved carding work and to give a better carding result, between at least one clothing strip of the fixed carding element and a cover element arranged upstream and/or downstream thereof, there is arranged an air guide element the spacing of which with respect to the cylinder clothing gradually decreases or increases.

A light-alloy piston for internal combustion engine, is formed in the piston head with a combustion chamber recess. The stresses which are induced at the rim of the combustion chamber recess by the ignition pressure are reduced by the provision of an inwardly extending blind hole in the portions between the ring groove for the lowermost compression ring and the top apex of the bores in the piston pin bosses.

The invention relates to a flexible manufacturing system for the automatic processing of workpieces with a random number of subsequent processing stations, whereby fast adjustment to different workpieces is ensured. The workpieces are transported to the individual processing stations by a conveyor, where they are then processed by means of freely positionable processing tools.

An apparatus for gathering a running fiber web into a sliver, includes a web guide element having edge portions defining an outlet opening through which the web passes; a trumpet arranged downstream of the outlet opening of the web guide element as viewed in a direction of web advance, and an arrangement for guiding air, flowing against the direction of web advance and generated by web compression downstream of the web guide element, away from a zone extending between the outlet opening of the web guide element and the outlet opening of the trumpet.
摘要:
The present invention is directed to a bio-functionalized stimulus-responsive dissolvable PEG-hydrogel. This inventive stimulus-responsive dissolvable PEG-hydrogel comprises a matrix of PEG-polymers, which are modified to contain at least one multifunctional fusion protein, the multifunctional fusion protein preferably comprising as components a substrate binding peptide (SBP), preferably a repetitive RGD-binding peptide and/or a ZZ-binding domain, preferably a tag for purification, and at least one N- and/or C-terminal linker. The present invention is furthermore directed to the use of such inventive stimulus-responsive dissolvable PEG-hydrogels in the treatment of lesions, in surgical dressings, for wound treating, for soft and hard tissue regeneration, for the treatment of wounds in the oral cavity, in the field of ophthalmology, in the field of periodontal defects, etc. The invention also describes a method of treatment for such diseases. Additionally, the present invention provides a kit comprising the inventive stimulus-responsive dissolvable PEG-hydrogel and optionally further components.
摘要:
The invention relates to a pharmaceutical composition comprising a compound of formula (1) wherein R1 is optionally substituted phenyl, optionally substituted pyridyl or optionally substituted indolyl; R2 is (CH2)n wherein n is 0, 1, 2, 3 or 4; R3 is (CH2)mR3A wherein m is 0, 1, 2, 3 or 4, and R3A is methyl, isopropyl, tert-butyl, OCH3, OH, optionally substituted phenoxy, C≡CH, C≡N, optionally substituted phenyl, furanyl or thienyl; A is a ring containing X1 with the meaning O, S, NH, N(CH3) or CH2; and X2 is O, S or NH; and a compound of formula (2) wherein R4 is optionally substituted phenyl, optionally substituted pyridyl, optionally substituted indolyl, —NR7R8; or —NH—N═CH—R9; and substituents R5 to R9 have the meanings indicated in the description, in particular ethionamide. The pharmaceutical composition is useful, e.g., in the treatment of multidrug-resistant tuberculosis.
摘要:
The invention relates to microcapsules consisting of a polymer degradable by a polypeptide comprising a drug or other compound of interest and a genetically engineered cell expressing said polypeptide in response to a triggering compound, and to methods of directed release of the compound of interest. The preferred polymer is optionally modified cellulose sulfate/poly-diallyl-dimethyl-ammonium chloride. Such microcapsules are non-toxic, do not elicit an immunological response and have an extended half-life time in mammals. The expression system for cellulase is, for example, based on TET and doxycycline, or E.REX and erythromycin. In another example, expression of cellulase is triggered by luteinizing hormone, which can be used for artificial insemination with microcapsules carrying sperm.
摘要:
The present invention discloses mammalian cells useful for regulated gene expression in response to compounds being gaseous or liquid at the cultivation temperature of said mammalian cell, and non-human mammals comprising such mammalian cells. The invention further discloses methods for producing proteins in mammalian cells in a regulated way in response to inducing gaseous or liquid compounds. The invention is further directed to isolated nucleic: acids useful for constructing said mammalian cells.
摘要:
A device for superfinishing of ground surfaces of workpieces has a finishing block, which can be displaced by means of a drive device in a plane which is orthogonal with respect to the surface to be worked and is pivotable in this plane. By means of this it is possible to create a device of relatively small structural size, by means of which any arbitrary surfaces of workpieces can be treated.
