Title: Method of gene transfer using retrotransposons
Inventor: HODGSON CLAGUE PITMAN
IPC: C12N15/63
Filed: 1991-10-25
Abstract: A process for the transfer and/or expression of any gene into cells, organisms or species is disclosed. The process involves isolating the gene, introducing the gene into a vector comprised of at least one retrotransposon genetic element to provide a hybrid gene. The hybrid gene is introduced into a donor cell capable of packaging and transmitting the retrotransposon to other cells, organisms or species. The hybrid gene is transferred to a recipient cell wherein the hybrid gene replicates by reverse transcription and is inserted into the recipient cell's genome. The gene is preferably expressed as RNA and/or protein, giving the phenotype of the gene.

Abstract: In this process, a fly ash, precipitated in the dry state from the crude partial oxidation gas produced, is mixed with the fuel at the inlet of the common proportioning vessel (5) in a specially constructed mixing station (26), whereupon the resulting mixture is introduced into the gasification reactor (16). In this case, the volumetric flow of carrier gas fed to the proportioning vessel (5) is adjusted such that this volumetric flow is sufficient exclusively for covering the requirement for maintaining the pressure in the proportioning vessel (5) and for conveying the fuel/fly ash mixture from the proportioning vessel (5) to the gasification reactor (16) and that there is no loosening, similar to a moving bed or fluidised bed, of the fuel/fly ash mixture either in the proportioning vessel (5) or in the lines leading from the proportioning vessel (5) to the burners (15) of the gasification reactor (16). <IMAGE>

IPC: C01G23/053

Abstract: The titanium dioxide is essentially transparent to visible light and essentially absorbent for UV radiation. In its preparation, finely divided tin dioxide with a particle size of from 1 to 10 nm, preferably from 1 to 4 nm, is employed in an amount from 0.5 to 10 per cent by weight, based on TiO2. The addition of tin dioxide establishes the particle size of the titanium dioxide at the desired value. Conditioning at from 300 to 800 DEG C, preferably from 400 to 600 DEG C, causes rounding of needle-like particles. The particles can be coated with inorganic and/or organic substances by an aftertreatment. Finely divided titanium dioxide can be prepared from sodium titanate by decomposition using hydrochloric acid or by suitable hydrolysis of a compound of tetravalent titanium, which results in rutile formation. The tin dioxide is preferably employed as a colloidal solution formed by reaction of tin tetrachloride with water at a maximum of 22 DEG C.

Abstract: A method for obtaining quantitative compositional information from a multilayer web containing a highly light-scattering component. The compositional information is obtained by measuring and analyzing the transmitted or diffusely reflected infrared spectrum. The method allows for separately determining the moisture content of hydrophobic (non-hydrogen bonding) layers and hydrophilic (hydrogen bonding) layers of multilayer webs. The separate measurements of moisture content can be made simultaneously in moving webs having both types of layers present. The method is used to determine further compositional information such as the thickness of the individual support and gelatin containing layers, plasticizer content, retained solvents content, and the presence of other components in webs, especially photographic webs.

Abstract: An outside mirror for a motor vehicle is described, which has a mirror base (2) on which a mirror casing (10) is attached so as to be pivotable about the axis (32) of a tubular rivet (30) which connects the mirror casing (10) to the mirror base (2) in a spring-loaded fashion, a locking body (50) which is penetrated by the tubular rivet (30) being held between the mirror base (2) and the mirror casing (10) and locking elements (52,56,58) which releasably engage into one another being formed on an end surface of the locking body (50) and on an adjacent part of the mirror base (2) or mirror casing (10). In order to make it unnecessary to provide a slot on the transition between the outside surfaces of the mirror casing (10) and on the mirror base (2), which slot permits swivelling of the mirror casing (10) and leads to the generation of wind noise during rapid travel, the locking body (50) is held in the mirror casing (10) or in the mirror base (2) in a non-twistable fashion and is axially movable relative to the mirror casing (10) and at the same time relative to the mirror base (2). <IMAGE>

Abstract: A probe head (10) includes a support (12) by which the probe head is retained on the quill of a coordinate positioning machine, and a rotor (14) which is magnetically retained on the support (12). The rotor (14) is rotatable between a plurality of indexed angular positions provided by a ring of balls (26) and three adjacently positioned pairs of rollers (24). A drive dog shaft (20) is linearly movable to disengage the balls (26) from the rollers (24), and rotatable to rotate the rotor (14) to a new indexed position, whereupon the drive dog shaft (20) is retracted to re-engage a set of three balls (26) with the rollers (24). Exchange of a measuring probe (16) is performed by removing the entire rotor (14), and exchanging it for a further rotor carrying a different measuring probe. The engagement elements provided by rollers (24) and balls (26) thus serve the functions of (a) indexing and (b) repeatably retaining a rotor (14) on the support (12). This reduces the number of kinematic locations required between the movable arm of the machine and the probe (16) during the course of normal operation of a probe head to which a number of probes (16) are releasably couplable.

Abstract: Each drawing train (1) alternately feeds two spinning cans (A, B). When changing the can, the yarn is cut and its end is hooked onto a storage bobbin (16A, 16B). A carriage (23), which is displaceable along a slide (C), supports in particular a yarn suction arm (25) mounted pivotably about an axis (26), a joining device (28), a winding system with yarn reserve (31), and a bobbin (32). The carriage (23) is displaced opposite the storage bobbins (16A, 16B) of different centrifugal spinning systems associated with several drawing trains. The winding system with yarn reserve is intended to ensure the continuity of the winding of the yarn on the bobbin (32) during the displacement of the carriage, and the joining of two yarn ends by means of the joining device (28), in such a way that a continuous yarn is produced on the bobbin (32), wound on at a speed which is a multiple of the speeds of each drawing train. <IMAGE>

In the preferred embodiment (Fig. 2) the flex dividers (30) are constructed with at least one vertical lower section (30L) joined to at least one upper section (30U) by memory flex means (36). The memory flex means (36) tends to hold the upper section (30U) in an open or more vertical position when there is no load on the upper section, or to return the upper section toward the more vertical position when a load, holding the upper section in a closed or more horizontal position, is removed. The flex means may be a curved sewn line so that the upper divider section is curved when under load. 
     In an alternative embodiment (Fig. 9) the dividers are Y-shaped.

Abstract: Selon un procédé de fabrication de pièces coulées à l'aide d'une machine à coulée sous pression (1), l'introduction dans une chambre de remplissage (9) du métal en fusion (6) contenu dans un réservoir (7) résulte d'une pression différentielle réglable entre les deux, le métal en fusion (6) étant pressé dans une cavité de moule (5) par un piston d'injection (14) situé du côté de la chambre de remplissage, après une phase de remplissage et de dosage.
