Abstract: The invention relates to an improved method for the accumulation and stabilization of DNA-containing components from biological materials, especially from blood samples. The DNA-containing sample materials are partially lysed in a lysis-binding buffer system, and the DNA-containing components, such as cell nuclei, are bound to a functionalized solid surface. The system comprises lysis reagents and solid adsorbents, the surfaces of the adsorbents being functionalized with polymers of polymerizable acids or derivatives thereof, to which the DNA-containing components bind. Organic or inorganic solid materials can be used as functionalizable carrier materials.

Abstract: An electric generation station employs a solar array to heat a thermal transfer fluid that is supplied to a heat exchanger to produce steam. The heated steam drives a steam engine that operates either an electric generator to produce electricity or a pump assembly. The pump assembly can pump water to an elevated location for use during peak times by flowing water downwardly past an electric generator. The electric generators can be pelton turbines. One or more thermal fluid storage facilities can be used to store heated fluid, and heat may also be stored in a heat retaining material. Additional optional features and combinations of optional assemblies are disclosed. A method of generating electricity with these systems is also described.

Abstract: Process and apparatus for laying fiber bands of filaments by changeably moveable weft or diagonal layers to form fiber arrangements stretched in different laying directions between two transport chains having guide hooks and retainer needles. Fiber bands are spread individually, guided by guide elements for forming a direction change fold, such that strands of each direction change fold are fixed in gaps between guide hooks. Apexes of direction change folds spread out by the guide elements execute racking and are hanged and fixed in a row of densely arranged retainer needles. Upper strands of direction change folds forming between retainer needles and guide elements of weft or diagonal layers are spread horizontally and guided under tension by a stitch spreader moved from outside inwards. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: A device and a method for the adjustment of a temperature of a liquid which is contained in one or more sample vessels are specified, a control unit and a temperature adjustment unit being provided, which acts on the liquid contained in the sample vessels. Furthermore, the control unit is operatively connected to the temperature adjustment unit. The liquid to be analyzed contains absorption elements in order to accelerate the temperature adjustment in the liquid to be analyzed.

Abstract: System for processing samples, in particular samples containing nucleic acids comprising a multichamber arrangement the chambers of which are used to receive liquids and it also concerns a pipetting device for removing liquids from the chambers and/or dispensing liquid into the chambers, wherein the system has a contamination protection which can move relative to the multichamber arrangement and which prevents contamination of an adjacent second chamber with liquid from the first chamber during a pipetting operation in the first chamber, by preventing discharge of fluid droplets from the first chamber into the second chamber by at least partially covering the first chamber.

Abstract: The invention relates to a method and to an apparatus for the production of multi-colored, Jacquard-patterned knitted pile fabrics, the patterning pile yarns being attached to the foundation texture preferably in filling construction and the non-patterning pile-yarns being held predominantly stretched at the foundation texture and, during the knitting process, the group of pile yarns being moveable in closed channels of a guide comb in the traverse and racking direction and the selected patterning pile yarns, guided by means of a pile yarn guide, forming a shed with the non-patterning pile yarns and being supplied by the guide comb in a first course to the reacher-in for accurate racking for the underlapping, the patterning pile yarn, in the second or return course after renewed racking, also being underlapped, tied in and returned in the channel of the guide comb to the dead pile strand and, after the selection of a new patterning pile yarn, the process with the shed formation by the new patterning pile yarn

Abstract: A process for the preparation of 2-oxo-1, 3-dioxolanes comprises reacting an epoxy compound having at least one functional epoxy group in the optional presence of an inert solvent with carbon dioxide at 60.degree.

Abstract: In knitted goods, particularly pile-knit goods, with pile yarn tied into the loops and with weft elements extending at least over two-needle spacings, the pile-forming pile yarns are tied together only in every second course. This may be implemented by tying-in the pile yarns as loop jointly with the meshing yarn while weft yarns and dead piles are preferably tied as weft into the in-between courses. When tying the patterning piles as weft into every second course, dead pile and weft are also ties into these courses, while the in-between course will preferably consist only of the meshing warp yarn.

Abstract: The device for feeding yarn in a textile machine comprises a set of feed driving rollers rotating at a speed exceeding the maximum yarn processing speed in the machine, a first yarn brake downstream of the driving rollers, a first swing support upstream of the rollers, a second yarn brake and a second swing support. Each swing support includes a movable member exerting by its weight a tension against the yarn which causes the latter to engage frictionally the driving rollers. The frictional force exceeds the force of the first yarn brake and advances the yarn about a length which is sufficient to cause the moving member of the first swing support to abut against a fixed stop member so that the tension is released from the yarn and the holding friction changes to a sliding friction which is lower than the braking force of the first brake and thus stops the decoiling of the yarn.
