摘要:
For the genus-specific or/and species-specific detection of bacteria in a sample liquid, bacterial RNA is hybridized with a primer which is complementary to a genus-specific or species-specific region of the RNA of particular bacteria or to a highly conserved region of the RNA of bacteria in general, but which is not complementary at its 3′ end to the RNA of bacteria of another genus or species, the primer is elongated in the presence of a suitable polymerase and the four deoxyribonucleotides, if desired, with a concurrent or subsequent labelling of the elongation product and an elongation product formed is hybridized with a genus-specific or species-specific oligonucleotide after denaturation and the hybridization is detected by means of the oligonucleotide label.
摘要:
A drilling tool includes a hydraulically driven device (21) for advancing a drilling head (2) in a bore (5), and a flow limiter (30) arranged in a hydraulic conduit (25) of the advancing device (21) for adjusting an advancing speed of the drilling head (2) in the bore (5), with the flow limiter (30) having a pressure-actuated adjusting member (38) for adjusting flow of a hydraulic fluid in the hydraulic conduit means (25) in accordance with a flow volume of a rinsing fluid (7) for rinsing the bore.

A self-drilling connection anchor (10) includes an anchor tube (11), a drilling head (13) provided at the first end (12) of the anchor tube (11), an inner tube (15) arranged in the anchor tube (11) and having an interior space (16) for receiving an ejectable mass (30), a first axial, with respect to the longitudinal axis (L) defined by the anchor tube, opening (18) provided in a region of the second free end (14) that communicates with the interior space (16) of the inner tube (15), at least one outlet opening (20) provided in a region of the drilling head (13), and at least one second radial, with respect to the longitudinal axis (L), opening (19) provided in the region of the free second end (14) and communicating with the at least one outlet opening (20) via an intermediate space (17) formed between the anchor tube (11) and the inner tube (15).
摘要:
The invention relates to an operating method for a regeneration valve of a fuel vapor retention system, particularly of a tank vent valve for regenerating an activated carbon filter during which the regeneration valve is controlled by a control signal, whereby the control signal corresponds to a designated valve position of the regeneration valve. The invention provides that the correlation between the control signal and the resulting valve position of the regeneration valve is determined during a calibration process.
摘要:
A fastening element, which is used in particular in mines and/or tunnel construction, includes an anchoring tube (2), a squeezable-out, one-or multicomponent chemical mass contained in a foil bag (5;25) arranged in the anchoring tube (2;2) between spaced from each other, first stop (7,27) and second stop (9), and at least one pressure application element (14) arranged between the first stop (7,27) and/or the second stop (9) and a respective axial end region (11,12;31) of the foil bag (5;25) for applying pressure to the foil bag (5;25) in a shelf condition of the fastening element (1;21)
摘要:
An anchor rod to be received in a bore filled with mortar mass including a connection region (2, 22, 32) having a plurality of axially arranged one after another, conical enlargements (4, 24, 34) a diameter of which increases in a setting direction and which are provided with circumferential sections (5, 25, 35) radially spaced from a longitudinal axis of the anchor rod (1, 21, 31) by a greatest distance, having a radius (r) smaller by from about 0.1 mm to about 1.5 mm then a half of a nominal diameter of the anchoring region receiving bore, and extending, respectively, in a circumferential direction over an angle of up to 300°.
摘要:
A setting tool for anchor rods of attachment anchors, which have a rear end section (P) having a polygonal cross-section, the setting tool including a housing (2) provided with an insertion end receivable in a chuck of a percussion rotary drill and a rod receptacle (5) provided at an end of the housing opposite, in an axial direction (A), to the insertion end (5), the rod receptacle (5) having an axially extending inner surface (6) provided with at least two ribs (7) projecting therefrom and extending in the axial direction (A), with the ribs (7) defining an inscribed cylinder (Z) having a diameter (x) larger by from about 0.05 mm to about 0.5 mm than a diameter (y) of a circle (K) inscribed in a polygonal cross-section of the rear and section (P) of the anchor rod.
摘要:
Poultry carcasses, especially for rotisserie roasting, are differentially injected with the same or different marinates, especially to provide a greater proportion of the marinating solution in the breast portions than in the leg and other portions. The differential injection is accomplished by providing a greater flow cross section of the needles ill the breast portion than in the leg and other portion for greater numbers of needles at the breast portion than at the leg an other portion, and/or by pumping the solutions at a greater rate to the breast portions than to the leg and other portions.
