摘要:
An automated analyzer for performing multiple diagnostic assays simultaneously includes multiple stations, or modules, in which discrete aspects of the assay are performed on fluid samples contained in reaction receptacles. The analyzer includes stations for automatically preparing a specimen sample, incubating the sample at prescribed temperatures for prescribed periods, preforming an analyte isolation procedure, and ascertaining the presence of a target analyte. An automated receptacle transporting system moves the reaction receptacles from one station to the next. The analyzer further includes devices for carrying a plurality of specimen tubes and disposable pipette tips in a machine-accessible manner, a device for agitating containers of target capture reagents comprising suspensions of solid support material and for presenting the containers for machine access thereto, and a device for holding containers of reagents in a temperature controlled environment and presenting the containers for machine access thereto. A method for performing an automated diagnostic assay includes an automated process for isolating and amplifying a target analyte. The process is performed by automatically moving each of a plurality of reaction receptacles containing a solid support material and a fluid sample between stations for incubating the contents of the reaction receptacle and for separating the target analyte bound to the solid support from the fluid sample. An amplification reagent is added to the separated analyte after the analyte separation step and before a final incubation step.
摘要:
The invention relates to a rotatable fairing (1) for a marine riser (2) or other slender marine structure. The fairing (1) is arranged on the riser for reducing watercurrent-induced stresses on said riser (2), said fairing (1) having a tail portion (3) for trailing generally in the downstream direction behind said riser. The fairing (1) is provided with an attenuation unit (8) for counteracting the unstable rotation of said fairing (2) relative to said riser (2), in order to prevent undesired vibrations of said riser (2). The fairing is provided with one or more clamps (10) for attachment to and around a periphery of said riser (2), said clamps (10) arranged with a gear rim (12) for engagement with an actuating cogged wheel (14) of said attenuation unit (8).
摘要:
A method for producing L-threonine using a microorganism is provided. In the method, the threonine dehydratase (tdc) gene existing in the genomic DNA of the microorganism is partially deactivated using a recombination technique. For a microorganism strain with enhanced activity of threonine operon-containing enzymes and the phosphoenolpyruvate carboxylase (ppc) gene, the tdc gene engaged in one of the four threonine metabolic pathways is specifically deactivated, thereby markedly increasing the yield of L-threonine.
摘要:
An apparatus and a method for induction heating of pieces or blanks (10) of electrically conducting and non-magnetic material, wherein a device creates a static magnetic field (3) and a second device is arranged to cause a relative movement (4) between the piece or blank (10) and the static magnetic field (3), so that current is induced (12) in the piece or blank (10) which thereby is being heated up.
摘要:
The invention relates to a device and a method for control of the operation of a thermal projection torch (12), characterized in that the characteristics of the jet (16) and the temperature of the deposit (24) on the piece (22) are measured by means of a camera (54) and a combined pyrometer (70). The correction to be made to the supply parameters of the torch (12) are deduced therefrom and the corrected parameters are transmitted to the unit (30) controlling the torch (12).

The invention relates to a device and method for controlling the operation of a thermal spray torch (12). The inventive device and method are characterised in that an on-board camera (54) and pyrometer (70) are used to measure the properties of the jet (16) and the temperature of the deposit (24) on the part (22) and in that the correction to be made to the supply parameters of the torch (12) is deduced. Furthermore, the invention is characterised in that the corrected parameters are sent to the cabinet (30) that controls the torch (12).
摘要:
An optical network unit (ONU) interconnected by passive optical network (PON) equipment to an optical line terminal (OLT) is identified using secondary modulation of the optical carrier to impress an identifier of the ONU onto the carrier. This resolves a recurring ONU failure mode detection problem caused by failure of a laser driver that causes the ONU to be stuck in an on state.
摘要:
A buckle folding machine (10) includes an operator facing side wall (14) and a side wall (16) remote from an operator, the side walls (14, 16) being arranged at a distance from each other and at least one lower folding pocket (22, 24) being arranged between the side walls (14, 16). The lower folding pocket (24, 26) is guided in a cassette (28) for displacement from an operating position, in which it adjoins folding rolls (26), into a release position, in which it is located at a distance from the folding rolls (26), wherein the lower folding pocket (22, 24) is located outside of a coverage of the operator facing side wall (14) when in the release position, and wherein the cassette (28) is guided such that it can be displaced, perpendicular to the operator facing side wall (14), from an inserted position, in which the lower folding pocket (22, 24) is located within the buckle folding machine (10), into a withdrawn position, in which the lower folding pocket (22, 24) is located outside the buckle folding machine (10).
