Abstract: This invention relates to an isolated nucleic acid fragment encoding a sulfate assimilation protein. The invention also relates to the construction of a chimeric gene encoding all or a portion of the sulfate assimilation protein, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the sulfate assimilation protein in a transformed host cell.
Abstract: A ratchet mechanism for the headband of a protective helmet or other headgear is designed to function in high-temperature environments, while still allowing for ready adjustment of the size and fit of the headband. In this regard, the ratchet mechanism includes a rotational element that has a pinion adapted to mate with and engage the respective rack gears of the overlapping rear end portions of the headband, such that rotation of the rotational element causes lateral movement of the overlapping rear end portions with respect to one another. A spring assembly associated with the rotational element engages a ring gear defined by an insert received and retained in the housing so as to resist rotation of the rotational element relative to said housing sections. Since the spring assembly and insert are preferably manufactured from metal, they do not suffer from warping problems, and therefore, the ratchet mechanism continues to function properly even in high-temperature environments.
Abstract: A process for producing low molecular weight, granular polytetrafluoroethylene or modified polytetrafluoroethylene by suspension polymerization of pressurized tetrafluoroethylene in an agitated reaction vessel. The polymerization is conducted in aqueous medium in the presence of a free radical initiator, and a telogen. The reaction vessel is agitated during polymerization sufficiently to coagulate the polytetrafluoroethylene or modified polytetrafluoroethylene. Low molecular weight granular polytetrafluoroethylene or modified polytetrafluoroethylene having a melt viscosity of less than about 1×106 Pa·S powder is isolated directly from the reaction vessel.

Abstract: In a method for cutting structural components to be joined by laser radiation that is guided by a computer-controlled manipulation system provided with a nominal path for each structural component corresponding to a joining line that is curved as a result of at least one of the structural components being three-dimensionally shaped, the structural component surfaces of the structural components including the joining line are determined measuring technologically. Based on measuring results, the nominal path corresponding to a penetration line of the structural components to be joined is calculated. A marking is formed on a first one of the structural component surfaces. When performing the cut on the structural component surface provided with the marking, the resulting cutting gap and the marking are determining measuring technologically. When a deviation of the cutting gap from the nominal path is detected, the manipulation system is controlled to correct the deviation.

Abstract: Tomographic projection data is segmented spatially by forming segmentation masks over the full outlines of objects appearing in isolation within selected data frame images. Further processing locates the object outlines in other data frames. Predictable effects of attenuation are used to attribute appropriate amounts of intensity to the segmented object space. Separate image reconstructions can be made of the segmented object data and the remaining projection data to independently optimize the reconstructions. Composite images can be made of the separate reconstructions.
Abstract: This interface is an apparatus for controlling a power supply delivering power to a DC powered tool. The interface is connected between the DC power supply and the DC tool wherein the interface is configured to read signals from the tool and control the power supplied by allowing the power supply to run, brake, reverse or jog the tool. A microprocessor is connected to the interface programmed to provide a specific power in response to the signals from the tool read by the interface. The interface includes a number of field effect transistors. They are PFET1, PFET2, NFET1, and NFET2.
Abstract: An insulating label stock including a thermal insulating layer, which may be fiberfill batt, is provided. The batt is laminated to at least one layer of film, paper or fabric. Also provided is a method of making the insulating label stock. The insulating label stock may be wrapped around a container, such as a can, bottle or pouch. Further, the insulating label stock may be coated with a coating material so that it is printable, thus imparting both insulating properties and print capability to a container.

Abstract: A fiber textile semi-finished material is fed directly and reformed onto a carrier and reforming tool, where it is fixed with a binder. The carrier has a contour matching the negative or positive shape of the final required geometry of a preform that is to be fabricated. The reformed semi-finished article fixed with the binder is removed from the carrier to provide the preform. Several preforms of different cross-sectional shapes are joined together, compacted to form a dense component having nearly the required finished contour, impregnated with a matrix system including a curable adhesive resin, and then cured under an elevated temperature and/or pressure. The result is a finished fiber reinforced composite structural element such as an aircraft window frame. This method is carried out on an apparatus including the rotating carrier and reforming tool, which may have a cylindrical and/or annular surface for receiving and reforming the material.

Abstract: The invention relates to a method and a device for transmitting information symbols using a plurality of carriers, wherein a first transmission symbol is produced (52, 54) on the basis of an information symbol. A second transmission symbol is also produced (52, 54) on the basis of the same information symbol, wherein the second transmission symbol differs from the first transmission symbol. The first and second transmission symbols are modulated (56) on a carrier and transmitted (62) at different intervals. The invention further relates to a method and a device for receiving information symbols represented by the first and second information symbols, wherein both transmission symbols received are used in order to extract the information symbol contained in both transmission symbols.
