Abstract: A synthetic fiber fabric for the manufacture of casings for sausages and other meat products consisting essentially of 100% synthetic fibers which are treated by alkalinization or if the synthetic fibers consist of an alkaline resistant material, by an acid solution so that the fabric fibers are modified to render the fabric absorptive to water and additional compounds such as flavor enhancers, smoke flavors, salts or others.

Abstract: A novel lamp socket finding application with a type of increased protection, has a housing part (13) in which a one-piece elastomer sealing sleeve (20) is preferably rotatably held. The sealing sleeve (20) is at its lamp-side end preferably slightly radially compressible, while it is stiffer in the axial direction. As a result, it yields inward when axially pressed by the frustoconical inner side of the housing part (13). The one-piece construction of the sealing sleeve (20) from a single material, on the one hand, ensures a simple manufacture and, on the other hand, prevents a faulty mounting caused by slipped seals or the like.

Abstract: A holder (6), which is suitable in particular for luminaires which do not provide any direct manual access to the capped lighting means, has a slide by means of which the lamp cap and/or the contact pins thereof can be pushed out of the holder or at least released from the holder. In the case of a preferred embodiment, the holder housing (8) is designed in two parts, the housing part (9) being designed as the slide.

Abstract: The present invention is directed to attenuated pestivirus mutants, which have a reduced ability to replicate as exhibited by a small plaque size. The mutations are in the 5? nontranslated region of the viral genome. These mutant viruses are useful as live vaccines in the control of bovine viral diarrhea, border disease and classical swine fever.

Abstract: An angle measuring system for the contactless determination of an angle between a first object and a second object which can be moved with respect to each other, the angle measuring system including a first component having a light source and connected to a first object and a second component having a photodetector and connected to a second object. A grating is connected either to the first component or the second component, the grating having a combined amplitude-phase grating.

Abstract: The present invention relates to a process for the production of a heterologous polypeptide with homogeneous N-terminus in a bacterial host cell, wherein the heterologous polypeptide is autoproteolytically cleaved from an expressed fusion protein which comprises a polypeptide with the autoproteolytic activity of an autoprotease Npro of a pestivirus and the heterologous polypeptide by the Npro autoproteolytic activity.

Abstract: A position measuring device for determining the position of two parts that are movable relatively to one another in the measuring direction, which, in addition, includes the feature of enabling an absolute reference to be established during the measurement. To this end, the position measuring device includes a light source, as well as a beam-splitter element, which splits the beam of rays emitted by the light source into at least one first and one second beam component, which are preferably oriented parallel to one another after leaving the beam-splitter element. Provision is also made for a reference reflector, as well as a measuring reflector, upon which the two beam components strike. A reference marking, as well as a scanning unit are arranged at the measuring reflector and at the reference reflector to produce a reference pulse signal at the position of the stationary reference reflector.

Abstract: The present invention relates to a diagnostic method for the diagnosis of Pestivirus infection in animals, in particular to a method for the diagnosis of animals infected with BVDV. A monoclonal antibody directed to a conserved antigen determinant on the Pestivirus ERNS protein is provided which allows the identification of infected animals with a high sensitivity and specificity.

Abstract: A position measuring system for the determination of the relative positions of two objects which can be moved with respect to each other, as well as a process for operating the same are disclosed, which in case of a relative movement provides at least one pair of phase-shifted analog incremental signals, and which makes possible a definite variation of the signal periods (SP) by at least one signal period variation factor (n) of the analog incremental signals transmitted to an evaluation unit arranged behind it by a signal period variation unit. The signal period variation unit furthermore comprises correction means for eliminating most varied errors in the output signals (SIN′, COS′). Among these are counted errors possibly resulting during the signal period variation, as well as measurement arrangement-specific errors.

Abstract: An absolute measuring interferometer having a measuring interferometer, a tunable laser emitting a laser beam and a control interferometer for adjusting the air wavelength of the laser beam. The control interferometer adjusts the air wavelength of the laser beam to a specific wavelength value at the ends of each measuring cycle. The wavelength of the tunable laser is continually tuned within the specific wavelength interval where the phase change of the interference signal is continually detected during the wavelength modulation process. An absolute measurement is determined by a simple mathematical relationship between the measured wavelength and phase changes.

A switch connected to the second regulating interferometer which turns the second regulating interferometer on when a first output signal is less than a first predetermined maximum signal threshold value or exceeds a first predetermined minimum signal threshold value and if the second regulating interferometer has the next largest regulating section length relative to the length of the regulating section of the first regulating interferometer.

Abstract: An apparatus and method for measuring absolute measurements having two measuring interferometers and a tunable laser emitting a laser beam.
