  • Optical position-measuring device
    Patent number: 6497049
    Abstract: An optical position-measuring device is described, that includes a scale and a scanning unit movable relative thereto, a light source, one or more scanning graduations, at least one opto-electronic detector element and a mirror lens arranged downstream of the light source. The mirror lens includes a plane reflector surface and two partial surface areas having different radii of curvature. The beams entering through a first partial surface area impinge on the reflector surface and are reflected from the reflector surface in the direction of the second partial surface area. A collimated beam exists subsequent to exiting the second partial surface area.

  • Detection and quantification of micro-organisms using amplification and restriction enzyme analysis
    Patent number: 6495325
    Abstract: In livestock, a number of pathological conditions and/or syndromes exist which may not be attributable to infection by a single organism. In many instances, these pathological conditions and/or syndromes have an effect on the equilibrium that ordinarily exists within the various bacteria comprising the normal bacterial flora. A number of these pathological conditions and/or syndromes have been clinically referred to as dysbacteriosis and bacterial overgrowth. The present invention provides methods for evaluation of the “general health” of livestock by analyzing the composition of microbiological flora. In one aspect, a method of the invention comprises providing a sample of microbiological flora, selectively amplifying nucleic acid in the flora sample, subjecting the amplificate to restriction digestion, and then analyzing the resulting pattern of restriction fragments.

  • Thienylazolylalkoxyethanamines, their preparation and their application as medicaments
    Publication number: 20020188017
    Abstract: The thienylazolylalkoxyethanamines (I) where R1 is a hydrogen atom, a halogen atom or a lower alkyl radical; R2, R3 and R4 represent, independently, a hydrogen atom or a lower alkyl radical; and Az represents a five-member nitrogenated hetercyclic aromatic group, N-methyl-substituted, that contains from one to three nitrogen atoms. They have analgesic activity in mammals, including humans. The compounds (I) can be obtained, for example, by reaction of a derivative of hydroxy-thienylazol (IV) with a derivative of a suitable N-(ethyl)amine. The compounds (IV) are useful intermediates in the synthesis of the compounds (I). The compounds (I) have an application in human and/or veterinary medicine.

  • Method of non-linear route display
    Patent number: 6493602
    Abstract: A method of non-linear display of routes of a machine-tool or another mechanism and including determining a set path based on stored commands and determining an actual path based on actual displacements during operation of the machine-tool or another mechanism resulting from execution of the stored commands, graphically displaying the set path and components of the actual path, which extend parallel to the set path, at a first scale, graphically displaying components of the actual path, which extend perpendicular to the set path, at a second scale, and graphically displaying at a selected points of the set path, the set path and the components of the actual path, which extend parallel to the set path, at a third scale and the components of the actual path, which extend perpendicular to the set path, at a fourth scale.

  • Method and circuit for adjusting a switching threshold of a touch probe
    Patent number: 6487785
    Abstract: A circuit for adjusting a switching threshold of a touch probe, which has a touch element that can be deflected out of a position of repose and which upon a deflection of the touch element out of its position of repose causes a defined change in a measurable system parameter and outputs a switching signal when the value of the system parameter exceeds the switching threshold. The circuit includes a device for measuring the measurable system parameter, an electrical circuit for ascertaining a reference value from which the switching threshold is determinable and an incremental corrector that changes the value of the measurable reference value to the value of the measurable system parameter at the position of repose of the touch element, in which the switching threshold is determinable from the reference value.

  • Arrangement for rotatably supporting an element rotatable about an axis
    Patent number: 6487929
    Abstract: A braking arrangement for rotatably supporting an element rotatable about an axis such as a control wheel, rotary control knob or the like, for example for a vehicle fresh air nozzle, has a plug-shaped casing with an end portion and a peripherally extending flange extending away from the end portion and having a circular external peripheral surface. The external surface of the flange forms a rotary mounting surface for the rotatable element. The flange encloses a central guide space for two braking members which have braking portions facing diametrally away from each other. The braking portions extend through transverse holes in the flange. The two braking members are urged away from each other by a spring disposed therebetween.

  • Optical detector for measuring relative displacement of an object on which a grated scale is formed
    Patent number: 6486467
    Abstract: Electronic components of an optoelectronic sensor for a measuring system are arranged on the side of a semiconductor substrate that is facing away from a scale. The semiconductor substrate between electronic components and the scale is removed at those locations where the components emit or detect an electromagnetic beam. In this way, it is possible to arrange all of the electrical connections of the components and further electronic assemblies of the measuring system on a first side of the semiconductor substrate, and all optical components of the measuring system on a second side of the semiconductor substrate.

  • Method for providing fail-safe secure data transmission between a numerical control system and a spatially separate unit
    Patent number: 6487695
    Abstract: A fail-safe system to connect a mobile input unit with a machine control unit, implementing a redundant preprocessing of the user inputs in the mobile input unit. The signals from the input means are routed to two processors of the input unit, and both processors encode the user inputs before transmitting the signals to the control unit. In the control unit, the received and encoded user inputs are decoded by two processors and subsequently compared to one another for concordance. When concordance is given, the received data is further processed in the control. If there is no concordance, an error routine is executed, shutting down the machine tool.
