  • Patent number: 5871033
    Abstract: A suction for the combustion air of a heater, in particular a motor vehicle heater, has a variable cross-section of flow. The object of the invention is to improve the operation of the device that modifies the cross-section of flow and to allow it to be more rationally produced. In addition, it should allow the suction air to be filtered in association with said means without extending the axial length of the heater. For that purpose, the suction pipe is designed as an axially closed tube with radial openings whose cross-sections may be changed by a coaxial, rotary ring set on the outside of the pipe and provided with radial openings. A hood may be axially drawn over the ring on the housing of the heater. Suction air may be filtered in said hood, either by centrifugaton in spiral channels arranged in the hood or by using a ring-shaped filter through which the suction air flows in the radial direction.

  • Patent number: 5868310
    Abstract: A collar flexibly movable between a first shape defining an opening for receiving one end of a cup and a second shape where the collar is substantially flat. A handle is flexibly connected to the collar. Tension members attach to the handle and collar on opposite sides of the handle to provide two opposing forces which prevent the handle from moving with respect to the collar.

  • Patent number: 5865667
    Abstract: The part (1) to be machined, which exhibits an axis of revolution (aa') is secured in a rotatable spindle (11) forming part of a headstock (10) movable in translation on the framework of the grinding machine according to a longitudinal axis (X) parallel to the axis of revolution (aa'). A support (16) fixed to the framework and in the immediate proximity of which is arranged a grindstone (18), serves as lateral support to a portion of the part (1) to be machined. Grinding of the part (1) by the grindstone (18) over an arbitrary length capable of exceeding 1000 times its diameter, is effected by displacing the headstock (10) by such length in the sense of the longitudinal axis (X).

  • Patent number: 5866794
    Abstract: A device for calibrating a gas meter, in which gas to be analyzed is introduced into a measuring chamber by a delivery device via a delivery line. A storage tank is provided containing a calibrating substance, which tank is connected to the measuring chamber via a feed line. The storage tank is designed as a tank through which the gas to be analyzed can flow and has a gas inlet. A flow divider is provided in the course of the delivery line. A partial flow of the gas to be analyzed is sent by the flow divider to the gas inlet via a section of the feed line. The gas meter is an electrochemical measuring cell determining a measured concentration value of the calibrating substance in the gas to be analyzed in the measuring chamber. An infrared meter is provided, which evaluates the gas to be analyzed in the measuring chamber and generates a reference measured concentration value for the measured concentration value determined with the electrochemical measuring cell.

  • Patent number: 5865402
    Abstract: A triaxially stabilized earth oriented satellite is provided with an attitude control system. The attitude control system contains a controller, final control elements for generating control torques around each of three axes of a system of coordinates (principle axes x, y, z) fixed relative to the satellite. Additionally, the attitude control system comprises, as measuring transducers, exclusively a direction vector measurement device, like a magnetometer or star sensor, a sun sensor array and an earth sensor. The process of the invention makes use of the apparatus as noted above and includes the steps of:A. determining an estimate for the rotating velocity of the satellite from a direction vector measurement;B. searching for the sun, depending on the size of the field of view of the sensor, by one or two search rotations at right angles to the optical axis;C. adjusting the direction of the sun relative to the optical axis; andD. adjusting the direction vector measurement to a reference direction S.sub.

  • Patent number: 5859786
    Abstract: A process and system for the computer-aided geometry modeling which makes possible a declarative, sequence-independent description of geometric shapes and geometric features and leads to an integrated modeling, which unites in itself geometric relationships and connects them with non-geometric information. To achieve this, the geometry-related information is represented in the form of a representation element, to which a density (.rho.) is assigned in the form of a real number. The linking of individual representation elements is performed by a single commutative and associative linking operation. A volume level, a topology level, and a generic area and edge level located between these levels are provided as the description levels for the actually relevant information. A feature level, at which features are defined and at which a knowledge-based system can be used, is located above these description levels.
