  • Publication number: 20040124214
    Abstract: In a cartridge for a fluid, as well as a system for handling a fluid using such a cartridge, the cartridge has a tank shaped as a cylinder with an opening to admit and discharge the fluid, as well as a piston that can be moved forward and/or back in the tank in order to pump the fluid in or out through the opening. The piston has a connection element that can be connected with an actuator in order to move the piston forward and/or back. The connection element and the actuator are adapted to one another such that the connection is automatically closed in a first longitudinal section of the tank, given movement of the piston in the longitudinal direction and is automatically released again given movement in the opposite direction, and the connection remains closed in a second longitudinal section of the tank given movement of the piston into this second longitudinal section.

  • Patent number: 6702223
    Abstract: A winding head of a cheese-producing textile machine, having a device for the accurate determination of the length of yarn traveling through a measuring head (7), and having an evaluating device for accumulating the yarn lengths that have passed. The winding head has a device for determining yarn length portions which are removed in the course of a yarn connecting process. The evaluation device is adapted to subtract the removed yarn lengths from the total length of the yarn (2) which has passed through the measuring head.

  • Publication number: 20040035389
    Abstract: With a method for controlling the fuel supply to an internal combustion engine, in particular to a two-stroke motor, a parameter (K) of the machine, which is influenced by the fuel supply in a delayed manner, is tuned to a predetermined desired value (SW) by switching on and cutting off the fuel supply. The hysteresis is largely compensated in that an upper and/or lower threshhold value (OS,US) is allocated to the desired value (SW) of the parameter (K), that the parameter (K) is continuously measured, and that the fuel supply is cut off when the measured parameter (K) crosses the lower and/or upper threshhold value from below to above, and that the fuel supply is switched on when the measured parameter (K) crosses the upper and/or lower threshhold value (OS,US) from above to below.

  • Patent number: 6582180
    Abstract: An object-sorting system has a conveyor having a horizontally extending stretch, a plurality of pushers fixed on and spaced along the conveyor and extending upward from the stretch thereof, and an upright chute adapted to hold a stack of objects and having a downwardly open outlet spaced above an upstream end of the conveyor stretch. An elongated support surface extends horizontally above the stretch and has an upstream end below the outlet port. A drive advances the stretch and thereby displaces the pushers downstream past the outlet so that the pushers engage at least a lowermost object of the stack in the chute and move the engaged object(s) downstream along the support surface. The support surface can pivot about an axis at the support-surface downstream end and thereby change a vertical spacing between the support surface upstream end and the outlet port.

  • Patent number: 6580813
    Abstract: A method and apparatus of detecting residual yarn on spinning cop tubes, wherein a spinning cop tube is exposed to a suitable light source; the light reflected by the spinning cop tube is detected by a suitable means, e.g., via a camera or other picture-taking device, and two-dimensional picture signals of the spinning cop tube are generated thereby on the basis of the reflected light detected in order to generate a picture matrix comprising picture data in digital form; and the picture signals thusly generated are evaluated by means of performing an edge filtering of the digital picture data in order to segment image edges corresponding to brightness transitions in the picture matrix, from which the presence of residual yarn on the spinning cop tube can be assessed based on the edge filtering.

  • Patent number: 6564470
    Abstract: An appliance for thermally processing granular material, especially for roasting food items such as coffee beans. The granular material lies on a perforated base through which gas flows upwardly to create a fluidized bed. The exhaust gas is fed to a cyclone separator for separation of entrained solid particles. Preferably, the base is located in an inner chamber which is at least partially enclosed in an outer chamber forming the cyclone separator. The exhaust gas is fed into a top opening of the outer chamber thereby providing a rotary gas flow. Alternatively, the base is located in an outer chamber in which at least the area above the base is designed as the cyclone separator. The outer chamber at least partially encloses an inner chamber through which gas is fed to create a rotary gas flow. In both cases, an extremely compact roaster design is realized.

  • Patent number: 5994860
    Abstract: In a series-wound motor with electric brake, which comprises an armature provided with an armature winding and at least two exciter coils mounted on pole shoes as well as switchgear which, in the operative phase of the motor, serially connect the exciter coils with the armature winding and connect the serial connection to terminal clamps for the operating voltage and which, in the braking phase, interrupt the connection to the terminal clamps and short-circuit the armature winding by the parallel connection of a winding, an independent optimization of the braking behavior is made possible in that at least one of the exciter coils is subdivided into two part windings and in that, when braking, one of the part windings has its polarity changed and is short-circuited with the armature winding.
