  • Patent number: 6543093
    Abstract: A fiber processing machine includes an arrangement for forwarding a sliver through a space in an advancing direction; an arrangement for continuously displacing the sliver in the space transversely to the advancing direction while the sliver is forwarded in the advancing direction; and an apparatus for detecting a presence, absence, motion or standstill of a sliver. The apparatus includes a transmitter emitting a sensor beam passing through the space transversely to advancing direction for being intermittently interrupted by the sliver during displacement thereof transversely to the advancing direction; and a receiver positioned in a path of the sensor beam for receiving a light or a dark signal dependent whether or not the sensor beam is interrupted by the sliver during displacement thereof transversely to the advancing direction.

  • Patent number: 6483982
    Abstract: A reflecting-mirror-type variable optical attenuator based on a new principle is provided. A reflecting-mirror-type variable optical attenuator according to the present invention is formed of a collimator lens with optical fibers in which two optical fibers are attached to a rod lens in respective positions off-centered from the optical axis of the rod lens and a linearly movable reflecting mirror. A phenomenon that the optical axis of a light beam emitted from one optical fiber deviates from the optical axis of the collimator lens by the angle according to the off-centered distance on the surface of the rod lens is utilized. That is, by changing the distance between the surface of the reflecting mirror arranged to be linearly movable in the optical axial direction back and forth and the surface of the rod lens, input light from one optical fiber is attenuated to be output to the other optical fiber.

  • Patent number: 6467175
    Abstract: The invention relates to a spoon for receiving soft or liquid food. Said spoon has a handle with an attached mouthpiece constructed of soft and flexible material. The aim of the invention is to significantly simplify the manner in which food is received by small children and people with facial paralysis. The spoon has a practical shape in that the mouthpiece is trough-shaped and concave and has a level defining upper edge, whereby the thickness of the mouthpiece in the front and on the lateral side is proportional so that its concave shape can be inverted by the pressure of the tongue (Z) during swallowing and the mouthpiece can adapt to the arched shape of the hard palate (G) in a sagital and transversal direction.

  • Patent number: 6457209
    Abstract: A method of directly determining setting values for an application point of regulation in a draw unit for drafting sliver includes the following steps: Obtaining at least three measured values of a quality-characterizing magnitude, such as the CV value, of the drafted sliver; utilizing the measured values for formulating a function having a minimum constituting an optimal application point of regulation for controlling the draw unit; determining the optimal application point of regulation in a pre-operational run of the draw unit; and numerically computing a function between the quality-characterizing magnitudes and application points of regulation from the measured values.

  • Patent number: 6454205
    Abstract: A fin-stabilized projectile includes a projectile body having a rear portion defining a rearwardly open cavity and a stabilizing assembly which has an axially slidable fin support in the cavity. The fin support has a retracted position in which the fin support is withdrawn into the cavity and an outwardly shifted position in which the fin support projects from the projectile body. A plurality of fins are pivotally held in the fin support. Each fin has a folded state in which it is withdrawn in the fin support when the latter is in the retracted position and a deployed state in which it is unfolded and extends substantially externally of the fin support when the latter is in its outwardly shifted position. When the projectile has left the weapon barrel, the fin support is axially shifted and the fins move into the deployed state.

  • Patent number: 6452157
    Abstract: An apparatus for detecting foreign bodies in fiber material includes at least two light sources. At least one of the light sources has at least three light emitting elements. Each light emitting element radiates a light of different color. An arrangement directs the light emitted by the light sources to the fiber material for illuminating the fiber material, and a sensor detects the illuminating light after illumination of the fiber material for emitting an electric signal upon a sudden color change of the fiber material. An arrangement causes the light sources to alternatingly illuminate the fiber material with different colors, and further, an arrangement selects the color emitted by the light sources as a function of the color of the fiber material.
