    摘要： An optical fiber waveguide is disclosed wherein the cladding surrounds a fiber core having a noncircularly symmetric cross section. Equations are presented which dictate the value of the index of refraction that must be provided at each spatial point within the fiber core in order to construct a fiber waveguide having minimum modal dispersion. An especially useful optical fiber waveguide is disclosed with an elliptical fiber core thereby providing a fiber which can be more efficiently coupled to a light emitting source having an elongated source area such as in a heterojunction laser or an edge-emitting light emitting diode.

    摘要： The invention relates to a method for producing glassware, in particular rotationally symmetrical glassware, such as a glass syringe, a glass carpule, a glass vial or a glass ampule, wherein the method comprises the steps of rotating a glass intermediate, in particular a glass tube, with a receptacle rotational speed about a receptacle rotational axis, rotating at least one forming roller with a roller rotational speed about a roller rotational axis, and displacing the at least one forming roller and the glass intermediate for shaping in a forming roller contact, from which the receptacle rotational axis is spaced in a radial direction about an intermediate radius and from which the roller rotational axis is spaced in a radial direction about a roller radius, wherein the ratio of the roller rotational speed to the receptacle rotational speed during the method is controlled as a function of the ratio of intermediate radius to roller radius.

    摘要： Disclosed is a method for the production of a tube having, in sections, a non-circular profile by deforming, comprising: a) providing a tube, which has a circular initial profile; b) conveying the tube in a hot, malleable state through a nip, which is formed by squeezing rollers and has a first nip width, which is larger than or equal to an outer dimension of the initial profile; c) adjusting the squeezing rollers for setting a second nip width, which is smaller than the outer dimension of the initial profile, and deforming the initial profile in said hot, malleable state for obtaining said non-circular cross section; and d) adjusting the squeezing rollers for setting a third nip width, which is larger than or equal to the outer dimension of the initial profile, and severing said tube in a region having a circular cross section; so that respective end portions of said tube have a circular cross section According to the invention, the tubes can be connected reliably with connecting-members or other tubes via the end portions having the circular profile using proven tube connection technologies. At the same time there is at least one central section having a non-circular cross section which is of advantage, for example for applications in photobioreactors.

    摘要： In a device for shaping glass tubes (32), the shaping tools (3, 4), which are designed as shaping rollers, are mounted on a rotary table (2) that encloses the glass tube (32) and that rotates at a speed that is several times higher than the speed of rotation of the glass tube (32). The shaping tools (3,4) are moved in a perpendicular direction to the longitudinal axis (40) of the glass tube (32) in order to shape it. The relatively high speed of rotation of the rotary table (2) allows the advance of the shaping tools per rotation of the rotary table (2) and at the same time the forces that act on the softened part of the glass tube (32) to be kept small.

    摘要： In order to provide a substrate such as an optical preform rod (24) which is suitable for insertion into a tube and which has a transverse cross section that is substantially circular and disposed concentrically about a longitudinal axis of the substrate substantially along its entire length, a force-applying member such as a graphite roller (52) is moved incrementally toward an axis of rotation (35) about which the preform rod is turned rotatably. Movement is discontinued when there is an indication that the force-applying member has been in continuous engagement with the preform rod for at least a predetermined portion of the periphery of the rod. In a preferred embodiment, the engagement of the force-applying member and the preform rod is discontinued after a predetermined time whereafter the force-applying member again is moved toward the axis of rotation. Cycles of engagement and disengagement are continued as relative motion is caused between the force-applying member and the preform rod in a direction along the axis of rotation.
