    Abstract: The invention relates to a method and apparatus for shaping an elongated glass body 81, which is a glass tube or glass rod and has an initial profile, to an elongated glass body having a different profile. In order to be properly shaped, an elongated glass body 81 passes through, in a hot malleable state, a nip, which is formed by squeezing rollers 1 and which has a nip width which is less than an outer dimension of the initial profile.In order to accomplish an enhanced precision of the shaping process, according to the invention the position of at least one of the squeezing rollers is varied continuously so that a contact area between the respective squeezing roller and the hot glass body is varied cyclic reciprocating movement. Disturbing effects such as local overheating of the squeezing rollers or an accumulation of dirt or glass particles on the surface of the squeezing rollers can thus be effectively prevented.

    Abstract: A method of producing a medium-tight connection between interior and exterior concentrically-arranged glass tubes includes the steps of providing a longitudinally extending electrical conductor strip between the interior and exterior tubes, forming a bulge extending radially outwardly from the interior tube by heating the tube, inserting the interior tube into the exterior tube, and forming a constriction in the exterior tube which extends radially inwardly and connects with the radially outwardly extending bulge to form a closure area, whereby the conductor strip passes through the closure area. An electrochemical sensor for measuring pH values or redox potentials formed according to this method includes an elongated housing which contains an interior chamber defined by the interior tube, a glass membrane cap, and a closure member, and an annular exterior chamber defined by the interior and exterior tubes. The interior chamber contains a buffer solution which covers at least a portion of a working electrode, the working electrode being further connected with an electrical line which passes through the closure member for connection with a connection point located outside of the interior chamber. The exterior chamber contains a reference solution which covers at least a portion of a reference electrode, the reference electrode being connected with an electrical line which extends from the exterior chamber through the medium-tight connection area formed in accordance with the invention to a connection point located outside of the exterior chamber.

    Abstract: A method of preparing a ball-shaped synthetic silica glass optical article. The method includes a step of providing a rod-shaped synthetic silica glass having end faces at both sides thereof and having fewer cords per unit volume viewed in a direction perpendicular to a line connecting the end faces relative to the number of cords per unit volume viewed in a direction along the line connecting the end faces. The synthetic silica glass being optically homogeneous in the direction perpendicular to the line connecting the end faces. The method includes the further step of establishing support portions at the end faces of the synthetic silica glass. The rod-shaped synthetic silica glass is thereupon heated while being rotated around an axis connecting the support portions wherein a molten zone is formed. The molten zone of the rod-shaped synthetic silica glass is thereupon deformed by the application of pressure along the axis connecting the support portions whereupon a high purity ball-shaped optical article, having end faces and a side face positioned between the end faces, is formed. The optical article is characterized by a lesser number of cords per unit volume, viewed in a direction perpendicular to a line connecting the end faces relative to the number of cords per unit volume viewed in a direction along the line connecting the end faces. The rod-shaped synthetic silica glass is furthermore optically homogeneous in a direction perpendicular to the line connecting the end faces. The method is concluded by cutting the ball-shaped optical article at the edge support portions.

    Abstract: Apparatus for forming a groove in a glass tube without contacting the glass tube in the groove region. The apparatus includes a pair of chucks for holding opposite ends of the glass tube. The chucks are coupled to a motor for rotating the glass tube about its longitudinal axis. The apparatus further includes one or more torches for noncontact heating of the groove region of the glass tube sufficiently to soften the glass tube in the groove region. The chucks which hold the glass tube are axially movable for stretching and then compressing the glass tube along its longitudinal axis, when the glass tube has been softened in the groove area. The chucks are rotated during heating, stretching and compressing of the glass tube.

    Abstract: A tubular discharge vessel for a compact low pressure discharge lamp, espally a compact fluorescent lamp, is formed by heating and bending a straight glass tube into a U-shape with a plurality of straight sections and a 180.degree.-bend. Adequate vessel wall thickness is assured at the tubular sections where the bends are formed, by first heating a central section, moving sections lateral to the central section axially toward one another, thereby compressing the heated central section and thickening its walls, and bending or rotating the lateral sections into a parallel orientation. This prevents the bending process from unduly thinning the vessel walls, leading to breakage or rupture under internal gas pressure.
