    摘要： A support pin ―which is to be inserted into a pin insert hole formed in a seed rod provided at an upper end of a glass preform and suspends and supports the glass preform―is formed by coupling a pin main body having a flange section, a first shaft section, a second shaft section, and a male screw section with an auxiliary pin member having a flange section, a shaft section, and a female screw section. The first and second shaft sections of the pin main body and the shaft section of the auxiliarypinmember are providedwith claddings which are formed from synthetic resin and have elasticity. The support pin is formed so that the second shaft section of the pin main body covered with the cladding can be inserted into the pin insert hole formed in the seed rod.

    摘要： Device and method for chemical deposition on an elongated member (2) of vitreous material in which a rotating gripping member (5) causes a first end portion (2a) of the elongated member (2) to rotate (20). The second end portion (2b) of the elongated member (2) is borne by a pair of supporting members (34, 35) which are axially spaced apart (L1) and are capable of permitting angular rotational movement and axial sliding of the second end portion. Each supporting member (34, 35) also applies a radial constraint preventing the second end portion (2b) from moving away from the axis of rotation, thus forcing the second potion (2b) and the elongated member (2) to lie with a longitudinal axis coaxial with the axis of rotation (18). Any curvature of the elongated member (2) is corrected and recovered in this way.

    摘要： The invention relates to a known method for producing a quartz glass body by depositing SiO2 particles on the cylinder jacket surface of a cylindrical mandrel that rotates around the longitudinal axis thereof, whereby an essentially cylindrical porous blank which is provided with an inner bore is produced. The mandrel is subsequently removed and the blank is sintered. The aim of the invention is to modify said known method in such a way that a tube pipe can be welded to the front face of the blank in an unproblematic manner. According to the invention, the mandrel (1) is surrounded by a moulded part (5) in the region of one of the ends (8) of the blank (3) being formed, whereby said part rotates at the same rotational speed as the mandrel (1) and is provided with a core area (6) that faces the blank (3). At least one portion of said core area is detachably embedded into the blank (3) on the front face thereof, whereby said blank is being formed. The moulded part is removed before sintering, whereby a socket of the inner bore pertaining to the blank (3) is produced, said socket being adapted to the core area (6).
