Title: Optical waveguide fibre with low attenuation - where desired profile of refractive index is obtd. by diffusing gas, esp. argon, into vitreous silica fibre
Inventor: SCHNEIDER HARTMUT DIPL CHEM DR
IPC: C03B37/15
Filed: 1978-10-04
Abstract: The fibre has a refractive index(RI) which decreases continuously in the radial direction. The fibre is made from a homogeneous fibre into which a polarisable gas(I) is diffused via high temps. and pressures, the gas being soluble in the fibre and providing the required RI profile. The fibre is pref. vitreous silica, whereas gas(I) is pref. a noble gas; oxygen; N2;H2;HCl; halogen; water; ammonia, or a corresp. deuterium cpd.; CO; or NO. The gas can be diffused into the fibre before, during, or after drawing, and the concn. of the gas near the periphery of the fibre can be reduced by allowing some gas to diffuse out of the fibre, esp. in an atmos. of krypton. An accurate RI profile can be simply obtd. without the danger of impurities contaminating the fibre.

Title: Self-tapping headless lobular insert forming method - forms longitudinally spaced chamfers or bevels on rod by orbital or helicoid movement of latter, using rod side surfaces as guide
Inventor: BOSSE ROBERT W
IPC: B21H3/04
Filed: 1979-07-18
Abstract: The method involves first forming an elongated rod or bar into a specific desired lobular cross-sectional configuration. A number of longitudinally spaced-apart chamfer or bevel portions are then formed by an orbital or helicoid movement of the rod. This movement employs the side surfaces of the rod as a guide, to provide lobular chamfers which comprise smooth continuations of the external lobular configuration. The bevelled rod is then passed through a two die rolling machine in such a manner that the rod describes a helicoid path as it advances, thus forming a thread on its peripheral portions and on adjacent portions of the bevels.

Title: High energy capacitor bank for discharge duty - has each capacitor connected to charging supply via diode
Inventor: RHEINDORF HEINZ DIPL PHYS
IPC: H02H7/16
Filed: 1980-06-20
Abstract: The capacitors (C1....Cn) are connected in parallel between a common bus-bar (4) and a charging bus-bar (1). A diode (DL1...DLn) is placed between the capacitor terminal and the charging bus-bar. The diode prevents any reverse current flow and thus the discharge of energy into a fault, e.g. a short-circuited capacitor or fault in the charger (2). The capacitor output circuit is through a separate bus-bar (3) to which one end of the load (R) is connected, the other end going to the common bar (4). The discharge, or output connection from capacitor to bus-bar may be similarly protected by a diode (DE1....DEn). In this way a destructive discharge into a fault, for whatever reason, is effectively prevented. Typical applications are to pulse generators for exposure lighting, laser or X-ray equipment.
