Abstract: An apparatus for producing a glass-coated wire, the apparatus comprising at least one heating device adapted to, independently, heat a core material to a melting temperature thereof and heat a glass material to a drawing temperature thereof.

Abstract: A glass-to-metal bushing for ignitors of airbags or belt tensioning pulleys. A metal pin is arranged in a slot in the base plate in the fixing material, the base plate being formed by one element whereby the base geometry describing the slot is produced by at least one separation process. Structure is provided between the front and rear of the base plate for preventing relative motion of the fixing material in the direction of the base plate rear portion across from the inner circumference of the slot.

Abstract: The device and process allow for continuous processing of metal wire sheathed in glass (10) of considerable length. Normally a feed pipe (15) containing all the necessary metal, itself placed into a glass tube (20), so as to continuously supply a bead (14) to the lower part of the glass tube (20). Heat from a first inductor (23) around the glass tube (20) and a second inductor (24) under the glass tube (20) allow to maintain a bead (14) at a stable temperature and in a continuous manner and to obtain the continuous drawing process of a metal wire sheathed in glass (10).

Abstract: The method includes the steps include: providing first and second sheets of translucent glass having first and second principle sides coating at least a portion of at least on of the first principle sides of the first and second sheets with a layer of ceramic paint; placing the first and second sheets of coated translucent glass together such that the first principle surfaces are in contact with each other forming a sandwich; applying a layer of material on at least a portion of an external surface of at least one of said first and second glass sheets that will cause differential heating of the layer of ceramic paint applied to at least a portion of at least on of said first principle sides of said first and second sheets when the sandwich is heated to temperatures which will fuse the first and second sheets together; and heating the sandwich to a sufficient temperature for a sufficient time such that the first and second coated sheets of glass are fused together.
