Abstract: A method of green joining ceramic components is disclosed, particularly for use in forming a discharge body for a ceramic metal halide lamp. The process includes providing a first green ceramic component having a male joining surface, and providing a second green ceramic component having a female joining surface dimensioned to matingly receive the first component. The first and second green ceramic components are assembled along the joining surfaces, the assembled components are uniformly heated to join the first and second components. The joined components are next cooled in a cooling bath that uniformly cools the joined components. Thereafter, the joined green part may be inserted in the furnace for debindering and sintering.

Abstract: A rotary switch and a flashlight incorporating same are described. A cylindrical housing encloses a button-type battery cell and provides a grounded inwardly protruding, inwardly biased resilient wiper. A rotor, movably approximated to the housing, has a generally cylindrical hub defining one or more contact areas on its side surface for selectively electrically connecting a bulb or other device to the battery cell by rotating the rotor relative to the housing. The rotor further defines a retaining tooth which engages a retaining groove on the outer surface of the housing to keep the rotor on the housing. Rotational position is stabilized by cooperation between a the wiper and a contact surface or between the rotor shell and a position key formed on the housing. The rotor hub is configured to house a circuit module for interposing desired electrical functions between the bulb and the battery cell.
