Abstract: A synchronous guide of a drawer element mounted on a body of a piece of furniture or household appliance via pullout guides. The synchronous guide includes two stationary toothed racks located opposite each other, each toothed rack associated with a side member of the body. Further included are two gear wheels, each of which is mounted on one of the pullout guides, the gear wheels being connected via a coupling rod. The gear wheels are mounted in a stationary manner on running rails of the pullout guides. A piece of furniture or household appliance includes a drawer element mounted on a body of the piece of furniture or household appliance via pullout guide and includes a synchronous guide as described above.

Abstract: A holding device includes two shaped parts which can be fixed on mutually opposite walls of a piece of furniture. The shaped parts have several slide-in grooves which extend toward one another at various angular positions and into which a preferably plate-shaped component can be slid to a stop.

Abstract: In the manufacturing of high melting point glasses with volatile components, in particular of glasses from the group of boron glasses and borosilicate glasses, a furnace is provided that has a superstructure, fossil fuel burners, and a melting tank. In front of a conditioning zone and a throat leading to an extraction zone, a step-shaped raised area in the bottom is provided which is formed continuously over the complete width of the melting tank. In order to suppress segregation or, respectively, phase separation, to protect the furnace construction materials and to enable problem-free operation, a temperature of at least 1600.degree. C.
