Abstract: A method and a device for supplying free flowing glass mixtures by transport devices for feeding the glass mixture through a doghouse opening of a glass melting furnace above the glass level, and a pusher driven by a pusher arm for distributing the glass mixture on the glass melt. The transport devices and the pusher arm extend through the doghouse opening and at are least extensively sealed. To feed glass mixture into the furnace and to distribute it over the melt surface in a targeted manner, thereby extensively maintaining the sealing of the interior of the furnace from the surroundings, the glass mixture is applied to the glass melt by two adjacent transport devices and independently controlled with regard to the delivered quantity per unit of time, and is distributed over the glass melt by continuous rotary motions of the pusher at both sides of the pusher arm.

Abstract: A sterilization tunnel for pharmaceutical containers such as vials has an inlet zone, a sterilization zone, and a cooling zone. A conveyor belt for the vials is disposed inside the sterilization tunnel. An emptying device that can be raised and lowered is disposed in the vicinity of the cooling zone. In order to empty the sterilization tunnel, the frame-shaped emptying device is lowered onto the conveyor belt and then pushes an emptying slider, which is being moved through the sterilization tunnel together with the last vials disposed on the conveyor belt, out from the sterilization tunnel. The emptying device permits a particularly simple operation of the sterilization tunnel.

Abstract: A charging machine for charging a glass melting tank furnace includes a reciprocatable charging table above which a hopper is provided for the batch, at the rear side of which at least one movable scraper is provided which seals the slot between the rear wall of the batch hopper and the top surface of the loading table. In order to eliminate the wear on the lower edge of the movable scraper and the surface of the charging table which comes into engagement with the movable scraper, the movable scraper is connected to stroke elements for lifting and lowering, whose stroke is controlled in dependency on the movements of the loading table in such a manner that the movable scraper is lifted during the forward movement of the charging table and is lowered during the return movement of the charging table. In this charging machine, wear occurs only during the table return movement, but not during the table forward movement, so that the wear is cut in half, thus doubling the service life of the machine.
