Abstract: Apparatus for preparing dough prior to baking houses stacks of dough carriers arranged side-by-side in one or more rows. The stacks are self-supporting. Drive mechanisms step the carriers upward within a stack and laterally between stacks. Downward movement within stacks is by gravity. Vertical movements are one carrier height at a time; lateral movements are one carrier width at a time. The overall movements may follow different modes. The apparatus may include a first dough rising station and a final dough rising station.

Abstract: Show case (1) for keeping and exhibiting objects, the sides (4), the bottom (3) and the cover construction (2) of which encompass the interior of the show case more or less hermetically, wherein filter means (7) comprising preferably dust and/or gas protection filters and being accommodated in an air vent (5) clean air flowing into or being directed into said show case. When air flows in automatically due to changed pressure and temperature conditions inside and outside the show case, the show case is vented preferably through an air vent (6, 9) formed as an outlet valve. When it is impossible to seal the show case sufficiently, it will be ventilated forcibly with the least possible quantity of air by means of a pump or ventilating device connected to the interior of the show case through the filter means, which quantity of air is adapted to the air volumes flowing automatically into the show case when the air pressure increases suddenly or the temperature varies.

Abstract: To provide intimate contact between a sinter body holding a drawing die in ontact with a die support carrier, so that the setting will fit into a cup-shaped die holder, the carrier is a disk element having a base plate from which a stub leg, preferably in frusto-conical form, extends, defining a reentrant surface, the wider portion of which is spaced from the base plate, with a seating surface extending therefrom for the die, and the sinter body surrounding the die, extending into the reentrant surface defined by the conical projection of the stub leg from the base plate, and extending beyond the die, and fitting in the die holder, the setting being inserted in the die holder with the sinter body against the bottom of the cup-shaped die holder to accept compressive forces upon drawing of wire in the direction from the base plate through the diamond and then through the sinter holder, that is, reversed with respect to the customary direction, so that the sinter body will be placed under compression and in inti
