Abstract: The pivoting of a guide roller (20) together with a conveyor belt (19) running around it, as well as a pressing roller (25), from a standby position (A) into a resting position (B) is optimized both for thick dough and for thin dough. The pivoting operation takes place in the case of thick dough after one turn has been wound on the dough reel (18). For thin dough, the pivoting operation takes place after about two turns of the dough are on the reel.

Abstract: A conveyor roller (8) has circular-saw-shaped teeth (28) on its circumference. By means of the conveyor roller set in rotation, shavings are pared off cubes of fat (9) and uniformly fill up the tooth gaps (27). The fat is conveyed along a cylindrical housing part (29) to a nozzle space (36). The nozzle space is bounded by an adjustable end portion (30) of the housing part and an adjustable stripper (32). At the end of the nozzle space, a homogeneous strip of fat is discharged through a nozzle orifice (40). The stripper has a control portion which is actuated by the teeth on the circumference of the conveyor roller. Another stripper portion (37) continually removes the fat in each tooth gap. Fats of very different consistencies can be processed. Optimum plasticization takes place during transformation of the cubes of fat into a strip of fat. The fat is warmed only a very little during the transformation operation. Thin strips of fat having great homogeneity can be produced.

Abstract: An apparatus for humidifying a gas, such as oxygen to be supplied for medicinal purposes, comprises a container for the humidifying liquid (e.g. water) and a mist-producing element which uses the flow of gas to induce a spray of the liquid into the gas space in the container in dependence upon the rate of gas flow.
