Patent DE-3622811-A1 (DE)
Title: Smoke generator
Inventor: ZIMMER ROLAND
IPC: A23B4/052
Filed: 1986-07-04
Abstract: The smoke generator presented here serves for generating smoking gases from smoking material (wood shavings, coarse sawdust). Foodstuffs can be smoked with the smoking gases generated. This apparatus can be used particularly well in combination with grilling apparatuses. In the case of infrared grills having addition of smoke, an effect is produced as in traditional grills with wood or charcoal. The technical effect of the apparatus is that an exchange cartridge 2, which is charged before use with smoking material 3, is pushed full into the guide rails 16. The stop 11 is then fixed, the fan 9 is turned on and the smoking material can then be ignited at the perforated plate 5. The smoking material 3 then burns from the perforated plate 5 in the direction of sieve plates 4 and the smoke thus resulting can be further conducted through the rubber moulding 8 and by the fan 9 to the foodstuff to be smoked. If the exchange cartridge 2 is burnt out, it can be replaced effortlessly in a very short time by a second cartridge filled with wood shavings. The smoking operation thus continues almost without interruption. <IMAGE>

Title: Apparatus for the roller flanging of can parts
Inventor: PFAFF ALFRED
IPC: B21D51/26
Filed: 1987-11-20
Abstract: Flanging, can bodies, V-belt drive, flanging spindle, flanging housing, V-belt pulley with internal toothing, intermediate gear set.   The invention is used in flanging machines for can bodies for roller flanging simultaneously on both sides. The solution consists in that, on the processing-space side, the flanging spindle carries a rotatable mounting for the internally toothed V-belt pulley and the pinion, which meshes with the internal toothing via an intermediate gear set supported in the flanging housing, the flanging housing having an opening for bringing the V-belt pulley up to the V belt. The V-belt pulley imparts rotation to the flanging spindle via an intermediate gear set. Depending on the ratio of the internal toothing to the pinion, the flanging spindle rotates up to three times faster than the V-belt pulley. By a known change at the intermediate gear set, the direction of rotation at the flanging spindle relative to the direction of rotation of the V-belt pulley can be changed without changing the speed of rotation of the flanging spindle (Fig. 3). <IMAGE>
