IPC: A47L11/162
Filed: 1984-04-14
Abstract: For the purpose of achieving the optimum rotational speed of the respective working tool (4) of floor-cleaning machines required in each case for different floors or floor coverings, provision is made for the motor speed to be transmitted to the drive shaft (5) of the rotary brush (4) via a preferably mechanical variable speed gear (6, 12, 13, 14, 15) which is infinitely variable during the operating state. In this case, the appropriate gear mechanism consists in its simplest form of a pair of adjusting discs (12, 13), seated on the motor shaft (16), having a V-belt (14) which leads to the drive disc (6) of the working tool (4), and having an associated adjusting drive (19 to 22) which causes a displacement of the motor (13) and slide (17) on the guide rods (18) of the basic frame (1) in the sense of changing the axial spacing between the two pulleys (6 and 12, 13).

Patent DE-3438213-A1 (DE)
Inventor: SCHMIDT HEINRICH
IPC: B65B29/02
Filed: 1984-10-18
Abstract: A process for manufacturing articles of filter paper in which the wet strength of the regions of weak points resulting from mechanical working is increased by the application of a wet strengthener of cross-linked cationic polyalkylenimines. For this purpose, the wet strengthener is applied only to the regions of the weak points after the filter paper has been manufactured. Seams or edge reinforcements are formed by relief printing before the application of the wet strengthener and a heat treatment takes place after application of the thermoplastic wet strengthener to cause the wet strengthener to harden. The application of the wet strengthener is effected in measured doses so that the legally prescribed maximum amounts to be added are not exceeded.
