Patent DE-4032387-A1 (DE)
IPC: E03D9/03
Filed: 1990-10-12
Abstract: A device is disclosed that may be used in the water tank or in the bowl of a water closet in order to add thereto in the last flushing water or after flushing, a dose of a liquid active substance. The product container (1) is hung so that it can turn anti-clockwise over 90 DEG , dispensing some of the product in this position into the measuring cap, from which it drips once the product container tips back. Tipping is ensured by the weight of the water that accumulates in a flushing water collector (20) arranged in the water tank and that tips the product container (1) to the left when the water level sinks below the measuring cap during flushing; a dose is dispensed in this position, flushing water escapes through the opening (22), the flushing water collector (20) becomes lighter again, so that the product container tilts back. In the toilet bowl, the collecting container (20) collects water during flushing, becoming heavier and causing the tipping. Flushing water may also be collected in a larger collecting container (8a) in which the product container (1) is rotatively hung.

Patent DE-4116081-A1 (DE)
Inventor: STEFFL MANFRED DIPL ING
IPC: B65H23/00
Filed: 1991-05-16
Abstract: A process and device are disclosed for determining in particular the relative winding thickness of a foil strip (1) wound-up on a winding reel (3) and a regulation process allows a preselectable, in particular relative winding thinckness to be obtained. Until now, it was not possible to determine the relative, specific winding thickness, in particular during the process of winding a foil on a winding reel. According to the invention, this is possible by measuring the foil thickness during winding of the foil strip, by measuring the total length of the foil strip to be wound-up, by measuring the wound-up bale diameter at all points in time and by calculating the winding thickness from the formula  rho = FD x FL / BRfl, in wich FD stands for the foil thickness, FL for the total length of the foil and BRf1 for the frontal, annular surface of the woundup bale (9) on the winding reel. The relative winding density can be used as the starting point for a regulation process of the winding traction forces that draw on the winding reel, as well as of the compressing forces in the case of a contact reel. The corresponding device has a simple design.

Title: Manufacturing method for profiled disc for oscillation damper housing - forms circumferential gap in circular body, to form projecting ring sections without re-chucking
Inventor: MEIER JOSEF
IPC: B21H1/04
Filed: 1991-06-07
Abstract: The method is for manufacture of a profiled disc, e.g. for use as a housing for an oscillation damper. It has a disc-shaped circular body, with two vertically projecting ring sections. The sections are at a relative distance, and are concentric to the main body. A circumferential gap is formed in the edge of the disc. The gap has a depth, corresponding to the distance between the two ring sections. The process is carried out, so that one section remains, coplanar to the body, while the other part is displaced from the body area. This part is further moved away from the body by forming, until it is mainly vertical, and forms the inner ring section. The outer section is formed by shaping the remaining main body part. ADVANTAGE - Simplified process, high precision.
