Patent DE-3927493-C1 (DE)
IPC: D05B27/04
Filed: 1989-08-21
Granted: 1990-12-13
Abstract: The invention relates to a sewing machine with a rotatably driven upper feed system, the drive movement of which is derived from a drive shaft (1) via a clutch coupling. The clutch coupling essentially consists of a sleeve-like driving component (8) on the drive shaft (1) and a driven component (9) arranged coaxially therewith which drives the feed system (24) (Fig. 4), and a helical spring (7) providing the power connection between the two components which can be controlled via the axial movement of the changeover component (15). As the clutch coupling permits the transmission of forces in the axial direction, the feed system (24) arranged on the driven component (9) via the assembly (23) bears on the material to be sewn with a predetermined pressure even in the uncoupled position and is freely movable in both directions of rotation. The securing system of the assembly (23) on the material pressure rod (25) also facilitates the lifting of the feed system (24) off the material to be sewn.

Title: Resin impregnation for sewer pipe lagging - involves unimpregnated lagging located in pipe with resin dosing unit and vacuum pump to draw resin through lagging
Inventor: SCHMIDT MANFRED
IPC: F16L55/165
Filed: 1993-03-03
Granted: 1994-04-21
Abstract: The method is for impregnating a sewer pipe lagging with a plastics resin. The lagging comprises an inner sheet and an outer sheet encapsulating a glass fibre mesh. The unimpregnated lagging is introduced into the sewer pipe with blocking ends placed at either end of the lagging. The lagging is then inflated and the resin unit placed at one end in the space between the layer sheet. A vacuum pump is then arranged at the other end of the lagging and operated to draw the resin through the glass fibre mesh. Curing of the resin occurs by applying an energy source. USE/ADVANTAGE - Ensures full impregnation of glass mesh with plastics resin for lagging of sewer pipe, and avoids shrinkage.
