Title: Automatic seam cutting line control - involves electronic processing of chisel forces, insensitive to interference, with time units
Inventor: RIECKHOFF JUERGEN ING GRAD
IPC: E21C35/00
Filed: 1978-07-20
Abstract: Different chiselling forces metered by two chisels are recorded, in the process, for automatic regulation of the cutting datum line of a roller-cutter-loader, according to the course of the seam. In this processing, signals during a firmly predetermined gate period are scanned, using time units, and evaluation remains insensitive to interference outside this period. This method ensures that the movement of the rollers is controlled only when the peaks of the cutting force registered emanate from the seam roof or floor.

Title: Removing gas and fluid from coagulated viscose hose - and introducing lining forming fluid without lengths of waste
Inventor: STENGER KARL
IPC: A22C13/00
Filed: 1979-08-24
Abstract: Media capable of flowing are removed from or introduced into the interior of a hose, esp. of fibre-reinforced cellulose hydrate. At least one passage is formed in the wall of the hose and the media capable of flowing are passed through this, either into or out of the interior. The passage or passages are then closed by covering. A piece of an integral hose section is laid flat by pressing it together on a support having a horizontal flat surface. In the free wall of the flat, supported piece of hose, at least one opening is made, and media capable of flowing are put in or withdrawn from it. A covering section of film, free from adhesive, is introduced from outside into the cavity of the flattened hose section and is applied to the inside of the hose wall so as to cover the opening. The passage is then closed by a section of film coated with an adhesive. This film is pressed against the hose wall where it overlaps the opening and against the covering piece of film in the cavity of the hose so that it adheres. For pref. the adhesive is an alpha cyanacrylate polymer possibly with isocyanate or epoxy compounds added. The covering film is cellulose hydrate. Improves the existing techniques for the production of continuous hoses of cellulose hydrate from viscose so that fluids and gas collecting inside can be removed, and if necessary a fluid for forming an internal coating inside the tube can be introduced, without wasting a large amt. of hose.
