Title: Sausage filling machine - having vent valve in piston and protective cover on front to prevent filling entering valve but allowing air to vent
Inventor: BOCK ALOIS
IPC: A22C11/04
Filed: 1979-04-24
Abstract: Sausage filler has a piston with a vent valve. On the lower surface of the piston a cavity is formed into which is fitted the element of the valve. The element has a stem which is free to move up and down over a limited distance, having an O ring and a flexible cover. The stem passes through a hole in the piston and terminates with a shank of larger dia. This shank seals the opening when the element is down and allows the piston to suck back sausage mixture left in the outlet pipe. When descending, the valve allows air to pass but once in contact with sausage mixture the flexible cover pushes the element up into the cavity and the "O" ring seals it. Used for manufacture of sausages esp frying sausages. Allows material left in the discharge line to be drawn back into the cylinder, giving tight seal and needing infrequent cleaning.

Title: Heat-reflecting wallpaper - has metallic layer on carrier with protective layer and outer cladding (NO 3.11.80)
Inventor: AISSLINGER DIETER E
IPC: D21H27/20
Filed: 1979-07-17
Abstract: The metallic layer on the carrier, to form the heat-reflecting wallpaper material, to reflect IR is thinner than 30 nm, and there is a protective lacquer over the metal layer of several microns thickness giving a protective and/or adhesive function. There is an additional outer coating of several 10 microns thickness, which is transparent in the 4-20 microns wave length region, but appears coloured in the range of lambda 0.4-0.8 microns. The carrier can also be of a special paper, supporting the metallic and lacquered layers, pattern bonded to wallpaper with adhesive. The patterned adhesive layer is sufficiently elastic to make the paper layers flexible, and reduces the paper's flammability, while the metallic layer prevents the escape of alkali matter from the wall. PVC is preferred as the plastic layer.. The material gives a good heat reflection performance, while offering a pleasant appearance and handle, avoiding problems of the electrical conductivity in the metallic layer.

Title: Carpet tufting process with versatile patterning capability - uses hollow needle to draw individual tuft lengths through backing
Inventor: SCHOLZ HARTMUT
IPC: D05C15/06
Filed: 1979-10-02
Abstract: A process for the production of tufted carpeting, and a machine for performing the process, uses a hollow needle which penetrates a backing fabric from the underside. One of a selection of pile yarns of different types or colours is presented to the needle, is drawn inside by suction or by a mechanical gripper, and is drawn through the backing as the needle withdraws. The yarn is severed at the required pile height; relative movement occurs between backing and needle, and the needle penetrates the backing anew, taking with it the end of the new tuft, which pulls out of the needle as it advances.. The needle function is limited to that of looping the tuft through the backing, and specialised mechanisms are provided to deal with yarn selection and transport. This eliminates the patterning limitations of previous tufting processes. The action of the needle protects the yarn from damage as it is drawn through the backing fabric.
