Title: Heat exchanger for domestic heating system - has dividing wall with large surface area for maximum heat transfer
Inventor: KLIX UWE
IPC: F28F21/04
Filed: 1980-08-12
Abstract: The heat exchanger is designed to improve the efficiency of the heating system of a dwelling house. The heat exchanger consists of a duct of square cross-section divided into two separate passages by an internal wall. This wall has a zig-zag form so that the surface dividing the two passage-ways has the greatest possible area. The duct passes through the wall (16) of the house with one of the passage-ways allowing air to flow into the house whilst the used air flows out through the other passage-way. Fans (17) are fitted in the inlet and outlet ducts (2) to maintain the flow of air so that the outgoing warm air gives up heat to the incoming cool air. In addition to square section ducts, circular section ducts can be used with a variety of internal walls.

Title: Tensioning frame for embroidery, etc. - has wall which tip outwards under action of eccentrically mounted push-rods
Inventor: STEIDLE GERHARD
IPC: D06C3/08
Filed: 1980-08-27
Abstract: A tensioning frame for hand embroidery work comprises a rectangular box of four vertical plates having rows of pins along the upper edges. The plates are joined together at their lower edges by elastically-yielding connectors which allow the plates to tip slightly outwards to tension the fabric held on the pins. Midway along each of the walls is attached a push-rod, whose other end is linked eccentrically to a disc in the centre of the box, which can swivel about a vertical axis. An operating lever integral with the disc projects through a slot in one of the plates which allows a limited movement of the lever, causing the disc to swivel such that the push-rods exert an equal outward force on all the walls to tension the fabric evenly. This is a simple, inexpensive device which does not require a large operating force.
Patent DE-3032802-A1 (DE)
Title: Load regulated brake pressure control - has brake pressure controlled by bellows controlled by pressure valve piston connected to air spring bellows
Inventor: FAUCK GERHARD
IPC: B60T8/22
Filed: 1980-08-30
Abstract: The brake pressure regulator controls the brake pressure by the pressure in an air bellows. A member on the bellows has its free end sliding on a control slope on the control piston operated by a regulator valve, connected to the vehicle axle air springs so that when the vehicle is unloaded the member is at the lowest point on the slope. As the vehicle is loaded the control piston moves to lift a member by the control slope thereby increasing pressure in the bellows and thus brake pressure. This ensures correct brake pressure when unloaded and loaded.

Title: Process and apparatus for producing sponge iron
Inventor: SANTEN SVEN
IPC: C21B13/02
Filed: 1981-02-07
Abstract: In a process for producing sponge iron by continuous reduction of iron oxides in a blast-furnace (shaft furnace), the reaction gas is removed from a blast-furnace, essentially the entire CO2 and H2O is removed from this reaction gas, and the reaction gas is divided into at least two part-streams. One of these part-streams is fed to a gas generator which has a plasma burner and devices for injecting a solid reductant and an oxidant, this reaction gas being heated by the plasma burner, and the heated gas being injected with the solid reductant and the oxidant in order to form an intermediary gas mixture, which mainly consists of CO and H2. In the process, said intermediary gas mixture is held at such a temperature that the ash contained in the solid reductant forms a slag. This intermediary gas is mixed with at least one of the other part-streams in such a ratio that the temperature of the resulting reduction gas is suitable for reducing iron oxides in a blast-furnace. Said reduction gas is injected into the bottom part of a blast-furnace and is passed upwards through the blast-furnace, which makes it possible to reduce iron oxides in the blast-furnace. The reduced iron is drawn from the furnace. The invention also comprises an apparatus for carrying out the process. <IMAGE>

Patent DE-3140018-A1 (DE)
Title: Tear-open closure for closed surfaces
Inventor: GOLLER KLAUS
IPC: B65D75/58
Filed: 1981-10-08
Abstract: The tear-open closure is conceived for multi-point opening of a (packaging) surface and is explained below by the example of use as a portion package. A cushion-shaped, flexible film package which is closed on all sides is fitted with the tear-open closure on one surface. For this purpose, the closure surface (2) and the tear-open surface (1), located above it, are connected to one another at many points. These connection or fusion points (6) are the "intended opening points" of the package and expose the surface perforation (5) when the tear-open surface has been removed. By means of the surface perforation (5), the filling medium (3) located in the package can be applied easily and evenly to a surface to be treated. If protection is required, the hand of the person applying the filling medium does not need to come into contact therewith or with the surface to be treated (for example skin treatment/hospital) since the hand presses onto the closed rear side of the package. Use is also possible in other sectors, for example packages for perfume or aromatic substances. When the tear-open closure has been opened, the active substances emerge through the surface opening. (Moth powder, portions for refreshment or cleaning). Advantages of the tear-open closure are: cost-effective and material-saving due to punctiform fusion of two sheets of film, simple handling since opening takes place by pulling off the tear-open surface and closing by folding back the tear-open surface, areal outlet of the filling medium is achieved by the randomly high number of outlet openings, protective effect as the hand used is not at risk since there is no contact with the filling medium nor with the surface to be treated in the case of hazardous applications. <IMAGE>
