Patent DE-4221528-A1 (DE)
Inventor: VIESMANN HANS DR
IPC: F24H1/28
Filed: 1992-07-01
Abstract: The invention relates to a residual heat exchanger for mounting in the boiler casing, consisting of a water-conducting and a gas-conducting inner space, which spaces are separated from one another by walls extending parallel to one another and wound spirally round a packing and are closed with respect to one another by edges bent at right angles. To construct such a residual heat exchanger in a special configuration such that the components involved can be dimensioned as thin as possible, taking into account the winding process, the whole nevertheless being sufficiently pressure-resistant in the finished state, that separate spacers not actually belonging to the heat exchanger can be dispensed with, and that, lastly, during the winding process to a spiral the edges to be connected by welding are unable, or virtually unable, to be distorted in undulating fashion and also the wall faces are unable to be deformed, the residual heat exchanger according to the invention is constructed in such a way that the inner wall (1), in relation to the winding axis (WA), has edges (4) which are bent outwards at right angles at the top and bottom and correspond maximally to the width (B) of the water-conducting inner space (3), and the outer wall (2) has edges (6) bent inwards at right angles and of maximally half the width (B), which edges (6) cover over the edges (4) of the inner wall (1) or are aligned therewith and are connected thereto in a fluid-tight manner. Undulating embossed portions (7) of both walls (1, 2), facing into the gas-conducting inner space (3') which is open to the inflow and outflow side, are arranged, in mutually supporting fashion, at a distance (D) from the edges (4, 6) in the walls (1, 2) substantially parallel to the winding axis (WA). The water-conducting inner space (3) at both ends of the spiral is closed, except for the forward and return connection openings. <IMAGE>

Title: Coil with metallic core integrated in semiconductor device - uses 3 metallisation layers which are selectively interconnected
Inventor: LEE KYUNG SOO
IPC: H01L27/04
Filed: 1992-07-10
Abstract: The semiconductor device contains a coil featuring a lower and upper metal layer which enclose a middle metallic layer which is insulated from the other 2 layers by a dielectric coating. The central layer represents pref. a core and is made of magnetic metal pref. Ni. The lower and upper metal layer are interconnected along the side of the middle metallic layer through contacts etched in the dielectric layer. They form pref. the windings of the coil. The width of the upper and lower metal layer are the same, that of the middle layer is less. In prodn. on a semiconductor substrate an insulating layer and a metal layer are deposited. The metal layer is etched to provide a pattern. Then a dielectric layer is deposited and etched to provide contact windows near the edges of the metal layer. A second metal layer is deposited and etched to provide a central layer, centrally on top of the first metal pattern, not connected to the contacts and to leave metal in the contact windows etched in the dielectric layer. A third dielectric layer is deposited and etched to cover the central metal layer completely and to open the previously defined contact windows. Then a third metal layer is deposited and etched to the same size as the first metal layer and aligned with this. The structure is then protected by a final passivation layer. USE/ADVANTAGE - The structure forms a coil with a central metal core which can be made of a magnetic material. The device can be integrated with a semiconductor device and form a magnetic sensor to generate a magnetic field.

Date Jun. 23, 1994The present invention proposes adding an alkaline solution or a mixture of two or more alkaline solutions to the agent system of absorption machines operating with ammonia or methylamine as the agent and water as the solvent. This addition of an alkaline solution or an alkaline solution mixture has a number of advantageous effects. These are, i.a. 1. The dissolving respectively expelling heat of the agent is reduced, raising the output figure. 2. The agent vapor generated is very pure. A dephlegmator is obviated. 3. The alkaline solution makes steel surfaces inert when sealed from air and in a high vaccum, thereby obviating corrosion inhibitors. 4. The viscosity of the solvent is reduced, decreasing pump operation.

Patent DE-4301927-A1 (DE)
Inventor: TSUNO NOBUO
IPC: B23K26/36
Filed: 1993-01-25
Abstract: In a bonded metal-alumina material, a reaction layer at least including spinel, and possibly alumina, magnesia. aluminum and oxygen is formed on their bonded interface. In the method for producing the bond while the surface of the alumina element is in contact with the metallic element, in which element at least the surface to be banded to alumina is made up of an Mg-containing alloy layer, the elements are heated at a temperature equal to or lower than the solidus of said alloy layer and then pressed together for banding. The resultant bonded interface is excellent in resistance to Na attack, because bonding takes place at a temperature not higher than the solidus and the bonded interface is made up of spinel, alumina, magnesia, aluminum, and so on, which are excellent in corrosion resistance to Na attack.

Inventor: MATHIAS RAINER
IPC: E06B9/90
Filed: 1993-06-19
Abstract: A braking device is provided for a moving part, such as a roller blind or the like, provided in a vehicle. In the basic condition, the moving part is preloaded in a preferred movement direction. The braking device comprises a rotating part which can be braked and which can be connected in terms of motion to the movable part. The braking device is produced and designed in such a manner that it acts on the moving part in the direction of the preferred movement direction, in which the device is preloaded, and produces a braking force for braking the movement of the moving part. However, the braking device can be decoupled in the opposite movement direction of the moving part. A braking device of this type can be used in a preferred way in a sun-roof blind, a roller blind or the like. The braking device operates expediently as a rotational movement brake, the braking effect being able to be generated on the one hand in cooperation with a viscous mass or alternatively in cooperation with an air stream.

Title: Dirigible kite which can be used as an item of games and sports equipment
Inventor: GRAICHEN SONJA
IPC: A63H27/08
Filed: 1994-02-22
Abstract: Hitherto, only rigid frame constructions have been used as dirigible kites. In the case of these kites, there is only a limited size range within which they are sufficiently aerodynamic and mechanically stable to be able to fly under all wind conditions. The new model is intended to have good aerodynamic and mechanical properties irrespective of size. The dirigible kite is therefore divided into a rotor which provides lift and a stator which is responsible for stability and dirigibility. The two parts are connected to each other by strings and rods. Dirigible kite, which is more stable and has better and more sensitive dirigibility than those known hitherto.
