Title: Heating of water in continuous-flow porcelain tube - using induction heating of coaxial inner metallic tube by microwave emission from coil surrounding outer porcelain cover
Inventor: GRIGARCZIK GUNTHER
IPC: F24H1/22
Filed: 1992-01-07
Abstract: The method of heating water involves enclosing a porcelain tube on both sides and at its ends by porcelain covers stayed by a concentric metallic tube with external threads. Cold water entering at one end of the metallic tube flows through radial holes into the interior of the porcelain tube, where it becomes heated by microwaves absorbed into the metal. At the opposite end, hot water returns through more radial holes into the metallic inner tube and is drawn off. USE/ADVANTAGE - For industrial and domestic hot water supplies, easily mfd. appts. occupies little space and consumes less power for the same heating effect.

Title: Method for the production of a magnetic circuit for a valve
Inventor: STIEGLITZ PETER
IPC: H01F7/16
Filed: 1993-04-01
Abstract: In the case of already known electromagnetically actuable fuel- injection valves, a connecting ring consisting of a nonmagnetic material is incorporated in a leakproof and fixed manner between an internal pole and a valve enclosure constructed separately therefrom. The production of the highly precise individual components and the fixing of the components through to the production of the leakproof and fixed connections by, for example, soldering are complicated and cost-intensive methods. The novel method for the production of a magnetic circuit for a valve represents a particularly cost-effective variant. In this case, the one-part magnetic body is constructed in such a way that an inner internal pole (1) and an outer valve enclosure (8) are connected by means of a base (69), while outside the base (69) an axially extending annular opening (70) radially separates the internal pole (1) and the valve enclosure (8). A soldering body (72) and a nonmagnetic intermediate ring (10) are introduced into the annular opening (70). Soldering then takes place, while only thereafter is the spatial separation of internal pole (1) and valve enclosure (8) undertaken by removal of material. The fuel-injection valve is particularly suitable for fuel-injection systems of mixture-compressing, spark-ignition (external-ignition) internal combustion engines. <IMAGE>
