Patent DE-4040604-A1 (DE)
Inventor: BETZ DIETER DIPL ING
IPC: H01F41/02
Filed: 1990-12-19
Abstract: The aim of the invention is to improve the dissipation of the heat produced by the operation of an ignition coil (18). In contrast to a conventionally designed ignition coil, which has two formers (27), one for the primary winding (17) and one for the secondary winding (26), the different manufacturing process proposed enables the former for the primary winding (17) to be dispensed with. The primary winding (17) is wound on a mandrel (13), connected up to a connector (21) and then enclosed in the secondary winding (26) wound on its former (27). The connector (21), primary winding (17) and secondary winding (26) form a single assembly (33). This assembly (33) is transferred on to an iron core (31), which is fixed coaxial with the mandrel (13) and which has the same cross-section as the mandrel (13), by displacing it longitudinally. The iron core thus takes over the role of support for the primary winding (17) and conducts the heat produced during use directly away from the primary coil.

Title: Forming slits in fuel cell carrier for egress of process gases - applying rotating circular disk saw-blade or mill without imposing high mechanical strain
Inventor: HUG KUNO
IPC: B28D1/04
Filed: 1990-12-22
Abstract: The ceramic fuel cell carrier (1) has two channels for the process gases (4) flowing in one direction (arrow).

The sorter edges of the slits have champfered edges as a result of cutting and this assists the flow of gases through them. ADVANTAGE - Simple and quick operation while protecting material of carrier.
