Patent DE-4244107-A1 (DE)
Inventor: WENDEL WOLFGANG
IPC: H05K1/16
Filed: 1992-12-24
Abstract: In a tubular-core microwave transformer (1) with printed transformer windings (5) for printed microwave circuits arranged on laminated support boards (4), it is provided in accordance with the invention that the tubular core consists of two joined half shells (2, 3) and passes with its legs (8) through one recess (9) each in the support board (4) on which the winding conductor tracks (5) are arranged integrated in the microwave circuit. This achieves both production advantages and electrical advantages: Tubular core (2, 3) and transformer windings (5) can be arranged in or on the support board (4) so that no separate transformer board and no soldered connections between the winding tracks and the associated circuit conductor tracks are needed. This provides for much simpler and inexpensive automatic production. In addition, the support board (4) requires little space. In addition, the connecting and winding conductor tracks (5, 6) have minimum lengths. Together with the gap (14) between the half shells (2, 3), this especially has the effect of significantly reducing the throughput attenuation of the tubular core transformer (1) towards high frequencies (up to 3 GHz) and thus also makes it possible to use it for the planned extension of the first satellite intermediate-frequency range for receiving the ASTRA 1D satellite. <IMAGE>

Title: Disc-type heat exchanger
Inventor: BAUMANN ANDREAS DIPL ING
IPC: F28F3/04
Filed: 1993-03-19
Abstract: Disc-type heat exchangers having discs which are stacked one on top of another and joined to one another are known, in which turbulence plates or similar are inserted between the discs in order to increase the heat exchange performance. It is disadvantageous in this case that the disc-type heat exchangers consist of a multiplicity of different individual parts. It is proposed that the discs of the disc-type heat exchanger consists of two identical disc halves which are rotated by 180 DEG relative to one another. On their top sides and undersides, the disc halves have frustoconical stampings which bear in a congruent fashion against the corresponding stampings of the respectively adjacent disc halves and are soldered to the latter. The frustoconical stampings in this case serve the purpose of joining the disc halves together in a stable fashion and act like tie-bolts. At the same time, they serve to generate turbulence both on the primary side and on the secondary side. Additional turbulence inserts are no longer required between the discs. <IMAGE>

Title: Soap bar - has grooved trough in one surface to take embedded remnant of previous soap
Inventor: KEMPA JOSEF
IPC: C11D13/14
Filed: 1993-06-02
Abstract: The bar of toilet soap has a recessed trough in its outer surface on one side, for the remains of the previous soap bar to be embedded. The trough is pref. fitted with a number of grooves to hold water, runing horizontally, packed close together so that ripples are formed between them. After the grooves have been wetted and softened, the soap remnant is pressed into the trough and the softened soap forms a plastic mass to bond the remnant and the new toilet soap bar together. The edge of the trough is structured to hold the thin edge of the soap remnant. Where the toilet bar is round, the trough is also circular, and the grooves and ripples are aligned in horizontal circles. USE/ADVANTAGE - The toilet soap structure allows the remains of previous soap to be added to it so that it is fully used, and is not discarded into the sewage system.
