Patent DE-3337924-A1 (DE)
Title: Keel with a variable profile
Inventor: ISSENDORFF HERMANN VON DR
IPC: B63B3/38
Filed: 1983-10-19
Abstract: Hitherto it has not been possible or it has only been possible to a limited extent to adapt the keel profile of a sailing boat during sailing to the respective sailing conditions. This invention solves this problem by a slender keel core being surrounded with a flexible foil, the play of which in the longitudinal direction of the boat is limited by adjustable devices. During luffing the foil forms an asymmetric profile of adjustable thickness, the buoyancy of which counteracts the drift. In the process, it bears on the lee side against the keel core and arches on the windward side in the flow like a sail in the wind. In slight or large winds, the foil is stretched by means of the device. This reduces the water resistance.

Patent DE-3345953-A1 (DE)
Title: Radiant burner
Inventor: BRUEGGEMANN REINHOLD DIPL ING
IPC: F24C1/10
Filed: 1983-12-20
Abstract: The invention relates to a radiant burner with a reflector which opens downwards. The reflector walls are opened downwards when the burner plane is arranged obliquely and are also of unequal width, the lower reflector walls being narrower and the upper reflector walls wider. It is thereby made possible to act on a very large ground surface with heat radiation, even with a very small clearance height. The heat radiation additionally heats the reflector walls, which are thus also themselves able to radiate heat. Owing to the enlargement of the upper reflector wall, its thermal expansion meanwhile also has to be taken into account. For this purpose, the upper reflector wall is already arched upwards at room temperature, so that it can no longer bend forward owing to a thermal expansion. It can only become more strongly arched upwards, so that the radiation is consequently bunched, whereas it would have become diffuse, outwards or downwards, owing to the bending which is prevented by the invention.

Title: Arrangement of a filler neck for a fuel tank in the body of a motor vehicle
Inventor: SCHEURENBRAND DIETER
IPC: B60K15/04
Filed: 1984-03-24
Abstract: The invention relates to an arrangement of a filler neck for a fuel tank in the body of a motor vehicle, the end piece of which is led through an opening, provided in a body wall section, with a radial gap and can be closed by means of a filler cap, which in its closed position overlaps the end of the filler neck and the diameter of which is smaller than the diameter of the opening. In the event of impact forces due to an accident, under the action of which the fuel tank can detach itself from its anchorage and can evade deforming body sections, such an arrangement also permits a displacement of the filler neck. When the filler neck dips away, however, the radially projecting filler cap edge frequently catches behind the annular edge of the opening and is thereby lifted or even torn off. This is prevented either by a collar conically widened on the filler neck in the direction of the filler cap and adjoining the latter, the large diameter of which collar is at least equal to that of the filler cap, or in that the opening is conically widened in the direction of the end of the neck.

Title: DC voltage source for installations for surface treatment of workpieces, especially for an ionitriding curing installation
Inventor: MATTHES HANS GEORG
IPC: H02H7/127
Filed: 1985-04-24
Abstract: The invention relates to a DC voltage source for installations for the surface treatment of workpieces, especially ionitriding curing installations. The DC voltage source consists of a parallel tuned circuit converter (U) having a low-loss parallel tuned circuit (CHS, LHS) to which an attenuating resistor (RB) (which can be disconnected) is connected, and of a bridge rectifier (B) which supplies current in the form of half cycles via a switching device (T5, T6, I, C) which is driven by a monitoring device (LE, ZS) for an arc. In the event of an arc, the switching device interrupts the current supply to the load (L) for at most one half cycle. The attenuating resistor (RB) ensures disturbance-free converter operation in the phase in which frequent arc discharges can be expected. In the phase when such arc discharges can scarcely be expected, it can be disconnected so that the converter (U) supplies current to the load (L) virtually without loss. <IMAGE>
