Title: Vehicle which takes off from water
Inventor: JOERG GUENTER DIPL ING
IPC: B60V1/22
Filed: 1987-09-08
Abstract: A vehicle is described which takes off from water, floats on wings and is able to use the ground effect during take-off and has at least one mainplane which is designed as a hollow body which is segmented into chambers. These chambers can be provided with flooding and draining devices and form the wings of the vehicle. The central part of the trailing edge of the mainplane, which is immersed more deeply in the water in the floating position than its outer regions, has a wedge-shaped sliding surface, which is arranged centrally between the wings which form the mainplane. The sliding surface projects beyond the underneath of the plane of the mainplane at the trailing edge of said mainplane, and runs with a slight inclination towards the front and merges flush into the plane of the mainplane. The trailing edge, which is composed of the edges of the two wings and those of the sliding surface, runs parallel to the inner edge of the mainplane. Only the corners of the trailing edge are bent, and the inclines thus formed connect the trailing edge to the wing sides and to the end plates which, in the case of tandem vehicles, connect the wings which are arranged one behind the other.

Title: Method and circuit arrangement for protecting a speed-controlled washing machine drive motor
Inventor: FISCHER MICHAEL DIPL ING
IPC: D06F34/08
Filed: 1987-12-21
Abstract: An electrical washing machine drive motor (3) whose speed is controlled by means of a controlled semiconductor (8) is intended to be protected against free acceleration in the event of the semiconductor being short-circuited. Washing machines with a spinning function have a speed controller which is influenced, inter alia, by a device for detecting unbalance. In order to avoid damage in the washing machine, the maximum speed is intended to be limited if the semiconductor is short-circuited and the unbalance detection device can in consequence no longer limit the speed. To this end, the correct operation of the semiconductor (8) is monitored and, if an internal short-circuit is found in the semiconductor, the setting for the low final speed is electrically interlocked. <IMAGE>
