Patent DE-3606353-A1 (DE)
Title: Device for generating electric energy by means of wind power
Inventor: FEDDERSEN HANS PETER
IPC: F03D11/04
Filed: 1986-02-27
Abstract: Devices for generating electric energy by means of wind power have so far required expensive braking and disconnection means once the wind force has reached a predetermined upper magnitude, in order to prevent destruction of the devices. These braking and disconnection means are very vulnerable, and failure generally leads to complete destruction of the device. In order to eliminate this deficiency, a device is proposed such as automatically sets itself to different wind speeds without requiring to be manipulated in any way by operators and without the need to provide braking and arresting (locking) means. For this purpose, the mast-like frame of the device (10) on one end of which a rotor (12) having rotor blades is arranged is subdivided into a first fixed frame part (110) standing on a base (16) and a second frame part (111) which can be pivoted essentially vertically about an axis (17) on the first frame part (110). The rotor (12) is arranged on the free end of the second frame part (111), on the end (111) thereof pointing away from the axis (17). When the wind impinges strongly, the second frame part (111) swivels towards the base (16), and when the wind is incident less strongly is in turn aligned away therefrom in the direction of its upright normal position. <IMAGE>

Patent DE-3622494-A1 (DE)
Title: Contact system for an electrical gas-blast circuit breaker
Inventor: VEUHOFF FRIEDRICH-WILHELM
IPC: H01H33/70
Filed: 1986-07-02
Abstract: In the case of a contact system for an electrical gas-blast circuit breaker, erosion can occur at the coupling points (8) of the ends of the contact fingers (4) facing a switching element (2) during the switching operations, as a result of an arc being struck. In the switched-on stage, the current must flow via these points (8) which can be influenced by erosion. Under specific operational conditions, this can lead to an adverse effect on the contact properties. In order to avoid this problem, in each case one additional coupling point (9) is arranged on the contact fingers between the coupling points (8) and further coupling points (7) which face a second switching element (1), such that the distance (A) of the additional coupling point (9) from the coupling point (8) which can be influenced by erosion is somewhat larger than the isolating path (T). The additional coupling points (9) are thus not influenced by an arc occurring during a switching operation. Two coupling points (7, 9) are thus available on each contact finger (4) for the current flow, which coupling points remain free of erosion and thus always ensure optimum contact conditions. <IMAGE>

Title: System for feeding lubricating fluid and/or cooling fluid to a container
Inventor: JORDAN BERNHARD
IPC: B60R16/08
Filed: 1986-11-14
Abstract: The pumping of very cold lubricating or cooling fluid is associated with very high losses. The intention is to create a system for feeding cooling fluid to a container with internal heat generation which guarantees rapid heating of the cooling fluid to operating temperature. For this purpose, the pipe conduit leading to the container (housing 4) consists on the pump side of a vertical pipe section 15, the upper end of which lies a certain distance above the level of the lubricating fluid in the container in order to produce a certain static pressure and which has a free bypass to a second container (housing 1) for excess lubricating fluid. Connected to pipe section 15 is a further pipe section 16 composed of thermally conductive material which has a smaller inside diameter and wall thickness than the first pipe section 15 and is laid in the container 4. The dimensions of the pipe conduit are matched to one another in such a way that the lubricating fluid in pipe section 16 assumes the temperature of the lubricating fluid situated in the container 4 and flows into the container 4 under the influence of the static pressure. The feed system regulates the flow of lubricating or cooling fluid to the container without the use of active control means. In the case of very high viscosity of the lubricating or cooling fluid, there is virtually no flow, with the result that the excess lubricating or cooling fluid can flow off via the bypass and the pump 12 is largely relieved of load. <IMAGE>
