Title: Method and apparatus for indicating the wear of hydraulic systems
Inventor: BOROWSKI KARL-HEINZ DR ING
IPC: F16H61/40
Filed: 1985-08-23
Abstract: The invention relates to a method and to the associated apparatus for indicating the wear of hydraulic systems. These have a closed working circuit (1) which is equipped with a fluid pump (2) and a fluid motor (3), to which a constant volume of fluid is continuously fed and from which a corresponding volume of fluid is withdrawn. To detect the wear, the invention proposes that the volume of fluid fed and withdrawn from the working circuit (1) be continuously measured, the difference in the measured value of the two volumes be indicated and - since this indicates excessive leakage losses - that this difference be used to trigger a signal when a critical value is reached. <IMAGE>

Patent DE-3531418-A1 (DE)
Title: Ball transformer
Inventor: DUERING JUERGEN
IPC: H01F30/08
Filed: 1985-09-03
Abstract: In conventional transformers, a relatively large amount of heat is released in the iron core. Instead of this, I wind two wires like a ball and omit the iron core. The first wire induces an opposing electrical field in the second wire, in accordance with Coulomb's Law. The wires are located spatially with respect to one another such that their cross-section results in a chessboard-like pattern: the one wire is black, the other being white. Since I short-circuit one wire to itself, I can achieve different voltages.

Title: Process for the addition of reducing agent in the simultaneous removal of SO2 and NOx
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1985-12-24
Abstract: It is known to add reducing agents to the simultaneous removal of SO2 and NOx from the flue gases of boilers fired with fossil fuels in order to convert the iron(III) forming in the iron chelate process back into iron(II). It is known to add the reducing agent in the form of a powder or as a paste in glycol. The addition in powder form has the disadvantage that it is difficult to transport, whereas the addition as paste has a disadvantageous effect on the water treatment process. In order to eliminate these disadvantages, it is proposed according to the invention that the reducing agent be incorporated in an oily composition and be made pumpable and, after the consumption of the reducing agent, be sucked off at the surface of the scrubbing liquid and the oil have a specific gravity which is smaller than that of the scrubbing water.

Title: Optical collision prevention device
Inventor: SNAPER ALVIN ALLYN
IPC: B60Q7/02
Filed: 1987-08-28
Abstract: An optical collision prevention device for attachment to a vehicle, in particular aircraft. The device responds to pulsating light sources whose light is within a selected frequency band and in particular to the frequency of aircraft light sources which are clocked and to rotating beacon light sources. In contrast, the device disregards all the other light sources such as continuous natural light sources, manmade light sources such as street lighting and ground lighting sources. The device perceives pulsating light sources on aircraft or ground vehicles within the vicinity of the light sources (transmitters) and produces a visible and audible alarm for pilot or driver. The alarm is given if another vehicle, in particular aircraft is located within the detection range which typically has an elliptical shape around the transmitter (the light source) in all directions with a detection range of up to approximately 5 km. The device is intended to perceive clocked or rotating beacons (strobe or rotating beacons) whose frequencies are standardised by national regulations (U.S. Federal Regulations) according to which it is also necessary for such light sources to be lit at any time during a flight. The collision prevention device has an optical detector for visible pulsating light sources, a detection prevention device for suppressing signals of undesired light sources, a ...
