Title: Insulation stripping machine for electric cables - has rotating brushes also revolving around common centre driven by planet gears
Inventor: MARTER JOSEF
IPC: H02G1/12
Filed: 1975-09-13
Abstract: To strip the insulation, protective coating, or oxide film (2) from a conductor (3), rotating wire or glass fibre brushes (1) are employed. These brushes also rotate about a common centre so that the whole brush system revolves around the conductor which remains stationary. In this way the insulation layer is removed evenly. The brushes are typically driven by an adjustable planet gear which allows setting of the spacing to suit the conductor. The brushes may be shaped to clean the conical ends of conductors, for example before sweating or welding into connecting ferrules. Wire diameters above 5mm can be cleaned by this process and layer thicknesses up to about 5mm removed satisfactorily.

Title: Air pollution concentration profile measuring system - uses several radiation beams emitted from aircraft directed onto earth surface and reflected beam evaluation
Inventor: ENGLISCH WOLFGANG DIPL PHYS
IPC: G01S17/95
Filed: 1976-02-21
Abstract: The vertical concentration profile of air pollution or normal constituents of the atmosphere is measured from an aircraft using the comparative absorption principle. Several colinear light beams are directed on to the earth's surface, the diffusely reflected light from the surface is then detected and the concentration of given constituents is derived by comparing the reflections produced by the various beams. At least two multiple beams (3, 4) each comprising several colinear beams, are directed onto the earth's surface (5) at a given angle having a component a in the flying direction. The reflections from the beams are detected separately, and the vertical concentration profile is determined from an equation, including the flying speed, the flight altitude and the time lag between detection of the air constituents by the beams.

Patent DE-2739618-A1 (DE)
Title: Organic fertilisers - contg. coffee-bean and/or ground-nut skins
Inventor: FINKEN HERMANN ING GRAD
IPC: C05F11/00
Filed: 1977-09-02
Abstract: New organic fertilisers contain coffee-bean skins and/or groundnut skins. The fertilisers make use of materials that are otherwise regarded as waste and are difficult and/or expensive to dispose of. The nitrogen content of coffee and groundnut skins is released slowly to plants. The nitrogen content of coffee and groundnut skins is ca 2%. Initially, part of this nitrogen content is utilised by soil cellulose-decomposing bacteria, but as soon as the cellulose has been consumed the bacteria die and bacterial nitrogen is released into the soils. Thus, if fertilisers consist solely of coffee and/or groundnut skins, the onset of nitrogen release to plants is slow. If on the other hand the skins are mixed with a fast-acting nitrogenous fertiliser (e.g. urea), nitrogen release to plants is sustained from the time of application up to exhaustion of the cellulose content of the skins.

Title: Coal dust gasification - by injecting with oxygen and steam in fluidised carbonaceous bed
Inventor: FLESCH WILHELM DIPL ING DR
IPC: C10J3/54
Filed: 1977-11-21
Abstract: Pulverised coal is gasified by maintaining in the gasifier a fluidised bed of granular carbonaceous material and by contacting the flow of pulverised coal and gasifying agent with it. The products of reaction in the flow thus are projected into a fluidised bed and can react once more with the incandescent fluidised material before they leave the reactor. Process eliminates the risk of oxygen breakouts and converts undesirable gas components into fuel gas. The residue is discharged dry with the bed remnants, thus avoiding the difficulties with fused ash.
