Title: Low-grade fuel gasification - with two rotary grate producers passing gasification gases through material for complete combustion
Inventor: KIRCHGAESSNER ERNST
IPC: C10J3/20
Filed: 1974-07-27
Abstract: Low-grade fuels such as rubbish and refuse briquettes can be turned into high-grade power gas and/or fuel gas by a gasification process with a deficiency of air, followed by a gradually progressing complete combustion. The gases produced during the gasification process are passed through the combustible material during its after combustion and are finally discharged from the process. This system can be applied to a wide variety of raw materials, from domestic refuse and sewage sludge to waste prods. from refineries, rubber/plastic industries and coal or coke dust. This prevents environmental pollution and produces fuel gas suitable for gas turbines.

Title: Current density measuring and imaging - uses measuring sensor guided through electron or ion beam to be measured coacting with shadow sensor
Inventor: ROHE KARL-HEINZ DIPL PHYS
IPC: G01T1/29
Filed: 1974-10-07
Abstract: Measuring and imaging of the current density distribution in electron or ion beams is carried out by guiding a measuring sensor through the investigated beam, while being fully or partly screened by a moving shadow sensor so that the shadow line projected onto the measuring sensor moves along the same. This actuates a time variation of the sensor current representing a rate of the current density at the location of the shadow line of the measuring sensor. This variation is used for imaging representation of the spatial current density distribution in the beam in the form of a voltage, proportional to the current time related variation. This voltage controls the brightness-dark relation of the imaging system.

Title: Oil mist generator for airline lubrication - has eddy current chamber to supply oil mist to metering valve
Inventor: BEREIT ARNOLD
IPC: F16N7/34
Filed: 1975-02-28
Abstract: An oil mist generator which is used to lubricate a compressed air line receives its oil supply from a metering valve. The output of the metering valve is governed by the pressure in the air line. Oil from the metering valve is forced passed a non return valve into a chamber where eddy currents produce oil mist formation. The communicating vernturi shaped air line causes the oil mist to mix with the flow of compressed air. A small channel leads from upstream of the generator to the oil reservoir to pressurise the supply.

Title: Re-touching pictures from electronic scanner - corrections are marked on original by fluorescent or absorbent substance
Inventor: PUGSLEY PETER CHARLES
IPC: H04N1/40

Abstract: The pictures are reproduced with the aid of a sequence of signals from an electronic scanner. No mask is required the corrections being marked on the original, using substances which either fluoresce under ultra-violet light or absorb infra-red light. When the scanner is used with a suitable light source, the correction markings give signals outside the normal range; alternatively, an additional scanner, operating in advance of the main one, may be used. In either case the correction signals are distinctive; and they are used to produce substitute signals not only for the corrected picture element but also for close elements.
