摘要： Method and apparatus for determining both relative speed between two bodies and length measurement of linearly moving material (21), particularly of moving strip or sheet material. A pair of non contacting detectors in a sensing head (11) derive two time sequences of signals characteristic of physical variations of material passing through two locations spaced apart (d) in direction of movement. The time delay between the two sequences of signals for which the two sequences most closely match one another is determined by a correlation unit (12) as a measure of time for material to travel between the two said locations to provide speed determination on a speed display unit (14). Length determination is made by determining instantaneous material speed values (by above-mentioned method) throughout a time interval during which the material passes the detectors and integrating these speed values over the time interval to obtain the length of material.

摘要： Deashing of coal is achieved by oil agglomeration and subsequent separation of a carbon oil phase. The oil is removed by steam stripping either simultaneously and/or after the coal oil agglomerates have been disintegrated. The fine coal product can be used in steam generating plants such as power stations.

摘要： Method of forming a furnace cooling element involving casting a metal block or plate (10) around one or more elongated metal tubes (11) which have a protective coating applied thereto, and thereafter the, or each, metal tube (11) is explosively expanded by an explosive charge (12) closer to the surrounding material of the metal plate (10). Also disclosed is a method in which the protective coating on the metal tube is replaced by a full length external shroud tube (21) to increase the thermal efficiency of the cooling element, the inner metal cooling tube (20) is explosively expanded by an explosive charge (23) closer to the surrounding shroud tube (21) prior to casting a metal plate or block (28) around the tube combination (20, 21) to minimise the gap (22) between the outside wall of the metal cooling tube (20) and the inside wall of the metal protective shroud tube (21). Following casting the metal plate or block (28), the metal cooling tube (20) is again explosively expanded closer to the protective shroud tube (21) by a further explosive charge (23').
