The inner filter candle (12, 20) is located within the outer candle (13, 22). The assembly also has a powered (3, 5, 6, 7, 24) conveyer (2, 21), a filtrate outlet (17, 32), a com...

A method for determining the presence of an analyte in a fluid is described along with an apparatus specifically designed to carry out the method. The method involves taking a reflectance reading from one surface (15) of an inert porous matrix (11) impregnated with a reagent that will interact with the analyte to produce a light-absorbing reaction product when the fluid being analysed is applied t...

Metal lumps or pebbles are produced by introducing a molten metal stream into a stream of water in a direction which is substantially the same as the direction of the water stream and at a velocity which is substantially the same or slightly less than the velocity of the water stream.

A through pilot bore is produced with a bore head guided in the bore path along the planned tunnel course. Samples are removed from the pilot bore for geo-physical examination. The pilot bore is produced along the centre line of the planned tunnel course. In the production of the pilot bore, bore advance parameters are highlighted, which can then be related to the bore hole investigation. One or m...

A heat-sensitive substrate is coated with a first, low-temperature curing coating powder and a second, high-temperature curing coating powder. The time/temperature conditions of fusing and curing the low-temperature coating powder permit the substrate to retain its character and thus suffer no essential damage to the character of the substrate. The time/temperature conditions of fusing and curing...

The present invention relates to a method for detecting the onset of atherosclerosis and for detecting the degree of atherosclerosis.
