Abstract: The invention is directed to a process to bacterially decompose organic waste, material to a digested material in a digesting tank by mixing the organic waste material with aerobic bacteria at a temperature of between 40 C and 70° C. while supplying between 0.5 and 10 m3 of air per hour per kg of the total of organic waste material on a dry basis and digested material on a dry basis and discharging from the digesting tank a humid air stream.

Abstract: A resiliently flexible planar pourer (104) rollable into a tubular pouring shape suitable for placement into a mouth (400) and neck (402) of a vessel (100) to define an operating condition wherein it provides a flow path from the vessel (100) and wherein the pourer (104) presses against side walls of the neck (402) under its own resilience. The pourer (104) comprises an obstruction tab (106) foldable towards an obstructing condition wherein it projects towards an interior of the tubular pouring shape when the pourer (104) is in the operating condition so as to obstruct the flow path. The invention extends to a label comprising a body with a pourer (104) incorporated therein.

Abstract: A coal processing operation (10) includes in a dense media separation stage (12), subjecting a coal feedstock (18) which includes minerals to dense media separation producing a first coal stream (20) and a second coal stream (22). Coal in the first coal stream (20) is lower in ash and has a lower ash fusion temperature than coal in the second coal stream (22). Coal from the first coal stream (20) is processed in a high temperature coal processing operation (44), and coal from the second coal stream (22) is processed in a medium temperature coal processing operation (16).

Abstract: Method of operating a fixed bed dry bottom gasifier includes feeding coarse particulate coal with an average particle size of at least 1 mm and an ash fusion temperature increasing agent into a gasification chamber of the gasifier to form a coal bed, feeding a gasification agent into the gasification chamber, and gasifying the coarse particulate coal in the gasification chamber to produce synthesis gas as well as ash. The ash is collected in an ash bed below the coal, and the synthesis gas and the ash are removed from the gasification chamber.

Abstract: Described is a coagulation solution suitable for causing coagulation of a collagen-containing casing of a co-extruded food product. This coagulation solution comprises a highly soluble inorganic salt. The pH of the coagulation solution is adjusted using a buffer solution. Also described is a method for coagulating a collagen-containing of a co-extruded food product. This method comprises the step of bringing the collagen casing into contact with a coagulation solution. The coagulation solution herein comprises a solution as described above.

Abstract: For correcting axial errors of a tool, the latter is held by a two-part tool holder, whose two parts are reciprocally displaceable by a setscrew along their engaging interfaces at right angles to the axis. For this purpose, the locking screws of a flange connection are correspondingly loosened. The axial correction can be simply and rapidly performed, in that the setscrew is provided on a setting ring rotatable about the axis.

Abstract: A coolant and lubricant is supplied to the cutter head through the shank of a reamer. For this purpose an axial channel extends through the reamer shank and encloses in its front part a conical screw used for adjusting the cutter head and whose threaded shank has at least one longitudinal slot, so that the coolant and lubricant passes through the threaded shank into a ring channel in the front region of the reamer. The coolant and lubricant flows from said ring channel via outlet channels between the cutters. The outlet channels slope outwards in the direction of the leading edge of the cutters, so that an optimum cooling and lubrication of the latter is obtained.
