Abstract: @ A winch drum (1) is designed to operate without fleeting knives.The winching surface of the drum (1) is made up of fingers (6) which reciprocate axially along the drum (1) during use. The design is such that, in use, a major proportion of the fingers (6) are always moving in the same direction along the drum (1). This has the effect that the turns of an element being winched are both spaced and continuously progressed along the winching surface of the drum (1).The invention has particular application in the laying and taking up of submarine optical fibre cables.

Abstract: On woodworking machines of the traversing type, for example those used for sanding operations, the items (23) are secured on a vacuum conveyor (3). When the items are not perfectly plane, or when the contact surface against the conveyor is small, the holding power is often not sufficient to allow satisfactory processing operations to be effected without the time-consuming use of devices such as clamping tools or the like. In order to overcome this disadvantage, the machine according to the invention is provided with a number of compressed air nozzles (10) which direct a stream of air towards the items (23), whereby there is achieved a hitherto unknown degree of good retention, even of items which have not hitherto been able to be secured by means of air alone. The nozzles (10) are connected to the pressure side (9) of the air pumps (6), and the suction of the conveyor (3) is connected to the pumps' inlet sides (8), thus hereby creating a closed system with good economy. Finally, there is a reduction in the friction of the belt (13) as well as the wear on the supporting plate (18), this being the result of the formation of eddy currents in some grooves (20), which are formed in the plate (18) and through which the air is sucked. <IMAGE>

Abstract: The invention concerns a method for the transfer of a measurement signal from a revolving roll used in the making of paper. In the method, detectors (5) are employed, which have been arranged over a certain width in the transverse direction of the roll (10), preferably as uniformly spaced, the measurement signals received from said detectors being passed to a unit (2) for reading and measurement of the detectors, which unit is installed preferably at the end of the roll (10). From said unit, the signals are transmitted wirelessly further as telemeter signals to a reading unit (3), which is placed outside the roll (10) and which is connected to a PC (7) or to an equivalent computer. In the unit (2) for reading and measurement of the detectors, a transponder in itself known is used, into which a code of its own is coded for each detector (5). The signals are processed in the whole measurement process as analog signals, and, in the transfer of the telemeter signals between the unit (2) for reading and measurement of the detectors and the reading unit (3) placed outside the roll (10), a substantially low transfer frequency of an order of 100...150 kHz is employed. The invention also concerns an equipment for the transfer of a measurement signal. <IMAGE>

Abstract: A method of preventing corrosion in boiler-plant equipment when cooling flue gases originating from a combustion plant, such as flue gases containing sulphur oxide or organic acids, to a temperature beneath the acid dew-point of the gases, in a cooler having heat-exchanging walls. The flue gases are passed to the cooler at a temperature above the acid dew-point. Those surfaces of the heat-exchanging walls, over which the gases flow, are held at a temperature beneath an upper permitted wall-temperature, in respect of the material from which the walls are made, and in respect of the prevailing partial pressure of water vapour present in the gases, by means of a coolant, suitably water, located on the other side of the heat-exchanger walls. The partial pressure of the water vapour in the gases can be increased by applying,one of the following steps: supplying water or hydrogen-containing compounds to the combustion process, adding water or hydrogen-containing compounds to the gases, or cooling the gases at elevated pressures.

Abstract: ABSTRACT The recovery of oil or gas from underground porous formations bearing such hydrocarbons is enhanced by using an injection fluid containing a viscosifying amount of a poly(vinylamine) formed in-situ by hydrolysis of a high molecular weight poly(N-vinylamide).  The hydrolysis conditions are strongly acidic or highly alkaline and include the elevated temperature of the formation. The poly(N-vinylamide), such as poly(N-vinylformamide), can be made by inverse emulsion polymerization and the high solids emulsion mixed directly with the acidic or basic solutions to form the injection fluid.   The process is applicable to enhanced oil recovery using fluids for water-flooding, well completion or workover, and acidifying or fracturing.
