Granted: 2005-07-04
Abstract: A movable safety valve (11) connected to a fixed safety valve (10) via a telescopic casing (9) is mounted in a closed position around the drill pipe arrangement (20), the fixed valve is then opened and the movable valve is moved downwards to retract the casing while the drill pipe arrangement is held by this valve and then the fixed valve is closed and the movable valve is opened and moved upwards to extend the casing while the drill pipe arrangement is held by the fixed valve. Constructing a drill pipe arrangement which is located in a pressurized borehole and movable by a safety valve having a fixed position relative to the borehole comprises: (a) mounting a safety valve which is movable relative to the borehole in a closed position around the drill pipe arrangement and at a distance above the fixed valve, using a telescopic casing around the arrangement to connect the two valves; (b) opening the fixed valve; (c) moving the movable valve in a downwards direction so that the telescopic casing becomes retracted while the drill pipe arrangement is held by this valve; (d) closing the fixed valve; (e) opening the movable valve; and (f) moving the movable valve in an upwards direction so that the telescopic casing becomes extended while the drill pipe arrangement is held by the fixed valve. Independent claims are also included for the following: (a) dismantling the same drill pipe arrangement, comprising the same steps as above except that in step (c) the movable valve is moved in an upwards direction so that the casing becomes extended while the drill pipe arrangement is fixed to the movable valve and in step (f) the movable valve is moved in a downwards direction so that the casing becomes retracted whilst the drill pipe arrangement is held by the fixed valve; and (b) an apparatus (1) for carrying out both of these methods, in which the casing is in sealed contact with the fixed valve.

Abstract: In splicing two optical fibers to each other using an electric arc formed between electrodes images of the regions being heated and thereby fusioned to each other are taken. The images cover a rectangular field (43) having the fibers located centrally, along a center line of the field and parallel to the long sides of the field. The images are evaluated to determine a value of the position of the center of the electric arc in relation to the position of the end surfaces of the fibers. This value can then be used for placing the end surfaces just at the arc center. In the image the image of the optical fibers can be excluded so that only light intensity from the air discharge of the electric arc is recorded in the captured images. The field (41) excluded can be a narrow strip of uniform width located symmetrically around the image of the fibers. Using such a repositioning of the end surfaces of the fibers results in splices which are substantially equal to each other and thus a well repeatable splicing process is obtained.

Abstract: An interface arrangement is disclosed for ensuring proper dosing as well as achieving a safe operation and handling of a dry powder inhaler (DPI) used for administration of a powder to be inhaled. The interface of the present invention primarily handles the loading of a cassette (4) carrying pre-metered doses into the dry powder inhaler (8). An important characteristic is that the interface by utilizing a particular coding prevents a user from loading a cassette not containing the proper powder. Additionally the interface informs a user when a new mouthpiece has to be replaced after being used for a pre-defined number of inhalation operations. Additionally the interface informs a user when a present cassette has delivered its last dose and should be exchanged. Also information on the number of further cassettes already utilized will control that another cassette still is permitted to be loaded. If this counter exceeds a pre-defined number of used cassettes the inhaler then is by definition worn out, whereby the present dry powder inhaler has to be scrapped. In that case the last cassette will not be able to be released from the inhaler device but will accompany the inhaler when it is discarded.

Abstract: A method of and apparatus for compensating a received signal's phase compensates for the distortion caused by the asymmetrical characteristics of a voltage limiter. This compensation allows the received signal to be sampled at the positive and negative zero-crossings reducing the requirements of a local oscillator in a radiotelephone system. First, the phase of the received signal is sampled at the positive and negative zero-crossings, forming a corresponding positive-crossing and a negative-crossing phase value for the received signal. Second, the negative-crossing and positive-crossing phase values are combined, forming a first difference signal. Third, an estimated error signal is formed using the first difference signal. Fourth, the estimated error signal is combined with the positive or negative zero-crossing phase signals, substantially eliminating the asymmetrical distortion.

Abstract: A method for treating raw milk to produce treated milk having a lower bacterial content than the raw milk. The milk is homogenized and, within about 5 minutes from the homogenization, subjected to dynamic microfiltration, to yield a filtrate which has a lower bacterial content than the initial raw milk. When the flow rate of milk through the microfilter drops below a predetermined level, the dynamic microfilter is removed from milk filtration service, flushed with water, and returned to milk filtration service, the steps being repeated as necessary until the membrane cannot be rejuvenated to a minimum filtration capacity, at which time the membrane is subjected to chemical cleaning to essentially restore the original filtration capacity of the membrane.

Abstract: The invention regards a recuperative heat exchanger for the exchange of heat between two media across a heat transferring wall. According to the invention the heat transferring wall is made from a shaped patterned sheet which is folded repeatedly to form a multi-layered package (12) which is enclosed in a casing (15, 21), so that the sheet, owing to its configuration, after folding forms a package of alternating flow channels with connecting ports (22-25) for the two media at two opposite sides of the sheet package, said sheet being sealed against the casing at the bottom and the top of the package and at the two ends of the package so that leakage between the two media is prevented. The invention also relates to a method of producing such a heat exchanger.
