Abstract: A method for condensation of gaseous hydrocarbons from a mixture of inert gas and gaseous hydrocarbons, particularly as found in storage tanks of an LPG/LEG ship. According to the method, the condensate and the cargo gas composition are heat exchanged with a part of its condensate, and with a cargo gas/inert gas mixture, which is to be released to the atmosphere or burned, in a separate condensation step.

Abstract: In the production of ferrosilicon in an electric reduction furnace by the reaction of iron-containing, silica-containing and carbonaceous materials, agglomerates containing a substantially homogeneous mixture of iron or a reducible iron compound and a carbonaceous material are used to replace at least a portion of the iron-containing materials in the furnace. These agglomerates have a weight ratio of carbon to iron of 0.2:1 to 1.5:1 in their reduced form after reaction in the furnace.

Abstract: The present invention provides a method of linking a target particle to an insoluble support, wherein said particle is bound support by means of a specific binding partner, characterized in that the linkage between said binding partner and said support comprises hydroxyboryl/cis-diol bond.

Abstract: Pressure gauge for very high pressures based upon a principle similar to the Bourdon tube, comprising a beam-shaped measuring element having an elongate cavity lying eccentrically in the cross section of the measuring element, and being supported by a holder member at one end. The measuring element is composed of two substantially plate-shaped parts manufactured in planar technology, preferably of silicium or quartz. One plate part is provided with an elongate recess in that surface which faces against a cooperating surface on the other plate part, so as to form the eccentric cavity. Both plate parts are jointed at the surfaces in such a manner that the cavity is sealingly closed. The measuring element is adapted to be subjected exteriorly to the very high pressures to be measured.

Abstract: The present invention relates to a binary assay method capable of providing wide dynamic range, a high degree of precision and rapid processing times in which analyte is reacted successively with two independently determinable forms of solid-supported binding partner and also with a labelled ligand having affinity for the analyte or binding partner. The analyte concentration is determined from signals deriving from the resulting two forms of analyte-binding partner-labelled ligand systems by reference to a double standard calibration curve. A kit for use in the method is also disclosed.

Abstract: Process for producing a dispersion, wherein dispersed slightly crosslinked polyvinyl seed particles are swollen with an ionizing liquid, said seed particles containing covalently linked ionizable groups causing a swelling of the seed particles by the ionizing liquid to form a dispersion of droplets, wherein the resulting droplets after the swelling have a volume which is at least five times that of the seed particles. Said ionizing liquid may be or contain a polymerizable monomer or be charged with such a monomer. Polymerization of the monomers is effected in the droplets during or after the swelling, to form polymer particles.

Abstract: A vapor compression system includes a compressor, a heat rejecting heat exchanger, an expansion device and an evaporator connected in series to form a closed circuit operating at supercritical pressure in a high pressure side of the circuit. A large part of the internal volume of the circuit is incorporated at or close to a refrigerant outlet from the heat exchanger. The actual refrigerant charge corresponds to an optimum overall density ensuring self-adaptation of the supercritical high-side pressure to maintain maximum energy efficiency at varying heat rejection temperatures of the heat exchanger.

Abstract: A method for active noise reduction based on destructive interference of sound waves in order to reduce the energy in a sound field employs two omnidirectional microphones (M1, M2) provided in connection with a loudspeaker. The acoustic feedback of the microphones is eliminated by a closed loop consisting of the microphones and the loudspeaker. The loudspeaker used is an open loudspeaker with a dipole characteristic, thus causing one of the microphones to be more sensitive to the far field and thereby to the noise which has to be suppressed. The method is implemented by a device which comprises a digital signal processor (DSP) for processing the microphone signals and which transmits an output signal to the loudspeaker where the feedback component from the loudspeaker is substantially eliminated, while the output signal's phase and amplitude are adjusted in such a manner that an effective cancellation of the noise is obtained in an area around the loudspeaker's near field.

A movable partition defines at least one side of the compartment and is displaceable between first and second positions respectively defining first and second volumes of refrigerant within the compartment.

Abstract: The invention provides a plant for the storage of fish and shellfish that includes a net cage for submerging in a body of water. The cage includes a floor section, surrounding walls with bottom ends thereof attached to a perimeter of the floor section, and an upper roof section of netting with bottom ends thereof attached to top ends of the walls. The roof conforms to a frustoconical shape when in use and includes a central buoyant member in an upper end thereof.

The individual stages of the gear machine each include a pair of meshing gears, preferably cylindrical spur gears of equal diameter and diminishing width from stage-to-stage.

Abstract: High side pressure in a transcritical vapor compression cycle system is regulated by varying a liquid inventory of a low pressure refrigerant receiver provided in a circuit of the system. The circuit includes a compressor, a gas cooler, a throttling valve, an evaporator and the receiver connected in series in a closed circuit operating at supercritical pressure in a high pressure side of the circuit. The degree of opening of the throttling valve is controlled to regulate the high side pressure in the circuit. It is possible to control capacity, and it also is possible to achieve minimum energy consumption for a given capacity requirement by regulating high side pressure.
