Abstract:
A bimetallic spacer for supporting fuel rods in position in a nuclear reactor fuel assembly substantially comprises inner and outer structural elements of a first metallic material and spring elements of a second metallic material. The structural and spring elements together define a lattice, the interstices of which receive the individual fuel rods. The structural elements and spring elements in the spacer are connected together by forming the structural elements with openings and fitting the ends of the spring elements in the openings. At one end of the opening in the structural element, two slots can be provided for forming a tongue-shaped member which is moved aside to make space for the spring element and then moves back when the end of the spring element is in position, thus preventing a possible vertical return movement of the end of the spring element.
Abstract:
Nuclear fuel assembly having four bundles of fuel rods, at least one fuel bundle being made with twenty symmetrically arranged fuel rod positions, the number of fuel rod positions in each of the remaining fuel rod bundles being at least sixteen and at most twenty-five.
Abstract:
In a method for improved turbo decoding in a wireless communication system, jointly allocating (S10) a predetermined maximum number of decoding iterations to a batch of received decoding jobs; and consecutively performing decoding iterations (S20) adaptively for each job in the batch until a convergence criteria is reached for each job in the batch, or until the predetermined maximum number of iterations for the batch is reached.

Abstract:
Automatically adjust the size of a Physical Uplink Control Channel, PUCCH, of an uplink communication subframe. In a particular embodiment, the size of a semi-static region of the PUCCH is adjusted. The adjustment is based on a utilization factor of the PUCCH over a time period. The adjustment can also be based on the connection factor (connections between the wireless terminals and the cell) and/or based on the utilization factor of a PUSCH (Physical Uplink Shared Channel). The result is an efficient resource utilization on the PUCCH, and a properly dimensioned PUCCH region.
Abstract:
A method for the acceleration of an electromagnetic rapper, particularly for an electrostatic precipitator, which includes a metal cylinder as a hammer, an electrical coil for lifting the metal cylinder and a coil energizer for energizing the electrical coil. For cleaning a surface the metal cylinder is lifted by an initial electrical pulse generated by the coil energizer. The coil energizer supplies the electrical coil with an additional electrical pulse so that the metal cylinder is accelerated when it has reached the maximum point of its trajectory.
Abstract:
A unit is provided for holding instruments and components that are used in dental treatment. The unit can comprise sides, a bottom, and a top that can be modular or integrally formed. The unit can have a drawer-shaped construction and can be made of heat-resistant material. The sides and bottom can form a first rigid unit part, all or part of which can be provided externally with a covering or layer of a non-rigid or flexible material. The covering or layer is arranged to be easy to hold and to have good frictional characteristics. The top can form a rigid second unit part that preferably contains an organized holding arrangement for the instruments and components. Accordingly, the unit can be heat-resistant, robust and easy to hold, and have good frictional characteristics to prevent it sliding on an underlying surface upon which the unit is arranged placed.

Abstract:
Device for measuring physical properties of the tympanic membrane (TM), comprising an elongated probe (12) with a distal end (15) for inspection of the ear, wherein a plurality of optical fibres is arranged in said elongated probe. The plurality of fibres includes either a first set of fibres (21) for conveying light from a light source to said distal end of said probe and a second set of fibres (22) for conveying light reflected from the tympanic membrane in front of said distal end to a first detector means (23) or a set of fibres both for conveying light from a light source to said distal end of said probe and for conveying light reflected from the tympanic membrane in front of said distal end to a first detector means (23). Said first detector means (23) is designed for measuring the intensity of light reflected from the tympanic membrane. Method for measuring physical properties of the tympanic membrane (TM), including the following steps: a) illuminating the tympanic membrane with light from a light source, b) detecting light reflected from the tympanic membrane, and c) analysing the intensity at selected wavelengths or a spectrum of wavelengths.
