Abstract: A stirring device to be used for stirring a semi-solid metal slurry, wherein the stirring device is to rotate around a rotational axis (X-X) when used for stirring a semisolid metal slurry. The stirring device includes an elongated shaft extending along the rotational axis (X-X), and at least two wings securely arranged to the elongated shaft and extending radially outwards from the elongated shaft, wherein the at least two wings also have a substantial axial extension along the rotational axis (X-X). Hereby, whirls are produced in the slurry that results in a well-homogenized slurry with no large metal oxide surfaces inside. Disclosed is also a production method and a system for producing the slurry.

Abstract: The present invention relates to an arrangement for aligning a sub-calibre barrel (1) for use in a principal weapon barrel comprising i) an insert (4) arranged in said principal weapon barrel ii) front securing means (8) for aligning the sub-calibre barrel (1) iii) rear securing means for securing the rear end of the sub-calibre barrel (1), wherein iii.a) said rear securing means comprise a barrel nut (2) in which said sub-calibre barrel (1) is inserted; iii.b) clamping means (3a, 3b) securing said barrel nut (2) to said insert (4) and said clamping means (3a, 3b) in said principal weapon barrel. The invention also relates to a training weapon comprising the arrangement and a method of aligning the training weapon.

Abstract: Welding apparatus (10; 30) having a safety feature comprising: two electrodes (11, 12; 21, 22), whereof at least one of said two electrodes is movably arranged in relation to the other electrode. The electrodes are in non-contact with each other and define a gap (13) in which an object (14) provided with an electrically non-conductive surface to be sealed may be inserted. The welding apparatus comprises an actuator (15; 25) configured to move at least one electrode when activated to squeeze the object, a detector (16; 26) configured to determine a clamping force when the inserted object (14) is squeezed between the electrodes, a distance sensor (17; 23) configured to measure the distance between the electrodes. There is also a conductance sensor (24) configured to measure the conductivity of an object located between the electrodes (11, 12; 21,22) when the object (14) is squeezed, and optionally a position sensor (19b) configured to detect the position of the object (14) inserted between the electrodes.

Abstract: This disclosure relates to a cordless, hand held and electrically powered apparatus, comprising a welding unit (12), a power unit (4) for powering the welding unit, wherein the power unit is connectable directly to and disconnectable from the welding unit via an interface. The power unit is provided with a push button (16) that is configured to energize the welding unit when pressed down, thus initiating operation thereof. The advantage is that the apparatus can be made more compact, and thereby ease of handling is improved. Preferably, the welding unit and the power unit each comprise circuitry (17a, 17b) configured to exchange information when mounted together via the interface. The information is usable for a determination whether the power unit is a correct one or not.

Abstract: A blood mixer comprises a support structure supporting the components of the mixer (10), a tubing fastening and guiding arrangement, configured to secure a blood collecting tubing in the mixer (10), a tray (18) adapted to house a blood collecting bag (16) having a blood tube (14) attached thereto, and configured to measure the weight of the collected blood in the blood collecting bag (16) and a pump (20) configured to draw blood from the donor (12) to a blood collecting bag (16) through said tubing (14). The pump (20) is configured to exert a kneading action on the blood supply tubing (14) by means of at least two kneading elements arranged to alternatingly displace the contents of the tube in the direction towards the bag (16). There is also provided a cooling arrangement (19) configured to cool the blood in the blood collecting bag (16).
