摘要： A device for the separation of solid objects (9) from fluid flowing in a conduit tube (2) includes a housing that includes a tubular outer wall (3) and a tubular inner wall (4). Between these is delimited a collecting space (8). Concentrically relative to the inner wall (4) is provided a rotation-symmetrical central body (12) which at opposing ends cooperates with flow converting devices (15, 16), which transform incoming flow to a rotative motion and outgoing flow to an axial motion. In the inner wall (4) are recessed tangentially separated holes (20) of elongated shape, through which the scrap objects may pass and be collected in a collecting space (8). In the collecting space (8) a calm flow operation is obtained which guarantees that collected scrap objects are not carried away and returned to the main fluid flow through the separation device.

摘要： A device for mixing two fluids having different temperatures comprises a connecting branch (6) extending into a main pipe (1) from a secondary pipe (2), said connecting branch having at its end positioned in the main pipe a distribution casing (7) with double annular walls, of which an inner wall (9) defines a channel (10) extending axially and centrally in the main pipe (1), and having apertures which allow a fluid (B) to be conducted into and mixed with the fluid (A) passing through the main pipe. The apertures consist of a plurality of small apertures (11) which are formed in the inner wall (9) of the distribution casing (7) and provide intermixing of the two fluids directly in the channel (10) positioned centrally in the main pipe (1).

摘要： The invention relates to an arrangement for material transport and/or energy transport by means of electric arc. Measured values are transferred with suppression of disturbances from the HF device (2) without appreciable damping of the HF voltage to the electrode (14). A measurement winding (16) is arranged together with a power winding (8) in such a way that effective suppression of disturbances is achieved. Examples of areas of application are thermal spraying, cutting and welding, in particular mechanized TIG welding, but the invention is principally indicated in cases where a spark is established with HF voltage across a gap filled with a gas or a gas/liquid mixture and where at the same time some parameter has to be measured in connection with the spark gap.

摘要： The invention relates to a process for the production of a milling tool for cutting machining, preferably of metals. The milling tool includes a holder part (2) for the fixation of the milling tool upon a rotating driving arrangement, and an insert carrying part which around its periphery is equipped with several detachable cutting inserts (23), each cutting insert being fastened in an insert seat, which at least partly is situated in a peripheral, insert-carrying milling tool portio (12). Each insert seat includes a bottom support surface (10) and a side support including at least one side support surface (9), a chip pocket (25) being provided in front of each insert seat in the direction of rotation. The side support of the insert seat at least partly is made by a ball-nose end mill (8). This brings about that the number of insert seats in a milling tool may be substantially increased.

摘要： The invention relates to an arrangement for contact arc ignition in manual TIG welding and to a method for welding with this arrangement. The arc is established by lifting the welding torch (12) after contact between electrode (13) and workpiece (14) under low ignition current. When the arc length is sufficient, the welder orders a change-over to welding current via an operating device (11). The invention can also be used for controlling the supply of heat to the workpiece both during continuous bead application and during the crater filling time at the end of welding. The invention creates reliable ignitions without extensive use of control electronics, and it substantially reduces the electrode wear in manual TIG welding.

摘要： A unit for treating liquid comprises a cylindrical container (1) which, in an upper chamber (6), has a set of slender tubes (8) which the liquid is forced to pass on its way from an inlet (10) to an outlet (9), so as to be subjected to a treatment, such as deionization, during this forced passage. An annular casing (11) is arranged in a lower chamber (7) and serves to distribute the liquid flowing in through the inlet (10). The casing (11) is defined by inner and outer side walls (12, 13) sealingly interconnected along an upper edge portion (14) as well as interconnected by at least one lower, transverse wall (15) which is provided with a plurality of small holes through which the liquid is squeezed out in the form of a large number of individual jets. The cross-sectional area of the liquid-distributing casing (11) continuously decreases away from the inlet (10) towards an opposite end (18) of the casing. A centrally located means (9) is arranged in the free chamber (7) of the container for deflecting and guiding the liquid flowing inwards from the annular casing (11), in a controlled and even, upwardly-directed flow.

摘要： An inverter provides alternating current (iout) to a load (130) containing a welding circuit. The inverter includes at least one commutation circuit (110) and a bridge circuit (120) connected to a bus forwarding power from a DC power source (100). The bus is also galvanically connected to the load (130) via the bridge circuit (120). The at least one commutation circuit (110) receives power from the DC power source (100); receives energy from inductive elements in the load (130) during a storage phase of a cyclic procedure, and controls energy feedback to the load (130) during a feedback phase of the cyclic procedure. The at least one commutation circuit (110) is a two-pole having a first pole (p1) connected to a first node (A) and a second pole (p2) connected to a second node (B). The at least one commutation circuit (110) is arranged to receive energy from the load (130) and feedback energy to the load (130) via the first and second nodes (A; B), either directly or via the bridge circuit (120). Energy-flow control means (DIN, SOUT) in each of the at least one commutation circuit (110) control energy to be stored in and taken out from a recovery capacitor (CR) in the commutation circuit (110) in question. The bridge circuit (120) delivers the alternating current (iout) to the load (130).
