Abstract: It is presented an inverter type motor drive device for feeding three phase AC electric power to an electric motor, the inverter type motor drive device comprising: an insulated metal substrate board on which, for each of the three phases, a plurality of power switches are mounted in straight lines in switch assemblies along a first direction; a printed circuit board on which a plurality of capacitors are mounted; and two DC power input terminals. The inverter type motor drive device further comprises three AC power output terminals, each extending through the printed circuit board while avoiding galvanic contact with the printed circuit board, and each of the three AC power output terminals comprise an elongated AC busbar, wherein a longitudinal direction of the AC busbar extends along the first direction.

Abstract: It is presented an inverter type motor drive device for feeding three phase AC electric power to an electric motor, the inverter type motor drive device comprising: an insulated metal substrate board on which, for each of the three phases, a plurality of power switches are mounted in straight lines in switch assemblies along a first direction, wherein two switch assemblies are assigned for each phase; a printed circuit board on which a plurality of capacitors are mounted, wherein the printed circuit board is essentially parallel to the insulated metal substrate board; and two DC power input terminals mounted on the printed circuit board.

Abstract: A wheel supporting system for vehicles in which the wheel (1) is supported by a fork (10) with at least one bracket (10a, 10b), on which the wheel (1) is journalled rotatable round a horizontal axle. The fork (10) is turnable round a vertical axle and controllable by a turning mechanism (17). The turning mechanism with shock-absorbers (5, 19, 23-26) is vertically movable and fixed to a bracket (3, 32) which is vertically adjustable by means of shifting mechanisms (6, 20.22, 28-31), in relation to a support (4, 35) fixed to the chassis.

Abstract: A vehicle wheel with inflatable tyres, mounted on the same rim. One of the tyres (1), called a summer tyre, has tread suitable for summer use and at least one additional tyre (10), called a winter tyre, with a tread suitable for winter use. The winter tyre (or tyres) is mounted on the side of the summer tyre and is, in summer conditions, not fully inflated and hence not in contact with the road surface, because its circumference in its semi-inflated state has a shorter radius than that of the circumference of the summer tyre. The winter tyre (10) is securely attached to the outer surface of a concentric volume accumulator (7), which is part of the wheel rim and functions as a constantly available spare tyre. When inflated, the winter tyre (10) can expand, so that it has the same outer radius as the summer tyre (1) and thus also comes into contact with the road surface.

Abstract: A method of combusting a fuel, and a combustion plant are proposed. The combustion plant comprises a first circuit (1) with a gasifying reactor (3) to produce a combustible gas and a degassed, combustible rest product from the fuel. The combustible gas is supplied to a first combustion chamber (6) and there it is combusted while forming combustion gases. First means (8, 9) are arranged to take advantage of the energy in these gases. The plant further comprises a second circuit (2) with a second combustion chamber (15) which is supplied with the combustible rest product from the gasifying reactor (3). The rest product is combusted in the second combustion chamber (15) while forming combustion gases. The second circuit (2) further comprises second means (23, 24) for taking advantage of the energy of the combustion gases produced in the second circuit (2).

Abstract: Connection arrangement for pressure medium ducts in a diesel engine for connecting at least two ducts (2,3), included in the same pressure medium system, located parallel in the longitudinal direction of an engine block (1) and being in successive order in the flow direction of the pressure medium circulation of the system, either together or separately with one or more devices or units, for instance with coolers (8,9), located on the side of the ducts and included in the pressure medium system in question so that a desired direction of flow is accomplished and that said connection prevents the pressure medium flow of the inlet side and of the outlet side of the device from being mixed with each other. The arrangement includes a set of different, preferably cylindrical, hollow duct assemblies (4) to be installed in a connection chamber made in the engine block at a desired location.

Abstract: A vibratory cleaning apparatus applies ultrasonic energy to component parts or workpieces directly resting on a vibrator surface. The surface forms part of a conveying arrangement that moves the parts as they are cleaned. Conveyance of the parts during their vibratory cleaning provides control of the time of cleaning. In various embodiments, the conveying arrangement can be an inclined plate or surface which is the vibration imparting member, an endless conveyor through which vibrations are conducted, or a wiper driven across a vibratory plate to move the workpieces thereon. The cleaning apparatus is suitable for large scale cleaning of production line parts or individual work bench application. In preferred embodiments, a further conveying arrangement automatically delivers the parts from the bath in which the ultrasonic transducer is located.
