Abstract: The invention relates to an impact machine which is adapted to perform a hammering operation on a surface or an object to be worked upon. In particular, a vibration reduction arrangement is attached to the housing and comprises a moveable counterweight, interacting with a motion reversing arrangement having a non-linear spring characteristics, such that the motion of the counterweight can be brought into a counter-acting movement in relation to the vibrations in the housing of the hammering element thus substantially reducing the vibrations. A spring action arrangement is arranged inside said counter weight, the counter weight being movable a first distance without actuating the spring action arrangement, and the counterweight comprises displaceable projecting member for actuating the spring action arrangement.

Abstract: The invention relates to an impact machine (100, 200) which is adapted to perform a hammering operation on a surface or an object to be worked upon. In particular, a vibration reduction arrangement (140, 240) is attached to the housing (105, 205, 305, 405) and comprises a movable counterweight, interacting with a motion reversing arrangement having a non-linear spring characteristics, such that the motion of the counterweight can be brought into a counter-acting movement in relation to the vibrations in the housing (105, 205, 305, 405) of the hammering element (110, 210, 310, 410) thus substantially reducing the vibrations.

Abstract: A ventilator for supplying breathable gas to a patient includes an external housing; an internal housing suspended within; a gas flow generator within said internal housing; a gas inlet conduit extending between a first gas inlet opening in said external housing and a second gas inlet opening in said internal housing, and a gas outlet conduit extending from a first gas outlet opening in the internal housing via a second gas outlet opening in the external housing and to a patient interface means adapted for introducing the breathable gas into the airway of said patient. One or both of the gas inlet and outlet conduits exhibit a first substantially rigid conduit section and a second membrane conduit section with a membrane wall portion separating a volume of breathable gas within the gas inlet conduit and/or gas outlet conduit from a volume of ambient air within the external housing.

Abstract: The invention relates to a wheel-mounted lawnmower (1) or the like of the type comprising a cutting device (2) which is connected to a motor (3) for performing a cutting function, the lawnmower (1) being operated by an operating means (4). The lawnmower (1) has a first unit (5) which is provided with said cutting device (2) and said motor (3), a second unit (6) which has at least two rotatable wheels (7) for moving the lawnmower relative to a base, a wheel frame (8) for arranging the wheels and for arranging said operating means (4) on said wheel frame (8), and an insulator (9) which is arranged to at least partially mutually connect said first (5) and second (6) unit to reduce any vibrations between said units (5, 6). The invention also relates to an insulator arranged on a lawnmower or the like. The invention also concerns us eof a lawnmower or the like as stated above.

Abstract: A balancing method and apparatus is used for dynamically balancing an out of balance condition in a rotating body caused by resistance forces acting tangentially to the body. A device having a rotatable component and automatic or dynamic balancing includes a housing, a shaft rotatably mounted in the housing, the shaft supporting the component near one end of the shaft, at least one counterweight fixedly mounted on the shaft and at least one automatically adjusting balancer mounted on the shaft. The automatically adjusting balancer includes one or more compensating masses contained to move about a path relative to the shaft to compensate for variable imbalanced forces acting on the component.
