Abstract: A manually guided apparatus for collecting objects, especially fruits and nuts, including a pick-up drum rotatably mounted in the drum chamber of a housing. The drum is disposed approximately transverse to the direction of operation, and is rotationally driven by a drive unit. The housing has a wall section extending over the width of the drum approximately at the level of the outer diameter thereof. A ground support is disposed in the region of ends of the drum. A collection channel provides communication for picked-up objects between the drum chamber and a collection receptacle for receiving the objects. The wall section of the housing and the drum cooperate with one another such that objects are accelerated along the wall section toward the collection channel and are ejected out of the drum chamber along a trajectory into the collection receptacle. A handle is operatively connected to the housing for moving the housing in the direction of operation.

Abstract: A vacuum arrangement has a vacuum pipe having a vacuum opening facing a ground surface and adapted to pick up from the ground surface a material to be collected. The vacuum pipe conveys the material to be collected into a collecting container connected to the vacuum pipe. The vacuum pipe has a working area located within the area of the vacuum opening. At least one blower nozzle having a blower air exit is arranged such that a blower air flow exiting from the blower air exit is directed onto the ground surface into the working area. The blower air exit and the vacuum opening are positioned at a spacing relative to one another.

Abstract: A muffler assembly for an internal combustion engine of a portable handheld work apparatus such as a motor-driven chain saw, cutoff machine or the like includes an exhaust-gas muffler (1) which has a muffler housing (10). The muffler housing (10) is formed essentially from two half shells (24, 25) connected substantially fluid-tight to each other. The interior space of the muffler housing (10) includes at least two chambers (2, 3) which are partitioned from each other by a partition wall (4). A catalytic converter (5) is mounted in the partition wall (4). In the interior space of the muffler housing (10), an exhaust-gas inlet (6) opens which is connected to an exhaust-gas stub (9) of the cylinder (8) of the engine. The exhaust-gas muffler has an exhaust-gas outlet (7) which conducts exhaust gas from the interior space.

Abstract: A fan arrangement of a portable handheld work apparatus is driven by an internal combustion engine and includes a radial fan (1) which includes a fan wheel (5) and a spirally-shaped fan housing (6) which encloses the fan wheel (5) at least partially. A take-out opening (3) is provided in the radial fan (1) in the region of the moved air flow (2) for diverting a combustion air flow (4) for the engine. The combustion air flow (4) is branched off from the air flow (2). In the radial direction outside of the fan wheel (5), there is an aerodynamically formed guide ramp (7) provided in the air flow (2) which rises in the axial direction. The take-out opening (3) is arranged downstream of the guide ramp (7).

Abstract: An intake system for preparing combustion air (1) is for an internal combustion engine of a portable handheld work apparatus. The intake system includes: a carburetor (2); an air filter (3) which is connected upstream of the carburetor (2); and, a filter case (4) which closes the air filter (3) from the outside.

Abstract: An exhaust gas muffler is provided for an internal combustion engine, especially for an internal combustion engine in a manually-guided implement such as a power saw, a cut-off machine, or the like. The muffler has a housing having an inlet for exhaust gases and an outlet out of the housing. To achieve an after burning of exhaust gas in a straightforward manner, the exhaust gases in the housing flow through a reaction zone in which the exhaust gases circulate at least partially.

Abstract: An exhaust gas muffler is provided for an internal combustion engine, especially the engine of a manually-guided implement such as a power saw, a cut-off machine, or the like. The muffler has a housing having an inlet for exhaust gases and an outlet out of the housing. The housing has an outer wall over which the exhaust gases from the outlet flow. To achieve an adequate cooling of the exhaust gas muffler and the discharging exhaust gases, the exhaust gases out of the outlet draw in atmospheric air between the exhaust gases and the outer wall of the housing.

Abstract: A device to store a mobile telephone having a base with a post extending therefrom and an adjustable telephone support having the form of a medical patient positioning device being attached to the post.
