Abstract: A surface of a workpiece is treated by rotating about an axis a brush having a multiplicity of radially projecting bristles with tips engaging a surface of a workpiece to be treated while positioning a stop nonrotatable with the brush in engagement with the bristles radially inward of the stop so as to rearwardly deflect the bristles prior to contact with the workpiece and thereby store kinetic energy in the bristles so that as the bristles pass the stop the kinetic energy is released and the bristles spring elastically forward and percussively strike the workpiece surface. A roughness of the workpiece surface is determined and the stop is positioned radially relative to the axis or the brush is positioned relative to the workpiece at a spacing in accordance with the determined roughness.

Abstract: A method is for filling a fillable portion of a garment to be padded to obtain a padded garment, such as a garment or blanket. A cashmere fiber mass is fed towards a carding station. The cashmere fiber mass is mechanically opened and blended in the carding station by a carding machine to obtain a staple cashmere fiber. The staple cashmere fiber exiting from the carding station is fed towards a beating station. The staple cashmere fiber is cleaned in the beating station by cleaning air flow adapted to cross and inflate the staple cashmere fiber to remove residual impurities and dust from the staple cashmere fiber. The staple cashmere fiber exiting from the beating station is fed towards an injecting station and injected into the fillable portion by a pusher for introducing the staple cashmere fiber into the fillable portion to obtain the padded garment.

Abstract: The subject of the present invention is a rotationally drivable rotary tool device and in particular a rotary brush tool. The invention is equipped, in its basic construction, with a tool holder (1, 2) having at least one drive-side clamping element (1) and a tool-side clamping element (2). The two clamping elements (1, 2) are connected releasably together and receive a rotary tool (5, 6). Furthermore, the two clamping elements (1, 2) ensure that the rotary tool (5, 6) is held. According to the invention, the tool-side clamping element (2) and the rotary tool (5, 6) define a structural unit (2, 5, 6). To this end, the clamping element (2) in question is configured as a holding cage (2) that encloses the rotary tool (5, 6) radially and axially at least in part.

Abstract: The present invention relates to a brush unit (3) and to an associated rotary brush tool. The brush unit (3) is equipped with a brush holder (10, 11), which can be driven in rotation, and with an annular brush (4, 5) with a bristle-covered rim (8) with outwardly protruding bristles (5). Furthermore, a stop means (14) which dips into the rotating bristle-covered rim (8) is provided. According to the invention, the stop means (14) simultaneously acts as an abrasive body (14) for the bristles (5). In this case, a distinction is made between both functions (stopper function and abrasive function) according to a direction of rotation (R) of the annular brush (4, 5) and/or a setting position of the stop means (14) as compared to the bristle-covered rim (8).

Abstract: A power-brush apparatus has a housing and a brush rotatable on the housing about a brush axis and having bristles extending generally radially of the axis and having tips defining on rotation of the brush a circular orbit centered on the axis. The tips are engageable at a location with a workpiece surface. In accordance with the invention a blocking element is positioned radially inside the orbit immediately upstream from the location in a normal rotation direction of the brush. A drive rotates the brush in a working direction about the axis relative to the housing at a predetermined angular speed in the direction and thereby orbits the tips of the bristles about the axis such that the bristles engage the blocking element, are slowed thereby, and when released thereby snap back to accelerate forward and strike the workpiece at an augmented speed.

According to the invention, coolant for the cooling thereof is supplied to the brush holder (3) and/or the annular brush (4).

Abstract: An obstetric vacuum extractor (20) comprises a cylinder (22) communicating with a cup (26), and a handle (46) connected to a piston (38) via an extensible bias element (52) to evacuate the cup. The bias element permits relative movement between the handle and the piston. The bias element limits force transmitted to the piston, and movement of the piston relative to the handle operates an indicator to confirm that low pressure has been maintained within the cup. A cup for such an extractor comprises inner (130) and outer (132) sections, at least the outer section being reconfigurable, by applying distal force to a proximal side of the cup, from a convex insertion state for insertion into a mother's birth canal into a concave engagement state for engagement with a baby's head. A boundary between the sections is shaped such that the inner section may be concave while the outer section is convex, to create an inner suction cup.

Abstract: A power-brush apparatus has a housing, a brush rotatable on the housing about a brush axis and having bristles extending generally radially of the axis, and a drive that rotates the brush in a working direction about the axis and thereby orbits tips of the bristles about the axis. Thus when in use the brush is rotated in this working direction. A support immediately adjacent the housing carries a rigid grinding wheel having an abrasive outer surface. This wheel is biased radially against the bristle tips to sharpen and clean them while a drive relatively displaces the bristle tips and the grinding-wheel surface while the wheel is urged against the bristle tips such that the grinding wheel surface primarily engages rear sides of the bristle tips turned away from the working direction.
