Abstract: A modular handle assembly includes a dial rotatably connected to a handle and rotatable about a first rotary axis. A first gear arm extends from the dial and terminates at a first traction surface. A second gear arm is connected to the handle and rotatable about a second rotary axis that is parallel to the first rotary axis. The second gear arm terminates at a second gear tip that presents a second traction surface disposed against the first traction surface such that rotation of the dial in a first rotary direction effectuates rotation of the second gear arm in an opposite direction. A cam is coupled with at least one of the first and second gear tips and presents at least one deflection surface for deflecting a deflection wire during rotation of the dial to steer a distal end of a steerable catheter containing the deflection wire.

Abstract: An actuable shaft assembly for a spray mop assembly includes first and second hollow elongated outer shaft segments in which first and second elongated actuating rod segments are telescopingly disposed, respectively. The first and second outer shaft segments include respective first and second shaft retaining elements extending into their hollow interiors. The first and second rod segments include respective first and second rod retaining elements extending radially outward from their outer peripheral surfaces. The rod retaining elements and shaft retaining elements are sized and disposed to limit telescoping movement of the associated rod segments outward from the shaft segment ends.

Abstract: A sealing arrangement includes a stationary spindle and a wheel hub rotatably mounted to the spindle. A seal assembly is disposed between the spindle and the wheel hub and includes an outer carrier case having a first cylindrical portion disposed in the inner bore of the wheel hub and a first radial portion extending radially inward from an end of the first cylindrical portion. An inner seal element has an inner metal case having cylindrical portion received on an outer surface of the stationary spindle and includes an annular portion extending radially outwardly from an end of the cylindrical portion and axially spaced from the first radial portion of the outer carrier case. An oil seal lip extends radially outwardly and axially from the annular portion of the inner metal case and engages the first radial portion of the outer carrier case.

Abstract: A nonwoven fabric has a volume-giving material, in particular fiber balls, down and/or fine feathers, and has a maximum tensile strength, measured according to DIN EN 29 073 at a mass per unit area of 50 g/m2 in at least one direction, of at least 0.3 N/5 cm, in particular of 0.3 N/5 cm to 100 N/5 cm.

Abstract: A medical valve assembly includes a tube extending between a first and second tube end along an axis, and a plunger plate extends radially from the second tube end. A valve housing surrounds the tube and includes a radially inwardly extending flange. A compression member is biased against the plunger plate and compresses an elastomeric seal from a non-compressed condition to a compressed condition to establish a sealed condition of the medical valve assembly. An inner surface of the elastomeric seal in the non-compressed condition has a plurality of planar portions and a plurality of radiused portions, with adjacent planar portions interconnected with one of the radiused portions to improve a closure of the elastomeric seal during compression. The inner surface preferably includes three planar portions and three radiused portions to define a generally triangular-shaped inner surface as viewed in cross section in the non-compressed condition.

Abstract: A mop includes a mop handle with a grip end and a mopping end. A locking cup is disposed on the mopping end. The locking cup includes a cup portion with interior threads and a locking tooth. A mop head is disposed at the mopping end. The mop head connects to a locking cap. The locking cap includes a locking tab configured to engage with the interior threads of the locking cup to allow for selective removal of the mop head from the mop handle and to engage and be retained by the locking tooth when the locking cap is threaded into the locking cup. A biasing element is disposed in the cup portion and contacts the locking cap and generate a bias between the locking cap and the locking cup and urge the locking tab against the locking tooth when the locking cap is threaded into the cup portion.

Abstract: A sealing body for dynamic applications has a Shore A hardness of between 60-100, comprising an elastomer material and carbon nanotubes distributed in the elastomer material in an amount of between 0.1-20 phr, with respect to the total amount of elastomer material.

Abstract: A method for producing a volume nonwoven fabric includes the steps of: (a) providing a nonwoven fabric raw material, containing fiber balls and binder fibers; (b) providing an air-laying device, which has at least two spiked rollers between which a gap is formed; (c) processing the nonwoven fabric raw material in the device in an air-laying method, the nonwoven fabric raw material passing through the gap between the spiked rollers, fibers or fiber bundles being pulled from the fiber balls by the spikes; (d) laying on a laying apparatus; and (e) thermally bonding so as to obtain the volume nonwoven fabric.

Abstract: Disclosed is a sealing device for a rotary shaft, including a seal mounted fixedly in a passage through which the shaft passes, providing a sealed barrier and consisting of a bearing ring with an external axial flange and a radial flange, and a sealing washer attached to the bearing ring, surrounds the axial flange and extends inward along that face of the radial flange that faces toward the outside, to end in a sealing lip bearing slidingly against the rotary shaft to be sealed, the sealing device also including a protective unit protecting against contaminants. The protective unit includes an additional ring which is secured to the rotary shaft, which is positioned on the exterior side of the seal, and which includes a radial flange which, in collaboration with the radial flange of the bearing ring of the seal, forms an annular structure of the chicane or labyrinth type.
