A device for cleaning U-profile sections (2) comprises a brush roll (8), engaging the base of the section from the outside and provided with bristles (14) oriented perpendicularly to the axis of rotation of the roll, and two further brush rolls (4, 5) with bristles (20, 27) forming an acute angle (.alpha.) with the axis of rotation (24, 26) of the brush rolls (4, 5). The brush rolls (4, 5) with bristles (20, 27) inclined in opposite directions with respect to their axes of rotation (24, 26) are ...

A clamping mechanism comprises a first clamp half 20 and a second clamp half 22. The first clamp half 20 and the second clamp half 22 contact a linear guide rail 14 at one end thereof and a key 12 at another end thereof, with the key 12 being coupled to the moving member. A plurality of threaded shafts 40 pass through both the first clamp half 20 and the second clamp half 22 while also passing between the linear guide rail 14 and the key 12. A plurality of cooperating nuts 42, 44 are provided on...

A precured tire tread for use in retreading tires contoured to have a flat road-contacting tread surface when applied to the casing.

A profiled insulating underboard for insulating and aligning metal or plastic siding panels is disclosed. The underboard is formed from a suitable insulating material into a sheet having one substantially flat planar surface and an opposed surface with a configuration or profile which corresponds to the inner contour or profile of the siding panel so that it will fit snugly against the inner surface of the siding when installed. Each sheet of underboard, which is received against the exterior wa...

A coupling assembly includes a female member having a receiving end with an axially extending passageway and inwardly facing groove extending outwardly from said passageway in a position spaced from the receiving end. A split metal locking ring is positioned in the groove. A male member is sized to be received in said receiving end and includes a rib having a ramp where the ramp in a first embodiment curves outwardly to an apex and in a first alternate embodiment curves outwardly to a flat and i...

A profiled hinge joint having joint wings designed in the form of profiled frame members, one joint wing being provided with a bead member extending longitudinally with the frame member, the other joint wing having a partially open, cap-shaped flange engaging the bead member and likewise extending longitudinally with the frame member.

An electrical connector system includes a first connector having at least one receptacle contact and a second connector having at least one pin mated to the at least one receptacle contact. The pin may have a stem and a tip attached to the stem. The pin tip is designed to prevent misalignment of the pin or "pin side track" when mated to the receptacle contact and the mating forces that result from side tracking. In order to prevent this side tracking, the pin end may have a first flat side, a se...

A profiled guide rail, for use in providing a guide path for a roller chain in a web-fed rotary printing press, utilizes a plurality of slits as paths through which ink particles and paper dust can pass out of the track in the guide rail along which the roller chain travels. These slits pass through at least one leg of the guide rail and are longitudinally spaced in the direction of travel of the roller chain.

The invention relates to a profiled sheet for building purposes, especially roofing and facade sheet, the sheet having a normal profiling and having in addition, at least in certain sections, a corrugated microprofiling deviating from the normal profiling. The microprofiling exhibits flattened and/or pressed-in areas in its crest, valley and/or flank sections resulting in that the thickness of the profiled sheet varies in a direction transversely of the longitudinal direction of the microprofili...

A profiled band that includes two longitudinal edges of which one is provided with a groove and a parallel extending rib is allocated to the other one, which mentioned parts form a locked seam when the band is wound to a pipe, which seam is mechanically held in its operational position. The band is specifically suitable for an in situ production of wound pipes having a helically extending seam.
