This invention relates to an apparatus for continuously extruding a viscous material having discontinuous reinforcing fibers therein. The apparatus has a rotating extruder head assembly including an extruding die having an extruding passage. A plurality of vanes extend outward from the extruding passage. In response to rotation of the extruder head assembly the fibers are orientated on a helix about a mandrel.

Apparatus for extruding a viscous material

A shear loaded face seal having means for increasing the torque transfer capacity of the shear loaded face seal between its support ring and its load ring along their mating interface is disclosed. In such a shear loaded face seal, the load ring is of a deformable rubber and the support ring is rigid. A varying torque is transmitted through the shear loaded face seal along the interface between the load ring and the seal ring. The torque transfer means comprises a surface texture on the mating surfaces of the support ring that has a configuration sufficient to generate a projected area that is at least five per cent of the surface area of a non-textured surface of equivalent dimensions. The surface texture is provided by a plurality of uniformly spaced micro splines that are oriented normal to the direction of the torque.

Face seal with increased torque transfer capacity

An apparatus for providing information, for example, tourist information, comprising a sound reproducing device which can receive a prerecorded tape, such as a cassette, having informative touring information for a specific location, the apparatus being manually energizable and being shut off at predetermined points by the tape. The tape can have numbers thereon viewable by the operator and for indicating the road exit or location.
