Abstract: A process is disclosed for the solid phase preparation of triaxially oriented synthetic polymeric material from an orientable amorphous but crystallizable or a semicrystalline thermoplastic polymeric workpiece comprising (a) presenting the conditioned workpiece, at the entry mode of an opposing pair of solid rollers that are spaced apart a distance substantially less than the thickness of the workpiece; and (b) deforming the workpiece by compressive passage through the paired rollers at a nominal deformation ratios of at least 2 to 1. The deformation drawing is carried out between the glass transition temperature and the melting point of the polymeric material, by applying a draw tension insufficient to cause tensile failure of the workpiece. Also disclosed is a rolltruded copolymer membrane or film-like material with a triaxial orientation morphology with a periodicity consisting essentially of crystallite and amorphous materials or a periodic distribution or crystalline and intercrystalline tie regions.

Abstract: An anti-tip hinge device for a door or a shelf, which is pivotally moved to obtain a horizontal cantilever position. The hinge device has a channel which fits into a sheath of and is connected to the door or shelf. A lever arm carries cam followers which engage a cam in the channel. The cam is supported in the channel by a pin and a spring located on opposite ends of the cam. The cam has a recess and a ramp disposed adjacent to the recess. When an overload is applied to the cantilever end of the door or shelf, the cam followers are disengaged from the recess of the cam, and push the cam inwardly within the channel at an angle to allow the door or shelf to be titled downwardly below the horizontal. This action interrupts the counterbalance spring effect on the door. A pin-hole arrangement resets the hinge device, and a lug-slot arrangement prevents the door from disengaging the hinge device.
