Abstract: ABSTRACT       Optical fibres and graded index optical cables of improved bandwidth, especially intended for use in a communi-cations system.  It has proved impossible to manufacture consistently correctly compensated graded index optical fibres.  According to this invention over-compensated and under-compensated graded index fibres or cable sections are connected alternately so that each fibre or cable section tends to correct the modal dispersion originating in the previous fibre or cable section, giving a narrower overall impulse response and hence a better bandwidth.  This arrangement also substantially reduces the variation of bandwidth with source wavelength.

Abstract: ABSTRACT OF THE DISCLOSURE Nickel base superalloy single crystal articles formed from a particular alloy and heat treated are described as is the process employed.  The resultant articles are substantially free from the grain boundary strengtheners such as carbon, boron, and zirconium and contain only a limited amount of cobalt.  As a result of the alloy composition, the alloys have a high inci-pient melting temperature.  The heat treatment process homo-genizes the microstructure, and refines the gamma prime morpho-logy.  The alloy has particular utility in the fabrication of airfoils (blades and vanes) for use in gas turbine engines. In particular, the strength of articles made according to this invention makes them especially suited for use as blades in gas turbine engines.

Abstract: ABSTRACT OF THE DISCLOSURE A layered film of thermoplastic material is defined by a plurality of superposed layers, the material forming a pair of adjacent layers having molecular chains oriented in certain directions which respectively cross each other at an angle in a range of between 5° and 90°; the film is manu-factured by heating solid thermoplastic material to its softening point, conveying the viscous molten mass so formed while mechanically working the same to an annular material shaping opening of a rotary die or matrix from which the material is discharged in the form of a tubular segment which is directed into the nip defined by a pair of rotating stretching cylinders which flatten the tubular segment to form the layered film and which are rotated at a speed which tends to orient the molecular chains in an axial or machine direction; gas is injected into the space defined within the tubular segment which tends to orient the molecular chains in a circumferential or transverse direction; according to the invention, the die is rotated at a certain speed which, in combination with the take off speed of the rotating cylinders and the blow ratio acts to relocate the frost line of the tubular segment so that the desired molecular orientation is imparted to the film layers prior to the solidification of the viscous molten material.
