Abstract: An optical transmission system is described wherein light is transmitted from a transmitter (Tx) to a receiver (Rx) by at least one transmission optical fiber (11). The system includes a dispersion transformer (13) which receives light from one of the components, compensates for or transforms the delay distortion of the various wavelengths transmitted through the system, and provides the next component in the system with a compensated or transformed light beam. The dispersion transformer (13) comprises means for receiving light from one of the components and dispersing/separating the light into a plurality of spatially separated beams which are directed onto the endface of a multimode optical fiber (16). The position of each beam on the endface of the multimode fiber (16) is a function of the velocity with which the light that forms the beam propagates through the transmission optical fiber (11). The multimode fiber (16) is characterized by a refractive index profile and a shape which are such that the modes excited therein are propagated therethrough with appropriate delays to generate an output pulse of desired width. Dispersion can be reduced or increased. Light emanating from the multimode fiber (16) is coupled to the next adjacent component of the system.

Abstract: A machine tool is provided for allowing complex shapes to be machined on a workpiece at high speed. The system is computer (13) controlled and receives workpiece profile data which are converted into a succession of tool position signals during machining. Not all the digital signals are calculated at one time, a number of future digital signals are calculated during a succession of time intervals. Further, for symmetrical profiles, data defining only one symmetrical portion is fed to the computer (13) which then produces digital signals for the whole profile. In each time interval, a tool position signal is outputted which is of a constant amplitude corresponding to the required tol position and which is fed to a signal processor (19) where it is converted into a signal which is used to drive a linear motor (23). Proportional and differential feedback (24, 25) are provided from the motor (23) for feedback control.

Abstract: A porous substrate is formed from discrete elements preferably anisotropic and permeable to oxygen and preferably having a first coefficient of thermal expansion. A pyrolytic material permeable to oxygen may be deposited in a thin layer on the discrete elements. A barrier material (e. g. boron carbide or silicon carbide) may be deposited in a thin layer on the pyrolytic material to inhibit diffusion of elements into the pyrolytic material. A material impermeable to oxygen (e. g. boron nitride or silicon nitride) may be deposited in a thin layer on the barrier material. A refractory matrix permeable to oxygen may be deposited on the impermeable material. The matrix may include a metallic element (e. g. silicon, hafnium, tantalum or zirconium) and another element (e. g. oxygen, nitrogen, carbon or boron) chemically bonded to the metallic element. The matrix may have a second coefficient of thermal expansion different from the first coefficient and may have a minimal bond to the substrate. The matrix is accordingly able to move relative to the substrate with changes in temperature, partly because the pyrolytic material contributes to a shear between the matrix and substrate. A refractory material impermeable to oxygen may be deposited in a thin layer on the matrix and may include a metallic element (e. g. silicon, hafnium, tantalum or zirconium) and an element (e. g. oxygen, nitrogen and boron) chemically bonded to the metallic element. The different layers may be deposited on the substrate, each in a substantially uniform thickness, at an elevated temperature and at pressures pulsating at a particular rate, and in reverse directions, between first and second particular limits.

Abstract: The invention relates to a transport load container 9 which is to be cooled by means of a refrigeration unit 10 whose refrigeration air emerges from exit nozzles 1 of a channel running below the loading container ceiling. Since the refrigeration air outlet only extends in strands, the material to be refrigerated by said air is only provided with it unevenly. A substantial improvement is achieved by the invention by arranging a grid-shaped ceiling 3 below the exit nozzles, the grid fields 4 of said ceiling being constructed with a textile fabric 5 which is permeable to the cold air emerging from the exit nozzles 1. Thanks to this distribution, the cold air flows evenly downwards from the entire surface of the ceiling and consequently covers all the objects to be refrigerated. The distance of the grid-shaped ceiling 3 from the loading container ceiling can be selected to be very small so that the height of the loading container 9 can be utilised to a large degree. <IMAGE>
