Abstract: ABSTRACT OF THE DISCLOSURE        Objectionable noise is inhibited in sheet spreaders of the type wherein strips of a slit travelling web are laterally separated by running the strips over spaced, bowed hollow spreader bars, frictional resistance being alleviated by floating the strips on a layer of air covering the areas of the bars wrapped by the strips.  Tendency toward high frequency vibration and thus noise experienced in high spaced operation is inhibited by ventilation in the tangency angles between the bars and the running strips.     -i-

Abstract: CRIMPED HOLLOW FIBERS FOR FLUID SEPARATIONS AND BUNDLES CONTAINING THE HOLLOW FIBERS ABSTRACT OF THE DISCLOSURE Hollow, semi-permeable fibers which are intended for use in fluid separations axe provided with relatively low amplitude waves, or crimps. The relatively low amplitude crimps enable the hollow fibers to be assembled in a bundle comprising substantially parallelly-oriented hollow fibers wherein the bundle has a relatively high packing factor, i.e., the percentage of the cross-sectional area of the bundle occupied by hollow fibers, such that unduly large volumes of separation apparatus are not required for a given amount of hollow fiber surface area. The relatively low amplitude crimps enable good fluid dispersion through a bundle comprising substantially parallelly-oriented hollow fibers such that shell-side (i.e., the exterior sides of the hollow fibers) feed of the fluid mixture to be treated can be attractive, even when the flow of the feed is predominantly axial to the hollow fibers. Shell-side feed of the fluid mixture to be treated is often particularly advantageous since the fluid mixture can frequently be recovered from the fluid separation with a relatively low pressure drop.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to an arrangement for measuring the range or speed of an object, in which two optical devices are offset from one another transversely to the direction of the object to produce auxiliary images of such an object, which are photoelectrically analyzed relative to one another.  The minimum difference signal indicates the congruency of the two auxiliary images and supplies a criterion for the range of the object.  In accordance with the invention, the auxiliary images are analyzed by CTD image sensors, whose read-out signals arc supplied to a differential ampli-fier and are then rectified and integrated. The read-out signals from one sensor are changed, as to their phase state, with respect to the read-out signals from the other sensor, by means of a pivotal movement of the relevant optical device, by means of a delay element which can be adjusted in a stepped manner.  The range criterion is obtained from the phase state assigned to the minimum difference signal.  The invention can be used in range measuring devices, speed measuring devices and photographic cameras.

Abstract: DECENTRALIZED GENERATION OF SYNCHRONIZED            CLOCK CONTROL SIGNALS             Abstract of the Disclosure In a microprogrammed processor consisting of several circuitized chips, which are to be synchron-ously operated, each chip is provided with its own local clock generator or T-ring for deriving there-from timing signals required during the subphases of micro instruction execution.  A master clock connected to all of the T-rings by lines of equal length forces the individual T-rings to operate synchronously and keeps them operating in such a manner.  In addition, reset circuit means is provided for forcing all of the T-rings to their first timing interval for ini-tial synchronization thereof or, at an appropriate time, when a micro instruction requiring less than the maximum number of available T-ring timing signals is executed.  The timing signals which are locally produced are subject to little delay on their way to the various local switching points.  Thus, the entire system can be operated at a higher oscillator or master clock frequency to take advantage of the enhanced processing and transfer speeds of modern, highly integrated circuit chips.
