Abstract: Abstract of the Disclosure A composite alumina-zeolite adsorbent exhibits synergistic properties for the adsorption of fatty acid compounds from refrigerant gases.  A composite adsorbent takes up about 30 mg. of fatty acid per gram of adsorbent, while alumina takes up about 21 mg. of fatty acid and zeolites about 9 mg. of fatty acid per gram of adsorbent.  A simple comixture would be expected to take up in the range of 9 to 21 mg. of fatty acid, depending on the composition, but the alumina-zeolite composite adsorbents will instead take up about 30 mg. It has also been found that alumina-zeolite composites can be substantially strengthened by a moisture treatment.

Abstract: MANUFACTURE OF FLAT GLASS HAVING CONTROLLED WIDTH AND NIP WIDTH            Abstract of the Disclosure Apparatuses of the type used for attenuating a body of hot glass supported on and moving along a body of molten metal are each provided with a nip sensing device, a linear movement monitoring device and an angular movement monitoring device.  The nip sensing device includes a plurality of discrete phototransis-tors connected to an electric circuit. The phototransistors are positioned over the glass and molten metal in a direction gener-ally transverse to the direction of glass movement.  When selected ones of the phototransistors are conducting, the nip width of the ribbon is within a predetermined range.  When the selected ones of the phototransistors are not conducting, the circuit operates to appropriately energize a carriage motor to appropriately move a barrel assembly of the apparatus with respect to the edge of the ribbon to provide a nip width within a predetermined range.  The linear movement monitoring device includes a potentiometer which is connected by way of a spring-biased wheel and cable to the barrel assembly.  The output of the potentiometer is monitored to determine the width of the ribbon, the output of the potentiometer of opposed attenuating apparatuses is monitored to determine the width of the ribbon.          The angular movement monitoring device includes a potentio-meter which is connected by way of a spring-biased wheel and cable to a plate mounted on the floor.

Abstract: Abstract of the Disclosure Molding resin compositions comprising a polycarbodiimide modified polyalkylene terephthalate polymer (polypropylene terephthalate, polybutylene terephthalate, or mixtures thereof) and a reinforcing agent such as glass fibers have been found to exhibit improved impact strength and thus are useful in various molding applications in order to prepare articles of manufacture having, e.g., industrial (e.g-, gears, bearings), automotive (e.g., automotive distributor caps, distributor rotors), and electrical (motor end caps, brush holders) applica-tions.  These molding resin compositions are particularly useful in certain automotive, industrial, and electrical applications where greater impact strength may be required to extend the useful life of various articles of manufacture which way be subjected to occasional or continuous shock or impact.       These molding resin compositions may be prepared by intimately admixing in the molten state a reinforcing agent such as glass fibers with a polycarbodiimide modified polyalkylene terephthalate polymer formed from the reaction between a polyalkylene terephthalate polymer and a polycarbodiimide which is both (1) derived from at least one aromatic diisocyanate which is either unsubstituted or contains up to one methyl substituent on each aromatic ring, and (2) contains at least two carbodiimide units per polycarbodiimide molecule.  The components of the composition are preferably prepared by charging the polyalkylene terephthalate to the hopper of a melt screw extruder and adding the polycarbodiimide and reinforcing agent downstream in the extruder -- e.g., in the vent port or other side feed port of the extruder.

Abstract: A B S T R A c T          In a pneumatic dryer, a material which gives off an odorous exhaust during drying is dried in a first dryer section by a stream of hot gas, the major part of the spent gas stream being re-heated by the addition of air and burning fuel under pressure to form the said stream of hot gas   The excess spent gas in the first dryer section is passed through an incinerator to pyrolyse the odorous content of the spent gas stream, and the pyrolysed gases are used to dry a second wet material in a second dryer section and are then passed to atmosphere.  The second wet material does not give off an odorous exhaust.  In a modified method a wet material which gives off an odorous exhaust when the moisture content of the material falls below a critical value during drying is dried in the second dryer section to a moisture content having a value above the critical value and is then dried to completion in the first dryer section   The heat added to incinerate the said excess spent gas from the first dryer section should be slightly in excess of what is necessary for the pyrolysation of the odorous matter therein, and all the available heat in the hot gas stream from the incinerator should be usefully employed in drying the wet material in the second dryer section.

Abstract: ABSTRACT OF THE DISCLOSURE:           In a time-division digital transmission system comprising transmitting and receiving stations interconnected by transmission lines, a number of component digital channels having a low flow rate are multiplexed into a single resultant channel having a high flow rate.  The code used in the stations is a binary code and the code used in the lines is a multi-level code such that a number N of bits in the binary code corresponds to a smaller number N' of elements of the multi-level code.  Consequently, a given flow rate in the station corresponds to a smaller flow rate in the line, equal to N'/N times the flow rate in the stations.  The system comprises, on its transmitting side, means for placing in parallel the bits of a number of component channels equal to a multiple k of N, at the rate of one bit per component channel, so as to form parallel words of kN bits and, on its receiving side, means for distributing the bits of the parallel words of kN bits at the rate of one bit on each of the kN component chan-nels.  The system further comprises, on its transmitting side, means for multiplexing the bits of the parallel words of kN bits into k parallel words of N bits, means for converting the parallel N-bit words from the binary code used in the stations into parallel words of N'elements in the multi-level code used in the line, and, on its receiving side, means for con-verting the parallel words of N' elements of the multi-level code used in the line into parallel N-bit words of the binary code used in the stations, means for forming parallel words of kN bits out of a number k of N-bit words supplied by the latter said converting means and means for demultiplexing the parallel kN bit words into kN bits at the rate of one bit per component channel.

Abstract: Abstract of the Disclosure In a method of manufacturing a tube coil useful as a heat exchanger, wherein a plurality of tubes, guided in parallel and slightly spaced, are wound onto a core support, the tubes are wound at a pitch angle to the radial plane of the core support, and the pitch angle is reversed relative to said radial plane at an odd number of angularly spaced positions around the coil, such that the separate tubes of a subsequent winding turn can be positioned in the gaps between adjacent tubes of the preceding winding turn at those posi-tions.  The core support has a polygonal e.g.  three- or five-sided cross section and the pitch angle is reversed at the polygon corners of the core support.  The tubes are guided in parallel by means of a guide comb, which is displaceable in the axial direction of the coil.  Reversal of the winding direction is accomplished by reversing of the displacement direction of the guide comb, and the tubes are braked by means of the guide comb.
