Abstract: The invention relates to a polymer blend, a process for the preparation thereof and products manufactured from the polymer blend. The polymer blend contains 95 to 50 parts by weight of a polyolefin- or polyester-based polymer matrix, 5 to 50 parts by weight of an aromatic main-chain liquid crystalline polymer, and plastic additives, if any. Further, the blend contains, based on the total weight of the previous components, 0.1 to 30 per cent by weight of a substance (a compatibilizer) which improves the compatibility of the polymer matrix and the liquid crystalline component. According to the invention, the compatibilizer comprises a polymer containing reactive, functional groups. Preferably the compatibilizer comprises a SEBS polymer functionalized with maleic anhydride or an olefin polymer functionalized with glycidyl methacrylate. Having excellent tensile, flexural and impact strength, the polymer blends according to the invention, can be used for the manufacture of tubes, pipes, sheets and fibres. They are suited, e.g., for manufacture of constructional parts of electrical and optical cables.

Abstract: Mechanical cellulosic fibrous material pulp (mechanical pulp to produce paper products) having lower freeness, and enhanced light scattering properties, tensile and tear strengths, for a given energy input, is produced by force feeding a refiner (10). Using a progressive compacting plugscrew (12,46,48), cellulosic material (e.g. wood chips) is fed to the refiner inlet (15) at a rate greater than the transporting capacity of the refiner (e.g. about 10-40% greater). The refiner preferably is a low frequency conical refiner with steam removal (22) at the grinding area between the conical refiner elements (18,19). The production rate is regulated by sensing (via 32) the axial force on the refiner rotor and controlling the spacing (21) between the refiner elements (18,19) in response to the sensed axial force. The screw has a compaction ratio of at least 3/1 for wood chips and 6/1 for pulp, and is rotated at about 6-10% the speed of rotation of the refiner rotor.

Title: Process for manufacturing high-purity o-toluic acid

Granted: 1997-03-25
Abstract: A process  for manufacturing high-purity o-toluic acid from a partial oxidation product of o-xylene is disclosed.  o-Toluic acid is widely used as a raw material for agricultural chemicals, medicines, polymerization initiators, and the like. Depending on its use, 99% by weight or more purity is demanded for o-toluic acid.  Hitherto, o-toluic acid having purity of higher  than  99%  by  weight  could  not  be  obtained  by fractionation, and purification by fractional crystallization was  used.    Fractional  crystallization  is,  however, an expensive operation and not only gives a low yield of product but also results a large amount of waste water.  The process disclosed herein gives an economical, commercial way to obtain high purity o-toluic acid.   In summary,  a process for the manufacture  of high purity o-toluic  acid which comprises: subjecting an oxidation product of o-xylene to distillation to remove  therefrom  low  boiling  point  components  such  as unreacted o-xylene and benzoic acid,  and high boiling point components, of which the major component is o-methylbenzyl o-toluate,  thus obtaining crude o-toluic acid,  treating said crude o-toluic acid with ammonia of an amount 1 to 1.2 mol equivalent of o-phthalic acid contained in said crude o-toluic acid, and subjecting the product thus treated to distillation is disclosed.

Abstract: Method and apparatus for use in a global positioning system,(GPS), to obtain the benefit of L2 carrier signals and precise-code (P-code) signals transmitted from satellites in encrypted form. Received, encrypted P-code signals are correlated with a locally generated P-code sequence and the resulting signal is band-pass filtered and squared, to separate one satellite signal from the others, to recover the carrier signal and make accurate measurement of its phase and pseudo-range, even though the received P-code sequence is encrypted. Because the squaring step is performed over a narrower bandwidth than the original P-code, there is less degradation in the signal-to-noise ratio of the received signal, as compared with squaring over the entire P-code bandwidth. Therefore, performance is more reliable under weak signal conditions or when there are interference signals present, and the improvement in signal quality means that cycle ambiguity of the carrier signals can be resolved more rapidly. Moreover, the invention does not frustrate the intended purpose of P-code encryption.

Abstract: On carrying out connected word recognition in compliance with a regular grammar and in synchronism with successive specification of input feature vectors of the input pattern, one of an n-th word (n) of first through third occurrence (n(1) to n(3)) is selected as the n-th word of selected occurrence in an i-th period in which an n-th input feature vector is specified.  The n-th word appears as the first through the third occurrence in transition rules specified by the grammar.  In the n-th period, distances are calculated, only for the n-th word of the selected occurrence, between the input feature vector assigned to the i-th period and reference feature vectors for the n-th word.  In the i-th period, a recurrence value g(n, i, j) is calculated only for the n-th word of the selected occurrence under a boundary condition T(p, i-l) iteratively in correspondence to the reference feature vectors by using the distances calculated for the n-th word of the selected occurrence before the i-th period, where j represents each feature vector.  The recurrence value for the n-th word of nonselected occurrence is estimated by using the recurrence value for the n-th word of the selected occurrence and the boundary conditions T(p, i-l)'s for the n-th word of the selected and the nonselected occurrence.  The above-mentioned one of the n-th word of the first through the third occurrence is selected so as to have a minimum value of the T(p, i-l)'s.

Abstract: A microprocessor-controlled remote resistance measurement system is disclosed wherein the connection leads to the three- or four-wire resistance temperature devices (RTDs) are multiplexed via a four-channel analog multiplexer at the input of the unit. A separate two-channel multiplexer is also used to multiplex a fifth input for measurement of a reference resistor. The output of the multiplexer is coupled to a voltage-to-frequency converter, wherein the frequency output is utilized as an input to the microprocessor-based controller. The microcontroller can check for broken wires by addressing the multiplexers to individually isolate any of the connecting wires to the remote RTD sensors. The output of the multiplexer is monitored in a Test Mode by connecting a known impedance to the multiplexer output to determine if any RTD connections are defective. If one of the voltage sensing wires is faulty, the known impedance will cause an erroneous frequency reading into the microcontroller, which will then provide an indication on the display for determining exactly which RTD wire is broken. Only two address lines are used to control the five multiplexer channels through the use of a function selector circuit and a two-stage measurement cycle.

Abstract: Wax and waxy feeds are hydroisomerized by contacting the wax or waxy feed under isomerization conditions with a catalyst comprising a thin outer shell of catalytic material bonded to an inner core of catalytically inert material. The catalyst is made by coating a catalytically inert core such as alpha alumina, with a thin layer of finely divided catalytically active material in a slurry of colloidal boehmite/pseudo boehmite then calcining to convert the boehmite/pseudo boehmite into alumina which bonds to the inert alumina core.      Catalysts made by this technique for hydroisomerization contain an outer shell of platinum on fluorided alumina on an inert core of alpha alumina.
