Title: Process and device for adjusting digital equilization filter at simultaneously adaptive ellimination of echo effect and noise, which arises from intersymmbolic interference
Inventor: BAUER A G
IPC: H04B/
Filed: 1986-04-21
Abstract: PCT No. PCT/SE86/00162 Sec. 371 Date Dec. 12, 1986 Sec. 102(e) Date Dec. 12, 1986 PCT Filed Apr. 8, 1986 PCT Pub. No. WO86/06567 PCT Pub. Date Nov. 6, 1986.In particular, there are provided in accordance with the invention a method and apparatus for adjusting a digital equalizing filter in a hybrid circuit in a telecommunication system for transmitting digital information in duplex on a single line pair with simultaneous adaptive echo elimination and adaptive elimination of noise caused by intersymbol interference, where a first and a second compensation signal (e(t), i(t)), which are respectively dependent on the stored parameters of a digital balance filter and an equalizing filter, are subtracted from a received signal (a(t)+e(t)+i(t)) to form a difference signal (r(t)) which is compensated for noise respectively caused by echoes and intersymbol interference, the balance filter parameters being corrected with the aid of a correction signal ( epsilon B kappa ) dependent on the difference signal (r(t)). The equalizing filter parameters are adjusted with the aid of a further correction signal ( epsilon U kappa ) formed by the balance filter correction signal ( epsilon B kappa ) and the first compensation signal (ê(t)) such that the further correction signal ( epsilon U kappa ) will substantially agree with the balance filtercorrection signal ( epsilon B kappa ), but obtain the value zero when the first compensation signal (ê(t)) and the balance filter correction signal ( epsilon B kappa ) are both positive simultaneously or negative simultaneously. There is thus prevented the correction sequence of the equalizing filter parameters when the balance filter parameters are changed in a direction such that the absolute value of the estimated echo (ê(t)) increases.

Abstract: ABSTRACT OF THE DISCLOSURE   It has been suggested that antistatic properties of fibers of polyamide could be improved by uniformly dispersing in the polyamide between about 1 percent and about 12 percent by weight of a predominantly branched, chain-extended propylene oxide-ethylene oxide copolymer base on a diamine.  However, with incorporation of this antistatic additive in the polyamide, serious problems have been encountered in melt-spinning due to the frequent occurrence of the "nuba" or enlarged places in the extruded polyamide filament.  It has now been found that the occurrence of said nubs in the antistatic polyamide fiber can be greatly reduced by dispersing in the polymer at least 0.5% by weight, based on the weight of the antistatic agent, of a phenol compound represented by the formula:                         where R is an alkyl hydrocarbon group containing less than nine carbon atoms and H2 is a tertiary alkyl group containing at least four but not more than 12 carbon atoms.

Abstract: ABSTRACT OF THE DISCLOSURE   The invention is a process in which a pyrolysis naphtha contain-ing olefinically unsaturated components is heated in the presence of water, thereby polymerizing the olefinically unsaturated components and yielding a treated naphtha.  As the olefinically unsaturated components of pyrolysis naphtha form gums during heat treatment and distillation and also contribute to foul odours, low volatilities, poor stability and low octane values of pyrolysis naphthas, their removal by polymerization yields a treated naphtha which is a more valuable product than pyrolysis naphtha.  In a preferred form of the invention treated naphtha is subjected to hydrogenation which yields a naphtha containing aromatic components which can be recovered.

Abstract: STABILIZATION CIRCUIT FOR RADIATION EMITTING DIODES          Abstract of the Disclosure A particularly important factor limiting the reliability of diode lasers is the catastrophic mirror damage which occurs when the radiated output exceeds a critical value.  Experience has shown that this occurs  as a result of fluctuations in the drive current, especially in high efficiency diodes.  To avoid such damage, a portion of the output radiation from a diode laser, located in the collector circuit of a common emitter drive transistor, is coupled back to a photodetector, located in the base-emitter circuit of the transistor.  The resulting negative feedback tends to stabilize the overall operation of the device and maintain the maximum radiated power within safe limits.

Abstract: REGENERATIVE MOTOR CONTROL HAVING      IMPROVED FIELD CIRCUIT                 Abstract of the Disclosure The field circuit of a regenerative d.c. motor control provides rapid reversal of field current by dis-charging the inductive energy of the winding back to an alternating current power supply for the field.  This is accomplished by firing thyristors in the field circuit late in the half cycles of alternating current by means of an improved firing circuit.  The firing circuit includes a pair of firing pulse generators coupled to the thyristors, one for each direction of field current.  Each of the pulse generators has a control signal generator for providing a firing control signal to the pulse generator.  A bias circuit, such as a voltage divider, is connected to the control signal generator to obtain actuation of the pulse generators and the firing of the thyristors late in the half cycles.          The control signal generator also receives the input signal from the regenerative control for increasing the magnitude of the control firing signal beyond that provided by voltage divider to provide motor field current in accordance with the input signal.
