Patent DK-149360-C (DK)
Inventor: ASH CHRISTOPHER PATRICK
IPC: H04B3/06
Filed: 1980-09-19
Granted: 1987-01-19
Abstract: The presence of a d.c. offset in the input signal to an adaptive equalizer for a high speed modem must be removed before a valid signal enters the equalizer if the "coefficient up-date" algorithm for the equalizer is not to be confused. Normally the d.c compensation is achieved using adjust-on-test resistors or potentiometers which provide for in life adjustments to compensate for ageing drift. The submission envisages the use of an additional adaptive equalizer tap-stage connected to a fixed voltage source. This voltage is multiplied by the additional tap-stage multiplier and summed with the outputs of the other tap-stages in the equalizers accumulator. The error produced from the equalizer decision circuit is correlated with the fixed voltage in the additional tap-stage correlator the output of which controls the gain of the additional tap-stage multiplier thereby compensating for the original d.c. offset of the output of the equalizer accumulator.

Abstract: A method of and apparatus for fusion bonding a continuous synthetic thermoplastic resin fastener strip having a fastener profile portion and a base portion opposite the profile, to a continuous film substrate. The substrate is advanced continuously through a bonding zone. Continuous direct transit of the fastener strip is effected from thermoplastic extruder downwardly through a short distance to the bonding zone, so that in the short transit distance the fastener strip will retain substantial residual thermoplastic fusion temperature. The fastener profile portion is chilled while the strip is in transit to the bonding zone, solidified and stabilized, but the base portion is left at sufficient residual fusion temperature to remain thermoplastic to the bonding zone where assembly of the strip and substrate is effected by fusion bonding of the base portion to the substrate. An annular rotary heating surface may be applied to a narrow locally limited longitudinal area of the substrate for supplying to such area fusion promoting heat in the bonding zone, such area being aligned with the fastener strip in the assembly. The longitudinal area may be stretched by the rotary heating surface.

Inventor: AULA JOUKO
IPC: D21F3/10
Filed: 1990-12-06
Granted: 1996-04-09
Abstract: The invention concerns a suction roll (10) for a paper making machine, on which the paper web is pressed towards the outer face of the roll mantle.  The suction roll (10) is divided, in the axial direction of the roll, into at least three vacuum spaces (A1, A2, A3).  In the interior of the suction roll (10), there are at least two partition walls (17a, 17b), by means of which the suction space (13) is divided into separate zones of negative pressure.  The lateral vacuum spaces (A1, A3) in the suction space can be subjected to a higher negative pressure than the vacuum space (A2) in the middle area of the roll, whereby the profile of negative pressure is formed such that the negative pressure increases across the width of the roll towards the lateral areas.  The invention also concerns a method for producing a desired pressure profile for a suction roll.

Title: Demodulation control arrangement in satellite communications system using "scpc-dama"
Inventor: HIGASHIJIMA SATORU
IPC: H04J1/00
Filed: 1990-12-14
Granted: 1995-05-23
Abstract: In order to effectively demodulate an incoming RF signal which takes the form of bursts in a satellite communications system using a Single Channel Per Carrier Demand Assigned Multiple Access (SCPC-DAMA) technique, a controller is provided which is operatively coupled to a down-converter and a demodulating section.  In the event that the RF signal is a continuous signal, the controller routes an AGC signal, which is outputted from the demodulating section, to a first variable attenuator provided in the down-converter and applies a constant potential to a second variable attenuator within the demodulating section.  On the other hand, in the event that the RF signal assumes the burst format, the controller retains a value of the AGC signal at the time when the RF signal undegoes the continuous-burst change and applies the retained value of the AGC signal to the first variable attenuator.  The controller further allows the AGC signal to be applied to the variable attenuator while the RF signal takes the form of the bursts.
