Title: Subscriber unit for wireless digital telephone system
Inventor: CRITCHLOW DAVID N
IPC: H04B1/40
Filed: 1989-08-16
Granted: 1996-11-26
Abstract: A digital wireless subscriber telephone unit for wireless connection with a base station.  The subscriber unit has a baseband processor which is coupled to storage means for the baseband functions.  The baseband processor is direct access  coupled  to  a  modem  processor  whereby  the  two processors may communicate with each other.   The modem processor generally  acts  as  the master  in  the  system, although lock-out means may be used in certain circumstances. The signal from the modem processor is converted to an analog signal, which is subjected to deglitching, and the deglitched signal is then upconverted and filtered to form an IF signal which is thereafter amplified.  The amplified IF signal is combined with a signal generated by a synthesizer to provide an RF signal.  On the basis of certain signals received from the base station, the baseband processor produces initiating signals which determine whether the subscriber unit will be in the transmit mode or the receive mode.   In intervals between actuation of the system, a training mode is used wherein a known signal from the modem processor is compared with looped-back signal to produce correction constants to compensate  for undesirable variations  in  the  IF,  these constants being stored for use in correcting actual received signals.  During demodulation, the modulated digital signals are  fed  to  the  modem  processor  in  the  form  of  time multiplexed I and Q samples and are demultiplexed.   The demultiplexed I and Q samples are fed to an equalizer and frequency correction circuit for minimization of errors and for production of a frequency correction signal which is used to correct any errors in the timing of the system and in the output of the synthesizer.

Abstract: A method of manufacturing and a use of a compression resistance and high stable surfacing mass for heavy loaded surfaces, especially for strong traffic and heavily loaded street and road sections and mainly comprising a stone material which is bound by an asphalt mass. The surfacing mass is manufactured by heating asphalt at least to the recommended temperature for mixing asphalt with a stone material, and before or after the admixing of asphalt with the stone material a fibre material is added, especially a mineral fibre having an average fibre diameter of between 1  mu m and 5  mu m in an amount of about 0.5-20% of weight in relation to the asphalt weight, and the fibre material is mixed homogenously so as to throughout provide substantially separate fibres in the asphalt phase. When admixing the fibre material before adhesion of the asphalt to the stone material the temperature of the asphalt is preferably increased to 20-40 DEG C above the temperature for mixing the asphalt mass into the stone material, and after a homogenous mixing of asphalt and fibre the asphalt mass is cooled to the said admixing temperature, whereupon the asphalt-fibre mass is mixed homogenously with the stone material.

Abstract: A pharmaceutical oral controlled release multiple-units formulation in which individual units comprise cross-sectionally substantially homogeneous cores containing particles of a sparingly soluble active substance, the cores being coated with a coating which is substantially resistant to gastric conditions, but which is erodable under the conditions prevailing in the small intestine, in particular an enteric coating which is substantially insoluble at a pH below 7 such as Eudragit<sup>0</sup> S (an anionic polymerisate of methacrylic acid and methacrylic acid methyl ester), is prepared by a process comprising comminuting an active substance together with a substance which is readily soluble in intestinal fluids such as an anionic detergent to obtain particles containing the active substance in intimate admixture with the readily soluble substance, combining the resulting particles into cross-sectionally substantially homogeneous cores together with components which accelerate the disintegration of the cores in intestinal fluids such as talc and sucrose, coating the individual cores with the coating, and combining a multiplicity of the coated cores into a capsule or tablet formulation.As the coating is erodable in an alkaline environment only, the active substance is not released until the units arrive at a section ofthe small intestine with an alkaline pH. Thus, a reduction and delay of the peak plasma concentration is obtained without affecting the extent of drug availability.A coating of the above-defined type may also be used when the active substance is a substance which exerts an irritating effect on the gastric mucosa and/or is unstable in an acidic environment.
