    • The abstract was not in accordance with PCT Rule 8.1 (b) because it was more than 150 words in length. The abstract has been established by this Authority to read as follows: A process for producing high impact polystyrene including feeding at least one vinyl aromatic monomer; an elastomer, and a free radical initiator to a first linear flow reactor to form a reaction mixture. Polymerizing the reaction mixture in the first linear flow reactor to a point below the point at which phase inversion occurs to produce a first polymerization mixture and feeding the first polymerization mixture from the first linear flow reactor to a second linear flow reactor. Polymerizing the reaction mixture in the second linear flow reactor to at least a phase inversion point of the mixture to produce a second polymerization mixture and feeding the second polymerization mixture from the second linear flow reactor to at least a third linear flow reactor for post.inversion polymerization of the second polymerization mixture.

    • A transmitter shifts a baseband data signal having a bandwidth of 2O>M using a tone signal having a frequency 6>M, which centers a sideband of the data signal at zero frequency. The transmitter then filters the shifted signal to filter out the non- centered sideband, and then adds the tone signal to form a composite signal. The transmitter upconverts the composite signal during a first operational mode using a RP signal having a frequency ωc equal to a center frequency of a channel. In a second operational mode, the transmitter upconverts a DC level using the same RF signal. The upconverted DC level can be used as a continuous wave carrier signal having a frequency ωc- The transmitter has a single RF oscillator to output both a SSB signal centered at frequency ωc during the first mode and a carrier signal of frequency ωc during the second mode.
    • 发射机使用具有频率6> M的音调信号来移动具有20MHz带宽的基带数据信号,该频率使数据信号的边带以零频率居中。 然后,发射机对移位的信号进行滤波以滤除非中心边带,然后将音调信号相加以形成复合信号。 发射机在第一操作模式期间使用频率ωc等于信道的中心频率的RP信号来上变频合成信号。 在第二种操作模式中,发射器使用相同的RF信号上变频DC电平。 上变频DC电平可以用作具有频率ωc的连续波载波信号。发射机具有单个RF振荡器,以在第一模式期间输出以频率ωc为中心的SSB信号,并且在频率ωc期间输出频率ωc的载波信号 第二种模式。
