Abstract: The full-duplex type circuit of automobile  telephone  device including a switch (3) connecting to the receiving voice  line,  a microcontroller (4), an amplifier (2') and a speaker, comprises  a first amplifying means for amplificating the signal generated from the hand  set  microphone,  and  a  second  amplifying  means  for amplificating the signal generated from the  external  microphone. This circuit provides the clear  telephone  call  by  opening  the speaker channel of ringing tone in the hand set.

Abstract: 본 발명은 셀룰로우스 섬유들과 함께 재를 내포하는 리펄프된 휴지로부터 재를 제거하는 장치(10)에 관한 것이다. 
     다공성 벨트(20)는 다수의 롤(14-17) 둘레에 뻗고 그들에 의해 지지되어 무한루프(22)를 한정한다.  헤드박스(26)는 스크리닝부(24)를 통해 리펄프된 휴지를 분출하기 위해 스크리닝부(24)에 인접하고 무한 루프(22) 내부에 배치된다.  배수장치(30)는 스크리닝부를 통과하는 재를 수용하기 위해 헤드박스(26)에 관해 스크리닝부(24)의 반대측(32)에 배치된다. 
     샤워(34)는 벨트(20)가 외면에 관해 분기할 때  섬유들(36)이 원통형 외면(18)을 따르도록 헤드박스(26)와 하류롤(15)사이의 재로부터 분리된 셀룰로우스 섬유들(36)을 이동시키기 위해 하류롤(15)의 원통형 외면(18)에 인접하게 배치된다. 
     독터(38)는 하류롤(15)의 외면(18)으로부터 섬유들(36)을 독터링(doctoring) 하기 위해 외면(18)에 인접하게 배치된다.  횡 컨베이어(40)는 벨트(20)에 관해 횡으로 섬유들(36)을 이송하기 위해 외면(18)에 인접 배치되므로  재로부터 분리된 섬유들은 재생 웨브를 형성하기 위해 계속하여 사용될 수 있다.
